STRATEGI PENGELOLAAN SUNGAI CIBANTEN PROVINSI BANTEN BERDASARKAN ANALISIS DAYA TAMPUNG BEBAN PENCEMARAN AIR DAN KAPASITAS ASIMILASI

Cibanten river is one of the most potential to be developed as a source of raw water. Crucial issues at Cibanten river is the increasing load of water pollution as indicated by parameter BOD, COD and TSS. This study aimed to estimate the amount of Total Maximum Daily Load (TMDL) in Cibanten river, analyze the quality Status of the Cibanten river water, analyze the capacity of assimilation, and determine management strategy of Cibanten river of Banten Province. TMDL of BOD were determined by modeling Qual2KW and the results were compared with the second class water quality standards to regulation No. 82/2001. Management strategy of Cibanten river determined by analysis of the results of an expert survey method with AHP (Analytical Hierarchy Process). Quality Status of the Cibanten river water with pollution index was light raiment and storet method of Raw Water Quality class II belong was heavy raiment. Results of the simulation calculation of TMDL, the total load of pollution in the Cibanten BOD was730 tons/month while the TMDL of BOD was 146.801 tons/month. Results of the analysis of assimilation capacity COD was 24208 tons/month. Results of the analysis methods of survey expert with AHP (Analytical Hierarchy Process) is monitoring and surveillance as an alternative management strategies with the highest priority of the Cibanten river (agregate value 0.202)and following up the monitoring results.

Strategi Implementasi Produksi Bersih untuk Meningkatkan Kinerja Industri Gondorukem (Studi Kasus Nagreg Jawa Barat)

This study aimed to audit environmental performance in gondorukem (resina colophonium) industry, analyze the main problem of waste and formulate the direction of industry development by cleaner production method. Data collection was conducted by field observation, interview and expert surveys. The analysis method used in this research is cleaner production audit which consist quick scan on stages of production process and formulation the cleaner production option, continued prioritization with Analytic Hierarchy Process. This study was case study take place in nagreg west java. Results of the analysis showed that scheduling sap delivery to be a priority based alternative with the largest value analysis id 0,216 compared with other alternatives.

STATUS KUALITAS AIR DAN UPAYA KONSERVASI SUMBERDAYA LAHAN DI DAS CITARUM HULU, KABUPATEN BANDUNG

Relationships between water quality and catchment characteristics are examined for rivers in the Upper sub Watersheds of Citarum using a GIS-based approach. The study aimed to analyze the relationship of type of land cover and water quality parameters in response to surface runoff. The multiple linear regression model was evaluated to demonstrate the relationship between the both variables. Stepwise multiple linear regressions demonstrated that agriculture and settlement land cover type was able to describe the overall water quality status. Physico-chemicals of water quality parameters could be sufficiently predicted using one land use/land cover type. Stepwise regression results showed that paddy field were significantly related to pH, DO, BOD and COD.Forestrelated significantly to TDS and temperature in dry periods. Water quality parameters over the period of the rainy seasons including agricultural related significantly to temperature, BOD, COD, TP and H2S. Nitrite and TDS had relationship with settlement and paddy field had relationship with pH and TSS. Moreover, only forest had relationship with DO in wet periods. The overall statistically relationships were significant in p < 0.05. This research provides perspective relationship between water quality and land cover types which is an important factor for the water resources conservation in the management plans.
