Abstract

ABSTRACT Diarrhea is one of public health’s problem with high mortality and morbidity rate especially among children under five years old in Indonesia. There were 158 cases of the incidence of diarrhea in Lingkungan I Kelurahan Paya Pasir Kecamatan Medan Marelan Medan city in 2014. The aim of this study was to analyze the relationship between the density of flies, personal hygiene and basic sanitation with the incidence of diarrhea in children under five years old. This study method is analytical survey with cross sectional design. Samples were chosen using total sampling technique, that there were 77 children under five years old and the mother as a respondent. The density of flies is measured by using fly grill, personal hygiene were obtained through interview using questionnaires and the datas of basic sanitation is collected through direct observation using basic sanitation’s observation sheets. The study result that there were found 33 children under five years old got diarrhea in the last one month (period of April to May 2015). In chi square test results obtained the value of p=0,044 and PR=1,387 for the density of flies variable, p=0,003 and PR=1,623 for personal hygiene variable and p=0,034 and PR=1,158 for basic sanitation variable. The high density of flies can be caused by bad environmental sanitation. Washing hand’s habit using soap among respondent is very poor. That was because most respondents have last educated in junior high school and lack of knowledge about personal hygiene. The basic sanitation owned by respondent mostly in the category of unqualified health. The conclusion is there are a correlation between the density of flies, personal hygiene and basic sanitation to diarrhea in children under five years old. It is advisable to the respondents (mother of children under five years old) to be more concerned about their own personal hygiene and their children. Sanitation Office and the goverment is suggested to be more concerned to citizens who live around disposal area of garbage Terjun especially in basic sanitation’s condition.

Abstract

ABSTRACTScavengers are groups of people who seek and collect solid waste that still has economic value. The scavengers usually take out the waste in the trash while or in landfill. Supervisory of the landfill was originally not allow scavengers to collect waste in the landfill because they can be exposed to sharp objects and disease. Over time, the scavengers eventually left to work at the landfill. Number of scavengers in TPA Terjun today is 500 people. The role of scavengers at the landfill is still unknown whether it can help reduce landfill waste in the landfill.This research is a descriptive research with quantitative analysis. The goal is to find out what the role of a scavenger in the management of waste in the landfill. The sample size observed was 30 people.The research result shows that the volume of waste that goes into TPA Terjun every day was 3.868,57 m3 while the amount of waste that can be managed by scavengers every day is 89,02 m3. Thus, the volume of landfill waste left in TPA Terjun every day was 3.779,55 m3.The conclusion from this study is that the scavenger role in waste management and solid waste generation did not show a reduction in the volume of landfill waste in TPA Terjun. Ability scavengers in reducing the volume of waste in TPA Terjun only by 2,3%. Thus, the percentage of residual landfill waste in TPA Terjun every day is 97,7%.The government should develop a technology that not only destroy the waste but also making use of waste as alternative energy sources as well as supporting the role of scavengers in reducing waste in TPA Terjun, Medan.Keywords : Scavengers, Waste Management, Volume of Waste

Abstract

ABSTRACTDiscomfort can occur in the environment of school, one of them is thenoise. Noise that occurs when subjects ongoing impact on the learning process,which is one of the disruption of the concentration of students. The research wasconducted at the State Primary School 067240 Medan Tembung District whichaims to find out the difference in the level of concentration towards the studentsbefore and after the noise due to railway crossings.This method of this research is pre-experimental design by using onegroup and pre-test post-test. The sample of this research is also using purposivesampling technique which consists of 58 students. The level of noise wasmeasured by using a Sound Level Meter and level of concentration of studentswas measured using a Stroop Test. Data analysis is using non-parametricstatistical tests (Wilcoxon tes t) and Parametric Test (paired t-test) at the 95%significance level.The results showed that in general the average noise level in theclassroom before and while the train passed the railway crossing exceeds thequality standards that have been established in the amount of 55 dB. Other resultsalso showed that the results of interference score of students before the railroadcrossing with a mean of 13,59 and after the railway crossing at 17,40. Thisindicates that the concentration of students has decreased when compared withpretest posttest. Based on the test results of wilcoxon test is known, there are thedifferences in the level of concentration towards the students before and after thenoise due to railway crossing (p. = 0,001).Based on the results of this research are expected to the school in order toreduce the noise while is coming from the rail traffic. Such as the installation ofblind or curtain on the window class, the use of firm window on the outside walltowards the class which is passing of the train tracks, and the use of noisedampening vegetation.Keywords: The level of the noise, Concentration of the students, Stroop Test,Sound Level Meter
