Abstract
Pantai merupakan kawasan peralihan atau batas antara daratan dan perairan yang memiliki sifat dinamis. Garis pantai memiliki peran terhadap wilayah administrasi, penentuan batas maritim, penentuan kewenangan pengelolaan sumber daya laut provinsi, serta penataan ruang wilayah (darat dan perairan, termasuk pesisir). Sungai Porong yang terletak di perbatasan Kabupaten Sidoarjo dan Kabupaten Pasuruan, memiliki aktivitas di pesisir laut yang banyak, seperti pertambakan, permukiman, hingga pariwisata. Adanya pembuangan lumpur di Sungai Porong mempengaruhi dinamika garis pantai, khususnya muara sungai Porong. Melalui penelitian ini, analisis dilakukan dengan menggunakan penginderaan jauh dan Digital Shoreline Analysis System (DSAS) untuk memperoleh nilai perubahan (dinamika) di pesisir Sidoarjo – Pasuruan. Penggunaan rentang data 4 – 8 bulan diperoleh nilai rata-rata tertinggi (rata-rata akresi tertinggi) sebesar 32,685 meter dan nilai rata-rata terendah (rata-rata abrasi tertinggi) sebesar -34.116 meter. Pada penggunaan rentang data 1 tahun diperoleh nilai rata-rata tertinggi (rata-rata akresi tertinggi) sebesar 21,664 meter. Tren dinamika garis pantai dengan menggunakan rentang data yang lebih sempit menunjukkan dinamika garis pantai yang lebih detail dan bervariatif. Penggunaan data dengan rentang besar, efektif untuk perhitungan perubahan garis pantai dengan kurun waktu yang panjang. Prediksi garis pantai ke depan diperoleh dengan menggunakan data garis pantai yang telah dihasilkan. Validasi dilakukan dengan menggunakan data drone, yang menghasilkan perhitungan nilai kesalahan geometrik data citra sebesar 2,181 meter dan nilai korelasi vegetasi tinggi.

Beach is a transition area or boundary between land and water that has dynamics properties. Coastlines have a role in administrative areas, determining maritime boundaries, determining the authority to manage provincial marine resources, as well as regional spatial planning (land and water, including coastal areas). The Porong River, which is located on the border of Sidoarjo Regency and Pasuruan Regency, has many activities on the coastal area, such as aquaculture, settlements and tourism. The presence of mud sediment carried in the Porong’s River impacted the coastline dynamics at the river mouth. Through this research, analysis was carried out using remote sensing methods and Digital Shoreline Analysis System (DSAS) to determine the value of changes (dynamics) of coastlines that occur in the Sidoarjo – Pasuruan coastal area. Using a data range of 4 – 8 months, the highest average value (highest accretion average) was 32.685 meters and the lowest average value (highest abrasion average) was -34.116 meters. When using 1 year data range, the highest average value (highest accretion average) was obtained at 21.664 meters. Trends in coastline dynamics using a narrower data range show more detailed and varied coastline dynamics. The use of data with a large range is effective for calculating changes in coastlines over long periods of time. Future coastline predictions are obtained using coastline data that has been generated. Validation was carried out using drone data, which resulted in the calculation of a geometric error value for the image data of 2.181 meters and a high vegetation correlation value.
