The goal was to provide information on the use of DNA templates in chicken samples so that the molecular research sampling process may employ feathers instead of hurting the test animals. The sample used consisted of 10 Bangkok chickens which were sampled for young feathers and old feathers and the tips of the feathers. Method: Quantitative techniques by comparing the results of DNA isolation which were analyzed using a nano photometer and then confirmed using real-time PCR with the SYBR green method. Result: The analysis of purity and concentration showed that at the base of young chicken feathers, the average value of purity was at 1,790, with an average value of the concentration of 4,210. At the base of the old feather, the average value of purity was 0.638, with an average concentration value that was not detected. Likewise, at the tip of the feather, the average purity value is 0.894 and the concentration value is not detected. Confirmation tests performed on all samples using the real-time PCR melt curve method showed that all samples were detected with a Tm value of 78.5 for young feathers, 78.5 for old feathers, 79.0 for positive controls and 78.7 for positive controls, while negative controls were not detected. Conclusion: DNA isolation can be carried out at the base of the young feathers, the base of the old feathers and the tips of the feathers.","PeriodicalId":33216,"journal":{"name":"Bioeduscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46259704","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 disease is characterized by widespread discoloration with irregular and protruding edges. In treating cancer itself, radiotherapy technology, has been found. It is a method of treating cancer using high-energy radiation rays that are focused on cancerous tissue to kill or stop cancer cell division. This study aims to determine the effectiveness of radiotherapy technology as a treatment solution for melanoma skin cancer. The focuses of the study in this paper are the integumentary system and skin structure, melanoma skin cancer, the body's mechanisms for melanoma skin cancer, and radiotherapy as a treatment method. Methods: The research method used is literature study from various sources, to help understand the problem more deeply and completely. Conclusions: Melanoma, which attacks one of the body's integumentary systems, namely the skin, has a close relationship with homeostatic dysregulation and endocrine damage. However, radiotherapy method can be used to cure melanoma skin cancer by shooting X-rays and damaging the cancer cells and also reducing their spread to other parts of the organs. This method is effective because melanoma skin cancer is localized or has not spread to other organs. However, the use of radiotherapy can also have a negative impact on the body and can give unwanted side effects, so consideration is needed before using this method.","PeriodicalId":33216,"journal":{"name":"Bioeduscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49368459","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}

High-order thinking skills are a requirement for learning achievement in the twenty-first century. The goal of this project is to put quantitative evaluation instruments created by Jakarta elementary school teachers to the test. Methods: A mix method is used, which combines descriptive qualitative research with document analysis and quantitative research with instrument testing on reproductive system material, which is then examined using Anates. The participants in this study were eight Jakarta-based grade VI primary school teachers. Results: It demonstrates that teachers' capacity to construct evaluation instruments varies widely. Testing using Anates shows 15% of the questions compiled are valid and 85% invalid, 1 school with strong reliability and 7 other schools are less reliable. The difference shows that 42.5% are accepted and 57.5% are rejected. The level of difficulty showed that as many as 8.75% of the questions were in the very easy category, 18.75% easy, 51.25% moderate, 7.5% difficult and 13.75 very difficult. These results form the basis of the importance of the hierarchy of teacher understanding in depth, especially in relation to the preparation of HOTS-based assessment instruments because the quality of learning success is largely determined by the assessment instrument used. Conclusions: The LOTS and HOTS-based capability instruments made by the teacher at 8 East Dijakarta Elementary Schools have not been maximized and need development by these teachers.","PeriodicalId":33216,"journal":{"name":"Bioeduscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46516548","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}
