Abstract
As the human population increases, the more waste is generated. Domestic waste is waste generated from the rest of household activities, restaurants, offices, etc. is not dangerous, although it is not dangerous, proper handling is needed so as not to cause new problems. One of the organic waste managements that applies the 3R (Reuse, Reduce, Recycle) principle is the manufacture of liquid organic fertilizer which is carried out using the working principle of fermentation. The organic waste sample used in this study was stale rice that had not been overgrown with mushrooms. The research method used in this research is literature study and qualitative research. This study aims to determine the proper use of domestic waste using the 3R principle and to analyze qualitatively the indicators of successful fermentation of liquid organic fertilizer. Broadly speaking, this research is divided into 3 stages, namely the preparation stage, the fermentation stage and the storage stage. The length of time it takes to make this liquid organic fertilizer is 13 days. The results showed that the fermentation carried out was successfully characterized by liquid organic fertilizer which was cloudy white in color and smelled like tapai.
