rt of the educational process, needs to be designed adaptively without neglecting the internalization of Islamic values. This study aims to analyze and describe the integration of the Quizizz platform in evaluating Islamic value-based learning at SDN Palumbonsari I, East Karawang District. The study used a qualitative approach with a case study type. Data were collected through participatory observation, in-depth interviews, and documentation, then analyzed interactively through reduction, presentation, and drawing conclusions. The results show that the integration of Islamic values was carried out systematically through three stages: evaluation planning by incorporating value indicators into learning tools, implementation of values in question design and digital feedback, and post-evaluation reflection in class. Digital features were utilized not only to display scores but also to convey moral messages that support Islamic character formation. In practice, digital evaluation functions as a cognitive measurement instrument as well as a means of habituating values. The implications of this research confirm that the use of digital platforms in evaluation can be directed as a medium for internalizing values if it is designed in a structured manner and supported by the teacher's pedagogical commitment.

tivity aims to improve literacy and practice of Islamic parenting through the Quranic Parent School program at the Merpati Early Childhood Education Post in Kutawaluya District. The program is designed to build synergy between schools and families in supporting the social-emotional and spiritual development of early childhood. The method used is a community-based participatory approach with stages of needs identification, joint action planning, parenting class implementation, and periodic reflection and evaluation. Activities are implemented through workshops, reflective discussions, simulations of Islamic parenting practices, and the establishment of a parent forum as a forum for program sustainability. The results of the activity indicate an increase in parents' understanding of the concepts of fitrah (natural nature) and adab (good manners), changes in communication patterns to be more empathetic, and consistent habits of worship and restrictions on gadgets at home. Further impacts are seen in increased discipline and emotional regulation of children at school and the formation of a Quranic family learning community. The implications of this activity confirm that strengthening Islamic parenting through the Quranic Parent School model is effective in encouraging family-based social transformation and has the potential to be replicated in other PIAUD institutions with similar characteristics.
Abstract:Village development planning that is not grounded in data can lead to poorly targeted programs, particularly for settlement-environment issues such as solid waste, sanitation, drainage, and neighborhood space quality. This…
is community service program aimed to improve residents’ literacy in data-based planning and strengthen meaningful participation in formulating settlement-environment program proposals. The activity was conducted in Kalijaga Village, Aikmel Subdistrict, East Lombok Regency, on 17 November 2025 as a special village deliberation meeting (Musyawarah Desa Khusus; Musdesus) involving 75 participants representing village stakeholders, including youth and community organizations (Karang Taruna and the Village Community Resilience Institution/Lembaga Ketahanan Masyarakat Desa; LKMD). A participatory education approach was applied through short lectures, focused discussions, and hands-on proposal drafting using simple minimum data and a standard structure (problem–location–target group–indicators–resource needs). Evaluation was descriptive using facilitator field notes and a proposal-completeness rubric. Of 49 written proposals collected (N=49), 40 (81.6%) met all minimum elements, while 9 (18.4%) were incomplete. The results indicate a shift from general complaints toward more structured proposals with clearer locations, target groups, and basic indicators. Data-based village planning education is a low-cost intervention to improve the quality of community participation outputs and enhance the readiness of proposals for subsequent village planning processes..
Abstract:Cocoa is a strategic commodity in Southeast Aceh Regency, but farmer productivity and income remain low due to limited implementation of Good Agricultural Practices (GAP) and poor access to price information. This community…
ity service activity aims to improve farmers' capacity through an integrated approach that combines improving cocoa cultivation knowledge, strengthening the implementation of GAP, and utilizing real-time cocoa price information applications. The activity was carried out in December 2025 through stages of socialization, technical training, field demonstrations, introduction to price applications, as well as mentoring and evaluation. The results of the activity showed an increase in farmers' knowledge levels from low to medium to high, especially in terms of price information. Initial improvements in GAP adoption were reflected in pruning, fertilization, garden sanitation, pest control, and harvesting and post-harvesting practices that were more in line with standards. Access to price information shifted from dependence on middlemen to the use of applications and market comparisons, which increased farmers' independence in determining the time of sale. The price range difference between farmers and market references confirms that limited information weakens farmers' bargaining position. Overall, the integrated approach has proven relevant in improving farming efficiency and strengthening the basis for increasing cocoa farmers' income, although the sustainability of the impact requires continued assistance and strengthening of farmer institutions.

Abstract:ABSTRACT The objective of community partnership program cluster 2 (CPP-C2) is to provide micro and small-scale layer chicken farmers in Tomohon city with business management procedures based on “biosecurity”. Problems faced…
blems faced by partners, both farm owners and farm workers: 1) lack of knowledge and understanding of the concept and application of biosecurity 2) lack of sanitation application, which increases the risk of diseases emerging and spreading 3) not yet aware that the use of open house system, unfenced farms and no procedures for entering the farm area, are not in accordance with the principles of biosecurity system. The activity was carried out in stages: survey, socialization on the concept and implementation of the 3-zone biosecurity system, provision of disinfectants and examples of regulation for laying hen farming as well as evaluation. The evaluation results show that during the extension activity, out of 8 participants only 2 were actively asking questions, and it turned out they were the farm owners, while the farm workers were passive. It was found after the outreach activity, that the farm owners or farm workers who were partners had not been implemented the 3-zone biosecurity system, therefore outreach activities regarding biosecurity on poultry farm still need to be provided again to them, so that the concept and application of biosecurity will be truly understood and they would be willing to do so. However, at least 2 farms have prepared signboards with rules for entering the farm area. The occurrence of outbreaks and pandemics should be a lesson-learned that biosecurity measures are highly relevant to the saying “it is better to prevent than cure”. If, chicken remain healthy, they produce high-quality and safe products, and so, farmers can minimize health costs and maximize profits, even enabling farms owner to expand their businesses scale. In conclusion, this activity has not been given a significant impact on partner’s farm management because all partners have not been implemented the 3-zone biosecurity system, and it would be better if, all farm owners as decision makers to participate in this kind of activity, as well as the need for synergy between relevant agencies in the livestock sector in Tomohon city and academics with poultry farming business practitioners in an effort to maintain livestock health, poultry communities and maintain food security.
