Abstract

Penelitian ini mengkaji perubahan garis pantai selama satu dekade (2014-2023) di wilayah kepesisiran Kabupaten Kulon Progo yang memiliki panjang garis pantai +- 25,5 km. Garis pantai didapatkan dari ekstraksi citra satelit Landsat 8-9 OLI dengan memanfaatkan Band NIR dan SWIR 1 dan 2. Model perubahan garis pantai didapatkan dari pengolahan Digital Shoreline Analysis System (DSAS). Perhitungan model perubahan garis pantai yang dipilih adalah End Point Rate (EPR) dan Linear Regression Rate (LRR). Dari hasil penelitian ditemukan bahwa wilayah kepesisiran Kabupaten Kulon Progo seperti Pantai Congot, Pantai Glagah, Pantai Bidara, Pantai Bugel, dan Pantai Trisik serta Muara Sungai Progo setiap tahunnya mengalami kemunduran pantai yang ditunjukkan dengan nilai EPR dan LRR yang negatif. Erosi marin tertinggi yang terjadi di wilayah Kepesisiran Kabupaten Kulon Progo terdapat di Muara Sungai Progo, dengan  estimasi EPR dan LRR dapat mencapai erosi sejauh 20,4 m/ tahun (EPR) dan 23,1 m/tahun (LRR). Histori erosi marin di wilayah kepesisiran Kabupaten Kulon Progo menyebabkan hilangnya ekonomi dan mata pencaharian. Hasil dari penelitian ini dapat memandu para peneliti dan para pengambil keputusan untuk perencanaan dan pengelolaan wilayah kepesisiran yang berkelanjutan. Kata kunci: Wilayah Kepesisiran, erosi marin, DSAS, EPR, LRR DOI: http://dx.doi.org/10.23960/jpg.v12.i1.28562

Abstract

This study explores the relationship between snorkelers perceptions of service quality by snorkeling guide. This study investigated the essential safety skills and knowledge of snorkeling guide in the Karimunjawa Islands, a popular marine tourism destination within Indonesia’s exotic Coral Triangle. Ensuring proper safety standards in critical for minimizing risk and enhanching the destination’s appeal. To understand the guides role in delivering safe, comfortable, and memorable experiences. The study employed a qualitative methodology, data was gathered through interviews with tourist, guide and the Indonesian Tourist Association management. Complimented by field observations to document activities and validate information. The key findings reveal that guides are highly effective at providing informative briefings, supervising tourist, and possess relevant training in water rescue and guide competency. The study concludes that investing in guide skills is a proven strategy for improving tourist safety and preventing future water accidents, recommending ongoing training updates.

Abstract

A tsunami disaster threatens Ende City. Ende City's coastal area management policy regarding disaster mitigation must consider coastal typology. Efforts to reduce the risk of tsunamis must pay attention to the physical development of coastal land to maintain the coastal resources. Therefore, this research aimed to analyze the level of tsunami susceptibility based on coastal typology in the coastal area of Ende City. The methods used in this research are survey and spatial analysis. The survey results were compared with literature studies to determine coastal typology and land use. Spatial analysis uses overlay, scoring, and weighting techniques to produce tsunami susceptibility levels. Geospatial parameters that determine the level of susceptibility are topography, distance from the coastline, slope, distance from rivers, and coastal morphology. Susceptibility analysis is carried out for each coastal typology because each has a different response to tsunami. The research results show five classes of tsunami susceptibility: very susceptibility, susceptibility, somewhat susceptibility, safe, and very safe. Very susceptible areas are marine deposition coast typology, anthropogenic coast typology, and sub-area deposition coast typology. The secure areas are wave erosion coast typology and volcanic coast typology.Keywords: Coastal City of Ende, Coastal Typology, Tsunami, Susceptibility, Land Use.
