Abstract

The coastal hydrodynamic pattern around the estuary is determined by the wave, river discharge, and the tidal condition which work simultaneously. The wave factor contributes to more dominant influence on estuaries located in the open sea. Wave coming towards the coast can generate current on the coast. The current pattern around the estuary is determined mainly by the magnitude of the angle formed between the incoming wave and the coastline. The objective of this research is to analyze the wave diffraction patterns and the length of tidal propagation towards the direction of the coast in the estuary. Investigated area is situated in the estuary of Jeneberang River. The analysis of tidal propagation and wave diffraction covers a reach of 4270 meters upstream. Data collected include bathymetric, wind, and tidal data. Furthermore, the result of this analysis can be used as an input in efforts to manage and develop the coastal area in the estuary of Jeneberang River. The length of the tidal propagation in the estuary of Jeneberang River is approximately 1220 meters upstream. Wave diffraction occurs from the north, northwest, and west direction. The highest wave diffraction came from the west direction with the value of 0.73 m and the lowest wave diffraction came from the north direction with the value of 0.04 m.

Abstract

Coastal community education is needed to maintain the balance of coastal border areas. The purpose of this activity is to increase public awareness in dealing with and reducing disaster risk and provide a basic understanding of disaster mitigation in coastal border areas. Disaster mitigation is an activity to reduce the impact of disasters. The main components that need to be considered in understanding disasters are hazard, vulnerability, resilience, and risk. An understanding of the four main components will determine how the approach and action to disaster must be taken. The data collection method was carried out by observing the coastal border area in the Takalar area, then conducting a review of data or documents related to the border area and discussions with the community who live around the coastal border in North Galesong District to complete the results of the data review. In this service activity, counseling is carried out, one of which describes the level of danger of abrasion and the efforts made to reduce the risk. The step taken as an effort to reduce the risk of abrasion is to carry out disaster mitigation efforts. Implementation of disaster mitigation counseling in coastal border areas is a form of non-structural disaster mitigation in terms of strengthening community capacity. This outreach activity motivates the community to strengthen capacity and protect the environment around the coastal border, especially to prevent abrasion.
