Elaeidobius Kamerunicus

Oil palm plants are a type of plant that undergoes pollination through the mediation of polinator agents because of the position of male flowers and female flowers in separate flowers. Elaeidobius kamerunicus is an effective type of pollinating insect in oil palm plants. This research was conducted at this research carried out on oil palm plantations of PT. Karya Tanah Subur (KTS) of West Aceh Regency. This research was conducted from February to March 2018. The collection of insect samples using the Purpose Sample method (sample determined), which uses 4 blocks of plants with different age groups of 4,5,6 and 7 years, respectively. Each age group on each block uses 6 sample plants. The results show the abundance of pollinator insects not influenced by plant age and altitude, but are influenced by the time of sampling. Domination index of palm oil pollinator insect simpons at PT. Karya Tanah Subur (KTS) is worth 0.9280 which means high evenness. The abundance of oil palm pollinators affects the average production of oil palm at PT. Karya Tanah Subur (KTS) Keywords: oil palm, Elaeidobius kamerunicus, pollinator

Planting Material

Various factors influence palm oil production, including planting material, environment (climate and soil), and cultivation management. The environment occupies a crucial position that can affect crop production potential even with optimal cultivation management. Unfavorable climatic conditions, for instance, drought, can cause water deficit, which has implications for crop productivity. This paper aims to get a comparative study for the effect of water deficit on the inflorescence period, namely the sex determination phase (29 months before harvesting) and floral abortion (10 months before harvesting). The research was carried out on oil palm plantations on peatland in Riau, Indonesia, with the characteristic annual rainfall of 2000 mm/ year. This study employs a simple regression analysis on panel data of five years and two estates for data analysis. The result highlights that the increase of a 100 mm water deficit on oil palm peatland plantation impacts the decrease in productivity by 6% in the sex determination phase. In contrast, in the floral abortion phase, the decline in productivity is more significant, namely 7%. The analysis also indicated that the research deficit had more impact on the bunch number than the bunch weight.

Initial Seeding

       Along with the increasing demand for palm oil has the world's population, it is necessary to think about efforts to increase the quality and quantity of palm oil production. One of the factors such as planting material in the form of seeds, it is necessary to act technical culture or good seed treatment. Oil palm seedlings can be done in two stages: initial seeding (prenursery) and moved at the age of 2.5-3 months when they fulfill the criteria nursery ready to move to the main (main nursery). This study aims to (i) determine the speed of growth of oil palm seeds and, (ii) obtain the best type of soil for growing speed of oil palm seeds in two places making swampy marshland. The research was conducted in the Pangkalan Sari Village, Sungai Pandan Sub-district, Hulu Sungai Utara Regency in July-August 2013, using a completely randomized design (CRD) with a single factor. Factors studied were two lebak wetland of origin of uptake (T) as much as two levels and repeated nine times. The results showed that the two treatments had no effect lebak wetlands on many shoots observation variables age 14 and 28 days after seeding(DAS), the amount of leafage of 14 DAS, seedling height 14 DAS, and significant observations on many variables shoots the age of 42 DAS, number of leaves age 28 and 42 DAS, and a very significant effect on seedling height observation variables age 28 and 42 DAS.

Water Ratio

Natural gas is a source of energy that comes from the earth which is depleting every day, an alternative source of energy is needed and one of the sources comes from biogas. There is an abundance of empty fruit bunch (EFB) that comes from palm oil plantation that can become a substrate for biogas production. A methodology of fermentation based on Verein Deutscher Ingenieure was used to utilize EFB as a substrate to produce biogas using biogas sludge and wastewater sludge as inoculum in wet fermentation process under mesophilic condition. Another optimization was done by adding a different water ratio to the inoculum mixture. In 20 days, an average of 6gr from 150gr of total EFB used in each sample was consumed by the microbes. The best result from 20 days of experiment with both biogas sludge and wastewater sludge as inoculum were the one added with 150gr of water that produced 2910ml and 2185ml of gas respectively. The highest CH 4 produced achieved from biogas sludge and wastewater sludge with an addition of 150gr of water to the inoculum were 27% and 22% CH 4 respectively. This shows that biogas sludge is better in term of volume of gas that is produced and CH percentage.
