R Abdoel Djamali

Abstract


Coastal setback is the land along the shore edge with proportional width to the shape and physical condition of the shore minimally one hundred (100) meters from the highest tide landward. This case study investigated the sand exploitation along the coastal setbacks from Merauke District to Naukenjerai District to supply more than 90% of the material need for the constructions of infrastructure, housing, buildings, offices in Merauke Regency. Sand exploitation activities occurred more than 20 years have damaged infrastructure along the coast and coastal ecosystems, especially mangrove habitats which have functions one of which is as a natural shield from the onslaught of the sea waves where the population in Merauke District reaching 95,410 people (44.78%) of the total population of Merauke Regency is concentrated in the coastal regions. This condition is very dangerous to health, security and safety of the residents in the regions with the hazards caused by environmental damages due to illegal sand excavation. This study mainly aimed to develop a rescue model of coastal setbacks from illegal sand exploitation. The reseach used methodologies, among others: (a) selection of location which included Merauke District and Naukenjerai District by purposive sampling approach, (b) data collection techniques using Focus Group Discussion (FGD) approach and in-depth interviews, (c) data analysis technique by Analysis Hierarchy Process (AHP). This study concluded that: (a) Supervision unit of coastal setbacks is the major priority of the local indigenous ethnic groups, (b) The set of law needed as the priority is Village Regulation, (c) Solution for sand need fulfillment is prioritized to be relocated to Okaba District and Malid District.
