Abstract

Yogyakarta is the second-largest producer of plastic waste in Indonesia. Plastic waste in the waters can be degraded into microplastics that can enter the body of a fish. This study aimed to determine the presence of microplastics in the digestive tract of several species of fish in Pantai Baron, Yogyakarta, Indonesia. This research was an exploratory research conducted in April-September 2019 at Pantai Baron, Yogyakarta. Two species of each pelagic and demersal fish samples were taken by buying fish caught by fishermen. The digestive tract of fish was extracted with 10% KOH, filtered, then visual identification. Microplastic types were estimated by FT-IR spectrometry. The amount of microplastic of all fishes was done by Kruskal-Wallis test while the number of microplastics of the two categories of fish was compared with the Mann-Whitney test. A correlation analysis was carried out between the length of the fish, the weight of the digestive tract, and the number of microplastics found. Microplastic shape, color, size, and type data were analyzed descriptively. A total of 78 of the 80 (97.50%) fish from four species studied contained microplastics with a total number as many as 3,651 (mean 45.60 ± 44.31 microplastic/individual). About 100% of pelagic fish samples contained microplastics, while only 95% of demersal fish samples contained microplastics. Mann-Whitney test results showed the number of microplastic/ individual was significantly different between pelagic and demersal fish (p <0.05). The most dominant shape of microplastic was fiber (53.14%), film (36.97%) and fragments (9.89%). The type of polymers detected was polyamide. The results showed that pelagic fish swallowed more microplastics than demersal fish did because of the microplastic nature that is lightweight and floats. Microplastic characteristic data can be used to estimate the main source of microplastic pollution in Pantai Baron so it can be managed appropriately.

Abstract

 Chicken meat and shrimp are perishable food materials. Giving natural preservatives is one way to extend the storage time of food. This study aimed to know the potential of papaya seed powder varieties of ‘Bangkok’ and ‘California’ as preservatives. The sample consisted of two varieties of papaya seed powder with concentrations of 2,4,6 and 8 g. Storage time for chicken meat and shrimp was the third days. Parameters measured were total bacterial colonies, pH va-lues, and organoleptic characteristics (color, aroma and texture) of fresh chicken meat and shrimp. The result showed papaya seed pow-der influences the quality of chicken meat and shrimp. fresh chicken meat and shrimp with papaya seed powder varieties ‘Bangkok’ and ‘California’ had a lower total bacterial colony as much as 9 x 105 until 1x106 compared to control which were 4.2 x 107 - 1.87 x 107. Organoleptic result of chicken meat and shrimp with the treatment of papaya seed powder and stored for three days continue to decrease in term of color, aroma and texture. In chicken meat, the decrease in bacterial growth was still within the limits of microorganism con-tamination quality in animal-based food. However, the same con-centrations of papaya seed powder in the shrimp have not been able to reduce bacterial growth until the limit permitted by SNI.

Abstract

The natural occurrence of solar eclipses can cause various impact on bird species. The purpose of this study was to examine the effect of the partial solar eclipses on changes in behavior of three species of Ardeidae in the Rancabayawak, Gedebage, Bandung, West Java. The research method used was qualitative which direct observation sampling technique was applied.  The results of study showed that three bird species of Ardeidae namely Javan Pond-Heron (Ardeola speciosa Horsfield 1821), Buffalo Egret (Bubulcus ibis Linnaeus 1758, and small egrets (Egretta garzetta Linnaeus 1766) with total population 566 individuals were recorded in the resting and breeding place of bamboo trees and surrounding area of Rancabayawak during the partial solar eclipse.The behavior of these tree bird species, including sound of chicks, sunbathing, preening the feather, and flying of individual adults went out the resting and breeding place of bamboo trees observed tend to be normal before occurring the partial solar eclipse. During the partial solar eclipse, however, the sound of the chick stopped for a second. Some individual adult birds stopped involve in preening their feather. While, some adult individual birds were flying go back to the nest of bamboo trees that may be assumed it has already late afternoon due to dark of sun shine. Implication of this research have been considered to be very important for contributing the scientific knowledge on bird behavior changes caused by natural phenomena of the partial solar eclipse.

Abstract

The COVID-19 has spread worldwide and become an international pandemic. The promising target for drug discovery of COVID-19 was SARS-CoV-2 Main Protease (Mpro), that has been successfully crystallized along with its inhibitor. The discovery of peptide-based inhibitors may present better options than small molecules for inhibitor SARS-CoV-2 Mpro. Natural compounds have such a wide potential and still few explored, Zizyphus spina-christi is one of the medicinal plants that have many pharmacological activities and contains a peptide compound from alkaloids class, i.e. cyclopeptide alkaloids, that is interesting to explore as SARS-CoV-2 Mpro inhibitor. The compound structure was drawn and optimized using density functional theory 3-21G method. The protein chosen was the high resolution of SARS-CoV-2 MPro receptor (1.45 Å) with PDB ID: 6WNP, in complex with boceprevir. Molecular docking simulation was performed using Autodock4 with 100 numbers of GA run, the validation methods assessed by RMSD calculation. Furthermore, the prediction of pharmacological activity spectra was carried out using the PASS Prediction server. The results showed RMSD value was 1.98 Å, this docking method was valid. The binding energy of all compounds showed better results than the native ligand (Boceprevir). The in silico PASS prediction results indicated that all compounds showed antiviral activity. Some compounds showed protease inhibitory activity, i.e Ambiphibine-H, Franganine, and Mauritine-A, and the highest Pa (Predicted activity) value showed by Mauritine-A compounds. It can be concluded that the cyclopeptide compounds of Zizyphus spina-christi were indicated to have a potential as COVID-19 therapy targeting SARS-CoV-2 Mpro.

Abstract

   Some small islands in Balikpapan Bay consist of dry land which may have different vegetation structure and composition. Our study was the first to uncover vegetation conditions and soil proper-ties of dry land on small islands in Balikpapan Bay, which has never been conducted before. The research was carried out on Kalawasan and Karantina islands. Information on vegetation was obtained by applying a line transect method. Data on soil properties were col-lected by setting up 3 sampling plots in each transect of vegetation. Parameters used for analysing vegetation including relative densi-ty, relative frequency, relative dominance, Shannon-Wiener diversi-ty index, evenness index, and similarity index. Meanwhile, data on soils were analysed descriptively. Trees on Kalawasan island were comprised of 241 individuals belonging to 21 species. There were 61 individuals (22 species) of trees on Karantina island. The diver-sity index of trees on Kalawasan and Karantina island was 2.55 and 2.72, respectively. The tree evenness index was 0.84 on Kalawasan island and 0.88 on Karantina island. The index of similarity for trees between the two islands was 0.21. Furthermore, the soil character-istics on Kalawasan and Karantina islands showed similarities. In general, soil in Kalawasan and Karantina islands could be catego-rised as marginal soil which was common in East Kalimantan. Con-sidering the rapid loss of tropical forests in the mainland of Kali-mantan indicates that the small islands of Balikpapan Bay play an important role in future biodiversity conservation in East Kalimantan.

Abstract

 The Biological Nitrogen Fixing (BNF) cyanobacteria can reduce atmospheric nitrogen into ammonium. This ability makes BNF cyanobacteria a potential eco-friendly N-source for soil-planted pad-dy. Apart from a few success stories of BNF cyanobacteria applica-tion in the rice field, its role as an ammonium producer is still an open question. There is also a possibility that indeed cyanobacteria biomass which provides nitrogen through the biological decomposing process. This study aimed to analyze the influence of three strains BNF cyanobacteria on paddy grown in the Deep-Water Culture (DWC) hydroponic system. Yoshida Nutrient Solution was used as a growth medium with the application of 0, 45.7, and 91.4 gL-1 of ammonium nitrate (NH4NO3) with five replications. The result showed that inter-action between cyanobacteria and nitrogen significantly influenced the total nitrogen of paddy plant, but not the paddy plant height, the num-ber of tillers, and biomass. Cyanobacterial filaments were found most-ly attached to the paddy root rather than floated in the DWC system. Paddy treated with cyanobacteria had more lateral root than control. The result suggested that cyanobacteria support paddy growth indi-rectly through nitrogen deposition in plant tissue and root development.

Abstract

Bryophytes are a major component of the ecosystem in Indonesia. Due to their sensitiveness, the abundance and diversity of bryophytes in an ecosystem are influenced by environmental conditions. This study aimed to determine the diversity of bryophytes based on ecological parameters in the village of Blumah Kecaman Plantungan, Kendal Regency which is directly adjacent to the Mount Prau protected forest, Central Java. The data collection method used was the exploratory method and the descriptive exploratory method with survey techniques. Observation was carried out by exploring an area of  3 kilometers, every 1 km distance. An observation station was made consisting of station 1 Jiwan hamlet, station 2 Garung, and station 3 at Cengkek and Gondan springs. The specimens were identified based on taxonomic literature. Each species was collected as a specimen for further identification in the laboratory. Abiotic environment parameters such as temperature, humidity, altitude, light intensity, pH and slope were observed. The results showed that Blumah village still has high plant diversity, especially bryophytes. The more humid, the higher the place, the lower the temperature and light intensity, the more species diversity. Based on the identification results, 21 species were recorded, which includes 15 species of mosses, 4 species of liverworts, and 2 species of hornworts. The index value of bryophyte species diversity was in the medium category, and the index value of species richness and species dominance were at low levels.

Abstract

Coffee fruit skin contains antioxidant compounds that can repair damaged tissues, especially those of reproductive or-gans. This study was designed to assess to what extent the metha-nolic extract of coffee fruit skin affected sperm characteristics and testicular histology in mice receiving 15% ethanol for 15 days. It used 25 male mice aged four months and employed a completely randomized design with two controls (K) and three treatments (P), namely K1 (without ethanol), K2 (15% ethanol), P1 (15% ethanol and the methanolic extract of coffee fruit skin, or MECS, at 125 mg/ kg BW), P2 (15% ethanol and MECS 250 mg/kg BW), and P3 (15% ethanol and MECS 500 mg/kg BW). These treatments were administered orally with a 1 mL disposable syringe for 15 days. The parameters observed were sperm characteristics (viability, morphology, and sperm count) and the microscopic structure of the testicles (lu-men area, diameter, and area of seminiferous tubules). These data were then analyzed using the one-way ANOVA, continued with the LSD and Duncan’s tests (P <0.05). The results showed that P2 (250 mg/kg BW) substantially improved sperm count (86.5x105±1.73 cells/ mL), sperm viability (87.26±0.05%), and the proportion of normal sperm morphology (93.33±0.004%) of mice with 15% ethanol-in-duced sperm damages. Testicular histology also confirmed improve-ments in spermatogenic cells, as evident from the lumen, diameter, and area seminiferous tubules after receiving P1 and P2. In conclu-sion, the optimum dose of the coffee skin extract for improving sperm quality and microscopic structures of mice testicles is 250 mg/kg BW.

Abstract

The use of bacteria as a biological control agent in aquaculture is such new hope overcoming the negative impacts of the impropriate use of antibiotics. Bacillus is widely known as a potential probiotic for aquaculture, especially which are derived from aquatic biota. Due to a concern that the role of Bacillus as a probiotic agent will be disrupted by residues of antibiotics in the water, this research aimed to identify Bacillus species from common carp intestine based on the molecular method and investigate their resistance to some com-mercial antibiotics that widely used in aquaculture. Chloramphenicol, ampicillin, and metronidazole were used to determine the Bacillus resistance to antibiotics using the Kirby Bauer method. The resistance assay was carried out with a bacterial density of 108 CFU/mL. The results showed that Bacillus isolates derived from common carp  intestine were closely related and resistant to antibiotics. Isolates that resistant to the three types of antibiotics were Cc.1.9 (CgN9) and Cc.2.18 (CgM18).
