In its use, the gamma camera must always be in prime condition in accordance with the regulation of the Badan Pengawas Tenaga Nuklir (BAPETEN) No. 17 of 2012. To ensure that the gamma camera is always in prime condition, it is necessary to carry out several QCs (Quality Control) within a certain period of time with reference to international standards and recommendations from manufacturers. QC results show the measured value still within the required range (acceptance criteria), so it can be said that the gamma camera is in prime condition and ready to be used. The Nuclear Medicine Installation of RSUD A. W Sjahranie Samarinda use Cobalt-57 flood source plates to measure extrinsic uniformity during daily QC. This study used data in the form of tables of extrinsic calibration measurements and verification measurements as well as graphs of Cobalt-57 activity against QC time with extrinsic calibration methods and verification measurements were shown in this study. The conclusion is the lower the activity, the longer the QC times. Besides, the QC times based on the extrinsic callibration and verification measurements are not much different.","PeriodicalId":221598,"journal":{"name":"Progressive Physics Journal","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134206252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interpretation of SP data can be used for various purposes such as the detection of landslide-prone areas, exploration of various types of minerals, and identification of the parameters of a fault or crack. In this study, SP data acquisition was carried out in Tambakrejo Village, Pacitan District with a total of 102 measurement data which aims to determine the depth and dip of the Grindulu Fault. SP data acquired in the field needs to be corrected for reference, namely corrections caused by a displacement of the starting point of measurement. This data is then filtered to increase the signal-to-noise ratio (SNR) and sharpen the resulting anomalies. This filtering process is carried out using the ICEEMD (Improved Complete Ensemble Empirical Mode Decomposition) method which is a development of the EMD method. Furthermore, the SP data inversion process to obtain model parameters is carried out by utilizing the CSA (Crow Search Algorithm) method. Based on the anomaly model generated from the SP data inversion process, it can be concluded that the Grindulu Fault was identified at a distance of 803,8 meters from the starting point of measurement with depths ranging from 11,06 to 102,74 meters. Furthermore, based on distance, depth, and anomaly shape data, the dip value can be calculated. The calculation results show that the dip of the Grindulu Fault in the study area is 75.58o. Identification of the Grindulu Fault in the form of depth and dip is very important in efforts to model the fault comprehensively.","PeriodicalId":221598,"journal":{"name":"Progressive Physics Journal","volume":"25 34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116196400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A bonang is a musical instrument with a small, hollow structure. This study was conducted to determine the relationship between the surface area of the bonang pot and the frequency of the basic tone generated, and to find out the results of the variety of sounds on the bonang musical instrument. A bong that was stopped only after the sound was muted was applied to record the audio directly. Using AudioCyti software, a surface area and frequency are then measured, and the output signal is measured using the Fourier transform method. The parameters measured are surface area and frequency. In accordance with the results of this study, there is a connection between surface area, or the basic frequency, which is achieved with a frequency of 0.88363, and frequency, which is obtained with a frequency of 0.986053. So, it is concluded from the study that has been carried out that the surface area has an influence on the frequency. Users can determine the frequency of a bonang musical instrument's fundamental tone by varying its frequency values from lowest to highest and analyzing the output signal with audiocyti software. As a result, each sound produced by a bonang pot is distinct and nonsequential. This is because, like modern musical instruments, a bonang laras slendro does not yet have a set tone frequency.","PeriodicalId":221598,"journal":{"name":"Progressive Physics Journal","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114538028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This effect is indicated by the presence of a functional relationship between the heating test and the value of the four physical quantities. The relationship between heating repetition and viscosity is a quadratic function, the relationship between heating repetition and mass density is a linear function, the relationship between heating repetition and surface tension is a quadratic function, and the relationship between heating repetition and Newton cooling constant is a quartic function.
