The radioactive source used is Iridium-192 or Ir-192, with an initial activity of about 12 Ci. This study uses a well-type chamber ionization detector to verify the brachytherapy source against HDR Ir-192. The well-type chamber detector measures the radiation dose given to the patient during the brachytherapy procedure. This study uses detectors to measure radiation dose at several points around the source. The study was conducted by verifying the activity of the radiation source in Ir-192 brachytherapy using a voltage of 200 V and 400 V. It was regulated using an electrometer connected to a detector. The results show that the well-type chamber detector could accurately verify the source of brachytherapy. In addition, the measured activity values are in accordance with those permitted in standardization in brachytherapy, which is around 10 to 12 GBq. Therefore, well-type chamber ionization detectors can effectively verify brachytherapy sources. Thus, proper radiation source verification is paramount to ensure patient safety and treatment effectiveness","PeriodicalId":34112,"journal":{"name":"Jurnal Fisika Flux","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135134562","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}

Measurements from this study used the PASI Mod Gemini 2 Sn-1405 seismometer for ± 30 minutes at 25 measurement points. Geopsy software is used for microtremor data processing to obtain the H/V curve. The results obtained are dominant frequency values between 1.3 – 7.6 Hz, amplification factor values between 1.6 – 6.93, and seismic vulnerability index values 0,5 – 8. After getting the values of these parameters, a distribution map is made based on the values of each parameter, making distribution map using surfer software by merging the values of each parameter and the coordinates of the research location points.

In the literature review, the things that were done included: looking for the schedule of the dawn prayer in the city of Pontianak over one year, knowing the geographical position of the city of Pontianak, the apparent annual motion of the Sun, and the effect of the annual apparent motion of the Sun on the initial oscillation of the Subuh prayer time. Apart from that, another thing done in the literature review was to look for the influence of the earth-sun distance on the oscillations of the dawn prayer time. The results showed that there were similarities between the oscillations of the annual apparent motion of the Sun and the oscillations of the dawn prayer time in the city of Pontianak. However, there is a time difference with an average of 41 days between the oscillation of the Sun's annual apparent motion and the oscillation of the time of the Subuh prayer. The results of the Study also show that the distance from the Earth to the Sun (aphelion and perihelion) affects the initial oscillation of the dawn prayer time. When the Earth is at the aphelion point, the time for the Subuh prayer falls later than usual. Meanwhile, when the Earth is at perihelion, the time for the dawn prayer falls faster than usual.","PeriodicalId":34112,"journal":{"name":"Jurnal Fisika Flux","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136368329","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}

Briquettes are densified products in the form of cubic, prism, or cylindrical shapes. One of the biomass produced from abundant agricultural waste in Riau Province is coconut coir. This is because Riau Province is one of the largest coconut-producing regions in Indonesia. The utilization of coconut coir waste is currently still limited to crafts, fuel, and planting media. This study aims to produce briquettes from a waste of old coconut coir and young coconut coir with the stages of the research process including cleaning, drying, grinding, adding adhesive, and densification. The resulting briquettes were then subjected to laboratory tests to determine the physical characteristics of the briquettes based on SNI No. 1/6235/2000 and structural characteristics using SEM and TG/DTG. The results showed that laboratory tests for old coconut coir briquettes and young coconut coir based on water content were 28.11% and 29.72%; based on ash content are 1.59% and 2.21%; based on the carbon content are 25.10% and 24.94%, and the heating value is 3019.54 cal/g and 3137.03 cal/g. For SEM analysis, the surface morphology of the briquettes looked smooth and there was no fragmentation indicating that the biomass was perfectly bonded with the binder used. Meanwhile, in the TG/DTG analysis, the results showed that there had been a mass decrease of around 90% for old coconut coir briquettes and 78% for young coconut coir briquettes at a temperature of around 450oC","PeriodicalId":34112,"journal":{"name":"Jurnal Fisika Flux","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135155758","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}
