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.
