This community service program was initiated in response to the need to strengthen collaboration between parents and schools in fostering character development and noble morals among elementary school students. The main issue addressed was the lack of structured and sustainable educational collaboration between parents and the school in supporting character-building practices. The program aimed to develop a participatory and reflective collaboration model through a systematic parenting initiative. A qualitative participatory approach based on community engagement was employed, consisting of needs assessment, joint discussion and planning, parenting program design, workshops and Focus Group Discussions (FGDs), mentoring and monitoring, as well as evaluation and reflection. The results highlight significant improvements in two-way communication between parents and teachers, increased collective awareness of the family’s strategic role in character education, and the establishment of a regular communication forum as a new social structure within the school community. Positive changes were also observed in parenting practices, including the implementation of positive discipline and empathetic communication at home aligned with school values. The emergence of local parent leaders further strengthened program sustainability. Overall, the participatory educational collaboration model proved effective in promoting social transformation and reinforcing sustainable character and moral development among students.

This research explores the development of a participatory governance model for community based waste management systems, aiming to enhance both legal compliance and public social welfare outcomes. Community based waste management (CBWM) plays a critical role in addressing environmental and health challenges, yet its success is often hindered by weak governance structures, limited community involvement, and insufficient regulatory frameworks. The study introduces a governance model that integrates local community participation into decision making processes, encouraging ownership and responsibility among residents. The primary goal is to improve compliance with environmental regulations while promoting social welfare by fostering better public health and community cohesion. A review of literature highlights key theories of participatory governance, focusing on its ability to enhance legal adherence and increase social equity. Previous studies on CBWM demonstrate the potential of community involvement in overcoming barriers to legal compliance, such as weak enforcement and fragmented governance. However, challenges like inadequate infrastructure, socio economic factors, and cultural habits still impede full participation and compliance. The study utilizes a mixed methods approach, including stakeholder analysis, participatory workshops, and regulatory compliance assessments, to evaluate the effectiveness of the model. The results show that communities involved in participatory governance exhibit higher compliance with waste management laws, improved sanitation, and healthier living conditions. Furthermore, the model fosters social capital and community empowerment, contributing to long term sustainability. In comparison to centralized waste management systems, the participatory approach is found to be more adaptable, accountable, and socially accepted. While the model presents several benefits, challenges such as infrastructure limitations and cultural barriers remain. Future research should further investigate how to address these challenges, particularly through technological integration and cross sector collaborations, to ensure the scalability and sustainability of the participatory governance model.

Participatory village development planning is often treated as a technical-administrative routine. In practice, however, planning is inseparable from political dynamics that shape who participates, whose interests prevail, and how scarce resources are allocated. This community empowerment program (PKM) in Kedung Udi Village, Trawas District, Mojokerto Regency, East Java, aimed to strengthen village governance by enhancing the capacity of village officials and community representatives to design and facilitate participatory planning while explicitly addressing the political dimension of planning. The main intervention was a workshop conducted on 22 August 2025, preceded by coordination and situational observation. Workshop modules emphasized: (1) planning as a political decision; (2) navigating dual arenas: formal (Musdes/Musrenbang and RPJMDes, RKPDes, APBDes) and informal (elite networks and gatekeeping); (3) multi-level contestation and policy alignment; and (4) practical tools, including power–interest mapping, programmatic agreements, program tagging for alignment with district planning documents, and transparency/anti elite capture mechanisms. The program resulted in improved participant literacy regarding power relations in planning and produced a follow-up action plan oriented toward institutional advocacy, continuous social control, and routine capacity reinforcement through a university and village partnership.

Automatic motorcycle spare part sales have increased along with the high use of automatic two-wheeled vehicles in the community. To support optimal sales strategies and stock management, customer purchasing pattern analysis is required. This study uses the FP-Growth algorithm to identify association patterns between automatic motorcycle spare part products that are frequently purchased together. FP-Growth was chosen because of its ability to efficiently find frequent itemsets without the need to generate candidate itemsets as in the Apriori algorithm. Transaction data is processed to form an FP-Tree which is then extracted to find relationships between items. The analysis results show combinations of products that frequently appear together, such as brake pads and engine oil, which can be used as a basis for compiling sales packages, product placement, and product recommendations. By implementing the FP-Growth algorithm, spare part stores or workshops can improve service and efficiency in sales management.

The rapid development of technology in today's era requires every profession to align with existing developments. The teaching profession is no exception. Teachers must be able to utilize technology in the learning process to create an engaging learning environment for students. To support this capability, training is essential. This community service activity aims to provide training to teachers at Bancong  Elementary School in Wonoasri District, Madiun Regency, to familiarize themselves with and be able to use the GeoGebra application. This training also aims to improve teachers' competency in utilizing digital technology as a learning medium. The GeoGebra application is an effective application for solving mathematics problems in elementary schools, particularly in geometry, particularly plane figures. The implementation method for this activity includes preparation, training, and mentoring. The training was provided in the form of workshops and hands-on practice using GeoGebra-based mathematics learning media. The activity proceeded orderly and smoothly, and the training participants understood the material well, both theoretically and in practice.

Vocational education requires a practice-based learning process supported by complete facilities so that students can master work competencies optimally. However, the condition of the Motorcycle Engineering workshop at Noemuti State Vocational High School shows that the completeness of the disc brake system practice facilities does not meet the ideal ratio standards, which affects the effectiveness of learning. This incompleteness has an impact on the low achievement of students' practical learning outcomes that have not reached the KKM. This study aims to describe the level of completeness of workshop facilities and the results of the disc brake system practice learning, and to determine whether there is a relationship between the two. The research approach uses a quantitative correlational method with a total sampling of 26 students. Data were obtained through observation, questionnaires, and documentation, then analyzed using descriptive statistics, normality tests, linearity tests, Pearson correlations, and coefficients of determination using SPSS 27. The results showed that the average completeness of workshop facilities was 42.27 and the results of practical learning were 42.81, both of which were in the good category. The Pearson correlation test produced a value of r = 0.960 with a significance of 0.000 (<0.05), indicating a very strong and significant relationship. The coefficient of determination (R² = 0.92) shows that 92% of the variation in practical learning outcomes is influenced by the completeness of workshop facilities. The more complete the workshop facilities, the higher the students' practical learning outcomes.

This study aims to analyze the influence of parental roles on fulfilling the nutritional needs of children aged 3–4 years at the Asmaul Husna Daycare (TPA) in Gorontalo. The study used a quantitative design with a cross-sectional approach and involved 60 parents as respondents. The role of parents was measured through their active involvement as educators, motivators, and facilitators in fulfilling children's nutritional needs. The results showed that 80% of children whose parents played an active role had good nutritional status based on normal weight for age and height for age indicators. Conversely, in the group of less active parents, only 36% of children achieved good nutritional status. The Chi-square test showed a significant relationship between parental roles and children's nutritional status (p < 0.05). The table data shows a clear disparity, with 32 well-nourished children coming from the active role group, while 14 children with poor nutritional status came from the passive role group. These findings emphasize the importance of monitoring dietary patterns, providing nutritious supplies, and collaboration between parents and the TPA in reducing the risk of malnutrition and stunting. Furthermore, parental involvement contributes to improved immunity, cognitive development, and the formation of long-term healthy eating habits. This study recommends holding nutrition workshops for parents as part of a sustainable TPA program.

An exhaust pipe is a tubular device used to channel combustion gases from a vehicle’s engine into the environment. In addition to this primary function, the exhaust also serves to reduce the noise level produced by engine combustion. The component of the exhaust system that significantly affects torque, brake mean effective pressure (BMEP), and noise level is the silencer. This study aims to compare the torque, BMEP, and noise levels produced by variations in the length and construction dimensions of elliptical filter designs in the silencer. The silencers used in this research have lengths of 280 mm, 300 mm, and 260 mm, with short ellipse filter diameters of 25 mm and long ellipse filter diameters of 30 mm, 40 mm, and 50 mm. The research employs an experimental quantitative method, and the data were analyzed using one-way Analysis of Variance (ANOVA). The experiment was conducted in a Mechanical Engineering workshop using a Yamaha R15 V3 155cc injection motorcycle (2021), a Super Dyno 50L dyno test, and a sound level meter, from February to April 2024. The engine speeds tested were 1500, 2500, 3500, 4500, 5500, and 6500 rpm. The results show that the variation of ellipse dimensions 25 mm × 50 mm × 260 mm produced a maximum torque of 12.77 N·m at 4500 rpm, a maximum BMEP of 1021 kPa at 4500 rpm, and a noise level of 80.3 dB. The variation 25 mm × 40 mm × 300 mm produced a maximum torque of 12.88 N·m, a BMEP of 1042 kPa, and a noise level of 75.60 dB, while the variation 25 mm × 30 mm × 280 mm produced a maximum torque of 12.67 N·m, a BMEP of 1013 kPa, and a noise level of 75.63 dB.

This study explores the practice of participatory communication and creative production implemented by the Anggrek Waste Bank along the Ciliwung River as an educational strategy for flood disaster mitigation. The research aims to understand how community-based waste management initiatives can serve as platforms for environmental learning and social empowerment. Using a qualitative approach with a case study method, this study investigates social dynamics, interaction patterns, and meanings constructed by residents through collaborative waste management and creative production activities. Data were collected through observation, in-depth interviews, and documentation. The findings reveal that participatory communication is manifested not only in formal education, counseling, or campaigns, but also in everyday interactions, creative workshops, and collective community work. Creative products such as recycled crafts, soap made from used cooking oil, and eco enzymes function as symbolic communication media that persuasively convey ecological messages while providing tangible economic benefits. These practices foster a sense of ecological responsibility, strengthen social solidarity, and enhance community resilience to flooding. This study concludes that participatory communication integrated with creative production serves as an effective model for promoting sustainable behavior and community-based flood mitigation in urban environments.

This community service initiative was designed to empower housewives in Dusun III, Desa Pematang Sijonam, by introducing ecoprint as a sustainable craft and a potential driver of micro, small, and medium enterprises (MSMEs). The activity was motivated by the limited access to alternative livelihoods in rural communities and the increasing relevance of environmentally conscious products in contemporary markets. The program adopted a descriptive qualitative design, emphasizing participatory involvement through workshops and direct practice. Participants were guided to identify tannin-rich leaves from their local environment, arrange them on pre-mordanted cotton tote bags, and apply steaming processes to transfer pigments. The outcomes revealed that participants not only acquired technical competence but also demonstrated heightened creativity and confidence, producing distinctive motifs that carried cultural and ecological values. More importantly, the training raised awareness of the economic potential of natural resources that had previously been overlooked. This activity suggests that ecoprint is not merely an artistic expression but also a practical strategy for fostering women’s economic independence, stimulating rural entrepreneurship, and strengthening sustainable development at the community level

Salem District is one of the largest coffee commodities in Brebes Regency. This significant potential has yet to provide a meaningful contribution to the income of coffee farmers, especially in Gunung Jaya village, Salem District. The low income of coffee farmers is due to the fact that they still sell their coffee products in the form of cherry. Over time, in 2018, farmers began to develop small-scale and simple coffee processing from green beans to roasted beans and coffee powder, pioneered by the SME "Lulumpang Kopi". They still use simple tools and often have to travel out of town to obtain the desired coffee powder. Lulumpang Kopi can produce 100-150 packages of coffee weighing 100 grams. Seeing this potential, the Community Partnership Empowerment team (PKM) from the University of Civilisation and UNSOED, funded by DIKTISAINTEK, is conducting community service this year 2025 using training methods, workshops, and appropriate technology grants. Thus, technology has been granted in the form of 1 Huller machine with a capacity of 150kg/batch, 1 BBM Grinding machine with a capacity of 10kg/batch, and scales. This assistance aims to enhance farmers' capabilities to achieve greater economic independence and improve their competitiveness in the market. As a result of this activity, partners were able to increase the capacity and quality of coffee farmers' production through the grant of equipment such as huller, BBM grinder, and digital scales, making the processing faster, more efficient, and yielding better coffee compared to traditional methods. In addition, the training participants also demonstrated an increase in knowledge through pre-tests and post-tests, rising from 66.5% to 77.3%, an increase of 13.8% from the 40 participants who attended.

This Community Service Program (KKN) was implemented as an effort to address the health and environmental risks associated with the use of chemical-based dishwashing soap. The program’s lack of knowledge and skills in making natural household products among women underpins the program’s implementation.
