“…Mangrove is plant communities that grow in coastal saline or brackish water and functioned as protectors of the coastal area from erosion, storm sturge and tsunami. Langsa is a city in Aceh province with 262.41 km 2 of area. The mangroves in-and-around the langsa city have decreased in the area from 9550 ha in 2013 to 7837 ha as of 2015, during this time commercial shrimp aquaculture has become the dominant land-cover within this estuary environment.…”

“…waterlogging, unstable and oxygen-deficient soils, and high salinity. 2 Any kind of plant that able to cope with this condition, usually will be able to have a new metabolic pathway and produce a specific metabolite that can be utilized to support its life. 3 From the previous study, mangrove plants consisted of several secondary metabolites, such as alkaloid, saponin, tannin, and flavonoid.…”

Mangrove has special properties, i.e. able to adapt to the extreme environment. Any kind of plant that able to adapt in such a condition usually can have a different metabolic pathway and as the impact, this plant can produce a different metabolite which can act as an antibiotic. The aim of this study was to evaluate the phytochemical content and toxicity properties of Rhizophora mucronata. The functional group that presence in the extract was determined using UV-Vis and FT-IR. The phytochemical screening showed the presence of alkaloid, flavonoid, quinone, tannin and phenolic. The UV-Vis spectrum also proved the presence of phenolic (tannin) and flavonoid in the Rhizophora mucronata extract (280-390 nm). The presence of hydroxyl, carboxylic acid, aromatic C=C group was confirmed from the FTIR spectrum. The toxicity property of ethanolic extract of Rhizophora mucronata showed LC 50 of 636.73 ppm ≤ 1000 mg/L.

Padang City is located on the West coast of Sumatra Island that borders directly with the Indian Ocean. The coastal region of the city stretches from Pasia Jambak beach, Muara Anai in the Northto Sungai Pisang in the South. The coast of South section is different from the coast of Northsection, because the Southern coastline is heterogeneous because there are many small bay, small islands and narrow beaches directly adjacent to the volcanic hills. This research aims to determine the dynamics condition of a coastal environment based on the characteristic (length, velocity, energy, and height), sediment transport value, accretion/abrasion factor value, and coastal equilibrium in Padang City.The method used in this study is the calculation of wavelength (L0 ), wave velocity (C), wave energy (E), run-up height (Hb ), and sediment transport (Q) to determine accretion/abrasion factor and equilibrium (G0 ). Furthermore, it is done by Geographic Information System (GIS) approach to spatial information of research location. Research result shows that coastal region(beach)in Padang City tends to experience accretion along the beach of Pasia Sabalah, Panjalinan North, Panjalinan South, Parkit, Purus South, Purus North, Muaro Padang, Air Manis North and Pasia Putih. While the abrasion conditions occur inPasia Jambak, Parupuk Tabing, Bung Hatta University beach, Air Manis South and Sungai Beremas.

The research about the identification of mangrove physical condition and the change of mangrove area has aims are knowing of mangrove physical condition and the change of mangrove area in the coastal region southern part of Padang city. The method used in this research is the field survey and multi-temporal satellite imagery analysis in 2001 and 2018 year. Based on the field survey at the date of August 18, 2017 generally the mangrove that found in research location i.e Rhizophora Apiculata, Rhizophora mucronata, Sonneratia alba, and Nypa. The spatial distribution of the mangrove ecosystem is dependent on the ecological conditions of the area as reflected by the types of mangrove vegetation that grows and develops in the research location. A decrease in mangrove area that occurred between of 2001 to the 2017 years i.e in the coastal region of Bungus bay i.e 5.54 ha, where the decrease in mangrove area occurred because some mangrove plants were cut down and made the settlement land, while in the region of Sungai Pisang bay happen to increase in mangrove area i.e 36.12 ha, where the increase in mangrove area occurred because of the region obstructed by big waves of the sea (protected small the islands).
