Erosion in the watershed generally occurs due to land use that ignores the rules of soil and water conservation. There is much activity carried out by people living on land in the Yeh Leh watershed area, which makes the level of dependence is very enormous.The erosion forecast is using the USLE (Universal Soil Loss Equation) to estimate the erosion swift occurs and to obtain illustration in determining the precise soil and water measures in a region. The determination of land capability classification is using Arsyad’s method (1989) in which to classify the land ability by classifying the land ability class based on the value of land limiting factors, which then adjusted to the criteria of classification of land capability. The land use directional determination is applying the scoring method where combining field slope factor, soil sensitivity to erosion and daily rainfall intensity. The erosion level of the YehLeh watershed area is categorized as mild to very severe. A very light erosion level as large as 515 ha (21.01%), with the land use in the form of irrigated rice field and forest. The severe erosion level as large as 990.02 ha (40.40%) with land use in the form of plantations. The very heavy erosion level as large as 945.82 ha (38.59%) with land use in the form of plantations. The classification of land capability in the YehLeh watershed area consists of 5 classes of land abilities: class II of 115, 22 ha (4.70%), class III of 533.95 ha (21.79%), class IV of 423.61 (17.28%), Class VI of 1,102.03 ha (44.97%), and Class VII of 276.03 ha (11.26%), with some limiting factors for instance, soil texture, erosion and drainage. Proposed land use in the YehLeh watershed area use for forest areas is as protected forest of 456.49 ha (18.63%). Proposed land use outside of the forest area consist of 58.51 ha (2.39%) of seasonal crops, annual cultivation area of 990.02 ha (40.40%) and buffer area of 945.82 (38.59%).

This study aims to determine the influence of biofilter made from plastic waste to decrease BOD, COD and Ammonia content and to determine the efficacy of its use to decrease BOD, COD and Ammonia content from the hospital’s wastewater. This study utilized aerobic biofilter processing through a batch system. Variables used in this research are wastewater processing through biofilter media made from plastic waste and processing without biofilter media, with 36 hours retention time. The parameters are BOD, COD and Ammonia content. From the statistical analysis, the use of biofilter media made from plastic waste gives a significant effect to decrease BOD and Ammonia content but made no significant effect to decrease COD. Plastic waste biofilter processing system is very effective to decrease BOD (84,85%), less effective to decrease COD (31,73%) but effective enough to decrease ammonia (50,60%), meanwhile, the standard quality of plastic waste biofilter processing system is effective to reduce BOD and COD content but not effective to reduce the ammonia content after 36 hours of processing time. Further research is needed to study the efficacy of biofilter media made from other type of plastic waste. Moreover, a combination of anaerob-aerobic biofilter processing is required to improve processing efficacy. Keywords: biofilter; plastic waste; hospital wastewater; BOD; COD; ammonia

The use of Agrochemicals for increasing the agricultural products are commonly applied on agricultural soils, especially the soil used for cultivatif cabbage in the area of Kintamani-Bangli, Province of Bali. Agricultural soils used for cultivatif cabbage in Kintamani area commonly apply inorganic fertilizers and synthetic pesticides for increasing the products. However the use of these agrochemicals tends to uncontrol and causes the soils polluted. One factor of contamination of soil is the presence of heavy metals in the soil. Intensive use of inorganic fertilizers and synthetic pesticides can lead to high levels of bioavailability of heavy metals in plants. This study intend to determine the total contents of heavy metals Pb and Cd in the agricultural soils and analyse bioavilability of those metals. The total metals was determined by the use of digestion method involving reverse aquaregia (HNO3:HCl, 3:1) and the bioavailability of the metals was determined by applying single extraction including HCl and EDTA extractions. The results show that the total contents of Pb and Cd in the soils were 4,1261 ± 0,1113 – 14,5923 ± 0,3790 mg/kg and 0,8803 ± 0,0259 - 0,9425 ± 0,0195 mg/kg respectively. The bioavailable metals of Pb and Cd in the soils was 31,14% - 42,53% and 78,70% - 80,73%, respectively.
