No full textHamzah et al, 2018. Empirical Study on the Pattern of Funding Sources for Rice Farming in South Sumatra. JLSO 7(2):196-203. The objective of the study was to identify the source and size of the financing portion of the rice farming from the loan and the terms and the interest rate charged. The interviews were conducted on 75 samples of rice farmers whose farming costs were partly derived from loans at three different land ecosystems in South Sumatra Province. The three types of ecosystems viz., tidal swamp land, technical irrigation, and swamp land were used in the study. The results showed that there were seven financing sources that farmers used for fulfill their production cost if they not enough capital. Middlemen was biggest source with a portion of 45.28% and their own costs of 43.52, the rest is relatively small comes from money lenders, families, rice milling units, cooperative and friends. The interest rate charged varies from 3% to 50% per planting season. The lowest interest rate on lending money was to cooperatives and middlemen. However, if farmers borrow from middlemen, they must sell their rice to them. The highest interest rate from money lenders is 50%. All loans were being paid at after harvested time. Only borrow to families and friends were not charged interest and other terms. Farmers were forced to use non-formal lending institutions because banks located far away and they were afraid to come to the bank. It is suggested to reduce the dependence of rice farmers on non-formal lending institutions through developing a more effective agricultural cooperative.      Â

JLSO 7(1):14-25. Palm oil commodities are one of the plantation sub-sector commodities that increase the income of farmers and the community, provide processing industry raw materials that create added value. The land cultivated by independent oil palm farmers consists of land land, tidal peatlands, coastal peatlands and coastal land. The difference in typology of this land will contribute to different production. The research aimed to analyze the oil palm production and the dominant factor affecting oil palm production according to the typology of land in Indragiri Hilir Riau Province. The data were analyzed using descriptive statistics and built multiple regression models with the dummy variable method of Ordinary Least Square (OLS). The results of the study showed that the production of oil palm cultivation on land is the highest compared to the typology of tidal peatland, coastal peat and coastal land. The dominant factors affecting palm oil production in Indragiri Hilir Regency were the amount of fertilizer use, labor, age of plants, herbicides and dummy typology of land. In order to obtain optimal production, this study recommended doing oil palm farming in accordance with the correct cultivation techniques in accordance with the characteristics of land typology. Besides that the use of balanced fertilizer (elements of N, P, and K) in accordance with the recommended needed to be applied

Binasawit Makmur. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands. 8(2):126-133.  A plant breeding program needs genetic diversity information of germplasm, but the source of genetic diversity of oil palm plants in Indonesia is very narrow. In order to increase genetic diversity, the introduction of germplasm from Cameroon was conducted. The purpose of this study was to obtain a useful molecular marker in order to get genetic diversity information in Elaeis guinensis germplasm materials from Cameroon at PT. Binasawit Makmur (BSM). This preliminary research has been done in 2013. In this study, 300 samples of Cameroon oil palm DNA from 99 accessions and 10 samples DNA BSM material were analyzed by 9 microsatellite markers (simple sequence repeat; SSR). The 9 SSR markers used were very informative and we obtained 93 alleles with an average of 10.33 alleles per locus. The value of polymorphism information content (PIC) was around 0.746-0.889. The total genetic diversity was relative high (HT = 0.814). The coordinate analysis showed no groups in both 99 accessions and BSM material. Based on phylogenetic analysis, 9 SSR markers could show the genetic diversity between the populations. To validate this fact, it needs further research using more molecular markers and samples
