Abstract: Padukuhan Karangrejek, Karangtengah, Imogiri, Bantul, is a sloping area prone to landslides due to high rainfall, soil erosion, and vegetation degradation. Landslides often threaten the safety of residents, damage infrastructure, and disrupt the sustainability of the local environment and economy. This study aims to apply bioengineering through the planting of slope-stabilizing plants to improve slope resistance to landslides using an environmentally friendly and sustainable nature-based approach. The methods included surveying planting locations, preparing planting holes, making tree marker boards, and participatory phased planting with the community. The types of plants used were Munggur, Soursop, Jackfruit, and Teak, which have strong root systems to strengthen soil structure and reduce erosion. The results showed an increase in soil cohesion through root penetration, a reduction in rainwater runoff, suppression of erosion, and a decrease in the risk of subsequent landslides. The positive impacts included increased soil water retention, improved soil fertility, community empowerment in disaster management, and economic added value from fruit and timber crops. Conclusion The application of bioengineering with Munggur, Soursop, Jackfruit, and Teak trees is an effective, inexpensive, and sustainable solution for landslide mitigation in Karangrejek Hamlet. Recommendations include monitoring growth periodically, expanding planting to other slopes, and integrating the program into the village's disaster resilience plan for long-term sustainability.

Three-phase induction motors are essential components in industrial cooling systems that require reliable overcurrent protection to maintain operational continuity and prevent equipment damage. In the Cooling Tower Pump panel at PT DongJin Indonesia, a limitation was identified where the terminal of the Electronic Overcurrent Relay (EOCR) could not accommodate the 50 mm² power cable, preventing direct current measurement. This study aims to analyze the effectiveness of integrating a 200:5 A Current Transformer (CT) with the EOCR as an adaptive protection solution that is both safe and efficient. The research employs a case study approach through field observation, motor current measurement using a Fluke 303 Clamp Meter, and descriptive analysis of the recorded data. The results indicate that the three motors operate under stable load conditions, with current values ranging from 236.7 A to 275.7 A, while the secondary current detected by the EOCR ranges from 3.7 A to 3.9 A, consistent with the CT transformation ratio. During the starting phase, the current surged to 600.4 A without causing false tripping, demonstrating that the EOCR effectively distinguishes temporary inrush current from actual fault conditions. Therefore, the integration of CT–EOCR is proven to enhance measurement safety, maintain motor operational stability, and support efficient system maintenance in industrial environments.

However, several challenges remain, including limited capital, lack of processing technology skills, and competition with chemical-based products. The recommended solutions include capacity building through training and mentoring, better access to funding, and strengthening digital marketing strategies. Therefore, the development of mosquito repellent products from lemongrass by MSMEs not only contributes to the community’s economic growth but also provides an environmentally friendly alternative beneficial for public health.

Seren Village has abundant organic waste potential, particularly banana peel waste generated from banana-processing MSME activities and wood ash resulting from household firewood combustion. To date, this waste has not been optimally utilized and is often discarded, thereby posing potential environmental problems. This study aims to process banana peel waste and wood ash into an innovative, environmentally friendly shoe polish made from natural materials, while also enhancing the economic value and welfare of the community. The research employed a descriptive qualitative method with a case study approach. Data were collected through observation, interviews, and documentation involving the women’s Family Welfare Empowerment Group (PKK) of Seren Village as the target participants. The shoe polish production process includes drying and grinding banana peels, mixing them with a wood ash solution that functions as a natural coloring agent, adding supporting materials, and heating the mixture until a ready-to-use shoe polish is obtained. The results indicate that the shoe polish produced from banana peels and wood ash has a solid texture, is slightly coarse, non-glossy, and has a relatively fast drying time of approximately one minute. In addition, the product shows good resistance to water splashes and does not damage the surface of shoes. The use of natural ingredients makes this shoe polish safer for health. The utilization of this waste has the potential to support MSME development, reduce environmental pollution, and sustainably improve the welfare of the Seren Village community.

Digital transformation has become a critical lever for modernizing maritime logistics, particularly in archipelagic nations where supply chain fragmentation poses persistent operational challenges. This study examines the integration of Internet of Things (IoT) and blockchain technologies as dual mechanisms for enhancing supply chain transparency within Indonesian domestic shipping networks. Employing a qualitative research design supported by thematic analysis, the study engaged maritime logistics experts, port operators, and shipping company representatives as primary respondents. Findings reveal that IoT-blockchain integration significantly improves real-time cargo visibility, reduces documentation fraud, and strengthens regulatory compliance across multi-port supply chains. The research further demonstrates that digital transformation in maritime logistics is not merely a technological upgrade but a governance and institutional reform imperative, particularly given Indonesia's strategic maritime position. Results indicate an overall high performance score across transparency, efficiency, and security indicators, affirming the readiness of key stakeholders to adopt integrated digital solutions. The study contributes a replicable framework for digital maritime logistics governance applicable to archipelagic developing economies seeking sustainable supply chain advancement.

The goal of this thesis is to increase awareness and give victims a better understanding of the causes of bullying and coping mechanisms by analysing the causes, effects, and efficacy of current anti-bullying interventions at Cendekia Harapan School in Jimbaran, Bali. To strengthen anti-bullying initiatives, it also assesses current solutions and makes culturally appropriate suggestions. Students completed open-ended surveys as part of a qualitative research design to learn more about their individual experiences, opinions, and the success of ongoing programs. To find patterns in bullying behaviours and their impacts, thematic analysis was used. The results showed that bullying is frequently caused by insecurity, a desire for power, and a need to fit in. Bullying victims often experience emotional distress, mental health conditions like anxiety and depression, and academic decline. According to the study, bullying can be influenced by the school environment. While students believe that current initiatives are effective, they also recommend additional interventions like workshops that foster empathy and greater parental involvement. These findings provide useful recommendations for improving school-based anti-bullying initiatives and corroborate theories put forth by Olweus and Adler.

The development of rural economies based on locally superior commodities is an integral part of inclusive and sustainable development strategies. Sumberdem located in Wonosari Subdistrict, Malang Regency, possesses significant potential for the development of coffee-based ecotourism. However, this potential remains largely underutilized due to several structural and institutional constraints. Key challenges include inadequate supporting infrastructure, limited capacity of local human resources, and the absence of downstream processing for coffee products. This community engagement program implemented an adaptive approach known as the Lumintu model, rooted in the Participatory Rural Appraisal (PRA) framework. Field assessments revealed critical limitations such as poor road access to plantation areas, insufficient agricultural irrigation, and weak digital connectivity. Moreover, the capacity of village institutions—such as the Village-Owned Enterprises (BUMDesa) and coffee farmer groups—remained low, resulting in local coffee products with limited added value. The initial implementation of the program has shown promising results, particularly in strengthening institutional capacity through training on tourism business management and high–value coffee processing. Furthermore, product diversification through the development of coffee-based agrotourism and digital marketing innovations has been successfully introduced. Overall, this community engagement initiative has provided a concrete solution to rural development challenges in Sumberdem Village. Moving forward, the village is expected to strengthen its position as a sustainable coffee ecotourism destination and improve the long-term economic well-being of its residents. The proposed development model also holds the potential for adaptation and replication in other rural areas with similar characteristics, thereby supporting the broader achievement of the Sustainable Development Goals (SDGs).

Advances in digital technology have had a significant impact on the lives of elementary school students, particularly regarding the use of electronic devices. Children often use these devices for learning, entertainment, watching videos, and accessing social media. Proper use of these devices can have positive effects, such as improving students’ access to information, fostering creativity, and boosting their enthusiasm for learning. However, if used excessively, electronic devices can lead to negative effects such as dependency, declining academic performance, psychological issues, poor social interaction skills, and a reduction in children’s physical activity. This study aims to examine the impact of electronic device use on elementary school students and analyze the role of guidance and counseling services in addressing these issues. In this study, the method employed was a literature review utilizing various sources from scientific journals and relevant books regarding the use of electronic devices and guidance and counseling services in elementary schools. The findings indicate that guidance and counseling services play a crucial role in helping students manage their use of electronic devices through preventive, curative, and developmental approaches. Guidance and counseling teachers can offer group guidance, individual counseling, and classroom-based services, as well as utilize digital technology in the delivery of counseling services. Furthermore, collaboration between schools and parents is crucial in monitoring children’s use of electronic devices. Therefore, digital-based guidance and counseling services can serve as an effective solution in helping students use electronic devices in a healthy, wise, and responsible manner.

The practice of adoption (tabanni) is a social reality that is culturally embedded in Indonesian Muslim society, but often experiences normative clashes with classical Islamic inheritance law which requires blood relations (nasab) as the basis for inheritance. This gap has the potential to trigger distributive injustice for adopted children who do not have inheritance rights despite having emotional closeness and economic dependence. This study aims to analyze the legal status of adopted children and the application of Article 209 of the Compilation of Islamic Law (KHI) concerning Mandatory Wills as a legal solution. This study is a normative legal research with library research methods that use a statutory approach and a conceptual approach. The analysis was conducted descriptively qualitatively using analytical tools of Maqashid Syariah theory, Maslahah Mursalah, and the theory of Mandatory Wills. The results of the study indicate that Article 209 of the KHI reconstructs the status of adopted children not as Heirs, but as Recipients of Wills, in order to maintain the purity of lineage according to sharia principles. This article transforms the paradigm of wills from voluntary (tabarru’) to mandatory (ijbari) through an ex-officio state mechanism. Philosophically, this application is validated by the principle of Maslahah Mursalah to fill the legal vacuum for the protection of children (hifz al-nafs) and Maqashid Syariah in realizing justice in the distribution of assets (hifz al-mal) without violating the principle of descent (hifz al-nasl). The limitation of a mandatory will of a maximum of one-third (1/3) functions as an instrument of distributive justice (al-’adalah) and a safety valve to protect the rights of lineage heirs (dzawil furud) from being oppressed. It is concluded that Article 209 of the KHI is a form of social engineering and ijtihad typical of Nusantara Islam that applies a middle path (wasatiyah) in family law.

Litigation has long been regarded as the primary method of dispute resolution. However, in practice, it is often criticized for its lengthy procedures, high costs, and adversarial (win–lose) nature, which limit its effectiveness in restoring relationships and accommodating the parties’ interests. As a result, non-litigation alternatives such as negotiation, mediation, and arbitration are increasingly considered more flexible, faster, and better able to preserve relationships between the parties. This study examines the effectiveness of dispute resolution methods: litigation, mediation, arbitration, and negotiation, by focusing on key aspects, including procedure, cost, time, flexibility, and legal certainty. This approach is used to identify the characteristics of each method in responding to various types of disputes, particularly within complex business and civil law contexts. The findings indicate that no single method can be considered universally effective for all types of disputes. Litigation remains relevant as an ultimum remedium in the enforcement of formal law, especially when binding and enforceable decisions are required. Meanwhile, negotiation serves as the simplest, fastest, and most cost-efficient initial option, allowing parties greater autonomy in reaching agreements. Mediation has proven effective in producing collaborative, consensus-based solutions that support long-term relationships, while arbitration offers a balance between efficiency and legal certainty through final and confidential decisions.

The R05 Community Service Program (KKN), Subgroup 1 in Kalikatir Village, Gondang District, Mojokerto Regency, aims to implement hydram pump technology as an environmentally friendly and energy-efficient irrigation solution. This technology is designed to meet the water needs of 100 hectares of banana plantations, especially during the dry season. The implementation method includes initial surveys, design, manufacture, installation, and testing of the hydram pump, involving the participation of Kalikatir villagers. The results show that the pump is capable of lifting water to a height of 30 meters with 70% efficiency, although it has not yet reached the daily target. This technology has been proven to reduce operational costs and increase agricultural productivity. It is hoped that in the future, this technology can be further developed to improve its efficiency and sustainability.

This study aims to analyze the determinants of policy lapse behavior among policyholders of PT Prudential Life Assurance in Medan. The research employs a descriptive qualitative approach involving 10 policyholders selected purposively based on their experience of policy lapse. Data were collected through in-depth interviews, observations, and documentation, and analyzed using data reduction, data presentation, and conclusion drawing techniques. The findings indicate that policy lapse is a multidimensional phenomenon influenced by interconnected economic, cognitive, and service-related factors. Household financial pressures, declining income, and increasing living expenses encourage policyholders to prioritize essential needs over insurance premium payments. In addition, limited financial literacy leads many policyholders to perceive insurance primarily as a financial burden rather than a long-term risk management instrument. Dissatisfaction with agent services, including inadequate communication, insufficient policy education, and weak after-sales assistance, further reduces policyholders’ commitment to maintaining active coverage. The study also finds that policyholders frequently regard insurance as a last-resort liquidity source, supporting the Emergency Fund Hypothesis, whereby policies are surrendered or allowed to lapse during periods of financial distress to meet urgent household needs. This research concludes that policy lapse is often a pragmatic response to economic uncertainty rather than merely a consequence of unwillingness to pay premiums. Therefore, improving product transparency, strengthening financial literacy, and enhancing the role of insurance agents as proactive, solution-oriented financial advisors are essential strategies for increasing long-term policy persistence and customer retention.

Waste management issues in boarding school environments represent one of the environmental challenges that require educational, participatory, and sustainable solutions. Students’ activities that take place continuously throughout the day within the school and dormitory areas contribute to the increasing generation of domestic waste, including plastic waste, disposable sanitary pads, cosmetic packaging, and other household waste. On the other hand, waste management practices in schools are still predominantly conducted manually, resulting in less effective and poorly organized environmental management systems. This community service program aimed to support sustainable environmental education through the digitalization of the school waste bank assistance program at SMA Putri Luqman Al-Hakim. The program was implemented using participatory and educational approaches consisting of observation and problem identification, socialization and education, implementation of waste bank digitalization, as well as monitoring and evaluation stages. The activities included waste segregation education, the application of the 3R concept (reduce, reuse, recycle), and assistance in using a digital-based waste deposit recording system through online spreadsheets and simple applications. The results demonstrated an improvement in students’ understanding and participation in school waste management activities. Furthermore, the implementation of the digital system contributed to a more organized, transparent, and easily monitored waste bank administration process. The program also played a role in fostering environmentally responsible behavior and improving students’ digital literacy. Therefore, the digitalization of school waste banks can serve as an alternative strategy to support environmental education and sustainable school environmental management.

Pigs hold significant economic, social, and religious value in the Wamena community, becoming an integral part of their customary law. However, the Muslim minority in Wamena faces unique challenges, as they struggle to balance local traditions with Islamic law. This study aims to explore the interpretation of Ahkām verses among minority Muslims in Wamena and analyze the Islamic laws regarding the sale and purchase of pigs in this context. The research is qualitative, combining observations and literature studies. It examines the issues surrounding pig transactions in Wamena and reviews relevant Ahkām verses along with scholarly opinions. The study identifies four patterns in the religious understanding of Wamena Muslims: traditional religion, formal religion, rational religion, and a precursor method that combines traditional practices with reasoning and revelation. Tafsir Ahkām offers solutions for minority Muslims by considering the systematic approach to Ahkām verses, hadith, and the school of jurisprudence. Despite the prohibition of pigs in the Qur’an and hadith, Wamena Muslims’ engagement in pig transactions can be analyzed using fiqh aqalliyyāt principles, such as ijtihād tarjīhi and ijtihād ibdā’i, with an emphasis on gradual implementation and accommodating Islamic and customary laws for minority Muslims in Wamena.

Digital transformation in archive management is an urgent need for public service institutions, including regional hospitals.

The system is designed to improve the efficiency and effectiveness of archive management, accelerate access to information, and minimize the risk of loss or damage to physical documents. The development stages include needs analysis, system design, implementation, testing with the Black Box method, and maintenance. The results of the implementation show that the system is able to accommodate archiving needs well, improve administrative performance, and support the digitalization of hospital services as a whole. The study also emphasizes the importance of training for users so that the system can be operated optimally, as well as integration with existing hospital information systems to ensure sustainability. Thus, this web-based digital filing system is expected to be a strategic solution in supporting more modern, transparent, and accountable public services in the regional hospital environment.

In the digital era and free market, technology is growing rapidly. Consumers and businesses are now more inclined to use digital transactions rather than face-to-face cash transactions. This study aims to find solutions and receive feedback related to the implementation of the Consumer Protection Law in the Digital Era and Free Market. The method used in this activity is through counseling and discussion. From the results of this activity, it was concluded that Law No. 8 of 1999 concerning Consumer Protection needs to be updated immediately as it is no longer relevant to the current digital technology, which has advanced far and is different from the conditions in 1999 when the consumer protection law was issued. The results of this activity indicate that the Consumer Protection Law No. 8 of 1999 requires comprehensive updates to accommodate the development of digital transactions, personal data protection, and consumer rights in cyberspace. Furthermore, the importance of educating consumers about their rights in digital transactions is also a key focus, so that the public can avoid losses resulting from unsafe online transactions.
