Abstract

The Kampar River Estuary is the main river in Riau province, which empties into the Malacca Strait and has a unique potential for research. The characteristics of the Kampar River Estuary are concurrent and have high tidal elevations, resulting in the occurrence of a Tidal Bore, which is referred to as Bono. The impact of sedimentation is generally quite detrimental, namely the siltation in several places, such as the waters of the Kampar River Estuary, which are dense areas of human activity. This study aimed to determine the relationship between hydrodynamic patterns, suspended solids' distribution pattern, and the concentration value of suspended solids distribution in the Kampar River estuary. This research method is surveyed and discussed descriptively. Current patterns affect the distribution of sediments in the Kampar River estuary. The TSS distribution pattern tends to follow the same direction as the movement of tidal currents where, during high tide, it tends to lead to the southwest of the Kampar River estuary, while during low tide tends to lead to the northeast and northwest, it this is because, in the Kampar River estuary, there is an island that makes the mouth of the Kampar River estuary V-shaped. Between hydrodynamic patterns and TSS distribution patterns, there is a moderate negative relationship (r = 0.50), which means that there is a significant influence between hydro patterns and TSS distribution patterns in the waters of the Kampar River estuary, between hydrodynamic patterns and TSS distribution patterns in the waters of the Kampar River estuary. The lowest value of TSS concentration in the waters of the Kampar River Estuary at high tide to low tide is Station 7, with a range of 102 mg/L, and the highest value at Stations 3, 4, and 9. At station 3, there are values ranging from 1756 mg/L; at Station 4, there are values ranging from 2823 mg/L; and at Station 9, there are values ranging from 1269 mg/L; the high concentration of TSS results in low brightness in the study area

Abstract

The Indian Ocean Dipole (IOD) phenomenon is a phenomenon that occurs in the Indian Ocean due to differences in sea surface temperature anomalies between the Western Indian Ocean and Eastern Indian Ocean regions. This interaction produces high pressure in the Eastern Indian Ocean (South of Java and West of Sumatra) which causes the flow of air masses to blow westward. The IOD phenomenon affects oceanographic parameters such as sea surface temperature, salinity, currents, and sea level rise in Indonesian waters. The Malacca Strait is a very important waterway because it connects the Indian Ocean and the South China Sea (Pacific Ocean) so it is strongly influenced by the IOD phenomenon. This research was conducted from November 2022 - February 2023. Global data collection in this study was located in the waters of the Strait of Melaka and data collection for validation was carried out in the waters of North Rupat. This study uses data analysis using secondary data and primary data to validate the secondary data used so that it can prove that the global data in this study are accurate. The results of this study found that in the period 2013 - 2022, the range of sea surface temperature of the Malacca Strait is 27 - 32°C. The salinity of the Malacca Strait waters ranges from 32.54 - 33.49 ppt. The current speed in the Malacca Strait is classified as weak to strong with the direction of movement of the Malacca Strait ocean currents back and forth. The Malacca Strait waters have a mixed tidal type of double daily inclination with an F value of 0.6 cm. The sea level rise in the Malacca Strait ranges from 0.50 - 0.76 cm. The IOD phenomenon affects sea surface temperature, salinity, sea level rise, and current velocity depending on the IOD phase.

Abstract

This research examines the influence of the Indian Ocean Dipole (IOD) and El Niño–Southern Oscillation (ENSO) on sea surface temperature (SST) and rainfall variability in the coastal waters of West Sumatra over the period 2014–2024. The analysis draws on the Dipole Mode Index (DMI), Niño 3.4 index, SST, and rainfall data, processed using MathWorks and Excel. Regression analysis between field and satellite-derived SST data showed a strong correlation (R² = 0.936), confirming the reliability of satellite data for this study. Findings reveal that positive IOD and El Niño events are generally associated with cooler SSTs and reduced rainfall. In contrast, negative IOD and La Niña phases correspond to warmer SSTs and increased rainfall. The IOD appears to exert a more pronounced influence on SST variability than ENSO. Notably, the combined occurrence of a positive IOD and El Niño amplifies the decline in SST and rainfall. At the same time, the combination of a negative IOD and La Niña enhances increases in these variables. These results highlight the significant role of large-scale climate mode in shaping regional oceanographic and atmospheric conditions in the West Sumatra region.
