The purpose of this study was to find out the mathematical communication skills of students during the scientific approach was applied using graphmatica software on function graph material in college. This research was an experimental study in the category of one group pretest posttest design involving 30 first semester students of mathematics education study program at STKIP Muhammadiyah Pagaralam. The results showed that students’ mathematical communication skills during the applied scientific approach using graphmatica software on function graph material were classified as very good. This means that the use of graphmatica software through the scientific approach can build students’ mathematical communication skills. Through the learning process based on a scientific approach consisting of observing, quetioning, associating, experimenting, and networking, students’ mathematical communication skills both verbally and in writing are classified as very good. For this reason, these activities have a positive influence on students. Beside building students’ mathematical communication this approach also influence students’ learning outcomes. Better the mathematical communication skills, better the learning outcomes. Therefore, building mathematical communication skills is very important in learning especially in learning through a scientific approach using graphmatica software. The use of graphmatica software can be used in other course such as calculus courses. So, graphmatica software can be used in other course so that it is not limited according to the design of the material to be implemented.

Mathematical communication skills are one of the abilities that students must have to make it easier to solve problems contained in mathematics itself and in everyday life. Because if students have mastered mathematical communication skills, it will make it easier for students to take deeper learning. This study aims to analyze the difficulty of students' mathematical communication skills using the Google Classroom Application in the Algebra course. This type of research is descriptive qualitative. The subjects of this study were tree semester students who took Algebra courses in the Mathematics Education study program at Universitas Muhammadiyah Tapanuli Selatan, academic year 2020/2021 as many as 15 people. The instrument used in this study was Test and interview. The results showed that based on the test results obtained: difficulties in the ability to interpret mathematical ideas rationally in writing, difficulties in mathematical problems into mathematical models and difficulties in the ability to express mathematical ideas in the form of descriptions. Meanwhile, based on the results of the interview, namely: (1) technical difficulties, and (2) student adaptation difficulties. To overcome these difficulties, it is necessary which is a combination of Online and Offline learning or also called blended learning.

This research is a field experimental study that aims to find out the difference between the effects of non-ball smash exercises and silent ball smash exercises on the ability of volleyball smash on students of the FOK UNG Sports Coaching Education Study Program. The population and sample involved in this study were 60 students of the FOK UNG Sports Coaching Education Study Program. However, in accordance with the research design, two research groups were formed which consisted of ball-free smash exercises and silent ball smash exercises. The research was carried out for six weeks with frequency of exercise 3 times a week. Based on the results of data analysis using the paired t-test formula and the unpaired ttest at a significant level of 95%, it can be concluded as follows: There is a significant effect of smash training without the ball on the ability to do volleyball smash (to = 8,869> tt = 2,045 ). There is a significant effect of the silent ball smash exercise on the ability to do volleyball smash (to = 13,535> tt = 2,045). There is a significant difference in the effect between the smash ball practice without the ball and the silent ball smash exercise on the ability to do volleyball smash (to = 8,259> tt = 2,000)
