The use of mangrove forests in Kuala Bubon, in general, gives priority to economic functions rather than ecological functions. If this is not managed as soon as possible, damage to mangrove forests will become more extensive. In general, there are two factors causing damage to the mangrove forests that occurred in the Kuala Bubon, namely human factors and natural factors. The objective of this study is to determine the use of mangrove forests for the life of coastal communities and the participation of communities in the preservation of mangroves. The method of data collection using survey methods is carried out from descriptive and quantitative way. Perception and community participation were analyzed using quantitative descriptive methods. The method used to measure people's perception is the Likert scale method. The results of the study showed that the use of mangroves for the life of coastal communities was still in the middle category, based on the categorization of the data, revealed that the value of using the mangrove (1,113) is one of the criteria that approaches high levels. This shows that the use of mangroves in the village of Kuala Bubon, Samatiga district, West Aceh Regency is already good, although there is still no specific sanction for people who cut illegally. Community participation in the conservation of mangroves can improve the lives of coastal communities is still insufficient when, based on the calculation of the categorization of data obtained, the value of the community participation of 1,498 is among the average criteria.

The decline in mangrove vegetation density and the area of mangrove forests in the coastal province of Riau occurred due to the logging of mangrove forests and the conversion of mangrove forests into other uses such as industrial estates. This study aims to collect a database of mangrove ecosystems which includes the ecological structure of R. apiculata in Riau Province. Collecting data of mangrove vegetation condition was done by transect line and plot. The line transect was drawn from the reference point (the outer mangrove stand) with the direction perpendicular to the coastline to the mainland and made plots according to the category. The results showed that the population of R. apiculata was found in large numbers at Station 3 (350 ind) and a small/small amount was found at Station 1 (137 ind). In addition, Stations 1, 2 and 4 have only one grouping population of R. apiculata based on the Bhattacharya method, while Station 3 has two groupings. Furthermore, the highest R. apiculata density for tree category was obtained at Station 4 (1433.33 ind/m2), saplings category at Station 3 (10488.89 ind/m2) and seedlings category at Station 4 (3666667 ind/m2). Furthermore the water temperature ranged from 28.3 – 30.7°C, salinity 27.3 – 31.3, pH 7.3 – 7.9, DO 5.2 – 6.4 and redox potential ranged from 102 – 124 mV. Based on the standard criteria and guidelines for determining mangrove damage according to the Decree of the Minister of Environment No. 201 of 2004, the population density of R. apiculata at the research location is still classified as medium and refers to the Decree of the State Minister of Environment No. 51 of 2004 concerning Sea Water Quality Standards for Marine Biota, as a whole the range of measured water quality parameters is still within tolerance limits for life mangroves.

This study aims to collect a database of mangrove ecosystems which includes the ecological structure of R. apiculata in Riau Province. Collecting data of mangrove vegetation condition was done by transect line and plot. The line transect was drawn from the reference point (the outer mangrove stand) with the direction perpendicular to the coastline to the mainland and made plots according to the category. The results showed that the population of R. apiculata was found in large numbers at Station 3 (350 ind) and a small/small amount was found at Station 1 (137 ind). In addition, Stations 1, 2 and 4 have only one grouping population of R. apiculata based on the Bhattacharya method, while Station 3 has two groupings.
