Abstract

The accumulation of water on the ground is what causes flooding, whereas rainfall is the amount of rainwater collected in a flat area Rainfall and flooding are two related but distinct concepts. While rainfall refers to the amount of precipitation that falls in a particular area, flooding is the result of excessive water accumulation on the ground. Indonesia can be classified as a country with high rainfall due to its average annual rainfall ranging from 2000 to 3000 millimeters. In cases of heavy rainfall, excessive water discharge can occur. This can result in flooding when the land, rivers, or water reservoirs cannot manage the overflow effectively. Flooding is a common occurrence in Kotabaru Regency located in South Kalimantan, as it is a combination of mountainous regions, coastal areas, land areas, and small islands. The objective of the study is to examine whether flooding is always caused by high rainfall in Kotabaru Regency from January 2018 to December 2022. The correlation analysis is part of the research design, which utilizes secondary data collected and analyzed in Microsoft Excel. The findings suggest that moderate intensity rainfall is responsible for 73.3% of floods that occurred between 2018-2022. Moreover, 26.7% of floods occurred when rainfall is less than 20 mm/day. However, other factors such as monsoons, tropical cyclones, and El-Nino Southern Oscillation (ENSO) can affect the variability of rainfall and inffluence the occurrence of flood in the area.

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.
