Efektivitas Bioaktivator dalam Pemanfaatan Daun Eukaliptus sebagai Pupuk Kompos di HTI PT Toba Pulp Lestari Tbk

Abstract

This study aimed to evaluate the utilization of eucalyptus leaf waste from six different clones in the Industrial Plantation Forest (HTI) of PT Toba Pulp Lestari, Tbk, Habinsaran Sector, as raw material for compost fertilizer production. The research applied three treatments of decomposers EM₄, Trichoderma, M₂₁, and a control (no decomposer) with three replications and observations conducted over four weeks. Observed parameters included temperature, pH, and the C/N ratio. The results showed that the application of decomposers had a significant effect on the decomposition process and the quality of the compost. Treatments using M₂₁ and Trichoderma demonstrated higher effectiveness in accelerating composting and producing compost with better physicochemical properties compared to other treatments. Therefore, eucalyptus leaf waste from various clones has high potential to be utilized as an environmentally friendly compost material to support sustainability in the forestry and agricultural sectors.
