Data on waste generation in 2024, nationally, in the Special Region of Yogyakarta Province, and in Bantul Regency, consistently show organic waste as the largest component (more than 50%). Based on its source, the largest waste generation (53-75%) comes from households. This community service program aims to increase the participation of households in Trayeman Hamlet, Plered Village, Plered Sub-district, Bantul, in managing their own organic waste. This program is implemented through training for local PKK members. The methods presented are biopore, the covered bucket method, the stacked bucket method, the losida method, and the gallon method so that the community can easily adjust their choices. The training continued with the creation of composting tools, inoculant solutions, and biopore infiltration holes. Obstacles faced in organic waste management are the dependence of some residents on waste collection services. Supporting factors are the high community interest in gardening, the periodic garden utilization and cleanliness competitions held by the local village, and the commitment of PKK administrators to be able to process their organic waste independently.

Waste management remains a significant challenge in Dusun Balinappang, Desa Bontoramba, Kecamatan Pallangga, Kabupaten Gowa, Makassar City. Low community awareness regarding waste sorting and proper management has led to a decline in environmental health quality. Improper waste management can result in various environmental problems, such as water, soil, and air pollution. To address this issue, a community service activity was conducted with the aim of improving public knowledge and awareness on proper waste management through the 3R approach (Reduce, Reuse, Recycle). The method used for this activity involved education through the use of posters. The posters were designed to be visually engaging and simple, making them easy for the community to understand. This visual medium effectively conveyed information about the importance of waste sorting and applying the 3R principles. Additionally, pre-tests and post-tests were used as evaluations to measure the change in participants’ knowledge before and after receiving the education. The pre-test was conducted to assess participants' initial understanding, while the post-test helped determine the extent of their knowledge improvement regarding 3R concepts and waste management practices. The results of the activity showed a significant increase in the community’s understanding of 3R principles and proper waste management techniques. The community began to demonstrate positive behavior changes, such as sorting household waste more carefully and reusing materials that could be recycled. This shift contributed positively to raising environmental awareness and improving the health of the local community. With this simple yet effective education, it is hoped that the program can continue and be expanded to other areas. This initiative will contribute to creating a cleaner, healthier, and more sustainable environment, which will have a long-term positive impact on the quality of life for the community.

Badung Market, as one of the largest traditional markets in Denpasar City, serves as a central hub of economic activity and sustains the livelihood of a substantial number of women traders. The presence of women in this sector is not only a reflection of their economic role but also of their contribution to household welfare and community development. This study aims to analyze the influence of education, income, dependents, and age on women’s decisions to work as traders in Pasar Badung. Employing a quantitative approach with an associative design, the research involved 88 respondents selected through purposive sampling from a total population of 768 female traders. Data collection methods included questionnaires, direct observation, and interviews, while data analysis utilized multiple linear regression preceded by validity, reliability, and classical assumption tests to ensure robustness. The results indicate that, simultaneously, all independent variables significantly affect women’s decision to engage in trading activities. Partially, education, dependents, and age show a significant positive effect, suggesting that higher educational attainment, greater family responsibilities, and maturity increase women’s participation in trading. In contrast, husband’s income exerts a significant negative effect, implying that higher spousal earnings reduce the economic pressure for women to seek income through market trading. These findings highlight that economic necessity, household responsibilities, and social roles remain the primary motivators for women’s active involvement in traditional market activities. The implications of this study are relevant for policymakers and local governments, particularly in designing targeted empowerment programs, skills training, and economic support mechanisms to enhance women’s entrepreneurial capacity in traditional markets. Strengthening women’s roles in this sector is crucial not only for family welfare but also for broader community resilience and local economic growth.

Asynchronous motors, commonly known as induction motors, are widely utilized due to their robustness, reliability, and efficiency in both industrial and household applications. These motors typically operate by converting electrical energy into mechanical energy through the interaction between a rotating magnetic field and the rotor. Under normal operating conditions, the rotor speed is always slightly less than the speed of the magnetic field, which is known as "slip." However, when the slip becomes negative, meaning that the rotor speed exceeds the speed of the rotating magnetic field, the motor begins to function as a generator. This condition occurs when the motor is driven above its synchronous speed by an external mechanical force, causing the rotor to generate electrical power. Using an asynchronous motor as a generator offers several notable advantages. One of the key benefits is its ability to produce a pure sine wave voltage, which is crucial for various applications that require stable and high-quality electrical power. Since these motors do not use brushes, they are free from the problems associated with brush wear and maintenance. Moreover, they do not generate radio frequency interference (RFI), making them suitable for environments sensitive to electromagnetic disturbances. The use of an asynchronous motor as a generator also provides the ability to function as a rotary phase converter. This is especially beneficial in applications where three-phase power is unavailable, but the load requires it. To facilitate this process, a capacitive voltage is required to induce excitation in the rotor. The capacitive current is supplied by an additional capacitor, which is installed in parallel with the motor output. This capacitor helps maintain the necessary phase shift and enables the motor to generate the required three-phase power.

This study aims to examine the potential of the Baduy traditional house as a realistic context in mathematics learning, particularly in the material of spatial geometry. The traditional houses of the Baduy people not only function as residences, but also hold cultural values, philosophies, and architectural structures rich in geometric elements. Using a systematic literature review (SLR) approach, this study explores various scientific sources, including journal articles, proceedings, and reference books, that discuss the relationship between spatial elements and the structure of traditional Baduy buildings. This approach was chosen so that the study obtained is comprehensive, directed, and able to illustrate the real contribution of ethnomathematics in learning. The results of the review indicate that the Baduy traditional house contains various forms of spatial geometry that can be clearly recognized, including cuboids, triangular prisms, pyramids, cubes, and cylinders. These elements are reflected in building components such as roofs, walls, floors, support pillars, and traditional household furniture. The visual and functional representation of these spatial geometry has the potential to be a contextual resource that can be utilized by teachers in the mathematics learning process, particularly through the Realistic Mathematics Education (RME) approach. By linking abstract mathematical concepts to local cultural phenomena, students not only gain a better conceptual understanding but also increase their active engagement, motivation to learn, and awareness of their own cultural identity. These findings emphasize the importance of utilizing local wisdom as an ethnomathematics approach that can provide meaningful, contextual learning rooted in the realities of students' daily lives. Through the integration of culture and education, mathematics learning can be more relevant, engaging, and support the preservation of national culture.

The presence of scattered waste in the environment has a significant impact on both environmental sustainability and human health. In Indonesia, the accumulation of waste has reached alarming levels, amounting to approximately 175,000 tons per day, or the equivalent of 64 million tons annually. Household activities are one of the main contributors, producing a wide variety of waste, including organic and non-organic materials. Poto Village is among the areas receiving particular attention regarding this issue due to the challenges it faces in waste management. Improper management of waste not only leads to air, water, and soil pollution but also increases the risk of various health problems within the community. One of the programs designed to address this problem is the 3R program, which emphasizes three main principles: reduce, recycle, and reuse. The purpose of this community service initiative is to improve public knowledge and awareness of effective waste management through the application of 3R practices. The activities were carried out in three main stages, namely preparation, education, and discussion through a question-and-answer session. The process began with a socialization activity that introduced the objectives, purposes, and sustainability aspects of waste management efforts in the village. The educational session was attended by 30 participants, consisting of housewives, farmers, and entrepreneurs, who represented key groups within the community. Furthermore, interviews with local cadres revealed that waste is collected weekly by garbage trucks, indicating the village’s commitment to environmental management. Participants responded enthusiastically throughout the educational sessions, showing a strong interest and positive reception toward the information provided. As a follow-up step, future activities could include hands-on training in waste management using available media and tools, which would allow participants to apply the concepts learned in a practical and sustainable manner.

Tawangsari Hamlet, Tejosari Village, Ngablak District, Magelang Regency, faces serious waste management challenges, reflected in the high daily waste production and the inactivity of waste banks post-COVID-19. To address this issue, the Tidar University Community Service Program (KKN) was implemented, aiming to improve environmental cleanliness through active community participation. This program also supports the achievement of the "Climate Action" goal in the Sustainable Development Goals (SDGs), which focuses on combating climate change caused by air pollution and reducing environmental pollution. The method used in this program is Participatory Action Research (PAR), which is oriented towards community empowerment by involving all stakeholders in every stage of implementation. The activity began with a series of observations to understand the condition of waste management in the community.

Home industries are small- to medium-scale production units operated within or near households, typically relying on family members or a limited local workforce, with modest capital and without large-scale industrial technology. In furniture production, the main outputs are household items such as chairs, tables, wardrobes, beds, and shelves, while by-products include sawdust and unused wood pieces. Airborne pollutants— particularly wood dust (PM₁₀ and PM₂.₅) from sanding and cutting, along with fumes from paints, solvents, and adhesives—pose significant short- and long-term health risks to workers. This community service project, in collaboration with higher education institutions, aimed to establish long-term control measures. Initial steps involved measuring PM₁₀ and PM₂.₅ concentrations and assessing workers’ blood oxygen levels. Using a descriptive approach, workplace conditions were compared before and after work. Findings revealed a correlation between dust levels and blood oxygen saturation, supporting recommendations for long-term occupational health interventions.

This study aims to analyze and describe the regulation of furniture business permits in Alak District, Manutapen Village, Kupang City, within the framework of regional and national legal provisions. Business permits are a vital aspect of legality, providing legal certainty and protection for entrepreneurs. Despite this importance, many wooden furniture businesses continue to operate without official permits. Several factors contribute to this issue, including limited knowledge of regulatory requirements, inadequate access to facilities and administrative services, and the perception among entrepreneurs that small-scale businesses do not necessarily require permits. This research adopts an empirical approach, employing semi-structured interviews with local furniture business owners who have not yet obtained permits. The findings reveal that although the government has made efforts to disseminate information and promote the importance of business permits, these initiatives have not been fully effective. Many entrepreneurs remain unaware of the legal obligations and the potential benefits that permits can provide, such as protection against legal disputes and opportunities for broader business development. The study further identifies both positive and negative impacts of the furniture industry in the local community. On the positive side, furniture businesses significantly contribute to household income, create new job opportunities, and foster creativity through innovative craftsmanship. On the negative side, they also cause environmental issues such as waste and pollution, reduce agricultural land due to the expansion of workshops, and influence lifestyle changes within the community. Based on these findings, the study concludes that the government must strengthen its role by enhancing outreach and education programs, simplifying the permit application process, and providing better support services to entrepreneurs. Additionally, active participation from business owners is crucial to ensure compliance with legal frameworks and to achieve a sustainable balance between economic growth, social welfare, and environmental preservation.

Happiness is the ultimate goal of every human aspiration. To achieve it to the fullest, humans strive to utilize all their potential. However, in practice, conflicts often arise between personal interests and the interests of others. The desire to realize all dreams becomes problematic when carried out without regard for moral values, especially in a household life built through the sacred bond of marriage. Many married couples fail to create domestic happiness due to uncontrolled ambition. This ambition, when not balanced with ethics and morals, has the potential to cause domestic conflict that results in the neglect of children's education in the family. A current widespread phenomenon shows that married couples spend more time outside the home for work reasons. This opens up opportunities for promiscuity in public spaces and reduces attention to family. If this phenomenon continues, serious problems in the family will become increasingly apparent. The rights and obligations of husband and wife are neglected, affection for children is diminished, and ultimately children feel more comfortable seeking environments outside the home. This condition becomes the entry point for negative speculation from society about married couples who are considered negligent in their household obligations. This research is expected to provide a significant contribution to understanding how families should function optimally. By placing religion as a foundation and making ethics and morals the foundation of social interactions, families can return to their true nature as the birthplace of quality generations with character, ethics, and spiritual values.  

The problem of household organic waste management, especially kitchen waste, is still an environmental challenge that has not been handled optimally. In fact, this waste has great potential to be used as environmentally friendly products. One solution that can be applied is the manufacture of eco-enzymes, which are fermented liquids from organic waste that function as a substitute for synthetic chemicals in various household and agricultural purposes. This community service activity aims to increase the awareness and skills of residents in managing organic waste through the creation of eco-enzymes as a tangible form of applying the 3R (Reduce, Reuse, Recycle) principle. The activity was carried out in Kedu Village by involving PKK women, PSRT members, the Farmer Women Group (KWT), and housewives. The methods used include counseling on the impact of household waste and the benefits of eco-enzymes, as well as direct practice of making eco-enzymes accompanied by Mrs. Faila and students of the Real Work Lecture (KKN) of Tidar University. The implementation process includes sorting kitchen waste, mixing fermentation ingredients, and monitoring yields during the incubation period. The results of the activity show that the community is able to understand the concept and techniques of making eco-enzymes well. The active participation of residents in hands-on practice reflects increased knowledge and skills in independent organic waste management. In addition, this activity encourages the formation of new sustainable habits in utilizing household waste, while reducing dependence on synthetic chemicals. Thus, this service makes a positive contribution to environmental conservation efforts and local community empowerment through educational and applicative approaches.

Pogalan Village in Pakis District, Central Java, is known as a horticultural agricultural center, with abundant vegetable production every year. However, behind this potential, this village faces a serious problem in the form of large amounts of organic waste generated from harvest residue and agricultural processing. Waste that is not managed properly has the potential to cause environmental pollution, reduce the village's aesthetics, and become a source of disease spread. To address these problems, the Tidar University Community Service Program (KKN-50) Team conducted a socialization activity for Black Soldier Fly (BSF) maggot cultivation as an environmentally friendly and economically valuable organic waste management solution. BSF maggots have been proven to decompose organic waste by up to 60% in a short time and produce useful by-products, such as dried maggots as high-protein animal feed and kasgot (used maggots) that can be used as organic fertilizer. The activity was held on July 31, 2025, at the Pogalan Village Hall, with the main participants being PKK mothers as agents of change at the household and community levels. The implementation method included initial observation of the village's potential and problems, creation of a maggot cultivation prototype, theoretical material outreach, and live demonstrations of the cultivation process. The material provided covered the BSF life cycle, cultivation techniques, selection of growing media, maggot population management, and utilization of cultivation products. The results of the activity showed high enthusiasm from participants, as reflected in the many questions and discussions during the training session, as well as their increased understanding of the benefits and techniques of maggot cultivation.

This study aims to analyze the influence of domestic wastewater management and space utilization control on pests in river-equivalent areas in Lalat Regency. The main problem raised is the low effectiveness of environmental management in the corresponding area due to the increase in domestic activities and its weakness in spatial planning. The approach used is quantitative with multiple linear regression methods. Primary data were obtained through questionnaires to 200 respondents, and secondary data were obtained through documentation studies and field observations. The results of the analysis showed that simultaneously, the five independent variables (environmental management, space availability, community participation, government supervision, and environmental infrastructure) had a significant effect on the habitat in the corresponding area (p = 0.046). Partially, only waste management (p = 0.016) and community participation (p = 0.042) had a significant effect. A determination coefficient (R²) value of 7.5% indicates that the desires of a region are also influenced by other external factors. Based on these findings, it is recommended that the need to improve the household waste management system through the construction of communal WWTP and improve the quality of household septic tanks, as well as community empowerment through the establishment of environmental forums and sustainable sanitation education to support spatial control and poverty in commensurate areas.

Economic growth in Bali Province is predominantly driven by the tourism, service, and agricultural sectors, which play a vital role in the region’s development and income generation. Over the 2014–2024 period, however, the province has experienced a fluctuating and generally declining growth trend, influenced by both internal and external economic dynamics. This study aims to examine the influence of unemployment, district minimum wage (Upah Minimum Kabupaten/Kota—UMK), and education on economic growth across the nine regencies and cities in Bali Province. Employing a quantitative approach with an associative research design, the study utilizes panel data that combines cross-section data (9 regencies/cities) and time-series data spanning 2014–2024, yielding a total of 99 observations. To ensure robust estimation, panel data regression analysis was conducted, with the Random Effect Model (REM) selected as the most appropriate method based on the results of the Hausman test. The empirical findings reveal that, simultaneously, unemployment, UMK, and education have a significant influence on regional economic growth in Bali. Partially, education exerts a positive and significant effect, indicating that improvements in educational attainment and quality can drive higher productivity and foster sustainable economic development. Conversely, UMK demonstrates a negative and significant impact, suggesting that increases in the minimum wage, while beneficial for workers’ welfare, may impose financial burdens on businesses—particularly small and medium-sized enterprises—thus potentially slowing economic activity. Similarly, unemployment has a negative and significant effect, underscoring its detrimental role in limiting economic output and household income. These results emphasize the need for policymakers to strike a balance between enhancing workforce welfare through wage regulations and ensuring that such measures do not hinder economic competitiveness. Furthermore, strengthening education policies, improving access to quality learning, and aligning educational outcomes with labor market demands are crucial for supporting long-term economic growth in Bali.

Waste management is a major challenge in sustainable development, particularly in areas with tourism potential. Paya Jeget Village, Pegasing District, Central Aceh Regency, a developing tourist destination, is addressing waste management issues that require serious attention. The increasing number of tourists visiting the village has the potential to significantly increase the volume of waste generated. Without proper management, this condition can threaten environmental sustainability and public health. Therefore, a community-based waste management approach is needed that involves the active participation of all stakeholders, from village government, community leaders, tourism operators, and the general public. The objectives of this community service activity are to increase public knowledge and awareness about sustainable waste management, develop an integrated community-based waste management system, and establish independent community waste management groups to realize a clean and healthy tourist destination. Implementation methods include outreach and education, practical training, the formation of working groups, and ongoing mentoring to ensure the program runs consistently. The community service activities carried out on June 2, 2025 have achieved the following results: 45 participants participated in the outreach activities, 90% of participants understood the importance of waste from a religious and environmental perspective, the formation of collective awareness to maintain environmental cleanliness, the formation of a waste management group consisting of 15 members, the availability of waste sorting places at three strategic points, the implementation of waste sorting activities at the household level, and the start of organic waste composting activities. In addition, this activity also succeeded in fostering a spirit of mutual cooperation in waste management and improving residents' skills in processing organic waste into compost.

This community service activity was carried out in Dahu Village, Pandeglang Regency, with the main objective of introducing and implementing biopore infiltration hole technology as a simple and environmentally friendly solution to address waterlogging and organic waste management. Biopores are small-diameter vertical holes dug into the ground and then filled with organic waste, such as dry leaves, vegetable scraps, or food scraps. This organic waste will naturally decompose through a decomposition process, producing compost that is useful for fertilizing the soil. Furthermore, the presence of biopore holes can improve the groundwater absorption capacity, thereby reducing the risk of waterlogging and minor flooding around residential areas. During the implementation, we as students not only provided theoretical explanations through socialization sessions but also actively participated directly in the field. Together with residents, we practiced making biopore holes, starting from the stages of preparing tools and materials, the process of drilling the soil, and filling the holes with organic waste. This practical activity was designed to help the community understand the steps for making biopores independently and utilizing them sustainably. The results of the activity showed an increase in community understanding and awareness of the importance of easy, affordable, and beneficial waste management. The community is beginning to realize that waste processing does not always require large costs or complicated technology. Biopore holes have been proven effective in accelerating rainwater absorption, reducing household waste volume, and improving soil fertility. Beyond the environmental impact, this activity also strengthens relationships between students and villagers through the collaboration established during the biopore construction process. Thus, this program is expected to be the first step towards a cleaner, healthier, and more sustainable village.

The ability to manage family finances is a crucial aspect in realizing household economic resilience. In practice, many housewives do not have adequate knowledge and skills in budgeting, saving, and prioritizing needs wisely. This community service activity was carried out with the aim of improving family financial literacy among housewives, especially members of the Wisma Anggrek Group, Lapandan Village. The method of implementing the activity consists of three main approaches, namely counseling on basic family financial management materials, interactive discussions to explore participants' experiences and challenges, and simulations of realistic and applicable household budget preparation. The training material covers the basic principles of financial management, saving strategies, controlling expenses, and how to prioritize needs based on the scale of urgency and financial capabilities. The results of the activity showed a significant increase in participants' understanding of the concept of family financial management. Participants are able to draw up a simple budget, recognize unnecessary expenses, and start implementing consistent saving habits. In addition, group discussions encourage the creation of spaces for sharing experiences and practical solutions among participants, which strengthens the collective spirit in building healthy financial habits. This activity has a positive impact on shaping a more planned financial mindset and behavior among housewives. It is hoped that this training will be the first step in building sustainable household economic resilience, as well as encouraging family financial independence through wise and responsible financial management.

The Clean and Healthy Living Behavior (PHBS) movement serves as a benchmark in health development efforts to improve community behavior. An individual’s health status is closely related to their behavior—the better the health-related behavior, the better the health status. This community service project aims to explore the knowledge and behavioral quality of PHBS among coastal communities in Labuan Sumbawa Village, specifically in Padak and Pasir hamlets, where all residents were the target population of the program. The implementation was carried out through a door-to-door approach, supported by undergraduate students from the Nursing and Public Health study programs. The activity was integrated with the subjects they had studied in class, namely Health Promotion, Health Education, and Community-Based Health Promotion in Coastal and Remote Areas. The expected outcomes of this community service include the application of PHBS practices in daily life, particularly in the household setting. Community members are expected to adopt handwashing practices before and after activities, especially after defecating, urinating, and before eating.

This study aims to uncover, analyze, and document the cultural values embodied in the paca or belis tradition in Manggarai community weddings in Golo Wangkung Village, Congkar District, East Manggarai Regency. The belis tradition is understood as an important element in wedding customs that symbolizes the groom's family's respect for the bride's family for their services in raising and educating their daughter until she is ready to start a household. This study uses a qualitative approach with descriptive methods, utilizing data collection techniques through participatory observation, in-depth interviews with traditional leaders, the bridal couple, and local residents, as well as documentation of the traditional procession. The results show that belis not only contains economic value through the provision of material or livestock, but is also full of social, cultural, and spiritual meaning. The main values identified include respect for parents and ancestors, the responsibility of the groom's family for the continuity of family relationships, strengthening social ties between two extended families, and a symbol of the legitimacy of marriage according to Manggarai customs. The belis tradition also functions as a mechanism to maintain harmonious relationships between families and strengthen social networks within the community. Furthermore, this tradition plays a strategic role in maintaining local cultural identity amidst modernization and changing social values. However, challenges arise when the economic value of belis experiences inflation or a shift in meaning, potentially triggering financial burdens and conflict. Therefore, preserving the belis tradition requires adjustments to its values and implementation mechanisms to maintain its relevance, without losing the essence of respect and togetherness that are at the heart of Manggarai culture. This research makes an important contribution to the documentation and preservation of cultural heritage, and serves as a reference for local governments, traditional leaders, and the community in maintaining the sustainability of the paca or belis tradition.
