185Pergeseran Kebijakan Dan Paradigma Baru Dalam Pengelolaan Daerah Aliran Sungai Di IndonesiaIntegrated watershed management, which aims at restoration of a sound hydrologic regime in the watershed considering water resources utilization, appropriate landuse, water quality control and environmental conservation, is becoming crucially important in Indonesia. Because, the land degradation of watershed in Indonesia more increases every time. There is a growing concern that many parts of the Indonesia watershed will continue to face problems of watershed degradation. The basic problem in most watershed area, especially in Java, is too many people being concentrated on too small land base. Besides that, the causes of watershed degradation are complex and interrelated, such as too much emphasis being placed on economic growth in the management of natural resources, and the continuing presence of poverty, population growth, infrastructural and industrial development. Thus, the exisiting environmental problems and their overall impacts are not only biophysical in nature, but also social. The integrated watershed approach stresses the interaction of all activities that take place throughout the watershed. The strategy of watershed management approach uses new paradigm with people of participation and using community development in operational, practices and bottom up approach.pengelolaan DAS, kebijakan, partisipatifSutopo Purwo Nugroho

195Hub. Tingkat Konsumsi Ikan Laut Thdp Kadar Mercury Dlm Rambut&Kesehatan Nelayan di Pantai KenjeranSurabaya Kenjeran Beach, as a part of Eastern coastal area at East Java, in addition to has function as a sea recreation (a tour) place and fishing, it also estuary for community channel and rivers from city. The condition of Surabaya Kenjeran Beach effected by Hg pollution, had observed by previous researcher, they suggested that water, sediment, and fishes from Kenjeran Beach were already dirtied by Hg at dangerous level. Hg that can be found in industrial waste generally has a inorganic form, but in the water environment, inorganic Hg change into organic Hg by microorganism (for example, methyl Hg) which is more toxic. Fisherman communities is one of the group which have a risk getting effect of methyl Hg, because they usually eat fish from sea that dirtied by Hg.
This research plan is case control, in order to studying relations between consumed sea fish and degree of Hg in fisherman?s hair, measuring average degree of Hg in their hair and than compare it with limit value, and also studying healthy disorder sigh that likely appear as a result of Hg poisoning. This research took place at Kenjeran district, Bulak sub district, Surabaya. The number of samples for group who affected by Hg are 70 person and controlled group are 45 person. Respondent?s hair (research subject) was taken and then observed by Atomic Absorption Spectrophotometer (AAS) No Flame.As result, at the fisherman group who consumed sea fish at average 99.11 g/day, they have degree of Hg in their hair is 256.086 ppb. There are no data of consume sea fish at that time for the controlled group, average degree of Hg in their hair is 0.511 ppb. Healthy disorder sigh (subjective symptoms) which is suspicious as a result of Hg poisoning at this research are kidney, lever disorder, headache, painful, tremor, bleeding gums, and visual disorder.Conclusion is, statistically there is significantly relations between consumed sea fish and degree of Hg in hair, and average degree of Hg in the effected group?s hair is higher than the controlled group, but it?s not over limit value that recommended by National Research Council (NRC) is 12 ppm, also there is significantly relations between degree of Hg in hair and healthy disorder sigh (subjective symptoms).

199Pendekatan Ekonomi Dlm Pengembangan Suatu Metodologi Utk Perkebunan Energi Pd Lahan KritisAs a result of population pressure, deforestation in Java has increased considerably that causes an increase on critical land. The situation is worsened by increasing of kerosene and diesel prices that causes to an increase on fuelwood utilization that would lead to increase of illegal cutting. The increase of critical land could lead to increase of soil erosion, landslide, and flood as a result of a reduction in water absorption and soil retention. The Department of Forestry has initiated a reforestation program to ameliorate the situation. However, as the limited budget, the economics of the program needs to be examined further.
Based on benefit-cost ratios, economic contributions of the fuelwood component indicated that the reforestation program or energy plantation was economically unfeasible. However, by including benefits of soil erosion control the program was economically attractive on some sites. A methodology was developed to prioritize which critical land to reforest. This was applied by identifying market price of fuelwood at minimum yield that would justify an energy plantation investment. The method indicated that subject to budget availability, critical lands should be reforested in descending order of productive potential until the site of minimum yields is reached.
