Abstract
Saat ini TPST Undip sudah melakukan pengomposan terhadap daun kering dengan metode konvensional, namun tetap saja pengolahan yang dilakukan belum mampu mengolah seluruh sampah organik yang ada di lokasi tersebut. Hal ini tampak dari masih adanya daun kering yang tertimbun di tiap kompartemen bak sampah. Melihat kondisi tersebut maka perlu dilakukan pencarian alternatif pengomposan metode lain yang lebih baik dan hemat untuk diterapkan. Dalam penelitian ini, sampah organik berupa daun kering yang berada di TPST Undip akan dimanfaatkan sebagai pupuk cair. Dalam pembuatan pupuk, digunakan bioaktivator berupa mikroorganisme lokal dari daun angsana (Pterocarpus indicus) yang berfungsi untuk mempercepat proses pengomposan. Penelitian ini bertujuan untuk menganalisis kualitas pupuk organik cair hasil penelitian dengan standar yang berlaku. Pengujian kualitas pupuk organik cair dilakukan dengan melihat kandungan unsur hara makro seperti C-organik, N-total, P-total, dan K-total. Selama proses komposting, dilakukan variasi frekuensi pengadukan yaitu 2 hari sekali, 4 hari sekali, dan 7 hari sekali. Pengambilan sampel dilakukan setiap 7 hari sekali selama proses komposting dan 3 hari setelah proses perendaman kompos matang. Berdasarkan SNI 19-7030-2004 dan Permentan nomor 70 tahun 2011, diketahui bahwa kualitas pupuk padat yang paling optimal didapatkan dari frekuensi pengadukan selama 4 hari sekali, sedangkan pupuk organik cair yang paling optimal didapatkan dari perendaman pupuk padat dengan frekuensi pengadukan selama 4 hari sekali. Kata kunci: Pupuk Organik, TPST Undip, Frekuensi Pengadukan [Application of Pterocarpus indicus as Local Microorganism for Liquid Compost in Mass Recovery Facility (MRF) of Universitas Diponegoro]. Currently TPST Undip already composting on dried leaves with conventional methods, but still the processing has not been able to process all the organic waste in the location. This is evident from the presence of dry leaves buried in each garbage compartment. Seeing these conditions, it is necessary to search alternative composting other methods better and more efficient to apply. In this research, organic waste in the form of dried leaves in Undip TPST will be used as liquid fertilizer. In the manufacture of fertilizer, bioactivators used in the form of local microorganisms from the leaves of angsana (Pterocarpus indicus) which serves to accelerate the composting process. This study aims to analyze the quality of liquid organic fertilizer research results with applicable standards. Testing the quality of liquid organic fertilizer is done by looking at macro nutrient content such as C-organic, N-total, P-total, and K-total. During the composting process, variations of frequency of stirring are done every 2 days, 4 days once, and 7 days. Sampling is done once every 7 days during the composting process and 3 days after immersion soaking process. Based on SNI 19-7030-2004 and Permentan number 70 of 2011, it is known that the most optimal quality of solid fertilizer is obtained from the frequency of stirring for 4 days, while the most optimal organic fertilizer is obtained from soaking of solid fertilizer with the frequency of stirring for 4 days.
