Improper handling of household organic wastes can causing serious problems on humans and the environment. One effort to solve the problem is by com-posting. However, since composting takes a long time, the processs needs materials as activator or inoculant to quicken the time needed. This study used liquid inoculant from tape yeast and tempe yeast at the same dose, to understand which one is the most effective. This research was an experiment with post test only with control group design. The organic wastes were taken from house-holds of Sukunan Village in Gamping and Ngabean Village in Pandak by following quota sampling method. The average time of composting in the control group was 53,8 days, while in the treatment group 1 was 19,93 days (33,93 days faster compared with the control) and in the treatment group 2 was 23,67 days (30,13 days faster compared with the control). The com-posting time data were analyzed by using Kruskal-Wallis test at 0,05 significance level; and gained p-value <0,001, which means the difference composting times among groups were significant. The subsequent Mann-Whitney test obtained p-values<0,001 for all pairs comparing, therefore it can be concluded that tape yeast liquid inoculant is more effective than the tempe one in accelerating the composting time.

Cow dung in Kadipaten Village of Kedungjambal, Tawangsari, Sukoharjo had not been managed appropriately. Actually, the organic substance contained in cow dung is potentially used as raw material for biogas making. To accelerate the time needed in the biogas processing, biostarter can be added such as pineapple peels waste. The aim of the study was to identify which biostarter concentration is the most effective. The study was an experirmental one with laboratory scale and followed post-test only with control group design. In each biogas digester tank which made of 50 litre volume jerrycan consisted of 14 litre fresh cow dung, 23,4 litre dilution water and 2,6 litre pineaplle waste bio-starter concentration. The concentration variation of the biostarter were 20%, 40%, 60%, 80%, 100%. The biostarter was made by fermentation process in two times of 24 hours from the mixture of pineapple peels, tempe, banana, onion and sugar solution. The results showed that the mean volume of biogas yielded by the control group was 140 mm3, and in the 20%, 40% and 60% concentration groups were 794,0 m3, 859.7 mm3 and 925,0 respectively, but with negative flame test. Meanwhile, in the 80% and 100% concentration groups, the volume of biogas produced were 1107,0 mm3 and 1307,7 mm3 in average and show two and four minutes flame time respectively. The statistical analysis with one way anova test concluded that biostarter made from pine-apple peel waste affecting the yielded biogas volume and the most effective concentration was 100%.

Dengue Hemorrhagic Fever (DHF) is an infectious disease caused by dengue virus and spread by Aedes aegypti and Aedes albopictus mosquitoes. Among the 14 kecamatans in Yogyakarta City, Ngampilan was one of the highest cases of DHF in 2011, i.e. 38 cases. This study was aimed to understand the factors related with those DHF incidence by conducting an obser-vational study employed case-control design with retrospective approach. The number of study subjects in both the case and control groups were 38. Data were obtained through interview and observation. Odds Ratio and logistic regression were used to analyse the data. Results from bi-variate analysis showed that among the observed variables, those which were significantly cor-related with DBD incidence were: the presence of mosquito larvae habitat, and age, attitude and prevention behavior of respondents. Furthermore, multivarite analysis revealed that the most do-minant factors were the existence of mosquito larvae habitat (OR=4,526, 95 % CI=1,352-13,372, p=0,006); and respondents’ age (OR=4,645, 95 % CI=1,263-17,088, p=0,021). People aged less than 15 years old and close with Aedes larvae’s habitat have probability of getting DBD as much as 31,32%.

Because their activities need water, beside producing specific products, some industries also yielding waste water as by-product whose quantity will corresponds with the quantity of the raw water. If the waste water is directly discharged into the environment without appropriate treat-ments, it will causing environmental pollution. Based on the preliminary test results, the level of BOD in the waste water effluent of the Central Tofu Industry in Trunan Village in Magelang were measured as much as 1259 mg/l and 860 mg/l, and so that, had not fulfilled yet the threshold ruled by the government of Central Java Province, i.e. 150 mg/l. One of the methods which can be used to process the waste water is by applying biostarter containing microorganisms for de-grading the existing organic substances. The study was aimed to determine the differrence of the reduction of BOD level resulted from three different detention times in the waste water treat-ment using biostarter “X”, through conducting a laboratory scaled pre-test post-test designed experiment. 15 tofu industries were sampled by using simple random technique, while the waste water sample from those industries were obtained by following the standard procedure. In each observed detention time, five different industries were placed. The results showed that the de-tention time of 7, 8 and 9 days, were able to decrease BOD level in the average of 27,0 %, 59,9 %, and 76,9 % respectively. One way anova test at 95 % significance level confirmed that the differences were significant, and the subsequent LSD test found that 9 day detention time was the most effective method. Further study for gaining more applicability of the study results is suggested to conduct a real field-scaled experiment.

One objectives of health development is to improve the ability of healthy life for everyone in order to reach their optimal health degree. There are some physical factors that influence public health, e.g. inadequate illumination. Inappropriate illumination can disturb the health of eyes. The goal of the study was to understand the appropriate level of artificial illumination used for reading activities in Al-Qodir Moslem Boarding School at Tanjung Village, Wukirsari, Cangkringan, Sleman. The study was an experiment with ’post-test only design’. The study subjects were high school level students. Meanwhile, the treatments were 100, 200 and 300 lux artificial illumination. The subjective eyes fatigue symptoms were observed by using questionnaire and then classified as: high, medium, and low. For each illumination treatment, the procentage of the symptom classifications are as follows: 100 lux: high 53,3%, medium 33,3%, low 13,4%; 200 lux: high 13,5%, medium 20,0%, low 66,5%; and 300 lux: high 40,0%, medium 40,0%, low 20,0%. Based on the results, it was concluded that the appropriate illumination intensity for the boarding school was 200 lux, because this treatment was the highest procentage in the low ’category’. Furthermore, it was advised for school managerial board to provide the requisiteillumination by installing 40 watt flourescent lamps or providing 14 watt table lamps; and to avoid excessive glare, the installation should carefully considering the appropriate distance between the lamps and reading areas.

To suffice the demand of energy consumption, alternative fuels is needed to be developed, suchas bioethanol. Bioethanol is chemical solution which is produced from various plants, fruits, or any part of plant which contain starch, glucose and cellulose. Jackfruit rind has 14,752 % glucose, where from the preliminary test, with Saccharomyces cereviceae addition, the fruit waste could be fermented for producing bioethanol. The purpose of this study was to know the effect of various weights of Saccharomyces cereviceae (i.e. 0%, 25%, 50% dan 75%) and variation fermentation durations (i.e. 4,5 days, 7,5 days, and 10,5 days) of jackfruit rind toward the concentration of the yielded bioethanol by conducting a post test with control group designed experiment. The maximum concentration of bioethanol obtained was 5,63731 % which was produced by using 50% of Saccharomyces cereviceae and from 7,5 days fermentation. The statistical analysis test using one way anova test at 95% level of confidence, concludes that the differences among the ethanol concentrations produced by those various Saccharomyces cereviceae weight and fermentation time are significant.
