Abstract

Drosophila melanogaster or commonly known as the fruit fly, is a type of insect found in rotting fruits or vegetables and plants material around the world with a wide distribution. This study aims at determining the LC50 value of eggs, larvae, pupae and the reproductive potential of adult fruit flies (Drosophila melanogaster) exposed to cypermethrin. The method used was an experiment using a completely randomized design (CRD). The data of mortality from toxicity tests were analyzed by ANOVA and Probit test using the SPSS application, while data on reproductive potential parameters were analyzed using the life table method using Ms. Excel. The results of this study showed that the LC50 value of cypermethrin was different at each development stage. The LC50 value from the lowest to the highest successively starts at the egg development stage, which was 1654,824 ppm, then at the egg stage was 3067,192 ppm, the imago stage was 3155,848 ppm and the pupae stage was 3755,014 ppm. The reproductive potential and population rate of D. melanogaster decreased significantly with increasing concentration, lower than the control. The best concentration that was able to reduce the value of the net reproduction rate (R0) and the ability of the population to multiply (λ) was 266.6 ppm with an average value of 0.22 and 0.86, respectively. Further, the best concentration in reducing the average life period (T) and the population reproductive potential (rm) were a concentration of 250.0 ppm with an average value of each parameter of 9.64 and -0.03.

Abstract

Ceriops tagal is a major mangrove species that plays an important role in the mangrove ecosystem. Ceriops tagal is one type of mangrove that has benefits for various marine organisms such as fish, shrimp, nematodes, etc also can maintain the stability of the mangrove ecosystem. In rehabilitation, it is necessary to have a nursery. The addition of husk and husk charcoal to the nursery media can increase the absorption space for water, air, and plant nutrients. The research aims to (1) determine the effect of differences in nursery media with a mixture of husk and husk charcoal on mud media; (2) determine which nursery media has the best effect on biomass and chlorophyll content of C. tagal mangroves. This research started from planting the propagules of C. tagal in different composition growing media with husk and husk charcoal then calculated with ANOVA test 5% and 1% of the biomass in root, stem, leaves, and hypocotyl also chlorophyll content in leaves of C. tagal organ. Then proceed with the honest significant difference test 5% for the wet biomass of root, dry biomass of stem, root, and wet also dry biomass hypocotyl of C. tagal. Research obtained that modification of nursery media with husk and husk charcoal can increase dry biomass of root and stem also wet and dry biomass of hypocotyl in C. tagal organs. The media best media for increase the biomass of the C. tagal in each organ was media 5 (composed of mud + husk charcoal in ratio 2:1) and media 6 (composed of mud + husk + husk charcoal in ratio 1:1:1). The increasing dry biomass of root and stem also wet and dry biomass of hypocotyl are also affected by environmental factors such as pH content in the medium.

Abstract

Phytoplankton has an important role in an aquatic ecosystem because it is autotrophic and also a source of natural food for fish. Phytoplankton will interact with other biotic factors to form a community structure that is useful for the sustainability of the ecosystem Therefore, this research is needed to determine the phytoplankton community structure in Cacaban Reservoir because the community structure can shows the water conditions. The purpose of this reserch was to determine the composition, abundance, and diversity of phytoplankton at each station and the most dominant type of phytoplankton in Cacaban Reservoir. The result showed that there are 18 species of phytoplankton in Cacaban Reservoir. The four phytoplankton divisions found were Chlorophyta with 8 species, Bacillariophyta with 5 species, Cyanophyta with 3 species, and Charophyta with 2 species. The abundance is in the medium category, with the abundance of Chlorella sp. the highest at stations I, III and IV; and Microcystis sp. at stations II and V. The diversity index ranges between 1,227-1,766 and was in the low category which indicates low community stability. The dominance index range between 0,648-0,791 and was in the high category. The dominant phytoplankton in the Cacaban Reservoir is from the Chlorophyta division, which is also a type favored by fish.

Abstract

Coprinus comatus or chicken drumstick mushrooms has potential as antioxidant and antidiabetic. Hyperglycemia in people with diabetes mellitus causes an increase in Reactive Oxygen Species (ROS). Pancreatic β cells have less antioxidants than other organs. This causes oxidative stress which triggers a chain reaction of lipid peroxidation which damages the kidneys and disturbs the glomerular filtration rate. Impaired glomerular filtration rate is characterized by increased levels of urea and creatinine. Flavonoids in C. comatus are able to donate H + and stop lipid peroxidation reactions in the kidneys, so that urea and creatinine levels decrease.This study aims to determine the effect of C. comatus ethyl acetate extract on blood urea and creatinine levels in diabetic rats and to determine the effective dose of C. comatus ethyl acetate extract on blood urea and creatinine levels in diabetic rats. This study used an experimental method based on a completely randomized design (CRD). The data obtained from the measurement of urea and creatinine levels were analyzed using the one way Anova statistical test at the 95% confidence level and followed by Duncan's test at an error rate of 5%. The results of this study indicated that the ethyl acetate extract of C. comatus affected the blood urea and creatinine levels of diabetic rats. C. comatus extract at a dose of 500 mg/kgBW is an effective dose that has an effect on reducing levels of blood urea and creatinine in the amount of 16,66 ± 0,00 mg/dL dan 0,40 ± 0,12 mg/dL.

Abstract

Coprophilous fungi or dung loving fungi are a group of fungi adapted to life on dung and fecal pellets of herbivorous animals. Coprophilous fungi contain psychotropic compounds. Psychotropics compounds are substances or drugs, both natural and synthetic, not narcotics, which have psychoactive properties through a selective influence on the central nervous system which causes distinctive changes in mental activity and behavior. Chemical Spot Test still remain an important tool for the preliminary identification of illicit drugs and other psychotropic compound in spite of developments in instrumental technology and the increased portability of this technology which enables its use in the field. Banyumas Regency is a very potential area as a habitat for coprophilous fungi, specifically in Baturraden District because there are many cattle farms where the dung is where the fungi grow, also the climate is suitable for fungal growth. make an inventory and identify the coprophilous fungi found in District of Baturraden Banyumas Regency and to detect the presence of psychotropic compound in the fungi. The research will be conducted using purposive random sampling and Color Test or Chemical Spot Test analysis. The obtained data is analyzed descriptively by comparing with Atlas of The Munsell Color System. This research obtained seven genera of coprophilous fungi i.e: Coprinellus sp., Coprinopsis sp., Entoloma sp., Gymnopus sp., Lepiota sp., Parasola sp. and Stropharia sp. that discovered in two cattle farms in Baturraden District.
