Abstract

This research aims to determine the effect of exposure to radiation dose on the distance from the radiation source, determine radiation dose exposure with variations in exposure factors (voltage), and to determine the radiation exposure received by workers / operators in the CT-Scan room at Bhayangkara Hospital Makassar and using a sensitive Surveymeter with variations in the exposure factor (voltage) of 100 kV, 120 kV, and 135 kV and a variation of the distance from the radiation source of 0 m, 1 m, 2 m. The results showed that the highest dose was on the front side with a voltage of 135 kV at a distance of 0 m, namely 1.5 nSv / h. While the lowest dose is on the left side with a voltage of 100 kV at a distance of 2 m, namely 0.6 nSv / h. Radiation exposure received by workers / operators in the CT-Scan room at Bhayangkara Hospital Makassar at a voltage of 135 kV, a distance of 1 m from the radiation source, namely 1.5 nSv / h. This is in accordance with the provisions of BAPATEN, namely the value of the dose received does not exceed 50 mSv in (one) year.

Abstract

Purpose of this research to determine the effect of mass of source on thickness of thin film, with using the vacuum thermal evaporation. The metal used is Ag with a purity of 99,99% as a source of evaporated metal and using glass preparations as a substrate on which metal is deposited. By using three types of characterization such as FPP, SEM and EDS, the research results were obtained accurately. Based on  these characterizations, the results obtained a significant relationship between mass of source and thickness of thin film, increasing the mass of the source will increase the thickness of thin film. This result can be used as a reference in producing thin films with specific of thickness.

Abstract

This study aims to determine the effect of high voltage usage and standards on the quality of radiographic imagery produced on X-ray aircraft. Data retrieval was obtained by conducting testing in the Radiology Installation room of the Makassar Public Lung Health Center by using an X-ray aircraft of thosiba brand type with drx-1824B model unit. The result obtained is the voltage of the tube gives an influence on the quality of radiography imagery where for the use of standard tube voltage provides good radiographic imagery quality results with a graph reading histogram voltage of 50 kV with a distance of 100 cm and a time of 10 mAs with a black background image starting at the position of 16 to 36 and the position of the object is 37 to 79 which is then able to provide information because the edges of the object and background can still be distinguished clearly and for the high voltage used the result is less tub because it can reduce the contrast value of objects and background is indistinguishable, this is seen in the histogram readings voltage of 90 kV and distance of 100 cm and the time of 10 mAs has a gradation of gray color that dominates compared to the black background whose position starts from 10 to 132 which can not provide information on the edge value between the background and the object phantom water because both seem to be fused so that it is indistinguishable and causes an inadequate image contrast Not good enough.

Abstract

This study aimed to identify the usage method of high voltage tube (kV) with doses and velocity of exposure radiation received by patients during the head checkup and to know the point or safe distance from the radiation sources to the patient and the employee of radiation in the radiology room in Bhayangkara  Hospital Makassar . Measuring Entrasce Skin Exposure using multimeter X-Ray Barracuda, and measuring the velocity of exposure radiation using surveymeter at a distance of 1 m, 2 m, and 3 m from the object .The eksposi factor used at voltage tube 70 kV, 80 kV, 90 kV, 100 kV, 110 kV, and the current of tube 200 mA, 160 mA, 100 mA, 50 mA, 20 mA, and time ekspos used 0,250 s. From this research obtained that using of high voltage tube 110 kV produce low Entrasce Skin Exposure 0,590 mGy and using standard voltage tube (kV) 70 kV produce high Entrasce Skin Exposure 4,188 mGy . And measuring the velocity of exposure radiation produce 2500 µSv/h at a distance  1 m, 2200 µSv/h at a distance 2 m, and 1700 µSv/h  at a distance 3 m, with high voltage tube at 110 kV. And using voltage tube 70 kV produce low velocity of exposure radiation of 115 µSv/h at a distance 1 m, 72 µSv/h at a distance 2 m, and 7 µSv/h at a distance 3 m. Results showing that the more high voltage tube the more few Entrasce Skin Exposure received to the patients but bigger the velocity of exposure radiation for the employee of radiation and the community and the close distances from sources, higher the rate of exposure radiation, and vice versa . For that reason , point / safe distance for the employee of radiation room and the public should be at a distance 5 m from the radiation sources.Keywords : radiation, Entrasce Skin Exposure , velocity of exposure radiation, high voltage

Abstract

This research aimed to identify the location of accumulation and distribution direction of the spread of leachate at landfills Tamangapa around Makassar Multichannel Resistivity meter resistivity measurements using the form of the voltage injected into the subsurface through a predetermined trajectory as much as six trajectory. The method used is Geolistrik resistivity method with Wenner-Schlumberger configuration. Data processing is done by using RES2DINV to generate a 2D cross-section of data below the surface, and use Voxler 3 to determine distribution direction and location of the accumulation of leachate seepage of leachate . Based on the location of the results obtained by the accumulation of leachate generated from landfill waste decomposition Tamangapa Makassar interpreted to be at a depth of 2.50-18.52 m with apparent resistivity values from 0.0090-5.00 Ωm at coordinates 5017'727''LS and 119049'084''BT elevation 16-20 m above sea level. While the distribution of leachate seepage direction around Tamangapa Makassar interpretation in sector 1 seepage eastward direction which is at coordinates 5017'594''LS and 119049'202''BT with a depth of 2.50-12.80 m. In the second sector is interpreted towards see page of leachate to the west which is at coordinates 5017'727''LS and 119049'084''BT with a depth of 2.50-31.87 m.

Abstract

This research aims to design and compare the results to the biogas reactor with a stirrer with a biogas reactor without a stirrer. The research has successfully designed a biogas reactor with a stirrer with a stirrer using a dynamo as a player with a capacity of 11 kg. From the results of tests performed 3 times a day for 9 days, had the highest pH value data obtained on day 5 is 7.5 to biogas reactor with a stirrer and a biogas reactor without a stirrer. For the measurement of temperature changes irregularly due to unfavorable weather conditions remain. For the production of biogas in the biogas reactor with a stirrer, began to be seen on day 5 with a value of 76.3 cmHg whereas the increase in biogas reactors without biogas agitator begins to form on day 7 with a 76.5 rise in value. This tool is used for testing samples of cow dung as a sample of the most nice and easy to obtain. Based on the results of research conducted, it can prove that the biogas reactor stirrer dngan able to produce biogas more quickly than the biogas reactor without a stirrer this was due to the substrate in the fermentation container tercempur homogeneously so that the bacteria is able to reproduce a whole.

Abstract

This study aims to determine the physical quality of food containers made of dried banana leaves, teak leaves, and corn husks. The process of making a food container is carried out using a stainless steel mold which is then heated using a cooking thermometer to reach a temperature of 1000C and using a 10 kg load as a pressure, then printed for 5 minutes which is done 4 times printing for each food container. There are two tests for food containers, namely, the water absorption test, the average value of water absorption for food containers for dried banana leaves is 0.00%, 99,97% teak leaves, and 49.96% corn husks. The second test is test the resistance of the container based on temperature parameters. The temperatures used are 400C, 600C, and 800C, the three containers have different results, the dried banana leaf container can be used for hot food because it doesn't change after testing, while the food container made of leaves Teak and corn husk underwent changes during testing. Where teak leaves cannot be used for food with soup and corn husks cannot be used as food containers with food temperatures above 600 C.
