PROCESS OF MAKING LIQUID ORGANIC FERTILIZER FROM VEGETABLE JUICE WASTE WITH THE ADDITION OF LOCAL BACTERIA STARTER

Abstract

This invention concerns the manufacture of liquid organic fertilizer from vegetable juice waste through a controlled bioconversion process using a local bacterial starter bioactivator, Formulasi Unggulan Alam Domestik (FUAD). This process includes, among others, the activation stage of the FUAD starter, preparation of vegetable juice waste substrate into a carbon source component by adding 0.3% v / v molasses and 0.3% v / v KOH. The fermentation process is carried out in a closed container with a mixture composition of 13% v / v for each component B1, B2, B3, and 13% v / v ecoenzyme. 0.3% v / v molasses is added to the remaining volume with vegetable juice solvent. Fermentation is carried out with a batch system for 28 days, where fermentation conditions are maintained at a pH range of 3.5-5.5 and a temperature of 24-26°C. These specific operational conditions prevent the premature death phase of biomass, as well as maintain C / N stability, thus producing an environmentally friendly organic liquid fertilizer.
