Abstract

The researches on wave attenuation in the past has been carried out on several types of mangroves. The researches were either conducted in the laboratory or done using mathematical models. Therefore, this research with the object Avicenia marina mangrove was conducted in the field. The aim of this research was to determine how much mangrove Avicenia marina dampens wave energy. The Research was done at a location within the Indah Kapuk Coastal Area of Jakarta, Indonesia by dividing it into based on the width of the mangrove groves i.e., 5, 10, 15, 20 and 30 m. Wave measurement was carried out using the SBE26 type wave gauge. Gauges were mounted in front of the mangrove groves and behind the mangrove groves. The raw data obtained from observations were processed using FFT, MATLAB program and statistics. Attenuation by mangroves with 5 m width was 22.268 (m sec-1)2/c 2 min "), 15 m thickness 8.698 (m sec-1)2/c 2 min ") and 30 m thick 5.878 (m sec-1)2/c 2 min "), The wave attenuation formula obtained as the relationship between the thickness of the mangrove and energy was Y (Energy) = 0.003x3+0.208x2-4.620x+40.29. The conclusion was that the thicker the mangrove groves, the greater the energy muted.
