In this study, Tungsten material with a thickness of 10 cm was used as a shield for photon with energies of 2 MeV, 3.3 MeV, and 5 MeV. This material shielding was simulated with Monte Carlo based software, Particle and Heavy Ion Transport System (PHITS). The dimensions of the shield material are 40×40×10 cm3 which are placed at various distances from the source:20 cm, 50 cm, and 100 cm. The results obtained show that these photons with energies of 2, 3.3, and 5 MeV can be attenuated by the shield at all defined source distances. The flux of particles passing through the shield decreases with increasing distance. Therefore, Tungsten material can be a candidate for photon shielding in the medical physics field.","PeriodicalId":314761,"journal":{"name":"Jurnal Teori dan Aplikasi Fisika","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133627125","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}

The artificial zeolite products were characterized using XRF, XRD, UV-Vis spectrophotometric and ICP-EOS. The results showed that the composition of the artificial zeolite was aluminum, silica, phosphorus, potassium, calcium, titanium, vanadium, chromium, manganum and ferum. The crystal structure of the optimum sample from the UV-Vis spectrophotometric characterization obtained the crystal structure of a natural zeolite type, namely Chabazite.

The macrocyclic type is known for its enhanced stability, resulting in minimal release of Gd ions within the body. The distribution of macrocyclic Gd within the kupffer cells in the liver, undergoes a diffusion process. In this study aimed to investigate the diffusion mechanism of macrocyclic gadolinium in kupffer cells. It employs a simulation geometry model employing Monte Carlo Cell and a three-compartment experimental model. The kupffer cell model in the simulation was generated using Blender 2.93 application, consisting of three compartments, while the experimental model involved three compartments containing a NaCl solution. The simulation results revealed that kupffer cell membran densities of 1480 molekul/μm2, 2961 molekul/μm2, 4442 molekul/μm2, and 5922 molekul/μm2 exhibited respective half-lifes of 0.547 s, 0.261 s, 0.198 s, and 0.148 s. Furthermore, the experimental results indicated that the models with 100, 200, 300, and 400 holes displayed half-lives of 1720 s, 578 s, 530 s, and 240 s, respectively.

In Indonesia, the proportion of disability adjusted life-years (DALYs) contribution from stroke is around 9.7% and is the number one cause of disability. People with disabilities will have difficulty doing daily activities, especially communication. Therefore it is necessary to develop communication aids that can help stroke sufferers communicate daily by utilizing palm movements. In this study, two flex sensors were placed on the fingers. Communication aids for stroke sufferers function to detect four basic movements, namely: \"I want to eat\", \"I want to drink\", \"I want to urinate/poop\",and “rest”. The four sentences are also displayed on a display and also on the Smartphone. The detection of these four movements is obtained by bending the two fingers which are detected using a flex sensor placed on a glove.

The battery in this study is a battery or accumulator. The sample image is obtained using a thermal camera to determine the characteristics of the battery based on color. The basis for identifying characteristics is obtained by separating the RGB color components in the thermal image. Each color component will calculate the average pixel intensity value and see the difference in the resulting value. The results showed that the distinguishing characteristic between the sampling conditions was that the green pixel intensity mean value when the battery was being charged was higher than the condition of the battery before being charged and the condition of the battery when it was loaded. The average value when the battery is on the power side is 107 pixels green, while the average value when the battery is before charging is 81 pixels green and when the battery is loaded the average green value is 82 pixels.","PeriodicalId":314761,"journal":{"name":"Jurnal Teori dan Aplikasi Fisika","volume":"268 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123410544","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}

Unfortunately, this knowledge is not yet widely known among the general public. Therefore, providing information on daily CO2 levels can serve as a means to educate and raise awareness about the dangers associated with CO2 levels. To simplify access to CO2 concentration information, a prototype of a CO2 concentration measurement device based on the NodeMCU ESP8266 microcontroller, which can be connected to Wi-Fi, has been developed. To ensure data accuracy, the CO2 measurement device was calibrated using the NodeMCU ESP8266 microcontroller and data from an outdoor CO2 monitoring instrument at the BRIN (BPAA Pontianak) office, with an error value of 4.08%. The collected data from this device can be accessed through the Blynk application or a Google Sheets link.
