| Summary: | Information about sea tides is very important information in various marine needs
such as maritime affairs, sea transportation, natural resources, development in the
Coastal area, marine engineering planning, and other activities. Information that can
be obtained through station observation uses tide palm, but the results of this
observation only apply to the surrounding area associated with the port, while the
tidal characteristics in the Coastal area are different from the tidal characteristics of
the high seas. An alternative method that can be done for measuring tides on the high
seas is using Altimetry satellites. In this study a map of Indonesian tidal information
was made consisting of co-tidal maps (amplitude and phase), tide and tide based on
Altimetry satellite data, namely Topex, Jason-1, Jason-2, and Jason-3 from 1992 up
to 2019. With the Altimetry satellite data obtained the Sea Surface Height (SSH)
value so that with this data tidal component values can be obtained using the
response method. With the value of the tidal component, it can be seen the tidal
characteristics in the Indonesian region produced by the Indonesian tidal map that
can be used as consideration in making decisions on marine activities. Based on the
results of research conducted, the amplitude values in Indonesian ships vary greatly
for each component of the tide. The highest amplitude value of the passive
component (M2, S2, K1, O1) is M2 with an average of 28.94 cm. This amplitude
value can represent the characteristics and type of tide, where there are four types of
tides in Indonesia, namely semi diurnal around the Malacca Strait to the Andaman
Sea, semi-diurnal dominant mixed tidal types available in most of southeastern
Indonesia, diurnal dominant mixed tidal in the southern part of Java Island, and
diurnal tide types are in the Karimata Strait which is between the islands of Borneo
and Sumatra. While the highest tidal mounts in the Arafura Sea are 3-4 meters.
