The hydroponic method was tested to increase the efficiency of mangrove planting through effective effectiveness that is lighter and easier to carry in large quantities. This research involves planting mangrove seedlings on a field scale using both methods. The results showed that hydroponic saplings had better effectiveness and efficiency performance than polybag saplings. The advantages of hydroponic saplings in terms of portability and the ability to plant in large quantities can be an attractive alternative in conservation and rehabilitation efforts for mangrove ecosystems. The results of this research indicate that the use of hydroponic saplings in planting can increase effectiveness by 4,512-5,869%, where 1 person can carry 294-385 saplings compared to saplings in small size polybags where 1 person can only carry 7 saplings and can achieve efficiency by 2 %, where 1 Ha only requires 7-9 people compared to saplings in large polybags where 382-384 people have to carry them people, which means it can reduce the number of people 98 % that perform significantly improve from polybag saplings.

The mangrove forest is the ecosystem that can absorb carbon emission from the environment and reserve it in its leaves, stems, and sediment. This research aimed to show the information related to the estimated organic carbon value stored in the mangrove forest’s sediments on Dompak Island. This research was conducted in December 2020 at Dompak Island, Riau Islands. Carbon stock data was evaluated using the LOI (Loss On Ignition) method. The sediment specimens were collected from 5 stations. The result showed that the north station has the highest carbon content, 443.1 tons C/ha, and the south station has the lowest carbon content, 223.65 tons C/ha. The result from the statistic analysis using a one-way ANOVA test between the locations showed that the organic value carbon content in Dompak Island with the significance value of 0.05 stated that there is no real difference.

This study discusses the legal analysis of mangrove damage compensation with the economic valuation in Bintan. This type of research is normative-empirical legal. To provide a deterrent effect and save the environment as well as economic losses to Mangroves. Based on Ministerial Regulation Number 7 of 2014 concerning Environmental Losses Due to Pollution and/or Environmental Damage, describes community losses due to environmental damage, namely those that have an impact on community losses. Economic valuation of compensation due to mangrove destruction. If this value is calculated on the income of fishermen as a whole for all fishermen who are in the mangrove area in Bintan, Economic valuation calculation The income of marginal fishermen who use mangroves in Bintan is Rp200,000 minus Rp70,000 (as operational costs) = Rp130,000,-per day. IDR 130,000 x 20 days (going to sea in a month) = IDR 2,600,000 (monthly income). So that the calculation of the loss of edge fishermen due to mangrove pollution is Rp2,600,000 per month because they cannot go to sea. This is with the consideration that the ship/sampan can be damaged as well as the fishing gear damaged due to being exposed to a large amount of black oil spill. As an ecotourism area in Bintan Regency, it can be calculated using the travel cost method, so that the action of the valuation in 1 month is as follows:

Propagules Rhizophora sp. tends to release after hitting the sediment when exposed to waves, so that by being anchored, propagules can survive until they grow into saplings. Anchors for tubular propagules with a length of 20 cm with diameters of 0.5, 1, 2, and 4 inch were tested, the analysis using one way Anova showed the difference was p<0.001 followed by the tukey post hoc test which showed that the anchor with a length of 20 cm with a diameter of 4 inches had the ability to withstand high the highest with a weight of 9,618.33+96 g. The results of the application in the field showed that an anchor model D with a length of 20 cm with a diameter of 4 inches was able to hold 4 saplings compared to propagules without an anchor.

The shape of the roots, which are like anchors, is what makes mangroves a wave absorber, sediment binder, and so on. One of the functions of mangrove roots is to prevent the release of garbage into the open sea. This is due to the shape of the roots that make garbage snagged (caught) on the sidelines of the roots. The purpose of this study was to analyze the capture of marine debris in the mangrove roots of Rhizopora sp in the Sengarang Besar ecosystem. This research was conducted in December 2021 in the mangrove forest of Senggarang Besar. The method used is the line transect method with 10 Rhizopora sp mangrove trees located on the coast. Then, data analysis on the density of waste caught in the mangrove roots of Rhizopora sp.
