JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) conducted an accuracy test or verification of the maritime radar X-band in the waters of Batu Ampar Port, Batam City, Riau Islands (Kepri).

Head of BMKG Class I Meteorological Station Hang Nadim Batam Ramlan Djambak said the accuracy test was to ensure optimization of the radar's function.

"The team made observations of sea waves to verify maritime radar in Batam," Ramlan said confirmed in Batam, Sunday, which was confiscated by Antara.

He explained that this maritime radar was only built in 2025 in three provinces, one of which was in Riau Islands, namely in Batam.

This maritime radar was built to strengthen early warnings against extreme weather in coastal areas and Indonesian waters. Apart from Batam, Riau Islands, it was also built in Central Kalimantan (Kalteng), and Medan, North Sumatra (North Sumatra).

"The use of this maritime radar is to observe sea waves, currents, winds and sea depths in real time," he said.

Ramlan added that the construction process for the new maritime level will be completed this December, and a function test and verification of maritime data accuracy has been carried out on Saturday (29/11).

"This December (development) has been completed and January is fully operational," he said.

Meanwhile, in a written statement from the central BMKG, it was submitted a maritime radar X-band verification activity in Batam to strengthen the accuracy of marine data.

In the verification activity, the team released a portable buyer wave to measure waves and currents in areas that intersect directly with the X-band radar coverage. This activity is crucial to compare and validate radar-generated wave data and currents.

Director of Maritime Meteorology BMKG Eko Prasetyo explained that this accurate current and wave data will be very useful for shipping activities in the waters around Batam.

Dalam proses verifikasi ini, tim menghadapi tantangan karena kondisi gelombang yang cukup kuat selama dua hari pelaksanaan survei. Meskipun demikian, tim BMKG berhasil menyelesaikan proses verifikasi dengan baik.

This radar network plays a vital role in monitoring maritime conditions in Indonesia's strategic areas.

BMKG hopes that this equipment can function optimally. With the wave and current data submitted more accurately, shipping safety will be more secure for the people of Indonesia.

Eko also invited the community around the location of the placement of equipment to participate in maintaining and maintaining the assets belonging to the BMKG.

"This equipment is very important to produce more accurate weather and early warning data. We need community participation and engagement to maintain BMKG equipment," said Eko.
