Mangrove leaf extracts generally contain phytochemical compounds that have the potential to be antibacterial. This study aims to determine the yield of R. apiculata leaf flour and extract, the content of phytochemical compounds of R. apiculata leaf extract, and the antibacterial activity of …
Dimsum is one of the high-protein surimi products that is prone to spoilage during storage. The shelf life of catfish-based dimsum is still very limited. This study aimed to evaluate changes in sensory, chemical, and microbiological quality and to determine the shelf life of catfish dimsum at temperatures of 5±2ºC, 0±2ºC, and -10±3ºC over 28 days. The method used in this study was experim…
The red-eyed snail (Cerithidea obtusa) is one of the gastropod species that lives in mangrove environments and has potential as an alternative source of animal protein. In addition, this animal also contains various bioactive compounds, such as alkaloids, flavonoids, and saponins, which are known to have antioxidant activity. These compounds play a crucial role in neutralising free radicals tha…
Pangasius sp. is one of the most promising freshwater fishery resources in Riau Province, with its very high production making its price highly affordable. This has prompted local communities to compete in creating value-added products such as meatballs, nuggets, floss, and other processed foods. Pangasius sp. could also be utilized as a food ingredient in the form of protein concentrate. This …

Coastal ecosystems play a crucial role in supporting biodiversity but are increasingly threatened by heavy metal pollution originating from industrial and domestic activities. The mangrove species A. alba possesses the ability to absorb heavy metals through phytoremediation processes, making it a promising bioindicator of environmental contamination. This study aimed to analyze the concentratio…
Industrial and shipping activities in West Dumai pose a risk of heavy metal contamination in coastal waters, potentially leading to bioaccumulation in organisms such as Geloina erosa and Cerithidea obtusa. This study aimed to determine the accumulation of lead (Pb), copper (Cu), and zinc (Zn) in the soft tissues of both species and to compare the concentrations between species and sampling stat…
Coastal areas have high potential for natural resources, but the intensity of their utilization often leads to physical environmental changes. One of the significant impacts is land subsidence and sea level rise, which trigger tidal flooding (known as rob floods). This study aims to determine the rate of sea level rise based on tidal data analysis from 2015 to 2024, and to predict inundation ar…
