Land degradation represents a form of land productivity decrease that occurs due to the presence of incompatible land usage with land characteristic, which resulted in land capacity deterioration. Land degradation evaluation is determined based on Government Regulation No.150/2000 regarding land degradation control for biomass production, and Living Environment Minister Regulation No. 7/2006 for criteria standardization on soil measurement of biomass production. This research was conducted to evaluate land degradation levels based on physical characteristics of several land use patterns in Gumelar Region. The research used a survey method with homogenous land unit (HLU). HLU approaches were obtained from overlay between land use map and slope map. The measured parameters were i.e. solum thickness, surface rockiness, soil texture, bulk density, porosity and permeability. Results of the samples analysis were compared with the parameters values on Goverment Regulation No. 150/2000. The results of the research showed 69,7% of the total area of Gumelar had undergone land degradation. Garden land use contributed 51.5% land degradation, which was divided into several classes i.e. good and slight damage potential was 12.0%, slightly damaged was 17.7%, slightly damaged with damage potential was 4.8%, and damaged was 17.1%. Dry land contributed to damaged land degradation of 11.3%, and categorized entirely as slightly damaged, while the shrub land use contributes 6.9% of degraded land (with 2.8% and 4.1% were good with slight damage potential and slightly damaged with damage potential, respectively). Largest contribution of land damage towards land degradation was dry land, all dry land in study area were in slightly damaged condition. Garden was the land use with lowest land degradation, which indicates the most suitable land use in the studied area was garden. Keywords: land use, land degradation, homogenous land unit, overlay

The proper understanding about spatial soil diversity is very important to simulate environmental model and to manage land resources in the landscape scale. Information of soil diversity is also noteworthy for environmental academics, forestry, civil engineering, and land use planner. Until now, most of the soil information are derived from conventional soil maps which are lack of detailed information. This condition can increase the uncertainty of model output and can also be an obstacle to the future development of spatial distribution model. According to this situation, the research was conducted in Sub Watershed of Cikeruh, Citarik, and Citarum Hulu. These areas are located in the 6o53’00”S - 6o53’15” S and 107o45’21”E - 107o45’55”E at 780-1800 m asl, The rainfall is classified as type C according to the Schmidt and Fergusson classification with mean rainfall around 1795.66 mm per year. The soils in the research areas are classified as Inceptisols. The research aims to analyze and elucidate the relation between topographic characteristics and soil physical properties. Some parameters studied in this research are elevation, aspect, plan curvature, profile curvature, topographic wetness index (TWI), topographic position index (TPI), and some soil physical properties, such as soil texture (clay, silt, and sand), soil organic carbon, soil bulk density, soil available water capacity, soil porosity and permeability. The results showed that all topographic parameters were related to one or some soil physical properties, except aspect and slope. Topographic variables that are frequently related to soil properties are TPI and TWI. Keywords: topographic characteristics, elevation, aspect, curvature, TWI, TPI, soil physical properties

Acid mine drainage (AMD) is the main problem in open pit mining due to extremely low pH and high solubility of metals. Metal solubility can be reduced biochemically in an anaerobic condition. This research was aimed to design and test artificial wetland system constructed. The artificial wetland has been constructed, it contains with two organic wall, two growing pond, and one collecting pond, each component bounded by dike. Organic wall was placed next to growing pond that planted by Typha sp and Cyperus sp. Collecting pond was planted by Eichornia crassipes. Iron and Manganese were accumulated in the root of each plant. Cyperus sp has a fibril type while Typha sp has rhizome type. The fine roots such as root of Cyperus sp could accumulation Fe higher than a rhizome roots such as root of Typha sp. Productivity of biomass was 31,38 ton/ha for Eichornia crassipes, 17,11 ton/ha for Typha sp, and 16,67 ton/ha for Cyperus sp. Eichornia crassipes has a higher biomass than other plants, but the size of this plant become smaller, it because the lack of nutrient in collecting ponds. Cyperus sp seems more prospective, this plant has better of growth rate than other plants.

Chromolaena odorata (L.) is a potential compost since it has high biomass and contains calcium, manganese, potassium and nitrogen. The aim of this research was to know the potency of siam weed Chromolaena odorata compost on soil chemical and chili plant performance. The experiment was arranged in factorial randomized block design consisted of two factors and three replications. The first factor was variety of fertilizer (no fertilizer, cow manure, siam weed compost and inorganic fertilizers) and the second one was the tanglefoot (with and without tanglefoot). Overall, the results of study showed that C. odorata compost could increased crop performance when compared with the other fertilizers in terms of number of fruits, fresh/dry weight of fruits, dry weight of crops, and N-total (leaf, stem, root and fruit), though there was no difference in fresh weight of crops among treatments. Furthermore, the effect of siam weed compost was not significantly different on soil chemical if compared with all treatments. This study is likely suggesting that C. odorata compost gives a positive effect to crops performance and soil chemicals.Keywords: Chili, Chromolaena odorata, compost fertilizer, tanglefoot
