Activities at Timbul Roso Restaurant generate not only useful product but also causing negative impacts such as liquid waste which is potential to harm people’s health and pollute the environment if it is not adequately processed. The preliminary survey results on the liquid waste revealed that the BOD and TSS concentration were 538 mg/l and 470.50 mg/l respectively, or had not yet fulfilled the quality standard permitted by the Decree of Minister of Environment No. 112/2003 about Domestic Liquid Waste Quality Standards. This study was aimed to understand whether phytoremediation treatment with water ferns (Azolla microphylla) could reduce BOD and TSS concentration of Timbul Roso Restaurant’s liquid waste by doing an experimental study with pre-post test control group design. Samples was obtained by using time composite method among the different times sequence of the production process to homogenized the waste. Afterwards, sample were treated and examined in the laboratory to record both parameters. The result later analyzed descriptively and statistically by using one tail paired and independent t-test. The results showed that des-criptively, the average BOD concentration decreased from 1724 mg/l to 610,33 mg/l or 64,12 %; and the average TSS concentration decreased from 2018,67 mg/l to 100,33 mg/l or 95,28 %. The corresponding statistic tests showed significant confirmation, i.e. p=0,0075 for BOD and p=0,0055 for TSS. Based on the results, it can be concluded that Phytoremediation treatment with Azolla microphylla is able for reducing BOD and TSS concentration from the liquid waste, however both parameters still have not met the requisite standards.

WHO declared tuberculosis (TB) as global emergency. In 2004, TB cases in Indonesia was esti-mated as much as 539.000 with 140.000 death every year. Based on the evaluation of the im-plementation of TB controlling program, in Yogyakarta City in 2011, two of national indicators had been achieved, i.e. Case Detection Rate and Error Rate. Meanwhile, several factors were suspected as the cause of the fail of the Recovery Rate and the Conversion Rate met the nation-al targets. This study was aimed to analyze factors related with the recovery of new positive BTA cases in Yogyakarta City by conducting survey which followed cross sectional design. As the respondents were 60 new cases of the post-medication program derived from 18 puskesmas throughout the city and sampled by using proportional cluster random sampling method. Data were collected by conducting interview, observation and measurement. Univariate, bivariate and multivariate analysis were employed to reveal the dominant factors. Bivariate analysis of Odds Ratio found that among the observed variables, house illumination and medication compliance were correlated significantly with the recovery of new cases. However, advanced multvariate analysis by conducting logistic regression test only found the medication compliance as the do-minant factor.

Activities in hospitals not only bring positive impact to general community, but also potential of reduce the quality of environment and public health, e.g. negative effect from the yielded waste. Based on the preliminary study on the liquid waste produced by Air Force Hospital Dr. Suhardi Hardjolukito in Yogyakarta, it was found that the concentration of TSS, ammonia and phosphate were exceeding the quality standard regulated by Yogyakarta Governor’s Decree No 07 in 2010. The aim of the study was to understand the effectiveness of the addition of coagulant consisted of lime and alum, with filtration media of 40 cm-thick quartz sand and 40 cm-thick zeolite in reducing the concentration of the three parameters by conducting a true experiment with pre-test post-test with control group design. The object of this research was the processed liquid waste from the hospital and the subsequent waste water sample were obtained by using composite sampling me-thod. The study was carried out in five replications and taken place at Yogyakarta Polytechnic of Health. Meanwhile, the examination of the parameters were conducted in Health Laboratory Office of Yogyakarta. The data were statistically tested by using one way anova, and the results showed that the coagulants and quartz sand could decrease the concentration of TSS, ammonia and phos-phate as much as 30,91 %, 39,32 % and 36,44%, respectively; while the coagulants and zeolite could lower the concentration of TSS by 46,89 %, ammonia by 68,37 %, and phosphate by 68,38 %). Because the following p-values gained from the statistic test were 0,003; 0,007; and <0,001; respectively, it can be concluded that the coagulant and the filtration media were significantly able for reducing TSS, ammonia and phosphate concentration in the liquid waste, and zeolite was de-termined as the most effective filter.

One of the organic waste generated from markets is pineapple waste. Parts of pineapple thatcan be eaten is only 53 % while the remaining 47 % were dumped as waste. The peels of pineapple contain 13,65 % sugar, so that can be processed as bioethanol, i.e. ethanol made frombiomass containing cellulose or starch component. The preliminary trial found that the fermentation of pineapple waste in four days with four weight variations of Saccharomyces cereviceaeobtained the highest level of bioethanol at 27,7289 %, i.e. produced from 15 gram of that yeastThe purpose of this research was to know the influence of Saccharomyces cereviceae weightvariation (0 %, 20 %, 40 % and 60 %) and fermentation time variation (4 days, 7 days and 10days) toward the levels of bioethanol produced from pineapple waste of Beringharjo Market, byconducting a post-test only with control group designed experiment. The results show that thehighest levels of bioethanol produced was 40,45354 %, i.e. from the use of 60 % weight of Saccharomyces cereviceae and 10 days fermentation. However, the statistical analysis with two-wayanova test at 95 % level of confidence yielded a probability value >0,05 which means that thelevels of bioethanol produced from those yeast weight variation and fermentation time variationare not significantly different.
