Penentuan Awal Waktu Salat Wajib di Kota Sengkang dengan Menggunakan Metode Klasik dan Kontemporer
No full textAbstractThe main problem in this research is how to determine the beginning of prayer times using classical methods and contemporary methods in Sengkang City. The subject matter is further divided into 1) How to determine the initial prayer time in Sengkang City using the classical method? 2) How to determine the beginning of prayer times in Sengkang City using contemporary methods? The purpose of this study is to obtain information related to how the people of Sengkang city determine the start of prayer time both classically and contemporary. The purpose of this research is to obtain information related to how the people of Sengkang city determine the start of prayer time both classically and contemporary. Researchers make observations, interviews and documentation in order to collect accurate and relevant data for research.This type of research is a qualitative field research in which the researcher collects data directly by going directly to the field to obtain more efficient data, while the data mining technique uses reference books related to research titles, journals, previous theses and observation methods of interviews and documentation. .The results obtained in this study are the first people in the city of Sengkang in determining the time of obligatory prayers using classical methods such as natural phenomena, shadows of objects, animal sounds and using methods compiled by angregurutta H. Muhammad Yunus Martan. Second, the majority of people in the city of Sengkang use the decree of the Ministry of Religion of Wajo Regency, thus indirectly the community uses the contemporary method used by the Ministry of Religion of the District. Wajo, namely using the formula for determining prayer times and using applications for determining prayer times, one of which is a pro Muslim.Implications The research in this thesis is a matter of determining the initial time of the obligatory prayers which the public must understand well. As for the suggestions and hopes from the author, namely, to everyone who covers the issue of worship, especially from the Ministry of Religion and astronomy students to carry out socialization and counseling related to determining the initial time of compulsory prayer.Kata Kunci: Salat, Klasik, Kontempore
Studies of dose distribution to Lung and Stomach and Estimation of Second Cancer Risk due to Outfield Dose in Radiotherapy with 60Co Teletherapy Beam
No full textA critical component of the radiation regimen for treating cancer patients is the precise dose delivery to the treatment organ while minimizing the dose to the healthy tissue. This study aims to evaluate in-field organ dose and dose distribution outside the target organs to estimate the excess lifetime risk of second cancer. The study was carried out with a male Alderson Rando Phantom. 20 sets of thermoluminescence dosimeters (MTS-100) were used in this study. The in-field organs absorbed dose was measured by inserting TLDs at different geometrical depths of the left lung, right lung, and stomach, and for peripheral organs skin dose TLDs were placed at the surface of the corresponding organs. Target organs were irradiated at 100 cGy and 200 cGy by a 60Co teletherapy unit, and irradiated TLDs were read out by a RE-2000 TLD reader. For precise dose delivery to the cancerous organs by 60Co teletherapy, the depth dose correction factor for lung cancer treatment is 0.8667 ± 0.01, and for the stomach is 0.7856 ± 0.017. In the case of the treatment for the lung and stomach, the closest organs received significant doses compared to the other distant organs. Thus, the risk of second cancer due to the peripheral dose is obtained. The stomach is at the highest risk when the lung is the target and the liver is at the highest risk when the stomach is the targeted organ
Hazard level of vehicle smoke by fuzzy multiple attribute decision making with simple additive weighting method
No full textClean air is a necessity for human. Human needs clean and healthy air without being contaminated by vehicle smoke that can endanger human health. vehicle smoke contains harmful substances for human including carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx) and lead metal (Pb). This can make air quality worse and can cause human be suffered of diseases including ARI (Acute Respiratory Infection), shortness of breath, sore eyes, coughing, brain damage and mental disability in children. Decision Support System (DSS) is a system to support Managerial decision makers in semi-structured decision situations and in this research author made a study of the DSS model to determine the level of danger of vehicle smoke, this study uses the Fuzzy Multiple Attribute Decision Making method (FMADM) where this method is a way to find optimal alternative from a number of alternatives with certain criteria, from very low things that was from 0-0.25, medium from 0.3-0.50, to the most dangerous thing that was from 0.8-1. Hopefully with the existence of this research later it can be useful for the community, especially for public health
