Abstract

The Mahakam River is a source of water for the people of Samarinda, East Kalimantan. However, Mahakam river water is not classified as quality water. As a result of industrial mining activities, river water is polluted by heavy metals such as Lead (Pb). These problems can be overcome by using the adsorption method to purify water. The adsorption method has become popular in adsorbing heavy metals contained in polluted water. The purpose of this study was to synthesize natural materials which are adsorbents for the heavy metal Pb. The materials used as natural adsorbents are household waste, namely ashes (AG), egg shells (CT), tea dregs (AT). Based on the results of the Atomic Absorption Spectroscopy (AAS) characterization test, data were obtained on the decrease in the concentration of heavy metal Pb in samples of Mahakam river water. The initial concentration of 1.8 mg/L became 0.24 mg/L (10 gr adsorbent AG) and became 0.17 mg/L (10 gr adsorbent AG+CT). While the use of AT adsorbent was applied to artificial waste with an initial concentration of 40 mg/L to 0.002 mg/L. Furthermore, according to data measurement, modeling was carried out using the Langmuir Isotherm and Freundlich Isotherm models to determine the adsorption capacity of tea dregs, eggshells, and ashes.

Abstract

Thermoluminescent Dosimeter (TLD) is a personal dosimeter to measure radiation exposure which can capture and store radiation energies. It hits them and emits them in the form of light when heated. TLD aims to measure radiation exposure received by radiation workers. The purpose of this study was to determine the effective dose value of lung tissue at the Radiology, Radiotherapy, and Nuclear Medicine Installations in 2018 until 2021 at A.W. Sjahranie Samarinda Hospital. Data processing in this study was carried out using quantitative analysis techniques, i.e., descriptive statistics. This analysis technique used secondary data obtained from the results of recapitulation of absorbed dose values in Radiology, Radiotherapy, and Nuclear Medicine Installations. Data processing was performed by multiplying the equivalent dose values by the lung tissue weight factor. The results of these calculations are visualized in the form of graphs based on the effective lung doses for years and types of installation. Based on this study, in general, the highest to lowest effective dose values for lung tissue are from the Radiotherapy, the Nuclear Medicine, and the Radiology Installations. It matches theoretically in various references.
