Abstract

This research elucidates the application of the exponential smoothing method in forecasting profit figures for Lutfia MS Glow Skincare. This method was chosen due to its capability to adapt data using the alpha value, along with continual refinement based on exponentially smoothed historical averages. With an explanatory purpose, the study collected profit data from 2020 to 2022 at Lutfia MS Glow Skincare. The single exponential smoothing technique was employed to develop a profit prediction system, enabling the identification of sales trends and evaluation through metrics like Mean Absolute Error (MAE) and Mean Squared Error (MSE). The approach offers simplicity in implementation while providing relatively accurate results, especially for short-term forecasting. This makes it particularly useful in retail and skincare business contexts, where sales figures can be volatile due to seasonal demands or market fluctuations. By utilizing exponential smoothing, the research helps reduce forecasting errors and provides actionable insights for business planning. The result of the analysis showed a reasonably low error margin with a Mean Absolute Percentage Error (MAPE) of 3.65%, indicating high prediction accuracy. The research outcomes furnish skincare resellers and decision-makers with practical guidance in planning inventory, managing supply chains, and executing marketing strategies, ultimately supporting better data-driven decisions in a competitive industry.

Abstract

This study addresses students' lack of understanding regarding the ethics of using Generative AI (Gen AI) in academic activities. This guidebook serves as a response to the increasing integration of generative AI technology in education, which requires students to adopt AI technology and use it responsibly and ethically. This study uses the Research and Development (R&D) method with the 4D development model (Define, Design, Develop, and Disseminate). The research stages include content and technical needs analysis, content design and guidebook framework, development and limited trials with eight student representatives, validation of the guidebook's feasibility by experts and users, and dissemination of the guidebook to the target audience. The results show that experts consider this practical guidebook appropriate, with a Likert scale score of 3.6 for content, visuals, and technical aspects. The evaluation results show that 91.7% of students agree that this guidebook provides comprehensive information on the ethical use of Gen AI, and 66% of students agree that this book provides clear guidance for academic activities. This practical guidebook successfully addresses students' lack of understanding regarding the ethical use of Gen AI in academic activities. The student-centered approach is relevant, applicable, and potentially integrated into courses such as digital literacy or academic methodology. Further extensive testing and continued content development are recommended to align with technological updates for further research and broader implementation.

Abstract

Perkembangan teknologi dalam era Revolusi Industri 5.0 telah mendorong transformasi pembelajaran dari metode konvensional ke pembelajaran daring. Salah satu platform yang banyak digunakan dalam pendidikan online adalah Zoom Meeting, yang menyediakan fitur Breakout Room untuk meningkatkan interaksi dan diskusi mahasiswa dalam kelompok kecil. Penelitian ini bertujuan untuk mengevaluasi efektivitas Breakout Room dalam pembelajaran mata kuliah Ketentuan Umum dan Tata Cara Perpajakan (KUP) dengan mengukur tingkat pemahaman, kerja sama, serta keterlibatan mahasiswa dalam diskusi akademik. Penelitian ini menggunakan pendekatan kuantitatif dan kualitatifdengan kuesioner berbasis skala Likert dan pertanyaan terbuka yang dikumpulkan dari 49 mahasiswa peserta kelas KUP. Hasil penelitian menunjukkan bahwa 85% mahasiswa merasa metode ini meningkatkan pemahaman mereka terhadap konsep perpajakan, sementara 80% menyatakan lebih nyaman berdiskusi dalam kelompok kecil. Selain itu, 75% mahasiswa merasa bahwa metode ini meningkatkan kerja sama tim dalam menyelesaikan kasus pajak. Namun, masih terdapat tantangan seperti keterbatasan durasi diskusi, koordinasi dalam kelompok, serta preferensi mahasiswa yang lebih nyaman dengan pembelajaran individu. Dengan demikian, penelitian ini merekomendasikan penyesuaian durasi diskusi, kombinasi dengan metode pembelajaran lain, serta evaluasi berkala untuk meningkatkan efektivitas Breakout Room dalam pembelajaran perpajakan. Penelitian selanjutnya dapat mengeksplorasi pengaruh metode ini terhadap hasil akademik mahasiswa secara kuantitatif serta menguji efektivitasnya dalam berbagai mata kuliah lain yang berbasis analisis kasus.
