Superior seeds are critical in increasing oil palm productivity in Indonesia, especially for smallholder farmers. Producers who produce oil palm planting materials play a vital role in providing quality seeds whose purity can be guaranteed (legitimized). The Indonesian Oil Palm Research Institute (IOPRI) is the only state-owned palm oil seed producer. The superior varieties of IOPRI, which are produced to increase palm oil production, will impact consumer behavior in selecting palm oil seeds. This research analyzes consumer attitudes, preferences, and satisfaction regarding using superior varieties of IOPRI germinated oil palm seeds. The data used in this research is primary data, with a total sample of 44 farmers. The analytical methods used are the Fishbein, Konjoin, Importance, and Performance Analysis (IPA) methods and the Customer Satisfaction Index (CSI). The research results show consumer attitudes towards the overall attributes of PPKS superior seed using the Fishbein method are in the very like category with a score of 24.04. Meanwhile, the preferences of farmers using conjoint analysis are very favorable, namely for Fresh Fruit Bunches (FFB) production potential of 38 tonnes/ha/year, high growth rate of 62.5 – 65 cm/year, tolerance to Ganoderma sp., planting density of 130 trees/ha, cardboard packaging, purchase by coming in person, 10% discount, and price Rp. 8000. IPA analysis shows that the suitability of varieties with planting density and the suitability of varieties with land type are included in quadrant I, so these two attributes do not satisfy farmers and are the main priority in making improvements. Meanwhile, consumer satisfaction with all attributes of the superior IOPRI variety shows a CSI value of 81%. The result shows that the farmer satisfaction index for IOPRI germinated oil palms seeds is very satisfied.

2025-04-25T04:29:53+00:00

The area of oil palm plantations in Indonesia is increasing from 14.0 million ha in 2017 to 16.8 million ha in 2022, which implies an increase in the need for harvesting and maintenance labour. Currently, in Indonesia, it is increasingly difficult to find trained field labour, especially in harvesting and loading Fresh Fruit Bunches (FFB) in the palm oil industry. In the industrial era 4.0, the use of mechanisation is a potential solution to overcome labour scarcity in the agriculture and plantation sectors. Mechanisation in harvest management involves the use of tools such as: tractor scissor lift grabber, quick tractor, crawller dump, along-along, wintor and truck bin system which functions to evacuate FFB from the collection point (TPH) to delivery to the palm oil mill (PKS). This study aims to evaluate the advantages and disadvantages of the use of mechanisation in the process of transporting production and analyse its financial feasibility through the NPV, IRR, B/C and PP analysis methods. The calculation results showed that the truck bin system obtained an NPV value of Rp 424 million, IRR 21.38%, B/C 1.21, PP 5 years. tractor scissor lift grabber obtained NPV IDR 433 million, IRR 22.5%, B/C 1.28, PP 5 years, quick tractor obtained NPV IDR 39 million, IRR 23.91%, B/C 1.11, PP 3 years, wintor reached NPV IDR 45 million, IRR 26.05%, B/C 1.27, PP 3 years, and Along-along recorded NPV IDR 78 million, IRR 212.1%, B/C 1.49, PP 1 year. The results of this study show that mechanisation is technically and economically feasible in oil palm plantations.

The Effect of Application of Mycorhyza and Inorganic Fertilizers on The Growth of Palm Seedlings in Pre and Main Nursery

Fertilization is one of the factors that affect oil palm productivity. Three types of fertilizers are commonly used for oil palm cultivation, namely organic, inorganic, and biological. One type of biological fertilizer is mycorrhiza, a fertilizer made from fungi. This study aims to determine the role of mycorrhiza and various doses of NPK fertilizer on the vegetative growth of oil palm seedlings. The research method in the pre-nursery used a completely randomized design (CRD) with treatments; control (A), 100% NPK fertilizer (B), 30 g mycorrhiza (C), 30 g mycorrhiza + 25% NPK fertilizer (D), 30 g mycorrhiza + 50% NPK fertilizer (E) 30 g mycorrhiza + 75% NPK fertilizer with 25 replications. The research method in the main nursery used a completely randomized design (CRD) with treatments: control (A), 100% NPK fertilizer (B), 40 g mycorrhiza (C), 40 g mycorrhiza + 25% NPK fertilizer (D), 40 g mycorrhiza + 50% NPK fertilizer (E) 40 g mycorrhiza + 75% NPK fertilizer with 20 repetitions. The results showed that the application of 30 g mycorrhiza to pre-nursery oil palm seedlings could increase seedling height by 73.75% better than the control, and the application of 30 g mycorrhiza + 50% NPK fertilizer could increase seedling height by 59.57%. Applying 40 g mycorrhiza + 75% NPK fertilizer could increase height by 71.97% and diameter by 54.26% compared to the control in main-nursery oil palm seedlings. The application of 30 g of mycorrhiza in the pre-nursery can increase the efficiency of NPK fertilizer by 50%, and the application of 40 g of mycorrhiza in the main nursery can increase the efficiency of NPK fertilizer by 25%.

Microorganism Identification of Contaminant on Oil Palm (Elaeis guineensis Jacq.) Tissue Culture

2025-04-25T04:29:53+00:00

The issue of oil palm tissue culture is that the risk of microorganism contamination in its every process. Microorganism contamination can hinder the growth and development of explants, even causing them to fail to grow. The mostly types of contamination found in tissue culture are bacteria and fungi. Contaminating microorganisms can thrive in tissue culture media due to the presence of nutrients. This research aims to determine the type of contamination in oil palm tissue culture and, if necessary in the future, determine the use of antibiotics as a preventive measure against contamination in the tissue culture process. The research methods used purvosive sampling which included sample criteria, sample selection, sample verification followed by isolation, purification, and microscopic/macroscopic observation. The results revealed two genera from fungal isolates, namely Aspergillus sp. and Penicillium sp. through microscope observation with 1000x magnification. Additionally, four bacterial isolates were identified as gram-negative and one as gram-positive through the gram test using 3% KOH. The highest abundance of bacterial isolates was shown in sample 3, with 2,9 x 105 CFU/mL. Microscopic morphology included round (coccus), rod-shaped (bacillus), and spiral shapes. To control the microorganisms, antibiotics such as Tetracycline, Ciprofloxacin, and Kanamycin, as well as antifungals like fluconazole and ketoconazole. To prevent microorganisms is managed by sterilizing tools and materials, selecting sterilant substances, sterilization techniques, clean culture room conditions, monitoring and periodically removing contaminated cultures.

(Single Nucleotide Polymorphism (SNP) Analysis of the Laccase-24 (EgLCC24) Gene in the Resistance of Oil Palm (Elaeis guineensis Jacq.) to Ganoderma boninense)

2025-04-25T04:29:53+00:00

Ganoderma boninense attack and its rapid spread in oil palm plantations have caused significant economic losses. The use of Ganoderma resistant plant materials can be a solution, but the allelic segregation that occurs causes not all DxP progeny obtained have the nature of resistance to Ganoderma. The role of molecular markers is needed to assist initial selection of Ganoderma resistant DxP progenies in nurseries. This study aims to identify targeted SNP markers from the Laccase-24 gene (EgLCC24), which is thought to play a role in oil palm resistance to Ganoderma. Three oil palm DxP populations were used in this study, namely populations A, B, and C. Ganoderma screening in nurseries was carried out on these three populations to obtain progeny samples with resistant and susceptible phenotypes, which were then further analyzed. The methods used include SNP analysis and the use of SNAP primers for marker development. The SNP differences obtained from this study led to amino acid changes, but did not cause stop codons. The validation results using SNAP primers on the Laccase-24 gene showed that DxP progeny from populations A, B, and C relatively have moderate allele characteristics of Ganoderma resistance.
