Abstract

The problem of student graduation in higher education is one of the most essential things in showing the quality of learning in higher education, especially on the Sumbawa University of Technology (UTS) campus. The purpose of this research is to compare three algorithm methods, namely C4.5, Naive Bayes, and K-Nearest Neighbor (KNN), which is better at predicting the timeliness of student graduation using RapidMiner tools with the Knowledge Discovery in Database (KDD) method. The dataset used by the three classifications is 330 Informatics student data. Based on the comparison of the three algorithms with data splitting techniques, it is found that the C4.5 algorithm produces an accuracy of 73.49% with a precision of 64.62% and a recall of 41.89%. The Naive Bayes algorithm produces an accuracy of 72.79% with a precision of 64.06% and a recall of 38.11%. Meanwhile, the K-Nearest Neighbor (KNN) algorithm produces an accuracy of 76.08% with a precision of 73.11% and a recall of 41.92%. From the comparison of the three algorithms, the most appropriate for predicting the timeliness of student graduation is the K-nearest neighbor (KNN) algorithm.

Abstract

Kre’ Alang is a traditional woven fabric unique to Sumbawa that holds high cultural and economic value, beauty, and uniqueness, attracting many people. The competition between authentic Kre’ Alang from Sumbawa and similar imitation products that are cheaper poses a threat to the existence of authentic Kre’ Alang. One of the factors causing authentic Kre’ Alang from Sumbawa to struggle against imitation products is the limited marketing media available. UMKM players in Sumbawa still rely on word-of-mouth marketing to promote Kre’ Alang products, which limits their ability to reach a broader market. This has resulted in the original Kre’ Alang from Sumbawa not being able to fully realize its market potential. The e-catalog is a solution that can help reach a wider market. The e-catalog provides complete and detailed information about products to consumers, making it easier to choose and purchase the desired products. Research conducted in 2023 by a team of researchers shows that technology orientation is an important factor in enhancing product competitiveness. Technology orientation refers to the level of use of the latest technology in product marketing. The use of technology such as e-catalogs can help MSME actors like Kre’ Alang to market their products widely, thereby increasing competitiveness and opportunities to reach the market. The method for creating the Kre Alang e-Catalog prototype model uses a flexible prototyping method that is quick and dynamic in its development.

Abstract

Pembelajaran berbasis multimedia saat ini memegang peran penting sebagai sarana komunikasi dalam penyampaian materi yang efektif digunakan tenaga pengajar. Pemanfaatan multimedia bertujuan untuk memberikan pengalaman belajar yang aktif, mendorong kemampuan dalam memecahkan masalah, membangun pengetahuan, serta menggali pengetahuan secara lebih mendalam bagi peserta didik. Peran multimedia tidak hanya sekedar sarana penyampaian informasi, tetapi menciptakan ruang belajar yang aktif dan kreatif.  Pendidikan Sekolah Menengah Pertama Negeri 1 Poto Tano (SMPN) menjalin kolaborasi dengan Fakultas Rekayasa Sistem melaksanakan kegiatan workshop tentang Teknologi Pembelajaran Berbasis Multimedia di Berbagai Platform. Pada kegiatan workshop diikuti oleh guru dan staf tata usaha dengan jumlah 13 peserta. Diharapkan dengan adanya kegiatan ini dapat meningkatkan pengetahuan dan wawasan guru sehingga dapat diimplementasikan.

Abstract

This research aims to design a computerize library information system at SMKN 1 Buer to replace the manual system still used in managing book collections, recording transactions, and generating reports. The existing manual system is deemed inefficient, prone to recording errors, and complicates the process of searching and data recapitulation. The methodology used in this research is a mixed-methods approach, with data collection techniques including interviews and documentation. The system design was carried out using an object-oriented approach with the help of Unified Modelling Language (UML) tools, which include use case diagrams, activity diagrams, class diagrams, and ERD. Admins and members can use the web-based digital library system for login, borrowing, returning, and printing reports, thanks to the design results. This system is expected to improve service efficiency and data accuracy and facilitate users in accessing library information online.
