Abstract

The purpose of qualitative research is to determine the implementation of risk management and K3 in B3 waste management at UPTD Environmental Laboratory DLH Purwakarta Regency. The source of this research data was obtained from the results of in-depth interviews with the main informant and supporting informants. Using SWOT research analysis (Strength, Weakness, Opportunity, threat) to show that risk management has been implemented thoroughly based on implementation in carrying out services documented in SOPs and Monitoring which is carried out every three months. The application of K3 is in accordance with Permen-LHK No. 23 of 2020 concerning Environmental Laboratories. Obstacles in B3 waste management are inappropriate waste management due to lack of knowledge and certification competition owned by B3 waste managers. Therefore, a B3 waste management strategy was made with a SWOT analysis in the form of providing an education and training budget to obtain B3 waste management competency certification.

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.

Abstract

This research is motivated by the challenge of integrating local cultural values into education, especially in elementary schools, amidst the growing wave of globalization. Cultural preservation and increasing student literacy are two aspects that need to be considered in the teaching and learning process. Therefore, this study aims to develop a digital learning media in the form of a digital pop-up flipbook with cultural content that is valid and practical as an effort to literacy for elementary school students. The research method used is research and development with the ADDIE model, which includes needs analysis, design, development, implementation, and evaluation. Data collection techniques use interview techniques, assessment questionnaires, and observation. Data analysis techniques use descriptive and quantitative analysis techniques. The results obtained from this study are learning media developed in the form of a pop-up flipbook containing the culture of Bangka Belitung which has been tested for media and material validity as well as media practicality. The results of the validity test through three media experts were 88% and the results of the material validity test were 94%. In addition, practicality tests have been carried out through teacher and student response assessments of 81%. Thus, developing digital learning media with cultural content functions as a learning aid and a means to strengthen cultural identity and student literacy.
