Low back pain is one of the musculoskeletal disorders resulting from the wrong ergonomics. Such conditions can occur in the informal work sector, such as clothes tailors at the Martapura Bauntung Batuah Market. The purpose of this study was to determine the relationship of work position with complaints of lower back pain in clothes tailors at the Bauntung Batuah Market Martapura. This study is an analytical study with a cross-sectional approach. The sampling technique uses total sampling with criteria for male sex so that the number of samples is 43 people. Data will be analyzed using the x2 test (Chi-square). The results of the statistical analysis obtained the value of the work position p-value of 0,000 meaning that there is a relationship between the work position and complaints of lower back pain in the clothes tailor at the Martapura Bauntung Batuah Market. For other researchers, further research needs to being done on other factors such as individual factors and physical environmental factors that can cause complaints of lower back pain.
Abstrak: Effectivity of “Portable UV Disinfection” to Decrease Bacterial Number (Escherichia Coli Spp) in Drinking Water. Disinfection using ultraviolet ray is faster, more accurate and chiefer. This research aims to measure the effectivity of portable UV disinfection to decrease bacterial number (E. Coli) in drinking water. This research used true experiment methods with postest only control group design on laboratory scale. Drinking water contained E. Coli taken from wheel then disinfected by ultraviolet ray. Variation of treatment included variation of water depth 10, 15, dan 20 cm and variation of detention time 0, 1, 5, 10, dan 20 minutes. The result show ultraviolet ray been able to kill E. Coli in drinking water. Removal efficiency of E. Coli at 10 cm water depth with 0, 1, 5, 10, and 20 minutes detention time were 0,0%, 75,0%, 76,2%, 98,0%, and 98,3% particularly. At 15 cm water depth, removal efficiency of E. Coli were 0,0%, 36,3%, 58,2%, 68,0%, dan 89,0% particularly. At 20 cm water depth, removal efficiency of E. Coli were 0,0%, 56,1%, 77,5%, 83,9%, dan 88,1% particularly. Statistical test showed the number of killed bacteria based on detention time was difference significantly. The longer time to be flashed the killed bacterial more. Flash of ultraviolet ray with lumination be able to kill the bacterial more effective.Key Words : Portable UV Disinfection; E. Coli; drinking water
: Human Factors With The Occurrence Of Work Accidents In Industry Center Of Aluminium Furniture Regency Hulu Sungai Utara . Work accident do not happen by accident but there is. The first group is categorized the 80-85% of the human factor and 20-25% because to mechanical/environmental factors. Human factors that can lead to the occurrence of accidents is worker characteristics (age, education level, work period, and job training), less concentration workers, work discipline (APD) and psychological factors (marital status). The purpose of this analytic research is to know the relation of human factors with the occurrence of accidents. This type of research analytic with cross sectional design. Population of research to 43 people. Data analysis used X2 (Chi Square). The results showed that once a work accident. Many accident as 40 people. The type of accident is slipped (11.6%), punctured (48.8%), cut throat (32.6%). Location of the wound (69.8%). The results showed that there is a relationship of age and educational level (p <0.05) with the occurrence of accidents. Control means with makes a comfortable working space, rest enough schedule, procurement of personal protective equipment (PPE) in accordance with the hazard potential Keywords: human factors; occupational accidents; industry Aluminum furniture
<p style="text-align: justify;">Humans in meeting the needs of water should pay attention to aspects of quality and quantity. Particularly the aspect of bacteriological quality, because contaminated water can cause waterborne disease. One of the clean water facilities used by the community is the well. The community of Sungai Ulin Kota Banjarbaru uses wells for daily activities. The purpose of this research is to know the bacteriological quality and the level of risk of water pollution wells Sungai Ulin Kelurahan Kota Banjarbaru. The research type is descriptive and cross-sectional research design. The population of this study was all wells in three Rukun Tetangga (RT 19, RT 20 and RT 21) of 40 and samples of bacteriological quality of well good water. The result of the research is the characteristic of respondent from the level of education of most elementary school is 19 (47.5%), knowledge level 21 (52,5%), middle income category (1-3 million / month) 36 (90%) and length of stay Respondents old category (> 10 years) as many as 39 (78%). The conclusion of the study showed that the quality of bacteriologic (MPN Coli) of well water 3 (7.5%) was eligible and 37 (92.5%) were not eligible. The level of risk of contamination of wells to 40 wells, among others, for very high risk of 6 units (15%), high risk of 26 units (65%), medium risk 5 pieces (12.5%) and low risk 3 (7.5%). Need to do research about the relationship of good construction with bacteriological quality of good water.
Low Back Pain (LBP) is one of the musculoskeletal disorders, psychological disorders and the result of wrong mobilization. LBP is one of the most common health problems in the industrial community, one of which is Payet Craftsmen. The purpose of this study was to determine the relationship between age and work position with LBP complaints on Halidah Sequin Craftsmen in Cempaka Sub-District.
