Port Infrastructure Construction 70 Percent Problem

Nearly 70 percent of coastal port infrastructure and buildings in Indonesia problematic, because the planning and design standards coastal construction. Akibatny, operational costs are very wasteful, unsustainable and easily damaged.

Though nearly 60 percent of cities in Indonesia are in coastal areas, said Head of Coastal Dynamics Assessment (BPDP), Rahman Hidayat, Thursday (19/04/2012). The number of port docks, buildings and coastal shore protection structures are not appropriate due to the design standards kontrusksi that do not adjust to local conditions and the coast of the limited design skills.

"Very few designers of buildings and infrastructure on the coast of Indonesia that equip themselves with knowledge about the condition of the beach morphology along with its properties," said Rahman. He hoped that similar things do not happen on airport development plans in the southern coastal province. Rahman suggested the government would conduct a study testing the physical and numerical models to anticipate the possibility of earthquake and tsunami. Because the southern coast of DIY including the threat of tsunami prone areas. In addition, the level of abrasion due to high waves are also very large and occur almost throughout the year.

"We hope the government would review the DIY plans to build the airport near the southern coast of Java. If you still run, I think we need an in-depth study of the physical conditions and contours of the southern islands of Java and I think needs to be built and tsunami protection breakwater," says Rhman.

While other researchers BPDP, Widjo chat, said the southern coast of Java is prone to earthquakes and tsunami threats. Although rare in southern Java earthquake because the relative age of a very old plate, which is 150 million years, compared to the Sumatran plate average of 60 million years old. "But in the southern Java tsunami was unique, but the slow earthquake can cause a large tsunami because of sediment deposition with a thickness of over 60 meters above the plate. In the event of dislocation of the impact of the tsunami plate three times larger than the area without sendimentasi," said Widjo chat.
