Abstract

The purpose of this study was to determine the abundance of plankton in the Ogan Ilir regency of South Sumatra. Samples were obtained using a purposive random sampling method with plankton as the main material for measuring abundance and the Shannon Wiener Diversity Index (H), Simpson Dominance Index (C), and plankton abundance index. The results of the study obtained six classes consisting of 15 genera of plankton including Fragielaria, Synedra, Eunotia, Diatom, Fustulia, Oedogonium, Gonium, Chaetophora, Microspora, Allona, Neuplius, Lyngbya, Spirulina, Cyclotella and Dismidium. Diversity value at point 1 (1.75) with medium category, point 2 (3.5) with high category, point 3 (0.75) with the medium category. The diversity value of three points is known to be low in population.

Abstract

Diversity of butterflies in various habitats very diverse, and it is one of them in the region Sumber Clangapand Waduk Selorejo. It has seen from the combination of colors and which wing shape varies. In this, bothregions were chosen because it had been affected by Mount Kelud eruption, which causes damage to thesurrounding area. The purpose of this research is to know the diversity of butterflies (Lepidoptera:Rhopalocera) in the region of Sumber Clangap and Waduk Selorejo, East Java. This research wasconducted on 26-29 January 2019. Sampling has taken by the method of Belt transect along the transectpath randomly with a technique snapshot experiment and a sweeping technique. Based on theobservations obtained 3 of the same family, Nymphalidae, Pieridae, and Papillionidae. The butterflydiversity in Waduk Selorejo belongs to low, whereas in Sumber Clangap are classified by index Shannon-Winner = 0.38 H ' and H ' = 2.47. Found eight types of butterflies from 3 families with a total of 13 speciesand has a value of H ' =2.47.

Abstract

Pandanus species is widely distributed over Bukit Duabelas National Park in Jambi. Suku Anak Dalam (SAD), a local community living in Bukit Duabelas National Park area, use the natural fibers from Pandanus for many necessities, such as plaiting, building materials, and performing mytological rituals. This study aimed to examine floristic composition, distribution patterns, and association of pandanus species in Bukit Duabelas National Park. Sampling was conducted using a striped line, with a plot of 35 sample plots. Dominance of species was calculated using dominant type of important Value Index (IVI) based on the density, frequency, and dominance of sample plot enumeration. Distribution patterns was analyzed using the Morisita Index, while association patterns were measured by Contingency tables and Chi-square tests. Floristic composition was mostly found in the seedling strata consisting of 106 species. The species with highest important value index (IVI=14.53) was Palaquium gutta. There were two species of Pandanus (Benstonea kurzii and Benstonea atrocarpa) were spread in groups and three species of pandanus (Pandanus labyrinthicus, Pandanus furcatus, and Pandanus immersus) were spread evenly. The pandanus species found was associated with Benstonea kurzii was Litsea sp1. This present study suggested that the conservation of pandanus species should be conducted as a piece of rehabilitation of tropical forests in Bukit Duabelas National Park.

Abstract

The aim of this study was to investigate a SETS (Science, environment, technology) based-learning approach for junior high school students on how well SETS based-learning improves thinking skill on the waste management. This study was conducted to 20 students of 7th grade. Data collection were employed by class observation (carried out pre and post test), essay analysis (based on several cognitive indicators such as analyze, evaluate, and create), and learning activities regarding environmental issues. The results showed that SETS based-learning could positively improve students critical thinking in terms of learning process and performance in creativity, motivation, critical thinking. If the number of subjects is increase, SETS based-learning strategy could be more challenging.

Abstract

The shell of snail contains chitin that can be transformed into chitosan through four stages, which are deproteination, demineralization, depigmentation, and deacetylation. Chitosan can be utilized as an antibacterial agent because it has amine groups. In this research, chitosan that prepared from the snail shell will be analyzed using FT-IR spectroscopy to determine the deacetylation degree (DD). The antibacterial activity test result of Staphylococcus aureus will be carried out on chitosan with various concentrations using in-vitro Kirby Bauer method and will be analyzed using One Way ANOVA with confidence level at 95%. The variations concentration of chitosan used is 300, 400, 500, 600, and 700 ppm. The result shows that the deacetylation degree of chitosan is 63.09% and the optimum concentration of chitosan that can inhibit the Staphylococcus aureus bacteria is 500 ppm with diameter inhibition is 34.33 mm.
