Abstract

Kawasan pantai Larantuka berada di pantai timur Pulau Flores dan kaki Gunungapi Ile Mandiri membentuk bentang alam pesisir bertebing curam dan landai. Kawasan pesisir dapat diklasifikasikan dalam tiga tipe pantai, yaitu tipe pantai bertebing berbatu, pantai berpasir dan pantai berbakau. Tipe pantai bertebing berbatu berada pada kaki gunungapi dibatasi oleh lava. Tipe pantai berpasir merupakan kawasan pantai dengan bentang alam landai sedangkan kawasan pantai berbakau tersebar cukup luas khususnya pada teluk dangkal. Pulau Adonara didominasi oleh produk gunungapi tua yang terdiri dari lava, breksi gungungapi dan pasir-tufa gampingan. Kawasan pantai tipe bertebing berbatu ditempati oleh batugamping terumbu serta lava. Sedangkan tipe pantai berpasir yang membentuk bentang alam landai ditempati pasir serta kerikil volkanik dengan terkadang ditemui tumbuhan bakau. Kata kunci : kawasan pesisir, bakau, bongkah, dan lava Lanrantuka area lies on the eastern coast of Flores island and in the foot of the Ile Mandiri mountain. The Larantuka area has steep and slightly slopes. Coastal morphology can be classified into three beach types, steep and stony, sandy and mangrove beaches. The steep and stony beach lie on foot of a mountain with lava boulder. The sandy beach has slightly slope coast line and mangrove beach develops widely in area specially in the shallow bay. Adonara island is dominated by old volcanic products, which are composed of lava, volcanic breccia and calcareous-sandy tuff. The coastal type with steep and stony beach is covered by coral limestone and lava. The sandy beach has slightly slope coast line covered by sand and gravel volcanics with occasionally mangrove trees. Key words : coastal, mangrove, boulder and lava.
