In line with this issues, a strategy to develop the POIC based international connectivity need to be done. This study aims to identify the actual conditions of POIC Indonesia, to determine the factors (internal and external) that influence the development of POIC, and to formulate priority strategy for developing POIC Indonesia. These are needed so that Indonesia can become a hub port of international trade especially in Asia. This research uses \"Diamonds\" Porter’s Model, gap analysis, and the Analytical Hierarchy Process (AHP). Based on the analysis connectivity, the main strategy that can be formulated in order to develop Indonesian palm oil industry cluster is infrastructure improvements. This strategy can be done if the government (the Ministry of economy, Ministry of industry and trade, Ministry of sea, PT PELINDO, and local government), private sector, academic, and the public is able to work together and integrated.","PeriodicalId":14324,"journal":{"name":"International Journal of Oil Palm","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72626919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The enhancement of bio grease characteristics can be performed by chemical synthesis. This research aimed to obtain best mole ratio of palm olein and H2O2 in the epoxidation process, and to analyze the physical characteristics of the bio grease products. This process used acetic acid and H2O2 with mole ratio variations of olein and H2O2 of 1: 3, 1: 6, and 1: 9. The mole ratio was selected based on the analysis of iodine and oxiran numbers, which was then processed into bio grease with the addition of calcium stearate and calcium acetate. Epoxidized olein with a mole ratio of olein and H2O2 of 1: 9 was selected because it achieved the highest average oxiran number (0.99), the lowest iodine number (33.09), and it was based on ANOVA and LSD tests. The higher the oxiran number, the more epoxide compounds produced. Low iodine number indicated low unsaturation in fatty acids. The peroxy acid used in the epoxidation process reacted with unsaturated compounds, so that the lower iodine number in the epoxidized olein produced more epoxide compounds.

Nowadays our understanding of the impacts of oil palm plantations is still based on the claim that oil palm plantations are established on primary forest land. The study aimed to estimate the impact of land cover changes, loss of biodiversity, and possible cohabitation between birds and butterflies based on baseline land type before oil palm plantation. The research was conducted at PT Tempirai Palm Resources, to be precise, in the baseline area (shrubs) and plantation areas planted with oil palm using direct and indirect observation methods. Based on research, it was known that land conversion to oil palm plantations caused changes in the number of species, and the diversity of birds and butterflies. The number of bird species in the baseline area was higher (S = 22 species, H ‘= 2.51) than in the plantation area. The number of butterfly species in the baseline area was less (0 species) than in the oil palm plantation area (5 species, H ‘= 1.56, Dmg = 2.23). In general, the increase in bird species’ biodiversity was higher (59.09%) compared to the loss. In contrast, the butterfly species was not lost. A cohabitation also occurred between birds and butterflies at the site. The study concluded that oil palm plantation not only have a negative impact but also a positive impact for biodiversity especially for bird and butterfly.","PeriodicalId":14324,"journal":{"name":"International Journal of Oil Palm","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84798858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is especially if implemented as a stand-alone facility and applied in a remote area. The purpose of this study is to evaluate technical feasibility and strategy in using pyrolysis stoves to produce biochar and generate electricity by ORC, simultaneously. This study combines various data obtained previously, which consists of pyrolysis stove design and performance test for simultaneous biochar production and thermal energy use, and ORC experiments for electricity generation. Those data then was used to analyze the technical feasibility of the simultaneous production of biochar and electricity generation using the excess heat from the pyrolysis stove. The integration of the pyrolysis stove with the ORC was conducted in a simulative study. The results showed that biochar produced using the pyrolysis stove has characteristics that are very supportive for use as a soil enhancer. Excess heat from the pyrolysis stove during the production of biochar can be used to fuel the ORC system to generate electricity. The optimum biochar yield and thermal efficiency of the ORC were found to be optimum at the stove's airflow rate of 0.034-0.035 kg/s. Accordingly, a combination of biochar production and electricity generation using the ORC system is considered to be technologically feasible to meet the sustainability requirement.","PeriodicalId":14324,"journal":{"name":"International Journal of Oil Palm","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85053731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Palm oil contains essential components in the form of triglycerides, mostly as fatty acids, namely palmitic acid, oleic, and linoleic. However, palm oil also contains minor phytonutrients, such as carotene, tocopherol, and tocotrienol. Palm oil has been widely used in the food and non-food industries. As a raw material in various products, palm oil undergoes a refinery process to remove unlike free fatty acids (FFA), odors, and colors (reddish to bright yellow). In this process, phytonutrients are degraded and damaged so that the content becomes very low. Phytonutrients in the CPO has not been fully utilized their benefits for human health. One of the palm oil products that contain high phytonutrient compounds is red palm oil. There are two types of red palm oil, namely virgin red palm oil (VRPO) and red palm oil derived from CPO (RPO). VRPO is produced from direct extraction of oil palm fruit, while RPO is produced from the neutralization of CPO and deodorization at low temperatures to reduce FFA levels. Both of these products contain high phytonutrients, such as carotene, tocopherol, and tocotrienol. This paper reviews several studies on the processing, characteristics, and potential use of red palm oil in food and non-food products. The application of red palm oil in margarine as a specific food product has the potential to be further studied.","PeriodicalId":14324,"journal":{"name":"International Journal of Oil Palm","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86134756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
