Abstract
The condition of beaches in Indonesia is currently quite concerning. Indonesia's mangroves and coastal sand are in danger of being damaged. Commitment from all parties is needed to overcome coastal damage. If not, the negative impact will be dangerous for the existence of coastal communities. Damage to coastal is a serious threat to the surrounding ecosystem, even tends to harm humans. Not only waste carried by the flow into the sea, but also garbage disposed of around the coastal areas of the sea and poor land management are clearly some actions that can reduce the carrying capacity of the environment. This carriage a serious threat to the environment. The beach in Subang district, West Java has quite severe coastal damage. Analysis of shoreline changes is needed to overcome the damage to the coast. The method used to analyze shoreline changes is through satellite mapping using Google Earth. The results obtained from 10 years of coastline satellite mapping in Subang Regency are changes in coastline and area that occur due to erosion and/or accretion. These results will help to challenge erosion and/or accretion. The next step can be made a coastal protection in the form of mangrove plants or coastal protection structures.
Highlights
The condition of beaches in Indonesia is currently quite concerning
The conditions around the coastal areas in Indonesia are one of the natural phenomena that have an important role and are closely related to nature and human activities. Natural processes, such as wind, waves, earthquakes and tsunamis occur in Indonesia
The continuous sea level rise identified by global warming can cause the reduction or retreat of the coastline, accelerating theoccurrence of coastal erosion,flooding in coastal areas, and damage toinfrastructure in coastal areas such as piers and other coastal structures [1].The second phenomenonis human activity itself which causes coastal erosion, such as clearing new land bycutting down mangrove forests for the benefit of settlements and infrastructure development [2]
Summary
The condition of beaches in Indonesia is currently quite concerning. Indonesia's mangroves and coastal sand are in danger of being damaged.
