The rate of return (return) and risk are inseparable in investing activities. 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

TThe ability to solve problems is one of the abilities that students lack mastery of. This results in many difficulties faced when learning mathematics. This problem is not absolutely the student's fault. But the teacher as a facilitator also plays a very important role, one of which is the use of appropriate and efficient learning models to help improve these abilities, namely alternative choices with LAPS-Heuristics. 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. The population used is two classes, namely the control and experimental classes, each of which is 24 students. The findings in this study are the LAPS-Heuristic learning model has an influence on the ability to solve mathematical problems of students by obtaining The level of problem-solving ability of the experimental class is greater than that of the control class, it can be seen from the average per indicator including indicators of knowing and understanding the problem of 90 and 71, indicators of planning problems of 80.25 and 60.5, indicators of implementing plans 87.75 and 67.25 and the indicator rechecked the results of 55.5 and 44. While the results of student responses are mostly positive with the acquisition of 90% and negative by 24%.

Kulit kopi yang dikeringkan (cascara) dapat dimanfaatkan menjadi minuman seduhan layaknya teh. Pengembangan cascara sebagai minuman fermentasi (kombucha) banyak dilakukan. Kombucha merupakan minuman fermentasi larutan cascara dan gula yang ditambahkan starter kombucha yaitu simbiosis bakteri Acetobacter xylinum dan beberapa jenis khamir diantaranya Saccharomyces cerevisiae. Penelitian bertujuan mengetahui karakteristik kimia (total asam, total fenol, total gula, pH, alkohol) dan aktivitas antioksidan kombucha cascara kopi arabika selama fermentasi. Penelitian ini dilakukan dengan Rancangan Acak Lengkap dengan satu faktor yaitu lama fermentasi (4, 8, 10, 12, dan 14 hari). Analisia sidik ragam untuk pengaruh perlakuan dilakukan pada data yang diperoleh, bila hasil menunjukkan berpengaruh nyata, maka dilakukan uji Duncan. 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.

The material for culturing and coloring bacteria is abstract, requiring other alternatives to understand the material through a practicum in a virtual laboratory. This development research aims to produce virtual laboratory media for high school students. The media development was carried out using the ADDIE model. Media and material experts' and product validation obtained results in a very good category. The feasibility of this virtual laboratory media was practically seen through the results of the teacher's response which is in the excellent category, and the analysis of the perception of small group students is in a good category. Trials for large groups of students were performed in the two classes of MIA. The obtained result was in an excellent category, with Choen's Kappa index of 0.47 (significant 0.00), indicating a fairly strong and significant agreement on the students' responses in both classes regarding the feasibility of the developed virtual laboratory media. It can be concluded that the virtual laboratory media on culturing and coloring bacteria is feasible to be used in schools as an alternative to practicum learning media.

Students' efforts in studying physics often encounter obstacles due to the assumption that physics is a difficult subject to understand and teaching physics tends to be less interesting, causing misconceptions. This study aims to identify the misconceptions experienced by students in static fluid and dynamic fluid materials through four-tier (four-tier) diagnostics. This study uses a quantitative description method, with respondents as many as 30 students of class XI MIA MAN Insan Cendekia Jambi. The results showed that the average misconception experienced by students was classified in the low category because the percentage of correct answers for all levels obtained was 12.4% and the percentage of students' misconceptions for all levels was 2.0%. In addition to misconceptions, there are still some students who belong to the Lack of Knowledge category, which is 8.67% including false positives of 43.20% and false negatives of 40.27%. This can happen because students do not understand the concept or it could be because students are not serious about working on the questions given.
