Abstract

Pengelolaan limbah organik rumah tangga dan kebun di Kelurahan Mayasopa, Kecamatan Singkawang Timur, Kota Singkawang belum dilakukan secara optimal. Limbah sayur masih banyak dibuang secara terbuka atau dibakar, sementara potensi pemanfaatannya sebagai bahan baku pupuk organik belum dimanfaatkan secara optimal. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan pengetahuan dan keterampilan mitra dalam memanfaatkan limbah organik lokal menjadi pupuk organik cair (POC) yang dapat digunakan untuk mendukung kegiatan budidaya jagung. Mitra kegiatan adalah Kelompok Tani Tuah Talino di Kelurahan Mayasopa yang beranggotakan 10 orang. Metode pelaksanaan menggunakan pendekatan partisipatif melalui tahapan persiapan program, sosialisasi, demonstrasi dan praktik pembuatan POC, serta evaluasi pelaksanaan dan keberlanjutan program. POC dibuat menggunakan limbah sayur dan limbah kebun sebagai bahan baku, dengan penambahan EM4 dan gula merah untuk mendukung proses fermentasi. Hasil kegiatan menunjukkan bahwa mitra dapat mengikuti dan mempraktikkan tahapan pembuatan POC, mulai dari persiapan dan pencacahan bahan, pencampuran bahan, perakitan sistem fermentasi, hingga pemantauan proses. Mitra juga menunjukkan respons dan partisipasi aktif selama kegiatan, serta menilai teknologi yang diperkenalkan sesuai dengan kebutuhan dan sumber daya yang tersedia di lingkungan mereka. Kegiatan ini menunjukkan bahwa pemanfaatan limbah organik melalui teknologi sederhana dan pendekatan partisipatif dapat meningkatkan pengalaman praktis dan kapasitas teknis kelompok tani dalam mengolah limbah menjadi POC.

Abstract

Peat soils are characterized by high acidity, low base saturation, and complex nutrient dynamics, making relationships between soil chemical properties and maize productivity important to evaluate under different amendment regimes. This study aimed to explore these relationships under combinations of red mud and goat manure. The experiment was conducted for three months using peat soil from North Pontianak District, Pontianak City, Indonesia, in a 4 × 3 factorial arrangement with four red mud rates (100, 200, 300, and 400 g/polybag) and three goat manure rates (1,000, 2,000, and 3,000 g/polybag), with three replications (36 experimental units). Pearson correlation analysis explored relationships between soil pH, organic C, total N, available P, exchangeable K, Ca, Mg, and Na, cation exchange capacity, base saturation, and maize grain weight and number per cob. Correlation patterns varied among amendment combinations. Nominal associations were observed for pH, exchangeable Ca, K, and Na with grain number or weight in several combinations, while available P and cation exchange capacity were associated with grain weight in selected treatments. Overall, the observed relationships were combination-specific. Because each combination had only three replications and multiple correlations were examined, these findings should be interpreted as exploratory. Further studies with greater replication and factorial analysis are needed to confirm the observed relationships.
