Abstract

Science process skills are skills that need to be developed in students in learning science such as science. The low level of KPS on the science concept is influenced by the learning model which emphasizes the aspects of receiving full information from the teacher. Student KPS is also dominated by an increase in scientific attitudes that require students to show their sensitivity to the surrounding environment. This study aims to determine science process skills and increase students' scientific attitudes through the implementation of the contextual teaching and learning model at MTsS Muta'allimin Aceh Besar. The method used in this study was an experiment with a one-group pretest-posttest design. The instruments used were observation sheets and questionnaires. The results showed that the implementation of the CTL learning model could improve students' KPS in both categories with an average score of 71-85 and very good categories with an average score of 86. In addition to improving the KPS learning model implementation, CTL can also improve students' scientific attitudes with a value N-gain average of 0.63 including the moderate category. The results of the improvement obtained by the average student are in good categories with an average score of 71-85 then the category is very good with an average score.  86-100. The conclusion in this study proves that the CTL model can improve student learning skills and scientific attitudes, especially the material of vibration, waves, and sound

Abstract

This study aims to test the effectiveness of the blended learning rotation model to improve the scientific literacy skill of prospective teacher students. The design of this study used the Posttest-only design with nonequivalent groups. The research subjects were 76 students majoring in biology education at Universitas Mataram. The research was done to two experimental groups, namely the blended learning station rotation model (BLSRM) and regular learning (RL). The research instrument used a multiple-choice test which refers to the aspects of scientific literacy competence according to PISA. The data analysis technique was carried out descriptively, complete with the Hotelling's T2 test to test the effect of BLSRM on students' scientific literacy skills. The results showed that students' scientific literacy skills were in the very low category (mean BLSRM = 38.50, RL = 34.22) and there was no effect of BLSRM on students' scientific literacy skills (Hotteling Trace = .098 and Sig. = .080). To improve students' scientific literacy skills, BLSRM needs to be combined with other models such as problem-solving model, so it can be an effective strategy in science learning

Abstract

The problem in the harmonic vibration practicum is in calculating time accurately. Commonly, the time counter used was a stopwatch, but it was unable to provide valid data. As a result, the student has difficulty seeing the relationship between concepts with practical results in the laboratory. To overcome these problems, in this study, we developed a harmonic vibration practicum tool that is equipped with a digital timer using an Arduino Uno microcontroller as a light sensor. An Arduino can be programmed via a PC according to the wishes of the developer. This study was development research using a 4-D model (Define-design-develop-dissemination). The define and design stages respectively to find problems in the harmonic vibration practicum tool. The tool is finally designed and then calibrated, validated, and practical. The calibration results show that the percentage difference for repetition measurement and comparison that values with theory was 0.008% and 3.98%, respectively. In addition, the validation results show an average percentage of 87% or very valid. For practicality, the result through a limited test of Physics students of IAIN Batusangkar in the second semester shows a very practical response with a percentage of 85.96%. Due to time constraints, the dissemination stages have not been carried out in this study.

Abstract

Potassium is a nutrient that plays a role in maintaining the function of the muscles and nerves that control the heart and is needed for body stability. The potassium content in the body can be obtained from foods such as bananas. The development of instruments and methods that are developed to obtain a more accurate measurement of potassium concentration requires an instrument that has high linearity and sensitivity. The instrument is in the form of an optical sensor system equipped with the use of optical fibers to guide the waveform to maintain its intensity stability. In this study, an experimental method was conducted with a sample of a standard solution with potassium as the solute and pure water as the solvent. Then continue to measurements on samples of banana milk and green banana fruit extracts. The results of the analysis of the measurement data using an optical sensor with a concave mirror reflection plane obtained a sensitivity of 0.36 mV/ppm and a linearity of 82.56%. In the plane of the flat mirror reflection, obtained an optical sensor with a plane mirror reflection plane shows a sensitivity of 0.12 mV/ppm and a linearity of 97.6%. The highest and most accurate linearity value is found in the plane mirror plane results. The next stage is the result of the maximum output voltage read on the optical detector through an optical sensor with a sample of extracts of milk banana and green banana. The results of data analysis on the linear equation with the highest linearity obtained the potassium content in milk bananas of 391.54 ppm and the green banana extract solution obtained 307.91 ppm, so it can be concluded that the potassium content in milk bananas is higher than green bananas with a linearity of more than 97%.
