Bolus is a material that has properties similar to body tissues and is used to maximize the absorbed dose on the skin surface. The purpose of this research was to determine the most optimal treatment to kill fibrosarcoma on the patient’s skin surface by comparing the isodose curve and the value of the radiation absorption dose on the physical bolus (from CT-Scan) and model bolus (TPS). This study used data in the form of bolus images (with a bolus thickness of 0 cm, 0.5 cm and 1.0 cm) and phantom image. Then the data was processed with Treatment Planning System (TPS) and given energy variations in the form of electrons (10 MeV, 12 MeV, dan 15 MeV) and photons (6 MV and 10 MV). The result of this research was an isodosis curve that describes the distribution of the dose and the value of the absorbed dose of radiation received by the skin surface. The conclusion of this research is a bolus thickness of 0,5 cm and an electron energy of 15 MeV, has more even isodose curve (covering the entire tumor) and the maximum absorption dose value were 5720 cGy for physical bolus and 5710 cGy for TPS bolus.

Research of the relationship between electrical conductivity and the concentration of table salt solution in several brands of table salt, namely brand A, brand B and brand C, has been done. Electrical conductivity () is used as the dependent variable, while concentration (C) is used as the independent variable. The concentration values are 0.1%, 0.2%, …, 0.7% for each brand of table salt. Measurements of electrical conductivity using a tool Conductivity Metertype pH/EC-983. Next, the average of the result of the measurements of electrical conductivity (σ ̅) are plotted against the concentration (C) of the table salt solution for the each brand of table salt, where each of the result is a straight line (linear) that it has a positive gradient/slope, that is σ ̅=(1360000C+694)µS/cm for brand A table salt, σ ̅=(1315300C+644)µS/cm brand B table salt and σ ̅=(1281700C+566)µS/cmfor brand C table salt. It seems that the gradient/slope of the straight lines in the various brands of table salt is almost the same, which it means that in general the content of ions in the various brands of legal table salt is relatively not much different. While the positive value of the gradient have the meaning that the higher the concentration of table salt solution, the higher the value of the electrical conductivity, which it is theoretically compatible with the physical concept.

Abstract Noise is unwanted sound that can cause health problems and environmental comfort at a certain level and time. Noise Induced Hearing Loss (NHL) is a type of sensorineural hearing loss caused by exposure to sufficient/loud noise over a long period of time. This study was conducted to determine the effect of noise on the hearing of workers working in the Ground Handling area of Samarinda airport, to determine the noise level received by workers in the Airport Ground Handling Area, and to know the importance of using PPE on the hearing of workers while doing work. The noise measurement method is measuring at predetermined points using a Sound Level Meter. Then, it was continued by measuring the hearing level of workers in a soundproof room alternately using audiometry, then a correlation test was carried out to determine the relationship between the two variables, namely noise and the hearing level of workers. Based on the results of the study, it is known from the results of the average hearing that has been correlated with total noise exposure in the work area, it can be seen that the hearing level of workers is decreasing over time, this is due to the amount of noise exposure received by workers during work activities.

Knowing the condition of the waters is very important for the sustainability of aquatic ecosystems. The condition of the waters so as not to have a bad impact on aquatic ecosystems can be known through temperature and salinity parameters. Seawater temperature is the distribution of heat in the ocean caused by the movement of water and other factors. The salinity of seawater is the level of saltiness or the level of salt dissolved in seawater. Temperature can be measured using a thermometer and salinity is measured using a refractometer. However, using these tools requires time, effort, cost, and manual data retrieval processes. Therefore, this research aims to make a temperature and salinity measuring instrument and determine the relationship between Voltage and salinity in the seawater. This research used the method of measuring electrical conductivity (DHL) to determine a change in magnitude. The temperature and salinity design consisted of an Arduino Uno, a YL-38 Module, and copper as an electrode, and a DS18B20 Temperature Sensor. the result of this research shows that has been done, the average error presentation of salinity is 0.00732% and temperature is 0.044 %. Through this research, salinity and the temperature instrument produced using electrodes made of copper and DS18B20 which operate at a Voltage of 4,8 Volts. The obtained a linear graph between stress and salinity. The relationship between voltage and salinity is directly proportional, the higher the salinity of seawater, the greater the output voltage.
