Abstract

Replanting is a strategic effort to increase the productivity of oil palm plantations. This effort requires the procurement of quality seedlings, so that maintenance absolutely gets the main attention. This study aims to determine the benefits of co-products to increase nutrient use efficiency (NUE) and the growth of oil palm seedlings in the main nursery. This study used a completely randomized block design with treatments of oil palm co-products (empty bunches, mesocarp fiber, suspended solids applied as mulch on the surface of polybag media, and without co-products) and NPKMg (15:15:6:4) at the rate of 8, 10 and 12 grams/two weekly/seedlings. The treatment  applied at transplanting seedlings from PN to MN until the age of 8 months. The results showed that the growth of oil palm seedlings and NUEwere influenced by the types of co-products and NPKMg rates. Application of oil palm co-products (empty bunches, mesocarp fibers and suspended solids) as surface mulch and NPKMg fertilizer (15:15:6:4)  of 12, 10, and 8 grams/two weekly/seedling can increase the growth of 8-month-old MN oil palm seedlings. The better seedling growth was produced by the application of 8 grams of fertilizer/two weekly/seedling and empty bunches. Application of all co-products can improved NUE in MN nurseries. Improvement of  NUE along with the decrease in the dose of NPKMg application (8 ?10?12 grams/two weekly/seedling).

Abstract

The root system of oil palm (Elaeis guineensis Jacq.) is a critical component for plant growth. Roots play essential roles in water and mineral absorption, providing structural support, storing energy, and facilitating interactions between plants and microorganisms. In tissue culture, root initiation is one of the key parameters for the successful formation of plantlets. This study aims to analyze the response of growth regulators in inducing roots and increasing the percentage of root formation in oil palm plantlets in vitro using 1-naphthaleneacetic acid (NAA) and indole-3-butyric acid (IBA). The methods included plant material preparation, root growth medium preparation, treatment media preparation, inoculation and incubation, and data analysis. The experimental design employed a Completely Randomized Design (CRD) with nine treatments and one control, each repeated seven times, resulting in 70 experimental units. The data were analyzed using ANOVA, followed by further testing with DMRT at a 5% significance level. The results showed that NAA and IBA positively influenced root formation in oil palm plantlets. A single NAA treatment effectively stimulated root elongation and reduced the time required for root emergence. The combination treatment of 1 mg/L NAA + 2 mg/L IBA produced a higher number of roots in the plantlets.

Abstract

Pertumbuhan bibit kelapa sawit sangat dipengaruhi oleh kualitas media tanam, termasuk kandungan bahan organik yang digunakan. Lamanya dekomposisi bahan organik turut menentukan ketersediaan unsur hara bagi tanaman sejak awal pertumbuhan. Penelitian ini bertujuan untuk mengkaji pengaruh jenis bahan organik dan lama dekomposisi terhadap pertumbuhan bibit kelapa sawit pada budidaya pra-pembibitan. Penelitian ini menggunakan percobaan faktorial dengan rencana acak lengkap (RAL) yang terdiri dari dua faktor dan tiga kali ulangan. Faktor pertama adalah berbagai jenis bahan organik (pupuk kandang, legum, eceng gondok). Faktor kedua adalah lama dekomposisi bahan organik yang diamati pada minggu pertama, kedua, dan ketiga. Data hasil penelitian dianalisis menggunakan analisis ragam (ANOVA) dengan taraf nyata 5%. Apabila terdapat perbedaan nyata dilanjutkan dengan Uji Jarak Berganda Duncan (UJT) pada taraf nyata 5%. Hasil penelitian ini secara umum menunjukkan bahwa bahan organik legum memberikan hasil yang lebih stabil dan cenderung lebih baik dibandingkan pupuk kandang dan eceng gondok untuk semua parameter pertumbuhan bibit kelapa sawit pada tahap pra-pembibitan. Secara statistik, hasilnya tidak menunjukkan perbedaan yang signifikan antar perlakuan. Namun secara numerik, bahan organik legum lebih konsisten dalam mendukung pertumbuhan vegetatif bibit kelapa sawit. Penelitian ini tidak hanya memberikan kontribusi pada aspek teknis budidaya tetapi juga meningkatkan pemahaman tentang manfaat biomassa legum sebagai sumber nutrisi yang efektif dan efisien dalam mendukung pertumbuhan awal bibit kelapa sawit.

Abstract

Environmental factors greatly influence oil palm productivity, especially rainfall, which impacts the plant's physiological state. This study aims to analyze the relationship between rainfall and oil palm production. This study used a two-stage survey method. Time series data from 2016-2021 were used to evaluate the relationship between monthly rainfall and three production parameters (productivity, number of fresh fruit bunches (FFB), and average bunch weight (ABW). Correlation and regression analyses were conducted to identify significant contributions of rainfall to yield variables by considering the time lag. The results showed that rainfall that occurred 24-36 months previously had a significant effect on productivity and the number of FFB with R2 values of 53.93% and 54.83%, and rainfall 37-38 months previously contributed to BJR with an R2 value of 40.33%. Rainfall has historically played an important role in determining oil palm yields. Plantation management based on long-term climatological data can be a new approach to optimizing sustainable oil palm production.

Abstract

Orchid Ph. amabilis is one of the plants designated as "Indonesian National Flower" and designated as "Puspa Pesona Indonesia". Orchid Ph. amabilis has a diversity that is not widely known, so that it is necessary to identify it molecularly. DNA isolation is the first step in molecular testing. This study aims to determine the sample weight, incubation time and the appropriate isolation method for DNA isolation from samples of Ph.amabilis orchid roots. In this study, the DNA isolation stage used two experimental methods, namely the CTAB method (Murray and Thompson) and the mini kit. The research method used was a single factor experiment with a combination of sample weight and incubation time consisting of 6 treatments with 3 replications, so 18 experimental units were obtained. The experimental treatment used was from the roots of the orchid Ph. amabilis which has a sample weight of 0.25 g, 0.5 g, and 0.75 g and each sample weight treatment was incubated for 30 minutes and 60 minutes. In addition, DNA isolation using the kit method had a sample weight of 0.25 g, 0.5 g and 0.75 g and an incubation period of 10 minutes. The results showed that the DNA isolation of Ph. amabilis with a sample weight of 0.75g, incubation time of 30 minutes using the CTAB method showed the best treatment in producing DNA with a concentration of 384 ng/µl and a purity of 1.9. This study is expected to provide information on sample weight, incubation time and the appropriate method for DNA isolation of Ph. amabilis orchid roots.

Abstract

This study analyzed the reliability and failure risks of screw press machine components in a palm oil loose fruit mill using the Failure Mode and Effect Analysis (FMEA) method. The objective was to identify critical components, evaluate their Risk Priority Number (RPN), and propose appropriate maintenance strategies. Data were collected through questionnaires, field observations, and maintenance records. The RPN was calculated by multiplying severity, occurrence, and detection scores, while reliability was assessed using the Mean Time Between Failures (MTBF) formula. The worm screw showed the highest RPN at 252, indicating a critical risk level, while the press cage followed with an RPN of 210. MTBF analysis revealed that the worm screw required replacement every 313.5 hours, whereas components like the V-belt and electro motor had longer MTBF intervals of up to 3135 hours. The findings suggested that targeted maintenance on high-risk components could reduce downtime and enhance production efficiency. This study concluded that prioritizing preventive maintenance based on RPN and MTBF results was crucial for maintaining the operational performance of screw press machines in palm oil processing.

Abstract

Oil palm canopy is formed every month as many as 1-3 fruits, depending on the age and growth of the plant. Each oil palm canopy supports the formation of leaf/frond positions that are arranged in a spiral. Progressive pruning of the main shoots is carried out directly by harvest workers (not the Special Main Shoot Work Team) and is carried out simultaneously when cutting the fruit while still referring to the basic principle of the number of productive fronds that must still be maintained according to the provisions (leaf area index). This study aims to determine the role of the progressive pruning system in minimizing looses (bunches and looses fruit) in oil palm plantations. The basic method used in this study is a quantitative descriptive method using t-test analysis, the parameters used are the looses of bunches and looses fruit. The conclusion of the study is that the progressive pruning system can reduce losses of oil palm fruit (bunches) and loose fruit, compared to the periodic pruning system at the overall looses point of the three looses point chains, namely at the main, plate and market.

Abstract

Fuel sources derived from oil palm plants are abundant but have not been optimally utilized by the community. This study aims to show the performance efficiency of cheap fuel fruitless (Brondolan) using people's stoves as fuel substitutes for kerosene, coal, and Liquid Petroleum Gas (LPG). This study uses a quantitative observation method. The types of fuel and stove materials used include (1) conventional kerosene-fired stoves, (2) conventional LPG-fired stoves, (3) gasified biomass stoves fueled with palm fruit, (a) large stove size (Prime Brand), and (b) small stove size (People's Stove Brand). The research procedure is measured by heating 5 liters of water from room temperature to boiling (1000C). The results show that fruitless is more efficient than gasoline, coal, and LPG is more efficient. Based on trials, heat 5 liters of water to a boil at Rp. 200, Gasoline Rp. 1,650, and LPG Rp. 381. The government's role is to provide socialization and policies in applying alternative materials with lozenges to reduce the use of gasoline and LPG. Unrefined fuel can be an alternative material for household scale stoves.
