Abstract

Mathematics learning activities at SD Negeri 230 Maluku Tengah is a form of community service activity from a series of Teaching Assistance activities carried out by Pattimura University. From the results of the mathematics learning activities on 28 students in grade 5 and grade 6 at SD Negeri 230 Maluku Tengah, it was found that there was a significant increase from the pre-test results. Where the value of the post-test results is higher than the pre-test results, then according to statistics descriptive there is a difference in the average student learning outcomes before being given training (pre-test) with student learning outcomes after being given training (post-test). The test results with the pair sample test method obtained a significance value (Sig.) of 0.038 <0.05, so it can be concluded that there is a real difference (significant) in the average between the pre-test and post-test learning outcomes. Apart from that, learning materials raised from the local context also encourage and facilitate students in understanding the process of learning mathematics based on local wisdom

Abstract

Persamaan diferensial telah menjadi salah satu topik matematika yang menarik pada kemajuan ilmu pengetahuan dan teknologi. Salah satu bentuk aplikasinya, yaitu pada penyebaran penyakit menular. Pada kenyataannya, pembelajaran matematika di sekolah masih bersifat teoritis, sehingga pembelaran bermakna sulit tercapai. Materi matematika yang diberikan oleh guru sulit untuk dipahami oleh siswa karena bersifat abstrak. Hal ini mendorong pembelajaran untuk mengaplikasikan materi tentang persamaan diferensial pada kehidupan nyata di sekitar siswa. Selain itu, pesatnya kemajuan ilmu pengetahuan dan teknologi menuntut adanya kemampuan adaptasi dari siswa, guru, dan sekolah. Melalui kegiatan pengabdian ini, upaya adaptasi terhadap perkembangan ilmu pengetahuan dan teknologi dilakukan melalui peningkatkan kualitas pembelajaran pada SMA Negeri 3 Ambon. Kegiatan yang dilakukan meliputi upaya meningkatkan kemampuan siswa tentang penerapan materi persamaan differensial pada kehidupan nyata. Pada akhirnya, Software Maple digunakan untuk mendukung proses pembelajaran matematika.

Abstract

This article develops a mathematical model for studying the impact of public awareness and intervention strategies on alcohol consumption patterns. To protect populations from addiction, we are focusing on educational campaigns and interventions. Alcohol consumption cases decrease as the model variable awareness susceptible class is increased through awareness campaigns and interventions. The nonnegativity and boundedness of the model's solutions are analyzed. A qualitative analysis of the model's equilibrium points and the alcohol reproductive number, R0, was performed. Global stability was analyzed for alcohol consumption at the positive equilibrium point via a suitable Lyapunov function. When the alcohol reproductive number (R0) is less than one, the alcohol-free equilibrium is globally asymptotically stable; otherwise, it is unstable. Although educational campaigns protect vulnerable people, their impact on the model is substantial. The simulation shows that the intervention directly and drastically reduces the target alcoholic population.

Abstract

Professional scientific journal management requires transparent, inclusive, and data-driven governance practices, including in terms of author involvement based on gender. This article aims to analyze the involvement of male and female authors in Berekeng journal publications as part of the reflection and contribution of the scientific journal management profession. The method used is quantitative descriptive analysis that analyzes the dynamics of gender participation in scientific publications during the 2007–2025 period. The results of the study show that the 2007–2018 period was significantly dominated by male authors (peaking at 84.44% in 2018). However, there was a rapid transition towards balance in 2019–2021, where female participation began to prevail (54.63% in 2021). This pattern continued in the 2023–2025 period, showing a new significant dominance by female authors (peaking at 56.45% in 2024). Overall, the total number of female authors (50.81%) slightly exceeded that of male authors (49.19%). This dramatic shift implies a fundamental change in the academic community. Specifically in the context of Mathematics, this trend is predicted to encourage diversification of research topics into Applied Mathematics and Data Science, strengthen interdisciplinary collaboration, and create a more inclusive research environment. This study concludes that gender equality efforts have fundamentally changing the landscape of publishing. These activities are expected to strengthen the capacity of journal managers in implementing data-driven management while promoting fair and sustainable scientific publishing practices as a tangible manifestation of professional dedication in the field of scientific journal management.

Abstract

This study was conducted as part of the Internship Program (PKL) of the Statistics Study Program, carried out in the administrative editorial management division of the BAREKENG Journal. The activities included collecting and processing publication data to support the evaluation of editorial performance and the mapping of the journal’s internationalization process. This research aims to analyze trends in the diversity of domestic and international authors in BAREKENG Journal publications during the 2007–2025 period. The data were obtained from the journal’s publication archives and processed through several stages, including author affiliation classification, grouping by publication period, and analyzing the development of domestic and international author proportions. The analysis was conducted using descriptive quantitative methods and presented in the form of trend graphs. The results show that the number of domestic authors increased significantly after 2020, reaching 864 authors in 2025. Contributions from international authors first appeared in 2021 and continued to grow, with the highest number recorded at 61 authors in 2025. These findings indicate that the BAREKENG Journal is not only growing at the national level but is also beginning to attract attention from the international academic community. This study is expected to provide an overview of the dynamics of author contributions and the journal’s position in the internationalization process, as well as serve as a basis for strengthening future journal management strategies.
