The research purpose aims at analyzing the structure of the existing mangrove communities along the coastal area of Morowali District, Central Sulawesi Province. The sampling was taken from three villages, i.e. Maratape Village, Lafeu Village, and Labota Village. This research used the quadrant line transect method. The analysis and description were made after the method had been conducted. The composition of mangrove species found in this research was 3 (three) types, i.e. Rhizophora apiculata, Sonneratia alba, and Rhizophora stylosa. Of the three species the research finds, the dominant ones are Rhizophora apiculata and Sonneartia alba. The highest species density values were found at Station 1 (M01), i.e. R. apiculata. The frequency value had the highest value found at Station 2 (M02), i.e. R. apiculata type, and the highest relative frequency was R. apiculata. The highest closing value, i.e. S. albater type could be found at Station 2 (M02). The importance value index of Rhizophora apiculata type at the Station 1 (M01) had the highest value and followed in Station 3 (M03), i.e. Sonneratiaalba type, the lowest INP analysis in all stations was Rhizophora type stylosa. The dominant mangrove in 3 (three) Morowali District Stations were Rhizophora apiculata and Silneratia alba types. Based on the research results conducted on the structure of mangrove ecosystem communities in Morowali District, Central Sulawesi Province (Maratape Village Menui Kepulauan Sub-District (station 1), Lafeu Village Bungku Pesisir Sub-District (station 2) and Labota Village Bungku Tengah Sub-District (station 3) are definitely classified as natural and have not experienced significant degradationKeywords: Community Structure, Mangrove, Morowali, Central SulawesiAbstrakKajian ini bertujuan untuk menganalisis struktur komunitas mangrove yang ada disepanjang pesisir Kabupaten Morowali Provinsi Sulawesi Tengah. Sampling dilakukan pada tiga desa yaitu Desa Maratape, Desa Lafeu, dan Desa Labota. Kajian ini menggunakan metode line transek kuadaran dilanjutkan dengan analisissnya, kemudian dideskripsikan. Komposisi jenis mangrove yang ditemukan sebanyak 3 (tiga) jenis yaitu Rhizophora apiculata, Sonneratia alba, dan Rhizophora stylosa. Dari ketiga jenis yang ditemukan yang dominan yaitu Rhizophora apiculata dan Sonneartia alba. Nilai kerapatan jenis tertinggi terdapat di Stasiun 1 (M01) yaitu R. apiculata yaitu. Nilai frekuensi memiliki nilai tertinggi terdapat di Stasiun 2 (M02) yaitu jenis R. apiculata, dan frekuensi relatif tertinggi R. apiculata. Nilai penutupan tertinggi yaitu jenis S. alba terdapat di Stasiun 2 (M02) Indeks nilai penting jenis Rhizophora apiculata di Stasiun 1 (M01) memiliki nilai tertinggi dan di ikuti Stasiun 3 (M03) jenis Sonneratia alba, analisis INP yang terendah dari semua stasiun yaitu jenis Rhizophora stylosa. Mangrove dominan di 3 (tiga) stasiun Kabupaten Morowali adalah dari jenis Rhizophora apiculata dan Sonneratia alba. Berdasarkan hasil penelitian yang telah dilakukan terhadap struktur komunitas ekosistem mangrove di Kabupaten Morowali Provinsi Sulawesi Tengah (Desa Maratape Kecamatan Menui Kepulauan (stasiun 1), Desa Lafeu Kecamatan Bungku Pesisir (stasiun 2) dan Desa Labota Kecamatan Bungku Tengah (stasiun 3) masih tergolong alami dan belum mengalami degradasi yang berarti.Kata kunci : Struktur komunitas; Mangrove; Morowali; Sulawesi Tengah
