Livestock production in rural communities relies heavily on the availability and quality of animal feed. In Aek Korsik Village, Asahan Regency, farmers continue to use manual methods to chop forage, which are time-consuming, inconsistent, and physically demanding. To address these issues, a portable forage chopper machine was designed and introduced through a community service program (KKN). The machine features a compact mechanical system powered by a small motor, making it lightweight, mobile, and easy to operate in various conditions. The implementation process included three stages: machine development, field testing, and community training. During testing, the machine efficiently processed forage materials like grass, corn stalks, and agricultural residues, producing uniform feed sizes much faster than manual methods. Farmers reported reduced workload, improved availability of chopped forage, and better livestock feeding practices. The portable design allowed the equipment to be shared among farming groups, fostering cooperation. This study underscores the role of appropriate technology in addressing rural agricultural challenges. By integrating engineering innovation with community service, the portable forage chopper machine enhances technical efficiency and socio-economic empowerment for farmers. Future improvements should focus on durability, cutting capacity, and sustainable energy alternatives to better meet the needs of smallholder farmers.

This study aims to assess the effectiveness of the Jakpreneur program in reducing unemployment in South Jakarta. Jakpreneur is a strategic initiative launched by the Jakarta Provincial Government as a concrete effort to empower Micro, Small, and Medium Enterprises (MSMEs). This program is designed with various forms of support, such as skills training, business mentoring, legal licensing facilitation, product marketing support, and easy access to capital. This aims to create an inclusive and sustainable entrepreneurial ecosystem, especially amidst the complex challenges of the urban economy and the ongoing unemployment rate. However, in its implementation on the ground, the program's effectiveness still faces several obstacles. One of the main problems identified is the suboptimality of information technology-based training. Many participants have not yet mastered basic digital skills, making it difficult to keep up with developments in training methods that rely on technology. In addition, the low level of responsiveness of program facilitators to participant needs, as well as the limited digital literacy of MSMEs, also hinders maximizing the benefits of this program. This study uses a descriptive qualitative approach with data collection techniques through in-depth interviews, participant observation, and documentation studies. The findings indicate that, despite some shortcomings, the Jakpreneur program has been generally successful in improving participants' entrepreneurial knowledge and skills, reaching the right target audience, and having a tangible impact on increasing business capacity and reducing unemployment. Therefore, strengthening outreach, improving the quality of digital training, and providing more active and responsive mentoring is necessary to further enhance the program's effectiveness.

The problem of organic waste remains a serious issue in Indonesia, including in rural areas. Jatitamban Village, Bondowoso Regency, faces similar challenges due to household waste and residual by-products from local small enterprises producing tape and cassava chips, which are not yet optimally managed. The Community Service Program (KKN) of the University of Jember implemented an initiative to empower village youth through maggot cultivation as an environmentally friendly and economically valuable solution for organic waste management. This study employed a Community-Based Research (CBR) approach by engaging local youth as active partners in every stage of the program, including observation, planning, socialization, technical training, workshops, and monitoring. The results indicate that Black Soldier Fly (BSF) maggot cultivation serves as an effective strategy to reduce the volume of organic waste while producing value-added products such as alternative animal feed and organic fertilizer. The involvement of youth not only enhanced their knowledge and skills but also fostered environmental awareness and created new entrepreneurial opportunities. Furthermore, the program successfully established a solid and independent youth group capable of sustainably managing organic waste through maggot cultivation practices. The implications of this program extend beyond environmental improvement to promoting village economic independence through the utilization of organic waste. Therefore, youth empowerment through maggot cultivation can serve as a strategic model for sustainable waste management as well as strengthening community capacity in rural areas.

Criminal liability in modern law is built on the assumption that every individual is a rational and autonomous moral agent. However, neuroscientific evidence suggests that structural disruption of the amygdala and prefrontal cortex significantly impairs the capacity to judge actions ethically. This study aims to analyze the influence of neurological disorders on an individual's moral capacity and to formulate legal parameters for assessing criminal liability based on actual capacity. The research method employed normative legal research with a conceptual approach. The results indicate that perpetrators with dysfunction in the amygdala-PFC circuit experience a degradation of moral capacity that weakens the basis for the formation of mens rea in a substantive sense and falls outside the reach of legal systems that still rely on a model of responsibility based on the assumption of universal free will. The criminal legal system, in its current form, lacks a precise evaluative mechanism to distinguish between perpetrators with impaired moral control and those acting deliberatively. In this situation, the construction of criminal liability cannot be standardized, and reformulation of evaluation instruments is necessary to avoid sentencing bias against individuals with structural impairments in ethical capacity.

The modern doctrine of criminal responsibility is built on the premise of free will and individual deliberative capacity. However, advances in neurogenetics, particularly findings regarding MAOA-L gene expression, have presented a structural disruption to this framework. The MAOA-L gene has been empirically associated with impaired impulse regulation and increased aggressive responses, particularly in combination with childhood trauma. This study aims to evaluate how MAOA-L gene expression influences the capacity for criminal responsibility and to analyze the tension between classical legal constructs and biological determinants within the structure of culpability. The research method employed normative research with a conceptual approach. The results indicate that the dichotomy-based mens rea doctrine fails to accommodate the degree of control capacity shaped by neurobiological structures. MAOA-L cannot be treated as a basis for forgiveness, but rather serves as an evaluative variable in assessing the spectrum of legal responsibility. In this position, criminal law maintains the principle of individual responsibility but formulates it through a new framework based on actual capacity rather than a universal voluntaristic assumption. This reformulation is necessary to avoid disproportionate attribution of blame and to allow criminal law to move toward a system that is more adaptive to biological realities without falling into determinism.

This study analyzes the impact of urban sprawl on groundwater reserves in Kendari City using the platform Google Earth Engine (GEE) with analysis period of 2000 and 2024. Urban sprawl is characterized by an increase in built-up land area estimated through the Normalized Difference Built-Up Index (NDBI), while groundwater reserves are projected through estimated baseflow groundwater runoff obtained from FLDAS ( Famine Early Warning Systems Network Land Data Assimilation System ) data. The results show a significant increase in NDBI values from 2000 to 2024, indicating a massive expansion of built-up areas. Conversely, baseflow values have decreased consistently, with the average baseflow decreasing from 0.00002685 kg/m²/s (2000) to 0.00001894 kg/m²/s (2024), reflecting pressure on the aquifer system due to reduced infiltration areas. Pearson correlation analysis revealed a significant weak negative effect between NDBI and baseflow in 2000 (r = -0.219; p-value = 0), which changed to a weak positive effect in 2024 (r = 0.126; p-value = 0), indicating a shift in hydrological dynamics due to the accumulated impacts of urbanization. This finding confirms that urban sprawl has reduced groundwater recharge capacity and threatened the sustainability of clean water supplies. The study recommends the need for sustainable spatial planning policies and groundwater conservation strategies to mitigate these negative impacts.

Eleutherine bulbosa (Mill.) and Allium cepa L. (including garlic and onion peel) are medicinal plants that have long been traditionally used to treat cancer, diabetes, hypertension, infectious diseases, and inflammation. Recent scientific studies emphasize the importance of extract standardization to ensure consistent quality, safety, and efficacy. Standardization includes specific parameters—such as organoleptic identification, water- and ethanol-soluble extract values, phytochemical profiles, and determination of marker compounds—and nonspecific parameters such as moisture content, loss on drying, total ash, and acid-insoluble ash. Ethanol extract of E. bulbosa showed moisture and drying loss values below 10%, total flavonoid content of around 1.2%, and positive phytochemical tests for alkaloids, flavonoids, saponins, and quinones. Onion peel extract contains a high flavonoid content (7.84 mg QE/g) with moderate antioxidant capacity (DPPH IC₅₀ 152.65 µg/mL), while fermented garlic (black garlic) contains more than 12% polyphenols and more than 2% flavonoids, as well as a high level of S-allyl-L-cysteine (SAC) as a stable bioactive compound. The pharmacological activities of these standardized extracts include strong antioxidant effects, α-glucosidase inhibition for antidiabetic activity, induction of apoptosis and anti-angiogenesis as anticancer potential, membrane disruption and enzyme inhibition for antimicrobial activity, as well as COX/LOX modulation for anti-inflammatory effects. These activities are directly correlated with the secondary metabolite composition of each material. With their phytochemical richness and diverse biological activities, E. bulbosa and A. cepa have great potential as raw materials for standardized herbal products. Further in vivo studies and clinical trials are needed to validate their therapeutic efficacy and to support the development of evidence-based phytopharmaceuticals.

The banana chip business in Ledokombo Village, Jember Regency, is one of the sources of livelihood for the local community.

Higher education in Afghanistan faces chronic challenges stemming from decades of conflict, political instability, and underinvestment. Universities operate with limited infrastructure, outdated curricula, and overcrowded classrooms, leaving students underprepared for the demands of a competitive global labor market. The COVID-19 pandemic further exposed the fragility of the sector, as efforts to shift toward online learning were hindered by poor connectivity, unreliable electricity, and insufficient institutional readiness. This study investigates the potential of e-learning combined with artificial intelligence (AI) to address these systemic limitations and to provide a sustainable pathway for educational reform in fragile contexts. Adopting a qualitative design, the study draws on documentation analysis, field observations, and semi-structured interviews with lecturers, administrators, and students in Afghan universities. The data were analyzed thematically, focusing on infrastructure barriers, institutional capacity, and perceptions of AI-enhanced e-learning. Findings highlight that while conventional e-learning platforms expanded access during emergencies, they often lacked adaptability, personalization, and effectiveness in sustaining engagement. Participants demonstrated limited technical literacy regarding AI but expressed strong interest in its potential to improve teaching efficiency, student support, and inclusiveness. The absence of coherent policy frameworks and persistent gender and geographic inequalities emerged as critical challenges to equitable implementation. This study contributes to the state-of-the-art by extending discussions of AI in education into a fragile-state context, where assumptions of stable infrastructure and governance do not apply. It also problematizes the universality of technology adoption theories, suggesting the need for adaptations that incorporate structural and socio-cultural variables. AI-enabled e-learning can partially mitigate Afghanistan's educational infrastructure deficits when implemented alongside capacity building, inclusive design, and supportive governance frameworks. These findings hold relevance not only for Afghanistan but also for other fragile states seeking innovative, equitable, and sustainable educational solutions.

Micro, Small, and Medium Enterprises (MSMEs) play a vital role in Indonesia’s economy by contributing significantly to GDP and absorbing a large share of the workforce. However, MSMEs continue to face major challenges, including limited business legality, low human resource (HR) capacity, and difficulties in obtaining halal certification. To address these issues, the government established the Integrated Business Service Center (PLUT) as a consultation, assistance, and facilitation hub for MSME development. This study aims to analyze the implementation of the PLUT policy in supporting MSMEs, focusing on the issuance of Business Identification Numbers (NIB), capacity building for human resources, and facilitation of halal certification. A qualitative descriptive method was employed, with data collected through observations, in-depth interviews, and documentation. Data were analyzed using Miles & Huberman’s interactive model and Edwards III’s framework, which emphasizes communication, resources, disposition, and bureaucratic structure. The findings reveal that PLUT plays a crucial role in helping MSMEs secure business legality, providing training and managerial assistance, and supporting the halal certification process. Nevertheless, challenges remain, such as the limited number of consultants, bureaucratic complexity, and unequal access to digital infrastructure, which hinder the overall effectiveness of the services. The implications of this study highlight the need to strengthen PLUT’s capacity by recruiting more professional consultants, digitalizing services, and integrating with the OSS and BPJPH systems. These steps are expected to enhance the effectiveness and sustainability of PLUT’s implementation, thereby improving the competitiveness of MSMEs in the era of digital transformation.

This community service initiative aims to apply biopore infiltration hole technology as a community-based flood mitigation solution in Labuhan Ratu District, Bandar Lampung City. This area faces major problems in the form of a high risk of waterlogging caused by low soil absorption, predominance of watertight surfaces, and suboptimal drainage systems.

The freedom of expression in public is a human right guaranteed in Indonesia's legal system through Law No. 9 of 1998. The handling of public demonstrations by the Indonesian National Police, particularly the Samapta unit, plays a strategic role in maintaining order and security during protests. This study aims to analyze the role of the Samapta unit in managing public demonstrations, identify the challenges faced, and examine the implementation of human rights principles in crowd control. Using a normative legal method with a juridical normative approach, this study analyzes secondary data in the form of regulations, legal literature, and official documents, as well as primary data from Law No. 9 of 1998, Law No. 2 of 2002 concerning the Indonesian National Police, and related regulations. The results show that the role of the Samapta unit in managing public demonstrations includes three main aspects: preventive, repressive, and educational. The preventive role is carried out through coordination and security preparations as stipulated in Article 10 of Law No. 9 of 1998, the repressive role involves the dispersal of protests under certain conditions as per Article 15, and the educational role is implemented through socialization and community guidance. However, the implementation of human rights in protest security still faces challenges in aspects such as proportionality of force, non-discrimination, accountability, and public participation. The study concludes that, although it has a strong legal foundation, improvements in regulations, human resources capacity, and supervision systems are needed in handling public demonstrations.

Kampung Kelam Pagi, Dompak Village, focused on mapping the local road network as a foundation for sustainable development planning. The data collection process combined observation, interviews, and digital recording, resulting in both technical data (such as road length, width, and condition) and social data (including road naming conventions and patterns of community usage). The findings indicate notable disparities in infrastructure quality, with main roads mostly paved, while smaller neighborhood roads remain unpaved and lack adequate street lighting. This disparity in infrastructure quality highlights the need for targeted interventions to address the basic infrastructure needs of the community. In addition, the study emphasizes the importance of community involvement in the mapping process, which not only strengthened the social value of the maps but also fostered collective awareness of the importance of spatial data in village development. The discussion further underscores that local data availability is crucial for more participatory, inclusive, and community-oriented village planning, where decisions are based on accurate, locally sourced information. This study demonstrates that KKN activities do more than just provide technical data; they also help reinforce social capacity, empowering local communities to actively contribute to sustainable development efforts. Ultimately, such initiatives contribute to creating more resilient and well-informed communities that can participate in and benefit from development planning.

This study provides an in-depth analysis of the benefits of implementing a SAP-based Enterprise Resource Planning (ERP) system for end-users at PT XY, an Indonesian airport management company. A qualitative case study approach was applied through comprehensive in-depth interviews and direct observations of accounting division staff who actively utilize the SAP Financial Accounting (FI), Controlling (CO), and Materials Management (MM) modules as part of their daily operations. The findings demonstrate that SAP implementation significantly enhances work efficiency, data accuracy, and overall operational productivity across multiple business processes. The system facilitates seamless cross-departmental integration, reduces manual errors, accelerates financial reporting, and supports real-time, data-driven decision-making. Furthermore, SAP strengthens internal coordination by providing consistent, centralized, and easily accessible information to all relevant stakeholders.

Oil palm is a leading commodity that makes a major contribution to Indonesia’s economy, yet a significant productivity gap remains between actual and potential yields. A principal cause is suboptimal water management, which leads to flooding during the rainy season and drought in the dry season. This study develops a Conceptual Design (CD) for water management to map existing problems, analyse root causes, formulate improvement measures, and present a macro-level cost estimate for the study site. The research was conducted at an oil palm plantation in East Kalimantan anonymized as “PT XYZ.” The site was selected due to recurrent flooding and a recent change in ownership that limited data availability, making it well-suited for a CD-stage assessment. The objective is to identify water management issues and propose effective recommendations. A quantitative approach integrates primary data from field observations and measurements with secondary data. The analyses cover flood problem assessment, Water Management Zoning (WMZ/ZPA), rainfall analysis, hydrology, hydraulics, improvement proposals, and macro cost estimation. Results indicate that challenges are driven by swampy land conditions and inadequate channel and hydraulic structure capacity. Micro-watershed delineation using DEMNAS identified four ZPAs totalling 479–4,061 ha. Design rainfall was derived from CHIRPS satellite data using a log-normal distribution. Hydrologically, peak discharges range from 3.87–22.58 m³/s for the 2-year return period and 4.46–26.31 m³/s for the 5-year return period. Hydraulically, the proposed dimensions for rivers, outlet drains, carrier drains, and field-edge drains are 4×3×2 m to 9×7×3 m (T=2 years) and 4×3×2 m to 10×8×3 m (T=5 years), while collection and main drains are proposed at 3×2×2 m for both return periods. The total estimated investment for the 5-year design scenario is IDR 27,999,263,000.
