Abstract

Pantai Glagah-Congot, berlokasi di sekitar Yogyakarta International Airport (YIA), mengalami tantangan serius akibat sedimentasi dan erosi yang dipengaruhi oleh longshore current di pantai selatan yang cukup besar. Untuk mengatasi permasalahan ini, pemerintah setempat merencanakan pembangunan groin sebagai bentuk pengamanan pantai. Penelitian ini bertujuan untuk mengevaluasi efektifitas pembangunan groin dalam mengelola sedimentasi dan perubahan morfologi pantai melalui beberapa skenario. Hasil analisis menunjukkan bahwa laju sedimentasi dominan mengarah ke barat dengan nilai 210,074.85 m³/tahun pada kondisi eksisting, sementara skenario 1, 2, dan 3 masing-masing menghasilkan laju sedimentasi 215,517.25 m³/tahun, 282,028.26 m³/tahun, dan 213,569.12 m³/tahun di Pantai Glagah-Congot. Skenario 3 terbukti sebagai pilihan paling optimal karena mampu mengurangi volume erosi di Pantai Glagah-Congot sebesar 14.2%, serta mengelola laju sedimentasi di Muara Sungai Bogowonto dan Muara Sungai Serang secara efektif. Penelitian ini penting untuk memberikan wawasan tentang strategi pengelolaan pesisir yang berkelanjutan di daerah yang rentan seperti wilayah sekitar YIA.

Glagah-Congot Beach, located near Yogyakarta International Airport (YIA), faces significant challenges due to sedimentation and erosion influenced by the substantial longshore current along the southern coast. To address these issues, local authorities have planned the construction of groins as a form of coastal protection. This study aims to evaluate the effectiveness of the groin construction in managing sedimentation and coastal morphology changes through several scenarios. The analysis results show that the dominant sedimentation rate directs westward with a value of 210,074.85 m³/year under existing conditions, while scenarios 1, 2, and 3 result in sedimentation rates of 215,517.25 m³/year, 282,028.26 m³/year, and 213,569.12 m³/year, respectively, at Glagah-Congot Beach. Scenario 3 proves to be the most optimal option, as it effectively reduces the erosion volume at Glagah-Congot Beach by 14.2% and manages the sedimentation rates at the mouths of Bogowonto River and Serang River effectively. This research is crucial for providing insights into sustainable coastal management strategies in vulnerable areas like those surrounding YIA.
