Water is the main needed for human being. The increasing effort of general health and healthy life-environment is influenced by quality and quantity of water. Therefore, we need to process water with some methods. In fact, the ADKL (Analisis dampak kesehatan lingkungan / environmental health impact analysis) study held in 2001, indicate that water quality from dig-well in Moyudan, Sleman, Yogyakarta, was below the standard of pure-water quality. It is important to complete the pure-water needed from dig-well with simple model processing from local resources by apropriate technologies in order to increase the water quality in household. Structureof the process, consist of : aeration that principally give chemical oxidation, filtration for filtering dirty material and disinfection for killing the microbes.The aim for this research was to understand the increasing of water quality from dig-well in Sumbersari, moyudan, sleman, yogyakarta on parameter of E. coli, nitrite, nitrate and sulphate, after processed by aeration, filteration and disinfection model with variation of debit : 1, 2 and 3 liter/minute. The research was experimental type with pre-test and post-test group design. Location of the research was in Sumbersari village, moyudan, sleman, yogyakarta. The independent variable was dig-well processing using aeration, filtration and disinfection model with variation of debit, while, the dependent variable were the decreasing/increasing of E coli, Nitrite, nitrate and sulphate. The result showed that after processed, E coli and nitrite was decreased, while Nitrate and sulphate was increased. Value of the parameter was below the standard. We suggest that, people of sumbersari vilage, Moyudan, Sleman, Yogyakarta, use the simple dig-well processing to improve the water quality of their dig-well.

Waste as one of human activity products should be managed in order to minimize its negative impacts to the environment and human health. Environmental pollution will also take place due to waste which contains hazardous substances, such as used battery, accu and broken TL bulbs. Production of those goods uses plublum (Pb) in its process, so that the Pb will be carried later by the leachate flow to the environment. This work was an experiment with pre and post tests design which also used reference group as a control towards Pb parameter. Statistical analyzes was carried out using Anova and T tests with the degree of confidence of 95%. Result of the anova test of reference group with a variation of detention time was probability of about 0.293, whereas the experimental group resulted a probability of 0.005. The T-test for both reference and experimental groups with a variation of detention timegave different values of Pb parameter where the different with the probability of 0.000. The result showed that concentration of Pb in leachate decreased after it was treated using alum and lime. the significant reduction is at leaving time of 3 hours, i.e. 798.3 mg/L (75.7%). Therefore, it ca be concluded that treatment using alum and lime can be applied to reduce concentration of Pb in a lechate.

PENGOLAHAN LINDI (LEACHATE) DENGAN MODEL COAGULATION - BIOFILTER UNAEROBIC Sri Puji Ganefati

Leachate, especially from the landfill, is a pollutant that can harm human health and pollute the environment including aquatic biota, because the leachate contains various chemicals both organic and inorganic substances and also pathogen bacteria. Laboratory test by Department of Health – Yogyakarta (2001) showed that leachate from landfill had Biological Oxygen Demand (BOD) of 1032 mg/liter in which this was much higher than the limit allowed (BOD = 150 mg/liter. In order to reduce BOD in leachate, a treatment is needed. In this experiment a treatment to reduce BOD in leachate was carried out by applying coagulation andanaerobic bio-filtration with the time of 1, 2, and 3 hours. Evaluation of the tests was conducted using pre-test and post-test with control design which analysis was made descriptive and analytically using T-test with the error of about 5% (á =0,05). Results of the experiment indicated that there was a tendency of BOD reduction of about 0.9% - 1.1% for the control samples, whereas the BOD reduction for leachate attained 82.3% -90.5%. Based on the T-Test, the probability result was 0.000 (p< á =0.05). This means that there is a significant difference in BOD reduction between control samples and leachate. In other words leachate treatment using coagulation – anaerobic bio-filtration can be taken as an alternative process to reduce BOD.
