Abstract
Perubahan garis pantai sangat penting untuk diteliti karena hal tersebut dapat menyebabkan abrasi, akresi, dan banjir rob. Pada daerah sekitar pesisir Suramadu - Wonorejo banyaknya terjadi keluhan kapal-kapal milik nelayan yang dari laut tidak dapat memasuki muara sungai dikarenakan terjadinya pendangkalan. Maka dengan demikian dalam Penelitian ini akan dilakukan untuk memantau perubahan garis pantai pada rentang tahun 2006, 2009, 2012, 2015, 2018, 2021 dan 2023 serta memprediksi perubahan garis pantai 25 tahun kedepan dengan menggunakan Digital Shoreline Analysis System dan One-Line Model. Hasil perubahan garis pantai menggunakan Digital Shoreline Analysis System didapatkan garis pantai mengalami akresi terbesar pada tahun 2009-2012 sebesar 385 meter pada daerah Kecamatan Kalisari Utara Surabaya, selain itu juga terjadi abrasi terbesar pada tahun 2015-2018 pada daerah Tambak sebesar 39 meter. Hasil prediksi perubahan garis pantai menggunakan One-Line Model dengan metode CERC untuk 25 tahun kedepan didapatkan garis pantai akan mengalami kemajuan terbesar pada daerah Pantai Ria Kenjeran sebesar 37 meter dan mengalami kemunduran sebesar 70 meter pada daerah pantai kenjeran lama. garis pantai pada Pesisir Suramadu - Pesisir Wonorejo dapat dicegah dengan adanya konservasi lingkungan, Penanaman mangrove dan Pembangunan infrastruktur Pelindung pantai

Coastline changes are very important to study because they can cause abrasion, accretion and tidal flooding. In the area around the coast of Suramadu - Wonorejo, there are many complaints that fishing boats from the sea cannot enter the river mouth due to silting. Therefore, this research will be carried out to monitor changes in coastlines in the years 2006, 2009, 2012, 2015, 2018, 2021 and 2023 and predict changes in coastlines in the next 25 years using the Digital Shoreline Analysis System and One-Line Model. The results of changes to the coastline using the Digital Shoreline Analysis System showed that the coastline experienced the largest accretion in 2009-2012 at 385 meters in the North Kalisari District area of Surabaya, apart from that, the largest abrasion also occurred in 2015-2018 in the Tambak area at 39 meters. The results of predictions of changes in the coastline using the One-Line Model with the CERC method for the next 25 years show that the coastline will experience the greatest progress in the Ria Kenjeran Beach area by 37 meters and will experience a setback of 70 meters in the Old Kenjeran beach area. The coastline on the Suramadu Coast - Wonorejo Coast can be prevented by environmental conservation, planting mangroves and building coastal protection infrastructure
