Risk Factors for Type 2 Diabetes Mellitus Complications as a Basis for Prevention Efforts at Malahayati Islamic Hospital Medan
type: item
description: Diabetes mellitus is a non-communicable disease with a steadily increasing number of cases. This increase is due to significant complications that can lead to reduced life expectancy, paralysis, and an increased economic burden. This study aimed to identify risk factors for type 2 diabetes mellitus complications to inform prevention efforts at Malahayati Islamic Hospital in Medan. This observational analytical study used a case-control design. The study population consisted of diabetes patients registered at Malahayati Islamic Hospital in Medan. There were 120 respondents in total, with 60 in the case group and 60 in the control group. Data were collected through direct interviews at the hospital. Univariate and bivariate analyses were used for data analysis. The results showed that patients with diabetes mellitus (DM) for ≥5 years were 7.1 times more likely to develop complications, patients with an obese body mass index (BMI) were 3.9 times more likely to develop complications, patients with irregular blood sugar control were 2.9 times more likely to develop complications, and patients who did not adhere to their medication were 2.3 times more likely to develop complications. Duration of suffering, obesity, irregular blood sugar control, and noncompliance with treatment are risk factors for type 2 diabetes mellitus complications.

The Role of Development Communication in Enhancing Community Involvement in Bur Telege Tourism Management
type: item
description: This study examines the critical factors influencing the sustainability of community-based tourism management in Bur Telege, Aceh Tengah, and investigates the effectiveness of development communication in promoting community engagement. The study is based on the assumption that genuine local participation in tourism governance requires open, transparent, and inclusive communication. Using an Explanatory Sequential Mixed Methods (ESMM) design, the research involved 100 respondents through a Likert-scale questionnaire, complemented by in-depth interviews with six key informants. Quantitative findings indicate that development communication has a significant impact on community engagement, with a Pearson correlation value (r = 0.61; p < 0.01) and explaining 37% of the variance in participation levels (R² = 0.37). However, the mean score suggests that communication effectiveness remains relatively low (mean = 2.1), particularly in meeting attendance (1.7) and the timeliness of information delivery (1.9). Qualitative analysis using NVivo identified several supporting factors, including government support through workforce certification programs, the use of simple digital media (such as WhatsApp), religion-based social capital, and village meetings. Conversely, significant barriers include the absence of a comprehensive tourism development blueprint, nepotism in recruitment practices, community pragmatism, lack of transparency in village-owned enterprise (BUMDes) management, and limited representation of marginalized groups. These findings underscore that effective development communication is a crucial instrument for strengthening long-term community engagement. Therefore, digital-based, transparent, and participatory communication strategies are essential to ensure sustainable tourism management.

Dissemination of Seagrass Density Information from Object-Based Image Analysis (OBIA) Mapping to Pengudang Coastal Community
type: item
description: Pengudang Village, Bintan Regency, Riau Islands, is a coastal area that hosts seagrass ecosystems with high biodiversity. However, this area is increasingly experiencing degradation pressures due to climate change and anthropogenic activities. The limited public knowledge regarding the condition of seagrass ecosystems has become a major obstacle to community-based conservation efforts in the region. This community service activity aimed to disseminate information on seagrass density mapping results using the Object-Based Image Analysis (OBIA) technology to the coastal community of Pengudang. The mapping was conducted at 59 survey points distributed across the shallow waters of Pengudang Village in October 2025. The results identified seven seagrass species with a total coverage area of 344.26 hectares, of which approximately 92% fell into the high-density category. The dissemination of the mapping results was carried out in December 2025 using an interactive outreach method supported by visual media and infographics, and was evaluated through questionnaires distributed to 10 respondents. The evaluation results showed that all assessment indicators were within a score range of 3.7–4.0, categorized as Very Good, with no respondents expressing disagreement regarding either the material or the implementation of the activity. This activity demonstrates that a dissemination approach based on modern mapping technology, delivered through participatory and contextual methods, is effective in improving public understanding, awareness, and conservation motivation among coastal communities toward seagrass ecosystems.

Integrated Work Mapping to Optimize Small-Scale Tofu Production
type: item
description: This study aims to identify inefficiencies in the tofu production process in small-scale tofu industries in Padang City, West Sumatra, and to propose improvements through an integrated work mapping approach. The analysis employs five types of work mapping tools, namely the operation process chart, flow process chart, layout flow diagram, man–machine chart, and right-hand–left-hand chart. The research method used is a qualitative case study conducted through direct observation, production cycle time measurements, and semi-structured interviews with the owner and workers. The results show that the total production cycle requires approximately 390 minutes, with the soaking stage (120 minutes) and molding stage (60 minutes) being the most time-consuming processes. The flow process chart identifies seven transportation activities with a total time of 16 minutes. Meanwhile, the man–machine chart reveals an imbalance in resource utilization, where the grinding machine operates for 33.1 minutes while the operator is active for only 3.1 minutes, resulting in 30 minutes of idle time. The right-hand–left-hand chart also indicates the dominance of right-hand movements in the cutting process, suggesting ergonomic inefficiency. The novelty of this study lies in the integration of five work mapping tools within a single analytical framework to provide a comprehensive evaluation of process flow, spatial layout, human–machine interaction, and manual motion patterns. The proposed improvements include workflow optimization, task redistribution, ergonomic workstation redesign, and the development of standard operating procedures (SOPs) to enhance efficiency and productivity in small-scale tofu industries.

Increasing Community Awareness of Sidamukti Village Community Through Waste Literacy
type: item
description: Sidamukti Village in Sukaresmi District, Pandeglang Regency, still faces challenges in waste management. Poorly managed waste has the potential to disrupt the sustainability of residents’ livelihoods. Low levels of waste literacy and community participation are considered the main causes of this problem. This Community Service (PkM) activity aims to increase residents’ knowledge and awareness in managing waste and maintaining environmental sustainability. Using the Participatory Action Research (PAR) method, the community was actively involved in every stage, starting from problem identification, planning, to the implementation of concrete actions. Waste literacy activities were conducted through socialization programs and beach clean-up actions as participatory learning activities involving community leaders, PKK members, youth organizations (Karang Taruna), and local residents. The results show that this approach successfully improved community perceptions and behaviors toward the environment. However, to maintain the consistency of these behavioral changes, adequate waste management facilities and continuous education are required, particularly for younger generations and school children.

Optimizing Natural Dyeing Processes to Improve Product Quality Ecoprint-Based Creative Industries that Support Sustainable Economic Growth
type: item
description: This community service activity aims to improve the product quality and business capacity of ecoprint MSMEs through the optimization of natural dyeing processes based on ketapang leaves (Terminalia catappa) and sappanwood (Caesalpinia sappan), integrated with strengthening business management and digital marketing. The implementation method employed a participatory approach through several stages, including socialization, training on natural dye extraction, practice of dyeing and color fixation, business management training, as well as monitoring and evaluation. The results indicate a significant improvement in the partners’ capacity. Optimization of the mordanting and fixation processes improved the color fastness of products from a low category to a moderate–high category based on washing and rubbing tests. Production efficiency also increased, as indicated by the reduction of production time from approximately seven days to four to five days per production cycle and an increase in production capacity of around 30%. In addition, product diversification of ecoprint products was achieved, resulting in various derivative products such as eco-tik, tote bags, and ready-to-wear clothing, along with increased digital marketing activities through social media and marketplaces. The novelty of this program lies in the integration of technical innovation in optimizing natural dyes with the empowerment of business management and digital marketing for creative MSMEs. This integrated approach has proven effective in improving product quality, production efficiency, and business competitiveness. The findings indicate that strengthening production capacity based on local resources, supported by business management and digital marketing, can serve as a sustainable empowerment model for creative MSMEs. This program contributes to the achievement of the Sustainable Development Goals (SDGs), particularly Goal 8, by increasing business productivity, expanding market access, and encour…

Web-Based CRM Implementation for Improving Agricultural Product Sales Strategy
type: item
description: The development of information technology encourages business actors, including Micro, Small, and Medium Enterprises (MSMEs), to utilize information systems to improve operational efficiency and customer relationship management. Customer Relationship Management (CRM) is a strategy used to manage interactions with customers in order to increase customer satisfaction and loyalty. However, many MSMEs still record customer data and sales transactions manually, resulting in less effective data management processes. UD Sri Tani is a business engaged in the sale of agricultural products that still manages customer data, product inventory, and sales transactions manually. This condition causes difficulties in monitoring customer relationships and developing effective sales strategies. Therefore, this study aims to implement a web-based Customer Relationship Management (CRM) system to improve customer management and support sales strategies. The research method used includes system requirements analysis, system design, system implementation, and system testing. Data collection was conducted through observation, interviews, and the distribution of questionnaires to 39 respondents consisting of customers and business managers. System testing was carried out using the Black Box Testing method to ensure that all system functions operate according to user requirements. The results of the study indicate that the developed CRM system is capable of integrating customer data, product data, and sales transactions in a centralized manner. Based on 15 testing scenarios, all system functions showed a 100% success rate, indicating that the system operates properly according to user needs. The implementation of this system helps business owners manage customer relationships more effectively and supports the improvement of agricultural product sales strategies at UD Sri Tani.

Digital Literacy Enhancement for Expanding the Market Reach of Fishermen in Kilang Village
type: item
description: Traditional fishermen are micro-scale enterprises with the potential to absorb labor and reduce poverty in coastal areas. However, they often face several challenges, such as low sales turnover that is not proportional to operational costs, limited innovation in marketing strategies, and the long distance to traditional markets. These conditions are also experienced by fishermen in Kilang Village, Leitimur Selatan District, Ambon City. Therefore, this community service activity aims to improve fishermen’s digital literacy in order to expand market reach through the use of digital technology. The implementation method includes an initial survey and problem mapping, administration of a pre-test, socialization and discussions on the digitalization of fish markets, and a post-test to evaluate participants’ improved understanding. The activity was conducted from March 23 to 25, 2025, at the Kilang Village Office and involved 27 local fishermen. A descriptive quantitative method was used to analyze pre-test and post-test data to assess changes in participants’ level of understanding. The results indicate an increase in participants’ understanding of the use of digital platforms for marketing fishery products, as shown by the increase in the average score from 40 in the pre-test to 80 in the post-test. These findings suggest that digital literacy can serve as an initial step in encouraging fishermen to adopt digital markets, thereby improving marketing efficiency, expanding market access, and supporting the sustainability of fishing businesses in coastal areas.

Integrated Green Mining Technology Package for Emission Reduction
type: item
description: Mine decarbonisation studies still tend to evaluate electrification, energy efficiency, and renewable energy as separate interventions; therefore, evidence on integrated operational deployment remains limited, particularly for medium-scale open-pit mines in developing countries. This study evaluates whether an integrated green mining package can reduce Scope 1 and 2 emissions without undermining day-to-day operational reliability. Using a Design Science Research approach, the study developed and piloted a package consisting of trolley-assist haulage, battery-electric support vehicles, variable speed drives for dewatering pumps, an energy management system, and a solar PV–battery microgrid. Baseline and pilot performance were compared over two three-month periods using fuel logs, electricity meters, telematics, and PV/battery logger data. Emissions were calculated from activity data and IPCC-based emission factors, while renewable integration was assessed using HOMER Pro simulation. Diesel consumption declined from 4,000,000 L to 3,256,000 L (−18.6%), and purchased electricity decreased from 10,000 MWh to 9,060 MWh (−9.4%). The PV system generated 4,050 MWh, supplying about 30.9% of pilot-period electricity demand. Total Scope 1 and 2 emissions fell from 18,920 tCO₂e to 16,155 tCO₂e (−14.6%). The pilot also showed that electrification increased on-site electricity demand, making EMS coordination and renewable supply critical enabling conditions rather than optional add-ons. The novelty of this study lies in field-validating an integrated decarbonisation package instead of a single technology. The findings provide operational-scale evidence for medium-scale mines and support policies on electrification-ready microgrids, performance-based incentives, and standardised Scope 1 and 2 reporting.

Renewable Energy Education through Solar-Powered Toy Car Assembly Activities for Junior High School Students
type: item
description: Renewable energy sources are a solution to fossil energy sources, which are increasingly depleting every day. Renewable energy has various types; however, the most widely used at present is solar energy, commonly referred to as solar power generation (photovoltaic systems). The development of solar power in Indonesia has begun to be implemented in several sectors to support government programs, particularly national energy security. Considering the importance of renewable energy, early socialization and education are needed, especially for junior high school students. Early education is expected to raise students’ awareness of the importance of environmental preservation in maintaining renewable energy resources provided by nature. To make the educational process more engaging, a hands-on practice method was applied. In this community service activity, students assembled solar-powered toy cars so that the cars could operate. This activity aimed to directly involve students in the use of renewable energy and to help them understand how renewable energy can be applied in simple applications. The results show that students were able to complete the assembly of solar-powered toy cars; 48.28% of students rated the activity as very beneficial, 48.28% as beneficial, and 3.45% as moderately beneficial. Based on these results, it can be concluded that the community service activity was successfully implemented.

A Weighted Engineering Geological Framework for Evaluating Post-Mining Land Reclamation Suitability Based on Slope, Material Properties, and Drainage
type: item
description: Post-mining reclamation often underperforms when land is considered ready for revegetation without prior engineering geological screening. This study develops and demonstrates a weighted engineering geological framework for evaluating reclamation suitability based on slope condition, material properties, and drainage performance. A descriptive-evaluative design was used by combining land-unit delineation, field observation parameters, basic geotechnical indicators, drainage appraisal, and weighted scoring. To transparently demonstrate the analytical model, simulated but technically plausible data were assigned to four engineering geological zones. The model weights slope at 40%, material properties at 35%, and drainage at 25%. The resulting suitability scores classify Zone A as very suitable (87.2), Zone B as moderately suitable (72.6), Zone C as conditionally suitable (56.9), and Zone D as unsuitable (41.6). The novelty of the study lies in operationalizing slope, material, and drainage variables into a transparent zone-based suitability score, and in positioning engineering geology as the first diagnostic layer of reclamation planning rather than a post-planting correction. The framework helps identify dominant limiting factors and supports staged interventions such as regrading, drainage rehabilitation, material improvement, and phased revegetation. The model is suitable as a pre-screening tool and should be calibrated with site-specific field data in future applications.

Evaluating the Effectiveness of a Pilot-Scale Subsurface-Flow Constructed Wetland for Reducing Iron, Manganese, and Sulfate in Acid Mine Drainage from Former Coal Mining Areas
type: item
description: Acid mine drainage from former coal mining areas is characterized by low pH and elevated concentrations of dissolved metals and sulfate, which may degrade receiving-water quality and create long-term environmental risk. This study evaluated the effectiveness and applied relevance of a pilot-scale subsurface-flow constructed wetland in improving acid mine drainage quality by increasing pH and reducing iron, manganese, and sulfate. The novelty of the study lies in the integrated use of gravel, sand, limestone, organic support media, and wetland vegetation within a pilot unit designed for post-mining rehabilitation conditions, while assessing pH, Fe, Mn, and sulfate simultaneously as key indicators of treatment performance. A quasi-experimental pretest–posttest approach was used by comparing influent and effluent quality after treatment through the wetland media. The influent had a pH of 3.2, Fe of 12.50 mg/L, Mn of 8.20 mg/L, and sulfate of 420.00 mg/L. After treatment, the effluent pH increased to 6.1, while Fe decreased to 3.40 mg/L, Mn to 2.70 mg/L, and sulfate to 180.00 mg/L. The corresponding removal efficiencies were 72.80% for Fe, 67.07% for Mn, and 57.14% for sulfate. These findings indicate that pilot-scale subsurface-flow constructed wetlands can provide a simple, low-energy, and environmentally compatible option for post-mining water management and may support practical rehabilitation strategies where long-term chemical dosing is difficult to sustain.

Flexing Practices among Public University Students in Medan on Instagram
type: item
description: This study examines the practice of flexing among public university students in Medan on Instagram as part of self-presentation in digital spaces. The study uses a dramaturgical perspective to understand how flexing is displayed as a form of sharing activities, experiences, and moments that reflect lifestyle and digital identity. This research adopts a qualitative approach with a phenomenological method to explore the subjective experiences of informants. Data were collected through in-depth interviews, digital observation, and content documentation from students selected through purposive sampling. Data were analyzed using a qualitative analysis model through data reduction, data display, and conclusion drawing. The findings show that flexing practices are not solely interpreted as showing off wealth or luxury, but are more commonly expressed through sharing daily activities, experiences, and selected moments on Instagram. These practices are closely related to efforts to build self-image and gain social recognition through audience responses such as likes and comments. Flexing thus becomes part of students’ self-presentation in constructing identity and negotiating social position in digital spaces.

Development and Pilot Evaluation of Sensor-Based Environmental Monitoring and Green Technology Interventions for Pollution Reduction in Indonesian Mining Sites
type: item
description: This study develops and pilot-tests an integrated package of environmentally friendly operational interventions and a sensor-based environmental monitoring system at two mining locations in Indonesia. The research used a pilot multiple-site case study over three months, combining field observation, document review, and repeated measurement of water, air, and soil quality indicators. The analytical focus was on descriptive before–after comparison and compliance-gap assessment, because the pilot dataset was limited to two sites and did not justify inferential statistics. The results show that PM2.5 declined from 58 to 41 µg/m³ at Mine Location A (29.3%) and from 65 to 55 µg/m³ at Mine Location B (15.4%) after intervention. However, several parameters remained above or below the required benchmarks, including turbidity (15–25 NTU versus ≤5 NTU), dissolved oxygen (3.8–4.5 mg/L versus ≥5 mg/L), arsenic (10–12 ppb versus ≤5 ppb), and soil organic matter (2.0–2.5% versus ≥3%). These findings indicate that the monitoring system is effective for early detection and operational feedback, whereas the green technology interventions produced only partial environmental improvement. The study contributes a practical framework for integrating site-level monitoring, threshold-based evaluation, and adaptive environmental management in Indonesia's mining sector. The main implication is that sensor deployment should be scaled together with stronger mine-water treatment, dust suppression, calibration routines, and compliance reporting requirements.

Digital Communication of PLN UP3 Sibolga in the Dissemination of Public Service Information through Social Media
type: item
description: This study aims to analyze the digital communication of PLN UP3 Sibolga in disseminating public service information through social media, focusing on the role of Artificial Intelligence (AI) and human touch in public relations practices. While previous studies have examined digital communication and AI in public relations, studies that integrate both aspects in local public service contexts remain limited. This research employs a qualitative descriptive approach, with data collected through in-depth interviews with public relations personnel and documentation of social media content. The results show that digital communication has been utilized to support the dissemination of public service information, with AI functioning as a supporting tool to improve efficiency in content production. However, human involvement remains essential to ensure clarity, empathy, and appropriateness of the message. In addition, digital communication through social media has not fully replaced the public's need for direct communication. Therefore, effective public service communication requires the integration of technological utilization with a humanistic approach to ensure that information is properly understood by the public.

Students’ Perspectives on Influencer Endorsements in Marketing Local G2G Skincare Products on Instagram
type: item
description: This study aims to analyze students’ perspectives on influencer endorsement in the marketing of local G2G skincare products on Instagram. The increasing use of influencers in digital marketing strategies reflects a shift in marketing communication patterns; however, limited studies have specifically examined how students, as consumers, interpret influencer endorsement in the context of local products. This research employs a qualitative descriptive approach, with data collected through in-depth interviews with students of Universitas Islam Negeri Sumatera Utara who actively use social media. The findings indicate that influencer endorsement is perceived as a factor influencing interest and trust in products, particularly when influencers are considered credible, relevant to the product, and demonstrate authentic usage experiences. However, students do not passively accept endorsement content; instead, they engage in critical evaluation of the information presented. Furthermore, trust in the product is influenced not only by influencers but also by personal experience, peer reviews, and brand reputation. This study highlights that the effectiveness of influencer endorsement in marketing local skincare products depends not merely on influencer popularity, but on perceived credibility and relevance from the consumers’ perspective.

Normalization of Bullying on TikTok
type: item
description: This study examines the normalization of bullying on TikTok as a form of symbolic violence and explores how audience reception contributes to its social legitimation. Using a qualitative content analysis approach, the study analyzes comments and interactions from selected TikTok videos that contain derogatory expressions, symbolic labeling, and identity-based attacks. The data were collected through purposive sampling and analyzed using coding, categorization, and interpretive analysis based on Stuart Hall’s audience reception framework. The findings show that bullying on TikTok operates not only through direct insults but also through sarcasm, stereotypes, symbolic labeling, and visual cues that subtly degrade individuals. The normalization process occurs through repetitive comments, collective interactions, and digital engagement, such as likes and replies, which function as mechanisms of social validation. Audience reception is dominated by hegemonic and negotiated readings, where derogatory expressions are accepted as humor or ordinary interaction, while oppositional readings remain limited. These findings highlight the need to strengthen critical digital literacy so that users are better able to recognize, resist, and respond to symbolic forms of bullying in digital interactions.

type: item
description: The gap in digital literacy capacity, entrepreneurship, and local economic governance remains a structural challenge faced by most Indonesian communities, particularly micro, small, and medium enterprise (MSME) actors, Village-Owned Enterprise (BUMDes) managers, and communities with limited access to quality education. This article aims to describe, analyze, and document the effectiveness of four University-Based Community Service (PBMU) programs implemented by Universitas Muhammadiyah Siber (SiberMU) during the November–December 2025 period. The four programs encompass plant-based entrepreneurship training, BUMDes governance training, digital literacy education on the brain rot phenomenon, and the development of an online Learning Management System (LMS) platform at 4u.mooc.or.id. A descriptive qualitative case study approach was employed, with data collected through pre-tests, post-tests, participatory observation, and participant satisfaction surveys. The results indicate that participants' technical competence in entrepreneurship improved by over 80%, understanding of BUMDes governance was significantly strengthened, digital literacy awareness increased among more than 100 webinar participants, and the LMS platform was successfully launched with eleven free e-courses accessible to the wider public. The study concludes that a multidisciplinary, online, and outcome-oriented community service approach can produce measurable transformative impacts on target groups, and recommends strengthening post-program mentoring mechanisms and multi-stakeholder collaboration to sustain long-term program outcomes.

Strengthening the Role of Corporate Social Responsibility (CSR) as a Business Law Instrument in Addressing Flood Impacts in Sumatra
type: item
description: The massive floods in Sumatra in 2025–2026 resulted in significant loss of life and economic damage, driven by a combination of extreme weather and environmental degradation linked to business activities. This situation underscores that disaster management is not solely the responsibility of government, but also of the private sector. In Indonesian business law, Corporate Social Responsibility (CSR) constitutes a legal obligation for companies to address the social and environmental impacts of their operations. Therefore, strengthening CSR is crucial as an instrument for sustainable flood mitigation and recovery. This study aims to analyze the role and position of CSR in flood management in Sumatra, to reinforce CSR policies so they contribute more effectively to prevention and mitigation, and to examine corporate accountability when CSR is not optimally implemented, leading to environmental damage and increased flood risk. This research adopts a normative legal method with a descriptive-analytical approach, using statutory and case-based analysis. The data consist of secondary sources, including primary, secondary, and tertiary legal materials, collected through literature and document review and analyzed qualitatively. CSR in flood management functions as a strategic legal instrument for environmental prevention and recovery. Its optimization is essential to strengthen environmental protection and the resilience of flood-prone areas. CSR must shift from a charitable approach to a risk- and sustainability-based framework integrated with environmental and disaster law. Stronger ESG regulation, oversight, and reporting are necessary. Corporate accountability for suboptimal CSR includes administrative, civil, and criminal sanctions, alongside governance and reputational consequences, grounded in precautionary and polluter-pays principles.

The Dynamics of Job Creation Law Implementation in Addressing Digital Disruption
type: item
description: The rapid advancement of digital technology has fundamentally transformed business legal systems, demanding more adaptive and responsive regulatory frameworks. In Indonesia, the Job Creation Law was enacted through an omnibus law approach to simplify regulations and support the digital economy; however, its implementation continues to face significant challenges, including regulatory disharmony, normative gaps, and legal uncertainty. This study analyzes the dynamics of the Job Creation Law's implementation in responding to digital disruption in Indonesia's business law sector, along with the challenges encountered and the government's role in regulatory harmonization. Using a normative legal method with a descriptive-analytical approach, this study employs statutory and case-based approaches, drawing on secondary data analyzed qualitatively. The findings indicate that while the Job Creation Law has successfully shifted business law toward a more adaptive, risk-based regulatory paradigm, its implementation remains constrained by cross-sectoral regulatory fragmentation, jurisdictional limitations in the borderless digital economy, and insufficient institutional capacity and digital legal infrastructure. The harmonization of business law in the digital era ultimately depends on policy consistency, inter-agency synergy, and a sustained balance between fostering innovation and ensuring adequate legal protection for all stakeholders.

Maqashid Syariah-Based Optimization of Cash Waqf
type: item
description: Cash waqf (wakaf uang) represents a significant Islamic philanthropic instrument with considerable potential for productive economic empowerment and poverty alleviation. Despite an estimated national potential exceeding IDR 180 trillion annually, actual realization remains below 1% due to complex structural barriers. This study aims to analyze the strategic role of cash waqf in productive economic empowerment while identifying key constraints and optimization strategies within a maqashid syariah framework. Employing a qualitative descriptive-analytical systematic literature review, the research reviewed legislation, fatwas, institutional reports, and peer-reviewed articles published between 2015–2025. Findings reveal three principal results: (1) cash waqf possesses a robust legal foundation through Law No. 41 of 2004 and MUI Fatwa No. 2 of 2002, yet a significant implementation gap persists between legal norms and field practice; (2) primary constraints are systemic and interrelated, encompassing low public literacy, weak nadzir capacity, insufficient fiscal incentives, and digitalization deficits; and (3) effective optimization requires an integrated ecosystem approach comprising governance strengthening, digital platform development, and cross-sectoral institutional synergy. The novelty of this study lies in its integration of legal, institutional, technological, and literacy dimensions within a single unified analytical framework grounded in maqashid syariah — an approach not yet comprehensively undertaken in prior literature. The principal contribution is the formulation of an operational maqashid syariah-based cash waqf governance model relevant to the Indonesian context, alongside systemic policy recommendations actionable by key stakeholders.

Integration of Energy Quality and Financial Feasibility in the Production of Oil Palm Frond Chips and Pellets
type: item
description: Indonesia, as the world’s largest palm oil producer, generates significant quantities of oil palm frond (OPF) biomass that remain underutilized. This study evaluates the technical characteristics and economic feasibility of converting OPF into energy products in the form of chips and pellets. Laboratory analyses including proximate, ultimate, and calorific value tests were conducted to assess fuel quality, followed by a techno-economic evaluation using a 15-year investment horizon and an 11% discount rate. Results show that pelletization improves fuel properties, particularly by reducing moisture content and increasing calorific value under actual conditions. The higher heating value (HHV) of pellets reached 3,962 kcal/kg under air-dry conditions, compared to 1,746 kcal/kg for chips. On a dry ash-free basis, the calorific values of both products were comparable, indicating that moisture content significantly influences actual energy performance. Economic analysis indicates that pellet production under coal price equivalence schemes does not achieve attractive financial returns, with internal rates of return (IRR) below the discount rate and payback periods exceeding project lifetime. Sensitivity analysis suggests that a selling price of Rp1,000,000 per ton or a calorific value above 5,300 kcal/kg is required to reach financial feasibility. In contrast, chip production with low calorific value is economically unviable; however, improving chip quality to 4,060 kcal/kg results in a financially feasible scenario, achieving an IRR of 32.3% and payback within four years. The findings highlight that product form, energy quality, and market pricing mechanisms critically determine the viability of OPF-based bioenergy development.

Toward Effective Vocabulary Acquisition in EFL Classrooms
type: item
description: This study examined the effect of the differentiated learning approach on EFL students’ vocabulary acquisition at the junior high school level. Vocabulary is a fundamental component of language learning; however, many EFL students still experience difficulties due to differences in readiness levels, interests, and learning profiles. Although differentiated learning has been widely discussed in previous studies, its empirical implementation in improving vocabulary acquisition in junior high school EFL contexts remains limited. Therefore, this study aimed to determine whether the differentiated learning approach significantly affects students’ vocabulary acquisition. This study employed a quantitative method using a quasi-experimental design with a non-equivalent control group. The population consisted of all ninth-grade students at UPT SMPN 3 Kelara, and the sample was selected through purposive sampling, involving two classes as the experimental and control groups. Data were collected through pre-tests and post-tests, and analyzed using statistical tests to measure the differences between groups. The findings revealed that the experimental group demonstrated significantly greater improvement compared to the control group. The mean score of the experimental group increased substantially from 30.71 in the pre-test to 65.95 in the post-test, indicating the effectiveness of differentiated learning in enhancing students’ vocabulary acquisition. In conclusion, the differentiated learning approach significantly improves EFL students’ vocabulary acquisition and provides an effective alternative to conventional teaching methods in promoting student-centered learning at the junior high school level.

The Potential of Flavonoid Compounds in Wet Organic Waste as Antibacterial Agents
type: item
description: Flavonoid compounds are natural polyphenolic bioactive compounds known to possess significant biological and antibacterial activities, as well as added value. These compounds have the ability to inhibit the growth of pathogenic bacteria that can cause health disorders in humans. Since flavonoids cannot be produced by the human body, their sources must be obtained from food, beverages, or other external sources. Wet organic waste, such as fruit peels, vegetable scraps, and agricultural waste, is reported to still contain flavonoid compounds in varying amounts, depending on the type of waste. By employing a systematic literature review (SLR) method on previous studies published in indexed national and reputable international journals, the potential of flavonoid compounds in wet organic waste can be evaluated. This includes their mechanism of action, factors influencing the effectiveness of their antibacterial activity, and their relevance to human health. The results of the review indicate that flavonoid compounds derived from wet organic waste are capable of inhibiting Gram-positive and Gram-negative bacteria commonly associated with infections, such as Staphylococcus aureus and Escherichia coli. Factors such as the type of waste material, extraction method, and extract concentration influence the effectiveness of the flavonoids' antibacterial activity. Furthermore, the utilization of flavonoids from organic waste aligns with the circular economy paradigm in supporting sustainable waste management. It can be concluded that flavonoids from wet organic waste hold great potential as natural antibacterial agents that support human health while simultaneously providing an innovative solution for sustainability-based waste management.

Community-Based Child Trauma Recovery Strategies After Flash Floods in Aceh Tamiang–Langkat
type: item
description: Flash floods cause not only physical damage but also psychological impacts on children as a vulnerable group. Although various post-disaster trauma recovery programs have been developed, community service studies that integrate child psychosocial intervention, parental involvement, and local volunteer capacity building within a community-based recovery model remain limited. This community service program aimed to implement a community-based trauma recovery strategy for children affected by flash floods in the Aceh Tamiang–Langkat region. The program involved 35 children aged 6–12 years who were directly affected by the disaster. A participatory approach was applied through initial assessment, psychosocial intervention, psychoeducation, and pre-post intervention evaluation. Data were collected using a simple psychosocial observation sheet covering indicators of anxiety, emotional expression, social interaction, sense of safety, and child participation, supported by brief interviews with parents and local volunteers. The data were analyzed descriptively by comparing children’s conditions before and after the intervention. The intervention consisted of play therapy, drawing, storytelling, collaborative games, and structured group activities. The results showed that 74% of children experienced reduced anxiety, 80% demonstrated improved emotional expression, and 77% showed increased social interaction. In addition, the involvement of parents and local volunteers strengthened social support and contributed to program sustainability. These findings indicate that community-based trauma recovery can serve as a relevant, practical, and sustainable psychosocial intervention model for addressing children’s psychological needs in post-disaster contexts.

Analysis of the Potential Use of Mining Waste as Raw Material in the Production of Environmentally Friendly Construction Materials
type: item
description: This study evaluates the feasibility of using three mining-related waste materials, namely tailings, steel slag, and fly ash, as alternative raw materials for environmentally friendly construction products. Although these wastes have been widely examined in previous studies, comparative experimental evidence under a unified testing scheme remains limited, particularly in the Indonesian construction context where material variability and standardization constraints affect field adoption. The novelty of this study lies in positioning the three waste types within the same performance framework by examining compressive strength, water absorption, and corrosion-related durability indicators against a conventional control mixture. Laboratory tests were conducted using a screening-scale experimental design. Compressive strength testing followed the principle of ASTM C39/C39M, water absorption testing followed ASTM C642, and corrosion-related mass/thickness loss evaluation was adapted from laboratory immersion corrosion principles. The results indicate that slag-based specimens showed the highest performance among the waste-based materials, with 28-day compressive strength of 42.1 MPa and water absorption of 3.7%. Fly ash-based specimens reached 36.5 MPa but showed higher water absorption of 6.8%, while tailing-based specimens reached 34.0 MPa with 4.7% water absorption. Compared with the conventional control specimen, the slag-based material achieved approximately 93.6% of the control compressive strength, suggesting its technical potential for selected construction applications after durability and environmental safety validation. The study contributes a comparative performance map and a methodological basis for further optimization of mining waste utilization in sustainable construction materials.
