This research aims to determine the influence of CPO prices, inflation rates and the Rupiah exchange rate on share prices of companies in the palm oil plantation sub-sector listed on the Indonesia Stock Exchange in 2017-2021. The type of research used is quantitative research with the data source used is secondary data. The sample in this research was 12 oil palm plantation companies using a purposive sampling technique, namely a sampling technique that sets certain criteria. This research uses panel data regression with the selected model, namely the random effect model. The classical assumption tests used include normality tests and multicollinearity tests with t-statistic hypothesis tests, F-statistics and coefficient of determination. The partial research results show that CPO prices have a significant effect on stock prices, the inflation rate has a significant effect on stock prices and the rupiah exchange rate has a significant effect. Meanwhile, the research results simultaneously show that CPO prices, inflation rates and the rupiah exchange rate have a significant effect on stock prices.

Indonesia is entering a critical period for mental health. Research results from the The Indonesia National Adolescent Mental Health Survey (2022), around 15,5 million Indonesian teenagers experience mental health disorders. Students are part of late adolescence and are vulnerable to mental disorders. The binary logistic regression model is used to examine in more depth what variables have a significant effect. So, this research aims to predict mental health of students in the Faculty of Health Sciences, Pekalongan University. This type of research is observasional with a cross-sectinal design. Data were collected using the SRQ-20 via the Google Form platform using simple random sampling of 186 students. There were 130 students who indicated mental health disordes (69,9%). Simultaneously age, gender, major, semester level, mother’s educational level, father’s educational level, social support and dependence on using smartphone influence student’s mental health status (P Value<0,05). Even though only a few variables were partially significant, the precision percentage of the model that could be predicted correctly was 71,5%. The accuracy of the predicted model is quite good, namely student mental health status (y) = -3,720 + 2,403 (Major) – 1,980 (Mother’s Educational Level) + 1,444 (Father’s Educational Level) + 0,888 (Dependence on using Smartphone). Promotive and preventive interventions such as further screening and education to support student’s healthy mental health.

The background of the problem in this study is due to the low problem solving ability of students, where in the learning process educators still use the cerama or discussion method so that during learning students only listen and receive explanations of material without any mastery of relevant competencies and structures. The learning process is still using the revised 2013 curriculum, which requires students to be able to have productivity, creativity, innovation and have activities that can be contributed to social life. The purpose of this study was to determine how much “The Effect of Problem Based learning Model Application on students Problem Solving Ability at MTs Muhammadiyah Alamanda Kec. Kinali. Kab. Pasaman Barat”. This quantitative research uses the type of research Quasy Experimental Design. The population in this study amounted to 60 students, namely all seventh grade students at MTs Muhammdiyah Alamanda. The sample used in this study amounted to 60 students, with random sampling technique if the data was normally distributed and homogeny. The data analysis technique used is a description of the research data, normally, homogeny and hypothesis test. The results showed that testing using the t-test obtained the results of thitung = 13.863 and ttable= 1.6715 and the value of Sig. (2-tailed) = 0.000 at the problem based learning model has an influence on students problem solving skills.

This research was conducted because researchers found that teachers only apply conventional learning models (lectures) so that educators talk more than students. In addition, students rarely pay attention and record the teacher's explanation. Then there was no feedback from students during the question and answer session, and they did not have the courage to express their opinions. The purpose of this study was to determine the effect of the Crossword Puzzle Assisted Team Games Tournament (TGT) Cooperative Learning Model on Student Learning Activeness in PAI Material at SMP N 3 Koto Baru, Dharmasraya Regency. This type of research is quantitative, using Quasy Experiments. The population of this study were all students of class VIII, totaling 40 people. The sampling technique used was to collect UTS values, then normality and homogeneity tests were carried out, then the samples were determined randomly. Data collection using a questionnaire. The analysis technique uses the t-test. The results showed that the average student activity in the experimental class was 112.20 and that of the control group was 77.20. The results of the analysis using the Independent Sample T-test between experimental and control classes obtained a t-count of 10.014 and a t-table of 2.024, and a significance level of 0.000. So it can be concluded that the activeness of students using the Crossword Puzzle-assisted Team Games Tournament (TGT) is better than students using the conventional model (teaching) in class VIII SMP N 3 Koto Baru.

This research was conducted at MTsN 1 Kota Payakumbuh based on several problems that the author found in class VIII MTsN 1 Kota Payakumbuh. This study was motivated by the lack of variety in the learning model applied in class, so that students were less active and felt bored in participating in the learning process, learning outcomes were less than optimal, and did not match what was expected. This research aims to find out how fiqh learning is implemented using the discovery learning model and the effectiveness of implementing the discovery learning model on the fiqh learning outcomes of class VIII students at MTsN 1 Kota Payakumbuh. This research is quantitative experimental research using a quasi-experimental approach. This research is located at MTsN 1 Kota Payakumbuh. The sample in this study consisted of two classes, namely the control class and the experimental class, with sampling using random sampling techniques. The instruments used in this research were observation, learning outcomes tests, and documentation. Based on research results from the N-Gain Score test results, it can be seen that the average score for the experimental class using the discovery learning model is 63.3982 or 63%, which is in the quite effective category. Meanwhile, for the control class whose learning was through lectures, an average of 24.0655 or 24% was obtained, which was included in the ineffective category. This means that there are significant differences in student learning outcomes between classes that use the discovery learning model and classes that do not use the discovery learning model. So, it can be concluded that there is effectiveness in applying the discovery learning model to the Fiqh learning outcomes of Class VIII students at MTsN 1 Kota Payakumbuh.

Diseases of the heart and blood vessels, such as coronary artery disease (heart attack), cerebrovascular disease (stroke), heart failure (HF), and other pathologies, are collectively referred to as cardiovascular disease (CVD). Globally, around 17 million people a year die from cardiovascular disease, with mortality increasing significantly for the first time in 50 years. Has performed an analysis of the performance of the selection algorithm with case studies predicting the determination of the customer's risk profile. Data mining is the extraction of previously unknown or previously hidden patterns from large databases or data warehouses. This study compares data mining classification models Nave Bayes, Decision Tree, Random Forest, KNN, and SVM to find the most effective model for classifying customer profile data. Later, the most accurate model will be proposed as a replacement model for forecasting the customer's risk profile. As a result, the accuracy value obtained is 82.93% and AUC is 0.896. Then accuracy testing is carried out using the rapidminer application. Testing on rapidminer was carried out with the highest accuracy obtained with an accuracy value of 86.64% and an AUC of 0.880.
