Abstract

Traditional marketing strategies are no longer practical to implement because the process requires more costs and time to disseminate information which is much longer. Data Mining is a science that discusses knowledge from previous data to estimate the amount of production in the future. Data mining is a term used to find hidden knowledge in databases. “Data mining is a semi-automatic process using statistical, mathematical, artificial intelligence, and machine learning techniques to extract and identify valuable and helpful information in large databases. It is necessary to solve the problem by using one of the five methods in the field of Data Mining, namely the Multiple Linear Regression method, where this method will analyze the variables that have an influence and can make estimates. Multiple Linear Regression Is a method that can be used to analyze data and obtain meaningful conclusions about a relationship between one variable and another. This relationship is generally expressed by a mathematical equation expressing the relationship between the independent and dependent variables in the form of a simple equation

Permasalahan yang terjadi di Panti Asuhan Putera Muhammadiyah Medan adalah belum adanya Sistem Informasi yang mengelola dan memanajemen bantuan sosial dari para donatur dengan efektif dan efisien karena masih menggunakan pembukuan dengan cara manual. Sistem Informasi Panti Asuhan Putera Muhammadiyah Kota Medan bertujuan memudahkan panti asuhan dalam memanajemen bantuan sosial dari para donatur agar menjadi lebih efektif dan efisien dalam pengelolaan bantuan sosial. Dengan penerapan dan sosialisai sistem informasi, sistem yang dibangun mengintegrasikan beberapa aspek penting dalam Panti Asuhan yaitu pengelolaan data bantuan sosial, pengelolaan anak panti, pengelolaan donatur dan proses donasi yang biasanya dilakukan secara manual. Kedepannya dengan adanya sistem, pengelolaan data tersebut dan proses donasi akan menjadi lebih efektif dan efisien. Sistem yang dibangun dengan User Interfaceberbasis web mulai dari pembuatan website panti asuhan dan sistem berbasis web untuk proses donasi dengan proses transfer langsung ke rekening Panti Asuhan dan proses payment gateway melalui payment Virtual Account seperti Mobile Banking, Internet Banking dan E-Wallet seperti transfer melalui OVO, Gopay dan lain sebagainya. Selain itu juga, sistem yang dibangun akan menjaga privasi dan kerahasiaan data kas keuangan panti asuhan. Manfaat dari Penerapan Sistem Informasi Panti Asuhan Putera Muhammadiyah Kota Medan diharapkan dapat membantu berbagai program sosial di panti asuhan dan mendukung dalam pengelolaan bantuan sosial dari para donatur agar menjadi lebih efektif dan efisien dan pembukuan tersistem dengan baik.

Abstract

The integration of computer-based simulations in electrical engineering education enhances students' understanding of complex concepts such as Geometric Mean Radius (GMR) and Geometric Mean Distance (GMD) in transmission line systems. This study aimed to develop and evaluate a MATLAB-based simulation tool to support learning in voltage regulation and efficiency analysis. Adopting a Research and Development (RD) methodology guided by the ADDIE model, the simulation was tested with 32 electrical engineering students. Expert validation, conducted by three power systems professors and two instructional technology specialists, confirmed high content validity (average score 85%). Data analysis using SmartPLS revealed that simulation quality significantly influenced both conceptual understanding (β = 0.903) and learning effectiveness (β = 0.977), with strong model fit (R² = 0.846). Students’ comprehension of voltage regulation and efficiency improved significantly, as indicated by N-gain scores of 0.75 and 0.72, respectively, while parameter analysis proficiency rose from 42.8% to 80.7%. These findings suggest that the simulation tool not only enhances academic learning but also offers industrial benefits. Specifically, it provides power utilities with a cost-effective means to optimize transmission line designs, reducing iteration costs by up to 60%. It also enables rapid prototyping of conductor configurations and serves as a standardized platform for professional training. Furthermore, the tool supports sustainable energy efforts by improving the integration of renewable energy sources through optimized line parameter analysis.

Abstract

The rapid development of information technology has brought human civilization into the 21st century, which requires mastery of 21st-century skills, such as critical, creative, collaborative, and communicative thinking. Virtual reality offers an immersive and interactive learning experience, allowing students to interact with virtual environments as if they were real, thus potentially increasing conceptual understanding and learning motivation. Virtual reality has advantages and disadvantages in science learning. Where the purpose of the study is to examine the advantages and disadvantages of virtual reality in science learning systems in the 21st century: a Review, namely collecting information from previous studies related to the Advantages and Disadvantages of Virtual Reality in Science Learning Systems in the 21st Century This review was conducted based on the review method. The results of this study explain that there are several advantages and disadvantages of using a science learning system that uses virtual reality, one of the results that explains the advantages of virtual reality is Immersive Learning so that students can see learning concepts more realistically and not only focus on books or material explanations; teachers and one of the disadvantages of virtual reality in science learning is that VR systems can be expensive to develop and maintain, making them less accessible to organizations, educational institutions with limited budgets.

Abstract

Perkembangan teknologi informasi telah mendorong transformasi dalam pengelolaan dokumen administrasi melalui penerapan sistem e-persuratan. Namun, proses klasifikasi dokumen yang masih dilakukan secara manual sering menimbulkan kesalahan dan keterlambatan dalam pengelolaan dokumen. Penelitian ini bertujuan untuk menganalisis efektivitas penerapan algoritma Decision Tree dalam meningkatkan kecepatan dan akurasi pengelolaan dokumen pada sistem e-persuratan. Metode penelitian yang digunakan adalah pendekatan kuantitatif eksperimental dengan tahapan meliputi pengumpulan data, pra-pemrosesan, pembagian dataset, pembangunan model, serta evaluasi kinerja menggunakan metrik akurasi, precision, recall, dan F1-score. Hasil penelitian menunjukkan bahwa algoritma Decision Tree mampu mencapai tingkat akurasi sebesar 83%, dengan nilai precision 82%, recall 81%, dan F1-score 81,5%. Selain itu, penerapan algoritma ini juga mampu meningkatkan efisiensi waktu pemrosesan dokumen hingga sekitar 66% dibandingkan metode manual. Temuan ini menunjukkan bahwa Decision Tree efektif dalam meningkatkan kinerja sistem e-persuratan, baik dari segi kecepatan maupun akurasi. Dengan demikian, integrasi algoritma Decision Tree dapat menjadi solusi strategis dalam mendukung pengelolaan dokumen yang lebih efisien, akurat, dan berbasis teknologi.
