Abstract

The mangrove ecosystem is an ecosystem that grows above the brackish marshes that are located on coastlines and influenced by the tides of the sea water. The conditions of the mangrove ecosystem continue to experience widespread decline and change in density especially on the coastal area of Bungus Teluk Kabung. The study was conducted in June – August 2019. The purpose of this research is the major analysis of the rate of change of mangrove land cover, analysis of perception/community opinion about the conditions and efforts made by the Government of the mangrove and analysis of the condition of the mangrove ecosystem. The method used is a quantitative approach to descriptive. The result is a mangrove land cover of 2009 covering an area of 80.71 ha while the year 2019 is 60.35 ha, the rate of change (-25,23%/10 year), the change in mangrove area with a change rate of-100% found in the location of Teluk Sirih where the year 2009 (8, 82ha), and the year 2019 (0 ha). The change occurred due to the construction of the PLTU of Teluk Sirih. With the increase of mangrove ecosystem in the area of Pertamina Jetty because of the rehabilitation of local government. Its expansion in the year 2009 (3.06 ha) became the year 2019 (3.96 ha) with the addition of 0.90 ha and the rate of change of 29.41%. NDVI values of 2009 in 0.60 with normal vegetation density conditions and the year 2019 NDVI values in 0.42 with good vegetation density conditions.

Abstract

Mangrove is a plant that can live in tidal areas and form a community of independent vegetation, ranges to various disorders, especially marine resource management that is not environmentally friendly causing damage to the Mangrove forest. Thus researched to know the condition, the rate of change in land area and public response to the mangrove ecosystem implemented in August 2019 using Phantom 4 Drone data and a descriptive method Quantitative. The results were adopted, namely, the condition of the mangrove ecosystem was declared normal (0.22) in the year 2009 using NDVI value classification, as well as the year 2019 NDVI value of 1 in the condition is very good. The area on land cover amounted to 406.61 ha in 2019, while the year 2009 amounted to 406.69 ha with a change of-0.08 ha. Mangrove conditions with an area of 79.13 ha in 2009, a decline in 2019 of 60.01 ha, a change of-19.12 ha (-24.16%). The mangrove ecosystem is getting worse because of the road construction that causes some material to fall into the mangrove area that makes the sedimentation wider, as occurs in the segment 3 The change of mangrove overflow from the year 2009 (21.60 ha) 19.83 ha in the year 2019. People are still promoting the economy compared to the survival of mangroves because the existence of mangroves is considered economically beneficial for them.
