Leaf Litter Production

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

Mangrove ecosystem is an important ecosystem in coastal areas which is a habitat for various types of organisms. The existence of mangrove ecosystems in nature is strongly influenced by the availability of mangrove seedlings and seedlings because they are closely related to the secondary succession process in natural habitats. This research was conducted to analyze the potential for regeneration of mangrove seedlings in the coastal area of Dafi Village, Biak Numfor Regency, Papua. Data collection on the potential for regeneration of mangrove seedlings was carried out using the belt transect method. Analysis of species composition and structure of mangrove vegetation at the seedling level used analysis of species density, relative density, species frequency, relative frequency, and important value index. A total of seven mangrove species were found in the coastal area of Dafi Village, Biak Numfor Regency, consisting of Bruguiera gymnorrhiza, Bruguiera cylindrica, Ceriops Tagal, Rhizophora apiculata, Rhizophora mucronata, Rhizophora Stylosa, and Lumnitzera racemoza. The highest species density and relative density values were found in Bruguiera gymnorrizha and Cerops tagal, while the lowest was Rhizophora mucronata and Lumnitzera racemoza. The highest value of species frequency and relative frequency was Bruguiera gymnorrizha, while the lowest was Rhizophora mucronata. The highest Importance Value Index (INP) of mangrove seedlings was found in Ceriops tagal and Bruguiera gymnorrizha, while Rhizophora mucronata had the lowest INP compared to other species.Keywords: Mangrove Ecosystem; Mangrove Regeneration; Important Value Index AbstrakEkosistem mangrove merupakan ekosistem penting di wilayah pesisir yang menjadi habitat bagi berbagai jenis organisme.

This research was conducted to determine the condition of the mangrove ecosystem based on its canopy cover and to determine the types of mollusks (Bivalves and Gastropods) associated with the Benoa Bay mangrove ecosystem. Hemispherical photography is a method for observing mangrove canopy cover and line transect method for mollusks. The composition of mangrove species found in the research location were five species, namely Rhizophora stylosa, Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorrhiza, and Avicennia marina. The percentage of mangrove canopy cover in the Benoa Bay mangrove ecosystem is in a good category (average = 76.59%). There are eight types of mollusks found in the research location. There are two types of bivalves (Polymesoda bengalensis and Gafrarium pectinatum) and six types of gastropods (Nerita balteata, Nerita picea, Neritina turrita, Pila ampullacea, Cassidula aurisfelis, and Littoraria melanostoma). The relationship between the percentage of mangrove canopy cover and abundance of mollusks in the Benoa Bay mangrove ecosystem is very strong (r) of 0.920. The higher the percentage value of mangrove canopy cover, the higher the mollusks abundance.

Ekosistem mangrove merupakan salah satu ekosistem pesisir dengan tingkat produktivitas yang tinggi, sehingga keberadaannya dapat memperkaya kawasan pesisir dan menjaga keseimbangan ekosistem. Penelitian ini bertujuan untuk menjelaskan perubahan luasan dan sebaran ekosistem mangrove dalam kurun waktu 20 tahun, yakni dari tahun 2000 sampai dengan 2020 dan untuk mengetahui kondisi vegetasi ekosistem mangrove di Pulau Tanakeke. Penelitian ini dilakukan pada bulan Januari hingga April 2020 di Pulau Tanakeke. Penentuan lokasi penelitian menggunakan metode purposive sampling. Analisis perubahan luasan ekosistem mangrove dari tahun 2000 sampai 2020 menggunakan metode supervised classification dengan analisis maximum likelihood, sedangkan kondisi vegetasi ekosistem mangrove menggunakan metode analisis indeks nilai penting (INP) dan indeks keanekaragaman jenis. Hasil penelitian menunjukkan bahwa ekosistem mangrove di Pulau Tanakeke dari tahun 2000 sampai 2020 mengalami degradasi seluas -337,41 ha (28,32% dari luas tahun 2000). Pada lokasi penelitian ditemukan 9 jenis mangrove, yaitu Bruguiera gymnorrhiza, Ceriops tagal, Rhizophora stylosa, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, Phemphis acidula, Lumnitzera racemosa dan Ceriops decandra.

The mangrove ecosystem has different density levels per location. It can be influenced by environmental factors or because of human assistance. This research was conducted in Tongke-tongke Village, Sinjai Regency and Pannikiang Island, Barru District. Observations were conducted on three groups, namely groups of trees, stakes, and seedlings. Tree group used plot size 10 m x 10 m, stakes group used plot size 5m x 5m, and the group of seedlings used plot size 1 m x 1m. The result of tree group density will be compared with the standard criteria of mangrove damage of the Minister of Environment to know the criteria and the level of density. The mangrove ecosystem in Tongke-tongke village is overgrown by Rhizophora mucronata and Avicennia sp. and is dominated by R. mucronata with very dense density. In the tree group, R. mucronata has a density of 8020 Ind Ha-1. The mangrove ecosystem in Pannikiang Island is overgrown with Rhizophora apiculata, Rhizophora stylosa, Sonneratia alba, Aegiceras floridum, Ceriops tagal, Avicennia sp., Excoearia agallocha, and Lumnitzera racemosa and has a rare and moderate density. In the tree group, the highest density in C. tagal with a density of 1270 Ind Ha-1 and indicated moderate density. Competition is always there in the ecosystem. The species of this ecosystem is fighting for space and nutrients. Therefore, competition can determine the density of plants in it.

Mangroves are one of the important coastal ecosystems that have various benefits and their uses are carried out by various stakeholders. This study aims to 1) find out and analyze the condition of mangrove resources and community beneficiaries, 2) analyze the roles and functions of each stakeholder, and 3) find out and analyze the form of co-management of mangrove ecosystem management in Lubuk Kertang Village, West Brandan, Langkat Regency. Mangrove vegetation data collection is done using the quadratic transect method; while taking socioeconomic, institutional, and interview data using survey and purposive sampling methods. Data obtained from mangrove vegetation include density, frequency, cover, and mangrove importance index. Stakeholder analysis using a matrix of interests and influences. Research shows there are 5 types of mangroves in Lubuk Kertang Village, namely Avicennia marina, Rhizophora mucronata, Rhizophora apiculata, Rhizophora stylosa and Sonneratia alba. Strategies in the context of expanding mangrove forests are with these types. Stakeholder analysis identified 16 stakeholders who were classified in 4 groups, namely subject, key players, crowd, and by standers. Mangrove management in Lubuk Kertang Village is still in the consultative stage. To improve effectiveness, management is directed at the cooperative level in the co-management spectrum with management strategies.
