Abstract

The main problem of domestic wastewater treatment in term of bacterial removal using conventional septictank in many developed towns is lack of land to purify domestic sewage into 10 m minimum safety distance according to WHO regulation. It is necessary to develop new treatment system to ensure bacterial will be removed 100 percent less than 10 m distance. Channel System Filter Septictank (CSF Septictank) is designed to solve the problem above. CSF Septictank is a common septictank equipped with filter tank separated by several partition walls to shape channels. CSF will consist of three parts: initial storage tank, filter tank and final storage tank. The Filter tank is fully filled with fine sand as filter medium. Wastewater will flows from the initial storage tank then pass the filter tank and entering the final storage tank as product of CSF Septictank treatment. Dimensions of the filter tank are analyzed using Huisman formula. Performance of CSF Septictank is measured by comparing water quality between water in the initial storage tank and the final storage tank. Water quality test result shows significance effect in bacterial removal. The other parameters also show increasing of water quality. By using CSF Septictank, bacterial contents could be removed 99,15%, BOD5 contents decreases 27,24%, COD contents decreases 29,01% meanwhile DO contents increases 27,78%

Abstract

Measurement of water quality is always experience method advanced time by time. Advancing in method of water quality measurement directing to easier, faster and more valid technique. Beside parameters such as DO, BOD5, KMnO4that is always used to determine water quality, chlorophyll-a could be the one of parameters that is used to measure the healthy of water body. Chlorophyll-a is commonly used to measure trophic status of water body. Chlorophyll-a can be measured in easy, fast and valid technique. Therefore, chlorophyll-a could be used as practical methode in measurement of water quality. This research is ordered to find formulative correlation between chlorophyll-a with DO, BOD5, KMnO4. Knowing formula related among those parameters, we know the value of DO, BOD5, KMnO4 only by measure the value of chlorophyll-a. Based on this research formulative correlation between chlorophyll-a with DO, BOD5, KMnO4 is couldn�t be founded. But, from this research can be resumed that Gadjah Wong river trophyc status is mesotrophyc-eutrophyc

Abstract

To reach the regional development equity, it is necessary to spread central activities in sub-region. This is a land use planning need to gain. According to development paradigms, industry is a leading sector that will influence its hinterland. This research was aims to know the strategic location for industrial area in Purbalingga, that have consideration in phisichal, economic, social, and stakeholders’ interest. The result indicate that industry should not located in central region as we saw in existing. The best alternative location for industrial area are Bukateja, Kutasari, Rembang, Mrebet, Karangreja , and Karangmoncol.
