Abstract

As the COVID-19 pandemic comes to an end, education has returned to normal with in-person learning. The good practices in online learning conducted during the pandemic can be maintained to support practical activities, for example, using a virtual laboratory. The limitations of laboratory facilities and the skills of educators and laboratory staff in developing practical materials have made Biology practicals minimal and monotonous. Based on discussions with partners, there is a main problem that needs to be addressed through this program, which is the limited laboratory facilities in terms of tools and materials, resulting in minimal implementation of Biology practical activities in schools. The objective of this community service is to enhance the knowledge, skills, and empowerment of Biology teachers at Muhammadiyah high schools in Yogyakarta City in conducting practicals using virtual labs. This community service method is carried out by training on Biology practical learning online using virtual labs. This program is conducted in several sessions, each lasting 200 minutes, from June to October. Each session consists of a pre-test, material delivery, Q&A discussions, and a post-test. It can be concluded that the community service activities ran smoothly and provided benefits in the form of increased knowledge and skills of participants in Biology practical learning using virtual labs.

Abstract

Household organic waste management in densely populated areas such as Tegalrejo, Yogyakarta, poses a significant challenge that impacts both environmental quality and public health. This community service program aimed to enhance the knowledge and skills of local residents—particularly members of the PRA Tegalrejo women's group—in utilizing Black Soldier Fly (BSF) larvae, or maggots, as biological agents for organic waste decomposition. The training was conducted through educational sessions, live demonstrations on maggot utilization, and interactive discussions. The results showed a 14.73% increase in participants’ understanding, based on pretest and posttest scores. Participants not only gained knowledge about the decomposition process using maggots, but also recognized the potential of maggot farming as a source of animal feed and local economic opportunity. This program demonstrates that hands-on, eco-friendly education can effectively encourage community participation in waste management while simultaneously strengthening environmental resilience and household socio-economic sustainability.

Abstract

Numerous research and related applications of fuzzy clustering are still interesting and important. In this paper, Fuzzy C-Means (FCM) and Laying Chicken Algorithm (LCA) were modified to improve local optimum of Fuzzy Clustering presented by using UCI dataset. In this study, the proposed FCMLCA performance was also compared to baseline technique based on CSO methods. The simulation results indicate that the FCMLCA method have better performance than the compared methods.
