ABSTRACT

Indonesia as an archipelagic country is very dependent on sea transportation, so it needs reliable port facilities and infrastructure. Tegal port is one of the commercial ports that has become a priority for port development in Indonesia. The study aims to be a frame of reference for the development plan for Tegal port. The research parameters are seawater quality using atomic absorption spectrophotometry, wind data based on windrose results, bathymetry base on Singlebeam Echosounder, ocean wave data using the ADCP SonTek Argonaut-XR, basic sediment sample data with Wentworth Scale classification. The results of sea water quality is TDS, pH, sulfide, Cd, Cu, Hydro Carbon, Surfactants and Zn that exceed the quality standard. Wind conditions indicate the dominant wind direction from the south (43.7%). The second dominant direction from the Southwest is 19.8 % with a dominant speed of 2 - 4 knots (63.7%). The average speed of the dominant direction is 4 knots. Overall water conditions are very gentle. Depth to - 5.0 m is found at a distance of 300-400 m from the coastline. The water area is affected by east wind and west wind which can cause high waves up to 1.0-1.5 meters. The tidal difference is estimated to be around 1.5-2.0 m, including the moderate tidal category, the water depth ranges from -2.00 to 2.50 mL MLWS. The type of tidal type is a predominantly semidiurnal mixture with a tidal mount value of 1,276 meters. Sedimentation of ± 2.00 meters has occurred. Biological parameters show damage to coral reef ecosystems. The index of plankton diversity > 2 is the good category. The research is expected to be used a reference framework for the development plan of Tegal ports.
