Abstract

One of environmental issues that still a problem is waste. One of the waste sources is rempeyek industry in Pelem Madu, Imogiri, Bantul, Yogyakarta Province that produces solid waste in the form of peanut shells and has not yet been processed adequately. Peanut shells contain of 63,5 % cellulose which can be used as additional component in paper recycling process. The purpose of this research was to know the effect of five composition ratio of peanut shells towards the tensile strength and water absorption of the recycled papers, by conducting an experiment which followed post test only with control group design. From the measurement of paper tensile strength, the averages from five times replication for each composition ratio between used papers and peanut shells (i.e. ,1:0,5; 1:1,0; 1:1,5; 1:2,0; and 1:25) were: 0,519 N/mm; 0,751 N/mm; 0,777 N/mm; 0,905 N/mm and 1,118 N/mm, consecutively. Meanwhile, the obtained means from water absorption test for the same composition ratios, were: 71,4 mm; 72,2 mm; 72,8 mm; 65,2 mm and 57,2 mm, respectively. The One Way Anova test at 0,05 level of significance, yielded a p value < 0,001 which means that the composition ratio variation significantly influenced the tensile strength and the water absorption of the yielded papers. The best composition ratio for both parameters is 1:2,5 and it can be concluded that the more peanut shells were added to the process, the produced paper will gain the higher tensile strength and the more able to reduce water absorption.

Abstract

Dengue haemorrhagic fever is a dangerous disease because may lead to death within a relatively short time. The disease is caused by dengue virus that enters human body through the bite of Aedes sp mosquitoes. DHF prevention activity is done by sowing larvicidal granule in water reservoirs that are difficult to clean. Larvicide that is often used by people to eradicate Aedes sp larvae is abate (temephos 1 %). The purpose of this study is to determine the effectiveness of the larvicide application of temephos 1 % with membrane system using paris fabric, compared with the sowing system. The type of the research was an experiment employing post-test with control group design. The sample size of Aedes sp larvae was 1350 in the form of instar III and IV larvae or aged 4-6 days after hatching. The calculation of larvae mortality was conducted after 24 hours contact with temephos 1 % and was performed every two weeks in three months. The data obtained were analysed by using independent t-test at 95 % of confidence level. Theresults show that the mean mortality percentage due to the application of temephos 1 % with membrane system at bi-weekly observation (first to sixth) were 100 %, 94 %, 80 %, 68 %, 35 %, and 23 %, respectively; while the results from the sowing system as comparative positive control were 100 %, 86 % , 37 %, 23 %, 12 %, and 6 %, respectively. Descriptively, based on the graph of larvae mortality difference, it can be concluded that membrane system application is more effective than the sowing system. However, statistical analysis toward the mortality data of the bi-weekly observation from the first to the sixth found that the percentage difference is not significant (p-value = 0,298).

Abstract

Cassava peel waste which is not handled properly will become breeding sites for bacteria and germs that will cause health problems. To reduce the negative impact, since cassava peel still has enough nutrient content, it can be reprocessed as flour. The purpose of this study is to determine the differences in shelf-life and acceptance of physical properties (color, odor, texture) of cassava peel flour made from four sanitation treatments by using 10 stages of processing. The type of the research was an experiment with post test only design. Data analysis was conducted descriptively and analytically with one way Anova test at ? 0,05. The conclusion of this studyindicates that the averages of physical acceptance of cassava peel flour between treatments P1, P2, P3 and P4 with formulation F1 to F6 are significantly different. In treatment P3, formulations F3, F4 and F5 are those that can replace wheat flour by 20-60 %; and the differences in shelf-life of cassava peel flour between treatments P1, P2, P3 and P4 ae also significant. By using ESS calculation method, the longest shelf-life is treatment P1, i.e.120 days and 18 hours.

Abstract

The measurement of wall microbe number in the laboratories of Environmental Health Department of The Polytechnic of Health of Yogyakarta was 70,9 CFU/cm2, which did not comply with the quality standard regulated by The Ministry of Health’s decree No. 1204/Menkes/SK/X/2004 about Health Requirement for Hospitals, i.e. 0-5 CFU/cm2. One of the efforts that need to be applied is disinfecting the laboratories’ rooms. The study was aimed to know whether 20 % concentration garlic extract is able to reduce the germ numbers of the walls. This study was a pretest post-test designed experiment. The sample were taken at five different laboratories, and for each laboratory there were four sampling points. The sampling technique used sterile cotton stick that were swabbed on a 10 cm x 10 cm wall surface and then were dipped into 10 ml PBS.The result showed that garlic extract with 20 % concentration can decrease the germ number ofwalls to 32,35 CFU/cm2, or in average of 38,6 CFU/cm2 (54,4 %).

Abstract

Dengue Hemorrhagic Fever (DHF) is a health problems that tends to increase, in terms of the case number and the spread. Elementary school students are the vulnerable groups for this disease. Therefore, health education to uplevel their knowledge about the eradication of Aedes’ breeding places should be conducted. One of the methods is through traditional games as the media. The purpose of this research was to know the effect of Engklek game and lecture on the knowledge level of preventing DHF among students of Krekah Elementary School of Bantul. Thestudy was a quasi experiment with non-equivalent control group design. The study subjects were 82 students of IV grade, who were assigned into 2 groups, i.e. 41 as the experiment group and 41 as the control group. The data were analyzed by using Mann-Whitney test at 0,05 level of significance. Results of the study show that Engklek game as health education media is significantly able to improve students’ knowledge (p-value = 0,001), i.e. about 18 %.

Abstract

Fly is one of insect vectors which can transmit microorganisms causing sto- mach diseases such as typhoid, cholera and dysentery. Tuber of Dioscerae hispida D can be used as an alternative for biological insecticide that are safer for the environment, and so that can replace the common inorganic ones which are not environmentally friendly. They study was aimed to understand the influ- ence of various concentrations of Dioscerae hispida D extract spraying towards the mortality of fly at the temporary waste disposing site of Sentolo Market of Kulonprogo, as well as to understand which concentration is the best. The study was an experiment employing post test only with control group design. Tubers of the plant were obtained from the surrounding area. The results using one-way Anova test show that the effect of various concentrations of the insecticides were significantly different (p<0,001). Since the most effective effect is gained from the 44,4% concentration, it is suggested to use this concentration for con- trolling the annoying fly. Further effect of the insecticide on other disease vec- tors such as mosquito and cockroach, may be explored.
