One equilibrium model that describes the relationship between return and risk assumes that the expected return is influenced by more than one macroeconomic factor. Furthermore, the causal relationship between stock returns and macroeconomic factor returns was analyzed using VAR. The application of VAR in this study is to predict stock returns through the stages of checking data stationarity, determining the optimal lag length, testing Granger causality between variables, estimating VAR model parameters and Portmanteau diagnostic tests, and predicting stock returns. The results show that the VAR (1) model is the most appropriate model to describe the relationship between stock returns and macroeconomic factor returns with a significant model owned by BBCA, ICBP, INTP, KLBF, and SMGR stocks. Furthermore, the VAR (1) model is used to predict the five stock returns. The prediction results show that INTP's stock returns are negative while the returns of the other four stocks are positive. This shows that INTP shares experienced a capital loss, while the stock returns of BBCA, ICBP, KLBF, and SMGR experienced capital gains","PeriodicalId":33723,"journal":{"name":"Edu Sains Jurnal Pendidikan Sains dan Matematika","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88587600","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 study aims to determine the effect of LAPS-Heuristic on the mathematical problem solving ability of SMPN 3 Kasokandel students. This study uses a mixed approach (mixed method) with data collection through test questions in the form of posttest, student response questionnaires, and documentation.

Penelitian bertujuan mengetahui karakteristik kimia (total asam, total fenol, total gula, pH, alkohol) dan aktivitas antioksidan kombucha cascara kopi arabika selama fermentasi.

Hasil penelitian menunjukkan total asam, total fenol, alkohol dan IC50 kombucha cascara semakin meningkat dengan waktu fermentasi 4-14 hari yaitu total asam berkisar 1,02-1,51% peningkatan total asam terjadi karena metabolisme sukrosa oleh bakteri dan kapang yang akan menghasilkan sejumlah asam organik dan alkohol yang diproduksi secara anaerob oleh khamir Saccharomyces cerevisiae sehingga terjadi kenaikan alkohol berkisar 48,41-2377,55 ppm. Total fenol berkisar 13,31-22,37 mg GAE/mL, kenaikan total fenol diduga karena terbentuknya senyawa fenolik akibat aktivitas enzimatis oleh mikroba SCOBY kombucha dalam mendegradasi komponen matriks lainnya dan mengakibatkan kenaikan IC50 berkisar 52,021-262,298 mg/L. Total gula dan nilai pH kombucha cascara yang dihasilkan semakin lama fermentasi akan menurun dengan total gula berkisar 2,85-6,15% dan nilai pH berkisar 1,46-2,98, gula yang ada digunakan sebagai sebagai nutrisi oleh kultur kombucha selama fermentasi dan menghasilkan alkohol dan asam organik hal ini mengakibatkan adanya penurunan total gula dan pH pada kombucha cascara.","PeriodicalId":33723,"journal":{"name":"Edu Sains Jurnal Pendidikan Sains dan Matematika","volume":"26 5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75681926","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}
