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.

Coastal ecosystems on small islands have a large enough pressure to be inversely proportional to a large island due to various resource capabilities and limited supporting factors. Mangrove is one of the ecosystems on the coast of a small island that is susceptible to disturbance because it is close to human activities. This study aimed to determine the mangrove ecosystem management strategy on the coast of the Siak Regency. The research was conducted from July to August 2020 using survey and interview methods. Data analysis used the Analytical Hierarchy Process to determine the mangrove management strategy. The results showed that community involvement is a priority for managing sustainable mangrove ecosystems with the assistance of the Government and NGOs. Management priority factors, namely ecology, while still paying attention to economic, social, institutional, and technological concerns.

North Sulawesi is one of the provinces that implements national / regional action plan (RAN / RAD) policies as part of a national effort to climate change mitigation. One of the land-based mitigation activities in North Sulawesi is to measure and monitore  biomass and carbon stocks in forests including coastal forests where the measurement area is still limited. In 2013-2015, Blue Carbon Research Group  conducted research in four locations in North Sulawesi, which aims to analyze the ecological conditions and the ability of coastal ecosystems, especially mangrove in sequestering carbon. Study sites situated in Ratatotok - Southeast Minahasa Regency, Kema - North Minahasa Regency, Lembeh Island – Bitung City and Sangihe Island – Sangihe Regency. A total of 17 species identified where B. gymnorrhiza, R. mucronata and S. alba found in all locations. Species diversity ranges from low to moderate, where species distribution is uneven. Carbon storage capacity is equal to 343.85 Mg C ha-1 in Ratatotok, 254,35 Mg C ha-1 in Lembeh, 387,95 Mg C ha-1 in Kema and 594,83 Mg C ha-1 in Sangihe. More than 59% of carbon storage are in the sediment. The average value of carbon storage in the four research sites is 456,86 Mg C ha-1 or 5,70 Tg C after converted to a total area of mangrove ecosystems in North Sulawesi. The value is equal to absorption of atmospheric CO2 by 20.70 Tg CO2e. Potential emission due to changes in mangrove conversion reach 0.42 Tg CO2e. Efforts to increase the contribution of reducing North Sulawesi emissions can be achieved by implementing emission reduction interventions through the rehabilitation and conservation of mangrove ecosystems.

ABSTRAKKajian ini bertujuan untuk menganalisa struktur komunitas dan keberlanjutan pengelolaan ekosistem mangrove di Pulau Nain Kecamatan Wori, Kabupaten Minahasa Utara, Provinsi Sulawesi Utara. Pulau Nain adalah salah satu pulau yang masuk dalam kawasan konservasi Taman Nasional Bunaken dan memiliki kawasan budidaya rumput laut yang masih produktif. Penelitian ini menggunakan data sekunder dan primer. Data yang dibutuhkan dalam kajian ini meliputi data dimensi ekologi, sosial ekonomi, dan kelembagaan. Analisis yang digunakan dalam kajian ini adalah RAPMECS (Rapid Appraisal for Mangroves Ecosystem) dengan analisis multy dimensional scaling (MDS). Hasil yang diperoleh dari kajian ini adalah luasan mangrove Pulau Nain sebesar 4.40 ha, memiliki dua jenis mangrove yaitu Rhizophora apiculata dan Avicennia marinna masing-masing dari family Avicenniaceae dan  Rhizophoraceae. Indeks nilai penting (INP) jenis tertinggi terlihat pada jenis Rhizophora apiculata (79.64%) sedangkan jenis Avicennia marinna (79.64%). Ekosistem mangrove Pulau Nain dalam kondisi yang baik, tapi secara kuantitas belum optimal sebagai buffer sistem lingkungan pesisir. Status keberlanjutan pengelolaan ekosistem mangrove Pulau Nain menunjukkan angka 46,89 yang berarti status keberlanjutan pengelolaan ekosistem mangrove pulau ini berada dalam kondisi cukup baik. Keterisolasian pulau, luasan mangrove yang kecil, luas pulau yang kecil dan rendahnya kualitas sumberdaya manusia membuat pulau ini memiliki nilai yang kurang baik untuk keberlanjutan pengelolaan ekosistem mangrove Pulau Nain. Pemantauan secara berkala dan strategi pengelolaan yang baik dapat meningkatkan indeks keberlanjutan pengelolaan ekosistem mangrove serta meningkatkan kapasitas lingkungan pesisir Pulau Nain.ABSTRACTThe aims of this study are to analyze the community structure and sustainability of mangrove ecosystem management in Nain Island, Wori District, North Minahasa, North Sulawesi Province. Nain Island is one of the islands rlocated in Bunaken National Park conservation area and   has productive seaweed cultivation area. This study used secondary and primary data. Data required in this study are included dimension data of ecological, socio-economic, and institutional. The analysis that used in this study was RAPMECS (Rapid Appraisal for Mangroves Ecosystem) through multy dimensional scaling (MDS) analysis. The results obtained from this study are mangroves area in Nain Island was 4.40 ha, has two types of mangroves Rhizophora apiculata and Avicennia marinna respectively belong to family Avicenniaceae and Rhizophoraceae. The highest species importance value index (INP) wasfound in Rhizophora apiculata (79.64%) while Avicennia marinna (79.64%). Mangrove ecosystem in Nain Island are in good condition, but in quantity not yet optimal as buffer for coastal environment system. The sustainability status of mangrove ecosystem management of Nain Island shows 46.89 which means that the sustainability status of mangrove ecosystem management of this island is in fair condition. Isolation of island small mangrove areas, small islands and low quality of human resources make this island has a poor value for the sustainability of mangrove ecosystem management. Regular monitoring and good management strategies can improve the sustainability index of mangrove ecosystem management and increase the capacity of the coastal environment of Nain Island.Sitasi: Schaduw J.N.W.

A place in the corner of the Malacca Strait, precisely in Sungai Apit District, Siak Regency, the coastal area of Riau Province, has a role as the transportation routes that connect Bengkalis, Pekanbaru and Batam, as well as ships transit point in Malacca Strait. The area has a very small mangrove cover area but has many local communities who manage mangroves independently, in the midst of dense industrial operations in the area, especially with the Tanjung Buton area which is a development area of a national strategic project. The developments carried out in that place must be carried out in a sustainably, namely balanced in ecological, economic and socio-cultural aspects. Research in that place always discusses only one aspect of the three, moreover what is currently rife is ecotourism, so many researchers have explored the wealth of natural tourism and not a few have discussed its economic benefits. This study aims to analyse these three aspects to produce recommendations for sustainable mangrove management strategies. This research was conducted in 2019-2020 in a descriptive quantitative manner using the Rapid Appraisal method which collaborates the use of several modern technology instruments including remote sensing, transect mapping, and Monte Carlo analysis. The management strategy resulted from a layered analysis that is generally found in separate studies. The results of this study show that the level of sustainability of mangrove ecosystem management in Sungai Apit District is less sustainable. The ecological condition is classified as less sustainable, the economic condition is classified as quite sustainable, while the socio-cultural conditions are classified as unsustainable. The mangrove ecosystem management strategy from this research is the "SO Strategy", that uses Strength to take advantage of Opportunities. The strategy includes increasing wildlife observations as part of educational objects and attractions, as part of the mangrove ecotourism, and development of new ecotourism areas or of existing ecotourism areas by local wisdom concept. Strategy implementation should involve stakeholders and local communities as well as new concept development.
