Hubungan yang erat antara penggunaan teknologi dan kerusakan lingkungan telah menyadarkan masyarakat untuk melakukan modifikasi dan inovasi dari teknologi yang ada saat ini. Penggunaan bahan bakar fosil, seperti batubara untuk pembangkit listrik akan dapat meningkatkan emisi partikel, SO2, NOx, dan CO2. Adanya peraturan pemerintah tentang standar emisi untuk pembangkit listrik di Indonesia, mendorong upaya untuk selalu mengurangi emisi tersebut. Batubara diperkirakan paling dominan digunakan sebagai bahan bakar untuk pembangkit listrik di masa datang. Penggunaan batubara dalam jumlah yang besar akan meningkatkan emisi gas buang di udara. Salah satu cara untuk mengurangi emisi adalah dengan menggunakan teknologi bersih. Ada dua cara dalam menerapkan teknologi tersebut, yaitu pertama diterapkan pada tahapan setelahpembakaran dan kedua diterapkan sebelum pembakaran batubara. Pada tahap pertama dapat digunakan teknologi denitrifikasi, desulfurisasi dan penggunaan electrostatic precipitator. Pada tahap kedua menggunakan teknologi fluidized bed combustion, gasifikasi batubara, dan magneto hydrodynamic.

Kebutuhan Oksigen Biokimiawi (BOD) adalah salah satu parameter kualitas limbah yang banyak digunakan untuk memprakirakan kekuatan suatu limbah mencemari calon badan air penerimanya, bahkan sering digunakan untuk memprakirakan status pencemaran suatu badan air. Dengan demikian BOD mempunyai peranan yang sangat penting dalam usaha untuk mempertahankan daya guna suatu ba:dan air. Benarkah parameter BOD sehebat itu atau pantaskah uji BOD diperankan sebesar itu. Paper ini berusaha menguraikan dan mengkaji tentang kelebihan dankelemahan uji BOD, dan hasilnya mengisaratkan bahwa sebagai parameterkualitas limbah, BOD tidak banyak memiliki kelebihan dari parameter lainnyakecuali kepraktisan yang bisa menyesatkan. Oleh karena itu maka sebenarnya uji BOD belum dapat digunakan sebagai alat meneliti, namun justru masih harus dijadikan bahan penelitian; atau harus diteliti. Akhirnya untuk menentukan kekuatan limbah dilapangan penggunaan COD (kebutuhan oksigen kimiawi) lebih disarankan.

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 %.

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.
