Smallholder’s plantations represent 44% of oil palm in Indonesia, and they were known to have agronomic performance much lower than Estate ones. So there is large room for increasing the yield with sustainable cropping system.  To better understand the heterogeneity of smallholder’s plantations, an agricultural diagnosis has been implemented in a specific place, Riau Province of Sumatra.  This study led to well characterize the dynamics of plantation in the region and the diversity of rationalities.  Among eight existing types of smallholding plots, there were only three types with yield hardly lower than those of the estate plantations.  This reinforced the interest to implement diagnosis through the nutritional status of palms using data from foliar diagnosis and soil analysis.  Key words : dynamic of plantation, palm oil, smallholders, Sumatra

ABSTRACTIndonesia will continue to face a discrimination of palm commodity in European Union in the next decade. The challenge the European black campaign against palm oil is not easy to overcome. Most of European people have a bad perception about palm oil. The issue of palm oil is not only about the forestation, but also it is influenced by bad perception on health and social impact. It is a time for Indonesian diplomacy to make a strategy to resolve this issue by improving public diplomacy through lobbying, corporate diplomacy and identification of stakeholders. Although in the European Parliament statement does not mention the elimination of palm oil, discrimination against palm oil will continue in the trilogy. Palm oil must face accusations from various interested parties such as NGOs and members of parliament who have relations with farmers in Europe. They have a strategy to phase out using palm oil for biofuels. The issue of palm oil is not only about a battle of the vegetable industry anymore, but it is more about politics to defend other vegetable oil in the market by disseminating any kind issues related to oil palm plantation. It must be deal with the total diplomacy taken by all stakeholders in Indonesia and in Europe.           Key words: oil palm, public diplomacy, biofuels, European Parliament

The purpose of this paper is to create an expert system to detect oil palm plant diseases in order to help farmers / companies in providing accurate information about the diseases of oil palm plants and how to overcome them and to help reduce the risk of decreasing palm oil production. This system is designed to mimic the expertise of an expert who is able to detect diseases that attack oil palm plants. The method used is forward chaining that is starting from a set of data and proving a fact by describing the level of confidence and uncertainty found in a hypothesis. The results of this study are to diagnose diseases of oil palm plants and their computerization using web programming languages.

Malaysia is the second largest palm oil producer and exporter globally. When crude palm oil is produced in both plantations and oil processing mills, a large amount of oil palm empty fruit bunch (OPEFB) is simultaneously produced as a waste product. Here, we describe the preparation of hydrolysate from OPEFB. After OPEFB was hydrothermally treated at 180–200 °C, the resultant liquid phase was subjected to high-performance liquid chromatography analysis, while the solid phase was used for acidic and enzymatic hydrolysis. Hemicellulose yield from the acid-treated solid phase decreased from 153 mg/g-OPEFB to 27.5 mg/g-OPEFB by increasing the hydrothermal treatment temperature from 180 to 200 °C. Glucose yield from the enzyme-treated solid phase obtained after hydrothermal treatment at 200 °C was the highest (234 ± 1.90 mg/g-OPEFB, 61.7% production efficiency). In contrast, xylose, mannose, galactose, and arabinose yields in the hydrolysate prepared from the solid phase hydrothermally treated at 200 °C were the lowest. Thus, we concluded that the optimum temperature for hydrothermal pretreatment was 200 °C, which was caused by the low hemicellulose yield. Based on these results, we have established an effective method for preparing OPEFB hydrolysates with high glucose content.

Although companies have many direct and indirect impacts on the lives of children, discussion of the responsibility of business to respect the rights of children has primarily focused on child labor. Using UNICEF’s Children’s Rights and Business Principles as a framework for our analysis, we considered the activities of oil palm plantation companies operating in Indonesia. Our data come from key informant interviews and reflection on two programs established to promote respect for children’s rights in the Indonesian palm oil industry: one by Pusat Kajian Perlindungan Anak (PKPA) (Center for Child Study and Protection); and one by the Roundtable on Sustainable Palm Oil (RSPO) in conjunction with UNICEF. We considered: how plantation company activities impacted children’s lives; how companies demonstrated respect for children’s rights; and how observance of children’s rights can be improved. We discuss four problematic issues: getting company commitments to children’s rights into policy and practice; having a strong business case for respecting human rights and children’s rights; contradictory objectives within companies; and complexities around children in the workplace. We argue that a children’s rights based approach should be applied to the activities of all organizations. This children’s rights lens is needed to overcome the invisibility of children in society and industry, and to address the root causes of human rights harms. We note that respecting children’s rights will likely contribute to getting a social license to operate and grow.

A sudden pH drops always inhibits the anaerobic digestion (AD) reactor for biogas production from palm oil mill effluent (POME). The pH adjustment of POME by oil palm ash addition and the biogas effluent recycling effect on the preventing of pH drop and change of the archaea community was investigated. The pH adjustment of POME to 7.5 increased the methane yield two times more than raw POME (pH 4.3). The optimal dose for pH adjustment by oil palm ash addition was 5% w/v with a methane yield of 440 mL-CH4/gVS. The optimal dose for pH adjustment by biogas effluent recycling was 20% v/v with a methane yield of 351 mL-CH4/gVS. Methane production from POME in a continuous reactor with pH adjustment by 5% w/v oil palm ash and 20% v/v biogas effluent recycling was 19.1 ± 0.25 and 13.8 ± 0.3 m3 CH4/m3-POME, respectively. The pH adjustment by oil palm ash enhanced methane production for the long-term operation with the stability of pH, alkalinity, and archaea community. Oil palm ash increased the number of Methanosarcina mazei and Methanothermobacter defluvii. Oil palm ash is a cost-effective alkali material as a source of buffer and trace metals for preventing the pH drop and the increased methanogen population in the AD process.

Palm oil industry produces huge amount of oil palm decanter cake (OPDC). Currently it is not yet commercialized however due to its characteristics, it can be used to produce oil palm decanter cake natural polymer composite (OPDC-NPC). NPC is a type of material made by combining natural fiber with polymer. Therefore the objective of this paper is to produce NPC from OPDC and then determine its mechanical and physical properties such as elasticity, stiffness, tensile strength and water absorption rate. The OPDC samples were collected from Felda Trolak Palm Oil Mill. Prior to NPC development, the oil was removed from OPDC using hexane soxhlet extraction method. OPDC-NPC was fabricated using molding method where the mixture of 95% polypropylene (PP) and 5% OPDC were mixed using twin-screw extruder. The results showed that OPDC-NPC has an elasticity of 2231 MPa, stiffness of 30 MPa, tensile strength of 32 MPa and water absorption rate of 0.16 % which was slightly better with the other types of fibers.
