Utilization of Household Organic Waste to Liquid Fertilizer

Jakarta-Garbage is a complicated problem which should be solved from upstream to downstream by involving all levels of society, industry, and government. The method that is often echoed is the processing of waste with 3R, namely Reuse, Reduce, and Recycle. The 3R method is one of the waste reduction efforts that starts from the source or upstream. This method is usually applied only to non-organic waste because it is easy to collect, sort, sell and recycle into useful items. Whereas organic waste is only transported to the landfill.

In general, most of the rubbish is organic waste or wet waste, which covers 50-60% of the total volume of waste. Therefore, the management of organic waste from its source is very helpful in minimizing waste that must be disposed of to landfill¹. Organic waste can be processed into fertilizer by the composting process. Composting technology is based on the naturally occurring organic decomposition process.

Composting or making organic fertilizer is a method for converting organic materials into simpler materials using microbial activity. Organic fertilizers are divided into 2 namely solids and liquids. Functionally, solid fertilizer needs to be mixed with the soil to make the soil looser while liquid fertilizer has a binding material so that the fertilizer solution given to the soil surface can be used directly².

Making liquid fertilizers can use simple composting methods. The composter used is in the form of a 25L gallon with an outer connecting hose which ends are immersed in a bottle filled with water to ensure the continuity of the composting process in an anaerobic atmosphere. The liquid organic fertilizer product produced has a variety of macro-nutrient content that is very dependent on the mixture of organic waste used³.

Utilization of household waste into liquid organic fertilizer can certainly be one of the efforts to reduce waste to landfill. This is in line with the government’s efforts to reduce waste. The results of these fertilizers can increase soil fertility and improve soil structure. Besides being able to be used alone, the results of the fertilizer can be sold to improve the community’s economy.
