Students often find difficult and less interested in mathematics, thus it is necessary to test students learning interests. The purpose of this study is to determine the level of validity and reliability of a learning interests questionnaire. Students' interest in mathematics questionnaires can be given to students if their validity and reliability have been tested. In this study, the validity test was carried out with the product-moment correlation formula. The reliability test was carried out with the Cronbach Alpha coefficient formula. This research was conducted on a sample of 89 students of class VIII SMPN 7 Depok. Based on the results of the validity test, it was found that 27 questions were valid and 3 questions were invalid so they were eliminated. Then the reliability test results were 0.752, which was more than 0.70, indicating that the questionnaire was reliable. From the results of the validity and reliability tests, it can be concluded that the questionnaire in this study can be used for further research.

Improving the quality of education is strongly influenced by teacher’s competence, including the ability to write scientific papers based on research. However, many teachers face challenges in analyzing quantitative data due to limited knowledge of statistical tools such as SPSS. To address this issue, this Community Service Program (PkM) aimed to strengthen teachers' capacity in conducting data analysis using SPSS, with a focus on simple linear regression techniques. The activity took place at a private Junior High School in Jatinegara, East Jakarta, applying a participatory action research approach. The program included socialization, technical training, mentoring, and evaluation. The results indicated an increase in teachers’ understanding of identifying variables, entering data, and analyzing and interpreting regression results. Teachers also showed strong motivation in developing research ideas and writing scientific papers systematically. This activity not only improved their technical data analysis skills but also encouraged greater participation in scientific publication. The program contributes positively to teacher professionalism and holds potential for replication in other schools.

The limited ability of vocational high school (SMK) teachers in East Jakarta to apply advanced statistical analysis has resulted in low-quality educational research outputs. Therefore, this community service program aims to enhance teachers’ competence in understanding and applying path analysis using the SPSS statistical software. The program was implemented through four main stages: preparation, core implementation, mentoring, and evaluation. The adopted approach combined lectures, workshops, hands-on practice, and mentoring to equip participants with both conceptual understanding and practical skills. The results showed a significant improvement in teachers’ abilities, with more than 80% of participants able to explain the basic concepts of path analysis and independently perform data processing. Participants also successfully produced simple analytical reports based on simulated data, reflecting their increased research skills. Based on evaluation results and positive participant responses, the training method proved to be effective and applicable in supporting data-driven research among SMK teachers in East Jakarta. This activity is expected to serve as an initial step in fostering a culture of data-based research within vocational schools and to encourage teachers to further develop their research capacity through advanced training and inter-school collaboration.

Programme for International Student Assessment (PISA) reported that many countries, including Indonesia, have not yet reached the expected levels of mathematics proficiency, highlighting the importance of examining internal factors such as students’ learning interest. This study aims to examine students’ learning interest and how it relates to and predicts their mathematics achievement. This quantitative correlational study involved 65 randomly selected seventh-grade students from SMPN 160 East Jakarta, Indonesia. Learning interest was measured using a validated 20-item questionnaire, and mathematics achievement was obtained from mid-semester test scores. Data were analyzed using descriptive statistics, Spearman’s correlation, and rank-based and multiple regression analyses in SPSS 27. The results showed that students generally had moderate levels of learning interest (M = 3.65) and mathematics achievement (M = 78.94). Learning interest was positively related to mathematics achievement (r = 0.64) and significantly predicted students’ mathematics performance (R² = 0.52), with persistence (p = 0.03) and attention (p = 0.04) being the strongest predictors. In conclusion, students’ persistence and attention are key factors in mathematics achievement, indicating that sustained focus and perseverance play a central role in improving mathematics performance.
