Abstract

The solar system consists of the Sun as the central star and various other objects within its gravitational influence. Augmented Reality (AR)-based learning is increasingly developing as an innovative educational approach that is more engaging and interactive. With AR technology on the Android operating system, students can understand solar system concepts more visually and dynamically. AR allows users to interact with virtual objects in the real world by combining elements of virtual reality (VR) and the physical environment. In solar system learning, this technology helps students explore three-dimensional (3D) objects more intuitively.Android, as a Linux-based operating system commonly used on portable devices, enables the widespread adoption of AR in education. With a high number of Android users, AR technology has the potential to be an effective solution for enhancing students' understanding of the solar system and other celestial bodies.

Abstract

Taman Wisata Opak terletak di Desa Ringinsari, Bokoharjo, Prambanan, Sleman, Yogyakarta, pada tepian Sungai Opak yang merupakan pertemuan tiga sungai dengan arus tenang. Kawasan ini memiliki potensi lanskap berupa sungai, sawah, dan hutan bambu dengan panorama langsung ke Taman Wisata Ratu Boko. Masyarakat telah berinisiatif mengembangkan kawasan secara swadaya sejak 2018, namun keterbatasan perencanaan membuat pemanfaatan potensi belum optimal. Permasalahan utama adalah ketiadaan arahan pengembangan yang komprehensif dan berkelanjutan. Kegiatan pengabdian masyarakat ini bertujuan membantu masyarakat merancang masterplan kawasan wisata melalui pendekatan co-design, sehingga masyarakat terlibat aktif sejak perencanaan hingga penyusunan rancangan akhir. Hasil pengabdian meliputi dokumen masterplan, denah kawasan, prototipe bangunan berbasis material lokal, serta media promosi berupa video. Pendekatan ini tidak hanya menghasilkan desain fisik, tetapi juga meningkatkan kapasitas masyarakat dalam merawat dan mengelola kawasan wisata berbasis potensi alam dan budaya lokal.
