Abstract

Presentation of information for educational institutions is one of the most important means to introduce the institutions to the public. Raudhatul Athfal (RA) Ar-Rasyid Tanjungpinang needs media that can promote and provide information about the institution, because the number of registrants is decreasing during current years. This research was conducted with the creation of the institution’s profile video that applies elements of live shoot and motion graphics to easily convey information in short duration videos, and to make the profile video look interesting. The stage of making a profile video is starting from taking pictures directly (live shoot), editing to rendering process. Based on the process of designing, implementation, testing and discussion, it can be concluded that this research has been able to produce a profile video that can be used as a promotional mean for attracting new students in 2017/2018 at RA Ar-Rasyid Tanjungpinang. The result shows that 77% of 98 applicants have been informed through video profiles distributed with Videotron.

Abstract

This study investigates the performance impact of 3D assets in a virtual reality (VR) simulation designed for climate change education, aiming to balance visual fidelity and system efficiency on standalone headsets. Using a case study modeled on a sustainable energy environment, key performance metrics frames per second (FPS), triangle count, and draw calls were measured to assess the effect of object density, material transparency, and batching strategies. Experimental results show that configurations with 20 trees and 20 characters maintained 101 FPS, while denser scenes with 30 trees and 30 characters dropped to 79 FPS approaching the minimum usability threshold for VR. Transparent tree foliage with alpha-cutout materials imposed higher graphics processing unit (GPU) loads than high-triangle opaque character models, highlighting the performance cost of material complexity. These findings offer practical guidelines for optimizing asset configurations in immersive educational VR content. Future work may explore integration of artificial intelligence (AI) behavior and user interaction to assess broader system performance.

Abstract

Mobile Augmented Reality has expanded including the cultural heritage sector. Among the options offered is the digitization of cultural heritage. Multiple technical breakthroughs has implemented, including hand gesture recognition and body tracking, into mobile augmented reality systems. The success of these improvements depends on a good user interface. Meta User Interface (Meta-UI) allows significant information to be displayed without interfering with system operation. The results of the analyses that the Meta-UI user interface could aid users in employing hand gestures and body motion capture on this mobile augmented reality without any issues and could deliver information about batik efficiently. PIECES Framework testing confirmed this, with a satisfaction score of 4.40 to 4.55. Using the PIECES Framework concepts and questionnaire that focus on user satisfaction with mobile augmented reality, the score indicates that the user is satisfied.
