In October 2024, a survey of Reference Points (RPs) located in the Malacca Strait was conducted to determine the condition of these points after being built more than 20 years ago. The RPs surveyed are reference points that play a role in determining the boundaries of the Exclusive Economic Zone (EEZ) in the Malacca Strait. The RP needs to be surveyed because it is used as a reference in determining the position of the Base Point (BP). If the RP is shifted or damaged, then reconstructing the BP position becomes much more difficult.
There were 3 RPs measured, namely RP.181 in Tanjung Jamboaye, RP.182 in Ujung Pereulak, and RP.183 in Ujung Tamiang. These three points were measured by making static Global Navigation Satellite System (GNSS) observations for 1-2 hours referenced to the nearest Continuous Operation Reference Station (CORS).

From this survey activity, information was obtained that there had been a relocating and rebuilding of points at RP.183 and RP.182 in 2023. The relocation of this point caused a shift in the position by 67 metres for RP.182 and 156 metres for RP.183 when compared to the previous point position. In RP.181, there was no relocation and rebuilding of reference points, but there was still a shift of 0.5 metres, which could be caused by deformation of the earth’s surface or differences in measurement methods.

In addition, a discussion was held with the people living along the Malacca Strait. The discussion addressed the issue of the Malacca Strait EEZ boundary and its impact on their daily lives. This discussion was conducted with the Head of Bagan Kuala Village and Sea Tuntong Conservation Activists in Pusung Village, Seruway Sub-district.
