Abstract

This study was conducted at Sako Beach, Bungus Teluk Kabung District, Padang City, West Sumatra, to analyze the physical parameters of the water and examine changes in the shoreline occurring in the area. Data collection was conducted in November 2024 at five observation stations located using GPS. The measured parameters included water temperature, salinity, current velocity, and beach slope. The results showed that water temperatures ranged from 34 to 35°C, which is relatively high for tropical coastal waters. Salinity values ranged from 15 to 22 ppt, indicating brackish water characteristics and the influence of freshwater runoff from the land. Current velocity ranged from 0.1 to 0.25 m/s, falling into the category of weak to moderate currents, while the beach slope ranged from 0.744° to 2.919°, indicating a gently sloping beach. These physical conditions are interrelated and play a role in coastal dynamics, particularly in sediment distribution. Analysis of shoreline changes indicates that Sako Beach is undergoing accretion, or land gain, driven by sedimentation. The gentle slope influences this process, as does relatively low wave energy and the potential contribution of terrestrial runoff. The results of this study show that the dynamics of physical water parameters play a significant role in shaping changes in coastal morphology; therefore, periodic monitoring is necessary to support sustainable coastal zone management

Abstract

An application is a subclass of computer software that utilizes the computer’s capabilities directly to perform a task desired by the user. The purpose of this study was to investigate bathymetric mapping techniques using Planet Scope satellite imagery and methods for processing data collected in the field. The research was conducted from January to February 2019 at the Remote Sensing Laboratory of the Oceanography Research Center, Indonesian Institute of Sciences (P2O-LIPI), East Ancol, North Jakarta. The methods used during this internship included active participation and literature review. To this context, the author processed satellite image data and analyzed the data using a laptop equipped with ArcGIS 10.5, Microsoft Excel, and ENVI 5.3. The results from data processed manually to determine absolute depth exhibited a higher level of accuracy ompared to data processed automatically
