Abstract

Function disorders were generally occurred due to individual factors and environmental factors. One of the industries that experienced a lot of development was PT. Semen Batu Raja which is located in Kelurahan Way Lunik. Dust particles with a size of fewer than 50 microns that normally fly can enter the workers' respiratory tract by being sucked in during breathing (ILO, 1998). Public Health Center of Way Lunik mentioned that the prevalence of ARI that occurred during 2016 amounted to 243 cases. The purpose of this study was to determine the relationship of cement dust levels to vital lung capacity in the community around PT. Semen Batu Raja in 2017. The research method was cross-sectional design. Independent variable was humidity of the house, room temperature, ventilation, smoking habits, gender, age, length of stay, and knowledge. While the dependent variable was lung vital capacity. Based on the results of the study, of the 145 Panjang community respondents around PT. Semen Batu Raja obtained 82 respondents who were diagnosed with pulmonary function disorders. Factors that have a significant influence to pulmonary function disorders were ambient dust levels with mean value 171.5 µg / Nm3 (0.025), home ventilation with mean value ≥ 10% (0.041) and smoking history of respondents with the greatest risk was active smokers. Other factors that were not statistically related were house humidity (0.041) mean 63.2%, house temperature (0.654) mean 29.5⁰C, gender, length of stay (0.82), and knowledge (0.654) This study is expected to be reference studies and studies for several parties.

Abstract

In areas that have not received clean water services, residents usually use well water, river water which sometimes even often the water used does not meet the standards of healthy clean water. To treat well water/ ground water is usually the community. build a processing unit in the form of a sand filter. The problem that is often encountered in treatment is cleaning the filter media. This condition is often difficult for the community to do because it requires time and energy, resulting in the sand filter that is supposed to be operational continuously and finally stops and is not even used at all. To overcome this problem, it can be done by improving the design of water treatment units with a system of combination of aeration and upflow flow filtration. This study is to determine the ability of the tool to improve the quality of shallow groundwater in terms of turbidity, Fe, Mn, color and odor to clean water and saturation point of filtering. Research Design is a "quasi-experiment" in the form of "Time Series Design" using a "pre and post test" design without control. The tool is designed in the form of an application prototype to determine its ability to reduce turbidity, Fe, Mn, color and odor and the length of saturation point. The results showed that iron content before processing 2.12 after processing 2,058. pre-treatment manganese content 0.080 after processing 0.078. Color and smell before color processing and odor after processing are colorless and odorless. Microbiological quality for stool coly before processing week 1 32 after treatment 0, week 2 coly of feces before processing 26 after processing 0 and weeks 3 coly of feces before processing 21 and after processing 0. Length of processing up to saturation point filter media total contact time processing is 30 minutes.
