Relationship Between Social Media and Student’s Communication Ethics at SMPN 2 Palangka Raya

2022-06-08T14:53:02+00:00

Abstract

This study was conducted to determine the relationship between the intensity of the use of social media with students' communication ethics. This research is a correlation study, with a sample of 48 people. The main data collection technique in this study used a questionnaire on the use of social media and communication ethics to determine whether there was a relationship between the use of social media and students' communication ethics. From the results of research analysis using product moment correlation obtained r count of -0.018. Looking at the 5% significance level in the product moment r table with dk = n-2 = 48-2=46, it is obtained a value of 0.291 at a significance level of 5%. Thus, the value of r arithmetic < r table with a level of sig (2-tailed) is 0.905 more than 0.05. And it can be interpreted with the degree of relationship that the relationship between the intensity of social media use and communication ethics is low, which lies in the coefficient interval of 0.00 – 0.199. With the conclusion that there is a relationship between the intensity of the use of social media on communication ethics. Indeed, in the results there is a relationship, but the relationship is negative and less significant. Where the higher the intensity of using social media, the lower the communication ethics of SMP N 2 Palangka Raya students.

ANALYSIS OF THE DIFFICULTIES OF CLASS X STUDENTS OF SMKN 4 PALANGKA RAYA IN SOLVING TRIGONOMETRY PROBLEMS

2022-06-07T04:22:43+00:00

This research was motivated by the low scores obtained by students in the trigonometry material for the area of triangles in class X GP of SMK Negeri 4 Palangka Raya. In the 2019/2020 school year, only 48% of the 34 students achieved the school's Minimum Completeness Criteria, which is 65. The purpose of this study is to describe the difficulties experienced by students in solving math problems on trigonometry material and the factors that students experience difficulties. This research is a qualitative descriptive study. The results showed that the difficulties experienced by students in solving trigonometry problems were: (a) Difficulties in counting were difficulties in performing number operations. The factor that causes students to be less careful. (b) Difficulty in transferring knowledge, namely determining the formula and sine value. The reason is that students do not understand the material being taught so they cannot distinguish the formula used in determining the area of a triangle according to what is known in the problem. (c) Difficulty in understanding mathematical language, namely understanding mathematical symbols correctly. The reason is that students are less careful in writing down the numbers that match the existing mathematical symbols. (d) Difficulty in visual perception, namely making and understanding sketches or drawings based on existing problems. The reason is that students do not understand how to change what is asked in the question of the shape of a triangular image and vice versa.
