Abstract

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.

Abstract

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

Abstract

Pelalawan District has several sleep peatland areas, which overgrown with grass weeds. This area has the potential to become a sources of beef cattle farming feed in the intensive livestock system. The potential of the beef cattle market is still prospective as a source of protein demanded by the majority peoples. This study aims to valuate and evaluate the potential carrying capacity and economic value of sleep peatlands area as forage provider. This research method was descriptive approach. The data used in this study is secondary data collected from various reliable sources and previous related research. Carrying capacity was expressed by estimate the land's ability to provide cattle feed. Economic analysis is carried out by estimate profit which obtained from the intensive beef cattle farming system. The analysis results shows that sleep peatland areas that potential to supports intensive beef cattle farming around 3,210 ha with carrying capacity = 9,078 cows/year. This carrying capacity was higher than the current beef cattle population around 1,992 cows. The potential economic value reaches IDR 45.56 B/year, which is higher than the current actual economic around IDR 9.99 B. It’s necessary to improve management aspects by integrating the development of intensive cattle farming systems with community-based peatland restoration programs, corporate social responsibility, and SDGs achievement commitments. This requires a solid partnership among stakeholders that will increase the management dimension towards a more sustainable way.

Abstract

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).

Abstract

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
