Abstract

The objectives of the study were: to understand the number of applicants who chose Environmental Health Department (JKL) as their first choice, the average of applicants’ high school’s passing grade (NEM), and the average grade of their selection test. The study was aimed as well to reveal the relationship between those three factors with the Cummulative Achievement Index amongst JKL’s students. To attain its objectives, the study employed a cross sectional survey by collecting the corresponding data during the academic year between 2004/2005 and 2006/2007. The results showed a strong relationship between those three factors with the achievement of the students, of which the NEM was the biggest contributor. It was suggested that in the future the new student selection method could use the NEM selection only, since it is relatively more effective and efficient compared with conventional written test.

Abstract

Dengue Haemorrhagic Fever (DHF) is one of the major health problem in the period of 2005 to 2025. Therefore, it is urgent to find the ways to solve this problem as so many people got this disease every year. The purpose of the research was aimed to reveal the relationship between the knowledge level of DHF disease, the action level of DBD controlling as well as the existence of the corresponding Aedes aegypti larvae, with the endemicity level in the Dlingo I Community Health Centre. The study employed survey method with cross sectional approach in two villages i.e. Dlingo and Mangunan which represents endemic and sporadic areas respectively. The interviewed respondent of this study was housewives and the data needed were collected by using questionnaire and also checklist to observe the mosquitos. By conducting chi square and pearson correlation test, the study concluded that endemicity was not correlated with knowledge level (p-value 0,164). However, the endemicity were associated with both the controlling action (p-value 0,029) and the mosquito existency (p-value 0,001). Based on this findings, in order to prevent the occurence of DBD in the future, it was suggested that people have to revitalize the 3M program and the eradication of the mosquitoes’ breeding places. It was advised as well for DBD control counsellor to improve and to increase the health education program and to organize people who responsible in observing the existence of mosquito larvae amongst the community.

Abstract

The study was aimed to understand the influence of processing liquid waste from “Darky” chicken abbatoir by using neutralization, bee-hive model anaerobic and aerobic biofilter, and sedimentation chambers towards the decrease of BOD and TSS concentration; and whether the decrease comply the requisite tresholds regulated by Yogyakarta Province. The study conducted pre-test post-test with control design. Integrated and composite methods were used to obtain 240 liters liquid waste sample. The collected data were tabulated and descriptively analysed; as well as statistically analysed by using unpaired t-test at 95% confidence level. The results show that in experimental group, BOD was reduced from 1070,61 mg/l to 88,68 mg/l or 91,72%; and TSS was reduced from 1222,17 mg/l to 63,13 mg/l or 94,83%. Both parameters have fullfiled the above standards. Subsequently, the statistical test also shows strong evidence that in experimental group the reduction were significantly different with those in control group The study suggests that the model can be used as an alternative method for processing liquid waste from chicken abbatoir. However, in its application, further adjustment regarding to the debit of the liquid waste should be considered.

Abstract

The liquid waste yielded from soybean curd industry owned by Mr. Sudaryanto has not been adequately processed before discarded into water body. As the result, some people who living nearby felt annoyed. On the other hand, the li-quid waste contains relatively high organic substance which can be utilized as raw material for bio gas production. The objective of the study was to produce bio gas from the utilization of soybean curd liquid waste. It was expected that the bio gas would have similar characteristics with those made from cow manure. By using “Post Test Only Control Group Design”, the collected data from this true experimental study was analyzed descriptively, as well as analytically by using unpaired t-test at 0,05 significance level; meanwhile, to analyze the results two parameters were selected i.e the time needed to forming and the quantity of the bio gas. As the results: there was no difference between the time needed to forming the bio gas made of soybean curd liquid waste and that of cow manure (p-value = 0,069); however, there was a difference between the quantities of the bio gas made of both raw materials (p-value = 0,036).

Abstract

Motorcycles and cars derived from technology development, apart from their advantages as transportation vehicles are contributing to emit pollution gases such as carbon monoxide (CO) to environment. Another source for CO emission is repair shop. In order to decrease CO pollution from that place, this emission catchment tube with double filter was developed. The tool consists of activated carbon and glass wool as the adsorbent filter agents. The study used a 100 cc 4-strokes motorcycle as the source of CO emission and auto check 974/5 for measuring the CO concentration. Both descriptively and analytically, the results showed that the tube was able to decrease the pollutant concentra-tion (p value 0,016). However, it is suggested that any follow-up studies should explore the other possible material of the adsorbent, as well as the effective saturation time and the effective amount or number of the the filter.

Abstract

Rivers as water body, for Yogyakarta’s people who are living nearby are used as one of the clean water sources to fulfill their daily needs. This study was aimed to understand and reveal the measurement of some field parameters as well as the laboratory ones of five rivers which crossing Yogyakarta. There were three measuring points for each observed river. The results showed that for following parameters: i.e. BOD, DO, pH, TSS, and temperature; the measurement still meet the standards stated by the government regulation No. 20/1990 about the tresholds for water quality of type B water. Those findings may be affected by the aeration process generated by small basins existed in some places, and also by the dilution process caused from additional debit of small rivers which ended at the rivers. However, as the MPN coliform was very high and had not fulfilled the requisite, it showed an indication that the rivers are contaminated by human excreta and so that they are not safe for clean water source.
