Abstract

Performance evaluation of diagnostic radiology modalities strongly supports the quality of radiation and images for diagnosis. This test requires certain materials as a substitute for human objects to avoid excessive radiation. Phantom as one of the object replacement media has been directed according to the characteristics of the tissue. This study aims to obtain the radiation response of artificial bone tissue made from eggshells with the addition of rice bran, resin and catalyst, in 4 (four) mixture compositions. Test variations were carried out by changing the X-ray tube voltage (80 kV, 100 kV, 120 kV and 140 kV) to obtain CT-Scan images and analyzed using Radiant DICOM software. The results showed that the Hounsfield unit (HU) value of the artificial bone phantom corresponded to the HU value range of real bone organs, which is between 100 and 700 HU. This value affects the analysis of the resulting image resolution in the form of SNR and CNR values, in the range of (8.07-37.38) and (14.98-28.20), respectively. Conclusion Artificial bone tissue phantom made from eggshells and rice bran has the potential as a testing medium because it corresponds to the characteristics of human bones, especially in adulthood, and has the potential as a testing medium.

Abstract

Geothermal energy presents a promising alternative for electrical power in Indonesia, especially in regions like Papua, where current power plants heavily rely on fossil fuels. As Papua anticipates an increase in energy demand due to regional expansion, exploring renewable energy sources becomes crucial. Mosso Village in the Muara Tami District of Jayapura City is known for its geothermal potential, evidenced by the presence of hot springs in the area. To assess this potential, a geophysical study was conducted focusing on the geothermal system in Mosso Village. This study utilized 3D modeling of subsurface structures through the gravity method. It incorporated both primary and secondary data, with secondary sources including GGMplus gravity model data, digital elevation model (DEM) data, and geological maps. Primary data comprised rock density samples representing surface densities of geological units in the study area. The GGMplus gravity data was central to the analysis, which involved processing, correcting, and modeling these data to identify geothermal features. The 3D modeling revealed a high-density zone at a depth of 1200 m beneath the hot spring source, interpreted as an indication of hot rock or magma intrusion, suggesting it as the geothermal heat source. Additionally, the model identified a low-density area around the hot spring, interpreted as a sedimentary groundwater basin in the geothermal system of Mosso Village. This study highlights the potential for utilizing geothermal energy in the region and provides valuable insights into the geothermal system’s structure.

Abstract

An effective way to address the plastic waste problem is by minimizing the use of non-biodegradable plastics. One approach is to develop biodegradable plastic packaging that is environmentally friendly. This research used Goroho banana peel starch, this type of banana is used because it has good potential with a starch content of 80.89%. In this research, variations in ZnO concentration of 1%, 2%, 3%, 4%, and 5% w/w were conducted. This research aims to determine the characteristics of physical properties of bioplastics with the addition of ZnO. This research uses a laboratory experimental method through several processes, namely goroho banana peel starch extraction and bioplastic manufacturing. The results indicated that varying concentrations of ZnO significantly influenced the physical and biodegradation properties of the bioplastic products. The physical properties of the bioplastics produced have met the Indonesian National Standard (SNI) for water uptake of 21.5% and biodegradation of 60 days. FTIR results show that the functional groups of bioplastics are identical to the constituent functional groups, namely starch, so that their properties resemble the properties of their constituents, which are easily degraded. The most optimum bioplastic is BPZ 2 with the addition of ZnO at 2% w/w, which produces water uptake of 1.859% and degradation time of 12 days.
