Abstract

This study aims to provide information about various types of urban organic waste used as raw material for liquid organic fertilizer, to collect data on the nutritional content of liquid organic fertilizer derived from various types of urban organic waste, and to recommend types of urban organic waste potential to be developed as raw material for fertilizers produced by the community. To make liquid organic fertilizer, a research project with six raw materials: vegetable waste (limited to familiar Cruciferae), fruit waste (limited to bananas and papayas), sprout waste, food waste, catfish waste, and cow blood waste. The organic matter, N, P, K, C-organic, Mg, Ca, Cu, Zn, Fe, and humic acid content of ready-made liquid fertilizer were examined across a diverse range of experimental variables. The material's structure, color, smell, temperature, and pH change during the production of liquid organic fertilizer. Liquid fertilizer from urban organic waste contains complete nutrients, including organic matter 17.98-22.15%, N 0.03-0.08%, P 0.04-0.095, K 0.31-0.825, C-organic 0.79-1.22%, Mg 2.26-4.12 ppm, Ca 2.26-11.80 ppm, Cu 0.52-0.86 ppm, Zn 2.83-3.83 ppm, Fe 2.83-3.81 ppm, and humic acid 3.85-7. POC made from fish and animal blood waste has a higher nutrient content than POC from plant waste, but it also produces odor during production, making people uninterested. Thus, it is suggested that the next research is to discover a method for producing odorless POC from fish waste and animal blood.
