Abstract

Sea turtles are one of the key biota in coastal and marine ecosystems whose existence is not only ecologically important, but also holds social, cultural, and economic value. Indonesia, as the largest archipelagic country in the world, is home to six of the world’s seven sea turtle species, making it a globally significant habitat for the sea turtle life cycle. The Gili Matra Marine Protected Area, encompassing the three islands of Gili Trawangan, Gili Meno, and Gili Air, is one of the strategic regions with high potential for sea turtle conservation. This study aims to document and analyze the spatial distribution and habitat use of green turtles (Chelonia mydas) and hawksbill turtles (Eretmochelys imbricata) in the Gili Matra Marine Protected Area. Data collection was carried out during the period of September to October 2024, adjusted to weather conditions and water visibility. The method used was the Underwater Turtle Visual Census Methodology. The composition of sea turtle species and habitat characteristics were analyzed using descriptive analysis to summarize the patterns of species presence, habitat types, and environmental conditions observed during the survey. The findings indicate that the area supports both species, with sea turtles observed at various depths (9–16 meters) across multiple dive sites. The predominance of female individuals and the variation in species presence across sites suggest species specific habitat preferences and potential influences of environmental conditions. Both sea turtle was mostly observed in locations associated with coral reef structures.

Abstract

Kawasan Konservasi Pulau Gili Matra merupakan kawasan konservasi laut yang memiliki nilai ekologis tinggi sekaligus menjadi destinasi wisata bahari unggulan di Nusa Tenggara Barat. Tingginya aktivitas wisata bahari di kawasan ini menuntut adanya pengelolaan yang berorientasi pada konservasi dan keberlanjutan dengan melibatkan masyarakat lokal sebagai mitra strategis. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kapasitas kelompok masyarakat penyelam dalam mengenali, mendata, dan memetakan satwa laut dilindungi sebagai upaya mendukung konservasi laut berbasis masyarakat. Kegiatan dilaksanakan pada periode Juli–Agustus 2025 dengan pendekatan partisipatif dan pemberdayaan masyarakat. Metode pelaksanaan meliputi tahap sosialisasi, pelatihan teknis identifikasi dan pendataan, penerapan teknologi dan pemetaan sederhana, pendampingan menjadi pemandu wisata konservasi, serta evaluasi kegiatan. Hasil kegiatan menunjukkan adanya peningkatan pemahaman masyarakat penyelam terhadap pentingnya konservasi satwa laut dilindungi, yang ditunjukkan oleh peningkatan nilai pemahaman dari 42% menjadi 85%. Selain itu, peserta mampu memanfaatkan teknologi sederhana untuk pendataan dan pemetaan satwa laut dilindungi, serta sebagian peserta mampu berperan sebagai pemandu wisata konservasi. Kegiatan ini juga menghasilkan pembentukan kelompok kerja Citizen Science sebagai dasar keberlanjutan program. Secara keseluruhan, kegiatan pengabdian ini berhasil memperkuat peran masyarakat penyelam sebagai mitra konservasi dan mendukung pengelolaan kawasan konservasi di Gili Matra secara partisipatif dan berkelanjutan.

Abstract

Coral reefs are coastal ecosystems with high biodiversity that play a crucial role in aquatic productivity and the sustainability of fisheries resources. Nektonic biota are closely linked to coral reef conditions through their roles in trophic structure, energy cycling, and the regulation of ecosystem dynamics. This study aimed to analyze the diversity, abundance, and biomass of reef-associated nektonic indicator species and other reef fishes in the Gili Matra Marine Conservation Area, West Nusa Tenggara, Indonesia. Data were collected from March to June 2024 using the Underwater Visual Census (UVC) method along 70 m belt transects
