<![CDATA[Biodiesel has become favorable fuel for diesel fuel substitute to overcome the limited fossil fuel resources while facing the increasing of energy consumption. However, the use of FAME biodiesel is currently limited to mixing up to 30%. Therefore, it is necessary to consider other fuels as an alternative to diesel oil. One of them is by developing second generation biodiesel, which produced from the upgrading process of bio-oil as a result of pyrolysis. Bio-oil can be upgraded to fuel with range naphtha through two main processes that consisted of hydro-processing and catalytic cracking. Techno-economic studies on bio-oil production from oil palm biomass have been studied but the techno-economic studies up to upgraded bio-oil have not included. Before a techno-economic study was carried out, it was necessary to select the process technology route of upgrading bio-oil. Therefore, it is required to conduct a study of industry and the comparison of second generation biodiesel production technology from the upgrading of oil palm-based bio-oil to obtain an optimum process flow diagram. Process simulations were conducted using ChemCad software so that the mass balance and ratio of energy consumption was obtained. This work estimated the biofuel produced from palm residues collected from 19 units of a 60 tons/hour palm oil mill. The bio-oil input is 70.35 tons/hours with upgrading oil yield of 32.21%. The energy yield of this model is 35.7% while required 76.5 MMJ/hour of the energy. The energy required for this process can be provided by an integrated fuel upgrading facilities that connected with the palm bio-oil production plant could provide self-sustainable production facilities.]]>

<![CDATA[The development of the palm oil downstream industries is still limited eventhough various products can be made. The market acceptance becomes one of the important considerations. The research objective was to analyze the acceptance and initial price a new product of Virgin Red Palm Oil (VRPO), a kind of Red Palm Oil (RPO), one of the potential downstream palm oil products. A survey was conducted in Jakarta with African expatriate community as respondents. The samples of product VRPO with the brand of “Salmira” were given. After they tasted, they filled the questionnaire. The acceptance perception product was measured by likert scale, and initial price with the willingness to pay methods was investigated by open ended questions. The results analysed by average aprroached and optimum price used linear and logarithmic regression. This study found that product perception was very good especially in familliarity and reccomendation to buy. The new product was similar to the product available in their origin countries and when the product available, almost 90 % respondents would like to buy the product. Other results showed that packaging was preferred in 1 000 ml. The maximum willingnes to pay for 1 liter was IDR 150 000, and the minimum was IDR 20 000. The average price was IDR 70 370, and the optimum price with linear regression approached was IDR 70.809 and with the logarithmic regression approached was IDR 62.628. This study provides empirical evidence that the product is prospective eventhough it is still in the limited scope.The range willingness to pay also supports the decision maker to give the initial price.]]>

<![CDATA[One of the problems in smallholder oil palm plantations was the financing for replanting and loss of revenues during immature oil palm period. One alternative to the problem was the development of an adaptive plant system through intercropping crops planted among immature oil palm crops. The research was conducted in banjar seminai village, dayun subdistrict, siak regency, Riau Province on May to October 2017. The study used a factorial randomized block design with three replications. Annual crops treatment consists of corn, soybean, eggplant and chili. The results showed that there was positive response of oil palm height on intercropping systems. Corn intercropping plants increased the height of oil palm crops. The intercropping plants had no significant effect on the number of leaf midrib and the width of oil palm canopy. Monoculture oil palm crops without intercropping produced average emissions of 8.78 t CO2 ha-1yr-1. Oil palm intercrop with eggplant and soybean produces the highest CO2 emissions of 10.4 and 10.2 t CO2 ha-¹yr-¹, while oil palm in intercrop with chili produced the lowest CO2 emissions of 8.66 t CO2 ha-1yr-¹.]]>

<![CDATA[Recently, the growth of gelato outlets in Bali, Surabaya, Jakarta, and many cities in Indonesia hit 30-45% since 2013 to 2018. The gelato outlet has good margin at least 50% gross profit. However, the consumers need gelato not only good in taste but also it is not easy to melt. In modern world the formulations are based on premix of modified starch, sugar, emulsifier, stabilizers and milk solid nonfat. One of most popular brands of gelato premix is imported from Italy. In recent years, the use of palm oil in gelato is hardly reviewed. However, in ice cream business, palm oil is used widely. The fat blends of palm oil and palm kernel oil at PO/PKO (30/70; w w-1) was used, because the solid fat content (SFC) properties is similar to the SFC of butter oil. The level of this fat blend in gelato was varied from 5, 8, 10 and 12%. This research showed that the optimum fat blend addition in formula was found at 8%. The dripped test is used at 28 °C ambient temperature to measure heat stability. It was found that the more fat blend in gelato, the more stable the texture to heat shock and made the gelato easy to scoop as well. The cost in formulation with this 8% palm oil blend to gelato formulation is only 2.8%. Therefore, the palm oil blend in gelato formulation gives significant improvement melting and mouthfeel properties at insignificant cost addition.]]>

<![CDATA[Indonesia is the largest country in exporting crude palm oil (CPO) to the world market. However, the production capacity of the CPO downstream industries in Indonesia must continue to be increased, bearing in mind that Indonesia also imports CPO derivative products. In addition, oil palm plantations in Indonesia still face environmental and social issues, such as: deforestation, damage to peatlands, destruction of wildlife habitat (such as orang-utans), and land tenure conflicts. In this connection, Indonesia needs to continue to develop the CPO downstream industries that can increase added value and foreign exchange, absorb employment, and address environmental and social issues. Therefore we need appropriate government policies to support the development of the CPO downstream industries. The purposes of writing this paper were to analyze the factors that influence CPO demand by the CPO downstream industries (ie: palm cooking oil, margarine and soap industry) in Indonesia, and to evaluate the impact of facilitation policy that increasing production capacity of the CPO downstream industries on the CPO competitiveness of Indonesia-Malaysia and the palm cooking oil, margarine and soap competitiveness of Indonesia, as well as the welfare of oil palm farmers in the 2015-2017 period. This paper was part of the dissertation research results that using the CPO industry econometrics model. The dissertation model specification is a dynamic simultaneous equation consisting of 71 behavioral equations and 51 identities, while the model was estimated and simulated using the 2SLS and Newton methods. The results showed that the production capacity of the CPO downstream industries affected CPO demand by the CPO downstream industries. Furthermore, if the production capacity of CPO downstream industries (palm cooking oil, margarine, soap, biodiesel and others) increases, it will increase the Indonesian competitiveness in export CPO and its derivative and welfare of oil palm farmers in Indonesia.]]>
