One of the alternatives for overcoming the excessive run-off and groundwater deposit problems is by infiltrating water beneath the ground. The infiltration process depends on soil textures, such as loamy soil has small porosity, while sandy soil has higher porosity. The study is aimed to reveal the effect of the depth of percolation holes between sandy and loamy soils towards their pene-trating capacity. This was a pre-experimental research employed post test only design, and located at Sukunan Village, Gamping, Sleman Regency for the sandy, and at Gedongan Sumberagung Village, Moyudan, Sleman Regency for the loamy one. Results of the study show percolation rate average of sandy soil for 50, 100 and 150 cm hole depth variation were 0.593 cm/minute, 1.565 cm/minute, and 2.529 cm/minute respectively. The p-value obtained from the one-way Anova test was <0,001, which means that the penetrating capacity among the depth variation was significantly different. Results for loamy soil for the same depth variation were 0.396 cm/minute, 0.582 cm/minute, and 0.914 cm/minute, respectively, with the corresponding p-value was <0,001 as well. The sub-sequent LSD test produced p-values of <0,001 for all depth pairs comparison, as well as the result of t-test for comparing the difference between sandy and loamy soils. Based on the results it can be concluded that the highest percolation rate is for sandy soil at 150 cm hole depth.

In order to fulfill human needs, food production usually generates wastes as the byproduct. Cassava is one example of mass consumption food which yield waste from its peels. Since cassava peel has high carbohydrate content, to minimize the negative impacts of the waste, it can recycle into flour and be utilized as one of food ingredients wet noodle making. The purpose of this research was to know the color, smell, taste and texture produced by wet noodle which were consisted of 0%, 20%, 40%, 60% and 80% flour skin formulation, and threfore the best formulation can be identified. This study was an experiment with static group comparison design. As the panelist, five housewives were appointed to examine the noodles variation, and their cum-mulative scores were subsequently statistically analyzed. Results of the study showed that the p-value obtained from one way anova test was 0,001 which means there are differences across formulation variation, and the most accept-able cassava peel formulation was 20%.

The use of meat grinding machine produce sound with high noise intensity which can be harmful for the health and safety of workers operating the machine. Based on a preliminary survey con-ducted in 5 February 2013 at a meat shop belongs to Mr “X” located in Serangan Market of Yogyakarta, it was known that the noise intensity yielded from the grinding machine was record-ed as high as 100.4 to dB (A). Hence, this condition needs efforts to reduce the noise in order to prevent health effects which can be caused by long term and execessive exposure. One method that can be applied is by utilizing chicken feathers waste as noise reducer, and this study was aimed to determine the influence of thickness variation of the feather by doing an experiment with pre-test post-test control design. The wooden box muffler containing chicken feathers and covered the machine was made from sengon wood and laminated by plywood. The noise mea-surement were carried out in six replications for each feathers thickness by using sound level meter following the standard measurement and calculation. The results of the study showed that the feather thickness variation of 10 cm, 20 cm and 30 cm, were corresponded with in average of 14,9 %, 16,0 % and 17,5 % noise reduction, respectively. Analysis by using one way anova sta-tistical test at 95 % level of signifcance, found that the differences among the amount of the reduction were significant, and therefore it can be concluded that feather can reduce the machin-al noise level. Subsequent LSD test found that the 30 cm thickness was the most effective.

Waste management can involve the entire community, including children. The involvement of very young children is a good first step for them to learn how to handle waste and to be respon-sible for caring the environment. The average age of Kudup Sari Kindergarten’s students, which is located in Sidoluhur, Godean, Sleman, is 6 years old. Children at this age are in the stage of imitating and receiving new knowledge easily. Therefore, it is expected that the children can easily apply the new received knowledge. This study was aimed to reveal the most preferred model of trash picking device among kindergarten children by conducting a quasi experiment which employed post-test only design. The population and sample of the study were all 41 stu-dents in the Class B of Kudup Sari Kindergarten. The observation was held in 10 times to ob-serve the number of children who pick the trash up that using the two picking models. Des-criptively, the difference of frequency average of trash picking is obvious, i.e. 4 times with the piercing model against 37 times with the clipping model. The result of independent t-test at 95 % level of confidence confirmed the difference since the obtained p-value that was smaller than 0,001, showing a significant disparity between the two averages. Therefore, this study shows that the clipping model is much more preferred by Kudup Sari Kindergarten students to pick trash than the piercing one.

Poor controlling mechanism on industrial waste have resulted in very wide pollution, such as li-quid waste containing Pb from batik making industries. Rivers that have been polluted by Pb compounds or ions which exceed the threshold concentration may result in death for aquatic bio-ta. Batik industries in Pilangkenceng has never conducted wastewater treatment. One of the treatment methods that can be applied is by using phytoremediation plants. The purpose of this research was to know the effectiveness of water spinach (Ipomoea aquatica) in decreasing the concentration of lead (Pb) in batik waste water, by conducting a pre-test post-test with control group designed experiment held in December 2017 to February 2018. The study results show that the average of Pb concentration before the treatment was 0,252 mg/l, and by adding five stems of water spinach, the concentration decreased 0,001 mg/l; adding 10 stems of spinach, decreased 0,077 mg/l; and adding 15 stems spinach, decreased 0,112 mg/l. Data analysis with one way anova statistical test at ?=0,05 shows significant difference among those decreases (p-value <0,001.

Solid waste in the form of used jerrycans in Wates Local Public Hospital is comprised of twotypes, i.e. the 5 L jerrycan which was contained acid liquid and the 10 L jerrycan which was contained bicarbonate fluid. In a month, the number of used jerrycans may reach 300. The changeof the jerrycans into safety boxes is one of the innovations to take advantage of the existingjerrycan waste in the hospital. Eventhough those two substances contained in the jerrycan arealmost similar with infusion fluid, they are not classified as hazardous waste as long there is nocontact with patients. This study was aimed to know the receptivity of respondents, i.e. consistedof 38 nurses and 9 cleaning service officers, toward the safety boxes which made of cardboardand those which made of used jerrycan as well, by conducting a prospective designed survey.The data were analysed by using dependent t-test at ? = 0,05; and gained p-value less than0,01; which can be interpreted that the receptivity between the two types of safety box is significantly different. Therefore, the conclusion is the used jerrycans yielded by the hospital can beutilized to replace the existing cardboard safety boxes.
