SEMARANG - Coordinating Minister for Infrastructure and Regional Development (IPK) Agus Harimurti Yudhoyono (AHY) ensured that flood management in Pantura Java was not limited to concrete or physical approaches.
"We together with the Javanese Pantura Management Authority led by Admiral (Laksdya TNI Retired) Didit are trying to build good collaboration and synergy," he said after giving a public lecture at the Diponegoro University (Undip) campus, Semarang, Thursday. , November 27 reported by ANTARA.
According to him, to perfect the blueprint for the construction of "Giant Sea Wall" does require comprehensive processes and research.
"Because it is a big project, it requires a large budget, and involves many parties. At least 17 ministries and institutions will be involved," he said.
He acknowledged that the floods and the tidal wave of Pantura are currently the concern of President Prabowo Subianto, and the Coordinating Ministry (Kemenko) he leads continues to strive to protect the Pantura Jawa area.
"From Banten, Jakarta, West Java, Central Java to East Java all have vulnerabilities. Indeed, Semarang and Demak are among the highest intensities. Therefore, it is necessary to get even greater support and attention," he said.
However, he said, not everything was later resolved with concrete buildings, such as Giant Sea Wall, but would be combined with various efforts, such as mangrove planting, and so on.
"Don't imagine everything will become concrete. Later there will be the worst parts that can't be used for other solutions, of course we build high concrete. However, others can still use other approaches, Hybrid Sea Wall," he said.
In accordance with the public lecture, he said the discussion of the matter was relevant because Indonesia faced disaster threats and challenges, and Undip was one of the leading campuses that oversees sustainable development.
AHY said there were quite a lot of research results by Undip researchers, and also those that had been applied in the field because Undip was also in the Pantura area which at any time also faced the threat of flood and tidal hazards.
"In principle, we will combine various approaches. So, the construction of coastal embankments, sea embankments, including more natural solutions, such as using mangroves and so on will still be part of an integrated, comprehensive, and more efficient concept," he said.
Meanwhile, Undip Chancellor Prof. Suharnomo provided support for regional infrastructure development measures in the Central Java area, including the Pantura area.
According to him, Undip has also contributed to supporting Central Java's progress through various innovations in the results of campus research., including overcoming the phenomenon of tidal and high sedimentation in the Pantura area of Central Java, by submitting a hybrid sea wall concept.
"This is a sea wave prevention technology that combines the engineering of light concrete structures with the restoration of mangrove ecosystems," he said.
In addition to the construction of embankments, he said, this approach prioritizes the recovery of mangrove ecosystems to slow down wave energy, withstand sediments, and help develop natural land.
