DEVELOPMENT OF AN AUGMENTED REALITY APPLICATION FOR LEARNING THE VOLUME AND SURFACE AREA OF THREE-DIMENSIONAL SHAPES

Sapta, Andy, Pakpahan, Sondang Purnamasari
Abstract: This study focuses on the development of an Augmented Reality (AR)–based learning application designed to assist students in understanding the mathematical concepts of volume and surface area of three-dimensional geometric… tric shapes. The development process adopted the Multimedia Development Life Cycle (MDLC) model, which consists of six systematic stages: concept, design, material collecting, assembly, testing, and distribution. The research concentrated on the development and expert validation stages. Validation results from content and media experts indicate that the application meets pedagogical and technical feasibility standards. The content expert confirmed that the materials align with the national mathematics curriculum and are presented in a clear, contextual, and accurate manner, while the media expert highlighted the user-friendly interface, interactive features, and visual appeal of the application. Theoretically, this AR-based medium bridges the gap between abstract mathematical concepts and concrete visualization by enabling students to interact directly with virtual 3D objects. Practically, the application enhances learning motivation and engagement by providing dynamic, interactive experiences. Overall, this research contributes to the advancement of educational technology by offering a systematic model for developing AR-based learning media that support active and meaningful learning in the digital era.

AHP - SAW DECISION SUPPORT SYSTEM FOR AI-BASED TEACHING MATERIAL RECOMMENDATION

Amin, Muhammad, Rasyid, Hainur, Akmal, Akmal
Abstract: Abstract: The development of Artificial Intelligence (AI) in education provides significant opportunities for supporting the development of English teaching materials in elementary schools. However, the wide variety of available… vailable AI tools makes it difficult for teachers to select the most appropriate tools for their instructional needs. This study aims to analyze and generate recommendations for AI utilization using a Decision Support System (DSS) based on the Analytical Hierarchy Process (AHP) and Simple Additive Weighting (SAW) methods. The AHP method is used to determine the weight of criteria based on their importance, while the SAW method is applied to rank alternative AI tools. This study involves teachers at SDN 15 Padang Genting in identifying criteria and evaluating alternatives. The results show that the proposed DSS model is capable of generating appropriate AI tool recommendations based on predefined criteria. This approach contributes to more objective and systematic decision-making in utilizing AI for developing English teaching materials in elementary education.

Arman, Yudha, Sari, Renny Puspita, Mutiah, Nurul, Prawira, Dian
Abstract: The laboratory is one of the facilities owned by the FMIPA Laboratory, which is one of the facilities owned by Tanjungpura University to support tridharma activities. There are several problems in laboratory management,… namely that management is carried out manually, so it takes a long time to apply for the loan of laboratory equipment and to prepare a free laboratory loan letter. In order to improve services, ensure data security, and accommodate all laboratory data, it is necessary to develop an FMIPA laboratory information system (SILABMIPA). The FAST framework is used in developing SILABMIPA to suit user needs. The analysis and development of SILABMIPA follows the FAST method with the stages Scope Definition, Problem Analysis, Requirements Analysis, Logical Design, Decision Analysis, Physical Design and Integration, Construction and Testing. With the construction of SILABMIPA, it can make it easier for managers to manage laboratories, assist students in applying for and borrowing equipment, as well as making laboratory loan-free certificates. Based on the results of system functional testing against SILABMIPA, it was found that the system operates well in accordance with the user's functional needs, while the results of system interface testing obtained a percentage of 82.60% in the very good category.

Kova, Stella, Prehanto, Adi, Guntara, Rangga Gelar
Abstract: Abstract: Usability testing of online animal adoption systems is important because it is not only related to the comfort and safety of users, but also to the welfare of the adopted animals. So far, usability testing of the… he animal adoption system on Eidos has not been carried out and there is a problem that there is confusion with the process flow in this animal adoption system. This usability testing uses the Heuristic Evaluation method and the System Usability Scale (SUS), which involves in-depth interviews to obtain results that are not only statistical assessments, but also deeper insights from the user's perspective. The results of the evaluation using Heuristic Evaluation obtained 59 problems, with an average severity rating of 3 or major, whose improvements have resulted in several draft design recommendations. The recommendation design has gone through final testing using the System Usability Scale (SUS) which managed to achieve a score of 78, or categorized as good, along with some minor critical feedback for system improvement. Therefore, users as a whole feel very satisfied in using the online adoption system from the results of the existing recommendation design. The implications of the resulting recommendation design have been tested for usability by three UI/UX design experts and users directly so that they can be used as a basis for developing a better online animal adoption system.             Keywords: animal adoption system; heuristic; prototype; system usability scale; usability     Abstrak: Pengujian usability sistem adopsi hewan secara online penting untuk diperhatikan karena tidak hanya berkaitan dengan kenyamanan dan keamanan penggunanya saja, tetapi juga meningkatkan kesejahteraan hewan yang diadopsi.
