The population was 12 employees who worked in the Power House division of PT. Humbahas Bumi Energi, using total sampling technique. The result of the research showed that the average noise in the Power House division of PT. Humbahas Bumi Energy was 95 dBA (exceeding the threshold of 85 dBA). The result of work stress symptom showed that 3 respondents (25%) were in mild stress category, 7 respondents (58,3%) were in moderate stress category and 2 respondents (16,7%) were in severe stress category. The result of Spearman correlation test showed that the significance value (2-sided) was 0,001 (p ≤ 0,05) which indicated that there was significant correlation between noise exposure and work stress symptom. The result for analytic test in the Power House of PT. Humbahas Bumi Energi at the r value = 0,851 and contribution among the variables was 72,42%. The conclusion of the research was that there was significant correlation between noise exposure and work stress symptom in the employees in the Power House division of PT. Humbahas Bumi Energi.

The measurement of heat stress was conducted by using Questtemp.It were found that 5 workers had heat stress qualify and 23 workers did not. The measurement of worker's pulse was conducted by using palpation method with stopwatch. It were found that before and after work, 6 workers had normal pulse and 22 workers had increase pulse. The result of statistic test showed that there was significant correlation between heat stress and worker's pulse in the workers at PT Perkebunan Nusantara IV Bah Butong Plantation, in 2015.

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

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.
