An investigation of the influence of smoke reduction in diesel engines was carried out. A smoke filter “ASAP” has been installed between carburetors and injection pump of the tested vehicles, namely: Isuzu Panther, Minibus Toyota, and Truck Mitsubishi Fe 119. The testing procedures follow the standard of STALDAD 2.03-90 issued by the Directorate General of Land and Transportation No. AJ- 402/8/5/1990. The engines were accelerated from low to maximum speed by changing the gear from neutral to highest gear transmission. The result of the testing shows that there was reduction in percentage of smoke in the vehicles, i.e. decrease of 35.73 % for neutral transmission, and decrease of 28.86 % for gear transmission. The testing indicates that the reduction of smoke for the diesel engines on neutral transmission is more significant than in gear transmission

At this moment, Saguling reservoir in Citarum river is not only polluted by waste water from municipal, industry, agriculture and become eutrophicated. This research was carried out in attempt to know how bad is the eutrophication and effecting phytoplankton in Saguling river. This research reveal based on the measured physical, chemistry and biological parameters, Saguling reservoir could be classified into eutrophic with low transparency (<70 cm), high concentration of nitrogen (>1,100 mgN•l-1), phosphor (>0,216 mgP•l-I) and dominated by Mycrocytis and Ascilatoria. This result also approved the previous analysis that overflow of sampling plankton- net always resulting “underestimation” value. Therefore using row metter without filtering and settling methode in phytoplankton is suggested.

The experiments were conducted in the Environmental Engineering laboratory, Griffith University, Brisbane, Australia on samples provided by Redland Shire Council Waterworks. The result showed that ozonation has positive effect towards alum dosages as a coagulant. Ozone dosages were 2.86 ppm, 6.25 ppm, and 11.22 ppm, while alum dosages were 5 ppm, 10 ppm, and 15 ppm. Ca(OH)2 was utilized as pH regulator with the dosages in the range of 4 ppm – 12 ppm. Effects of ozonation on coagulant dosages were measured by color level expressed in Pt-Co units. Maximum color removal was 87% and 89% determined spectrophotometrically with the wavelength of 360 nm and 400 nm respectively.

The gas produced in solid waste disposal sites, particularly CH4 can be a local environmental hazard if precaution are not taken to prevent uncontrolled emissions or migration into surrounding land. Gas can migrate from solid waste disposal sites either laterally or by venting to atmosphere, causing vegetation damage and unpleasant odors at low concentration, while at concentration of 5-15 per cent in air, the gas may be form explosive mixture.Recently, a forest fire on the Indonesian islands of Sumatra and Kalimantan left not only Indonesia but neighboring countries as well covered under a thick cloud of haze. Some palm plantations and palm oil refineries once disposed of palm oil waste (Empty Fruit Bunches ) by drying them in ovens and then burning them in fields. This paper discusses some results of the experimental and theoretical investigations which conducted to examine effects of the utilization of palm oil wastes particularly Empty Fruit Bunches as the fuel of boiler on greenhouse gas emission.

Water pollution in the big cities in Indonesia has shown serious problems. One of the potential sources of water pollution is domestic wastewater that is wastewater from kitchens, laundry, bathing and toilets. These problems have become more serious since the spreads of sewerage systems are still low, so that domestic, institutional and commercial wastewater cause severe water pollution in many rivers or water body. This paper describes alternative technology for treatment of wastewater or organic wastewater using submerged biofilter. Using anaerobic and aerobic submerged biofilter within total one day residence time can decrease BOD, COD and Suspended Solids (SS) concentration more than 90 %.

Clean water needs and wastewater treatment will be a serious problem for industry especially for food industries. The packet information of applicable technology for water treatment and industrial waste handling that can support any development sector nowadays is needed by any kind of society especially for small and medium enterprise players. To face on globalisation, the computer and information technology will be used as an important tools for distributing the packet of technology from R&D community to any kind of society through global network. By using the existing network infrastructure in the country, the packet information of technology will be distributed electronically specially to help group of small and medium industry. As pilot project, this activity chooses the tahu/tempe industry located in Semanan, Jakarta Barat for the industrial centre. By surveying the need of technology, we try to help craftsman to resolve their problem on clean water supply and industrial waste, so they can increase their product quality.

Teknologi silase adalah teknologi fermentasi yang biasa digunakan untukmengawetkan hijauan makanan ternak. Sebagai usaha memperkenalkan teknologi silase ini pada para petani, maka telah dilakukan kegiatan pelatihan proses produksi silase dengan tujuan utama memasyara-katkan teknologi pengawetan hijauan makanan ternak berupa pengawetan basah dengan teknologi silase. Hasil yang dirasakan ternyata menunjukkan betapa sulitnya teknologi yang sudah “proven” diterapkan tanpa kejelasan akan pasar dari produk hasil terapan teknologi tersebut.Selain itu para peneliti juga perlu bekerjasama dengan pemasar produk teknologi, agar biaya R & D dapat dikembalikan lagi ke masyarakat dan penerapan teknologi tidak berhenti sebatas berhentinya program.

The aim of this experiment is study on technique of gamma irradiaton in analyzing dying agent direct orange 34 in waste water. Direct orange 34 was dispersed to oxalic and malic acids when the 60Co irradiated. The result showed that dose and dose rate of 60Co were less than 10 kGy and 7.57 kGy/hour, respectively. While, the pH of the first solution was 7.0. The technique showed that the chemical oxygen demand of dye solution was decreased from 60.38 to 4.90 ppm.

In Indonesia, the serious problems of degradation water quality from nonpoint source pollution was not yet many applied on watershed. Agricultural activities such as cultivation and application of fertilizer and pesticide will influence water quality, with activities in runoff-producing zones and near streams having a greater effect than those elsewhere. Water quality integrates all sources of pollutants. Nonpoint sources, by definition, are diffuse and not easily identified or quantified. The control technologies and best management practice available are generally expensive to beimplemented. AGNPS model is a model hydrology that should used to identify and quantify the nonpoint source pollution from watershed. The AGNPS is an event-based model that simulates surface runoff, sediment, and nutrient transport primarily from agricultural watersheds. In addition, the model considers point sources of water, sediment, nutrients, and chemical oxigen demand (COD) from animal feedlots, and spring. The model has the ability to output water quality characteristics at intermediate points throughout the watershed network. Seven parameters were selected out of twenty two parameters based on their significance in sensitivity to hydrology, erosion and sediment, and nutrient yield output. That seven parameters consist of SCS curve number, Manning’s roughness coefficient, cover and management factor, land slope, channel sideslope, practice factor and fertilization availability factor. Omitted parameters in the hypothetical scenario formulation were either parameters of uncontrollable nature such as rainfall, EI30, soil erodibility, or parameters that had least significant sensitivity such as field slope length and channel slope. The simulation with BMP system has been conducted from the parameter adjustment for seven parameters. The BMP scenario was mosteffective in reducing the degree of volume and peak runoff rate by 32,08% and 29,66% from the base value of 0,53 inches and 118,51 cfs. All erosion and sediment related nonpoint source pollutants were significantly reduced by 66,36% from the base value of 135,67 tons by altering the cover and management factor (C-factor) and the practice factor (P-factor). At the time that, total N dan total P were significantly reduced by 56,85% and 57,92% from the base value of 11,15 lbs/acre and 7,01 lbs/acre with that same of methods.
