Pengaruh Kompos Kulit Kopi dan Ze Olit Terhadap Sifat Fisik Tanah Inceptisol Serta Produksi Tanaman Kacang Tanah (Arachis Hypogaea L.)

Abstract

Discarded coffee peel waste can be used as compost while zeolite plays a role in fix soil structure. The application of a combination of coffee husk compost and zeolite can fix several physical soil properties and groundnut production. As a versatile plant, peanuts have many uses in the culinary arts, cosmetics, feed, and more. This research aims to determine the effect of coffee husk compost and zeolite on the physical quality of Inceptisol soil and the weight of peanut seeds (Arachis hypogaea L.), as well as the interaction of coffee husk compost and zeolite. From May to September 2024, researchers in Deli Serdang Regency visited Sei Mencirim Village. The research used a factorial randomized block design (RAK) with a maximum of three replications for each of the two components. To start with, there are three different treatment doses for coffee husk compost: zero tonnes/ha (K0), fifteen tonnes/ha (K1), and twenty tonnes/ha (K2). Second, there are three levels of zeolite dosage: zero tons/ha (Z0), five tons/ha (Z1), and ten tons/ha (Z2). Soil content density, soil porosity, and permeability values were all improved by adding 20 tons/ha of coffee husk compost, but peanut seed weight was not affected. At a dose of 10 tons/ha, zeolite application increased soil permeability but had no impact on content density, soil porosity, or peanut seed weight. The interaction between coffee husk compost and zeolit did not affect soil physical properties and peanut seed weight.
