Industrial waste pollution from the upstream of the Bengawan Solo river, makes the river's quality unfit for various purposes. Water filtering needs to be done first to improve its quality. One of them is the absorption process. One of the adsorbents that have good prospects is rice husk waste because of its ability to bind the adsorbate components. Study related to the effectiveness of rice husk charcoal as a water filter material need to be carried out before it can be used as a water filter material. Making appropriate filter technology needs to be done to apply it. The results of the analysis show that the filter can improve the physical parameters of water, namely reducing the residue by 25% on average. Meanwhile, from inorganic chemical parameters, only DO (Dissolved Oxygen) elements have decreased in quality standards. The organic chemical parameters, namely the phenol content are relatively constant, this indicates that rice husk charcoal is not effective in binding phenols. Based on Government Regulation No. 82 of 2001, the filtered water is classified as Class I. However, in its use, other parameters that have not been studied should be studied, namely microbiology, other organic chemistry, radioactivity, etc.The technological capacity needs to be increased by the use of a larger body and or a reduction in the thickness of the filter layer. Meanwhile, the manufacture of rice husk charcoal should use controlled combustion mechanisms and or husk charcoal activation with the chemical Na OH to strengthen the properties of the husk charcoal adsorbent against harmful chemical compounds.

Jatibarang reservoir serves as water supply in dry season and controlling flood in Semarang City. This reservoir is stem Kreo River which cathment areas of 54 km2, pool of area 110 ha and volume is 20 billion m3. This reservoir is potential to develop as natural fisheries area. The goals of this research were to explore existing condition of physical, biological as well as chemical parameter; carrying capacity assessment for natural fisheries; determining appropriate fish species to be developed in Jatibarang reservoir. This research was done in descriptive explorative scheme. Field survey and laboratory analyses were conducted to identify physical, chemical and biological parameters of the water. Physical parameters measured were temperature and water brightness. Chemical parameters measured were pH, DO, phosphate, Ammonia, nitrites and nitrate, while biological parameter measured were chlorophyll-a concentration. Carrying capacity analyses was done referred to the Government Regulation Number 82, 2001 that regulate the management of water quality and water pollution control. Based on the research, it showed that the existing condition of physical, chemical and biological parameters were still good to be used for natural fisheries. Based on TSI index, it classified as eutrofic water. Furthermore, tilapia fish (Oreochromis mossambicus), nile tilapia (Oreochromis niloticus) tawes (Barbonymus gonionotus) and carper fish (Cyprinus carpio) were considered as best species for natural fisheries in Jatibarang Reservoir.

One of the major universal threats is water pollution. The untreated distilleries effluent discharge into the environment creates a serious problem to the living systems. It may contain carcinogenic aromatics amines, dyes, organic and inorganic chemical compounds. The physicochemical characterization of effluent was collected from Trichy Distilleries & Chemicals pvt Ltd, Tiruchirappalli, Tamilnadu, India and the chemical analyzed in Soil Testing Laboratory, Tiruchirappalli. The effluent was analyzed by different parameters. The physical parameters are BOD, COD, and DO, TDS, pH and electrical conductivity. Heavy metal analysis included Zinc, Lead, Manganese, Arsenic, Iron, Mercury, Copper, Chromium, Cadmium and Nickel. The soil sample was taken from Trichy Distilleries and Chemicals Ltd and analyzed by serial dilution technique. The three microbes such as Escherichia coli, Bacillus subtilis and Pseudomonas putida, were isolated from soil source. The isolated organism was treated with the effluent for various concentrations in various hours. The metal accumulations were identified in soil test lab, Trichy. The hyper accumulations of metal in microbes were identified. The present study explores the effectiveness of bioremediation has a simultaneous removal of Zinc, Lead, Manganese, Arsenic, Iron, Mercury, Copper, Chromium, Cadmium and Nickel from the distilleries effluent. Bacillus subtilis bacterial strains effectively remove the heavy metal from the distilleries effluent.

The aim of this study was to measure and assess the physical and chemical parameters of water quality in the area of ​​fixnet cage cultureat Lake Tutud Tombatu TigaVillagewhich included temperature, pH, DO, TDS, NO3, NO2, NH3 and PO4 in a different time.This research was conducted from August to November 2016. The research activities consisted of direct measurements in the field (in situ) using a Horiba instrument and laboratory analysis (ex situ) at the Agency for Industrial Research and Development Research Institute of Standardization and Industrial Manado. Determination points were done by purposive sampling which refers to the physiographic location wherever possible in order to represent or describe these waters.Water quality measured at4 stations using a Horiba at a depth of 0.5 meters from the bottom of the lake.Station I represented Inlet water, Station II where the cultivation A, Station III where the cultivation B and Station IVwhere no cultivation. The data obtained and collected were primary data i.e., measurement of physical and chemical parameters of water quality as well as watching for signs of sick fish, dead fish, and the growth of farmed fish.The results showed the water temperature ranged between 28-29 ° C, TDS 0266-0412 mg/L and chemical parameters for dissolved oxygen 2-5 mg/L, pH 7-8 and for the results of laboratory analysis, N03(0.7 - 6.3 mg/L), NO2(0001-0002 mg/L), NH3 (0180-1920 mg/L), PO4(0020-0209 mg/L). In general, the existence of water quality of lake Tutud were still in good condition except for NH3 concentrationthat exceeded quality standard limitsof Government Regulation No. 82 of 2001. Basically lake Tutud can still be used for fish farming, but the addition of new cages were not recommended.   Keywords: Lake Tutud,water quality, physical parameters, chemical parameters, fix net cage

Communal wastewater treatment plant (CWWTP) has been chosen as one system to treat domestic wastewater due to simple technology, flexible management, and cost-effectiveness. There are 376 CWWTP have been recorded by Environmental Agency of Yogyakarta (DLH DIY) that spread in five regencies. Monitoring results on CWWTP effluent showed that some physical and chemical parameters did not meet the domestic wastewater standard. Therefore, evaluation of removal efficiency in terms physical and chemical parameters are necessary. The samples were collected from nine CWWTP in Banguntapan, Bantul and Gamping sub-districts. The physical and chemicals parameters (pH, TSS, BOD, COD, Ammonia, oil, and grease) of influent and effluent from CWWTP are analyzed based on National Standard of Indonesia (SNI) for domestic wastewater. The results show that BOD (>70%) and TSS (>50%) have better removal effectiveness compare with COD, ammonia, oil, and grease (40%). Overall, CWWTP in Banguntapan subdistrict has better performance compare with CWWTP in Bantul subdistrict.

Wood vinegar rice husk contains a chemical compound that can be used as a biopesticides. Wood vinegar contained compounds which estimated potential as repellent, antifeedant, antimicrobials, antioxidants, disinfectants and as preservatives. The content of chemical compounds in the wood vinegar must be identified. Identification were done by calculating the concentration of acid, phenol and an infrared spectrophotometer. Production of wood vinegar made by the pyrolysis process used pirolisator. Most of the wood vinegar obtained is evaporated using a rotary evaporator and partly extracted using the method of separating funnel. Compound of acid and phenol in wood vinegar evaporation were higher than the extraction of wood vinegar. These results were confirmed by an infrared spectrophotometer spectrum showed the functional groups of acid and phenolic compounds. Keywords: wood vinegar rice husk, acid, phenol, pyrolysis, infrared spetrofotometer
