Abstract

Abstrak - Data warehouse berguna untuk analisis mendalam dan memperoleh informasi lebih akurat ketika pengambilan keputusan. Penelitian perancangan dan implementasi data warehouse meningkatkan proses pengambilan keputusan sebagai integrasi data dari berbagai sumber, memungkinkan analisis data lebih cepat dan akurat. Studi literatur ini mengulas berbagai pendekatan dalam perancangan dan implementasi data warehouse di berbagai bidang, termasuk penjualan produk tour, perpustakaan universitas, akademik perguruan tinggi, dan analisis kinerja perusahaan. Hasil tinjauan menunjukkan bahwa penerapan metodologi sistematis dan model star schema dapat meningkatkan efisiensi dan akurasi pengolahan data. Penelitian ini dapat memberikan praktisi dalam mengembangkan data warehouse efektif, memfasilitasi akses data cepat dan tepat untuk mendukung pengambilan keputusan yang lebih baik.Kata Kunci: Studi Literatur, Data Warehouse, Nine Step Kimball, Star Schema. Abstract - Data warehouses are useful for in-depth analysis and obtaining more accurate information when making decisions. Data warehouse design and implementation research improves the decision-making process as the integration of data from various sources, enabling faster and more accurate data analysis. This literature review examines various approaches to data warehouse design and implementation in various fields, including product sales tours, university libraries, academic colleges, and company performance analysis. The review shows that the application of systematic methodology and star schema model can improve the efficiency and accuracy of data processing. This research can provide practitioners in developing an effective data warehouse, facilitating fast and precise data access to support better decision making. Keywords: Literature Study, Data Warehouse, Kimball's Nine Steps, Star Schema.

Abstract

The development of technology in the era of Industry 4.0 demands increased competencies in the fields of the Internet of Things (IoT) and microcontrollers, especially for students in Vocational High Schools (SMK). Limited hardware and laboratory facilities are major obstacles in practical learning processes. Therefore, utilizing simulation platforms such as Wokwi becomes an effective solution to support microcontroller-based learning. This training aims to provide basic knowledge of Arduino usage through a simulation project of creating a running text on an LCD I2C using Wokwi for SMK students. The method applied combines theory and practice with a participatory approach, involving 25 participants from the Computer and Network Engineering (TKJ) and Visual Communication Design (DKV) departments. The evaluation was conducted using pre-tests and post-tests consisting of 10 multiple-choice questions to measure participants' understanding before and after the training. The results show a significant improvement in post-test scores, particularly in understanding basic concepts of IoT, microcontrollers, and Arduino programming practices. These findings prove that Wokwi is an effective simulation tool for enhancing basic microcontroller programming skills among beginners. Thus, this training model can serve as an alternative solution to support practical learning in schools with limited physical equipment.
