The Islamic capital market is an alternative source of funding as well as an investment vehicle for a company whose operational activities are based on sharia principles. In this case the Islamic capital market affects the level of economic growth of a country.  where when the level of investment is high, the country's economic growth will increase and vice versa. The purpose of this study is to determine the role of the Islamic capital market in increasing economic growth in Indonesia. This research uses the literature study method with sources from articles, books and data analysis using descriptive analysis regarding the role of the Islamic capital market in increasing economic growth in Indonesia. The results of the study show that Indonesia's economic growth is inseparable from the role of Islamic stock investment. Economic growth can be measured with the value of Gross Domestic Product (GDP). GDP  continues to increase over the past few years, as well as the sharia stock market capitalization which is quite stable. Where is the relationship between capitalization Islamic stock market with a positive Gross Domestic Product (GDP).

Indonesia is rich in culture. The diverse traditional local cultures provide materials to be explored and linked to mathematics learning. The ethnomathematics is a scientific approach that connects mathematics and culture. This study aims to provide an overview and rationalization of the importance of the role of ethnomathematics in multicultural education. As a result, it can be studied because culture is introduced not only through the social sciences but also through the exact sciences via mathematics. The research method in this study is qualitative, using the systematic mapping study method or systematic analysis study to describe the research mapping on ethnomathematics that has been studied. The following are the findings of the research: (1) Various traditional local cultural media, such as traditional houses, woven products, batik, and others, are the media that are widely studied using ethnographic and descriptive qualitative research. The research subjects were cultural experts or descendants of royal lineages. Very little research provides examples of the use of materials in the classroom and according to their measurement capacity. (2) The ethnomathematics plays a role in a multicultural education by exploring various cultures so that students can get to know the multiculturalism of Indonesian nation. The meaningfulness of the mathematics learning and culture is used to make the learning effective in multicultural classrooms.

The students’ problem solving abilities in science about the alternative energy resulted in a low level. A few of the causes were the teacher-centered method and the lack of students' creativity development opportunity in the learning process. This study aims to determine the effect of applying the STEAM approach using the Project-based Learning (PjBL) learning model to aid the students' problem solving abilities about the alternative energy material. This type of research is a quantitative experiment with a quasi-experimental design. The research was conducted at Ngaglik 1 Batu Elementary School in the even semester of the 2022/2023 academic year. The population was grade 5 students, and the samples were taken with purposive sampling technique. There were 28 students in the control class and 29 students in the experimental class. The data was collected using the pretest and posttest instruments. The pretest and posttest results were analyzed by parametric inferential statistics based on the prerequisite tests. The normality test used the Shapiro-Wilk and the homogeneity was tesedt using the Levene Statistics. The Independent Sample t-test was used to analyze the research problem and obtained Sig. (2 tailed) of 0.000, which meant that there was a significant difference in the posttest data in the control and experimental classes, so that the application of STEAM-PjBL learning model is concluded to be able to improve students' problem solving abilities.

The purpose of this study was to develop the electronic student worksheets (E-LKPD), based on the Science, Environment, Technology, and Society (SETS), in improving the learning activities of elementary school students. In this Research and Development (R&D) designed research, the data collection techniques used were the questionnaires, tests, and documentation. The data was analyzed with SETS elements, the e-worksheet validity test was measured by the experts validation, the learning practices were measured using the student and teacher observations lists, the effectiveness of the e-worksheet was tested using the independent sample t-test and the students' cognitive mastery test scores. The results showed that the SETS -based e-worksheet was valid, practical, and effective in increasing students’ learning activities. It can be concluded that: 1) the e-worksheet is valid as the average score from the expert validation resulted 93.5% in a ‘very good’ category and can be used without revision; 2) the e-worksheet is practical, proved by the observation result in the experimental class students that reached  88%, compared to the control class with 72 % score. The results of the students’ responses scored 81% in ‘good’ category and 93% in the experimental class in a ‘very good’ category; 3) the e-worksheet proved to be effective shown by the t-count which was higher than the t-table (2.619 > 1.995), that made the H0 was rejected, that suggested there was a difference in the result of cognitive learning in the experimental (91.4% ) and control class (80%).

Penelitian ini menerapkan dua metode regresi yaitu Decision Tree dan linear berganda untuk memprediksi Body Mass Index (BMI) berdasarkan variabel-variabel lainnya pada dataset Asthma. Metode Decision Tree merupakan salah satu cara data processing dalam memprediksi masa depan dengan cara membangun klasifikasi dan regresi model dalam bentuk struktur pohon. Analisis regresi linear berganda merupakan model regresi yang melibatkan lebih dari satu variabel independen. Analisis regresi linear berganda dilakukan untuk mengetahui arah dan seberapa besar pengaruh variabel independen terhadap variabel dependen. Untuk mengukur tingkat keakuratan model peramalan, digunakan suatu ukuran keakuratan MAPE (Mean Absolute Percentage Error). Hasil MAPE menunjukkan nilai rata-rata prosentase kesalahan mutlak dari nilai sebenarnya dengan nilai peramalan. Pada penelitian ini, metode regresi linear berganda menunjukkan hasil yang lebih baik dengan nilai MAPE berturut-turut sebesar 12,737%; 12,76%; 12,89%; dan 12,99% untuk proporsi data uji berturut-turut 10%, 20%, 30%, dan 40% sedangkan nilai MAPE dari metode regresi Decision Tree sebesar 12,758%; 12,79%; 12,92%; dan 13,13%. Apabila digunakan ukuran kebaikan yang lain seperti MAE dan RMSE akan memberikan hasil yang analog, sedangkan ukuran kebaikan R2 berkebalikan. Penelitian ini dapat dilanjutkan dengan membandingkan hasil yang diperoleh dengan menggunakan metode lain dalam machine learning seperti Support Vector Machine (SVM), random forest, Artificial Neural Network (ANN), dan lain-lain.
