Abstract

Purpose of the study: To find out the application of the Concept Attainment model with the help of fractional card media in increasing understanding of the concept of fractions in class II Ahmad Dahlan Elementary School. Methodology: The research was conducted at Ahmad Dahlan Elementary School in the even semester of 2018/2019. The research sample was 22 students. Research data obtained through student learning outcomes and observation sheets. Quantitative data were analyzed using descriptive statistics and Qualitative data were analyzed to determine the learning process using the Concept Attainment learning model based on fractional card media. Main Findings: The results of the study show that the application of the Concept Attainment model assisted by fractional card media can improve understanding of the concept of fractions. By observing the results of understanding the concept of fractions in the first cycle, namely 53.01%, it increased in cycle II to 77.12%. In cycle I the results of the written test evaluation with classical completeness of 63.15% increased in cycle II by 18.66% to 81.81%. Novelty/Originality of this study: The latest research in this research is to combine the concept learning learning model with fraction card media which is generally not widely used, especially for learning fractions in elementary school mathematics, the benefits for students in this action research will then make it easier for them to face more difficult learning levels in the next class and can become a new teaching idea for teachers to facilitate student understanding.

Abstract

This study aims to determine the effect of silica sand mass in the air purification system on the decrease in Fe concentration. The type of research used is experimental research. The water purification media used in the research were silica sand and gravel. The mass of gravel used in the water purification system is constant, namely 500 grams. The mass of silica sand used varies, namely 200 grams, 400 grams, 600 grams, 800 grams and 1000 grams. The research was carried out through three stages, namely the stages of preparation, implementation, and data collection. The effect of the mass of silica sand in the air purification system on decreasing the concentration of Fe showed positive results. The results of research with a fixed mass of gravel and varying masses of silica sand showed a decrease in Fe concentration after water purification with a value that met environmental health quality standards and water health requirements Fe (iron) content below 1 mg/L or ppm so that the water worth using.
