Abstract

Land is a natural resource with a limited number so that the utilization of this resource should consider its ability to be able to produce sustainably. Inappropriate use may result in land degradation as indicated by the amount of erosion. This study aims to (1) evaluate the land use capability (LUC) classes and their conformity with the actual land use, (2) determine the impact of mismatches between the LUC classes and actual land use on erosion. Study was conducted in Tapan and Ngunut I Sub-Sub-watershed, Karanganyar District, Central Java. Universal Soil Loss Equation (USLE) was used to predict the potential erosion on the area while modified FAO method was used to analyze LUC. The results showed that the percentage of disagreement between LUC class and with actual land use in Tapan was 23% while in Ngunut was only 0.02%. The percentages of those disagreements have no effect on the magnitude of the annual erosion. Annual erosion in Tapan (15.12 tonnes / ha) is still smaller than in Ngunut I (25.63 tonnes / ha). Composition of land cover types and land management affect the amount of erosion. Cultivation of crops at dry land and land tillage during growing season in accordance with the rainy season has great contribution on erosion. Keywords : Unsuitability, land covers, LUC, erosion

Abstract

Plant litter is the major source of organic matter in the forest floor and litter decomposition plays an important role in the organic matter and nutrient entry to the soil. The decomposition rate is strongly influenced by climatic conditions and initial chemical composition of the litter. Litter in the rehabilitated forest area of Wanagama 1 Education Forest is dominated by Gamal (Gliricidia sepium) litter which isconsisted of leaves, twigs and fruit pods. This study assessedthe decomposition rate of leaf, twig and fruit podlitter of Gamal in compartment 5 and 6 of Wanagama 1 Education Forest. To assess effect of season, the research was conducted in dry season (August to November 2012) and in rainy season (from January to March 2013). The results showed that the decomposition rates of leaf, twig and fruit pod litter of Gamal in dry season were moderate with k (decomposition index) = 0.0074 – 0.0065, slow (k = 0.0043 – 0.0040), andslow (k = 0.0031 – 0.0026), respectively.In the rainy season, the decomposition process was faster with decomposition rates were high (k = 0.0132 – 0.0161), moderate (k = 0.0073 – 0.0065) and moderate (k = 0.0055 – 0.0063), respectively. There was no effect of compartments which differed in the stand density. Keywords : Decomposition Rate, Kind of Litter, Gamal (Gliricidia sepium), Season
