Abstract

Mangrove is important life support ecosystems in coastal and marine areas that have bio-ecological and socio-economic functions. Mangroves are found in tidal areas that have the ability to grow in salty waters and have a role as a barrier to abrasion. Mangrove plants have special adaptability to the environment such as adaptation to low oxygen levels, high salinity and less stable soils. Indonesia has the largest mangrove ecosystem and the highest biodiversity in the world. This study aims to determine the index of diversity and structure of mangrove communities in Hutan Lindung Angke-Kapuk (HLAK) and Taman Wisata Angke (TWA) Angke-Kapuk which is divided into 11 points. The research was carried out on November 15 to 30, 2021 using purposive sampling techniques based on the representation element, which took 5% of the total area and the shape of a square plot with a size of 50x50 meters. The results showed that 11 family, 12 genus and 15 species of mangroves were found, the type was divided into 8 species of true mangroves and 7 species of mangroves followed. The extinction rate of mangrove species in HLAK and TWA Angke-Kapuk amounted to 1.25. The level of type similarity between research points in the HL Angke-Kapuk and TWA Angke Kapuk areas in 2020 and 2021, showed a slight change in the level of type similarity at each point. The dominant type of seedling and sapling tree level is the Avicennia marina type. Mangrove diversity index (H’) in the area of HLAK and TWA Angke Kapuk is 1.6.

Abstract

Birds are a good indicator for identifying areas rich in biodiversity, including environmental changes and problems. The reduced number of birds also indicates environmental degradation. Birds play an important role in an ecosystem in maintaining biological balance. These roles include pollinating plants, controlling insect populations and playing a role in the dispersal of plant seeds. In fact, several species of birds are considered key species where their presence in an ecosystem can indirectly influence the existence of other species. Birds need a habitat that acts as a source of food, a place to socialize, reproduce, take shelter, rest and nest. The mangrove area in the Angke-Kapuk Muara Angke Protected Forest is an important bird area or Import Bird Area. The method used is the Visual Encounter Survey (VES). Each species of avifauna found at the observation location was recorded and counted. Bird watching is carried out in the morning at 06.30 – 09.30 WIB. Observations are carried out using a transect route, that is, the observer will walk along the existing observation route. This research will be carried out in the Pantai Indah Kapuk area, namely in the Angke-Kapuk Muara Angke Protected Forest, North Jakarta. This research was conducted in November 2023. This research aims to determine the species composition and diversity of avifauna species at Pantai Indah Kapuk, North Jakarta. Based on the results of research conducted at 11 locations in the Pantai Indah Kapuk area, it was found that there were 62 species of birds from 31 families. The highest number of bird species was found in plot 1, namely 44 species belonging to 24 families and plot 9, namely 36 species belonging to 23 families.
