Abstract

The continuous use of hard water can cause health disorders as well as economic, aesthetic, and technical problems. According to the regulation issued by the Ministry of Health No. 416/Menkes/Per/IX/1990 about the quality requirements for clean water, the maximum levels permitted for water hardness parameter is 500 mg/l. Based on the preliminary study conducted at Griya Citra Asri Housing in Temuwuh Kidul, Balecatur, Gamping, Sleman, it was found that the water hardness of the dug well water had exceeded the threshold, i.e. 753,33 mg/l as CaCO3. This study was aimed to determine the effect of various doses of resin in decreasing the water hardness of the housing’s well water by performing a true experiment with pre-test post-test with control group design and following a simple random sampling method. The results showed that the average reduction of water hardness were 33,61%, 39,80%, 50.,89%, 60,27%, and 74,48% for resin doses of 15 mg/l, 20 mg/l, 25 mg/l, 30 mg/l and 35 mg/l respectively. The one way anova statistical test proved that the difference were significant (p<0,05) and it could be concluded that 20 mg/l was the most effective dose.

Abstract

Labors at weaving unit of textile industries work in an environment condition that is highly exposed directly to noise generated by the loom production machines. The purpose of this study was to know the implementation of health and safety efforts towards that noise’s risk factors at the weaving unit of PT Primissima, by conducting a research with descriptively survey approach. The study sample were obtained purposively, and by using a defined criteria of at least one year working period, 43 workers were eligible for being the respondents. Data were collected by interview and observation, and then were analyzed descriptively. The results of the study revealed that the noise intensity in the weaving unit did not comply the threshold, and the efforts that has been done consisted of: isolation at production room, provision of ear protectors devices by the company in the form of cotton and its use by the labors, periodic medical examinations were carried out once a year for those who were indicated had declining health condition, explanation ofthe job procedures at labor’s initial service, training of health and safety for labors who prospective to managerial carrier, and the provision of health insurance by participating in Jamsostek program. The efforts related with isolation, ear protectors tools, periodic medical check-up and HSE training, have not fulfilled the regulations; however, the explanation of work procedures as well as the health insurance provision, had been implemented appropriately.

Abstract

One of compulsory chemical parameters of water for sanitation and hygiene needs is hardness (CaCO3). One method to reduce water hardness is by ion exchanging This study used natural zeolite from Gedang Sari, Gunung Kidul; bentonit from Nanggulan, Kulon Progo, and zeolite from a chemical store. The study was a true experiment with one group pre-test post-test design, and was conducted in June and July 2018. The hard water samples were taken from Wonotawang Village RT 11 of Bangunjiwo, Kasihan, Bantul. The water treament were held in nine replications.The data were analyzed by using one way analysis of variance at 95 % confidence level.Descriptively, the average of hardness reduction yielded from Gunung Kidul’s zeolites was 50,90 %, from Kulon Progo’s Bentonite was 66,11 %, and from zeolite of chemical store was 56,19 %. Statistical analysis produced a p-value of 0,037 which means that in filtration process the three medias have significant different ability in reducing water hardness.
