Abstract

Physics is a fundamental course taught to Computer Science students at the university level, even though it is not directly related to programming. This study aims to identify the challenges faced by students in understanding Physics, analyze the causes of these difficulties, and evaluate students' perceptions regarding the relevance of Physics in the field of Computer Science. The research employed a descriptive quantitative method using a Google Form questionnaire. A total of 30 Computer Science students from the State Islamic University of North Sumatra participated as respondents. The results show that most students experience difficulties in understanding Physics, mainly due to the abstract nature of the material, lack of practice (78.8%), and explanations that are not contextual. Many students also felt that their Physics skills had not significantly improved during their studies. Nevertheless, they acknowledged the importance of Physics, especially in fields such as robotics, simulation, and game development. Respondents also expressed enthusiasm for contextual and digitally supported learning approaches. Proposed solutions include implementing contextual learning that connects Physics to Computer Science applications, utilizing visual media and simulations, and improving pedagogical training for lecturers. These approaches are expected to enhance comprehension, interest, and the perceived relevance of Physics among Computer Science students.

Abstract

Kemajuan teknologi terkini telah memicu peningkatan penggunaan kartu kredit yang signifikan, sehingga meningkatkan persentase penipuan kartu kredit baik dalam transaksi offline maupun online. Meskipun langkah-langkah seperti kode PIN, chip tertanam, dan kunci tambahan seperti token telah meningkatkan keamanan kartu kredit, lembaga keuangan dituntut untuk memperkuat kontrol penggunaan dan menerapkan sistem pemantauan waktu nyata untuk segera mengidentifikasi dan mengurangi aktivitas yang mencurigakan. Karena semakin populernya transaksi non-tunai, penipuan kartu kredit telah menjadi salah satu penipuan yang paling umum dan menyebabkan kerugian besar bagi lembaga keuangan dan individu dalam kehidupan nyata. Deteksi transaksi penipuan harus sangat cepat dan efektif. Ada lebih dari satu juta transaksi yang terjadi setiap hari, dan sulit untuk menyatukan setiap transaksi secara individu. Dengan demikian, sistem deteksi penipuan yang efektif digunakan untuk membedakan transaksi asli dan penipuan. Dalam jurnal ini, algoritma Support Vector Machine (SVM) digunakan untuk membangun model untuk menangani masalah deteksi penipuan kartu kredit. Penelitian ini menghasilkan kinerja algoritma Support Vector Machine (SVM), dalam mengidentifikasi transaksi keuangan yang mencurigakan. Penelitian ini bertujuan untuk mengembangkan model deteksi penipuan yang akurat dan efisien dengan memanfaatkan algoritma SVM. Dalam penelitian ini, data transaksi online maupun offline yang terdiri dari transaksi sah dan penipuan akan digunakan sebagai dataset. Proses penelitian meliputi tahapan preprocessing Data, model pelatihan dengan manfaat SVM, dan penilaian kinerja model berdasarkan ukuran akurasi, presisi, recal,dan F1-score. Diharapkan model yang dibuat dapat mengidentifikasi penipuan dengan akurasi yang tinggi dan dapat diterapkan secara efisien dalam sistem transaksi baik online maupun offline untuk meningkatkan keamanan dan kepercayaan para pengguna.
