Abstract

Rearing insects such as dragonflies and damselflies aim to gain uniform progeny that used for scientific purposes. In Indonesia, unfortunately, this rearing type is not yet common which suggests the time for its initiation. This study has objective to define the type of rearing cage for Agriocnemis femina damselfly (Odonata, Zygoptera, Coenagrionidae). It was conducted descriptively by using two smalls (9 x 13 x 23 cm), four medium (14 x 15 x 22 cm) and two larges (20 x 23 x 33 cm) size boxes as cage setups, with or without ornamental plants in it. The feeding was with limited (10-15 Drosophila flies provided per day) and unlimited provision. Data was analyzed descriptively. The results showed that A. femina lived normally, including eating and mating, within the large cage setup equipped with ornamental plants and unlimited feeding.

Abstract

The fern is one of the highly diverse vascular plant species, which has a unique characteristic. The closely related at the family level because the genera within each family have some uniformity so that the relationship and groupings cannot be distinguished. One example of a diverse fern family is Polypodiaceae. Consequently, it is necessary to simplify the classification; one of them is through phenetic relationship analysis. This study aimed to analyze the phenetic relationship of the Polypodiaceae ferns in Climbing Cemoro, Mouth Lawu enclosure, Karangayar Regency, based on the similarity index on the dendogram. The data were collected using the exploration method and the sporophyte morphological characters were observed. The observations obtained 13 variations of characters. The relationship analysis was carried out with the hierarchical cluster program using SPSS 23. There were six species found from the Polypodiaceae family, there were including Belvisia mucronata, Goniophlebium sp, Lepisorus sp, Pyrrosia piloselloides, Crypsinus taeniatus and Drynaria sparsisora. The finding suggests that six species are divided into two clusters, the Group I consisting of Goniophlebium sp, Lepisorus sp, Lepisorus sp, and Pyrrosia pilloselloides with a similarity coefficient index of 53% and Group II consisting of Drynaria sparsisora, Goniophlebium sp, and Pyrrosia piloselloides with a similarity index of 46%.

Abstract

Single-cell protein (SCP) is the term used for crude or pure protein derived from simple single or multi-celled microorganisms. Pineapple peel contains monosaccharides as much as 10.8% so that it can be used as a fermentation medium in single-cell protein production. The purpose of this study was to determine the effect of adding carbon sources of fructose and sucrose on pH, cell dry weight, and protein content in the manufacture of single-cell proteins. This study used a completely randomized design (CRD) with two factors, namely the addition of carbon (fructose, sucrose, and control) and fermentation time (24.48, and 72 hours). The data analysis used the variance test and the Duncan Multiple Range Test (DMRT) continued to test with a confidence level of 95%. The results showed that the addition of carbon to the media had a very significant effect on media pH, cell dry weight, and protein content. In the medium with the addition of fructose it has a pH of 3.81; dry weight 0.4203 grams; and protein content 69.08/L. Whereas in the media with the addition of sucrose, the pH was 4.33, the dry weight of the cells was 0.3385 grams, and the cells had a protein content of 85.55 mg/L. The addition of a fructose carbon source gave the cell dry weight more than the addition of carbon sucrose

Abstract

The coral reef ecosystem is one of the typical tropical ecosystems with high biodiversity which has an important role both biologically, ecologically, physically as well as socially and economically. Several coral reef areas in Indonesia were reported to have suffered damage, not only due to climate change which has an impact on rising sea surface temperatures and ocean acidification but also due to anthropogenic factors and irresponsible management of marine tourism. This study aimed to analyze the condition of coral reefs based on covering in Pramuka Island, which is one of the famous tourist destinations in the Seribu Islands. The study was conducted using Line Intercept Transect (LIT) method at predetermined coordinate points. The results showed that the dominant coral reef life form was Acropora Submassive (ACS), namely 18.9%, and Acropora Branching (ACB) as much as 12.48%. Besides, the types of life forms found were coral foliase (9.42%), Miliepora Coral (9.2%), Coral Massive (4.8%), Acropora Encrustring (4.24%), and so on. Based on the results of this study, it can be concluded that the condition of coral reefs in Pramuka Island is still relatively good with a total coral cover percentage of 72.38%. Efforts to protect the coral reef ecosystem in this area need to be considered so that its condition can be maintained.

Abstract

Exotic plants are plants that are introduced intentionally or unintentionally from their original habitat to a new habitat. One of the exotic plants that is potentially invasive is Chromolaena odorata. These plants are found a lot especially in the rehabilitation zone at Donglo Block Resort of Wonoasri, Meru Betiri National Park (MBNP). An initial effort to determine whether this exotic plant was potentially invasive was to use the distribution pattern of a plant population. This study aimed to determine the distribution pattern and area of cover of exotic plants C. odorata in rehabilitation zone at Donglo Block, Resort of Wonoasri MBNP. The sampling of C. odorata used the transect plot method systematically, which carried out in Donglo Block Resort of Wonoasri MBNP. Data analyzed using Morisita index. The map of distribution pattern of C. odorata was created using the Geographic Information System (GIS). Based on the results of the Morisita index, the value (Iδ) = 12.39, which means that C. odorata has a clumped distribution pattern. The distribution pattern of C. odorata can also be seen from the visualization of the spatial distribution map, which shows that the growth of C. odorata in plants or overlaps with each other, hence that it looks clustered. The coverage area of C. odorata in the study location was 596,5 m2 or 29.24% of the total area of the study (20,400 m2). Based on the results of the coverage area of C. odorata, it was indicated that this exotic species is not yet classified as an invasive species in the area.

Abstract

Microplastics are harmful to the ecosystem and need to solve immediately. Detection of microplastic contamination is the first step to reduce plastics pollution. Estuarine in Puger has a high potential for microplastic pollution related to the multifunction of waters as ports, tourism, fish market, fish processing, and human settlements. However, there are no studies related to microplastic contamination in the area. The objectives of this research were to determine microplastic contamination in the estuarine located in Puger District, Jember Regency, Indonesia. The research results were the first evidence to inform the society and local government about the actual condition of plastic pollution, especially in the aquatic ecosystem. The sampling sites were determined by purposive sampling. Fifty liters of water from each station (with three repetitions) were taken using a 24V water pump and then filtered using stainless steel filter (mesh 5 mm and 0.2 mm). The filtered samples were placed in a sterile bottle sample, stored at 4 ± 20C. Microplastics were counted and categorized according to size, color, and type under a microscope stereo. Microplastic abundance was calculated based on the number of microplastic particles identified per liter of sample water (particle/liter). The result showed that the study area was contaminated by microplastics throughout site sampling, with abundances varying from 0.03 particles/liter to 0.19 particles/liter. The highest microplastic abundance found near the fishery market. The microplastics also vary in size, color, and type. According to characterization, the sources of microplastic contamination come from human-based activities.

Abstract

Bali cattle are superior meat producers, but they are susceptible to Jembrana disease. The injection of the crude vaccine was considered ineffective, so the env-su gene was selected to express the Jembrana Surface Unit (JSU) protein as a candidate for the Jembrana vaccine. This study aimed to analyze the potential of the JSU protein as a candidate for the Jembrana vaccine and analyze the increase in the env-su gene expression which codon has been optimized in silico. Vaccine design was carried out through in silico including the selection of the SU protein sequences of the genus Lentivirus and sequence alignment of UniProt. The construction phylogeny tree of SU protein using MEGA-X program, optimization of env-su gene codon with preference codon Esherichia coli str. K-12 substr. MG1655 using Optimizer. The optimized env-su gene was inserted into the plasmid pET-21a (+) using GenScript. The result of sequence alignment showed that there is no SU protein that has a percent identity value of more than 30% with JSU protein. The SU JDV and BIV proteins are monophyletic groups and have a percent identity of 20.57%. Codon optimization showed an increase in CAI by 1,000 and GC 54.5%, and a decrease in ENc to 22 and AT 45.5%. EcoR1 and HindIII can recognize the gene target and MCS cut regions on the plasmid so that the env-su gene can be inserted into the pET-21a (+) plasmid. The JSU protein has the potential to be a candidate for the Jembrana vaccine, but it needs further research in vitro and in vivo.

Abstract

Selorejo Waterfall is a natural tourism area that is quite far from downtown Ponorogo and directly adjacent to the Gunung Sigogor Nature Reserve. Hence, this area has the potential as a natural habitat for dragonfly and damselfly. The presence of dragonfly and damselfly species is determined by the type of habitat, canopy conditions, vegetation diversity, and the microclimate that exists in a location. This study aimed to determine the diversity of dragonfly and damselfly and to determine the community structure of dragonflies in Selorejo Waterfall. The sampling method was Visual Day Flying. The results of research conducted in two streams showed that there were 12 species from 6 families with a total of 230 individuals. The value of species diversity at this location is H '= 2.05. In the community structure at the Selorejo Waterfall dragonfly, there are differences in the number of species and individuals in the two streams in Selorejo Waterfall Area. The large stream, eight species from four families, 151 individuals in total. Meanwhile, in small stream, there were nine species from six families, 79 individuals in total. The differences in the number of species and individual dragonflies in the two streams at Selorejo Waterfall can be used to describe the diversity and structure of the Odonata community in the area.

Abstract

SARS-CoV-2 is a virus that has caused COVID-19 pandemic. This virus is a new variant of the SARS-CoV virus and also closely related to MERS-CoV, which caused similar acute respiratory infections. All these viruses recognize target cells by binding to the Receptor Binding Domain (RBD) on Spike protein with receptors. This study aimed to determine the SARS-CoV-2, MERS-CoV, and SARS-CoV genome structure, Spike protein sequence differences, and variations of RBDs Receptor Binding Motif (RBM). This research was using data mining approach. Genome sequences were downloaded from NCBI, except for Indonesian samples were downloaded from GISAID. Genomic structures, Spike sequence, and RBD structure were analyzed using Bioedit, followed by protein modelling using SwissModel and PyMol applications. The result showed that the SARS-CoV-2, MERS-CoV, and SARS-CoV genome shared the same genes yet in different numbers and length. SARS-CoV-2 Spike protein sequence was quite similar to SARS-CoV Spike protein, but very different to the Spike protein of MERS-CoV. There were variations of RBDs RBM structure due to the mutations occurred among these viruses. It is suggested that these differences may increase the affinity between SARS-CoV-2 Spike protein to its hACE2 receptor which caused SARS-CoV-2 becomes more infective and spread wider than SARS-CoV and MERS-CoV, in turn. This result expected to be basic information for the development of SARS-CoV-2 introduction inhibition agent and spreading prevention.
