The serious problems of cultivating oil palm on peatland is the presence of BSR disease caused by Ganoderma. There are no effective methods to control the spread of this disease. Biological control is an environmentally friendly alternative method focus, but on peatland, the development of this method is constrained by lack of information about the effect of biological environmental factors. This study aims to determine the effect of the biological propertiess  of peat on the intensity of Ganoderma attacks on oil palm. The relationship between the intensity of Ganoderma attacks and biological properties of peat was carried out by correlation test. The correlation analysis showed that the biological properties  of peat has not correlated with the Ganoderma attacks, except Summed Dominant Ratio of vegetation which tends to positively correlate to the number of Ganoderma antagonists.

The development of oil palm plantations in Sintang Regency has been rapid in the last decade. Sintang Regency has declared to implement sustainable oil palm plantations while still considering environmental sustainability aspects. Management of the oil palm trading system to be effective and efficient is the main indicator of sustainable oil palm plantations. Gap analysis in the trading system is an important effort as a basis for making various policies. The Gap Analysis of Oil Palm Supply Chain in the Ketungau Landscape, Sintang Regency, West Kalimantan Province is aimed to identify the gaps that occur between levels of oil palm trading actors in the Ketungau Landscape, Sintang Regency. The analysis is carried out using a comparison method between the current reality and the perspectives expected by the stakeholders. The results of the analysis show that in the palm oil supply chain in the Ketungau Landscape, gaps still occur at every level of the supply chain. The gap between independent oil palm smallholders and the government is the lack of assistance programs and capacity building for smallholders and improving the quality of infrastructure. The gap between the government and companies is that the government's supervision of palm oil business actors is still not maximal. The gap between independent smallholders and companies is that there is still no understanding between the two parties, especially regarding the quality criteria for FFB.

Independent small holder oil palm plantations in Kubu Raya Regency are facing a bigger problem because most of the plantations are on peatlands, therefore efforts are needed to help these farmers.

The results showed that most of the independent small holder oil palm farmers in Kubu Raya Regency running their business only as a side job so that the management is not optimal.
