Abstract

The development of oil palm plantations in East Kalimantan can encourage the improvement of the regional economy and the people's economy.  The interest of farmers to cultivate oil palm plantations is quite large, however, the production results are not in line with expectations.  The purpose of this study is to determine the differences in productivity and income between independent smallholders, plasma, and large private companies. This research is a qualitative descriptive study referring to quantitative and comparative studies.  It was conducted in 5 districts namely, Kutai Kartanegara, Kutai Timur, Penajam Paser Utara, Paser, and Berau in the largest oil palm plantation area in East Kalimantan. The results showed that (1) the productivity of oil palm plantations on large private- and plasma- plantations continued to increase until the age of more than 10 years, while in smallholder self-help plantations the highest productivity was at the age of 9 years, after that there was a decrease in productivity; and (2) the income of large private plantations and plasma plantations continues to increase until the age of the plant is > 10 years, while in smallholder plantations the highest income occurs at the age of 9 years.

Abstract

The objectives of the study of land degradation status for biomass production are: (1) to collect data and information on initial soil conditions on land use for biomass production; (2) to determine land damage status for biomass production on land use for biomass production; and (3) mapping the status of land damage in Marangkayu sub-District, Kutai Kartanegara Regency.The research was carried out for 4 months, the research location was in Semangkok and Sebuntal Villages, Marang Kayu sub District, Kutai Kartanegara Regency. Research activities carried out include: preparation, field observations, soil sampling, soil sample preparation, soil analysis in the laboratory, data processing, and interpretation, and reporting. The results showed that: (1) Land with undamaged status was found in wetlands at Semangkok 4 location; (2) Dry land with mild damage status occurred at Semangkok 5, Semangkok 6, Sebuntal 5, and Sebuntal 6 locations, while wetlands with mild damage status occurred at Semangkok 1, Semangkok 2, Semangkok 3, Sebuntal 1 and Sebuntal 2 locations; (3) Wetlands with moderate damage occurred at Sebuntal 3 and Sebuntal 4 locations, not dry lands with moderate and heavy damage; and (4) Land damage for biomass production mostly occurs in dry land caused by damage to the basic properties of the soil which includes soil erosion, fraction composition, and soil pH, while in wetlands that are damaged with damaged soil properties are soil pH. and the depth of the pyrite layer.
