ABSTRACT: MOL (Mikro Organisme Lokal) is the result of local material decomposition with fermentation method. MOL contains macro and micro nutrients and microbial decomposers.The smaller coffee peel that will fermented, the faster MOL can be formed. To acceleratedecomposition in MOL solution, it can be added food source of bacteria such as coconut water and brown sugar. The purpose of this study was to study the process of making MOL from coffee peel, toanalyze the content of nitrogen, phosphor, and potassium of MOL of coffee peel and todetermine the effect of fermentation time on nitrogen, phosphor, and potassium contents of MOL that resulted.
This study was conducted with 4 (four) treatments, week 1, 2, 3 and 4 and 1 factor and using 2 times replicate. The parameter of testing used for making coffee peel as local microorganism are MOL volume, nitrogen, phosphor and potassium contents.The result of study showed that the highest mol volume obtained in week 4 of 8.5 ml and the lowest in week 1 of 5 ml. They were obtained from 500 g coffee peel. Determination of nitogen, phosphorus and potassium as a macro nutrients has been conducted. The result showedthat the highest nitrogen was found to be 0,0039% in week 1, 3 and 4 and the lowest in week 2with percentage 0.034 %. Determine of phosphorus showed that the highest phosphor was obtained in week 2 wtih percentage 0.033 % and the lowest in week 4 of 0.018%, and the resultof potassium analyze, the highest obtained in week 2 of 0.035 % and the lowest in week 4 of0.014%
