Abstract

The height of one of the external factors that affect production. Chlorophyll is one of the factors that can affect palm oil production. There are several other factors that affect the productivity of oil palm plants, namely climate, territorial shape, soil conditions, planting material, and cultivation techniques. Altitude (altitude) is one of the outside factors that affect production. Differences in altitude cause differences in productivity so that production data need to be analyzed and compared. Height differences cause differences in productivity so production data need to be analyzed and compared. This research was conducted in the Bah Birung Ulu PTPN IV in April-June 2018. This study aims to determine the effect of altitude in the highlands area the effect of the amount of leaf chlorophyll on the production of oil palm fruit (Elaeis guineensis Jacq.). The method used is descriptive analytic method by processing secondary data (LM 76) and take leaf samples and measure chlorophyll content using chlorophyll meters. The results showed that in the highlands (Kebuna Bah Birung Ulu) had the highest production in 2006, amounting to 22,976 Ton / ha / year. The highest amount of chlorophyll of palm oil was found in the 2005 planting year, which was 80.5 CCI. The largest production of oil palm is in the 2006 planting year of 22,976 Ton / ha / year with 3,148 mm / year of rainfall.

Abstract

Minyak kelapa sawit (Elaeis guineensis Jacq) sebagai sumber minyak nabati penting selain kelapa, kacang-kacangan, jagung, dll. Salah satu teknik teknis budidaya yang diharapkan dapat mempercepat pertumbuhan benih dengan pemberian pupuk makro dan pemberian pupuk kandang sebagai pengganti pupuk konvensional. Pemberian pupuk konvensional pada kelapa sawit merupakan tanaman yang sulit dan berbahaya untuk rusak atau mati jika penerapannya tidak hati-hati. Tindakan pendistribusian pupuk kandang yang masih tersedia dalam jumlah banyak diharapkan dapat mengatasi perusahaan kelapa sawit, serta meminimalisir pengeluaran pupuk dan mengurangi penggunaan pupuk konvensional. Berdasarkan hal tersebut maka dilakukan pengaruh pemberian dosis pupuk kandang terhadap pertumbuhan kelapa sawit. Penelitian ini dilaksanakan di lapangan percobaan Kampus STIPAP Medan Sumatera Utara. Waktu penelitian dimulai dari bulan April sampai dengan Juli 2018. Penelitian ini menggunakan RBP program non faktorial (Program Acak Kelompok) dengan 5 perlakuan dan 6 ulangan dengan hasil berjumlah 30 biji. Sistem perlakuannya adalah K0: kontrol (pupuk NPK 16:16:16), K1: pupuk kandang (dosis 0,6 kg / polibag), K2: pupuk kandang (dosis 1,5 kg / polibag), K3: pupuk kandang (dosis 2 , 4 kg / polibag), K4: pupuk kandang (dosis 3,3 kg / polibag). Hasil penelitian pengaruh pemberian dosis pupuk kandang dengan pengendalian pupuk NPK berpengaruh terhadap parameter tinggi dan tidak signifikan untuk parameter daun, batang, bobot basah dan bobot kering tanaman.
