The mangrove forest area is an ecosystem with highly productive, with a carbon production rate balanced by tropical wet forests. Global warming is increasingly felt by the world's population which is characterized by global climate change. The obvious impact is greatly felt by rising sea levels. This study aims to determine the total surface biomass and carbon stored in mangroves in Mengkapan village, Sungai Apit Sub-district, Siak Regency, Riau. The method used is a 10 x 10 m square block, making 5 transect lines along the coastline and 5 transect lines along the river line. The results of the study found 10 types of mangroves that make up the study area with calculations of the number of mangrove stands found 3236 stands/ha with a total biomass of 61732.74 and carbon absorption of 113.18 tons C/ha.

The former mining area in Tanjungpinang City was found around the Carang River and Senggarang Village. There was sedimentation containing red mud from the rest of the mining activities that covered the mangrove substrate. The impact is expected to affect the life of the surrounding mangroves. One of the dominant species found is Avicennia marina. This study aims to determine the absorption ability of heavy metal A. marina found around the former bauxite mining area of Tanjungpinang City. The study was conducted from April to August 2020. The study was conducted by a survey by sampling the sediment around the A. marina tree and its organs (roots, stems, and leaves) in the laboratory using the Atomic Absorption Spectrophotometer (AAS). The results of the analysis showed that the concentration of Pb in the sediment ranged from 0.2215-0.2711 ppm; Cd concentration ranged from 0.0113-0.0721 ppm; and Cr ranged from 0.0221-0.0633 ppm. The highest average metal concentration value for Pb was in the Carang River (root organ with a value of 2.1691 ppm); Cd metal in Senggarang (stem, 0.0951 ppm); and Cr metal in Senggarang (root, 0.4988 ppm). The phytoaccumulation mechanism of Pb, Cr, and Cd by A. marina is rhizofiltration (TF<1), while the BCF value indicates that A. marina is non-accumulator/low accumulator (BCF < 250 ppm).

In Bandar Alai Kari, Kuantan Tengah Sub-district, Kuantan Singingi Regency, Riau, there is a Buaya Lake. According to the history, the Buaya (crocodiles) Lake, used to be a place for river crocodiles to live (an area of approximately 4.5 ha). To obtain data on the value of the lake's conservation status (ecological value), a rapid assessment method is used using the ECELS index. Observations in the field and with the help of drones to observe the components of the ECELS index assessment, the index value is less than 30. From this value it can be concluded that the Bandar Alai Kari crocodile lake is in a very bad conservation status and needs to be restored

Eco-Forest green open space (GOS) development is one of the ways to achieve sustainable urban development in Pangkalan Kerinci City. The information of structure and composition of the natural tree species growing in the green open space was required as a basis to formulating future rehabilitation strategy. This study aims to analysed the diversity and composition of tree species at the development area of Eco-Forest GOS. The data used in this study was primary data of tree species, dbh, frequency and density. Data collected by field observation using a systematic sampling method. Data analysis was carried out by estimate the diversity parameters including diversity index, richness, and evenness. Species composition assessed by important value index. Spatial interpolation of the diversity index and tree density was carried out by spline interpolation method using ArcGIS 10.7 software. The analysis result shows that the diversity of natural tree species was decreases by increasing the live cycle of tree. There are three dominant species in this location, which Ilexcymosa, Litsea firma, and Stemonurus secundiflorus. Spatial analysis shows that 51.5% of the green space area classified into low diversity and density category, while 13.2% was classified as high diversity and density class. Efforts to achieved the successful of GOS management by use the information of vegetation’s structure and composition as one of the inputs to develop the regeneration and rehabilitation system. At the same time, it is necessary to increases the dimensions of human, institutional and financial management that supports biodiversity conservation in the green open space

Dengue hemorrhagic fever is an infection caused by the dengue virus, the dengue virus is transmitted through the bite of the Aedes aegypti mosquito. The incidence of dengue hemorrhagic fever is influenced by various factors such as environmental sanitation, economy and behavior. This study aims to determine the effect of environmental sanitation and family behavior on the incidence of dengue hemorrhagic fever in Benai District, Kuantan Singingi Regency. This type of research is quantitative with cross sectional design. Data analysis used univariate, bivariate with chi square test and multivariate using binary logistic regression model parameter testing. The results showed that the variables of environmental sanitation and behavior in Benai District, Kuantan Singingi Regency were not optimal so that they were at risk of experiencing dengue fever. Environmental sanitation and behavior variables simultaneously and significantly influence the incidence of dengue hemorrhagic fever in Benai District, Kuantan Singingi Regency. This is related to the large amount of waste that is not properly managed around residents' homes and there are also clean water storage places that are not closed, this condition is due to the lack of public knowledge about the importance of maintaining environmental cleanliness and how to do 3M. Besides that, the attitude of the people who do not care about it also illustrates that the behavior of the people in the area is still lacking.

Bintan Island has a high potential for bauxite mining. Many ex-mining areas have not been reclaimed properly, resulting in erosion and accumulation of heavy metals Pb and Cr which are high in the sediment (red-mud) and deposited in the roots of mangrove forests on the coast of Bintan. Rhizophora mucronata is one of the species that dominates the Bintan mangrove forest. The purpose of this study was to determine the phytoaccumulation of Pb and Cr metals in R. mucronata in the former bauxite mining area ofBintan Island. This research was conducted by survey, digested and analysed using Atomic Absorption Spectrophotometer (AAS). The concentrationof Pb and Cr in the sediment, as well as the roots, stems and leaves of R. mucronata were used for the analysis of phytoaccumulation types. The results of the Pb concentration test were higher than Cr. Based on the sampling location, the concentration of Pb metal accumulation in the sediment is Tembeling <Sei Carang <Wacopek <Senggarang, while Cr metal is Tembeling <Wacopek <Sei Carang <Senggarang. The highest metals accumulation in R. mucronata was found in the roots (Pb = 3,3482 ppm, Cr = 0,7664 ppm), while the leaves (Pb = 1,1076 ppm, Cr = 0,0413 ppm) had the lowest concentration. Based on the type of accumulation, R. mucronata absorbs Pb metal with a rhizofiltration mechanism (TF <1), which means that the roots of R. mucronata effectively translocate Pb as a pollutant to its body from the soil. In addition, the bio-concentration factor (BCF) concentration of R. mucronata <1 indicates the role of R. mucronata as a plant that accumulates very little Pb (low accumulator/non-hyperaccumulator). This adaptation mechanism is important information in the rehabilitation of mangrove areas using R. mucronata, because it can still live and grow in an environment contaminated with Pb metal by absorbing a little Pb from the soil and translocating it effectively in its organs.

Mapping of coastline changes helps in coastal development and monitoring. The city of Dumai, on the east coast of Riau Province, has undergone significant and radical changes caused by the intervention of humans and nature over the past three decades. This study mapped and measured the rate of change of the coastline of Dumai City for 30 years. The Landsat (TM, and OLI) image series, 1990, 1999, 2008, and 2020 became a data source to generate coastlines through on-screen digitization techniques, then to study the temporal behavior of coastlines using the Digital Shoreline Analysis System (DSAS) and geographic information systems to describe the spatial and temporal variations of coastlines. The results showed that the coastline length during the observation ranged from 123,14 to 125,23 km, while the average accretion rate was 1.17 meters per year while the average abrasion rate was 2.04 meters per year. Those rates of change affected coastline expanded to the sea for 60,82 hectares and eroded 760,20 hectares coastline to the land.
