Abstract

This research purpose is to analyze the effectiveness of mangrove ecosystem management strategy in Bunaken Island of Bunaken National Park in Manado City, North Sulawesi Province. The research used the research methods of field surveys, sampling, and literature studies for several components that require periodic data. The data analysis used in this research is the Criteria Decision Making Analysis (MCDMA) with the Rapid Appraisal of Mangrove Ecosystem Sustainability (RAPMECS) tools modified from the Rapid Appraisal for Fisheries (RAPFISH). The obtained data will analyze the effectiveness of the ecological, socio-economic, and institutional dimensions that directly affect the mangrove ecosystems. It is indicated that the mangrove ecosystem management sustainability dimension in Bunaken Island is poor, and the socio-economic and institutional dimensions are not good. The main point that makes the management sustainability dimension unfavorable is the island slope and total extent of the mangrove ecosystem area. As the buffer zone, the mangrove ecosystem is low effective, this island is vulnerable to sea currents and waves. The strategies to minimize the vulnerability of this island from sea currents and waves include the increase of the mangrove ecosystem area, community awareness and participation in managing the mangrove ecosystems, and the supporting infrastructure in the mangrove ecosystem management activities.Keywords: Strategy; Management; Mangrove; BunakenABSTRAKKajian ini bertujuan untuk menganalisa efektivitas strategi pengelolaan ekosistem mangrove Pulau Bunken, yang masuk dalam kawasan Taman Nasioanl Bunaken di Kota Manado Provinsi Sulawesi Utara. Kajian ini menggunakan metode penelitian antara lain  survei lapangan, sampling, dan studi literatur pada beberapa kompenen yang membutuhkan data berkala. Analisis data bersifat Multy Criteria Decision Making Analysis (MCDMA) dengan tools Rapid Apraisal of mangrove ecosystem sustainability (RAPMECS) yang dimodifikasi dari the Rapid Appraisal for Fisheries (RAPFISH). Data yang didapatkan untuk menganalisa efektivitas dimensi ekologi, sosial-ekonomi, dan kelembagaan yang mempengaruhi ekosistem mangrove. Pada dimensi ekologi terindikasi keberlanjutan pengelolaan ekosistem mangrove di Pulau Bunaken kurang baik, sedangkan pada dimensi sosial ekonomi dan kelembagaan kurang baik. Hal utama yang membuat keberlanjutan pengelolaan pada dimensi ekologi kurang baik adalah kemiringan lereng pulau dan luasan dari ekosistem mangrove. Akibat dari rendahnya efektifitas mangrove sebagai buffer zone membuat pulau ini rentan terhadap aksi laut yaitu arus dan gelombang. Strategi yang dapat dilakukan meminimalkan kerentanan pulau ini antara lain adalah penambahan luasan ekosistem mangrove, peningkatan kesadaran dan partisipatif  masyarakat dalam pengelolaan ekosistem mangrove, dan peningkatan infrastruktur pendukung dalam kegiatan pengelolaan ekosistem mangrove.Kata Kunci: Strategi; Pengelolaan;  Mangrove; Bunakensupporting infrastructure in the mangrove ecosystem management activities.

Abstract

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
