Abstract

ABSTRAK Tanaman kelapa sawit merupakan komoditi perkebunan yang berperan penting dalam memajukan perekonomian negara. Provinsi Jambi merupakan salah satu sentra perkebunan kelapa sawit di Indonesia. didominasi oleh perkebunan rakyat yang umumnya dikelola secara kurang tepat sehingga menyebabkan produktivitas kelapa sawit Provinsi Jambi (3.506 kg/ha) lebih rendah dari produktivitas Nasional (3.873 kg/ha) dan berakibat pada meluasnya areal TTM/TR. Tujuan penelitian ini adalah untuk mempelajari pengaruh pemberian dan memperoleh dosis terbaik kompos pelepah kelapa sawit dan pupuk NPKMg terhadap pertumbuhan bibit kelapa sawit (Elaeis guineensis Jacq.). Penelitian ini dilaksanakan di Teaching and Researce Farm Fakultas Pertanian Universitas Jambi dan berlangsung selama bulan, dimulai pada bulan Juli-Oktober 2022. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 6 perlakuan yaitu: p0 = 100% NPKMg (rekomendasi), p1 = 20% kompos pelepah kelapa sawit + 80% NPKMg (R), p2 = 40% kompos pelepah kelapa sawit + 60% NPKMg (R), p3 = 60% kompos pelepah kelapa sawit + 40% NPKMg (R), p4 = 80% kompos pelepah kelapa sawit + 20% NPKMg (R), p5 = 100% kompos pelepah kelapa sawit. Variabel yang diamati meliputi pertambahan tinggi (cm), pertambahan diameter bonggol (mm), pertambahan jumlah daun (helai), bobot kering tajuk (g), bobot kering akar (g) dan rasio tajuk akar. Hasil penelitian menunjukkan bahwa pemberian kompos pelepah kelapa sawit dan pupuk NPKMg mampu meningkatkan pertumbuhan pada variabel pertambahan diameter bonggol dan pertambahan jumlah daun. Namun, belum mampu meningkatkan pertambahan tinggi bibit, bobot kering tajuk dan bobot kering akar serta memperoleh rasio tajuk akar yang baik. Dosis 60% kompos pelepah kelapa sawit + 40% NPKMg memberikan rata-rata pertumbuhan terbaik bibit kelapa sawit umur 6 bulan di pembibitan utama. Disamping itu, pemberian kompos pelepah kelapa sawit dapat mengurangi penggunaan pupuk NPKMg sebesar 60% atau 30 g/bibit. Kata Kunci : Pembibitan Utama, Kompos Pelepah Kelapa Sawit, Pupuk NPKMg ABSTRACT Oil palm is a plantation commodity that plays an important role in advancing the country's economy. Jambi Province is one of the centers of oil palm plantations in Indonesia. dominated by smallholder plantations which are generally managed in an inaccurate way, causing Jambi Province's oil palm productivity (3,506 kg/ha) to be lower than the National productivity (3,873 kg/ha) and resulting in the expansion of the TTM/TR area. The purpose of this study was to study the effect of applying and obtaining the best dose of palm frond compost and NPKMg fertilizer on the growth of oil palm seedlings (Elaeis guineensis Jacq.). This research was conducted at the Teaching and Research Farm, Faculty of Agriculture, University of Jambi and lasted for months, starting from July-October 2022. This study used a Randomized Block Design (RBD) with 6 treatments, namely: p0 = 100% NPKMg (recommendation), p1 = 20% palm frond compost + 80% NPKMg (R), p2 = 40% palm frond compost + 60% NPKMg (R), p3 = 60% palm frond compost + 40% NPKMg (R), p4 = 80% palm frond compost + 20% NPKMg (R), p5 = 100% palm frond compost. Variables observed included height increase (cm), increase in tuber diameter (mm), increase in the number of leaves (strands), shoot dry weight (g), root dry weight (g) and root crown ratio. The results showed that the application of palm frond compost and NPKMg fertilizer was able to increase growth in the variable increase in weevil diameter and increase in the number of leaves. However, it has not been able to increase the increase in seedling height, shoot dry weight and root dry weight and obtain a good root canopy ratio. Dosage of 60% palm frond compost + 40% NPKMg gave the best average growth of 6 months old oil palm seedlings in the main nursery. In addition, applying palm frond compost can reduce the use of NPKMg fertilizer by 60% or 30 g/seed. Keywords : Main Nursery, Palm Frond Compost, NPKMg Fertilizer
