Abstract

Alas Purwo National Park in Banyuwangi Regency possesses extensive mangrove forests, including Pangpang Bay Kucur Resort in the Jati Papak Block. This mangrove ecosystem serves as habitat for various marine organisms, including Bivalvia. This research was conducted from November to December 2024, aiming to analyze abundance, identify Bivalvia species, and assess their contribution to the local community's economy, particularly shellfish collectors. The research employed purposive sampling through transects and plotting. Sampling locations were divided into three stations: Mangrove Trail, Ngaseman, and Curah Wuluh, with each station containing four transects, and each transect having 5 plots of 2 × 2 m in size, with 5-meter distances between transects and plots. Measured abiotic parameters included temperature, salinity, and pH. The research found 11 species from 8 families, with Isognomon ephippium and Brachidontes exustus being the dominant species with very high abundance. The species diversity index was classified as low, with the highest value at station 3 (0.724) and the lowest at station 1 (0.716). Socio-economically, Bivalvia contributes as a food source and seasonal income for surrounding communities, especially during low tide. This research emphasizes the importance of sustainable management to maintain the stability of mangrove ecosystems as habitat for marine organisms, particularly Bivalvia, and to improve the welfare of local communities.

Abstract

National Park Alas purwo is one the conservation areas have a fairly extensive mangrove forest and one of them is the area Bay Pangpang Blok Jati Papak. Mangrove forest have many functions that many marine organisms that occupy the regions one of the region one of which is plankton. Plankton are organisms that are generally relatively small size and its movement depends on the direction of water flow. Plankton are organisms that are generally relatively small size and its movement depends on the direction of water flow. This study aims to determine the abundance and dynamics of plankton daily in at Bay Pangpang Block Jati Papak Nasional Park Alas Purwo. This study was conducted in May-June, 2016. The method used in this research is purposive sampling to determine the point where the (station), and sampling performed every 2 hours over a period of 24 hours. Abiotic parameters include measurements temperature, pH and light penetration. The research found that 13 spec Nitzchia sp, Oedogonium sp, Vaucheria sp, Eretmocaris, Dracia moluska, Amfipod, Micracia, Glaucothoe peroni, Candacia truncata, Candacia curta, Subbeucalamus crassus, Candacia bradi dan Undinula vulgaris. The highest abundanc species of phytoplankton that Nitzchia sp, while the highest abundance of zooplankton that is Candacia truncata species. The highest dynamics of plankton occurs at the time of sampling 07.00 dean in the number of species found are 7 to fotoplankton species and 16 species of zooplankton.
