Abstract

Artisanal and small-scale gold mining (ASGM) can increase the levels of heavy metals in surface water and groundwater sources. This study was conducted to evaluate water quality in Pohuwato Regency, Gorontalo, Indonesia. Sampling was performed at three sites: a reservoir, an irrigation channel, and a well. The concentrations of lead (Pb), cadmium (Cd), iron (Fe), manganese (Mn), and mercury (Hg) were analyzed using Atomic Absorption Spectrophotometry (AAS). The results indicated that Hg concentrations ranged from 0.00883 to 0.01493 mg/L (≈8.8–14.9× above the WHO guideline value of 0.001 mg/L), Mn concentrations ranged from 0.1309 to 0.543 mg/L (≈1.3–5.4× above the WHO guideline value of 0.1 mg/L), while Pb concentrations ranged from 0.0019 to 0.0048 mg/L, Cd concentrations ranged from 0.0002 to 0.0006 mg/L, and Fe concentrations ranged from 0.0728 to 0.101 mg/L, all of which were below the recommended threshold values for drinking water. The findings emphasize the importance of mitigation strategies based on mining governance, strengthening water safety plans, as well as interventions for household water treatment (adsorption/filtration) and risk communication.

Abstract

Lichen are pioneer organisms resulting from symbiosis between mycobionts (fungi) and photobionts (algae or cyanobacteria) that play an important role in maintaining ecosystem balance. This study aims to determine the diversity of lichen species in the Kebun Raya Banua, Banjarbaru City, South Kalimantan Province and to analyze the environmental factors that influence their existence. The study was conducted using an exploratory survey method with a purposive sampling technique at three observation stations, and diversity analysis was calculated using the Shannon–Wiener Index (H'). The results showed that 7 lichen species belonging to 6 families were found, namely Cryptothecia striata, Graphis scripta, Diorygma sticticum, Dirinaria applanata, Phlyctis argena, Lepraria sp., and Bacidia sp., with a total of 110 colonies and a diversity index value of Ĥ = 1.8233 which is included in the moderate diversity category. These values indicate that environmental conditions in the Kebun Raya Banua are still quite stable and support the growth of various types of lichen, with temperature, humidity, soil pH, and light intensity as important factors influencing variations in diversity between observation stations.

Abstract

Ferns (Pteridophyta) are a group of Cryptogamae plants that play an important role in maintaining ecosystem balance and have the potential to be a source of biodiversity learning. This study aims to determine the diversity and evenness of fern species in the Kebun Raya Banua, Banjarbaru City, South Kalimantan Province, and to analyze the environmental factors that influence their existence. The research was conducted using an exploratory survey method with purposive sampling techniques at three observation stations. Diversity analysis was performed using the Shannon–Wiener Index (H’) and the evenness index (E). The results showed that there were 8 species of ferns belonging to 5 families, namely Asplenium nidus, Gleichenia linearis, Nephrolepis biserrata, Lygodium circinnatum, Davallia denticulata, Drynaria quercifolia, Adiantum raddianum, and Microsorum scolopendria, with a total of 62 individuals. The diversity index value H' = 1.894 is classified as moderate, while the evenness index value E = 0.56 indicates that species distribution is also moderate. These values indicate that the environmental conditions at Kebun Raya Banua are still relatively stable and support the growth of various types of ferns, with temperature, humidity, soil pH, and light intensity as important factors that influence diversity variation between observation stations.
