ABSTRAK: Ekosistem mangrove adalah komunitas tumbuhan tropis yang berada di daerah tepi pantai yang memiliki kemampuan adaptasi pada perairan asin di wilayah intertidal yang dipengaruhi oleh pasang surut air laut. Struktur komunitas mangrove merupakan salah satu parameter dalam menentukan kondisi mangrove. Kawasan ekosistem mangrove yang memiliki karakteristik dinamis komposisi jenis mangrove terdapat di Segara Anakan. Akan tetapi memiliki penurunan luasan hutan mangrove. Hal ini adanya beragam faktor kondisi lingkungan di Segara Anakan, sehingga menyebabkan variabilitas mangrove wilayah Segara Anakan berbeda. Namun kondisi terkini belum banyak dilakukan dalam suatu penelitian sehingga dibutuhkan informasi ilmiah terkini untuk mengetahui komposisi jenis mangrove. Untuk mengatasi hal tersebut maka dilakukan penelitian struktur komunitas untuk mengetahui kondisi ekologi mangrove di Segara Anakan. Tujuan penelitian ini adalah menggambarkan kondisi struktur komunitas mangrove di muara timur Segara Anakan. Lokasi penelitian berada di muara sungai bagian Timur (Sungai Donan). Metode yang digunakan dalam penelitian ini adalah metode deskriptif. Penentuan titik pengambilan data atau sampel di setiap lokasi dilakukan dengan teknik purposive sampling. Selain itu, digunakan teknik transek kuadrat 10x10 m dan Hemispherical Photography. Hasil penelitian menunjukkan kerapatan pohon sebesar 90,6 /ha. Kerapatan sapling rata-rata bernilai 1023 /ha. Kerapatan seedling bernilai 1746 /ha di Muara Timur. Tutupan kanopi komunitas mangrove memiliki persentase kurang dari 75%. Tinggi dan diameter pohon didapatkan sebesar 5,97 m dan 3,1 cm. Spesies mangrove yang ditemukan di dalam plot berjumlah 10 spesies mangrove yaitu Rhizophora apiculata, Bruguiera gymnorrhiza, Aegiceras corniculatum, Avicennia marina, Avicennia alba, Ceriops tagal, Ceriops decandra, Sonneratia caseolaris, Sonneratia alba, Scyphiphora hydrophyllacea, Xylocarpus moluccensis, Xylocarpus granatum, Talipariti tiliaceum, dan Nypa fruticans. ABSTRACT: Mangrove ecosystems are communities of tropical plants located on the coast that have the ability to adapt to salty waters in intertidal areas which are affected by tides. Mangrove community structure is one of the parameters in determining mangrove condition. Mangrove ecosystem areas that have dynamic characteristics of mangrove species composition are found in Segara Anakan. However, it has decreased the area of mangrove forests. This is because of various environmental conditions in Segara Anakan, causing variability of mangroves in the Segara Anakan area to be different. However, recent conditions have not been carried out in many studies, so the latest scientific information is needed to determine the species composition of mangroves. To overcome this, a community structure research was conducted to determine the ecological conditions of mangroves in Segara Anakan. The purpose of this study was to describe the condition of the mangrove community structure in the eastern estuary of Segara Anakan. The research location is in the mouth of the eastern river (Donan River). The method used in this research is descriptive method. Determination of data collection points or samples at each location was done by using purposive sampling technique. In addition, the 10x10 m quadratic transect technique and Hemispherical Photography were used. The results showed the tree density was 90.6 ind/ha. Saplingaveraged 1023 ind/ha. The density seedling is 1746 ind/ha in Muara Timur. The canopy cover of the mangrove community has a percentage of less than 75%. The tree height and diameter were 5.97 m and 3.1 cm respectively. There are 10 mangrove species found in the plot, namely Rhizophora apiculata, Bruguiera gymnorrhiza, Aegiceras corniculatum, Avicennia marina, Avicennia alba, Ceriops tagal, Ceriops decandra, Sonneratia caseolaris, Sonneratia alba, Scyphiphora hydrophyllacea, Xylocarpus moluccensis, Xylocarpus granatum, Talipariti tiliaceum, and Nypa fruticans.

Mangrove litter production is important in the displacement of organic matter from mangrove vegetation to water such as in the coast of West Muna Regency. However, one factor influencing it is the frequency of rainfall. This research, therefore, aims to determine the influence of the frequency of rainfall in mangrove ecosystem by obtaining data through the fractional wet weight. The results showed that the biomass fraction with the largest amount were Rhizophora mucronata, Rhizophora apiculata, and Sonneratia alba with of 31.59; 31.07; and 30.96%, respectively, while the lowest was Rhizophora stylosa, Bruguiera cylindrica, and Bruguiera gymnorrhiza with of 30.07; 30.10; and 31.95%, respectively. The species with the largest leaf litter production was Bruguiera cylindrica, with of 1.72 g.m-2.day-1 which occurred in April and the lowest was Rhizophora apiculata, 0.24 g.m-2.day-1 in August. The species with the largest leaf litter production was Bruguiera cylindrica, 1.96 g.m-2.day-1 which occurred in May and the lowest was Sonneratia alba, 0.29 g.m-2.day-1 in August. In addition, the species with the largest fruit litter production was Rhizophora apiculata, 1.76 g.m-2.day-1 in April and the lowest was Sonneratia alba, 0.32 g.m-2.day-1 in September. The total litter production was 18,75 g.m-2.day-1 consisted of 6,69 g.m2.day-1 leaf litter, 6,54 g.m-2.day-1 branch litter, and 5,52 g.m-2.day-1 fruit litter. The higher the frequency of the rain, the greater the litter production.   Keywords: biomass fraction, seasonal litter production, West Muna Regency
