Abstract

This community service activity aimed to strengthen students’ understanding of  the combinatorics concepts in facing the regency-level of National Science Competition (KSN) in field of mathematics in 2021. The activity was carried out in March-April 2021 for six meetings in the form of training/coaching. The training used both discovery and drilling methods. The location of the activity was at SMAN 1 Muara Batu, North Aceh Regency with four students as the subject who have been selected at the school level and selected to participate in the KSN at the regency level. Data analysis was carried out qualitatively by direct observation to observe the improvement of the students’ comprehension during the learning process. The result obtained was an improvement of the students’ understanding of combinatorics topic. It can be seen in solving problems, the students are able to determine what concepts will be used and able to solve several KSN questions on combinatorics topic.

Abstract

This community service activity aimed to improve students’ ability in solving algebra’s problems in National Science Competition (KSN) in field of mathematics especially in topic of inequalities related to quadratic mean, arithmetic mean, geometrics mean, and harmonic mean. The activity was in the form of teaching concepts to three students who will participate in KSN at district level. The activity was carryout at Iskandar Muda private high school, north Aceh regency, Aceh Province. The community service method used both expository and drilling methods. Data analysis was carried out qualitatively by observing directly changes in students’ ability in solving algebraic problems given during the teaching process. The results obtained of the community service were an increase in students’ ability to apply concept of inequality related to the quadratic mean, arithmetic mean, geometrics mean, and harmonic mean in solving algebraic problems. The results can be an important thing for the students in facing KSN at the district level.
