The utilization of radiation in the field of nuclear medicine uses several main tools, one of them is the gamma camera. In its use, the gamma camera must always be in prime condition in accordance with the regulation of the Badan Pengawas Tenaga Nuklir (BAPETEN) No. 17 of 2012. To ensure that the gamma camera is always in prime condition, it is necessary to carry out several QCs (Quality Control) within a certain period of time with reference to international standards and recommendations from manufacturers. QC results show the measured value still within the required range (acceptance criteria), so it can be said that the gamma camera is in prime condition and ready to be used. The Nuclear Medicine Installation of RSUD A. W Sjahranie Samarinda use Cobalt-57 flood source plates to measure extrinsic uniformity during daily QC. This study used data in the form of tables of extrinsic calibration measurements and verification measurements as well as graphs of Cobalt-57 activity against QC time with extrinsic calibration methods and verification measurements were shown in this study. The conclusion is the lower the activity, the longer the QC times. Besides, the QC times based on the extrinsic callibration and verification measurements are not much different.

Diagnostic Reference Level (DRL) is a form of investigative level used as a tool to help optimize protection in radiation exposure for diagnostic and interventional procedures. In simple terms, DRL is the amount of dose that is set and becomes a reference in identifying the reception of high radiation doses received by patients for certain types of examinations. DRL aims to optimize the use of radiation in medicine and help avoid overexposure to radiation. The purpose of this study was to determine the local DRL value on the examination of the abdomen at the Radiology Installation of A.W. Sjahranie Hospital Samarinda. Data processing in this study was carried out with quantitative analysis techniques, namely descriptive statistics. This analysis technique used secondary data obtained from the results of recaptures or archival books for examination of the abdomen. Data processing was carried out with a measure of diversity through the calculation of the third quartile (Q3) in the data distribution. It was assumed that 75% of patients performed examinations with a common diagnosis. The results of these calculations are visualized in the form of a graph of the relationship of CTDIvol with the number of patients and a graph of the relationship of DLP with the number of patients. In the abdomen examination, a CTDIvol value of 12 mGy and a DLP value of 1545.5 mGy.cm. The conclusion obtained from this study is the DRL value at A.W. Sjahranie Hospital Samarinda is relatively low, but it still needs to be optimized by medical physicists.

Bench press is a form of powerlifting exercise that aims to increase the strength and endurance of the muscles of the upper body, that is, the muscles of the chest, arms, and shoulders. The characteristic of the bench press exercise is to lift or push the weight using both hands in a supine position. The purpose of this research is to determine the effective angle required for lifting weights with the least amount of thrust (biomechanics aspects). The research steps were carried out in four stages, namely: first, designing biomechanics mathematical equations; second, experiments on people doing bench press movements; third, processing biomechanics data; and fourth, analysis and discussion of biomechanics data. According to the study's findings, an effective angle was obtained by analyzing the thrust to lift the barbell, that is, the angle flanked by the upper and lower arms, which is approximately 89°-114° for those who use the smallest thrusts on the grip: 0.4 m, 0.5 m, and 0.6 m. It can be concluded that the wider the distance between the grips, the greater the thrust required.
