Abstract

Beberapa area di Provinsi Sumatera Selatan memiliki faktor penghambat untuk pertumbuhan kelapa sawit yang optimal karena penyebaran curah hujan yang tidak merata sepanjang tahun, sehingga sering mengalami bulan kering yang panjang (Juli - Oktober), dan bulan lainnya merupakan bulan hujan yang dapat menyebabkan erosi. Penelitian ini bertujuan untuk mengukur tingkat bahaya erosi melalui prediksi erosi menggunakan metode USLE dan membuat rekomendasi untuk tindakan konservasi di Perkebunan Kelapa Sawit PT. Mutiara Bunda Jaya – Kebun Inti Permata Bunda Dua di Desa Balian Kecamatan Mesuji Raya Kabupaten Ogan Komering Ilir Palembang. Penelitian ini menggunakan metode deskriptif melalui survey lapangan dengan teknik sampling berdasarkan Satuan Peta Lahan, dilanjutkan menggunakan metode USLE untuk memprediksi erosi. Parameter yang diamati yaitu erosivitas hujan, erodibilitas tanah, panjang dan kemiringan lereng, tanaman, dan tindakan konservasi tanah. Hasil penelitan menunjukkan laju erosi di Perkebunan kelapa sawit PT. MBJ - IPBD berkisar   2,49 - 18,00 ton/ha/tahun. Laju erosi terendah terjadi pada SPL 28 dengan jenis tanah Plinthic Kanhapudults, kelerengan datar dengan tanaman tahun tanam 2008. Laju erosi tertinggi terjadi pada SPL 16 dengan jenis tanah Typic Dystrudepts, kelerengan landai dengan tanaman tahun tanam 2006. Tingkat bahaya erosi sangat rendah sebesar 91,21% atau 1.077,96 Ha dan tingkat bahaya erosi ringan sebesar 8,79% atau 103,88 Ha dari keseluruhan area sampel pada PT. MBJ - IPBD. Tindakan konservasi yang direkomendasikan yaitu pembuatan rorak.   Kata Kunci : Metode USLE, Prediksi erosi, Rekomendasi tindakan konservasi

Abstract

This study aims to determine the interactions and main applications of solid and biological POC fertilizers on the growth and production of shallots and cayenne pepper in an intercropping system. This study used a 2-factorial Completely Randomized Design (CRD). The first factor is solid fertilizer, with 4 levels: 0, 500, 1000, and 1500 g/plot, while the second factor is biological POC, with 4 levels: 0, 2, 4, and 6 ml/L water. There were additional 2 units of experiments for the monoculture planting of shallots and cayenne pepper. The results showed that the interaction between solid and biological POC was not significant for shallot parameters. Still, the main effect of solidity was significant on height, number of tubers, wet weight per clump, and dry weight per clump, with the best dose of 1500 g/plot, while the main effect of biological POC was significant on wet weight per clump and dry weight per clump, with the best concentration of 4 ml/L water. The interaction of solid and biological POC was significant on the height of cayenne pepper, with the best treatment of 1500 g/plot and 4 ml/L of water, while the main effect of solid was significant on height, flowering age, productive branches, and residual fruit, with the best dose of 1500 g/plot, but the main effect of biological POC was not significant for cayenne pepper. The best land-to-water ratio was 3.78 with no solid treatment and 2 ml/L POC water.
