PT Hutama Karya (Persero) said the progress of the construction of Coastal Security to protect the coast of Jakarta Bay from the threat of tidal flooding had reached 53.14 percent.

"This National Strategic Project (PSN) is carried out to strengthen and increase sea embankments, river estuary embankments as well as structuring the coastal areas north of Jakarta and its surroundings, with current progress reaching 53.14 percent," said Executive Vice President (EVP) Secretary of Hutama Karya Adjib Al Hakim quoted from the official website of Hutama Karya, Kami, May 16.

Adjib said this project was built as an effort to protect the surrounding area from the threat of tidal flooding, especially in residential areas when sea water was high due to land subsidence and sea level rise.

The construction of Coastal Security on the Jakarta Bay Coast Phase 6 Package 4 which is located in Penjaringan District, North Jakarta and Kosambi District, Tangerang Regency, cost Rp297 billion.

The project, which has been started since December, is targeted for completion by the end of December 2024.

With a total length of 1,485 meters (m), the project is divided into zones A, B and C. The types of work that have been completed with KSO Wika-Hutama Karya, namely in zone A covering the preparation of a concrete pole type D800, cerucuk work and bamboo mattresses and the preparation of a box pole measuring 25 x 25 cm as the foundation for fishing access piers.

Meanwhile, the work remaining today is the work of the sirtu pile in the A zone, CCSP preparation or the W400 type flat concrete sheet embankment in the B zone as well as the work of the W450 CCSP buildup and design in the C zone.

In the construction of the embankment, there is a design in the form of a cone and bamboo mattress that functions to withstand the structure of sirtu piles and boulders. In addition, it is also used inner bore technology where the installation of stake poles is more environmentally friendly because it does not cause air pollution, noise pollution and minimal vibration.

According to Adjib, Hutama Karya is committed to completing this project, both in terms of quality and time, so that later it will be used to withstand sea water due to tidal waves, reduce economic and social losses due to tidal flooding and as a limit to land development in coastal areas or regional arrangement.

"It is hoped that this project will later increase beach resistance to erosion and strengthen coastal infrastructure for the area around Jakarta Bay," he added.
