ABSTRACT: This study aims to determine the effect of Aspergillus sp. on the degradation of organic wastes and its impact on soil biology and rice growth. The use of organic matter derived from various types of waste can increase soil fertility and served as ameliorant material. The addition of Aspergillus sp. in the process of composting organic materials can reduce the length of composting time, increasing the nutrient content, stimulating soil biological activity, and effecting  the growth of rice plants. The research was conducted from October 2014 untill May 2015. Composting a municipal organic waste and paddy straw using microbial agent such as Aspergillus sp. were designed by  factorial randomized.The results of composting then applied to the Tempuran rice field under the treatment of  POS + A (waste organic fertilizer + Aspergillus),  OJP + A (paddy straw organic fertilizer + Aspergillus) and without the addition of organic fertilizers. The composting process by Aspergillus sp. has affect on the declining of C / N ratio, nutrient, and moisture stability. The results of the trials on rice plants showed that organic fertilizer of the composting process waste by Aspergillus sp is  superior to other treatment on plant height and number of tillers.
