Limbah kulit buah pisang, sayur kubis dan air kelapa dihasilkan cukup banyak setiap tahunnya. Disisi lain, ketiga
limbah tersebut memiliki kandungan N, P dan K yang berpotensi diolah menjadi pupuk organik cair. Penelitian ini
bertujuan untuk meningkatkan kualitas pupuk organik cair (N, P, K) dengan tambahan variasi volume urine kambing
yang difermentasikan dengan bahan baku limbah kulit buah pisang sebanyak 200 g, sayur kubis 200 g, air kelapa 100
ml dan air gula merah 120 ml dengan bioaktivator effective microorganism 4 sebanyak 14 ml. Proses fermentasi
dilakukan selama 13 hari dengan variasi volume penambahan urine kambing 300 ml, 350 ml, 400 ml, 450 ml, dan 500
ml. Hasil terbaik diperoleh pada volume 450 ml dengan kadar nitrogen sebesar 0,15%, fosfor 0,027%, dan kalium
2,89% sehingga hasil total N, P dan K yang didapatkan yaitu sebesar 3,067%. Parameter total N, P dan K yang
didapatkan telah memenuhi standar Peraturan Menteri Pertanian No. 261/KPTS/SR.310/M/4/2019.
