N2  - Gastropods and bivalves are the most common types of molluscs found living in
mangrove ecosystems. Molluscs are one of the organisms that have an important role
in ecological fungi in mangrove ecosystems. The study aimed to analyze the structure

of gastropod and bivalve communities, analyzed water and sediment quality, and ana-
lyzed habitat characteristics and relationships between observation parameters at each

research station. The research was located at the mangrove forest area of Labuhan
Maringgai District. The structure of gastropod and bivalve communities was analyzed
using the Shannon-Wienner index method which included data on abundance index,
diversity index, uniformity index, and dominance index. Analysis of the relationship

between water quality and mangrove vegetation and biota using the principal com-
penent analysis (PCA) method. The location of Margasari and Sriminosari villages is

dominated by Avicennia marina mangrove species. There were 13 species from 6
families of gastropod class and 2 species from 2 families of bivalve class are found.
The quality of the waters obtained had quite good results for the life of gastropods
and bivalves. Each research station had its own habitat characteristics. The abundance
of gastropods and bivalves had a positive relationship with several parameters such as
dissolved oxygen (DO), mangrove density, and salinity. The abundance of gastropods
and bivalves had a negative relationship with pH and temperature.

Keywords: Mangrove, community structure, gastropods, bivalves.
Gastropoda dan bivalvia merupakan jenis moluska yang paling banyak ditemukan

hidup pada ekosistem mangrove. Moluska adalah salah satu organisme yang mempu-
nyai peran penting dalam fungi ekologis pada ekosistem mangrove. Penelitian ber-
tujuan untuk menganalisis struktur komunitas gastropoda dan bivalvia, menganalisis

kualitas perairan dan sedimen, serta menganalisis karakteristik habitat dan hubungan

antar parameter pengamatan pada setiap stasiun penelitian. Penelitian berlokasi di ka-
wasan hutan mangrove Kecamatan Labuhan Maringgai. Struktur komunitas gastro-
poda dan bivalvia dianalisis menggunakan metode indeks Shannon-Wienner yang

meliputi data indeks kelimpahan, indeks keanekaragaman, indeks keseragaman, dan

indeks dominansi. Analisis hubungan antara kualitas perairan dengan vegetasi man-
grove dan biota dengan menggunakan metode principal compenent analysis (PCA).

Lokasi Desa Margasari dan Sriminosari didominasi oleh jenis mangrove Avicennia
marina. Terdapat 13 spesies dari 6 famili kelas gastropoda dan ditemukan 2 spesies
dari 2 famili dari kelas bivalvia. Kualitas perairan yang diperoleh memiliki hasil yang

cukup baik untuk kehidupan gastropoda dan bivalvia. Setiap stasiun penelitian me-
miliki karakteristik habitatnya masing-masing. Kelimpahan gastropoda dan bivalvia

memiliki hubungan positif dengan beberapa parameter seperti oksigen terlarut (DO),
kerapatan mangrove, dan salinitas, sedangkan kelimpahan gastropoda dan bivalvia
memiliki hubungan negatif dengan pH dan suhu.
