Abstract

This study aims to report the diversity of the Halimeda genus on the West Aceh coast. Data was collected in the Lhok Bubon Coastal intertidal area, Samatiga, West Aceh Aceh Province. Macroalgae samples were collected using the cruising method along the beach with a depth of 1-2 m at low tide. The Halimeda genus found four species, namely Halimeda macroloba, Halimeda macrophysa, Halimeda incrassata, and Halimeda simulans. Halimeda macroloba was found to have a whitish-green talus. Halimeda macrophysa samples have irregular talus branches. Description Halimeda incrassata at the study site is light green, and the holdfast is attached to the sandy substrate to form large sediment clumps. Halimeda simulans were found to be linked to sand, which tends to have a finer texture. The results of this report provide information that Lhok Bubon Beach, West Aceh, has macroalgae potential that needs further study.

Biodiversitas 18: 1438-1444.. Darmarini AS, Wardiatno Y, Prartono T, Soewardi K. 2017. Short Communication: New record of primitive brachiopod, Lingula sp. in mangrove ecosystem of Lubuk Damar, Aceh Tamiang, Indonesia. Biodiversitas 18: 1438-1444.. This study reports the occurrence of the primitive brachiopod, Lingula in mangrove ecosystem as a new record in Indonesia. Specimens were collected from the mangrove sediment at a depth of between the sediment surface and 20 cm beneath. . Lingula has a glossy shell and oval-ovate shell shape. The color of shell is brownish or greenish. In posterior a point where pedicle occurs is found. The pedicle is a prolongation of the body like an anchor, with varying length, rough, hard and striped texture. Pedicle has soft transparent layer and the edges are covered by the substrate. The inside body of Lingula, there is a lophophore, which is the characteristic of this species The total length of the brachiopod ranges from 3-122 mm. The texture of habitat consists of 39.67% sand, 50.95% silt, and 11.45% clay.
