Abstract

Background: Mixed Reality (MR) technology enables real-time interaction between physical and digital environments and has become increasingly important in immersive simulation and visualization applications. However, MR implementation still faces challenges related to system performance limitations and the complexity of 3D object rendering, which may reduce immersion quality and interaction realism. Therefore, optimization of 3D assets and visual effects is urgently needed to improve MR efficiency and user experience. Objective: This study aims to propose a design and evaluation framework for Mixed Reality systems by focusing on 3D object optimization and Depth-of-Field (DoF) enhancement in Mixed Reality Simulator (MRSi) development. Methods: The proposed framework integrates vertex decimation-based 3D object optimization and DoF analysis using Circle of Confusion (CoC) calculations. Low-poly 3D assets were optimized through vertex and triangle reduction, while DoF parameters were adjusted based on focal length, aperture, and object distance. Results: The results showed that the proposed approach successfully reduced 3D model complexity by 16.280%–90.950% while maintaining visual quality, with CoC values ranging from 0.0066 to 0.2414, indicating improved depth perception and more realistic visual focus effects in MR environments. The optimization process improved rendering efficiency and enhanced visual realism in Mixed Reality environments. Conclusion: The proposed framework effectively improves MR system performance and immersion quality, providing practical guidance for the development of efficient and visually realistic Mixed Reality applications.

Abstract

This entrepreneurship-based community service program focuses on the cultivation and commercialization of Litopenaeus vannamei shrimp in coastal areas. The implementation method begins with the stocking of vannamei shrimp postlarvae for grow-out, followed by regular monitoring of growth performance through periodic shrimp sampling. Once the shrimp reach marketable size, the harvesting process is conducted. The harvested shrimp are subsequently processed and properly packaged and branded under the name “Khairun Shrimp” to enhance product value and competitiveness. Marketing strategies are implemented through sales at several exhibitions, which aim not only to market the product but also to increase brand visibility. The peak of the promotional activities was participation in an exhibition attended directly by the Minister of Education, Culture, Research, and Technology and the Rector of Khairun University (Unkhair). The success of this exhibition provided significant impacts, including product validation, increased consumer trust, and expansion of marketing networks. Overall, this program successfully demonstrates a sustainable entrepreneurship model that integrates production, packaging, branding, and marketing aspects, serving as a potential reference for the development of micro-enterprises in the marine and fisheries sector.
