Abstract

The problem that arises in plant cultivation is the limitation of top soil as a planting medium, one of the substitutes for top soil is litter. Litter comes from weathering of male flowers, female flowers and sheath weathering which have decayed and become organic matter. The aim of the study was to determine the effect of armpit litter growing media on oil palm trunks on the growth of Pueraria javanica, determine good media, and determine the nutrient content of armpit litter on oil palm trunks. The research was carried out in the experimental garden 1 Politeknik Kelapa Sawit Citra Widya Edukasi from February to April 2018. This study used a Complete Randomized Block Design (RAKL), with treatment A1: 100% Top Soil, A2: Litter 100%, A3: Subsoil 80% + litter 20%, A4: Subsoil 60% + litter 40%, A5: Subsoil 40% + litter 60%. One treatment had three replications, and each replication consisted of three samples. If there is a real effect, it is tested further with the DMRT test (Duncan Multi Range Test) 5%. The parameters of observation were plant height, stem diameter, number of leaves, leaf area, wet weight and dry weight. Based on the results of the study, giving litter of oil palm midrib armpit significantly affected the growth of Pueraria javanica, such as plant height from age 1 and 2 BST (Month after Planting) and stem diameter, number of leaves, leaf area at 2 BST (Month after Planting), A5 treatment has a good effect on plant height and leaf area, while A4 treatment is the best medium for stem diameter and number of leaves. Litter content is N 2.09%, P 0.08%, and K 0.179%.

Abstract

Rats are one of the pests of oil palm plantations that are very detrimental, so they must be controlled. The use of Tyto alba is an alternative that can be used to control rat pests biologically, as well as to maintain the balance of the ecosystem in oil palm plantations. The purpose of this study was to determine the ecological niche of Tyto alba and its maintenance techniques in oil palm plantations. The method used in this research is direct observation in the field accompanied by in-depth interviews with key persons who have in-depth knowledge of Tyto alba. The results of the observations were strengthened by literature study and the results were analyzed and evaluated in a descriptive qualitative manner. The results of this study indicate that based on the Food Chain analysis, Tyto alba occupies the top of the food chain so that its existence greatly determines the balance of the ecosystem in oil palm plantations. The maintenance of Tyto alba in oil palm plantations is carried out in Gupon (Owl Cage) which is located in the plantation area, so that Tyto alba is able to adapt from an early age to the conditions of oil palm plantations.

Abstract

The quality of Palm Kernel Oil (PKO) is influenced by the quality of the kernel to be processed. Meanwhile, the quality of the kernel is influenced by the temperature and duration time of drying. The purpose of this research was to determine the correlation between moisture content in the kernel and free fatty acid content in PKO. The research was conducted at PT XYZ. The method used to determine the moisture content in the kernel is drying using a microwave, while to determine the free fatty acid content in PKO is using titration. Data analysis method used is correlation analysis. The result showed that there was not a significant influence between the moisture content in the kernel and the free fatty acid content in PKO, so that if the moisture content in the kernel was higher, the free fatty acid content in PKO would not always be higher.

Abstract

Liquid organic fertilizer is a fertilizer made from the decomposition process of organic matter. Black soldier fly (BSF) larvae are used as organic fertilizer because they have a high protein content. This study aims to determine the content of BSF larvae liquid fertilizer (POCbsf) with pineapple and papaya extract as activators and the response to the growth of oil palm seedlings in early nurseries with BSF liquid organic fertilizer. This research was conducted in 2 stages, namely the stage of making POCbsf and the stage of testing POC on oil palm seedlings in early nurseries. This research was arranged in a non-factorial Completely Randomized Design (CRD). The experiments tested in this study were: P0 (without POC), P1: 0.1% POCbsf, P2: 0.5% POCbsf, P3: 1% POCbsf). Each study consisted of 4 treatments, with 3 replications, each replication consisting of 3 samples. The results showed that the amino acid content contained in POCbsf consisted of 17 types. The content of glutamic acid and aspartic acid in POCbsf with papaya extract activator was higher (0.14% and 0.08%) than POCbsf with pineapple extract activator (0.02% and 0.01%). Compared to the control, both POCbsf showed a positive increase in the growth of oil palm seedlings represented at 4 BST on plant height parameters (0.1% POCbsf A = 22.78 cm and 0.5% POCbsf B = 22.06 cm) and root length (0.5% POCbsf A = 15.9 cm; and 0.1% POCbsf B = 15.57 cm).

Abstract

The use of pre-emergence bioherbicide for controlling weeds could be alternatife because it more safe for environment and the process is easy to do. Bioherbicides could be made from weed waste around oil palm plantation, one of them is Ganda Rusa or Asystasia intrusa. These weeds contain allelochemical compounds that can inhibit various growth reactions in weeds and are dominance weeds in oil palm plantations. The objectives of this experiment were to obtain the alternative material for pre-emergence bioherbicide and to know the effectivity of pre-emergence Asystasia intrusa to weed’s growth and soil physical condition, and identify the dominant weed species that grow. This research conducted at research area in Desa Penarik, Kabupaten Muko-Muko, Bengkulu, from Januari until Februari 2021. This research was arranged in a factorial random block design with three replications and four treatments. The treatments are P0 (Control), P1 (Herbisida 1%), P2 (Bioherbicide 1 liter), P3 (Bioherbicide 2 liter). Each of treatments repeated three times. The data was analysis of variance at 5%, then it continued by Least Significance Different Test (LSD Test). The result showed that Asystasia intrusa could be as alternative material for pre-emergence bioherbicide and significantly affected to weed’s growth in 4 until 7 dayas after application. Bioherbicide 2 liter has potential to control weeds in oil palm plantation and not showed significantly difference to physics condition of Ultisol. The weed dominance it showed in area is Borreria alata.
