To assess the possibility cause of deterioration to rice production in several villages downstream to Rancaekek, Bandung, we conducted laboratorium experiment using Lemna as the bioassay agent. Lemna sp. has been exposed to mixtures of inorganic tissue culture medium salts and filtered raw wastewater (effluent) taken from textile mill in Rancaekek, Bandung. The system was then incubated for 7 days under continuous daylight fluorescent lamps and the number of fronds and fresh weight were determined. The results show that EC50 of the textile industry s wastewater is 37.5% of the wastewater. The LOEC value is 30% and the NOEC is 15%. This experiment suggests that wastewater from textile industry is potentially dangerous to aquatic plants, including rice and vegetable, if it was discharged to public water body without appropriate pre-treatment.

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.

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.

Kurangnya pemanfaatan modul termoelektrik sebagai pembangkit listrik di masyarakat sering diakibatkan energi yang dihasilkan cenderung tidak stabil. Sehingga diperlukan sebuah rangkaian penstabil tegangan yang dapat menaik dan menurunkan tegangan menjadi tegangan tertentu. Tujuan proyek ini adalah merancang sebuah rangkaian penstabil tegangan DC skala pico berbasis boost converter. Pengujian dilakukan dengan 3 tahap, yaitu pengujian rangkaian penstabil menggunakan sumber adaptor yang mempunyai tegangan masukan 3-9 V, pengujian kinerja pembangkit termoelektrik pada beberapa ∆T tertentu dan pengujian rangkaian penstabil menggunakan sumber termoelektrik dengan ∆T yang sama dengan pengujian sebelumnya. Hasil pengujian pertama, saat diberikan tegangan masukan 3 hingga 9 V maka menghasilkan tegangan keluaran 5,07 hingga 5,08 V sehingga memiliki persentase ketepatan 98,55% terhadap tegangan 5 V yang diharapkan. Pada pengujian kedua, yaitu saat ∆T bernilai 30, 50 dan 70 °C menghasilkan tegangan keluaran 2,5, 3,04 dan 3,39 V. Sementara pada pengujian ketiga dengan ∆T yang sama menghasilkan tegangan keluaran 5,08 hingga 5,09 V. Namun, saat ∆T bernilai 12 °C mengeluarkan tegangan 0,8 hingga 0,9 V baik pada pengujian kedua maupun ketiga, hal ini disebabkan tidak memenuhi tegangan kerja sistem penstabil yaitu 2 hingga 24 V. Hubungan antara ∆T terhadap Tegangan Keluaran (V), Arus (I) dan Daya (P) yang dihasilkan memiliki nilai R positif 0,76 hingga 1, yang berarti adanya hubungan berbanding lurus. Sehingga, semakin besar nilai ∆T maka akan berdampak pula pada semakin besarnya nilai V, I dan P yang dapat menjadi indikator kualitas pembangkit termoelektrik yang sedang diuji.

Motorcycles are a means of transportation which plays an important role in people's lives. One of the existing problems on the motorcycle is the indicator system or often called by speedometer, an indicator system showing the value of the volume of fuel oil. In fact, the sensor unit used by the indicator is not a volume sensor but the surface of the fuel sensor in the form of mechanical potentiometers. This equipment irregularly measures oil tank so that the mathematical approach to formulate the relationship between surface height and gasoline volume will be difficult. Therefore, to interpret the data manipulation done by comparison method is the method of comparison experiment and calculation. This method is applied in this research due its more superior accuracy and efficiency. This research designs hardware for monitoring fuel oil based on Radio Frequency Identification (RFID) using AT mega 328 as main controller and LCD to display driver’s identity sent by General Packet Radio Service (GPRS). The sensor used is a buoy sensor, measuring the fuel volume between 0.20 liters to 9.55 liters. It is known that the comparative method has an average rate of 16.1%, in measuring the fuel volume between 0.20 liters to 3.68 liters. It is known that the comparative method has an average rate of 17.9%. On measuring the fuel volume between 0.20 liters to 3.43 liters, the comparative method having an average rate of 7.2% is employed. Based on the test results, the best comparison method in comparison with the interpolation method with the average rate of smallest 7.2% is determined.
