Abstract

This research is based on the problems in SMAN 10 Padang, namely the low attention of students during the learning process takes place. One of the factors that influenced it was the use of cellphones during the learning process. Students tend to use mobile phones not only to find learning material, but also use it for personal purposes such as replying to messages or playing games. Submission of material by teachers tends to be less interesting and monotonous, to overcome students' lack of attention in learning using PowerPoint. The purpose of this study was to see the effect of using Powerpoint in increasing the learning attention of class X students at SMAN 10 Padang. This type of research is a quasi-experimental design with Randomized Control-Group Posttest Only Design. The population in this study were all tenth grade students of SMAN 10 Padang. The sample in this study were class X students of SMA N 10 Padang Academic Year 2018/2019 and the samples used were students of class X MIA 2 as a control class and X MIA 3 as an experimental class. The instrument used to assess students' attention is the student learning attention assessment sheet filled in by the observer. Based on the results of the study using the t-test it can be concluded that there is an influence of the use of PowerPoint in increasing student learning attention. It was proven that the average attention of the experimental class was higher than the control class.

Abstract

 Learning media is one of the determinants of success in the learning process in school. The use of learning media will greatly help the effectiveness of the learning process and add one of the teaching materials that can be used by students in learning. But the role of learning media will not be seen if its use is not in accordance with the learning objectives that have been formulated. Students find it difficult to connect the concepts contained in the material, then students find it difficult to understand the material concepts. The material on biology teaching materials used is like narration, language that is difficult to understand, and the appearance is less attractive. To overcome this problem, the teacher needs to develop teaching materials that are expected to be interesting and easy to understand by students in understanding the concepts contained in biology learning material. Teaching materials developed are Handouts. This research is Development Research conducted at FMIPA UNP and Padang Junior High School 23, using the Plomp development model (2013). The subject of this study consisted of 2 lecturers of Biology Department FMIPA UNP, 1 Biology teacher at SMP 23 Padang, and 29 students in grade VII of SMP 23 Padang. The data in this study are data obtained from the validity test questionnaire and practicality test.
