Abstract – Finding maximal clique is a problem to get a clique with the maximum number of points on a graph, where the selected points are the points that are connected to each other. Finding maximal clique in a graph would be easier if using an algorithm. One of algorithms that can be used to determine the maximal clique is clique algorithm. However, the clique algorithm still has a weakness that the process is a relatively long process because it has two procedures. Therefore, in this study a modification to this algorithm. An algorithm not only must be correct, but also must be efficient. The efficiency of an algorithm is measured from the execution time of the algorithm and the space of memory that is required to run it. After modification is done to clique algoritma, the time of complexity asymptotic algorithm gained is .

This study aims to produce a learning design for flat-sided geometry based on Rejang Lebong ethnomathematics to improve students' mathematical problem-solving skills that are valid, practical, and effective. It is motivated by the low ability to solve students’ mathematical problems. Mathematics learning carried out in schools should involve students actively. The research procedure is guided by the Plomp development design. The development model studied by Plomp is the initial investigation, development, prototyping, and research phases. In the initial investigation phase, the implementation of needs, curriculum, concept, and student analyses was implemented. In the prototype development phase, formative evaluation consists of self-evaluation, one-on-one evaluation, one-on-one evaluation, small group evaluation, and testing. Meanwhile, at the time of its application, it was tested on students of class VIII SMP to see the learning outcomes of the learning problem-solving abilities. Based on the development that has been carried out, it is obtained that the learning design of flat-sided geometry based on the Rejang Lebong ethnomathematics in the form of HLT, teacher's books, and books for class VIII SMP students are valid, practical, and effective.

Students' problemsolving abilities can be improved in one way, namely by choosing the right mathematics learning model. One learning model that can be used is the problembased learning model. The aim of this research is to re-analyze the influence of the problembased learning model on students' mathematical problemsolving abilities by reviewing, summarizing data and analyzing several research results that have been published on Google Scholar as many as 14 articles using statistical methods. The type of research in this article is meta-analysis research. The research steps include data collection, coding, calculating the increase in problem solving abilities and effect size, and drawing conclusions. Based on the research results, the average effect size is 2.02 in the very large category. Based on the average effect size, it can be concluded that the problembased learning model influences students' mathematical problemsolving abilities.

Gaining proficiency in mathematical concepts is a fundamental goal in learning mathematics. However, students' ability to understand mathematical ideas at SMPN 10 Padang is currently inadequate. Applying the Discovery Learning model is an effort to increase student participation in the learning process. This research used quasi-experimental method, specifically using posttest-only non-equivalent control group design. The t-test data analysis resulted in a P-value of 0.013 which indicates that the Discovery Learning model is superior to the direct learning model in class IX SMPN 10 Padang.Keywords– Discovery Learning, Understanding Mathematical Concepts
