Abstract

Conventional organic waste composting is one of the processing of organic waste that produces fertilizer. However, the conventional composting process for organic waste lasts 1-3 months. Vermicomposting is composting that lasts a short time, and in addition, vermicomposting produces compost and worms with a high selling value. So, in this study, Musa Paradisiaca L (MPL) peel and sawdust waste were composted using the vermicomposting method into compost. The primary data in this study consisted of monitoring the C/N ratio, temperature, pH, moisture content, texture, the particle size of compost for 3 weeks of the composting process. Testing the analysis of the effect of using Lumbricus Rubellus (LR) earthworms in the composting process of MPL peel waste and sawdust by using LR earthworms. The study results showed that LR worms had no effect on temperature, pH, water content, and C/N ratio during the composting process of MPL peel waste but did affect the texture, particle size, and product of compost weight. pH, moisture content, and temperature of compos with adding LR earthworms and without LR worms was 7, less than 50%, 27-29 0C, respectively.  The C/N ratio of compost that uses LR earthworms was 28, while the C/N ratio of composting that uses LR earthworms was 33.

Abstract

The increasing of organic waste can increase environmental pollution. This can be overcome by doing aerobic composting of organic waste. This was because the method includes a simple composting method in its application. The aim of this study is to analyze the quality of compost from grass waste. In this study, composting of grass waste, banana leaf waste and cotton waste has been carried out aerobically with the waste composting method. The compost material consisted of 76% grass waste, 12% banana leaf waste and 12% cotton waste with the addition of EM4 0, 10 and 50 mL/Kg doses of compost material. Monitoring of quality compost consist of temperature, pH, moisture content, C/N ratio, phosphor and potassium. Analysis of compost quality in this study refers to SNI 19-7030-2004. The results showed that the quality of compost without the addition of EM4 was the best compost quality of all the variables in this study.
