| Summary: | <p align="justify"> Transportation safety becomes important in a development planning in the field of transportation, especially marine transportation. The influence of natural factors one of which sea waves should be the focus to be studied in the planning of marine transportation. This research aims to determine the areas that are harmful to the operation of tugboats in Indonesian Sea based on wave heights. This research was conducted by modeling the sea wave propagation using SWAN (Simulating Wave Nearshore) so that obtained a significant wave height. The data used are bathymetry and wind data from January, 1st 2017-January, 31st 2016 and August, 1st 2017-August, 31st 2016 . In addition, to support the calculation of safe wave height for tugboats, long ship data (Lpp / LOD) from several ships from PT. Pelabuhan Indonesia as sample for each size according to gross tonnage. <br />
<br />
Based on the results obtained in this simulation, it was found that the wave variations that occur in Indonesian waters are strongly bound to the monsoon wind. The pattern of variation in the mean of significant wave height in most of Indonesia's waters peaked in the December, January and February periods (DJF) as well as the June, July and August periods (JJA). The safe wave height for tugboat operation in Indonesian waters is 1.2 meters for tugboats with a size below 200 GT and then 1.4 meters for tugboats with a size of 200 GT - 300 GT and 1.6 meters for tugboats with 300 GT size. Based on the frequency of events reviewed at several points, it was found that the waters of western Sumatra and the southern waters of Java had the highest level of vulnerability, reaching 80%. In addition, based on the safe wave height limit and maximum wave height, it is found that the dangerous area for the operation of all types of tugboats in each season is the western waters of Sumatra and the southern Sunda Strait in the ALKI I region, the waters south of Java to Bali in the ALKI II region, and the Savu Sea, waters south of NTT, Arafura Sea, waters of the Sermata Islands, waters of the Tanimbar Islands in the ALKI III region. <br />
