Abstract

Abstract and complex learning materials presented with monotonous models can lead to decreased motivation and suboptimal learning outcomes due to student boredom. This study aims to determine the effect of the make-a-match assisted scramble learning model on grade X students' learning motivation and learning outcomes on atomic structure material. The research method was quasi-experimental with a nonequivalent pretest-posttest control group design. The research location at A Sleman High School for the 2023/2024 academic year uses two research samples: class XC as an experimental class and class XG as a control class. The sampling technique used is cluster random sampling. Data were collected using learning motivation questionnaires and test questions. The Mann-Whitney test was applied to analyze the data, revealing significance values of 0.045 and 0.000, both below the 0.05 threshold. The results indicate that the make-a-match assisted scramble learning model significantly enhances learning motivation and outcomes for class X students on atomic structure material.

Abstract

Oryzias hubbsi's distribution is rarely discussed, as it is believed to only occupy the western part of Java, while its conservation status is Near Threatened (NT) as of 15 October 2018 on the IUCN red list. Specimens of O. hubbsi were recorded from Bandung and Jakarta in the description, other reports for O. hubbsi are commonly from Southern Sumatra-Western Java (SWJ) ecoregion in Java. However, an unexpected discovery of the genus Oryzias in Semarang freshwater opens up opportunities for the hidden spread of O. hubbsi to Central Java, and especially to other ecoregions which is Central and East Java (CEJ). Morphological approaches with distinctive O. hubbsi characters, complemented by molecular approaches with O. hubbsi samples from the Bogor population, confirmed similarities of species between both populations. Genetic distance using p-distances between both populations was below 2%, both populations made obvious clusters with a gap of 0.5%, and differed by five nucleotide base sites only. This new distribution record of O. hubbsi can be a foundation for conservation and domestication planning efforts.

Abstract

The purpose of this study is to ascertain how the problem-based learning approach affects students' critical thinking abilities in courses on conservation biology. This study design uses a non-equivalent control group in a quasi-experiment. Essay exam questions totaling 10 valid and reliable numbers served as the study's instrument. Pre-test and post-test questions were used to gather data. Descriptive statistics and inferential statistical tests, namely the covariance (ANCOVA) analysis with pretest values as variables at a significance level of 0.05%, were used to evaluate the research data. The IMB 23 SPSS program was utilized for data analysis because the data were homogeneous and regularly distributed. The findings demonstrated that, with a significance value of 0.000 < 0.05, there was a significant difference in the critical thinking abilities of students taught using the conventional model and those taught using the problem-based learning model. The conclusion is that in conservation biology classes, the problem-based learning approach helps students develop their critical thinking skills.

Abstract

Bromelain enzyme is one type of protease enzyme that has the ability to hydrolyze protein peptide bonds into amino acids. Bromelain enzyme can be found in pineapple (Ananas comosus) which consists of 95% cysteine protease mixture. Bromelain is often used by athletes to treat physical injuries or minor wounds. In obtaining the bromelain enzyme found in pineapple, an isolation process is required, namely by extracting it extracellularly. The method in this study does not go through the cell breakdown process so that it is easier to separate from other impurities and does not mix with other cell materials. This study aims to develop an innovative method in the production of bromelain enzyme using pineapple and honey as raw materials and to evaluate the organoleptic properties, pH, and the presence of lactic acid bacteria. This study is a descriptive study presented in the form of graphs and images. From the research that has been done, it can be concluded that the manufacture of bromelain enzyme using pineapple and honey has succeeded in producing a product that has an organoleptic value of liking (60%), pH 3 (acid) with the number of lactic acid bacteria 2.43 cells/ml.

Abstract

Diabetes mellitus has raised concerns about structural and functional changes in blood cells, as well as changes in blood impedance. The purpose of this study is to investigate the relationship between electrical impedance values measured with the Bioelectrical Impedance Analyzer (BIA) in diabetes patients. Blood samples were collected from 5 healthy people and 5 diabetes patients for the study. Electrical impedance testing with a BIA. The impedance method determines the electrical properties of blood by measuring its resistance and reactance at various frequencies. The results of the BIA are analyzed and compared to body health parameters such as the blood glucose level index. The average electrical impedance value in diabetes mellitus patients measured at a frequency of 100 Hz to 100 kHz with a current injection of 10 μA was found to be lower than the average electrical impedance value in healthy people. This study shows that the electrical impedance value of diabetes mellitus patients is lower than the impedance value of healthy people. This is consistent with diabetes mellitus patients' blood glucose levels, which are higher than healthy people's blood glucose levels.
