Linear alkylbenzene sulfonate (LAS) represents one of active substanceof surfactants in detergents of which in high concentrations may causeenvironmental pollutions. The aim of the research was to know theefficiency of exclusion of LAS and the rate of LAS degradation indetergent wastes by the anaerobic process at fixed bed reactor equippedwith cross flow material. This research was done in Process Laboratory ofBalai Teknologi Lingkungan BPPT PUSPIPTEK Serpong. Reactoroperation was done through continuous process with close circulation, upflow and 5 hours Rate Time Hour (RTH). Exclusion of LAS of detergentwaste was recorded for 17 days. The degree of acidity after the processwithout inoculum (P1.0) was to 8.45, and for an anaerob condition withadded inoculum (P1.1) was 7.88. The efficiency of the highest exclusionof CO soluble was equal to 80.96% (P1.1) with effluent 476 mg/L, and 76.81 % (P1.0) with effluent 531 mg/L. The exclusion of LAS of detergentwastes was 99.19% (P1.1) with LAS effluent equal to 17.51 mg/L and98.3% (P1.0) with LAS effluent equal to 27.84 mg/L. The maximum rate ofLAS surfactant degradationunt 0.95 ppm/day (P1.1) and 0.44 ppm/day(P1.0).

In this experiment, Lemna sp. was exposed to surfactants LAS and ABSand a commercial detergent following method described by OECD. In thetest, 10 fronds of Lemna sp. were grown in a modified MS mediumcontaining the surfactants and detergent in the concentration of 0 ppm to79 ppm and incubated for 7 days under continuous fluorescence lamps.The EC50 values of the detergent and surfactants vary depending on thecompounds and the testing parameter. For LAS and ABS, the value ofEC50 from number of fronds is higher than EC50 from the total chlorophyllcontent, i.e. 14.83 and 14.36 mg/l for LAS and 11.75 and 7.56 mg/l forABS, respectively. However, the total chlorophyll content is not sensitivefor commercial detergent “A” and results in a higher EC50 value of 31.53mg/l. LOEC values for LAS and ABS is 5 mg/l respectively, and is 25 mg/for detergent ”A”.

Economically, Rawa Danau is important fresh water source for cities ofCilegon and Serang and industrial estates in the area. Ecologically, RawaDanau is the last and the only mountainous freshwater swamp still exists inJava island. In the last decade there are several studies that recommendincreasing the capacity of Rawa Danau as water storage. Recently, theMaster Plan of Rawa Danau has been published by the Province of BantenPlanning Agency. It is concluded that increasing the water level in RawaDanau by 2 meters would satisfies the 2010 projected water demand inSerang and Cilegon. We belief that the action could endanger theexistence of both the swamp forest and the rice field in the vicinity. In thispaper we describe an alternative action that could increase the waterstorage capacity of Rawa Danau whilst the ecological function of theswamp could be preserved as well.

Shrimp culture has became one of the most important Indonesian exportcommodity since 1985 up to the beginning of 1990`s. Due to theincreasing intensification, the pressure on the shrimp ponds environmenthas became a serious problem. The problem was indicated by thedecrease in shrimp production since 1992. Dimethylsulfide (DMS) isknown as a major contributor to total sulfur emission from land and coastalmarine and also known to inhibit nitrification. In this respect, we arestudying the influence of DMS on nitrification process in saline water.This paper describes the DMS concentration observed in several places inthe Western Coast of North Java. The minimum and maximum concentrations observed were 790.32 ηM and 6483.87 ηM respectively. These figures are higher than concentration detected in any other coastal area where shrimp productions are concerned. We speculate that DMS has given some contributions in the depletion of shrimp production.

Cirata is one of three reservoirs lay in Citarum River, where the waterbody is used to fish culture in floating net. Lately, one or two times in ayear, fish in the floating n die massly because of the water quality ofet reservoirs have worsen, which resulted from the entering of organicpollutant from human being activities in and outside of the Reservoir. Thispaper is written to reveal contribution of organic waste from fish culture infloating net represented human being activities inside of the Reservoir onthe worsening of water quality Cirata. The result revealed that theReservoir Cirata continually has been polluted by organic waste, whichgradually resulted in the worsening of water quality indicated byincreasing chemical oxygen demand (COD) and concentration ofchlorophyll-a (Chl-a), and decreasing secchi disk. This study indicatedthat on 1997, fish culture using floating net (internal loading) in ReservoirCirata contribute the nutrient three times than domestic and agriculture(external loading). This situation is guessed still going on hitherto,therefore the reservoir become very hypertrophic, as giant cesspools, andresulted in death of fish massly.
