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 extent to which oil palm has contributed to deforestation of primary forests is still an intensive debate in public space. Even though the term deforestation and the results of the study and study are still "debatable" and have not been scientifically valid, they have had a very debilitating effect and detrimental to Indonesia's position in global trade because it is considered responsible for the destruction of primary natural forests in the Southeast Asia region. Therefore, since 2015, research has been carried out on the origin of status, history of land use, land-cover and biodiversity in several oil palm plantations in 6 provinces (Riau, North Sumatra, South Sumatra, Central Kalimantan, West Kalimantan and West Sulawesi). The results of the search for the origins of the status of oil palm plantations (according to the RTRWP) show that 98.56% of the candidates for oil palm plantation areas are "not forested", namely: APL (54.93%), Plantation and Agriculture (42.19%). Furthermore, the results of interpretation of Landsat imagery on the condition of vegetation cover at 1 year before being made into oil palm plantations indicate that the type of land cover is no longer in the form of primary forest, but already in the form of shrubs and bare-land or rubber-plantation (68,91%). Likewise with the results of the search history of land use (see slide) where 71.29% of the land under study is the land of ex-community gardens, fields, transmigration land, or ex-HGU of other companies. While the rest (28.71%) is ex-HPH land. Referring to the juridical definition of "deforestation", this data shows that oil palm plantation land which is the location of the study "is not the result of deforestation". Referring to both the juridical definition and the FAO/World Bank definition of "deforestation", this data shows that oil palm plantation land which is the location of the study "is not a direct cause of primary deforestation".
Verification of AOCS Cd 29a-13: 2013 Method for 3-Chloropropane-1.2-Diol Esters and Glycidol Esters Analysis in Palm Oil Zada Agna Talitha; Nuri Andarwulan; Didah Nur Faridah

Abstract

Fatty acid esters of 3-Chloropropane-1,2-diol (3-MCPD) and Glycidol were contaminants in fat-rich foods such as palm oil. These contaminants have received serious concern since they may cause cancer in humans. Several methods have been developed to analyze 3-MCPDEs and GEs especially in refined palm oil, including AOCS Cd 29a-13 2013 with aid of GC-MS. Principally, it involves transesterification promoted by H2SO4 in MeOH, then derivatized using PBA (Phenylboronic Acid). The verification was required before applying this method in laboratory. The instrument performance analysis showed that linearity response (r) reaching up to 0.997 for 3-MCPD and 0.998 for Glycidol, determined from a linear regression using internal standards and external standards at the range of 0.3-9.3 mg/kg (3-MCPD) and 0.6-21.3 mg/kg(Glycidol). The precision of retention time in 3-MCPD and Glycidol demonstrated satisfying results, RSD = 0,03% (3-MCPD-d5), RSD = 0,02% (3-MCPD), RSD = 0.03% (Gly-d5) and RSD = 0.03% (Glycidol). The LoD was observed at 0.037 mg/kg (3-MCPD) and 0.072 mg/kg (Glycidol), while the LoQ was found at 0.123 mg/kg (3-MCPD) and 0.241 mg/kg (Glycidol). The verification method showed that recovery percentage for 3-MCPD and Glycidol was 92.19% and 88.38%. The precision of retention time results, RSD = 0.05% (3-MCPD) and RSD = 0.04% (Glycidol) and the precision of concentration results showing RSD Analysis value?<2/3 RSD Horwitz. Within the RSD analysis of lab reproducibility was obtained at 3.42% (3-MCPD) and 3.64% (Gly) less than the value of RSDh. This method also have a good specificity. Based on the verification results, this method meets all requirements and therefore can be applied for analysis in the laboratory.

Abstract

Ganoderma philippii is the causal agent of root rot disease causing economic losses to Acacia plantations. In an effort to control the Ganoderma root-rot disease, we isolated and screened white-rot fungi as biological control agents. We collected 107 samples from forestry plantations in Riau Province. The fungi were isolated from rotten wood including trunks and twigs, and fruiting bodies. Out of the 107 samples, 28 from rotten woods and 51 from fruiting bodies were successfully isolated. Screening of the isolated fungi was done on wood block, wood disc, and wood-powder-containing agar. Eleven isolates showed fast growth on wood block and in subsequent second screening in dual culture on wood disc, three isolates showed fast growth and were capable of overgrowing G. philippii. The third screening was to examine quantitative growth rate of selected fungal isolates on malt extract agar wood powder (MEA-WP) two isolates were selected. These two isolates have shown potential as biological control agents of the root-rot pathogen, G. philippii.
