Mangrove forests on Tanakeke Island provide many benefits, both direct and indirect benefits. All the benefits received/enjoyed by the community so far have never been calculated/valued in money so sometimes the community does not realize how much value is actually given by this mangrove forest and how much it contributes to their income. Resource economic valuation is a method used to estimate the monetary value of goods and services provided by mangrove forest resources. The purpose of this study was to determine the total economic value of the benefits of mangrove forests on Tanakeke Island. The total economic value of the benefits of mangrove forests is derived from the value of direct benefits (tree, firewood, charcoal, seaweed stake, fish and mangrove crabs), indirect benefits (anchoring abrasion and intrusion), optional benefits, existence benefits and inheritance benefits. Based on the results of calculations, the total economic value of mangrove forests on Tanakeke Island is Rp73,563,108,250.00/year or  Rp127,492,388.00/ha/year. Direct benefits provide the greatest value of Rp44,173,560,000.00/year (60.05%), then indirect benefits of Rp14,257,696,532.00/year (19.38%), the benefit of being Rp10,597,566,668.00/year (14.41%), the inheritance benefit of Rp4,417,356,000/year (6.00%) and optional benefits of Rp116,929,050/year (0.16%).

Coastal communities are dependent on the resources available in mangrove ecosystems. The loss of these ecosystems would mean local, national and global welfare losses. Healthy mangrove ecosystems were related with integrated ecological and economical processes by local people. In the present study, uses of mangroves, products and the fishery status of local areas have been studied. The mangrove forests from the study areas provide charcoal, firewood, food and some medicinal plants for local people. To assess the economic value of the regions, the local people from three villages who lived in and near the mangrove forest were questioned and documented. The households studied were categorized into three groups such as poor, middle and rich class and then their monthly income and kinds of jobs studied. The products and works based on mangrove forest and water ways of study areas were the production of Nipa thatches, dried fishes, dried shrimp, nga-pi, pickled shrimp, shrimp sauce and charcoals.

Mangrove ecosystem is a very important resource for the continuity of community life in coastal areas. Mangrove ecosystem in the coastal area of downstream Rokan district has decreased mangrove area because it is used as a pond area to reduce the production of mangrove litter as an ecological function that can be a carrying capacity of coastal capture fisheries. However, the use of coastal areas as pond areas provides economic benefits for aquaculture. This study aims to calculate the economic value of the Rokan Hilir Coastal mangrove ecosystem. This research was conducted in March-April 2019 in the survey method. Analysis to calculate the total economic value of the mangrove ecosystem is NET=ML+MTL+MP. The results showed the total economic benefit value of Rokan Hilir mangrove forest reached IDR 98.697.950.594 / year was a direct benefit value of IDR 701,425,106 / year, indirect benefits were obtained at IDR 94,606,056,000 / year, and the optional benefits reached IDR 3,512,126,520 / year. Mangrove ecosystems are ecosystems that provide many benefits to the Rokan Hilir Coastal community, so this ecosystem is highly expected to be sustainable.

ABSTRACTMangrove forests are coastal intertidal ecosystems, characterized by mangrove trees growing in slow moving saline waters, that constitute a large portion of the coastline in the tropical and subtropical regions. The dynamic water regime created by the tides results in different microhabitats in which microbial communities play an essential role in the functioning and maintenance of the mangrove ecosystem. However, little is known about the diversity of taxa within these micro-habitats and their functional roles, as only a small fraction of these organisms can be cultured in the laboratory. In this study, we characterized the microbial community present in three distinct regions of mangrove sediments from the Serinhaém estuary, part of the Atlantic Forest biome within the Environmental Protection Area of Pratigi. We sampled sediments from regions below the tidal waterline (submerged), intertidal regions (intertidal), and regions above the tidal waterline (seco). More than 85% of all the sequences in the samples belonged to 6 of 42 identified phyla: Proteobacteria (30.6%), Firmicutes (30%), Chloroflexi (8.7%), Planctomycetes (5.7%), Crenarchaeota (5.4%) and Actinobacteria (5.3%). Diversity indices show that the submerged regions of the mangrove forest exhibit the greatest diversity and richness relative to the other regions. Notably, the intertidal region has the least diversity, suggesting that the dynamics of environmental variables in this region has an important influence on microbial diversity. Furthermore, distance metrics indicate that submerged sediments are more homogeneous while the seco region exhibits greater variability between locations. Finally, we found that the most abundant microbial families in the sediments are associated with nutrient cycling consistent with the essential role of the microbiome in maintaining the health of the mangrove ecology.
