Causes of Coastal Erosion and Environmental Damage on the Sowan Beach of Tuban District

Abstract

Beaches in Tuban district consist mainly of rocky, sandy, muddy, and biogenic beaches (mangroves and corals) with a beach length of 65 km. Factors that cause coastal erosion and environmental degradation in coastal areas are due to natural and human activities. Management policies that ignore the degradation of the coastal environment will result in misleading policies. The purpose of this study is to identify the causes of erosion and damage to the environment of Sowan beach which is a coastal tourist attraction in Tuban Regency. Coastal vulnerability assessment was done by using scoring on seven parameters of human activities. Primary data to determine population activities that influence erosion and damage to the coastal environment was done by distributing questionnaires randomly to 100 communities around Sowan Beach. Based on the results of the Sowan beach vulnerability scoring because human activities indicate conditions that are very vulnerable, a strategy is needed to reduce human activities that are detrimental to Sowan's coastal environment. the results of the vulnerability score of Sowan Beach caused by human activities indicate that conditions are very vulnerable, so a strategy is needed to reduce human activities that are detrimental to Sowan's coastal environment. The results of the vulnerability score of Sowan beach caused by human activities indicate that conditions are very vulnerable, so a strategy is needed to reduce human activities that are detrimental to Sowan's coastal environment. Based on community perceptions, there are 4 destructive human activities; the absence of coastal protection (30%), the presence of wild sand mining (35%), tourism activities themselves (20%) and capture fisheries activities (15%).
