Abstract

This study aims to apply the K-Means algorithm to cluster students based on their mathematics grades at Madrasah Tsanawiyah Islamiyyah Yami Waled. By categorizing students into clusters of low, medium, and high academic achievement, the institution can develop more effective and targeted learning strategies. The data consisted of semester mathematics grades from 112 students, analyzed using the K-Means clustering algorithm. Clusters were evaluated using the Davies-Bouldin Index (DBI), with results showing three distinct clusters: Cluster 0 (low achievers, 54 students), Cluster 1 (medium achievers, 37 students), and Cluster 2 (high achievers, 21 students). The DBI score of 0.893 indicates good clustering quality, providing valuable insights for personalized learning approaches.

Abstract

The issue of household waste management remains a significant challenge in society, including in Bongkok Village, Paseh Subdistrict, Sumedang Regency. Low awareness and limited utilization of waste often lead to environmental pollution and potential health problems. Through the Community Service Program Kuliah Kerja Nyata (KKN) of Universitas Muhammadiyah Bandung, Group 27 conducted educational and training activities for the community, especially housewives, on managing used cooking oil (minyak jelantah) and organic waste by applying the 3R concept (reduce, reuse, recycle). The innovation introduced includes processing household waste into aromatherapy candles made from used cooking oil, providing economic value while being environmentally friendly. Meanwhile, organic waste is processed into compost and liquid fertilizer using the stacked bucket method (ember tumpuk). This program aims to improve the community’s knowledge, skills, and awareness of responsible waste management while offering practical solutions to reduce environmental pollution. The results show an increase in community enthusiasm and understanding of the importance of proper household waste management. It is expected that, through this activity, the community will become more independent and actively contribute to creating a cleaner, healthier, and more productive environment.
