Radiographers work in standing position, bending posture, lifting the patient, set object well on film. Radiographers work postures often creates a musculoskeletal disorders at arms, back and legs. Besides poor design tools, the physical environment can add to the workload. For analytic observational study was carried out on the workload, musculoskeletals disorder, and subjective fatigue at Sanglah Hospital radiographers, involving 10 samples for 6 days. Method: Measurements were performed before and after work. Workload conditions obtained by measuring the heart rate, muskuloskeltaldisorders taken from nordic body map questionnaire, subjective fatigue through the 30 item questionnaire. Results and discussion: there are increase of 29.18% (P=0,00) workload, musculoskeletal disorders 33.9%(P=0,00), subjective fatigue at 16,5%(P=0,00). Then needed the intervention of ergonomics to improve working conditions in the radiology department. KEYWORDS: Radiographer ; Workload ; musculoskeletal ; disorders ; fatigue. INTRODUCTION There are several names, type of work, and the responsibility of radiation workers in the health sector, one of which is a radiographer who has the task of making medical images, patient's organs to enforce the diagnosis of a disease using ionizing electromagnetic radiation. The use of ionizing radiation of X-rays have very short wavelengths ranging 10 -10 meters, shorter than the wavelength of visible light. With such a short wavelength, X- rays can ionize the material in its path. This will create a risk of biological effects. This radiation field work environment can increase the workload radiographer in addition to the microclimates.In doing the work, radiographers working in a standing position, bending working attitude will cause health problems for the radiologist. This work attitude is not a natural working posture. Working attitude can naturally not as a cause of various disorders of the musculoskeletal system muscles (Manuaba, 1998). Working position standing working attitude unnaturally bent, causing disruption in Sytem musculoskeletal and occurs under considerable pressure in the disccus intervertebratalis that can cause low back pain, long-term working attitude will cause the body becomes bent (Pheasant, 1991; Kroemer and Grandjean, 2000). Radiographers at Sanglah Public Hospital specially at Emergency Care Unit have 3 shift of working time. Morning shift held for 7 hours, start from 07.00 a.m until 02.00 p.m Afternoon shift held for 6 hours, start from 02.00 p. m until 08.00 p.m. and night shift held for 11 hours start from 08.00 p.m until 07.00 a.m. From the description it would require an observational study the extent of the workload arising from the work radiographers in Denpasar Sanglah Hospital. The results of this study can be used as a reference for intervention to improve working attitude, work stations, and tools Radiographers work in order to improve productivity of the radiographer. MATERIAL AND METHOD This research was conducted analytical observational to 10 sampel radiographers of Sanglah Public Hospital. Active Radiographers on the work of radiological procedur and technique who met the inclusion criteria and were simply chosen randomly. Radiographers workload was predicted based on work pulse that was measured using 10 beats method on radial artery with a stopwatch before and after work. The indication of subjective disorders was measured based on the radiographers general fatigue and muskuloskeletal disorders before and after work. General fatigue was measured using 30 Items Self-Rating Questionaire Industrial Fatigue Research Committee from Japan Association of Industrial Health, while musculoskeletal disorders were measured using NIOSH Nordic Body Map Subjective Filling. Enviroment temperature and humidity was measured using sling Psychrometer. The noise was measured using Sound Level Meter. The data of measurement results were
