Abstract

Rain water is one source of raw water that can be utilized to fulfill the basic needs of communities clean water. Essentially, rain water has good quality, but it is not the case if it is housed in a rain water storage. However, by using a combination of processing technology Gravity and Horizontal Roughing Filter (GRF-HRF) is expected to increase the value of the feasibility of rainwater that can be utilized. The research was conducted to determine the feasibility of water in rainwater storage qualify as a source of clean water or drinking water, determine the level of turbidity and total suspended solids (TSS) that contained in the rainwater on the rainwater storage, determine the ability of roughing filter combination of gravity and horizontal flow capable of processing water in rainwater storage to be able to meet water quality standards. The research method used in this study by conducting a literature review and analyzing data by using Microsoft Office Excel and SPSS 12.0. From the analysis of the data it is known that the quality of rainwater samples in the rainwater storage on Seruni Village, Musuk, Boyolali, do not qualify as a source of clean water or drinking water. It is based on a large sample test results in five different locations showed the highest level of turbidity of 76.84 NTU NTU and the lowest 23.25. While the content of total suspended solids showed the highest value of 380 mg / l and the lowest 180mg / l. Large decrease in the efficiency of turbidity in the flow variation 5ml / s is 90.67%, the variation of flow of 10 ml / s was 98.30%, and the variation of flow 15 ml / s was 87.88%. Removal efficiency of total suspended solids (TSS) on the variation of flow 5ml / s is 90.91%, the variation of flow of 10 ml / s was 98.45%, and the variation of flow 15 ml / s was 88.23%. There is the influence of variations in flow of the roughing filter efficiency performance in reducing levels of turbidity and total suspended solids.

Abstract

AbstractHeavy metal contamination of waste containing lead (Pb) and chromium (Cr) is a serious problem on the current environmental conditions. Many industries that lead to increased pollution of water sources from waste discharged into waters without first processing. One of the processing environment is contaminated with lead and chromium phytoremediation technology. Plants absorb Pb and Cr potentially one of the plant water spinach (Ipomoea aquatica). The study was conducted to determine how much decrease in the concentration of lead (Pb) and chromium (Cr) and for analysis of wet plant water spinach (Ipomoea aquatica) and the long residence time of optimum to reduce waste containing concentrations of lead (Pb) and chromium (Cr) . Results of the study was a large decrease in Pb concentration of 0.5 mg/l and 0.8 mg/l by the swamp water, reaching 0.001 mg/l and 0.034 mg/l. While the decline in the concentration of Cr 1.5 mg/l and 2 mg/l was 0.25 mg/l and 0.623 mg/l. Analysis of wet kale optimum water is 100 grams. The method of absorption of Pb and Cr concentrations by water spinach is rhizofiltrasi and fitoekstraksi.

Abstract

Sanggrahan landfill is a final processing contained in Temanggung County and is located in the village district Sanggrahan Kranggan with ± 2.6 ha of land. Existing condition Sanggrahan landfill has 2 zones of active landfill conditions now beginning to fill because the garbage has already reached 80%. The condition is caused by the use of the concept of waste management at the Sanggrahan landfill still use the concept of Controlled Landfill. The limited land, and reduction and infrastructure support in the landfill resulted in less optimal waste management, so that it will cause a negative impact on the environment around the landfill. This is the main problem with increasing waste generation from population growth and has not found new land instead. To reduce the negative impact and optimizing available landfill and extend the use of the landfill, it is necessary to waste management with the concept of Sanitary Landfill, and the addition of landfill infrastructure.

Abstract

This research is taken by sample of Banjir kanal Timur. It is conducted by research in order to know the effect of fluctuations in salinity on nitrification, in this research, separating ammonium is conducted by  giving variations of salinity content which is different on each bacteria and reactor. It would be returned to the source of orifice, that is 0,5% of the result. In high salinity, bacteria cannot degrade  ammonium fast, but it can be fast if when it is returned to the source salinity, so by that experiment, we can say characteristic of salinity toxic is temporary in process separating ammonium. In even 0%-3% salinity, bacteria can degrade ammonium well so bacteri which is taken of banjir kanal Timur can be applied to recycle waste which has 0%-3% salinity fluctuation.
