PREPARATION OF GRANULAR POTASSIUM FERTILIZER FROM ASH OF BURNING OIL PALM EMPTY FRUIT BUNCHES

Abstract

ABSTRACT

This study aims to develop a method of making granular potassium fertilizer based on TKKS ash. The manufacturing process involves TKKS ash characterization, material processing, formulation, and granulation stages. The main parameters analyzed include potassium (K₂O) content and the effectiveness of the fertilizer in improving plant growth. The results showed that TKKS ash contains high potassium levels that can be processed into granular fertilizer with physical and chemical qualities that meet the standards. The granulation process produces fertilizer with good granule strength, Application tests on plants show a significant increase in growth parameters compared to the control. TKKS ash can be used as a raw material for the production of granular potassium fertilizers that are effective and environmentally friendly. This research provides a solution for biomass waste management and supports sustainable agricultural practices.
