Abstract

Background: Habitat is a place for living things to grow and develop. Differences in habitat in an area can affect the size of an organism. This study aims to determine the morphometric variations of Tetragonula laeviceps found in urban and forest habitats in Central Sulawesi Province. Methods: This research was conducted with roaming technique. Morphometric characters observed were 35 characters of stingless bee and analyzed using Microsoft Excel software. Results: The results of this study indicated that the morphometric size variation of T. laeviceps found in forest habitats (3.58 mm) is greater than that of wild bee in urban habitats (3.05 mm). Conclusions: Different habitat characteristics can affect the morphometry variations of the bee, especially in T. laeviceps species. The bee's morphometry body size is greater than in the forest habitat, because in that habitat there are environmental temperatures and types of plant sources of nectar which are more supportive for bee life compared to urban habitats.

Abstract

Background: Anoa is an endemic animal on Sulawesi island which is threatened with extinction, both lowland anoa (Bubalus depressicornis) and mountain anoa (Bubalus quarlesi) which share the status of Endangered. The aim of this study is to determine the condition of lowland anoa and mountain anoa on the Sulawesi island in terms of the type of feed. Methods: This research was accomplished using literature review techniques. Results: The outcome of this study showed a represent that lowland anoa in terms of feed type has an endangered status, as well as mountain anoa in terms of feed type, which is endangered. The status of the existence of lowland anoa and mountain anoa, both from the type of feed and the IUCN conservation organization, is equally threatened with extinction. The same condition and conservation status is obtained by the result because the two different anoas that lives in different habitats are able to adjust their own feed according to where the animals are. Conclusions: Although it has no bearing on anoa condition and conservation status, it is expected that the national park and captivity of anoa on Sulawesi Island can better sort food for lowland anoa and mountain anoa to support their physiological functions for their existence.

Abstract

Background: SARS-CoV-2 is a new type of coronavirus of the genus Betacoronavirus and the family Coronaviridae that causes a respiratory disease called COVID-19. The virus has a sheath and genetic material in the form of single-chain RNA. The genome structure of this virus is divided into two types, namely genes that encode non-structural proteins consisting of the ORF1a / ORF1b gene and genes that encode structural proteins consisting of spike glycoprotein (S), envelope (E), membrane glycoprotein (M), and nucleocapsid protein (N). Methods: The method of detecting SARS-CoV-2 with real time RT-PCR is the most recommended method because it has high specificity and accuracy. The specificity of a method is necessary to be able to specifically recognize the pathogen that causes the disease. Real time RT-PCR requires sampling with a swab on the oropharynx or nasopharynx to be examined in the laboratory which later the presence of viral RNA becomes a molecule that is assessed for diagnosis results. In this study, volume optimization was carried out on the Da An Gene kit used for the detection of SARS-CoV-2 with Reverse Transcription Polymerase Chain Reaction (Real time RT-PCR) with the aim of saving the use of reagents from available kits but with amplification results remaining optimal and accurate. Results: There were three SARS-CoV-2 RNA samples used consisting of N62, N63, and N79 samples and three types of total volume used were 20 μl, 15 μl, and 10 μl. The results of this study showed that the three positive samples contained SARS-CoV-2 with a Cq value of < 40. Conclusion: A volume of 20 μl is the optimal volume, which is more efficient than the manufacturer's recommended volume of 25 ul.

Abstract

Background: Numerous types of research on malaria were done over a long period of time but there are still some unknowns. However, it is globally known that malaria is caused by the Plasmodium parasite, mainly and most lethally by Plasmodium falciparum. The purpose of this research is to understand the structure and function of three uncharacterized P. falciparum proteins (PF3D7_1468000, PF3D7_1147400, PF3D7_1351100) using bioinformatic methods in hopes to learn more about malaria. Methods: The three uncharacterized P. falciparum proteins were inserted into Phyre2 for knowing the protein homology, InterPro, and SUPERFAMILY hidden Markov models for understanding the domain annotation, scanprosite for knowing the post-translational modification, Ramachandran plot for protein validation, and Yasara for visualizing the protein. Results: According to the Phyre2 results, the third protein showed the highest confidence and coverage level of 100%, followed by the second protein, and the lowest was the first protein. Interpro and SUPERFAMILY results identified the first protein as WD40 repeat superfamily, the second protein as Cytochrome C subunit II-like, and the third protein as CXXC motif. Scanprosite revealed all sequences possessing protein domains in which the first protein has three protein domains, the second protein has one protein domain, and the third protein has two protein domains. According to the Ramachandran plot, the first and second protein generally has an α-helix structure while the third protein has an overall β-sheet structure, which differs to some extent from the protein structure visualization. The three protein visualizations exhibited secondary structures and more than 50 amino acid residues for each protein. Conclusion: This research concluded that the second and third uncharacterized proteins (PF3D7_1147400, PF3D7_1351100) could be promising antimalarial drug targets leading to the P. falciparum parasite death.

Abstract

Background: Representation is a tool to improve students' communication, interpreting, and problem-solving skills. Visual representation (RV) can provide information about understanding the object/phenomenon observed about the concept under study. This study aimed to determine the relationship between visual representations and material content and the relationship between visual representations and the reality of images contained in the Circulation System material. Methods: This study used a content analysis method with a qualitative data analysis technique. Results: The analysis results show a relationship compared to the category of significant relationships on the circulation system's material and the relationship of symbolic visual representations. Conclusions: The analysis that has been carried out on the visual representation of SMA/MA biology books in the city of Stabat for the circulation system material, it can be concluded that the Visual Representation relationship contained in SMA/MA biology books was found to be more dominant for the category of no relationship compared to the category of a significant relationship in circulation system material presented. In addition, when analyzed concerning the reality of the image, the visual representation displays the relationship of symbolic visual representations in the analyzed biology textbooks. In addition to choosing a textbook, the teacher should pay attention not only to the content of the learning material but also to look at the components in the book, one of which is the picture in the textbook. This will later be useful to support students' understanding of the concepts being taught.
