Banyaknya jumlah daun yang berguguran di suatu wilayah atau pemukiman merupakan potensi yang pantas diperhitungkan agar menjadi bahan yang bernilai guna, Salah satunya dengan melakukan pengomposan. Kadar air mempunyai peran yang kritis dalam rekayasa pengomposan karena dekomposisi material organik bergantung pada ketersediaan kandungan air. Kadar air menjadi kunci penting pada proses pengomposan. Tujuan dari penelitian ini adalah untuk menganalisis pengaruh kadar air terhadap pengomposan sampah organik yaitu sampah daun kering dan menentukan kadar air optimum untuk pengomposan sampah organik berupa daun kering. Penelitian ini menggunakan variasi kadar air (40%, 50%, dan 60%) dan perlakuan ukuran bahan dicacah menjadi ukuran 1cm dan menggunakan MOL tetes tebu sebagai bioaktivator.Waktu pengomposan berlangsung selama 30 hari dengan metode pengomposan secara open windrow. Berdasarkan penelitian ini kadar air yang optimal untuk proses pengomposan sampah organik daun kering adalah kadar air 60% dilihat dari Kadar C-Organik terendahnya sesbesar 27,324%, kandungan N-Total yang paling tinggi 2,441%,Rasio C/N terendahnya sebesar 11,194%, kandungan P-Total sebesar 0,211%, kandungan K-Total sebesar 1,7776% dan Nilai GI yang paling tinggi sebesar 125,58% dan kemudian hasil uji mikrobiologi menunjukan bahwa jumlah total koliform yang ada pada kompos tidak lebih dari 1000 MPN/g.Downloads
