Effectiveness test of learning materials using pre-experimental research design one group pretest-posttest involve students of physics education program in STKIP SoE. Data collection techniques were done through validation sheets, observations, test questions, and questionnaire sheets. Validation of learning materials through expert testing shows that learning materials are in a valid category. The results of the study shows that learning materials have a positive effect in improving students' conceptual understanding. The effectiveness of the use of learning materials in improving students' understanding of concepts has been analyzed through the results of N-gain calculations which show a moderate score increase. Moreover, the practicality test of learning materials using a Likert scale shows that learning materials are very practical to utilize as teaching media
The Effect of Noni Leaves’ Age Variation On the Value of Absorbance and Wavelength In Certain Color Spectrums
Get PDFThis research is experimental research. The research aims to analyze the absorbance and wavelength values on the certain color spectrum based on the age of noni leaf sample. Variation in absorption and wavelength occurs in the red spectrum ranges between 650 to 700 nm. Maximum absorption occurs in the middle of noni leaf followed by the tip of noni leaf sample but the yellow leaf sample results poor absorption. Chlorophyll a has main leaf pigment the most which occurs in the light reaction of photosynthesis. The maximum absorption which ranges between 3,5 to 4,0 A occurs in the blue spectrum ranges between 400 to 450 nm. Chlorophyll b absorbs photon energy in sun light. A wavelength ranges between 500 to 600 nm occurs in the green spectrum which has low absorption of three samples ranges 0,5 to 1,5 A. The chlorophyll reflects light of the green spectrum; therefore, it causes low absorption
Web-Based Simulation on Physics Learning to Enhance Digital Literacy Skill of High School Students
Get PDFThe study aimed to investigate the effectiveness of Web-Based Simulation (WBS) on Physics learning to enhance digital literacy skills of Grade XI students in high school. The level of digital literacy skills of the students in the experiment and control group before and after they study using WBS learning and none was determined respectively. The comparison of their levels before and after the study was done to determine the effectiveness of the WBS learning. The participants of this study were 49 students of science class, with 14-16 age. The research design in this study were descriptive-comparison and pretest-posttest experimental design. Data analysis using Anova mixed design with significant 5%. The result of this study are level of students' digital literacy skill before learning process is generally very low; but after the treatment these skill was comparatively increased. In addition, there was a significant difference in the level of digital literacy skill of the classes where the WBS learning is the more effective than direct learning to enhance students’ digital literacy skill
Determination of Fluid Viscosity Coefficient Using jetAudio and Subtitle Edit
Get PDFThe purpose of this study is to produce an experimental design for determining the viscosity coefficient using jetAudio and Subtitle Edit software, and determining the value of the fluid viscosity coefficient by using this experimental design. In this study, the type of fluid used is packaged cooking oil, and the object used is a magnetic ball. The method proposed by the author to measure the travel time of the magnetic ball in cooking oil is by using the combination of coil sensors, jetAudio, and Subtitle Edit.
