Comparison of Waves Reduction by Mangrove Avicennia Marina in East Lampung and Indah Kapuk Beach, Indonesia

Abstract

Abstract Mangrove Avicennia Marina has important role in wave reduction. The purpose of this research were: (1) To know wave energy ratio in Indah Kapuk Beach and East Lampung Regency, Indonesia. (2) To know the influence of Avicennia Marina mangrove’s respiratory roots on wave energy reduction. Measurement of wave in Indah Kapuk Beach used SBE26, in East Lampung used SBE26 and RBRDUO TD. Parameters were the structure of mangrove vegetation and wave energy reduction. The wave observed in Indah Kapuk Beach tends to be smaller than in East Lampung, so the influence of respiratory root in reducing wave in Indah Kapuk Beach was less visible while the influence of respiratory root in East Lampung was more clearly seen. The muffled wave in the Indah Kapuk Beach research was less visible due to the presence of inhibitors obstructing the incoming waves, while the reduced wave was more clearly measured in the study in East Lampung because without an inhibitors of wave coming.
