“…The high Chl-a concentration is found near the mainland where there are many estuaries in the surrounding, so that the intake of nutrients from land and the river has become a major factor influencing this condition. A nutrient is the basic element in the process of photosynthesis, the higher presence of nutrient, the higher productivity of autotroph biota population (Wisha & Maslukah, 2017).…”

<p>Belitung Island has a strategic geographical location, which is directly bordered with Sumatera and Kalimantan also Karimata and Malacca Straits. Those conditions make the waters productivity being high due to the support from the biogeochemical cycle, nutrient runoff, and upwelling. This study aims to determine the seasonal variability of chlorophyll-a (Chl-a) around Belitung waters. The method used in this study was spatial analysis with IDW (inverse distance weighted) to interpolate the Chl-a surface distribution. Sea Surface Temperature (SST) acquired from Aqua-MODIS were retrieved from NASA (National Aeronautics and Space Administration) and wind data were obtained from ECMWF (European Centre for Medium-Range Weather Forecasts), data were analyzed statistically and spatially. The Chl-a concentration in the northeast monsoon ranged 0.38-3.5 mg.m-3, in the southwest monsoon ranged 0.15-18.7 mg.m-3, and in the transitional season ranged 0.29-9.04 mg.m-3. The Chl-a concentration during southwest and 1st transitional monsoons were higher due to the maximum sunlight intensity stimulating photosynthesis of autotroph biota. The condition of SST is indicating the upwelling event that involves wind-driven motion of dense, cooler, and usually nutrient-rich water towards the ocean surface. Seasonal SST variability ranged 22.6-28.3oC, 27.3-32.1oC, 30.7-32.3oC, and 29.1-32.8oC during northeast, 1st transitional, southwest, and 2nd transitional monsoons respectively. The existence of ENSO (El-Nino Southern Oscillation) contributes to enhance the Chl-a concentration. During ENSO years, the Chl-a concentration was higher than non-ENSO years due to the great impact of ENSO inducing upwelling and higher nutrient availability. Chl-a and SST conditions can be used to predict fishing ground and upwelling area. </p>

“…This disrupts the propagation of Bono waves (Chanson, 2001). According to Wisha and Maslukah (2017), the elevation changes drastically during the propagation Bono waves, which triggers the mass transport of water that enters the river rapidly with the speed reaching 0.85 m/s. It is the one factor triggering the sedimentation and erosion events along the Kampar River.…”

Abstract. The Kampar River estuary is well known for a tidal-bore phenomenon called system of Kampar River. Scoured materials, resulting from the hydraulic jump of the tidal bore, are carried into the middle of the river. These materials are then deposited when the velocity of the river decreases as a result of the collision of the tidal current sedimentation with respect to the river line and perform land-cover change analysis for the area around the Kampar River estuary for the years of 1990, 2007, 2010 and 2016. which uses an overlay technique to yield alternate information on the river line and land-cover changes in the form of time-series data. The largest erosion occurred during plantations (11.57 ha/year), building/settlement (48.11 ha/year) and scrubland (30.88 ha/year). The other types of land cover, such as bare land and sediment deposition, varied every single year. The changes to the river line are caused by land-cover changes, and the Bono waves that lead to erosion and sedimentation that is not stable in the middle of the river and downstream.Keywords: spatial analysis, land cover, Bono, Landsat imagery, Kampar River estuary.

Muara sungai Kampar terkenal dengan fenomena Tidal Bore yang disebut terhadap dinamika sistem muara di sungai Kampar. Material sedimen yang teraduk karena lompatan hidrolik dari tidal bore terbawa hingga ke bagian tengah sungai. Material tersebut terendapkan ketika kecepatan arus menurun sebagai akibat dari pertemuan dua arus yaitu arus dari laut dan aliran sungai. Tujuan dari penelitian ini adalah untuk mengetahui wilayah erosi dan sedimentasi dengan menggunakan pendekatan analisis perubahan garis sungai dan tutupan lahan disekitar muara sungai

“…Because of this, the concentration of Chl-a has been used as a proxy for eutrophication and trophic status [ 22 , 23 ]. Several studies have also examined the relationship between climate and the phenological cycle variations of phytoplankton [ 16 , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] ].…”
