Abstract

The best plant media used in early seeding of oil palm is top soil with a thickness of 10 to 30 cm. Top soil is a layer of soil with high organic content, but at present its availability is rarely found so it needs a solution as its replacement. A alternative is to use organic material ash boiler with wood charcoal. This study aims to determine the effect of ash boiler and wood charcoal as a medium to grow against some indicators of oil palm seed growth. This research was conducted from February to May 2017. The experimental design used was a complete randomized design of one factor, namely P0: 100% sub soil (without wood charcoal and boiler ash), P1: 10% ash boiler + 10% charcoal wood + 80% sub soil, P2: 20% ash boiler + 20% wood charcoal + 60% sub soil, P3: 30% ash boiler + 10% charcoal + 60% sub soil, P4: 10% ash boiler + 30% wood charcoal + 60% sub soil. Each treatment was repeated 2 times, so there were 10 experimental units. Each experimental unit consists of 2 samples. The total number of plants is 20 plants. The result of the research shows that the ash of boiler and charcoal have significant effect on the growth of plant morphology (plant height, stem diameter, number of leaves), and plant physiology (boimassa plant), but no significant effect on leaf area parameters.

Abstract

Organic fertilizers are environmentally friendly fertilizers made from natural ingredients so that the use of organic fertilizers does not pollute the environment and damage the soil. Oil Palm Empty Bunches (TKKS) is one of the wastes from palm oil processing which can be used as solid organic fertilizer. At present, the potential for utilizing TKKS as a raw material for making organic fertilizers is very large. This study aims to determine the technique of making organic fertilizers with basic ingredients of TKKS fi bers and earthworms (Lumbricus rubellus), and find out the nutrient content contained in them. This research was carried out by an experimental method on an organic fertilizer maker or unit. Based on the results of the study, solid organic fertilizers can be made with basic TKKS ingredients and the decomposition process using earthworms (Lumbricus rubellus). In 100 grams of solid organic fertilizer produced containing nutrients namely Na dd (cmol/kg) (0.44), Total N (0.24%), P Total (mg P2O5/100g) (133.54%), Total K (mg K2O/100 g) (147.92), Mg (0.01), Za (55.62) and Fe (44.117).

Abstract

The existence of weeds in oil palm plantations is considered very detrimental and even has no benefit at all. However, it turns out that there are several weeds in oil palm plantations that can be used, one of which is a medicinal plant. Some of these weed species are considered by the plantation community as an alternative to making traditional medicines considering that the oil palm plantation areas are very far from pharmaceutical centers. This research was conducted at the oil palm plantation of PT Unggul Widya Teknolgi Lestari, Pasangkayu Regency, West Sulawesi, in March-June 2020. The purpose of this study was to determine the types and methods of processing weeds as traditional medicines by the oil palm plantation community. The methods used in this research are field observations, in-depth interviews with key informants from community elements and oil palm plantation managers. Qualitative descriptive analysis is used to explain the results of surveys and interviews systematically which is strengthened by literature study. Based on the results of the study showed that in the oil palm plantation PT Unggul Widya Teknologi Lestari, there are 10 weed plants which are commonly used by plantation communities as traditional medicine. The processing method includes the boiling method and using it directly. The use of weed plants as traditional medicine also contributes to efforts to control weeds in an environmentally friendly and sustainable manner in oil palm plantations.

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

This research discusses the effectiveness of the modified palm oil loose fruit collecting tool at the productive plant. This research was conducted in community oil palm plantations in Desa Lubuk Bento Village, Kecamatan Pondok Suguh, Kabupaten Mukomuko, Provinsi Bengkulu, from 2020, 26th May to 2020, 30th July. The research purpose was to obtain alternative palm oil loose fruit collecting tool at the productive plant, as well as to determine the effect the use of modified palm oil loose fruit collecting tool to the effectiveness and efficiency of palm oil loose fruit collecting activities. The research method used is a functional design in terms of function or usefulness of the modified collecting tool. This research consist of two stages, ie: 1) literature study and tool design; and 2) the process of assembling and testing the tool. The parameters observed were the palm oil loose fruit collecting time, as well as the number and quality of palm oil loose fruit collected. The result showed that the use of modified palm oil loose fruit collecting tool could increase work performance from 0.21 WD/ha to 0.13 WD/ha.

Abstract

Increasing the area of ??oil palm plantations in Indonesia must be accompanied by a plantation land optimization program so as to provide maximum results in maintaining the sustainability of plantation land in the future. One of the optimization of plantation land is intercropping. This study aims to determine the implementation model of oil palm and watermelon intercropping in smallholder oil palm plantations. This research was conducted directly in the field using the Demonstration Plot (Demplot) method of intercropping oil palm and watermelon. In this method, observations include observations of the condition of the land, soil conditions, physical conditions of oil palm plants and the condition of watermelons. In addition, the in-depth interview method was also conducted for farmers to get an explanation of the process of land preparation, planting, maintenance, and harvesting. The results showed that the implementation of the oil palm and watermelon intercropping model was economically very profitable, reaching Rp. 6,488,800/hectare/season. On the environmental aspect, the intercropping method in oil palm plantations has a very good impact on soil conditions in retaining water, maintaining moisture, and preventing soil erosion.

Abstract

Cow dung and leaves of Pueraria javanica are organic wastes that highly available and content nutrients. Generally, there is a lot of Pueraria javanica’s leaf waste in oil palm plantations that will have mature period. Both of these wastes could be used as liquid organic fertilizer that has advantage of being easier to apply and could be watered at the same time. It will also more profitable when the application doing in the dry season. The purpose of this study are to obtain alternative organic waste and determine the nutrient content of the best liquid organic fertilizer. This research conducted at PT Rea Kaltim, East Kalimantan, from May to September 2022. This research used a descriptive method consisting of observation, literature study and interviews. Liquid organic fertilizer treatment consisted of 4 mixtures, there are P0 (1 kg of cow dung + 0 kg of Pueraria javanica), P1 (1 kg + 0,25), P2 (1 kg + 0,5 kg), P3 (1 kg + 0,75 kg), and P4 (1 kg + 1 kg). The result of research showed that cow dung and Pueraria javanica could be used as alternative organic materials for the manufacture of liquid organic fertilizer. Based on the results of analysis, the best nutrient content in liquid organic fertilizer was found in the treatment of 1 kg of cow manure and 1 kg of Pueraria javanica with 0,21% nitrogen, 0,12% phosphorus and 0,20% potassium.
