This type of therapy uses a source with low energy and penetration rate so that the organs around the prostate do not receive much of the absorbed dose. This study uses a calculation method Monte Carlo N-Particle 6 (MCNP-6) to calculate the interaction of photons with organ materials. The main objective of this research is to determine the number of seeds and the ideal source activity to achieve the optimal absorbed dose in the prostate and provide the minimum absorbed dose in the surrounding organs. Organs around the prostate include the testes, small intestine, descending colon wall, descending colon, sigmoid colon wall, bladder wall, and bladder. This study uses two types of radioisotope sources namely 103Pd and 131Cs which each has a photon energy of 21 keV and 30 keV. Variations made is the addition of the number of seeds from 60 to 100 at intervals of 8 seeds symmetrically away from the center of the prostate and variation of source activity from 0.1 mCi to 0.6 mCi at intervals of 0.1 mCi for each type of source. Results of this study obtained the relationship that the more the number of seeds the greater the dose received by the prostate and surrounding organs, as well as the addition of source activity. The effect of increasing the number of seeds can increase the absorbed dose more significantly than the effect of adding activity to the organs around the prostate. Optimal absorbed dose for 103Pd is 125 Gy and 115 Gy for 131Cs. Based on the simulation results with MCNP-6, it is obtained that the ideal combination for the optimal absorbed dose is obtained from the source 103Pd is the number of seed 60 with 0.3 mCi activity, and source 131Cs is the number of seed 76 with an activity of 0.5 mCi. Source 103Pd provides a lower absorbed dose to the organs around the prostate compared to the source 131Cs.","PeriodicalId":512976,"journal":{"name":"Engineering Headway","volume":"58 S276","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140694709","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}

Parikesit","doi":"10.4028/p-k5delo","DOIUrl":"https://doi.org/10.4028/p-k5delo","url":null,"abstract":"The consumption of coffee has its health benefits and its risks, one of the risks is mostly related to cardiovascular diseases. One of the diseases is hypertension which is considered “the silent killer” as it is a serious condition which promotes other complications and typically has no symptoms for a period of time until it has done significant damage. Acute hypertension can lead to a stroke. It is a very serious medical condition where the blood flow to the brain is poor, causing the death of cells within the brain. Some medications, surgeries and other healthcare programs are capable of controlling stroke, but stroke still remains to be the main cause of death and disability in Indonesia. However, provided that the consumption is restrained, multiple studies show that coffee consumption actually can reduce the risk of getting a stroke, by consuming between 2 to 4 cups of coffee per day. Additionally, coffee can reduce the likelihood of blood clots from forming and is likely to alter the blood vessel physiology. Therefore, the current project will explore the possibility of utilization of bioactive compounds other than caffeine from coffee beans that can be implemented in a form of supplements to help in treating patients both with stroke symptoms and during the recovery phase. Protein docking analysis is an alternative way to search and predict for drug discovery. Through protein docking analysis we can gain information on the bioactive compounds and their respective interactions with the target. Based on the virtual screening pipeline, it is predicted that Dehydrokahweol could elicit possible lead for the anti-stroke activity.","PeriodicalId":512976,"journal":{"name":"Engineering Headway","volume":"317 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140698115","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 research consisted of 3 stages, namely making kepok banana peel starch, making edible films, and characterizing kepok banana peel starch and edible films. The yield of kepok banana peel starch obtained was 11.94%. Edible film production was carried out with variations in the glycerol-sorbitol concentration ratio of 100:0, 75:25, 50:50, 25:75 and 0:100 on a basis of 40% (w/w) of total starch weight. Functional group analysis of kepok banana peel starch and edible film was carried out with Fourier Transform Infrared (FTIR). Testing the characteristics of the edible film includes thickness, tensile strength, elongation, and Young's modulus. The results showed that edible film was successfully made with mechanical properties that tended to comply with the Japanese Industrial Standard (JIS) 1975 on the parameters of thickness, tensile strength, and young's modulus.","PeriodicalId":512976,"journal":{"name":"Engineering Headway","volume":"348 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140698340","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 purpose of this research is to determine the job sequence and calculating the total production time (makespan), and identify the sequence that create smallest makespan. The methods used in this research are Campbell, Dudek, & Smith (CDS) method, Palmer method, and Dannenbring method. The calculation results shows that the company's actual scheduling produces a makespan of 30,725.08 minutes. The result of CDS method produces the makespan of 30,634.18 minutes. Palmer's method produces the makespan of 30,743.75 minutes, and the Dannenbring method also yield the makespan of 30,743.75 minutes.
