Abstract

Kompos adalah salah satu pupuk organik yang dibuat dari degradasi bahan organik. Salah satu mikroorganisme yang berperan dalam degradasi senyawa organik adalah Azotobacter. Beberapa isolat Azotobacter yang diisolasi dari lahan Eco Urban Farming ITS mampu mendegradasi karbohidrat, lipid dan protein, namun potensi Azotobacter tersebut belum diujikan apakah dapat digunakan sebagai agen composting. Penelitian bertujuan untuk mengetahui apakah konsorsium Azotobacter dapat berperan sebagai agen composting. Antar isolat A1b, A3, A6, A9 dan A10 diuji sinergisme pada media agar cawan, selanjutnya dibuat kurva pertumbuhan, penyiapan inokulan dan media kompos, pencampuran inokulan kompos, analisa maturasi kompos, perhitungan kepadatan sel, dan analisis nitrat, fosfat dan kalium tersedia. Kompos terbentuk setelah 4 minggu inkubasi dengan tekstur remah, warna coklat kehitaman dan berbau tanah. Nutrien makro N, P, K pada kompos yang tertinggi adalah nitrat 6,0 %, fosfat terlarut 4,6 %, dan kalium 1,3 %. ======================================================================================================================== Compost is one of organic fertilizer that made from organic compound degradation. One of microorganism that has role in organic compound degradation is Azotobacter. Some of Azotobacter isolated from ITS Eco Urban Farming able to degrade carbohydrate, lipid, protein, however, those Azotobacter potency still studied in individual isolat. The purpose of this reseach is to know that Azotobacter whether consortiumed can take in role as organic waste composting agent. This research carried out with consortium of Azotobacter sinergism test in plate agar medium, made growth curve, preparing of compost inoculan and compost medium, analysis of compost ripeness, counting of cell density, and analysis of nitrate, phosphate and potassium. Compost was forming after 4 weeks of incubation with crumb texture, blackish brown colour and soil smell. Macro nutrient N, P, K of compost which the highest is nitrate 6,0 %; 4,6 % phosphat; and 1,3 % potassium.
