Abstract

The activity of lifting weights has many risks that can lead to complaints and work accidents such as mistakes in lifting excessive loads, overly bent postures, and other complaints that result in uncomfortable working conditions. This research was conducted to determine the risk level of work posture using the REBA method and biomechanics in lifting weights with different lifting variables. The research were took documentation data, angle and distance measurements by using the Kinovea application, and the data analyzed by using the REBA Assessment Worksheet and biomechanical equations. Based on the results obtained, the activity of lifting burdens on workers from the aspect of the REBA method mostly has a high level of risk category and only 1 worker has a moderate level of risk category. Meanwhile, from the biomechanics aspect, most of them have a risk level in the careful category, 1 worker has a risk level in the safe category, and 1 worker who has lifted a load of 50 kg has a risk level in the dangerous category.

Abstract

Dose Calibrator is one of the dosimeters used to measure radionuclide activity before being given to patients. In order to function as a radiation dosimeter, the dose calibrator must have several good dosimeter properties such as precision and stability. To test the dose calibrator, a source used by the hospital is required. One isotope that is widely used in the field of nuclear medicine, namely Tc-99m. The research steps this time are: firstly the elution performed by radiopharmaceuticals, secondly measuring background activity (background), thirdly calling for Tc-99m sources, fourthly measuring Tc-99m activity, fifthly calculating Tc-99m activity for testing precision, and sixth evaluate the results. Based on the research results on the precision test, it was found that the measurement results for the Tc-99m source were obtained at 0.578%. It can be concluded that the Capintec CRC 25R dose calibrator has good characteristics and performance, so that the measurement results can be trusted.

Abstract

Scales are one of the vital measuring tools that have long been used by humans in everyday life. In determining the measurement quality of the scales, calibration is needed to determine the value of uncertainty. In this regard, a study was conducted to determine the uncertainty of non-automatic electronic scales calibrated using the E2 class standard, and to determine the quality of the instrument from the measurement results by looking at the uncertainty of the calibration results of non-automatic electronic scales. The calculation of the calibration of the electronic scales includes the magnitude of the measurement repeatability, correction of scale readings, the effect of loading not in the middle of the pan, and the effect of hysteresis from the scale by using the direct comparison method to the mass of the reference standard, namely by using the mass standard from class E2. From the calibration of the electronic scales that have been carried out, the results of the correction uncertainty value are 0.0002 g and the maximum uncertainty value is 0.00027 g, while the combined uncertainty is obtained a value of 0.00032 g, which means that the non-automatic Electronic Analytical Balance meets the uncertainty. determined by the standard used. In addition, the non-automatic Electronic Analytical Balance scale is included in good condition with hysteresis test indications of no more than one resolution.

Abstract

Samarinda is one of the cities in East Kalimantan, in Samarinda itself there are many office buildings that use AC coolers. One of the office buildings in Samarinda is the Quality Testing and Certification Center of East Kalimantan’s Building (UPTD. Balai Pengujian dan Sertifikasi Mutu Barang Provinsi Kalimantan Timur). Room temperature and humidity greatly affect the level of worker productivity, but not many people understand the existence of sick building syndrome (SBS). The purpose of this study was to determine the characteristics of employees regarding SBS complaints based on age and length of work and to find out the description of room temperature and humidity at UPTD BPSMB. The type of research used is non-probability sampling with a descriptive approach. The sample in this study were UPTD BPSMB Samarinda employees with a sample size of 20 people. The sampling technique was determined by purposive sampling method. The results of this study showed that the most commonly experienced symptoms were dry skin (50%), drowsiness (40%), dry lips and fatigue (20%), eye irritation, headaches, and difficulty concentrating (15%). From the results of the cross-tabulations that were carried out, it was found that there was no relationship between temperature and SBS, age and SBS, and duration of work with SBS, Still, there was a relationship between humidity and SBS. It is suggested to the UPTD BPSMB to monitor the room at least once a month to see the temperature and humidity conditions of the room so that employees can work comfortably and can increase employee productivity.

Abstract

In the hospital itself, especially in the MCU Poly Radiology Installation, it is a unit that performs services such as Medical Check Up, making health certificates, and carrying out routine checks at an institution. ECG examination is one of the services most frequently performed routinely by patients. Examinations carried out include medical check-ups, monitoring of long-term therapy, patient to assessment before surgery, individual screening for high-risk jobs, examinations before participating in sporting events, and overall examinations as a condition of employment. This study carried out the process of withdrawing information or object descriptions or identifying objects contained in images by compressing or reducing image data. By using EKG data from TK.IV Samarinda Hospital by carrying out processing stages such as converting analog data to digital, cropping, and applying filters to EKG images. After the filter is applied to the image, it is found that after 5 types of image processing (RGB Image, Grayscale Image, Binary Image, Thresholding Image, and Edge Detection Image) on the results of the ECG signal it can be concluded that the processed signal retains the features of the existing signal and information. . Of the five types of processing methods, the clearest result is conversion to Edge Detection imagery.
