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

Light intensity is the intensity of light emitted as a light source in a certain direction. In a building, human safety depends on the level of lighting, and helps create a creative visual environment. Broadly speaking, light sources are divided into two, namely natural light and artificial light. According to the Indonesian National Standard (SNI), the recommended minimum lighting strength for lecture halls is 250 lux. Therefore, this study aims to determine whether the lighting intensity of the lecture hall in the SLC building meets the SNI standard, and to determine the relationship between natural and artificial fluxes in the SLC lecture hall of the Faculty of Mathematics and Natural Sciences, Mulawarman University. This study uses the method of measuring the intensity of illumination with a luxmeter measuring instrument at predetermined measurement points. The results obtained in this study, namely, the intensity of natural and artificial lighting in the lecture hall of the SLC building did not entirely meet the SNI standard, because in use without lights and 6 lights the point is far from the light source. The relationship between natural and artificial lighting flux corresponds to changes in the intensity of natural and artificial lighting with time, the greater the change in lighting intensity with time, the greater the lighting flux in the lecture room with time.

Abstract

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.

Abstract

This study was done to develop a Yagi antenna for a 1.8 GHz mobile phone using ironwood as a signal booster as an alternative for some local communities. Designing a Yagi antenna for this study's initial phase, which took place at FMIPA Mulawarman University's Electronics and Instrumentation Laboratory, involved considering its size and range. The boom length is 1 m, the driven length is 7.9 cm, the reflector length is 8.4 cm, and the director length is 7.5 cm after calculating the length and distance of the Yagi antenna parts. The distances between the elements are as follows: 4.1 cm separates the reflector from the driven, 2.5 cm separates the driven from director 1, 3.3 cm separates director 1 from director 2, and 4.1 cm separates directors 3 through 9 from each other. The download signal (receiver) and upload signal were the characteristics used in data collection on Batu Besaung, Samarinda, and East Kalimantan (transceiver). During the course of this data collection, ten maximum data collection points were taken in each of the compass' eight directions. In the final step, data processing is done to find out how much gain the designed Yagi antenna produces. The highest rates recorded are 2,27 Mbps download (receiver) and 2,59 Mbps upload (transceiver), both measured at noon at the tenth point and in the south.
