Depth perception is a crucial visual ability for humans to judge distance and understand three-dimensional space. However, the brain's distance estimation is not always accurate and is often influenced by external factors such as color. This study aims to examine in depth how orange color influences the acuity of human depth perception. The method applied is a Systematic Literature Review (TLS) by examining 8 research papers from repository data from Google Scholar and ScienceDirect databases ranging from 2007 to 2025. The results show that orange, as part of the warm color spectrum with a long wavelength, significantly creates an advancing color effect that makes objects perceived as closer than cool colors. The main findings reveal that orange provides superior visual acuity in low-light conditions and has a wide stereoscopic disparity range to help the brain map space. In conclusion, the color orange functions as an effective additional visual cue in strengthening spatial perception. The implications of this research are highly relevant for the development of Augmented Reality (AR) technology and visual safety design, where the use of orange can minimize distance estimation errors by users

This research concerns the Institutional Management Policy of the Medan Area University Library Repository.The purpose of this research is to find out how the institutional management policy of the repository in the Medan Area University library. This research is a descriptive study using a qualitative approach, datacollection techniques with observation, interviews and documentation. The results of this study indicate that the background of the Institutional Repository in the Medan Area University Library is an effort to optimize library tasks in collecting, storing, managing, organizing, preserving, and distributing scientific work information, especially within the Medan Area University academic community. The institutional goal of the repository for the Medan Area University library is to collect (collect), manage, preserve, and open access (distribute) all intellectual works produced by the UMA academic community, both students, lecturers, and staff. The institutional management strategy for the Medan Area University library repository all librarians and employees at the Medan Area University library are involved in repository management, because little or not all human resources (HR) are involved, the library also carries out promotions by conducting outreach to students and also promotion through social media such as ig and fb, building library repositories using hardware (hardware) such as computers and software (software) made by outside developers, preserving library collections Medan Area University library providing external hard drives from CDs that have been given by students to the library then copied to an external hard drive.
