Abstract

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.

Abstract

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”.

Abstract

Various organisms, including Lemna sp., have been employed in thetoxicity test of waste, soil, and water. In this experiment Lemna sp. wereexposed to waste water collected from tanneries in Garut, West Java.The experiment system includes liquid medium (macro and micro salts ofMurashige and Skoog), to which a series of concentrations of the pre-filter-sterilized tannery waste water were added aseptically. Aseptic grownLemna sp. were placed on the medium in a density of 10 fronds permedium container. The system was then incubated for 7 days undercontinuous daylight fluorescent lamps and the number of fronds, freshweight and chlorophyll content of the plants were determined. The resultsshow that EC50 of the tannery waste water is 0.66% of waste water. TheLOEC value is 0.1% and the NOEC value could not be determined butshould below 0.1%. This experiment suggests that tannery waste water isdangerous to aquatic plants if it was discharged to public water bodywithout appropriate pre-treatment.

Abstract

Sistem fitoremediasi berbasis rumput untuk pengelolaan pencemaran lingkungan di tambang minyak telah diteliti. Lima jenis rumput, yaitu Scirpus grossus, Brachiaria humidicola, Eleusine indica, Paspalum notatum, dan Setaria splendida ditanam pada tanah tercemar minyak lama berkadar 3,1%. Pengaruh cekaman salinitas dievaluasi dengan menambahkan air formasi (850 mg/L TDS) ke dalam tanah. Setelah dua belasminggu, parameter pertumbuhan ditetapkan dan kandungan minyak dalam tanah dianalisis. Hasilnya menunjukkan, bahwa semua jenis rumput dapat tumbuh pada tanah tercemar minyak lama. Di bawah cekaman air formasi, jumlah anakan dan berat kering tunas B. humidicola dan S. splendida jelas tertekan, tetapi panjang akar meningkat. Sebaliknya, berat kering tunas pada S. grossus meningkat di bawah cekaman salinitas. Berat kering akar semua jenis rumput secara nyata berkurang dengan cekaman salinitas. Nisbah berat kering tunas terhadap akar relatif tidak dipengaruhi oleh salinitas. Kegiatan degradasi minyak dipengaruhi oleh cekaman salinitas. Kandungan minyak yang hilang dari tanah berkisar antara 32% hingga 50% pada semua jenis rumput.Kata kunci: pencemaran minyak, fitoremediasi, rumput, air formasi Abstract Experiment to develop a grass based phytoremediation system for environmental management in oil industry has been established in the green house. Five species of grasses, i.e. Scirpus grossus, Brachiaria humidicola, Eleusine indica, Paspalum notatum, dan Setaria splendida, were planted in 6.5 kg oil polluted Semanggi soil (oil content of 3,1%). The effects of salinity were evaluated by adding 800 ml of produced water (850mg/L TDS) to the soil. Growth parameters of the plants and the remaining oil content in the soil were determined in the end of week 12th after planting. The results indicated that all of the grass species are capable of growing well in the polluted soil. However, under the salinity stress, the number of buds on the stolons or rhizomes and the shoot dry weight of B. humidicola and S. splendida are reduced significantly. On the contrary,the root length of the two species is increased; and the shoot dry weight of S. grossus is increased. The root dry weight of all tested species are reduced significantly; however the ratio of shoot dry weight to root dry weight is not influenced by salinity stress. Overall, the oil removal rate from the soil is in the range of 32% to 50%; S. grossus and S. splendida are being the best. The oil degradation activity of the two species is slightly increased under salinity stress condition.Key words: oil polluted soil, phytoremediation, grass, produced water
