The sample of this research was 70 learners from two different classes who were randomly selected with purposive sampling techniques. The selected class is used as an experimental class using the discovery learning model and other classes as a control class using a conventional learning model. The data in this research were obtained from the results of the initial test and the final test of mathematical communication ability carried out before and after learning. The data will be analyzed using homogeneity test, normality test, independent sample T-test and paired T-test. The research conducted shows that: (1) The learning model applied to each class can have an influence on mathematical communication abilities. This is evidenced by the increase in the final test results given after learning (2) a learning model that allows students to actively participate in learning activities is not necessarily better than conventional learning models. This is shown by the similarity between the final test scores of the experimental class and the control class.","PeriodicalId":123617,"journal":{"name":"Daya Matematis: Jurnal Inovasi Pendidikan Matematika","volume":"81 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120874640","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 model consists of six population compartments, namely susceptible to infection with hepatitis B or Susceptible, Exposed, infected with acute hepatitis B or Acute Infected , infected with chronic hepatitis B or Chronic Infected, suffering from liver cirrhosis or Liver Cirrhotic, and infected who are recovering or Removed. The system is solved by using Pontryagin's minimum principle and numerically by the forward-backward sweep method. Numerical simulation of the optimal control shows that with vaccination , campaign on hepatitis B, and treatment, the spread of hepatitis B can be eradicated more quickly. The implementation large amounts of vaccination, campaign on hepatitis B, and treatment need to be carried out from the start and the proportion can be reduced until a certain time is no longer necessary.

Ethnomathematics is the study of mathematics as it appears or is utilized in cultural community groups such as urban and rural communities, children of a specific age, labor groups and indigenous peoples. For the vast majority of Indonesians, cultivation is a way of life, particularly the residents of Nanga Mahap Village. Mathematical words are employed in farming activities, ranging from units to fundamental mathematical concepts. Cultivation systems have been practiced in grasslands and forests around the world. Cultivation is a shifting cultivation system from one plot of land to another, usually cleared by cutting down and burning part of the forest to make fields.
