Abstract

Whale shark (Rhincodon typus) is the largest fish species in the world and is classified as endangered. This study is crucial for the conservation of this species and developing effective conservation strategies. The research was conducted in the Botubarani waters, Gorontalo Province. Individual whale shark identification was performed using Photo ID, including the identification of sex and wound location. Photo IDs were processed using the Interactive Individual Identification System (I3S) software and includes information related to the ID, body length, and the time the individual was previously identified. Monitoring of the location, number, timing of whale shark presences and water parameters, was carried out through direct field observations. The results showed that 5 whale shark individuals were identified, all of which were male, with lengths ranging from 4.5 to 4.8 meters, and 1 individual had visible wounds. From 78 days of monitoring, Whale sharks were observed for 70 days and not observed for 8 days. The frequency of whale shark appearances ranged from 1 to 4 individuals per day. Whale sharks in Botubarani waters exhibited site fidelity and a mixed migration pattern. The intensity of their presence is quite high. This intensity is supported by ecological conditions that are optimal for the life of whale sharks, particularly those of juvenile age. The measured water parameters significantly influence their presence.

Abstract

Potensi wisata di Provinsi Banten yang menarik minat wisatawan diantaranya adalah pada wisata bahari (Pantai Anyer, Tanjung Lesung, Pantai Sawarna, Pulau Peucang, dan Pulau Burung). Penelitian ini bertujuan untuk mengetahui Daya Dukung Kawasan (DDK), Indeks Kesesuaian Wisata (IKW) ekowisata bahari dan untuk menganalisis potensinya di Provinsi Banten. Penelitian ini dilakukan di 4 Kabupaten dan 1 kota, dengan 11 lokasi objek wisata yang dijadikan sampel. DDK di 11 lokasi pantai tertinggi yaitu 180 orang/50 m2 panjang pantai yaitu di Pantai Sawarna (Lebak), di Pantai Pulau dua (Serang) dengan DDK 20 orang/50 m2 per hari. DDK wisata mangrove didapat dari dua lokasi yaitu PRPM Kronjo (Tangerang) dengan 72 orang/50 m2 dan Cagar Alam Pulau Dua (Serang) dengan 32 orang/50 m2  per hari. Sedangkan untuk DDK wisata snorkeling yang tertinggi yaitu; Spot Ciapus 8 orang/50 m2, dan terendah di Pulau Badul 3 orang/50 m2 per hari. Pantai Pulau Peucang (Uj. Kulon) memiliki nilai IKW tertinggi yaitu 96.67% dan yang terendah di Pantai Pulau Cangkir (Tangerang) yaitu 55.6%, Kategori rekreasi mangrove terdapat di dua lokasi yaitu; ekowisata mangrove PRPM Kronjo dengan nilai IKW 55.55% dan ekowisata mangrove Cagar Alam Pulau Dua dengan nilai IKW tertinggi 81.25%. Kategori rekreasi snorkeling tertinggi yaitu; Spot Legon Sumino dengan Nilai IKW 91.23% dan terendah di Pulau Badul dengan Nilai IKW 80.7%.
