Abstract

Abstract: Both hardware and software technologies offer their advantages in helping to facili- tate student learning activities. Virtual reality technology allows users to interact directly with  the virtual reality environment, giving the effect of a pleasant learning sensation because it pro- vides direct experience for students to actively do desktop computer assembly practicum inde- pendently and guided. This research is R & D (Research and Development), which aims to pro- duce a product as a desktop computer assembly virtual reality learning application. This re- search procedure adapts the Lee & Owens development model. The subjects of this research  were students at the Open University, Makassar State University, and Lambung Mangkurat  University. The results showed that using Virtual Reality in desktop computer assembly can  provide extraordinary experiences to users, bridging the gap between the real and virtual worlds.  This is achieved through specially designed hardware to create a virtual environment that re- sembles the actual reality or even creates an entirely new reality.  Keywords: desktop computer; assembly; virtual reality     Abstrak: Teknologi perangkat keras (hardware) maupun lunak (software) menawarkan  keunggulannya dalam membantu memfasilitasi aktivitas belajar dan pembelajaran ma- hasiswa. Teknologi virtual reality memiliki kemampuan bagi penggunanya untuk dapat  melakukan interaksi langsung dengan lingkungan realitas maya, memberi efek sensasi  pembelajaran yang menyenangkan karena memberikan pengalaman langsung bagi ma- hasiswa untuk aktif melakukan pratikum perakitan computer desktop secara mandiri  maupun terbimbing. Penelitian ini adalah R & D (Research and Development) yang ber- tujuan untuk menghasilkan suatu produk yaitu berupa aplikasi pembelajaran virtual real- ity perakitan computer desktop. Prosedur penelitian ini mengadaptasi model pengem- bangan Lee & Owens. Subjek penelitian ini adalah mahasiswa pada Universitas Ter- buka,  Universitas  Negeri  Makassar,  dan  Unibversitas  Lambung  Mangkurat.  Hasil  penelitian diperoleh bahwa penggunaan Virtual Reality dalam perakitan computer desk- top mampu memberikan pengalaman luar biasa kepada pengguna, menjembatani jurang  antara dunia nyata dan dunia maya. Hal ini dicapai melalui penggunaan perangkat keras  yang dirancang khusus untuk menciptakan lingkungan virtual yang menyerupai realitas  sebenarnya atau bahkan menciptakan realitas yang sama sekali baru. Kata kunci: computer desktop; perakitan; virtual reality

Abstract

Gadget addiction among elementary school-aged children has become a serious concern, especially with the increasing screen time that potentially disrupts learning focus, social interaction, and emotional development. Despite various efforts to control gadget usage, many schools and parents struggle to monitor and predict addiction trends effectively. This gap highlights the need for a structured approach to analyze and predict the spread of gadget addiction. Therefore, this study aims to model the dynamics of gadget addiction using the SEIRS (Susceptible-Exposed-Infected-Recovered-Susceptible) mathematical model. Data were collected through questionnaires to categorize individuals into susceptible (S), exposed (E), addicted (I), and recovered (R) groups. The model was numerically solved using the 5th-order Runge-Kutta method in MATLAB. Simulation results show a decrease in the susceptible group over time, an initial increase and eventual decline in exposed and addicted individuals, and a steady increase in the recovered group, with possible relapse into susceptibility. The analysis reveals that gadget addiction is likely to persist when the basic reproduction number exceeds a critical threshold, signifying the potential for long-term behavioral entrenchment. Sensitivity analysis indicates that the dynamics of gadget addiction are strongly influenced by the rate of peer interaction and the speed at which exposure leads to addiction, whereas higher recovery rates play a significant role in reducing its prevalence. The numerical analysis contributes by offering a reliable and accurate method for simulating real-world addiction patterns. This model provides a quantitative basis for designing more effective intervention strategies. However, this study is limited by the absence of real-time observational data and relies on parameter estimation from survey-based responses.

Abstract

This study aims to develop Batak culture-based domino card learning media to enhance students’ interest and academic achievement in three challenging mathematics topics: trigonometry, integer operations, and logarithms. The research explores how local cultural values, specifically the Batak kinship philosophy Dalihan Na Tolu, can be meaningfully integrated into mathematics instruction. Employing a design-based research (DBR) approach, the study was conducted in seven schools across North Sumatra Province, Indonesia. The development process encompassed media design, expert validation, classroom implementation, and iterative refinement. Instruments utilized included teacher interviews, classroom observations, student questionnaires, and achievement tests. The findings indicate that integrating Dalihan Na Tolu values into game- based learning media provides culturally resonant analogies that enhance students’ understanding of abstract mathematical concepts. In trigonometry, visual and cultural representations helped students distinguish among triangle elements and apply ratio concepts in problem-solving. In the context of integer operations, the domino gameplay facilitated students’ comprehension of signed numbers through contextual scenarios such as altitude and temperature changes. For logarithms, visual simulations and matching exercises supported students in grasping the inverse relationship between exponents and logarithmic expressions. The application of culturally contextualized game-based media not only improved students’ comprehension across all three mathematical topics but also significantly increased their engagement and interest in learning. These findings suggest that incorporating local cultural values into instructional tools can offer an innovative and effective model for advancing mathematics education, particularly in culturally diverse contexts.
