Abstract

This research is a study that discusses the influence of mathematics on grade VII students—learning outcomes at SMP NEGERI 3 Kota Bengkulu. This study's population was all students of class VII SMP NEGERI 3 Bengkulu City, which consisted of 130 famous students in 5 classes. Samples were taken using the random sampling technique. Then, a sample of class VII.2 was chosen, possibly 20 students. This study using a questionnaire and documentation. The data were obtained using a questionnaire, while the documentation in this study was used to obtain learning data obtained from teacher data in the form of daily math test scores. In the research analysis, prerequisite tests were used, such as the normality test, linearity test, and product moment test with SPSS version 22. The analysis results obtained a value of 0.754, which indicates that the relationship's level is healthy between the two variables. There is a positive sign indicating that the property is valuable. Positive and unidirectional. The results of the analysis using Pearson products when the significance value was obtained 0.000. The results of this study indicate that there is a significant relationship between the effect of mathematics on learning outcomes at SMP NEGERI 3 Kota Bengkulu.Keywords: Mathematics anxiety, learning outcomes

Abstract

Pemecahan masalah matematis merupakan salah satu kemampuan yang harus dimiliki siswa dalam belajar matematika. Tujuan penelitian ini adalah untuk mengidentifikasi, mengkaji, serta membuat kesimpulan terkait keseluruhan dari hasil penelitian yang berkaitan dengan pengaruh gaya kognitif terhadap kemampuan pemecahan masalah matematis siswa pada matematika. Metode penelitian yang dipilih dalam penelitian ini ialah metode SLR (Systematic Literature Review). Pengumpulan data dilakukan dengan mereview semua artikel terkait pemecahan masalah matematis dalam kurun waktu 2017 – 2022. Artikel yang digunakan pada penelitian ini sebanyak 7 artikel jurnal nasional dan internasional terakreditasi yang diperoleh dari Google Schoolar dan SINTA. Berdasarkan penelitian ini didapatkan bahwa tingkat kemampuan pemecahan masalah matematis memiliki hubungan dengan gaya kognitif serta mempengaruhi kemampuan pemecahan masalah matematis siswa. Dalam penelitian ini kemampuan pemecahan masalah di tinjau dari gaya kognitif pada subjek Field Independent (FI) dan Field Dependent (FD). Kemampuan pemecahan masalah matematis siswa berbeda berdasarkan tingkat ditinjau dari gaya kognitif pada mata pelajaran matematika. Mayoritas siswa jenis FI lebih baik dalam menyelesaikan masalah matematis dibandingkan dengan siswa jenis FD.

Abstract

This study aims to analyze the relationship between Environmental, Social, and Governance (ESG) scores and Return on Assets (ROA) in mining sector companies listed and not listed in the SRI-KEHATI index. The background of this research is based on the importance of implementing sustainability principles in company operations and how these principles affect financial performance. This study uses a quantitative approach with descriptive analysis methods and two statistical tests, namely the Independent Sample t-test for the risk variable and the coefficient of variation, and the Mann-Whitney U Test for the return variable. Data was obtained from the company's annual report for the 2019-2023 period. The results showed that companies incorporated in the SRI-KEHATI index have higher ESG scores than companies that are not incorporated. However, there is no significant difference in risk and return between the two groups of companies. In addition, there is a positive trend between increasing ESG scores and financial performance (ROA). The implications of these findings suggest that a commitment to sustainability can strengthen reputation and improve the efficiency and long-term financial stability of companies.

Abstract

This study aimed to develop guided discovery learning-based android learning media to improve critical thinking skills. The developed biology learning media was applied to the nervous system material. The discussion of the physiology of the nervous system is one of the difficult biological materials to understand because it includes the organization and structure of neurons and their functions, ion pump mechanisms when neurons are at rest, action potential mechanisms, mechanisms for neurons to communicate with other cells in the synapses, and organization of the nervous system. This study used research and development (R&D) with a method developed by Thiagarajan, namely the 4D model with stages: define, design, develop and disseminate. The stages of this study are limited to the development stage. The results showed that the media was feasible with media, language, and a material expert validation of   3.5, 3.8, and 3.3, respectively.

Abstract

The purpose of this study was to explore understanding and mastery of the material through exploratory descriptions of students in solving mathematical problems. The method used is descriptive qualitative exploratory with research subjects, namely three students (high, medium and low ability) at the Mathematics tadris, Bengkulu State Islamic Institute (IAIN) who are taking the Calculus 2 course.The main instrument is the researcher himself, while the auxiliary instrument in the form of two problem solving questions from the Derivative Application material that has been validated by previous research and interview guidelines. The data analysis procedure was carried out through a qualitative analysis of the written test results. The results of students' exploratory ability in solving mathematical problems, the average achievement of the assessment is in a good category on the indicator of mathematical exploration ability in the form of mathematically formulating situations and using mathematical concepts. While the indicators of compiling plans and solving mathematical problems are in the moderate category for low students (MR) and in the good category for students with moderate (MS) and high (MT) abilities.
