The East Coast Economic Region (ECER) was established in 2007 with the announcement of the ECER Master Plan by the Malaysian Government. Meanwhile, the ECER Development Council (ECERDC) is driving development in the ECER by launching several high-impact projects and programmes to promote socioeconomic transformation by increasing private investment in the region. The ultimate goal is to close the socioeconomic gap between East and West Coasts by empowering local communities to benefit from job and entrepreneurial opportunities. One of the ECER projects is the construction of the Palekbang Bridge in Kelantan, which will connect Kota Bharu and Palekbang, Tumpat. The bridge construction is critical in light of two factors: Congestion at the Sultan Yahya Petra Bridge and limited growth in the Kota Bharu city centre. This paper discusses the role of ECERDC as the primary monitoring body for the project, as well as the potential of the Palekbang Bridge to provide physical, economic, and social benefits to citizens. It is hoped that the bridge construction will address congestion and limited growth, stimulate trade activities, improve connectivity, and accessibility. As a result, economic growth across all economic sectors will be boosted in the coming years.

Spatial Distribution of Total 210Pb in the Marine Sediment of Peninsular Malaysia: Radioactivity Level Variations in the Sunda Shelf Seas

et al. 2023

Radiochemical separation techniques were applied to measure 210Pb radioactivity in samples to determine spatial distribution of total 210Pb radionuclide in surface sediments and water column for the main waters on the Sunda Shelf. The average 210Pb radioactivity level recorded for the Malacca Strait (MS) is significantly higher than that of the southern South China Sea (sSCS); this is attributed to the supply of input from the Andaman Sea in its northern areas, and massive terrestrial processes from bordering land masses. The results reveal that the decreasing trend of total 210Pb in Peninsular Malaysia’s marine sediment starts with the north maritime zone of Malacca Strait (64.28 ± 5.97 Bq/kg) > south maritime zone of Malacca Strait (50.88 ± 6.15 Bq/kg) > east maritime zone of sSCS (41.01 ± 3.07 Bq/kg) > south maritime zone of sSCS (40.78 ± 3.16 Bq/kg). The Kelantan and Pahang Deltas have been identified as two of the main anthropogenic sources of input for total 210Pb in the sSCS with atmospheric transboundary mobilization affecting total 210Pb in the water column. In the Malacca Strait, however, the distribution of total 210Pb might be influenced mainly by in situ processes of the strait’s seafloor and sources origin of sediment.
