Abstract

The press station is the main station for quoting oil from the pulp of palm oil (CPO). In the screw press, there are several things that need to be considered in order to determine the success of the extraction process, namely the percentage level of oil losses which is one of the benchmarks for the success of extraction at the press station. Some things that can affect the percentage level of oil losses at the press station are the amount of pressure on the press machine and the level of chopping blades in the digester. This observation is carried out by direct observation method at PT. Palmina Utama, using a purposive sampling method.samples taken for the analysis of oil losses at this press station are in the form of fiber, the persentage value of oil losses is determined by exstraction using soxhlet with n-hexane solvent. Samples for analysis were taken from five press machines at the press station in the form of fiber and taken three times each at three points, namely the left side, the middle side and the right side with an interval of two hours, then the samples were mixed and weighed as much as nine to ten gram. The highest oil losses in February were 4.48% and the lowest losses during February were 4.105%. Based on statistical analysis, that F-Count is smaller than F-table 5% and 1%. Thus, pressure does not affect at the percentage of oil losses.

Abstract

Weeds have a direct influence on the growth and yield of oil palm production, resulting in various losses. Weed control aims to suppress growth or destroy weeds in plantations. In order to reduce the risk of failure in weed control, weed inventory activities need to be carried out first. Weed inventory is an activity to collect data on the types of weeds, and is expected to reveal potential and information about weeds. The purpose of this study was to identify and recognize the diversity of weed species that can be used as the basis for weed control in the productive phase of oil palm plantations at the Plantation Seed Monitoring and Certification Center. The method used in this study was a descriptive qualitative approach. The results of the study found 2 divisions, 4 classes, 13 orders, 18 families, 22 genera and 22 plant species on oil palm plantations with narrow, broad, and ferns. In general, based on the results of the inventory, broadleaf weeds were more common than narrow leaf weeds and fern weeds.

Abstract

Limbah solid merupakan limbah yang dihasilkan dari pembuatan CPO (Crude Plam Oil) minyak kelapa sawit di PKS (Pabrik kelapa sawit) yang menggunakan sistem decanter. Pada penelitian ini limbah solid dimanfaatkan sebagai media tanam jeruk manis. Tujuan dari penelitian ini adalah mengetahui cara pembuatan media tanam dengan penambahan limbah solid kelapa sawit dan mengetahui respon pertumbuhan bibit tanaman jeruk pada fase vegetatif pada media tanam yang ditambahkan limbah solid kelapa sawit. Pada penelitian ini, menggunakan 5 perlakuan yaitu F0 (Tanpa Pemberian solid kelapa sawit (Kontrol)), F1 (Pemberian solid 120 g/polibag), F2 (Pemberian solid 160 g/polibag), F3 (Pemberian solid 200 g/polibag), F4 (Pemberian solid 240 g/polibag). Parameter yang diamati adalah tinggi tanaman, jumlah helai daun, dimeter lingkar batang, dan panjang akar. Berdasarkan hasil penelitian limbah solid kelapa sawit memberikan hasil lebih baik dibanding kontrol pada semua parameter, namun tidak berbeda signifikan secara statistik. Perlakuan F1 memberikan rata-rata tinggi tanaman lebih baik, yaitu 9,3 cm dan rata-rata helai daun sebesar 6,15 helai.
