Abstract

Pantai di Desa Parangtritis, Yogyakarta termasuk dalam prioritas pengembangan pariwisata daerah berdasarkan Peraturan Daerah DIY Nomor 1 tahun 2019 dengan jumlah wisatawan yang mencapai 2,8 juta orang pada tahun 2019. Di sisi lain, data dari BPBD Kabupaten Bantul dan SAR Satlinmas Wilayah III Parangtritis tahun 2009-2015 menunjukkan tingginya jumlah korban arus retas. Oleh karena itu, perlu adanya suatu upaya identifikasi dan penyampaian informasi kepada wisatawan terkait dengan keberadaan arus retas di pantai-pantai yang ada di Desa Parangtritis. Identifikasi keberadaan arus retas dilakukan pada dua waktu yang berbeda, yaitu pada musim timur dan musim barat, dengan melakukan interpretasi visual melalui citra satelit dan memperhatikan keberadaan gisik tanduk maupun zona pecah gelombang yang terpotong. Hal tersebut dikarenakan morfologi pantai dapat berubah sebagai respon dari musim yang berdampak pada aktivitas gelombang, arus, dan pasang surut yang berbeda pula. Penelitian ini bertujuan untuk menganalisis morfologi, morfometri, dan morfoaransemen untuk menemukenali keberadaan, tipe, sirkulasi, dan bahaya arus retas di Pantai Parangtritis. Kemunculan 11 lokasi arus retas pada saat bulan Agustus/musim timur lebih tersebar secara merata di sepanjang pantai di Desa Parangtritis dibandingkan dengan 12 lokasi saat bulan April/musim barat. Arus retas di Desa Parangtritis sangat dinamis sehingga perlu adanya upaya diseminasi informasi bahaya arus retas pada wisatawan dan pelaku wisata sebagai salah satu tindakan mitigasi dan pengurangan risiko bencana di Desa Parangtritis.
