Indonesia, as a country with a pluralistic legal system, faces challenges in harmonizing customary law and state law, particularly in resolving disputes over customary land that involve traditional values of indigenous communities. This study aims to analyze how customary values are integrated with state law through a case study of court decision Number 94/Pdt.G/2022/PN Jap. The research employs a qualitative approach with content analysis techniques applied to court decision documents, supported by relevant literature reviews. The findings reveal that the court in this case not only applied positive legal norms but also considered relevant customary aspects, including the legitimacy of indigenous leaders and the recognition of communal land rights (ulayat). The panel of judges issued a decision that accommodated customary values in accordance with Article 18B paragraph (2) of the 1945 Constitution, while still adhering to the formal procedures of state law. This study identifies challenges in integrating customary law into the national legal system, such as the lack of formal regulations related to customary courts and the limited understanding of legal officers regarding local cultural contexts.

Food waste is a global issue that continues to be discussed. This is because the problem of food waste can have an impact on the environment, health and climate. Through the Sustainable Development Goals (SDGs) initiative, creating a sustainable community through food waste management is made a top priority. This article discusses the implementation of the Zero Food Waste program at SDN Ekologi Kahuripan Padjajaran using the Black Soldier Fly (BSF) maggot bioconversion approach. This community service was carried out by P3K UPI Purwakarta students who collaborated with TPS 3R Ciseureuh Purwakarta to manage food waste. This service activity is carried out through several stages which include preparation, implementation and evaluation, involving students and their parents in managing organic waste. The results of bioconversion are maggots and organic fertilizer which will be used into products with economic value. This program has succeeded in increasing environmental awareness, reducing food waste, and can create sustainable solutions in managing organic waste. It is hoped that this article can make recommendations for implementing similar methods in other areas as an environmentally friendly waste management model.

K-Means dan K-Medoids digunakan untuk menilai indikator sosial ekonomi dan kesehatan di Provinsi Jawa Timur tahun 2023 melalui metode klasterisasi. Dengan menggunakan Principal Component Analysis (PCA) untuk mereduksi dimensi variabel, penelitian ini mengelompokkan wilayah berdasarkan karakteristik sosial ekonomi dan kesehatan. Data yang dianalisis termasuk angka harapan hidup, tingkat kemiskinan, pengangguran, dan akses ke layanan kesehatan. Kebaruan penelitian ini terletak pada kombinasi unik antara PCA dan K-Medoids untuk menghasilkan klaster yang lebih akurat dan robust terhadap outlier, dibandingkan metode yang biasanya hanya menggunakan satu teknik klasterisasi atau tidak melibatkan reduksi dimensi. Hasil penelitian menunjukkan bahwa K-Medoids dengan PCA menghasilkan klaster yang lebih koheren dan terpisah daripada K-Means, terutama dalam menangani outlier. Menurut metode Elbow dan Silhouette, empat hingga lima klaster adalah pilihan terbaik. PCA meningkatkan akurasi dan efisiensi klasterisasi dengan mengurangi kompleksitas data, yang menghasilkan klaster yang lebih baik Diharapkan temuan ini akan membantu pemerintah membuat kebijakan yang lebih baik untuk mengatasi ketimpangan kesehatan dan sosial ekonomi di Jawa Timur.
