Abstract This study aims to determine the level of damage and estimation of rehabilitation value in the Lantebung Mangrove Ecotourism, Makassar City. The sampling technique was carried out using a survey technique with a purposive sampling method. The size of the plots made is 20 m x 50 m with a total of 8 plots. The level of mangrove damage is determined based on land cover and vegetation density. Estimating the value of ecotourism rehabilitation is based on the Regulation of the Director-General of Natural Resources and Ecosystem Conservation P.8/KSDAE/SET/REN.2/10/2017 concerning Standards for Activities and Costs for Conservation of Natural Resources and Ecosystems. The results showed that there were two types of mangrove species, namely Rhizophora mucronate and Avicennia alba. Lantebung Mangrove Ecotourism has a vegetation cover of 82% with a vegetation density of 1,760 individuals/ha, so that the level of damage to mangroves is in a good category. In general, damage to Lantebung Mangrove Ecotourism is caused by converting mangrove forests into fishponds and settlements. The total cost of mangrove forest rehabilitation is IDR. 350,220,000

Mangrove forests are ecosystems that make up coastal areas and river estuaries. The examples of mangrove ecosystems found in Indonesia are in Segara Anakan, Central Java. One of the aquatic biota with the economic value found in the mangrove forest ecosystem is the mud crab (Scylla spp.). The purpose of this study was to assess the distribution of mangrove crabs (Scylla spp.) to the presence of mangrove species in the mouth of the Donan River, Segara Anakan. A sampling of crabs and observations of mangrove vegetation were carried out at five stations spread from the river to the sea. The results showed that there were three types of mangrove crabs caught in the vicinity of the study, namely Scylla tranquebarica, S. olivacea, and S. serrata. The types of mangroves found include Rhizophora apiculata, R. mucronata, Avicennia rumphiana, A. alba, A. officinalis, and Nypa. Regression analysis showed that mangrove density correlated with the abundance of Scylla tranquebarica and Scylla olivacea, but contradicts the abundance of Scylla serrate. PCA analysis showed that the Crab species Scylla tranquebarica and Scylla olivacea were associated with mangroves of Avicennia alba, Avicennia rumphiana, and Rhizophora apiculata. Meanwhile, Scylla serrata crabs are associated with Avicennia officinalis.

Mangrove forest ecosystems are threatened by direct impacts such as cutting and pollution due to agricultural, industrialization and urbanization activities. Mangrove forests are often regarded as unpleasant environments with little intrinsic value.  Mangrove forests perform valued regional and site-specific functions. Mangrove species can take up excessive nutrients and also play a crucial role in creating a favourable environment for a variety of chemical, biological and physical processes that contribute to the inorganic removal and degradation of organic compounds. Among the many mangrove species, Sonneratia alba, Avicennia alba and Rhizophora apiculata have been studied for biomonitoring of toxic heavy metals elements (Fe, Cu, Zn, Pb and Mn) in a wide range of plant tissues (roots and leaves) and sediment composition at  three different locations in Negeri Sembilan, west coast of Malaysia. The results established that there were significant differences between the three mangrove species, locations, plant tissues and sediment samples and their interaction for all the five heavy metals content. The findings revealed that leaf tissues for all species accumulated mostly Fe, Zn, Pb and Cu. Interestingly we noticed that different localities will accumulate different type of heavy metals, for instance R. apiculata leaf tissues were detected with higher concentration of Cu and Pb at Kampung Sungai Sekawang whereas in another two sites were detected with Cu, Fe, Zn and Pb. S. alba indicated that the most heavy metals highly accumulated was Zn followed by Pb and Cu at Pasir Panjang. In this study A. alba showed Zn was highly accumulated in leaf tissues at Pasir Panjang. Thus, those three mangrove species appear to have the greatest potential for use as an effective ecological indicator tools as green application for inorganic contaminants monitoring in mangrove ecosystems.

Mangrove forests are ecosystems located in tidal areas in coastal areas, beaches, and small islands. The area of ​​mangrove forests is decreasing due to the conversion of mangrove forests into fishponds, plantations, and timber exploitation. Mangrove ecosystem rehabilitation activities need to be carried out through planting. Avicennia alba is a pioneer mangrove species that grows in mangrove swamp habitats on sheltered coastal locations, as well as in the saltier parts of the coastline. The objectives of this research is to analyze the effect of planting media and shade intensity on the seedling growth of Avicennia alba. The study used a two-factor experimental design in a complete randomized design. The first factor is planting media and the second one in shade intensity. The results showed that the shading intensity most influenced the growth of Avicennia alba seedlings. The variables affected include height, diameter, number of leaves, total wet weight, and total dry weight. The treatment combination that gave the best results was A2N0, that means the planting medium in the form of a mixture of mud, sand and compost and without shade (0% shade).

Abstract Mangroves are a collection of several species of trees or shrubs that distribute around the coastline and can survive in high salinity environments. Around 60% of mangrove forests in North Sumatra are reported to have been damaged, the main factors of this damage being the mangrove forests conversion into ponds and the expansion of oil palm plantations. Identification of mangrove species is very important in protecting and applying the biodiversity of mangrove forests. Identification of living things has evolved from morphological charcetrization to molecular identification. This study aims to explain the DNA isolation and PCR methods to identify mangrove species in North Sumatra. The results suggested that the rbcL primer used can detect mangrove species that were visualized in the form of DNA bands. The length of DNA fragments of mangrove species Acrosticum aureum ranged 632.0-619.6 bp, species Rhizophora apiculata 619.6-585.8 bp, species Nypa fruticans 600- 592.9 bp, species Avicennia alba 549.1-533.5 bp, species Hibiscus tiliaceus was not detected, and mangrove species Acanthus ilicifolius 480.3 bp.

Mangrove forests in Indonesia play an important role in mitigating climate changes and providing other ecosystem services; however, their extent continues to decline. Information on mangrove community and its carbon stock, especially for Papua, is still limited. This study was conducted to describe vegetation structure and estimate carbon stock in Payumb Coast in Merauke District, Papua. There were three primary mangrove species identified, namely, Avicennia alba, Rhizophora apiculata and Sonneratia alba. Species dominance varied along a gradient of salinity and substrate perpendicular to the shoreline. A. alba is dominant in the closest zone to the shoreline (importance value 205.76%), while R. apiculata is dominant in the farthest zone (importance value 185,35). At the community level, the carbon stock in trees differed significantly between zones (p<0.05), with the highest in the zone dominated by R. apiculata. This study has provided preliminary data on carbon stock estimation at the community level; further studies should be conducted to estimate total carbon stock based on all above- and belowground components. More accurate estimations become important, as it was found that different species could contain significantly different carbon stock; thus producing variation among mangrove communities.
