Effectiveness of Using Organic and Liquid Fertilizers Based on Palm Oil Mill Waste

Abstract

This study aimed to assess the effectiveness of organic and liquid fertilizers derived from palm oil mill waste as an alternative to improve soil quality and control Ganoderma in PT Padasa Enam Utama plantations. This study used the DEA model, one of three model approaches, to evaluate how effectively processing palm oil waste into organic fertilizer is. The results showed that using organic fertilizers from palm oil mill waste significantly improved soil quality, as indicated by increased organic matter content and soil microorganism activity. Compared to conventional methods, this treatment also reduced the level of Ganoderma attacks by 40% and increased production yields by 15%. This success was supported by policies that focused on the ease of use of technology, employee encouragement to use it properly, and synergy of encouragement.
