Rotten Fruit and Cow Rumen as Local Microorganisms for Producing High-Quality Compost

Compost is an organic fertilizer that utilized for farming to reduce the use of inorganic fertilizer. utilization can improve characteristics soil and microbiology. Experiments were conducted in Environmental Health Laboratory at Surya Mitra Husada Academy Health, Kediri, Regional Kediri City, Biology Soil Brawijaya University May 2017. This study aims discover effects concentration fermentation period rotten fruit cow rumen on quality local microorganisms compost. used a factorial Randomized Block Design (RBD) 2 levels concentration, 150 grams 250 grams. These fermented different periods, 10 days 20 days. The observed parameters biological (bacterial population) chemical (pH, Carbon (C), Nitrogen (N), Phosphorous (P), Potassium (K).and carbon/nitrogen (C/N)). results show periods had significant insignificant values. largest bacterial populations cellulolytic microbes 6.65 x 106 (local microorganisms) 5 (compost). highest pH 3.11 7 temperature was 29.50C compost). (K) 7.26, 0.146, 0.067, 0.409 respectively Local microorganisms, while compost, values 8.47, 0.81, 0.36, 0.81 respectively. (C/N) ratios 86 11
