Maize and soybean can be planted for intercropping on immature oil palm, however its financial and economycal aspects have not been widely studied. This study was aimed to analyze the financial and economic aspects of intercropping of maize and soybean on immature oil palm, level of land use efficiency, and comparison of efficiency between monolculture and intercropping system. The study located in Sorolangun Experimental Station, District of Sorolangun, Jambi. Methods used in the study were farming business analysis, Revenue Cost Ratio (RCR), Return on Investments (ROI), Land Equivalent Ratio (LER), and Land Equivalent Optimize Ratio (LOER). The results showed that maize had a profit level of Rp 9,676,564/ha/growing season, RCR 1.76; ROI 188.28% (three growing seasons per year), while soybean had a profit level of Rp 4,059,352/ha/growing season, RCR 1.51 and ROI 75.22% (three growing seasons per year). Based on these results, intercropping of maize and soybean on immature oil palm are economically and financially feasible. For the land use efficiency, corn LER value for corn and soybean was 0.95 and 0.85, respectively, showing that yield of maize and soybean from intercropping system (effective land area of 7,200 m2 per ha of oil palm area) was 95% and 85% when compared to monoculture system. The LOER value of corn and soybeans per ha was 1.32 and 1.18, respectively, which showed that corn and soybeans growing on intercropping system with immature oil palm were more efficient than monoculture system at the same size of land. Based on those comparative analysis of economic values, financial, and land use efficiency, corn was a better alternative crop for intercorpping on immature oil palm than soybean.

Seed moisture content is a crucial factor which will determine seed viability during storage and influence successful germination process. By that reason, ability to measure seed moisture content in precise is a basic need for seed producers. For plant species which produces large seeds such as oil palm, International Seed Testing Association (ISTA) demands that seed moisture content can be determined by using high or low constant oven temperature with seeds been sliced or crushed before the oven application. On the other hand, seed producers commonly use intact seeds to determine the parameters. Test results to compare between the two methods showed that low constant oven temperature generated higher seed moisture content than that of the high constant oven temperature method. In addition, moisture contents, which were generated by intact and crushed seeds, were not significantly different. Based on seed component, kernel contained higher moisture than shell, both by utilizing low and high constant oven temperature. Further research is needed due to a large range of shell thickness of oil palm seeds.

Flubendiamide is a new insecticide that highly selective against Lepidopteran insect pests. A research was conducted to determine the effects of flubendiamide application on the mortality of nettle caterpillar S. asigna, bagworm M. plana, and bunch moth T. rufivena on mature oil palm. In addition, we also investigated the effects of flubendiamide application on the activity of pollinating weevil E. kamerunicus. Flubendiamide was sprayed directly on the affected oil palm canopy or fruit bunches at the application rate of 0, 50, 100, 150, and 200 mL/ha. On the other hand, flubendiamide was sprayed directly on the anthesis male inflorescences at the dose of 150 mL/ha to study for its impacts against the activity of E. kamerunicus. The results showed that the mortality of each pest increased in line with the dose of application. Flubendiamide was effective against the leaf-eating caterpillar at the application rate of 150-200 mL/ha whilst the application of 200 mL/ha flubendiamide was required for controlling the bunch moth. Moreover, the application of flubendiamide had no adverse effects on the activity and the development of E. kamerunicus on male inflorescences.

To identify flowering development phases that most determines oil palm yield in relation to water dynamics, a research had been conducted at Indonesian Oil Palm Research Institute (IOPRI) experimental garden in Tandun, Riau. The variables observed were water parameters including rainfall, groundwater level, soil water content, and the rate of increase in capillary water at 0 – 200 cm soil depth. Rrelationship between water parameters and oil palm yield was analyzed using correlation statistics and multiple linear regression models. Analysis of multiple linear models was performed using stepwise regression techniques to select the most powerful parameters determining the relationship between independent and non-independent variables. MATLAB R2017b software was used for data processing. The study showed that phases of flower bunch development at certain time prior physiological maturity determined monthly oil palm yield. Critical phases affected oil palm yield were formation of flower crown, sex differentiation, appearence of flower buds, and ripening of fruit bunches. Compared to other flower developmental phases, the phase of sex differentiation of flowers that occurred 20 months before the fruit bunches were physiologically mature was the most critical phase in determining monthly yield of oil palm.

Indonesia adalah salah satu negara produsen dan eksportir minyak kelapa sawit terbesar di dunia. Adanya kebijakan hilirisasi sawit menyebabkan Indonesia lebih banyak mengekspor produk turunan dalam bentuk Refined Palm Oil (RPO) dibandingkan Crude Palm Oil (CPO). Indonesia juga menghadapi kompetisi dengan Malaysia sebagai eksportir RPO di beberapa negara importir seperti China, India, Rusia dan Amerika Serikat. Penelitian ini bertujuan untuk menganalisis kompetisi antara Indonesia dan Malaysia di beberapa pasar negara importir RPO. Model yang digunakan adalah Almost Ideal Demand System (AIDS). Berdasarkan hasil penelitian menunjukkan harga RPO Indonesia lebih elastis di pasar India dan Amerika Serikat, sedangkan harga RPO Malaysia lebih elastis di pasar Rusia. Meskipun RPO asal Indonesia dan Malaysia saling bersubstitusi, tetapi posisi Indonesia lebih diuntungkan dibandingkan Malaysia jika negara-negara importir tersebut meningkatkan pengeluaran untuk impor RPO karena akan meningkatkan share impor dari Indonesia.

Oil palm smallholder currently are more than 25 years old and have to be replanted. However, many smallholders have facing difficulties in replanting especially related to investment and loss of income during the period of immatature. Palm trunks from replanted plants have potential economic value by utilizing sap obtained by tapping inflorescences of oil palm to make brown sugar. This study aims to assess the economic value of oil palm brown sugar as a potential financing of oil palm plantation peremajaan. The study was conducted in the village of Lau Tador, Sei Suka District, Batu Baral Regency North Sumatra. The research method used was on farm participatory research survey and focus group discussions were carried out farm business analysis. Research shows that oil palm trunks have considerable economic value potential. The economic value of 1 palm trunk for oil palm brown sugar (not yet processed/straightened before being cut) is IDR. 15,813 (IDR 1,897,500 per ha). Whereas if processed into oil palm brown sugar has a potential net income per ha of IDR 18,421,500 to IDR 22,866,325 with financial analysis carried out. This potential can help smallholders living costs and up keep costs as long as immatature. To optimize the economic potential of production, it is carried out on a wide scale through the development of farmer groups or cooperatives. Through cooperatives will be managed in an organized manner including funding, technical, production, and marketing. The utilization oil palm brown sugar can be used as one of the activities in the oil palm smallholder replanting program (PSR) which is the government's main program.

Elaeidobius kamerunicus is the main pollinating insect in oil palm plantations in Indonesia which influences the oil palm fruit set. Theoil palm (Elaeis guineensis) male inflorescence is the only one of their breeding site. The application of insecticides, especially those directly to the male inflorescence, can affect the activity and breeding of pollinator insects. Various insecticides include Deltamethrin (2 mL/L), Lamda Sihalotrin (2 mL/L), Dimehipo (2 mL/L), Asefat (1.5 g/L), Fipronil (2.5 mL/L), Chlorantraniliprol (1 mL/L), Flubendiamide (0.5 mL/L) and B. Thuringiensis (2 mL/L) have been tested on E. kamerunicus weevils by in vivo trial and on anthesising male inflorescence at different levels of bloom (25 %, 50%, 75% and 100%) in the field. The weevils mortality observations were carried out for 5 days after the insecticides application in the laboratory while observations in the field included the number of weevils visit before and after insecticide application until the end of the male flower anthesis and the number of new emerged weevil in each spikelet after 21 days of incubation. The results showed that the chemical insecticides i.e. Deltametrin, Lamda Sihalotrin, Dimehipo, Asefat, and Fipronil were killed the weevil, affecting the weevil visit on anthesising male inflorescence 1-3 days later, and decreasing the number of new emerged weevil from each spikelet of male inflorescence after incubation for 21 days. Meanwhile, the treatment of Chlorantraniliprole and Flubendiamide and B. thuringiensis did not affect the development of E. kamerunicus both in the laboratory and in the field so that they were safe for oil palm pollinating naturally.

Oil palm plantations on tidal swamp land are increasing with the potential of land reach 20.1 million hectares due to unavailable mineral land which can be used. The limitation of optimal land for oil palm in Indonesia is currently a factor that encourages the use of sub-optimal land, one of which is tidal land. The use of tidal land has certain constraints such as soil acidity, low soil fertility, poor soil drainage conditions, lack of water and increased pyrite oxidation during dry periods which have a negative impact on oil palm growth and productivity. This preliminary study examines the effects of existing water governance to get the right solution and can be applied in the future. Modeling on HEC-RAS 4.1 software produces a simulation of the physical phenomena of channels in the land. The overall results show that the condition of the water governance system in the observation block is not optimal so that the inundated areas range from 65% due to the lack of good water management systems such as the drainage of the canals, the lack of water buildings and even the sluices so that in an uncontrolled area. This obstacle can be overcome by improving water management, such as canal washing, construction of water buildings, including culverts, bridges, crop harvesting, stoplogs and sluice gates. Water management system plays an important role in controlling water in the garden area so that in the rainy season, water can be channeled to outlets and in the dry season, water can survive in the garden area.This study is expected to be a reference in improving the water management system in that location.

Oil palm (Elaeis guineensis Jacq.) is a plantation commodity that has an important role in various aspects of life in Indonesia, especially the domestic economy. This is supported by the increasing demand for world palm oil for food needs (edible oil), industrial (oleochemical), and alternative energy sources based on biodiesel. The development of the palm oil industry requires several efforts to achieve increased national productivity, one of which is the utilization of quality seeds supported by the availability of genetic resources (germplasm) that have a high level of genetic diversity. Efforts that can be made for the development of oil palm in Indonesia is through the characterization of oil palm intoduction from abroad. Considering this, further research on genetic distance analysis of palm oil accession introduced from Cameroon is based on morphological characters to produce parent elders that can produce heterosis properties. Research conducted at Seed Garden of Adolina PTPN IV and laboratory analysis of plant material of Palm Oil Research Center located on Jl. Brigjen Katamso No. 5, Medan, North Sumatera, which lasted from December 2017 to February 2018. Single observations were made on 47 accession palm oil from Cameroon planted on December 2010 and ten trees from PPKS 540 variety for compare. Data analysis used was a description of the plant to know the character of plant morphology as well as genetic distance analysis. Analysis of genetic distance using PCA analysis and cluster analysis. The results obtained are based on the results of PCA (Principal Component Analysis) reduce the observed character into six major components that have eigen value > 1 and able to explain the material diversity tested for 73.8%. Based on the cluster analysis obtained the genetic distance of 47 accessions of palm oil from Cameroon by 57%. It can be concluded that, when the genetic distance between accessions is further away, the larger the genetic variability between the observed characters. If the genetic diversity is wider the greater the chance for successful selection in increasing the desired gene frequency.
