Abstract

Waste is one of the environmental issues that need to be given more attention. In addition, based on the Central Statistics Agency, about 86.5% of Indonesian farmers use inorganic fertilizers. This will lead to environmental and economic problems. The viable option to solve these problems is by applying Masaro (Manajemen Sampah Zero) to enhance the abundant organic waste as organic liquid fertilizer and improve the agricultural industry's productivity. The fertilizer and feed concentrate are made by enzymatically fermenting decomposing waste using the MASARO catalyst through two fermentation stages where the macro nutrient is converted into organic acid on the first stage and continued with the amino acid decomposition on the second stage. An important indicator of the complete fermentation process of both products is pH which is required in the range 3.9 – 4.2 within four weeks. The lifetime of these products is around one year with the condition stored in a shaded location and is not exposed directly to sunlight. Therefore, the implementation of a system that can extend the lifespan of both products is necessary, so that the lifespan is not solely dependent on the storage methods of the products, which can be advantageous for both consumers and producers.
