Abstract

The purpose of this study was to examine the chemical characteristics of the soil on cocoa fields ex PT. Cokran in Abreso village, Ransiki district, South Manokwari regency. This research was a descriptive research with survey method and laboratory analysis. The variables observed in this study were the chemical properties of the soil in cocoa fields, which included four (4) locations on the coast, riverbanks, alluvial plains, and mountain edges. The results showed that the chemical status of the soil at the four cocoa fields had Cation Exchange Capacity (CEC) in the range of 31.27 – 44.18 cmol/kg, with high to very high categories. P-available ranged from 6.62 to 11.80 ppm which was classified as low to very low. Base cations (Ca2+, Mg2+, K+, Na+) had a high to very high category, Base Saturation (KB) was also quite high with a range of 96% - 100%. Soil chemical characteristics in these four (4) areas were vary, but quite suitable for the development of cocoa plantations especially for land in the Alluvial Plain area with an area of ​​416 Ha.

Abstract

This study aimed to determine the carrying capacity of agricultural land in providing food to meet the needs of the population in Susweni Village, East Manokwari District. This study used the method of determining or comparing the carrying capacity of land by comparing the availability and needs of land. The results of the calculation of carrying capacity using the concept of calculation according to the regulation of the Minister of the Environment No. 17 of 2009 showed that the Susweni Village, East Manokwari District had a land carrying capacity status that was in deficit for the population living in Susweni Village, East Manokwari District. The availability of land of 78.47 ha and the need for land is 302,084 ha. Therefore, the need for land in the Susweni village is greater than the availability of land in the Susweni village. The deficit carrying capacity of the land in Susweni Village, East Manokwari District is strongly influenced by the population which continues to increase every year.
