PT Unilever Indonesia's stock price swings. This has a heteroscedasticity impact due to the substantial volatility of stock prices. The Box-Jenkins ARIMA method can produce accurate predictions, but it is less precise when used to predict data that has a heteroscedasticity effect. Therefore, this study uses the ARIMA-GARCH method because this model has the advantage of not seeing heteroscedasticity as a problem but instead using it to create a model. The purpose of this study is to estimate parameters using the ARIMA-GARCH technique to develop the best model using PT Unilever Indonesia's share price data and to forecast PT Unilever Indonesia's share price for the period January 20 to January 28, 2021, using the best ARIMA-GARCH model created. Forecasting results for 7 periods using the best ARIMA-GARCH model are Rp. 7,535.00, Rp. 7,511.00, Rp. 7,497.00, Rp. 7,489.00, and Rp. 7,485, respectively.

West Java is one of the provinces in Indonesia which has a variety of ethnomathematics, one of which is Indramayu. Some of the people of Indramayu still use the traditional rice measurement tool so that it can become an ethnomathematics study. Therefore, the aim of this study is to describe the results of an ethnomathematics study on the use of rice measuring instruments in the communities of several Indramayu regions. This research method is ethnography with five female and one male participants. Data collection was carried out by triangulation, namely documentation, interviews, field notes, and observations. The result of this research is that there is ethnomathematics in the use of traditional rice measurement tools in the Indramayu community. So that further research is needed to apply ethnomathematics to learning mathematics on the topic of introducing volume units, mass units, and fractional numbers in the area.","PeriodicalId":31699,"journal":{"name":"JMPM Jurnal Matematika dan Pendidikan Matematika","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84572598","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}
