【 摘 要 】

Currently oceanographic data can be obtained through overseas websites that provide online and costless, but these online data generally have rough resolution with global or regional space coverage. The purpose of this study is to apply tidal measurements in three different waters (Surabaya, Gresik and Lamongan, East Java-Indonesia) that can transmit data via SMS gateway and store data on the web server to be accessible by people. The first step is to combine the electronic and mechanical circuits and then it was followed by experimental tools and data retrieval conducted in the laboratory. After the trial is successful, it was followed by the actual data retrieval that it tested the transmission of data from the observer station to the data center via modem that uses AT Command, a computer language program. Data will be received and stored in a web server, and then the data can be accessed via internet. The results showed that tidal instrument can work well and gave an estimated error of 3-4%. The choice of location of instrument placement was very important. The most important in this research was to avoid the crowded boat traffic and under the bridge.
