Abstract

This study aims to determine the impact of the use of social media, especially YouTube on the mathematics learning outcomes of SMP Negeri 1 Pusomaen students. The social media youtube is the largest video presenter in the world today which contains all types of videos. Most of the students of SMP Negeri 1 Pusomen admitted that they prefer to use YouTube social media when they are at school rather than studying, besides that mathematics subjects are less attractive to students because they are considered very boring, making students rarely study when they are at home. Mathematics learning that is less attractive to students and excessive use of social media during class hours results in student learning outcomes that are still below the KKM. The type of research used is descriptive qualitative. Data collection techniques are observation, questionnaires/questionnaires, and interviews. Data analysis techniques in the form of data reduction, data presentation, and data verification. The results of the study at the time of observation showed that students had various reasons for using YouTube social media, but almost all of the students who were sampled very often used this social media anywhere and anytime, including at school when learning took place. The frequent use of social media by students has an impact on students' mathematics learning outcomes. The distributed questionnaire score data also shows that students really like YouTube social media with a percentage of 56% in the response aspect, and 54% in the reaction aspect. At the time of the research, the researcher tried to find out more about the impact of using YouTube social media on student learning outcomes, by making YouTube social media a learning resource, and it was found that students were very enthusiastic during the learning process and the learning outcomes obtained were 88 out of 100 students. have finished studying. This makes the use of YouTube social media a positive impact if used properly. So, the conclusion that can be drawn from the implementation of this research is that the use of appropriate social media has a positive impact on the mathematics learning outcomes of SMP Negeri 1 Pusomaen students and has a negative impact on student learning outcomes if it is used excessively and not as a learning resource.

Abstract

The goal of this study is to detail the purchasing and selling procedures employed by traders at the Tomohon faith market as well as the arithmetic computation techniques they employ. Research of this kind is qualitative. Interviewing and participant observation techniques were utilized to acquire the data. In this study, the data analysis is qualitative descriptive. Ten traders from the Tomohon faith market were chosen at random to participate as research subjects in this study. The study's findings demonstrate that Tomohon faith market vendors round up their prices when selling their items. The way that traders provide change is to round up the cash that needs to be paid in advance to the nearest tenth, then add it up until the whole sum matches the cash the buyer has paid. The methods used by research participants to calculate addition, subtraction, and multiplication differ significantly from those used in classroom instruction. The value 0, which functions as thousands, is always disregarded. Start by adding the thousands with the thousands, then the hundreds with the hundreds, to determine the total. Some people also finish first to the nearest tens value. If the number being decreased, for example, is 50,000 - 13,000, the reduction procedure is 13 to go to 20 less 7. Then 50 – 20 = 30. The result is 37, which equals 37,000. In addition, you must deduct the first tens of thousands from the second tens of thousands before removing the remaining part of the second figure. Multiply the number from the front number first, for instance, tens of thousands, then thousands, and so on, to calculate the multiplication technique. Find the number that can be divided by the divisor to calculate the division. The outcome of the previous division is then applied to the divided number. This process is continued until all the divided number has been used. The outcomes of these divisions should then be added.
