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

Conducted in peatland forest of Central Kalimantan, Kalampangan, the aim of this research is to study about the distribution of peatland thickness and peatland traits based on peatland thickness differences and the depth of sampling test. Determination of plots are carried out by the path system which is parallel with river. Derived from 12 different points of observation, the result show peatland thickness variations. The range of thickness is between 3,72m – 6,2m. Those peatland thickness is categorized as very deep. Distance from river does not determine the number of thicknesss. Maturity level of the peat is categorized as hemic and sapric. The average volume in 100cm depth is0,15 g.cm-3 and 0,23 g.cm-3 in 50cm depth. Peatland thickness affects moisture content and total Fe. Peatland depth affects moisture content, volume and total Cu. The moisture content and total Cu are lower in 50cm depth compare to 100cm depth. On the other hand, the volume is higher in 50cm depth. Interaction between peatland thickness and sampling test depth affects moisture content and total N content. The highest moisture content is in 4m and 6m thickness and in 100cm depth. Keywords : Deep peat, thickness distribution, physics and chemistry traits

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

Abstract

Wood consumption in Indonesia is increasing, meanwhile wood from natural forest is decreasing. Consequently the wood industry is widely supplied from fast growing plantation forests, with 15 years rotation or 10 m3 /ha/year growth yield. One of fast growing species is Jabon (Antocephalus cadamba) which can be harvested at 5 years with the price of Rp 900,000.00 per cubic meter. Jabon has been planted in various areas, one of them in Widodomartani, Ngemplak, Sleman, Yogyakarta Province. Jabon is a new plant in the Widodomartani community and has not been widely known for its growth. This research aims to determine the growth and pest attacks on plants jabon. The growth data (height and diameter) was taken from the sample in each treatment (6 treatments). The number of samples in each treatment was 10 trees repeated 3 times, so the total sample was 30 trees for each treatment. The data obtained were analyzed by ANOVA and if there were significant differences in the factors, followed by the LSD test. The growth rate of jabon at 4 years planted on 2 x 2 meters spacing is moderate, with live percentage of 73.31%, plant height 13.59 m and 10.71 cm diameter. Types of pests that attack jabon include stem borer with low attack intensity (8.6%) but cause severe damage (dead plants 83.33%), and leaf caterpillar with a total attack intensity (100%) but resulted in moderate damage levels (60.52% of live plants). Keywords : Growth, Pest Attack, Antocephalus cadamba

Abstract

Forest transition in rural area derived by community landowner and supported by Indonesian Government Reforestation Programme at beginning. Meanwhile, landslide still occur in some region as well as Kulon Progo District of Yogyakarta Province. Land evaluation is needed in order to review forest land-use parcel due to landslide susceptibility. This research combines some procedures consists of Land Capability Analysis by scoring method regarding to Land Capability Assessment published by USDA (United States Departement of Agriculture) followed by Land Suitability Analysis, and forestland use planning by scoring method regarding to Ministry of Agriculture Declare number 837/Kpts/UM/11/1980 and number 683/Kpts/UM/8/1981 followed by Suitability Analysis. The results showing the wide range of land capability classes, i.e. I, II, III, IV, VI and VII. Result of Land Suitability Analysis showing generally Suitable Land-use, but Not Suitable for settlement in VI and VII classes of Land Capability also for Paddy Field in IV, VI and VII classes. The study area can be classified as protected zone 5,06%, buffer zone 41,16%, and cultivated zone 24,61%, when 65,40%, 29,40% and 3,69% for Suitable used, Positively Not Suitable and Negatively Not Suitable respectively. High pressure land use founded in steep land of mountainous area by respiratory cliff for settlement and road among high density of tree crown. Proposed land use for forestland by these procedures still inadequate due to the map scale used for rural area wiches unseparate land use for woodland and peasant's house. Future research need into account for landslide susceptibility assessment in specific site used for settlement among the forest cover due to the sustainable land-use and safety life.
