The Improvement of Work Posture Using Rapid Upper Limb Assessment: Analysis to Decrease Subjective Disorders of Strawberry Farmers in Bali
Scientific and Literature Open Access Publishing, 2016Co-Authors: Yusuf M., Adiputra N., Sutjana I. D., Tirtayasa K.Abstract:The workload was predicted based on work pulse that was measured using 10 beats method on the radial artery with a stopwatch. The indication of subjective disorders was measured based on the farmers\u27 general fatigue and musculoskeletal disorders before and after work. General fatigue was measured using 30 Items Self-Rating Questionnaire Industrial Fatigue Research Committee from Japan Association of Industrial Health, while musculoskeletal disorders were measured using NIOSH Nordic Body Map Subjective Filling. Environment temperature was measured using Sling Psychrometer. The noise was measured using Gossen\u27s sound level meter. Statistical analysis to find out the mean difference of the data before and after work was analyzed using t-Paired test with significance level of 5%. RULA result recommended changing from bending work posture using the old tool into standing work posture using new hole maker

the improvement of work posture using rula rapid upper limb assessment analysis to decrease subjective disorders of strawberry farmers in bali
International Research Journal of Engineering IT and Scientific Research, 2016Co-Authors: M Yusuf, Nyoman Adiputra, Dewa Putu I Sutjana, Ketut TirtayasaAbstract:Workload was predicted based on work pulse that was measured using 10 beats method on radial artery with stopwatch. The indication of subjective disorders was measured based on the farmers’ general fatigue and musculoskeletal disorders before and after work. General fatigue was measured using 30 Items Self Rating Questionnaire Industrial Fatigue Research Committee from Japan Association of Industrial Health, while musculoskeletal disorders were measured using NIOSH Nordic Body Map Subjective Filling.

Statistical analysis to find out the mean difference of the data before and after work was analyzed using t-Paired test with significance level of 5%. RULA result recommended changing from bending work posture using the old tool into standing work posture using new hole maker. The old work posture (P0) showed RULA grand score of 7 with high risk level, while the new work posture (P1) showed RULA grand score of 3 with low risk level. There was significant difference on subjective disorders of the farmers (p<0.05) on P0 and P1 on general fatigue and musculoskeletal disorders. The fatigue score of P0 was 51.27 while P1 was 40.82 which meant there was reduction of 20.4%. While the musculoskeletal disorders score of P0 was 70.75 and P1 was 50.58 which meant there was reduction of 28.5%. It can be concluded that the improvement of work posture using RULA analysis decreases work risk level and subjective disorders of strawberry farmers in Bali.

Jeffrey Forbes-Air Temperature and Relative Humidity Study: Torgac Cave, New Mexico. Journal of Cave and Karst Studies 60(1): 27-32. AIR TEMPERATURE AND RELATIVE HUMIDITY STUDY:
2015Co-Authors: Torgac Cave, New Mexico, Jeffrey ForbesAbstract:Torgac Cave, located in south-central New Mexico is remarkable for at least three reasons: its extraor-dinary gypsum speleothems, its large bat population, and the unusually cold temperatures within the cave. It has been proposed that the presence of the bats and the speleothems may be related to the anom-alous temperatures observed in the cave. This paper reports the results of a five week study of cave air temperature and relative humidity conducted during January-February 1995. Several different techniques were employed to measure the temperature and relative humidity (RH) of the cave atmosphere. A Sling Psychrometer was used to make spot measurements of temperature and RH at 11 locations throughout the cave on two successive dates. In addition, hourly measurements of air tem-perature and RH at a single location were recorded over a five week period using a capacitance probe and data logger. A novel technique for inferring RH was also attempted in which kaolinite clay samples were placed at different locations throughout the cave, and at different elevations above the cave floor at a single loca-tion, and allowed to equilibrate with the cave air. Subsequent laboratory analysis of the water activity and gravimetric water content of the clay samples following equilibration allowed the time-averaged RH to be inferred, and these data were used to reconstruct the vertical RH profile of the cave atmosphere
