KUALITAS VERMICOMPOST DARI SLUDGE BIOGAS SAPI PERAH DAN RARAPEN PADA BERBAGAI PADAT TEBAR Lumbricus rubellus

Penelitian ini bertujuan untuk mengetahui kualitas vermicompost sludge biogas sapi perah dan rarapen pada masing-masing padat tebar Lumbricus rubellus yang berbeda. Penelitian dilaksanakan dengan menggunakan metode Rancangan Acak Lengkap (RAL). Perlakuan yang diberikan adalah tiga perlakuan yakni : T1 (11g/l), T2(13g/l), T3 (15g/l) dengan masing-masing 6 kali ulangan. Proses dekomposisi awal dilakukan selama 15 hari dilanjutkan dengan vermicomposting selama 15 hari. Hasil penelitian menunjukkan bahwa : (1) kandungan N total pada setiap perlakuan berbeda nyata, dengan kandungan N total masing-masing perlakuan berturut-turut 3,17% (T1), 3,84% (T2), dan 2,64% (T3). (2) kandungan P205 antar perlakuan tidak menunjukkan perbedaan nyata, dengan kandungan P2O5 masing-masing perlakuan berturut-turut 1,92 % (T1), 1,95% (T2), dan 1,90% (T3). (3) kandungan K2O antar perlakuan menunjukkan perbedaan nyata, dengan kandungan K2O masing-masing perlakuan berturut-turut 12,67% (T1), 13,04 % (T2), dan 13,34% (T3).

This study aims to determine the quality of dairy cattle processing biogas sludge and rarapen vermicompost on various stocking density of Lumbricus rubellus. The experiment was conducted using The method used an experimental method using completely randomized design (CRD), with three treatments stocking density of Lumbricus rubellus Ti (11g /L), T2 (13g /L), T3 (15g /L) with six replications. The decomposition process was conducted for 15 days followed by vermicomposting for 15 days. The results showed that: (1) total N content in each treatment was significantly different, with a total N content of each treatment respectively 3.17% (T1), 3.84% (T2), and 2.64% (T3). (2) P2O5 content between treatments was not significantly different, with a P2O5 content of each treatment respectively 1.92% (T1), 1.95% (T2), and 1.90% (T3). (3) the content of K2O significantly different between treatments, with a K2O content of each treatment respectively 12.67% (T1), 13.04% (T2), and 13.34% (T3).
