Science Teacher’s Knowledge about Lesson Study as A Professional Investigation Approach in Learning
No full textLesson study is a teacher collaborative approach to professional development. Lesson study is a model for fostering educator professionalism through collaborative and continuous learning assessments based on collegial and mutual learning principles to build learning communication. The aim of this research is to get an overview of science teachers' knowledge about lesson study as a professional inquiry approach in learning. Surveys of lesson study activities carried out by teachers can help to understand the characteristics of professional learning through effective lesson study and the extent to which teachers carry out and are involved in the lesson study process. The research was conducted in Salatiga, Central Java, Indonesia. This research method uses quantitative descriptive. The data collection technique uses a survey using a questionnaire as an instrument consisting of 70 statements from seven categories regarding lesson study. Respondents were science teachers selected using purposive sampling. Data analysis uses percentage techniques. Based on a survey conducted on science teachers regarding the implementation of lesson study, it is known that there are 5% of respondents who have never heard of lesson study, 30% of respondents have never been involved in lesson study activities, and there are around 40 % of respondents who have never carried out lesson study activities in teaching. Based on the seven categories of lesson study asked to teachers who have carried out lesson study in learning, it is known that there are still teachers who have weak motivation to improve the quality of learning, there are still science teachers who do not understand how to implement lesson study and how to use time in lesson study. Apart from that, it was found that science teachers still had a weak understanding of the benefits of lesson study in increasing teacher collaboration, the benefits of lesson study in improving the quality of teaching and learning, and there were still science teachers who did not understand how lesson study was started
Biochemical Serum Changes in the Liver and Kidney of Hyperuricemia Rats Exposed to Ethanolic Leaf Extract of Hantap (Sterculia coccinea Jack)
No full textHigh uric acid levels can increase oxidative stress in the kidneys causing glomerular damage and tubular ischemia. In addition, it also causes hepatocyte injury so that uncontrolled hyperuricemia will cause liver damage. This study aims to determine the effect of Hantap leaf extract (Sterculia coccinea Jack) on kidney and liver function in rat hyperuricemia. This study was a quasi-experimental study with a post-test only control group design. This study used 30 rats induced with chicken liver juice and potassium oxonate and then given Hantap leaf ethanol extract therapy at doses of 100, 200 and 400 mg/kg BW. Data on urea, creatinine, SGOT and SGPT levels were statistically tested using the ANOVA and Post-hoc Duncan tests. While data on uric acid levels used the T test and Anova. Significantly different results compared to negative controls were found in the group given Hantap leaf extract at doses of 100, 200 and 400 mg/kg BW on uric acid, creatinine, ureum, SGOT and SGPT levels. The results of the study prove that administering Hantap leaf extract can improve kidney and liver function in hyperuricemic rats
Micro-Zonation Mapping of Landslide Potential Using Statistical Weighting Method of Analytical Hierarchy Process (AHP) in South Bengkulu–Lahat Road for Disaster Mitigation
No full textThe research objective was to identify areas with high, medium, and low potential for landslides by micro-zonation on the South Bengkulu–Lahat road, map areas with potential for landslides based on the parameters that contribute to causing landslides using the AHP method, and determine the parameters for landslides, the dominant parameter affecting the occurrence of landslides in the study area. To achieve the research objectives, all parameters that cause landslides obtained at measurement points are then overlaid using the AHP statistical weighting method. The results showed that the area along the South Bengkulu–Lahat road had been identified microzoning high, medium, and low landslide potentials based on statistical weighting from parameters were obtained at the measurement points. For areas with high landslide potential, caution should be exercised, especially during the rainy season with high intensity and long duration

Differences in Appearance of Saltwater, Freshwater and Imitation Pearls with Microscopic Electron Spectrum
No full textThis study aims to identify the differences between saltwater, freshwater, and imitation pearls based on their morphology and topography. Samples were collected from the pearl trading center in Sekarbela, Mataram, Lombok, Nusa Tenggara Barat. The methods employed included physical analysis focusing on origin, formation process, shape, weight, color and light reflection, as well as price. Additionally, morphological and topographical scanning was conducted using Scanning Electron Microscopy (SEM)-EDS to obtain more detailed data. The research findings revealed significant differences among the three types of pearls, particularly in color reflection and luster. Saltwater pearls exhibited the strongest and most radiant color reflection compared to freshwater and imitation. Morphological examination showed pearl grains were irregular in shape and varied in size. Bright colors were predominantly associated with elements having high atomic numbers, whereas dark colors were linked to elements with low atomic numbers. The EDS analysis indicated distinct differences in the chemical composition of each pearl type. Calcium was found to dominate in saltwater pearls, carbon in freshwater pearls, and silicon in imitation. These findings provide deeper insights into the morphological characteristics and chemical compositions of each type of pearl, enhancing the identification of quality differences and the unique traits of each variety
Development of Understanding Test Instruments for Grade 7 Junior High School Students on Temperature, Heat and Expansion Topics
No full textThe aim of this research is to analyze the validity, reliability, level of difficulty and differentiating power of understanding test items, especially on the temperature, heat and expansion topic that has been developed. The test items consist of 20 multiple choice questions which refer to cognitive process of understanding according to Revised Bloom’s Taxonomy. The subjects of this research were 31 students in class VIII of junior high school. Before being tested on students, the understanding test items were evaluated by 5 experts. The method used to analyze validity, reliability, level of difficulty and differentiating power of items is the Rasch model using MINISTEP software version 4.3.1. The results of the analysis show that the understandingtest items on temperature, heat and expansion can be used to test students' understanding. Validity analysis results using item fit criteria with output in the form of MNSQ and ZSTD values. Meanwhile, the value of reliability item of 0.88 indicates that the quality of the items in the understanding instrument is included in the good category. On the other hand, the distribution of the difficulty level of items is uneven, there are more items in the difficult category than items in the easy category. However, 10 items have a differentiating power of more than 0.40 which is included in the very good category, so that they can differentiate students with high and low understanding very well
