Abstract

Knowledge of the diversity of dragonflies (Odonata) is very important for river management which is used for various purposes by humans. This research aims to determine the diversity of Odonata in the waters of Bendungan Lempake, Karang Mumus River and Berambai River Samarinda. Sampling was done by using purposive sampling technique through insect net with transect method along with the river flow, 5 times at each location for one month in the morning and evening. The samples obtained were prepared, stored on triangular paper containing camphor, and identified using entomological guidelines. Environmental temperature, humidity, and acidity of the water are calculated using standard measurement tools. Data is displayed in the form of the number of types and a description of each type. The results showed that 1025 individual dragonflies were found belonging to 22 species and 4 families of Odonata. The diversity index value (H') of dragonflies in the waters of the Bendungan Lempake is 2.83, the Karang Mumus River is 2.52 and the Berambai River is 2.53, which are classified as a medium category. The conclusion of this research is that the waters of Bendungan Lempake, Karang Mumus River, and Berambai River are still supporting as habitat for dragonflies to live and breed.

Abstract

Bioremediation intends to use living organisms to remove or decompose pollutants, using their ability to metabolize or accumulate hazardous substances, thus reducing toxicity. This study aims to compare the removal efficiency of free suspended Chlorella vulgaris and immobilized Chlorella vulgaris. Monoculture isolates of Chlorella vulgaris were cultured in an aqueous medium with KW21 fertilizer for approximately 12 days until reaching the stationary phase. The biomass was harvested, dried, and separated. A ZnCl₂ solution was prepared with 2, 4, and 8 ppm working concentrations. The biosorption efficiency was calculated to evaluate the biosorption capacity. The results indicated that the removal efficiency of free suspended C. vulgaris was 14.73%, 6.76%, and 10.22% for the respective concentrations. Immobilized C. vulgaris exhibited significantly higher removal efficiencies of 73.79%, 77.87%, and 83.80%. This study shows that immobilizeed C. vulgaris have a higher removal efficiency value than free suspended C. vulgaris cells because they can withstand heavy metal toxicity better. This study implicates that the treatment of alginate beads increases the stability and effectiveness of biosorption, and makes this method a preferred approach for heavy metal bioremediation applications in aquatic environments.

Abstract

The Tagur Tinggi Waterfall region is characterized by its verdant and expansive landscape, featuring diverse flora such as trees and grass. This region is optimal for arboreal insects as a habitat. Arboreal insects, which are abundant and readily seen, inhabit the upper branches of trees and travel between trees to facilitate pollination. The abundance of arboreal insects serves as a reliable measure of the overall well-being of an ecosystem. The present study aims to identify the various species of insects that inhabit the trees in the Tagur Tinggi region and calculate the diversity, evenness, and dominance measures for these arboreal insects. This study used the transect approach, wherein samples are gathered bi-daily in the morning and evening. There were a total of 44 bug species belonging to 19 different families and 8 distinct orders. The arboreal insect diversity index (H') was measured to be 3.24 in the morning and 3.14 in the afternoon. Arboreal insects have an evenness index (E) of 0.91 during the morning and 0.87 during the afternoon. Additionally, they have a dominance index (D) of 0.044 in the morning and 0.056 in the afternoon. According to the health index values obtained, it can be inferred that the Tagur Tinggi Waterfall area in Lempake Samarida Village is highly conducive to the survival of arboreal insects. This is due to the well-preserved habitat and abundant vegetation structure that supports the life of arboreal insects.
