Abstract

This research aims to develop a Computer Adaptive Test (CAT) system using the Items Response Theory (IRT) approach. This study is part of developing a web-based system using the Research and Development (R&D) method, employing the Four-D (4-D) model. At its core, this system is similar to a Computer-Based Test (CBT). Still, the critical difference lies in its ability to randomize and provide questions that align with the test-taker's skill levels using the Items Response Theory (IRT) algorithm. The system employs the 3-PL model from the Items Response Theory, considering the difficulty level of questions, the discriminative power of questions, and the likelihood of guessing or interference in the questions. The examination system randomly assigns questions to students based on their responses to previous questions, ensuring that each test-taker receives a unique question sequence. The exam concludes when a test-taker accurately estimates their ability, i.e., SE <= 0.01, or when all questions have been answered. The outcome of this research is a Computer Adaptive Test (CAT) system based on the Items Response Theory (IRT), which can be used to assess students' learning outcomes. This research was implemented in the Multimedia Department of SMK Negeri 1 Gunung Talang, with 90 students as the research sample. The evaluation of the practicality of this system received very high scores, indicating that the Computer Adaptive Test (CAT) system based on the Items Response Theory (IRT) is considered highly practical and effective in achieving the established measurement goals.

Abstract

This research is motivated by the need for the media to learn that promote interaction and understanding of learning. The purpose of this research was: 1) to produce interactive learning media on Basic Graphic Design subjects at vocational high school. 2) Determining the validity of interactive learning media on Basic Graphic Design subjects at vocational high school. The method used is a Research and Development (R & D). The development Model used is 4-D (Four-D). The 4-D consists of four stages, namely discovering, designing, developing and disseminating. The subjects of research conducted were material experts and media experts. The instrument used to measure the form of validity is the questionnaire responses. The validity of interactive learning media is assessed from two aspects namely media feasibility and feasibility aspects of the matter. The results of this research indicate that interactive learning media on Basic Graphic Design subjects is considered valid as seen from the average value of media validation by 0.87 and the average result of 0.85 material validation. Based on the results of the validation of the interactive learning media on Basic Graphic Design subjects are feasible for use in assisting the learning process.

Abstract

Proses pemesanan digital printing pada CV. Anugrah Murni Sejati masih menghadapi kendala karena komunikasi pesanan dilakukan melalui pesan instan, informasi spesifikasi produk belum terstandarisasi, pencatatan transaksi belum terintegrasi, dan verifikasi pembayaran masih manual. Kondisi tersebut ditunjukkan oleh data operasional 2024–2025, ketika rata-rata waktu konfirmasi meningkat dari 2,1 jam menjadi 5,5 jam dan tingkat revisi produk naik dari 18% menjadi 44%. Penelitian ini bertujuan merancang dan membangun sistem informasi pemesanan digital printing berbasis web dengan metode Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) untuk memberikan rekomendasi spesifikasi produk secara objektif. Penelitian menggunakan metode pengembangan prototyping melalui tahap communication, quick plan, modeling quick design, construction of prototype, serta deployment, delivery, and feedback. Sistem dikembangkan dengan Laravel, PHP, MySQL, dan integrasi payment gateway Midtrans. Hasil perhitungan TOPSIS pada alternatif banner menunjukkan Banner Flexi Korea 440gsm sebagai rekomendasi terbaik dengan nilai closeness coefficient 0,631. Pengujian black box menunjukkan seluruh modul utama, meliputi autentikasi, katalog, pemilihan spesifikasi, rekomendasi TOPSIS, pemesanan, pembayaran, dan riwayat transaksi, berjalan sesuai skenario. Sistem yang dibangun meningkatkan keteraturan alur pemesanan, mempercepat konfirmasi transaksi, dan membantu pelanggan memilih spesifikasi produk secara lebih tepat The ordering process at CV. Anugrah Murni Sejati still faces operational problems because orders are handled through instant messaging, product specification information is not standardized, transaction records are not integrated, and payment verification is performed manually. Company operational data from 2024 to 2025 indicate that the average confirmation time increased from 2.1 hours to 5.5 hours, while the product revision rate rose from 18% to 44%. This study aims to design and develop a web-based digital printing ordering information system using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method to provide objective product specification recommendations. The system was developed using the prototyping model, consisting of communication, quick planning, modeling quick design, prototype construction, and deployment, delivery, and feedback. The application was implemented with Laravel, PHP, MySQL, and Midtrans payment gateway integration. The TOPSIS calculation for banner alternatives identified Banner Flexi Korea 440gsm as the best recommendation with a closeness coefficient of 0.631. Black box testing showed that all major modules, including authentication, catalog, specification selection, TOPSIS recommendation, ordering, payment, and transaction history, operated according to the expected scenarios. The developed system improves ordering structure, accelerates transaction confirmation, and supports customers in selecting more appropriate product specifications.
