Learning is a process of interaction between students and teachers, with lesson materials, delivery methods, learning strategies and learning resources in a learning environment. The success of learning can be seen through the level of success in achieving educational goals. Education is a conscious and planned effort to create a learning atmosphere and learning process so that students actively develop their potential to have religious spiritual strength, self-control, personality, intelligence, noble character, and skills needed by themselves, society, nation and state, and have global mindset. The implementation of learning with the case method model is carried out to overcome the problems that arise as a result of the Limited Face-to-face Learning (PTMT) policy, such as less active student learning activities, low student learning responses and low student learning outcomes. Junior high school students belonging to the Generation Z category have an attitude of openness, this generation accepts various views and mindsets, causing them to easily accept diversity and differences in views. As a result, Gen Z becomes difficult to define themselves, selfidentity changes based on the factors that influence their thinking. Therefore, it is very important to restore national identity or introduce the cultural identity of the surrounding community so as not to be eroded by the development of the outside world which makes generation Z forget local culture, one of which is the Mandailing Tribe Culture in North Sumatra. The development research uses the ADDIE Model by integrating the Local Culture of the Mandailing Tribe in North Sumatra in developing the Mathematics LKPD for Grade VII Junior High Schools based on students' initial perceptions of the current condition of Generation Z. The use of the Case Method approach aims to improve students' critical thinking skills based on the cases presented in the teaching materials.

The government policy in March 2020 regarding the application of online learning has significant changes in the learning process on campus. One of them is by changing teaching materials from textbooks to e-books, which is a must as a form of adjustment related to campus conditions that implement full online learning using LMS SIPDA. The objectives of this study are: (1) Producing an interactive e-book on basics statistics based on Realistic Mathematics assisted by the SIPDA LMS developed by using a valid and practical Kvisoft Flipbook Maker (2) To determine the effectiveness of the e-book Basics of Statistics in improving student problem-solving abilities. This type of research is Research and Development with the ADDIE development model, namely analysis, design, development, implementation, and evaluation. E-book development using the Kvisoft Flipbook Maker Application. The results of the e-book development at the needs analysis stage showed that 85% of students needed integrated learning media. SIPDA integrated e-books can increase student attendance and activities by 60%. At the product design stage, the e-book in the form of a word file is converted into a PDF file and then developed using Kvisoft Flipbook Maker by adding videos, images, and other files. The e-book is validated with a validity rate of 92% by material experts and 89% by media experts. The value of practicality is seen from two things, namely: (1) Questionnaire for responses from media experts and two practitioner lecturers, it was found that the e-book developed could be applied in the good category (3.92) and met the practical criteria (80%) used in the online learning era. (2) The student response questionnaire in a small group of 10 people obtained the category Good (3.96) and very practical (85%). The percentage of student response questionnaire results at the implementation stage of the SIPDA class showed a positive response of 87.6%. The effectiveness aspect is seen from the average individual learning completeness of 71.42 with classical completeness criteria obtained by 91. And the N-Gain score was 0.71 in high category.

This Classroom Action Research aims to minimize the low activity and mathematics learning outcomes of Binjai 14 Public Middle School students in the matter of the Two-Variable Linear Equation System (SPDLV). The recipients of the action were class VIII 2 students at SMP Negeri 14 Binjai with a total of 32 students. The data collection technique for this action was carried out in a qualitative descriptive way through the cycle stages with two rounds where each round consisted of two meetings. The results of this study are increased activity and student learning outcomes by using the cooperative learning model of the Teams Games Tournament (TGT) type. From the results of the initial test data obtained 28 students (87,5%) of 32 students with an average of 50,29%. The results of data analysis in cycle I after the cooperative learning model of the Teams Games Tournament (TGT) type showed that the number of students who achieved mastery learning was 25 students (78,12%) out of 32 students with a class average of 75%. In cycle II, 28 students (87,5%) achieved a mastery level with a class average of 80,79%. There was an increase from cycle I to cycle II. Likewise with student activities while learning took place in cycle I, the number of students who had a percentage of activity ≥ 70% classically was 2 students (6.25%) of 32 students and at the end of cycle II it increased to 28 students (87,5%). The classical increase in activity from cycle I to cycle II was 30%. So this study concluded that through the TGT learning model it can increase students' activity and learning outcomes in mathematics.
