Abstract

Paddy production at Sedau Village are improving caused by land characteristics. Then the carrying capacity would be counted by it correlation between the amount population and paddy productivity each year. The object of the research are to identify soil characteristics, determine cluster type and the carrying capacity of rice fileds in Sedau Village. The research method is soil survey, soil sample analysis, multivariate regression analysis, cluster analysis and the analysis of the carrying capacity. The results showed, variables affecting rice production were Bulk Density, Permeability, P-available and K-exchangeable. If Soil Bulk Density and Permeability are increased, so the paddy production will decrease. If P-available and K-exchangeable are increasing, so the paddy production will increas too. Following the formula: Y=1.605 "“ 0.783X1 "“ 0.367X3 + 0.005X11 + 9.206X12 + error. The research site consisting of 6 Land Mapping Units (LMU) is divided into 3 clusters. Cluster 1 consisting of LMU 3 and LMU 6, Cluster 2 consisting of LMU 2, 4 and 5, Cluster 3 only contains LMU 1. All clusters are classified as carrying capacity Class III, that means rice fields in each clusters has not been able to food self-sufficiency.

Abstract

The relationship of biological properties of peat with oil palm basal stem rot (BSR) caused by Ganoderma.  Indonesia as the largest palm oil producer in the world, has the large percentage of oil palm on peatland. 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. These results indicate that peatland vegetation management by maintaining the diversity of vegetation around oil palm can help reduce Ganoderma attacks.
