Abstract

Latar Belakang: Biji kelor (Moringa oleifera) dan biji asam jawa (Tamarindus indica L) merupakan tanaman yang memiliki potensi sebagai biokoagulan pada proses koagulasi karena kandungan protein. Protein penyusun biji kelor dan biji asam jawa digunakan sebagai alternatif bagi penggunaan koagulan sintetik dalam memperbaiki kualitas kekeruhan air. Tujuan: Tujuan dari penelitianĀ  ini adalah diketahuinya perbedaan dosis serbuk biji kelor dan biji asam jawa terhadap penurunan kekeruhan air dengan metode jar test. Metode: Penelitian eksperimen dengan pendekatan eksperimen sungguhan dengan pola penelitian pretest posttest with control (-) group. Sampel dalam penelitian ini yaitu air sungai di kelurahan Taipa dengan cara Grab Sampling. Hasil: Persentase tertinggi penurunan kekeruhan dengan serbuk biji kelor sebesar 38,44% pada dosis 0,2 gr dan persentase tertinggi penurunan kekeruhan dengan serbuk biji asam jawa sebesar 22,83% pada dosis 0,2 gr. Hasil uji T-TestĀ  pada jenis koagulan biji kelor dengan rata-rata penurunan 118,300 NTU, sedangkan pada koagulan biji asam jawa terjadi penurunan tingkat kekeruhan dengan rata-rata 134,94 NTU. Kesimpulan: Ada perbedaan rata-rata nilai hasil setelah dilakukan uji coba pada serbuk biji kelor dan biji asam jawa.

Abstract

This community service activity is motivated by the limited understanding among Bale Village residents of the importance of sanitation around clean water sources, which can increase the risk of environment-based infectious diseases. The main goal of this activity is to improve the community's knowledge and skills in managing clean water and maintaining sanitation facilities independently. The implementation method used is participatory face-to-face training, consisting of material presentation, field demonstrations, and interactive discussions, which are then evaluated using pre-test and post-test instruments. The results show strong community enthusiasm; of 18 participants, 13 fully participated in the evaluation. Analysis results indicate a significant achievement: 92.30% (12 people) increased their knowledge scores on the criteria for clean water and sources of pollution, while the remaining 7.70% maintained their previous knowledge. In conclusion, education- and demonstration-based training is effective in enhancing the community's cognitive capacity. This success is expected to encourage the formation of independent clean water management groups to maintain environmental sanitation quality in the area

Abstract

Development is not only understood as a process of economic growth and physical infrastructure expansion, but also as a political and social process shaped by power relations among various actors within society. This article aims to analyze the structure of elite power in the dynamics of local development politics and its implications for development policy and social change in Indonesia. This study employs a qualitative approach with a descriptive analytical design through a literature review of various academic sources related to political elites, local power structures, and development politics. The analysis applies elite theory to explain how elite groups occupy dominant positions in public decision making processes and control the distribution of development resources. The findings indicate that local power structures are formed through interactions among political elites, government bureaucracy, economic actors, and community leaders who develop both formal and informal power networks, such as political patronage and patron client relationships. These conditions often lead to the phenomenon of elite capture, which can influence development policies and potentially reinforce social inequality. Therefore, more inclusive and participatory development policies are necessary to promote fair and sustainable social change in society
