PENGARUH TOPOGRAFI LAHAN TERHADAP PRODUKTIVITAS KELAPA SAWIT (Elaeis guineensis Jacq.) DI PT. DHARMA INTISAWIT NUGRAHA MUARA WAHAU KABUPATEN KUTAI TIMUR

Oil palm is one of the potential commodities whose cultivation trend began in 2003 in EastKalimantan which has the characteristics of hilly land. Oil palm itself is preferable to grow at analtitude of 400 m asl with a slope of up to 23% or at 12°.Therefore, this research is motivated todetermine the yield of oil palm plantations in certain land slope classifications. The study wasconducted on 2 afdeling which have different land classifications with an area of ± 14,000 ha.Thenfor comparison, it was taken through production data in 2019 with 2 treatments and 12 replications,which were processed using Analysis Of Variance (ANOVA) Two Way Anova. Primary data wereobtained through field observations, as well as soil sampling, which were analyzed directly for soilphysical properties and laboratory for chemical properties including pH H2O, Nitrogen (N),Phosphorus (P), Potassium (K) and Magnesium (Mg.). The results of the research on the effect ofslope on oil palm production by various methods indicate that the land slope factor does not have asignificant effect on oil palm productivity.

The purpose of this research is to find out what are the strengths, weaknesses, opportunities, and threats in the strategy of developing an oil palm agribusiness system (Elaeis Guineensis Jacq) in North Labuhan Batu Regency. The sampling research method used is purposive sampling method. The data used are primary data and secondary data. The analytical method used is descriptive quantitative method using SWOT analysis by analyzing the IFAS (Internal Factor Analysis Summary) and EFAS (External Factor Analysis Summary) factors. The results showed that using the SWOT diagram matrix, the oil palm agribusiness system development strategy was found in area II (Diversification Strategy). The situation in area II is a situation where farmers have to change their previous strategy, because the development of oil palm faces various threats but oil palm farmers still have internal strength. The focus of the strategy is to take action using strengths to take advantage of long-term opportunities by means of product and market diversification strategies.

The aims of this study to be determine the soil chemical properties and productivity of oil palm (Elaeis guineensis Jacq.) at different water levels on peatlands. The research was carried out in PT. Tabung Haji Indo Plantation (PT. THIP) Indragiri Hilir and the analys of soil chemical properties were conducted at the Laboratory of Soil Science, Faculty of Agriculture, Universitas Riau, Tampan District, Pekanbaru. This research was held started July to October 2017. This research conducted used survey method. The sampling location in this research are divided into 3 strata in 3 difference blocks and 3 samples that had been determined are named: TMA1 = 20- 40 cm, TMA2 = 41-60 cm and TMA3 => 60 cm carried out experimental used completely randomized design (CRD). There are three times repeatation treatments and 27 samples units in total. The observation data that obtained are analyzed statistically using analysis of variance (ANOVA). The results of variance analysis were continued by Duncan's multiple range test at the 5% level. The parameters of observation carried out include soil chemical properties: pH, C-organic, N-total, P-total, K-total, cation exchange capacity (CEC), saturation of bases (KB) and productivity of oil palm. The results showed that peatland with a water level of > 60 cm had soil pH, organic C, N-total, P-total, K-total, and CEC was higher than the water level of 20-40 cm and 41-60 cm, while KB at a depth of 20-40 cm had a higher KB value than the water level of 41-60 cm and > 60 cm.
