Abstract

Background: Indonesia has abundant biodiversity. The concept of biodiversity was chosen because there are still places that must be known that students can use as learning resources. The learning innovation carried out is the application of environment-based knowledge to improve students' understanding of the concept of biodiversity. Method: This study used a pretest-posttest group design, 105 students of class X SMA Negeri Asera. The research sample consisted of 2 classes, namely the experimental and control classes. The experimental class uses environment-based learning and the control class uses conventional learning. The data was obtained through a test of understanding the concept of biodiversity and interviews. Data analysis was carried out by descriptive analysis and inferential statistics. Hypothesis testing through t-test using SPSS 20.0 program. Result: There is a difference in values between the experimental and control classes, where the experimental class values are higher than the control class values with that = 10,899. Conclusion: The application of this environment-based learning can affect student learning outcomes of SMA Negeri Asera.

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

Skin cancer is a disease that can cause the loss of the ability to regenerate and protect the skin normally. The types of skin cancer that are known are melanoma and non-melanoma skin cancer. Non-melanoma Basal cell carcinoma is a malignant neoplasm originating from non-keratinizing cells in the basal layer of the skin's epidermis. The treatment itself is carried out through the application of immunotherapy, namely the use of drug therapy Programmed Death Ligand 1 (PD-L1). This study aims to see the effectiveness of PD-L1 Therapy as a treatment for basal cell carcinoma. The focus of the study of the article is the integument system, skin cancer, non-melanoma basal cell carcinoma, and the effect of anti-PD-L1 use. The research method used is a literature review from various sources. Skin cancer Basal cell carcinoma attacks the basal cells of the epidermis, causing disruption. Attacks slowly, but when ignored will spread wider and more severe. Through PD-L1 therapy by binding to PD-1 receptors on immune cells, it causes the activation of T lymphocytes as anti-cancer cells in the body that suppress growth while actively controlling tumor cells. Through the use of PD-L1 therapy in treating cancer that attacks basal cells, it will suppress growth, destroy and shrink cancer cells, and increase the body's immunity against cancer cells.

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

Backgrounds: Heavy metal that pollutes the river area affects living organisms which reside in it. Contamination of heavy metal in Ciliwung River leads to the presence of heavy metal elements (Cd, Hg, and Pb) inside the body of the plecos (Pterygoplichtys Pardalis) which inhabits that area. Hence, the utilization of plecos flesh and bones as a raw material in processed food products (e.g. shredded fish, shumai, and fish flour) might be harmful for human. Accumulated load of heavy metal in human's body would likely trigger health problems. Insufficient data on heavy metal concentration in Ciliwung River plecos-based food products underlies this research, with the aim to calculate the concentration of heavy metal Cd, Hg, and Pb on the previously mentioned plecos-based shredded fish, shumai, and flour. Methods: Heavy metal Cd, Hg, and Pb concentration analysis using X-Ray Fluoresence (XRF) methods conducted on PAIR Batan. Results: Value of Cd on shredded fish <0.5 mg/kg, shumai 0,7 mg/kg, head+tailbone and body skeleton flour <0.3 mg/kg. Value of Hg on shredded fish and shumai <0.7 mg/kg, head+tailbone flour 0.3 mg/kg, body skeleton flour 0.4 mg/kg. Value of Pb on shredded fish 1.3 mg/kg, shumai 0.8 mg/kg, head+tailbone flour 2.3 mg/kg, body skeleton flour 1.6 mg/kg. Conclusions: Heavy metal concentration on Ciliwung River plecos-based processed food products (shredded fish, shumai, and flour) has exceed maximum limit of Cd, Hg, and Pb determined by SNI, BPOM, and FAO.

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.
