ABSTRACT Organic farming, especially organic rice requires a continuing supply of organic fertilizer in large quantity as a source of nutrition for rice plants. In long-run, organic system is can retain higher soil organic carbon (SOC), partially compensates the negative impact by improving physical and biological properties, as well as nutrient retention capacity of the soil. Azolla pinnata is an organic nitrogen source rich in protein. The high nitrogen content in A. pinnata is related to the presence of nitrogen-fixing Anabaena azollae microsimbion in A. pinnata leaves. A. pinnata compost is an alternative for biofertilizer carrier that can be used in organic rice fields. The contribution of azolla-based organic farming for organic farmers is to decrease the dependency on the animal manure in cropping season. The field experiment comprised of conventional compost as control and combination of organic fertilizer and biofertilizer with Azolla carrier. Organic fertilizer were 5 ton/hectare (ton/ha), 7.5 ton/ha, and 10 ton/ha combined with 0, 10, 20 kg/ha biofertilizer with Azolla carrier with no addition of inorganic fertilizer. Complete randomized design were used in the experiment which consisted of three replications. This technology produced organic fertilizer better than conventional compost of rice straw and manure made by farmers. Organic fertilizer base with Azolla mixture of 7.5 ton ha-1 plus solid biofertilizer (10 kg/ha) can produce 6.58 ton/ha of dry harvested grain, higher than conventional compost treatment (control). The application of organic fertilizer base on azolla and solid biofertilizers gave the increasing yield prospect of organic rice in Cisayong, Tasikmalaya regency West Java.Keywords : Azolla pinata, carbon, nitrogen, organic farming, rice.

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.

The efforts to utilize the agricultural land need a proper understanding of the soil characteristics. The soil characteristics themselves are influenced by the factors that regulate and control the soil forming and pedogenesis processes. The main soil forming factors in this study was the different ages and composition of parent materials from the eruption of Mt. Tangkuban Parahu in West Java. This research was done to comprehend the pedogenesis and to figure out the soil classifications that developed in two geological formations (Qyd and Qvu) and two ages of eruption (Holocene and Pleistocene) of Mt. Tangkuban Parahu. The study was conducted in Ciater, Subang Regency and Jatinangor, Sumedang Regency in West Java Province. The study consisted of four stages: preparation, field survey and soil sampling, laboratory analysis and presenting the report. The results showed that Pedon of Jatinangor consisted of three different stratifications of ages. The clay mineralogical composition was dominated by kaolinite, whereas mineralogical composition of the sandy fractions (heavy fractions) was augite-hypersthene. Pedon of Ciater also consists of three different stratifications of age. The clay mineralogical composition was dominated by allophane, while mineralogical compositions of the sandy fractions (heavy fractions) were green amphibole-hypersthene in the overlying horizons and amphibole-augite in the underlying horizons. The stage of soil formation on both pedon were cambic or viril. The soil classification according to Soil Taxonomy were Acrudoxic Durudands, medial over loamy-skeletal, isohyperthermic in Ciater Pedon and Fluventic Eutrudepts, fine, kaolinitic, isohyperthermic in Jatinangor Pedon.Key words: slow sand filter, activated carbon, silica sand, sand, gravel, zeolite
