Abstract

Land use and activity around the Rangkui Watershed affect water quality, and plankton have been studied to help manage the river's water quality. In the 2017 dry season, six station points representing land use functions from upstream to downstream were studied. Surface water sampling was carried out during the day with three replicates. Pollution around the Rangkui Watershed affected plankton abundance. Based on saprobity and physicochemical readings, the pollution level ranged from light upstream to heavy downstream. This study found 15 species from 15 families from six phytoplankton classes, that is, Bacillariophyceae, Chlorophyceae, Euglenophyceae, Cyanophyceae, Cryptophyceae, Dinophyceae, and 2 species of zooplankton Eurotatoria, and Branchiopoda. The highest total abundance of phytoplankton and zooplankton was observed upstream of Station 1 (721 ind/L) and gradually decreased downstream, with the exception of the absence of plankton at Station 3. Nitrate had a positive correlation with phytoplankton at different correlation levels, whereas other abiotic environments responded differently to phytoplankton and zooplankton. The water quality is highest upstream, where there are pepper plantations, and gradually decreases as it flows downstream. The station near tin mining activities was the most polluted.

Abstract

Dragonflies are bioindicator insects that are known to be sensitive to the environment and their existence is influenced by habitat conditions. The potential of dragonflies as a bioindicator for the success of reclamation efforts for former tin mining on Bangka Island needs to be studied. This research aims to record the diversity of dragonflies and damselflies in reclaimed land covering an area of ±15.25 ha and aged ±16 years as one component to enrich the criteria for assessing the success of revegetation of ex-tin mining land. This research was conducted in the rainy season, January-March 2023. For three weeks, Schnabel's visual encounter survey (VES) and capture-mark-release-recapture (CMRR) methods were chosen to observe five transect lines, respectively non-revegetation areas, horticultural and fruit revegetation areas, oil palm revegetation areas, kolong with tilapia fish, and kolong with human activities. This research recorded 19 species of dragonflies and 6 species of damselflies, or around 6.5% of the dragonflies and 2.0% of the damselfly species on the island of Sumatra. The most dominant species are Neurothemis fluctuans and Ceriagrion cerinorubellum. The number of species and number of individual dragonflies is thought to be related to the age of reclamation, and has the potential to be an indicator of the success of ex-tin mining reclamation land.

Abstract

This study aims to measure carbon reserves in horticultural plants planted on former tin mining land and compared with horticultural plants on non-mining land in Belinyu District, Bangka Regency. The time and place of this study were carried out from February 2023 to July 2023 in Gunung Pelawan Village, Bukit Ketok Village, Bangka Regency. The research method used was the purposive sampling method. The analysis method used percentage analysis. The results of the study showed that the carbon reserve content of plants plantedon former tin mining land was lower as an adaptation to former tin mining land that experienced drought stress and high light intensity but was not significantly different from plants planted on non-tin mining land. This is thought to be because the care given to plants on former tin mining land was quite good. Future research can be carried out by combining morphological, anatomical and physiological observations, as well as analysis of carbon reserve content in horticultural plants as a response to the former tin mining land environment.
