Replanting Model of Palm Oil with Paludiculture System on Peatland in South Kalimantan (Soil Physical Characteristics and Optimize Analysis)

Abstract

Efforts to accelerate the development of smallholder plantations in the plantation revitalization program are carried out through expansion, rejuvenation and rehabilitation of estate crops. however, the problem faced by farmers today is the fear of farmers losing their livelihoods if their oil palms are rejuvenated. On the other hand, peat ecosystem is an ecosystem that is very important role in maintaining environmental sustainability, especially related to the issue of global warming. one way that can be taken to prevent widespread damage on peatlands and to prevent future loss of community livelihoods by applying paludiculture planted on peatlands. the paludikulture model is a multiple cropping system in peatlands that can be adopted in oil palm areas. The results showed that the status of soil fertility in the area of oil palm rejuvenation has a relatively better soil fertility status when compared to mineral material, which has a range of status from low to moderate. Whereas mineral soil material has a low soil fertility status. This is concluded, although the cation exchange capacity of this soil sample is classified as high, but the cause of the low soil is the P-total, K-total and C-organic content is classified as very low to low. The results of the analysis of farmer optimization show that the optimal cropping pattern of vegetable farmers is commodity long beans + cucumbers. With farm income at optimal conditions is Rp 4,289,944 per year or Rp 18,619,548 per hectare per year.
