Abstract

Students' understanding of the concepts that underlie evolution are often less than optimal and make it difficult for them to accept the theory of evolution. The aimed of this study were to: 1) map students' knowledge of Mutation and Recombination (M and R); and 2) analyze the effect of gender on their chairperson. This survey research involving 42 Biology Education students at the University of Muhammadiyah Malang was conducted in April 2021. An online questionnaire containing 34 items related to six aspects of M and R was used as an instrument for data announcements. The results, only 30.95% in the category of good knowledge. The aspect of knowledge related to the causes of M and R has the highest average accuracy of answers, while the aspect of the difference between M and R is the lowest.  Only three aspects were significantly correlated with each other. Furthermore, gender has no significant effect on all aspects of student knowledge. The low knowledge of students reported in this study needs to be followed up by improving the quality of Genetics lectures to strengthen students' basic understanding of evolution.

Abstract

Growth medium of bacteria commonly used synthetic medium such as nutrient agar (NA). This synthetic medium was still imported and the price very expensive, therefore, to search an alternative medium needs to be done in order to reduce dependence on imported medium. Alternative medium can be obtained from natural resource that contain nutrient similar as medium in general, such old coconut waste water (Cocos nucifera L). Old coconut water contains glucose, sucrose, protein, minerals, and vitamins. This potential can be used as an alternative growth medium for microorganisms who ferment sugars like Escherichia coli.This study aims to determine the effect of various concentrations of old coconut wastewater (Cocos nucifera L) as an alternative Escherichia coli growth medium. The sample used is old coconut (Cocos nucifera L) wastewater that obtained from Merjosari Market, Malang by setting concentration of 0%, 25%, 50%, 75% and 100%. The result shows old coconut  wastewater medium(Cocos nucifera L) with concentration of 100% has a highest growing number colony of  Escherchia coli, that are 334 x 105. This ability is not much different from used nutrient agar as a omparative medium with total colonies growth are 344 x 105. The concentration of 0% there is no bacterial growth at all. Conclusion from this study is there are growth effects from used various concentrations old coconut wastewater (Cocos nucifera L) as an alternative growth medium of  Escherchia coli and old coconut waterwaste with 100% concentration is the most effective to grow the Eschericia coli.

Abstract

The Covid-19 pandemic has resulted in the face-to-face teaching and learning process being shifted to distance learning which has the potential to affect student literacy levels. This quantitative study aims to determine the effect of gender and grade level on the genetic literacy of high school students in Malang. This survey research used a statement instrument as many as 17 items involving 97 students. Data collection was carried out from November to December 2021. The sampling technique used was cluster random sampling. The research data was tested using a Two-Way ANOVA analysis. The results showed that gender did not have a significant effect on genetic literacy, while class level has significant effect. Furthermore, gender and class level did not have a significant interaction. Further research that examines the effect of other variables on genetic literacy needs to be done.

Abstract

Waste water from the process of making tofu causes environmental pollution because it has acidic and cloudy. The acidic nature of the tofu waste is a result of the process of adding vinegar to the clumping process. Therefore, it is necessary to treat waste before it is discharged into river bodies in order to reduce organic matter and suspended and dissolved solids in the waste water. One of the effective and low cost ways is the phytoremediation process. The water plant that can be used as a remediator is Pistia stratiotes. This study was to determine the interaction between variations weight and remained of Pistia stratiotes on the improvement of the quality tofu waste water and its use as a source of biology learning. The approach and type of this research are quantitative and true experiment. Sampling of waste water was carried out at the industrial center of making tofu as much as 70 liters in Pakunden Village, taking Pistia stratiotes from the swamps around the river flow of Kali Lahar, Blitar City. Sample testing was carried out at Jasa Tirta I, Malang. This study consisted of 10 treatment groups and 3 control groups with 3 repetitions with variations weight of 80 g, 90 g, 100 g, 110g, 120g and remained of 7 days and 14 days. The experimental design used in this experiment was a completely randomized design, the results of this study can be used as a source of information on Biology learning that has been adjusted to the 6 requirements of learning resources.

Abstract

The problem of koi fish farming in Blitar Regency that is causing concern and has not been resolved is a disease caused by ectoparasites. The purpose of this study was to observe the types of ectoparasites and the prevalence of parasites that attack koi fish in cultivation centers in Blitar Regency. This type of research is descriptive research with a survey method approach. The koi fish sampled were koi fish fingerlings measuring 7-15 cm in the Kohaku, Tancho, Ogon, and Utsuri varieties with three individuals each. Sampling using purposive sampling technique. Examination of ectoparasites was carried out by cutting the body parts of the fish (fins, gill lamellae, and tail), then placing them on a glass slide, dripping with distilled water, covering with a cover glass, and observing under a microscope. The results of the ectoparasites examination were analyzed descriptively quantitatively. The data obtained is tabulated in tables and graphs and paired with related literacy. The results showed that there were 5 types of ectoparasites, namely: Lerneaea sp., Argulus sp., Trichodina sp., Dactylogyrus sp., and Gyrodactylus sp., with different numbers and prevalence in each variety. The highest prevalence of ectoparasites in 4 varieties of koi fish was in the Ogon variety (66.6%) with the very frequent infection category, and the lowest in the Kohaku, Tancho, and Utsuri varieties (33%) with the general infection category. The highest prevalence of each type of ectoparasites was Gyrodactylus sp., amounting to 66.6% (very frequent infections) with 3 individual parasites, and Dactylogyrus sp., amounting to 33% -66.6% (general infections - very frequent) with 7 individuals.

Abstract

The outbreak of the COVID-19 pandemic in the world has urged researchers to develop a vaccine or therapeutic drugs to fight this virus. This study aimed to assay 14 deoxy-11,12-didehydroandrographolide (AGP 2) ability as an inhibitor of 3-chymotrypsin like-protease (3CLPro), Papain-like protease (PLPro), and RNA-dependent RNA-polymerase (RdRp), the viral proteins of SARS-CoV-2 and to evaluate it safeness as a drug candidate. In-silico technique was performed in this study to analyze the binding interaction, complex stability between protein and ligand, and drug-likeness properties. The proteins and ligands were obtained from Protein Data Bank (PDB) and PubChem web tools, then using PyRx to identify the binding affinity score, PyMoL to visualize the 3D binding interaction, and WebGro web tools to analyze the stability of each complex. A drug-likeness evaluation was done using SwissADME, pkCSM, and Way2drug web tools. The result of this study showed that the binding affinity score for each complex is; AGP 2-3CLPro (-6.7 kcal/mol), AGP 2- PLPro (-6.4 kcal/mol), and AGP 2-RdRp (-7.0 kcal/mol) where the AGP 2-RdRp and AGP 2-3CLPro showed a stable form indicating the inhibitor ability of AGP 2. This study also demonstrates that the drug-likeness properties of AGP 2 are safe to use. Additionally, it has been proved that AGP 2 can be developed into a therapeutic drug with further studies.
