Abstract

Penelitian ini menganalisis kualitas pupuk organik cair (POC) berbahan limbah kotoran kotoran ayam. Hasil analisis menunjukkan pH POC sebesar 7,43 memenuhi syarat mutu. Namun kadar airnya mencapai 94,34%, jelas melebihi batas maksimal 15%. Kandungan unsur hara dasar seperti nitrogen (0,15%), fosfor (0,05%) dan kalium (0,07%) juga berada di bawah batas minimal 3%. Singkatnya, POC yang diolah tidak memenuhi syarat mutu pupuk organik cair karena kandungan airnya tinggi dan kandungan unsur haranya rendah. Hal ini menunjukkan bahwa proses pengomposan perlu dioptimalkan untuk meningkatkan kualitas POC.

Abstract

The method used is descriptive quantitative, with primary data collected through field observations and interviews, and secondary data obtained from drone imagery and spatial planning documents. The analysis involved land classification, thematic mapping, and Nearest Neighbor Analysis (NNA). The results show that land use is dominated by sapodilla plantations (48.89%) and rice fields (33.86%), reflecting the village’s agrarian character. Regional facilities are evenly distributed, supporting educational, health, and cultural functions. The NNA indicates a clustered settlement pattern, with a Nearest Neighbor Ratio of 0.329755 and a z-score of -28.470036, signifying concentrated residential areas due to geographical factors and accessibility. These findings emphasize the importance of spatial planning in sustainable tourism village development.
