Abstract

Astrotourism is a form of ecotourism that utilizes the quality and beauty of the night sky as its main attraction. The development of astrotourism in Indonesia requires an integrated approach that considers astronomical, meteorological, and tourism aspects. This study aims to develop a site selection model for astrotourism called Holistic Astrotourism Potential (HAP) which is built using the Analytic Hierarchy Process (AHP) method and to implement it in the Danau Ranau area as a case study. A total of 13 parameters were employed, including night sky brightness, observation field of view, cloud cover, thermal comfort, accessibility, and tourism facilities. Parameter weights were determined based on expert judgments from astronomy, meteorology, and tourism fields. The proposed model was applied to six sampling locations around Danau Ranau using field observations, astronomical measurements, and meteorological data. The results indicate that Pantai Bidadari has the highest astrotourism potential among the evaluated sites, supported by favorable night sky quality and clear visibility of the Milky Way. The developed model is expected to serve as a reference for sustainable astrotourism planning and development in Indonesia.

Abstract

Low-cost and locally fabricated robotic telescope systems are increasingly important for education, amateur astronomy, and basic scientific observation. This paper presents the characterization of the UTOPIA-Scope, a do-it-yourself (DIY) alt-azimuth robotic telescope mount developed using extruded aluminum structures and 3D-printed strain-wave gears. The performance of the mount was evaluated through pointing and tracking tests using an alt-azimuth grid and selected equatorial stars. Image center coordinates were obtained using plate-solving techniques and analyzed with descriptive statistical methods. The results show average pointing errors of 1.600° ± 0.123° in azimuth, 0.415° ± 0.048° in altitude, and 0.451° ± 0.106° in equatorial pointing, corresponding to approximately 96′, 25′, and 27′, respectively. Tracking tests indicate drift rates of 22–36 arcsec per minute, depending on the observed sky region. These results provide a quantitative baseline for the performance of the UTOPIA-Scope mount and serve as a reference for further mechanical and control-system improvements toward future scientific applications.
