Abstract

Gafrarium tumidum species on Ambon Island can be found in the mangrove ecosystem areas of Rutong Country and Waai Country, when sea water conditions recede the people of Rutong Country and Waai Country often use G. tumidum species for consumption. The purpose of this study is to determine the density and distribution pattern of G. tumidum, know the habitat conditions and know the relationship between the abundance of G. tumidum and its habitat characteristics. The process of collecting data on mangrove conditions, Gafrarium tumidum species and environmental parameters was carried out using the Stratified Random Sampling method. Data collection of mangrove canopy cover was carried out using a simple Hemispherical Photography method. The highest density of G. tumidum is found in Waai Country with a distribution pattern of G. tumidum in Rutong Country has a uniform distribution pattern and in Waai Country has a clustered distribution pattern. The habitat conditions of G. tumidum can be explained that, only Sonneratia alba species found at all observation stations in both locations with overall mangrove conditions in both locations having sparse density conditions and moderate canopy cover. Salinity conditions at both locations vary. Then the substrate condition in both locations there are two types of substrate, namely sandy stone and rocky sand with the most dominant type of substrate in both locations, namely sandy stone. The relationship between the abundance of G. tumidum and habitat characteristics in each location has an inverse or negatively correlated relationship and the abundance of G. tumidum is more likely to cluster at Rutong 1 and Waai 5 stations.

Abstract

Mangrove merupakan tumbuhan yang memiliki peranan yang penting baik secara fisik, ekonomi, dan ekologi. Salah satu fungsi ekologinya adalah penyimpanan karbon. Mangrove yang dikategorikan sebagai ekosistem lahan basah yang dapat menyimpan karbon 800 – 1.200 ton/ha. Penelitian tentang estimasi simpanan karbon ini sangat diperlukan untuk menunjang perbaikan iklim dunia yang saat ini dilanda pemanasan global. Pengambilan sampel dilakukan bulan Maret – April 2019. Metode yang digunakan adalah purposive sampling dan eksploratif yang dilakukan pada empat stasiun dengan kondisi mangrove yang berbeda-beda. Setiap stasiun penelitian dibagi menjadi tiga plot untuk menghitung nilai biomassa tegakan menggunakan rumus allometrik dalam mengestimasi simpanan karbon pada tegakan. Kemudian data karbon substrat didapat dari masing-masing plot kemudian dilakukan analisis kandungan bahan organik pada substrat dengan metode LOI (Loss on Ignition). Berdasakan hasil penelitian di Desa Betahwalang didapatkan nilai simpanan karbon pada tegakan vegetasi mangrove sebesar 1.684,24 ton/ha dan nilai simpanan karbon substrat mangrove sebesar 96,26 ton/ha.Mangrove is a plant that has an important role in both physical, economic, and ecology.

Abstract

ABSTRAKEkosistem mangrove memiliki peran yang sangat penting  dalam menjaga kestabilan lingkungan baik di perairan laut maupun pada area terestrial, beberapa peran ekosistem mangrove untuk menjaga kestabilan lingkungan perairan laut yaitu, mangrove berperan penting dalam mendukung peningkatan produktivitas suatu  perairan, mangrove berperan sebagai habitat bagi beberapa organisme perairan dan juga sebagai area penyaring bahan-bahan pencemar yang berasal dari aktivitas antropogenik di wilayah terestrial. Berdasarkan peranan-peranan tersebut maka ekosistem mangrove sangat perlu dijaga dan dilestarikan, sehingga pemberian pemahaman dan pengetahuan melalui kegiatan penyuluhan terkait arti penting perlindungan ekosistem mangrove dan peran generasi muda dalam melindunginya perlu dilakukan terhadap siswa-siswi sekolah menengah atas yang merupakan generasi penerus bangsa dan merupakan generasi yang menjadi penentu masa depan bangsa ke depan. Metode yang digunakan, yaitu dalam bentuk penyuluhan dan pengetahuan penggunaan aplikasi Monmang 2.0 dalam mendeteksi kondisi kesehatan mangrove, serta kegiatan ini diikuti oleh 40 siswa. Berdasarkan kegiatan penyuluhan ini diharapkan dapat menimbulkan kebiasaan baik dari para siswa-siswi dalam menjaga keberlangsungan fungsi ekosistem pesisir khususnya ekosistem mangrove di Pulau Ambon, sehingga dapat berdampak positif yang bersifat berkelanjutan bagi masyarakat dan lingkungan. Kemudian dari kegiatan ini juga dapat memberikan masukan terhadap pihak sekolah dan pengurus OSIS, sehingga salah satu kegiatan ekstra kurikuler sekolah nantinya dapat berupa kegiatan yang merujuk pada pelestarian lingkungan, seperti kegiatan penanaman mangrove dan aksi bersih pantai.  Kata kunci: peran; mangrove;  generasi muda. ABSTRACTThe mangrove ecosystem is vital to maintaining environmental stability in marine and terrestrial areas. Several roles of the mangrove ecosystem are to maintain the stability of the marine environment; namely, mangroves play an essential role in supporting increased productivity of waters, and mangroves act as a habitat for several aquatic organisms. Moreover, it is a filter area for pollutants from anthropogenic activities in terrestrial areas. Based on these roles, the mangrove ecosystem needs to be protected and preserved, so providing understanding and knowledge through outreach activities regarding the importance of protecting the mangrove ecosystem and the role of the younger generation in protecting it needs to be carried out for high school students who are the nation's next generation and are the generation that will determine the future of the nation in the future. The method used was counseling and knowledge on using the Monmang 2.0 application in detecting mangrove health conditions, and 40 students attended this activity. Based on this outreach activity, it is hoped that it can create good habits among students in maintaining the sustainability of the function of coastal ecosystems, especially the mangrove ecosystem on Ambon Island so that it can have a positive, sustainable impact on society and the environment. Then, this activity can also provide input to the school and OSIS administrators so that one of the school's extra-curricular activities can later be an activity that refers to environmental preservation, such as mangrove planting activities and beach clean-up activities. Keywords: role; mangrove; young generation.

Abstract

The canopy closure within Waiheru Village's mangrove community is crucial in shielding residential areas from robust winds and providing shade for associated aquatic organisms, thereby mitigating the effects of direct sunlight. Furthermore, the shading provided by the mangrove canopy contributes to the area's carrying capacity for developing mangrove-based ecotourism. This study aims to investigate the distribution of mangrove species, substrate distribution, and the condition of the mangrove canopy closure. Stratified Random Sampling was employed for the data collection on mangroves and substrates, while the Hemispherical Photography method was utilized to gather canopy cover data. The analysis revealed the presence of 11 mangrove species from seven different families, with Rhizophora mucronata exhibiting the most extensive growth distribution compared to other species. Two substrate types, sandy and sandy mud, were also identified. The mangrove canopy closure in Waiheru Village remains in favorable condition, as most observation stations demonstrate a high proportion of dense and moderate canopy closure.

Abstract

Mangrove canopy cover plays an important role in maintaining and protecting environmental stability in coastal areas, namely as a habitat for various terrestrial species and as protection from direct exposure to ultraviolet light on associated aquatic organisms. Mangrove canopy cover is important in protecting coastal areas from strong winds. This research aims to analyze the condition of the mangrove area, the condition of canopy cover based on the NDVI value and the percentage value of canopy closure, and the relationship between NDVI and percentage canopy closure. Sentinel-2B image data was processed using QGIS 3.28.13 and ArcGIS 10.8 software. Maximum likelihood classification is used to separate mangrove delineation from other objects, and an accuracy test is carried out using a confusion matrix to test the accuracy of the classification results. Observations were determined using a purposive sampling method, and canopy closure data was collected using a simple hemispherical photography method. The condition of canopy cover was analyzed based on NDVI calculations and calculation of the percentage of canopy closure, which was carried out using image-j software and Microsoft Excel 2010. The analysis showed that ten types of mangroves included seven families and eight genera with a mangrove area of 21.66 ha. 62.70% of the mangrove area has a canopy cover condition based on the NDVI value, which is very dense. Also, 50% of observation stations have a canopy cover condition based on the canopy cover percentage value, which is still classified as dense. The correlation between the NDVI value and the percentage value of mangrove canopy cover has a unidirectional relationship and a very strong relationship with a correlation coefficient r of 0.949.  Tutupan Kanopi mangrove sangat berperan penting dalam menjaga dan melindungi kestabilan lingkungan pada wilayah pesisir, yaitu sebagai habitat bagi berbagai macam spesies terestrial dan juga sebagai pelindung dari terpaan sinar ultraviolet secara langsung terhadap organisme perairan yang berasosiasi, tutupan kanopi mangrove juga sangat berperan penting dalam menjaga dan melindungi wilayah pesisir dari terpaan angin kencang. Penelitian ini bertujuan untuk menganalisis kondisi luasan mangrove, kondisi tutupan kanopi berdasarkan nilai NDVI dan nilai persentase tutupan tajuk mangrove, serta menganalisis hubungan NDVI dan persentase tutupan tajuk.
