International Journal of Oil Palm (IJOP) is an online and print mode, a peer-reviewed research journal published by Indonesian Oil Palm Society (Masyarakat PerkelapaSawitan Indonesia, MAKSI), it provides a global publication platform for researcher, scholars, academicians, professionals and students engaged in research in oil palm industries. The main aim of IJOP is to become the world’s leading journal in oil palm that is preferred and trusted by the community through publishing authentic, peer-reviewed and scientifically developed research articles of international caliber. The journal is published three times in a year, 6-10 papers per publication, and the language of the journal is English. JOURNAL SCOPE IJOP publishes research papers in the felds of soil and crop fertilizer application, seedling preparation, cover crop management, leaf pruning, weed control, control of pest and diseases, insect pollinators management, water management, intercropping, cattle oil palm integration, environmental studies, harvesting technology, IT remote sensing GPS application, mechanization, sustainability standards, policy studies, social and economic studies, smallholders empowerment, palm oil mill improvement, biomass utilization, carbon footprint, water footprint, market studies, refinery, food and nutrition technology (oleofood, food safety, pharmaceutical, and nutraceutical) and also management of soil preparation, inorganic and organic safety, oleochemicals, downstream industry development, supply chain, and market studies. The published articles can be in the form of research articles, review paper or short communications which have not been published previously in other journals (except in the form of an abstract or academic thesis/dissertation or presented in seminar/conference).

Abstract

The continuous reliance on petroleum diesel, coupled with growing concerns about environmental degradation, has propelled the exploration of renewable diesel fuel alternatives. This research study delved into the production of giant palm methyl ester through transesterification, employed potassium hydroxide as a catalyst. This alternative fuel was then tested in a single-cylinder, direct injection diesel engine commonly used in Nigeria's agricultural sector, where the demand for sustainable energy solutions is crucial. Pure vegetable oils encounter operational challenges in diesel engines due to their high viscosity, low calorific value, and polyunsaturated nature. Transesterification emerges as a more effective method to modify these properties. Comparisons between the physicochemical parameters of Giant palm methyl ester and convectional diesel fuel revealed significant differences. The calorific value of the produced biodiesel stood at 38,470 MJ/kg, slightly lower than pure diesel's 42.00 MJ/kg. Additionally, the kinematic viscosity of the biodiesel was measured at 10.9 mm2/s. The study also scrutinized engine performance using various biodiesel blends and compared them with conventional diesel. The findings demonstrated the viability of using biodiesel derived from giant palm seed oil in compression ignition engines as a practical alternative to diesel fuel. Lower blends, particularly B5 to B25, adhered closely to ASTM standards, signifying their acceptability. However, as biodiesel concentration increased, both break thermal efficiency and fuel consumption experienced an upward trend. The results showed that the use of biodiesel produced from giant palm seed oil in compression ignition engines is a viable alternative to diesel fuel.

Abstract

The tropical forest of West Africa is initially the first area where the oil palm was discovered before the 14th century. In particular, Nigeria was one of the places where this fruit was uncovered. Palm oil is ranked as the major vegetable oil in the world. In the 1960s, Nigeria was rated as the largest palm oil-producing and exporting country globally. However, the production was completely unsuccessful as a result of the government’s failure to formulate good policies, while the local consumption increases. Oil palm production in Malaysia became a contributing sector to the national economy. It alleviates poverty, provides employment, allocates resources, generates incomes, and leads to economic development. Due to good and sustainable palm oil policies in this sector, Malaysia achieved global recognition. This paper’s objective is to disclose the ineffective policies on palm oil in Nigeria and its sustainability in Malaysia. This paper is a qualitative design, it used primary and secondary methods. The primary method is based on a semi-structured interview, while the secondary method is based on documents. It adopted inductive thematic analysis for analysing interview data with the help of Atlas ti. This paper’s finding is the unsuccessful palm oil policies in Nigeria and the sustainable palm oil policies in Malaysia.In conclusion, there is a need for Nigeria, to learn from the Malaysian experience.

Abstract

Young oil palms produce many small fruit bunches. With age, bunch number (BN) declines but single bunch weight (BW) increases, more than the BN decline, raising its yield (FFB, or BN*BW). In a long-term trial in seasonal Southern Thailand, the age trend accounted for 81% of the variation in BN. With irrigation, BN increased 34%, and BW 5%, and the age trend accounted for 90% of BN variance. It was 98% for BW with/without irrigation. Besides age trends, the regular December – March dry season, despite irrigation, combined with intrinsic alternating sex cycles resulted in annual cycles in BN and BW. The BN cycle was more marked in younger palms whose rooting is shallower. The BW cycle persisted throughout, albeit at lower amplitude than BN. Female abortion after high production resulted in a BN semi-annual cycle, with peaks in Mar/Apr and Sep/Oct. A similar cycle for BW in older palms, with peaks in Dec - Feb and Jun-Aug, arose from fluctuating pollination. A three-year cycle in BN of unirrigated palms may be due to exhaustion/replenishment of carbohydrate reserves. Underripe harvesting, causing more yield in a month, and a dearth after, resulted in a 2-month cycle for BN.
