Abstract
Compost can be used to reduce waste, it formed naturally, but it will take a long time, around 6-12 months. Bioactivators accelerate composting process; one of them is a solution of LMO (Local Microorganism) coconut pulp. The purpose of this study to determine the effectiveness of LMO coconut pulp for the composting time. The method in this research is quasi-experimental. This study consists of 3 treatments with 5 replications. Treatment 1 composting with the addition of LMO coconut pulp 50,000 ppm; treatment 2 composting with the addition of LMO coconut pulp 100,000 ppm; treatment 3 composting with the addition of LMO coconut pulp 200,000 ppm. The materials used in this study are vegetables and sawdust and the composting process carried out aerobically. From the observations, the average time to compile with LMO coconut pulp 50,000 ppm is 21.00 (21 days), 100,000 ppm 18.60 (19 days) and 200,000 ppm 18.20 (18 days). Based on the ANOVA test, the p value is 0.0001 (p <0.05) which means that H0 rejected, that there is a significant difference in composting time using LMO coconut pulp 50,000 ppm, 100,000 ppm, and 200,000 ppm. The most significant difference is between compost with LMO coconut pulp 50,000 ppm and compost with LMO coconut pulp 200,000 ppm. It is recommended for the further researchers using other types of waste, and test the quality of compost produced especially C/N compost. The community can use coconut pulp as a bioactivator in accelerating the composting process.

Highlights
Based on data from the Ministry of Environment and Forestry, Indonesia produced up to 65 million tons of waste in 2016, and increased by 1 million tons from the previous year
First treatment composting with the addition of MOL coconut pulp 50,000 ppm, second treatment composting with the addition of MOL coconut pulp 100,000 ppm, third treatment composting with the addition of MOL coconut pulp 200,000 ppm
Based on the graph, composting with MOL of Coconut Pulp 50,000 ppm has the highest temperature on the 9th day with an average of 34.74oC
Summary
Based on data from the Ministry of Environment and Forestry, Indonesia produced up to 65 million tons of waste in 2016, and increased by 1 million tons from the previous year. Garbage is still a problem that worries the community and is one of the causes of environmental damage (Hamidah, 2018). Garbage is still a classic problem for every country, including Indonesia. Along with population growth and technological development, the type and volume of waste has increases. Compost produced from organic waste can be used to fertilize plants because compost has been proven to help improve soil fertility and increase crop production. In addition to its own use, the compost produced can be sold because the demand on the market is quite high (Suwahyono, 2015)
