Abstract

Coal is a rock composed of organic compounds (C, H, and O), inorganic or mineral impurities, and ash content. Burning coal produces waste in fly ash and bottom ash (FABA). FABA that accumulates for a long time can cause environmental problems, such as pollution. Petrokimia Gresik Ltd. Produces FABA in large quantities, so it must be managed by external parties who have a permit to manage it. With the regulatory changes, FABA can be utilized for various products. This study aims to utilize FABA as a filler substitute for raw materials for NPK fertilizer and find the right proportion so that utilization can be carried out optimally. This study applied the Plan-Do-Check-Act (PDAC) method to achieve continuous improvement. The results show that the most optimal FABA ratio is 3:1 with the addition of ZA raw materials with a specific ratio. After analyzing the test product on NPK 15-10-12 plus fertilizer, it is found that the NPK 15-10-12 plus fertilizer using FABA as a filler complies with SNI 2083:2012 about NPK fertilizer. The effectiveness test results on paddy plants at the Experimental Garden of Petrokimia Gresik Ltd. Show that FABA as a fertilizer filler does not affect the effectiveness of NPK fertilizer. This study shows that FABA can be used as a filler substitute for raw materials for NPK fertilizer.
