Local decomposer increase composting rate and produce quality rice straw compost

Abstract

This study at aiming to examine the ability of Balinese local decomposers in composting rice straw. Another goal is to examine the composting rate and quality of compost in enumeration rice straw that is not enumerated. The study used 2 combinations of local decomposers and comparative decomposers. The local decomposer 1 combination consists of Paenibacillus polimyxa, Pseudomonas flourescens, and Trichoderma hazianum. The combination of local decomposers 2 consists of Pseudomonas flourescens, Trichoderma hazianum, and Aspergilus niger. Comparative decomposers are commercial decomposers consists of Azospirillum, Aspergillus, Actinomycetes, Lactobacillus, Pseudomonas, and yeast. The study was conducted in Tangkas Village, Klungkung on June 17 up to July 23, 2017. The study used a Randomized Block Design (RBD) with 3 (three) replications. Composting is conducted for 35 days and compost reversal is conducted every 7 days. The results showed that the addition of local decomposer 1 was able to provide a C/N ratio of up to 13.78, local decomposers 2 to 14.80 and this result was not significantly different from the comparison decomposition C/N ratio which reached 15.31.
