Compost Characteristics Of Fruit Peel Waste On CV. Mahajaya Sangkara, Bali Food Industry With Effective Of Microorganism 4 (EM4) Concentration Treatment

Abstract

Fruit skin waste still contains many organic compounds that can be processed into environmentally friendly, useful, and value added products, one  of  which is  compost.   The  addition of EM4 bioactivator to composting can affect composting time faster than natural composting. This study   aims to determine the effect of EM4 concentration treatment on the characteristics of compost  from fruit skin and determine thebest compost characteristics with the addition of EM4  according  to  SNI  19-7030-2004. The experimental design used wasia Group Randomized Design with EM4 concentration as a treatment consisting of five levels namel 0%, 25%, 50%, 75%, 100%. The treatment was grouped into 3 groups based on the time of its implementation so that 15 experimental units were obtained. The obtained are analyzed-for-variance   and-if   the treatment   affects the observed variables, it is continued with the Honest Real Different Test (BNJ). The results   showed   that the addition of EM4   bioactivator had a very real effect on the temperature, pH, color, and yield of compost but had no effect on the organic matter content of compost. The best treatment that produces characteristics according  to SNI 19-7030-2004 is the addition of EM4 bioactivator by 75% which produces compost with compost temperature characteristics of  32.22±0.07^oC, compost pH 7.23±0.06, compost color L* 3.67±0.58, a* 0.33±0.58, b* 2.67±0.58, organic matter content 28.68±7.14%, and yield 51.11±0.96%.
