Characteristics of chemical materials are (1) Abstract, (2) Complex and multidisciplinary, (3). Involves analytical arithmetic operations. The transition from high school to university level is a learning process that is quite difficult if it is not accompanied by the right understanding. Understanding the concept of chemical materials obtained from high school, when studied at the university level, different meanings are obtained. This different understanding is what we often call misconceptions. Therefore, to find out the misconceptions that occur in students is a necessity and need for lecturers or teachers, so that they can be used as guidelines and guidance to deal with these misconceptions. This study was conducted to identify the percentage level of difficulty and general chemistry misconceptions for students of mathematics education at the University of HKBP Nommensen, using a random sampling technique. This research was carried out in 5 stages, namely (1). Creating a four-tier test diagnostic instrument; (2) Judgment of instruments by experts; (3) Data collection and interviews (4). Data processing and analysis, (5). Conclusion. Based on the results of data analysis and identification results in this study, the category of student conceptions in the Acid-Base solution material is the percentage of students who experience several categories of conception, namely understanding concepts, understanding partially, misconceptions, not understanding concepts and cannot be coded. The percentage of these categories is as follows; 24% of students fall into the category of understanding concepts, 32% of students fall into the category of partial understanding, 11% of students fall into the category of misconceptions, 30% of students fall into the category of not understanding concepts and 2% of students fall into the category of not being able to code, which means that not all students answered all the questions in the four-tier diagnostic test instrument. There are 2% who did not answer the four-tier diagnostic test.

The low students’ achievement, lack of variety of teaching methods on Basic Chemistry, lack of students’ engagement on teaching and learning process, misconception of Chemistry is difficult subject, and the changes of curriculum into KKNI on Industrial Revolution 4.0 that demand for the students are on the level 6 on the output based on the government legislation are the problems that need to be done on this study. This study aimed to find out the students’ achievement and response during the learning process on Basic Chemistry-Solubility and Solubility Product-class by using SETS approach based on KKNI. This is a quasi experiemental study through the distance learning. The technique of collecting the data was documentation and research instruments that consist of course outlines (RPS), students’ activity (observation sheet), and students’ work sheets that describe the activity with SETS method, pretest and post test, and the student’s questionnaire. The results showed that the implementation of SETS approach affects the students achievement thus there is enhancement on students achievement for the control and experimental class for 51.92% and the students response on the methods are 88%. The Concluded that there is an effect of Using SETS to improve student achievement and increasing student responses to learning. Keywords: SETS, KKNI, Ksp, student achievement

Program Kerjasama dalam Pengabdian Kepada Masyarakat ini ditujukan agar dapat menggiatkan literasi matematika bagi siswa–siswi di SMP HKBP Sidorame Medan. Melakukan pendampingan pemberian informasi kepada siswa-siswi maupun guru-guru pentingnya menerapkan literasi sejak dini bagi siswa–siswi SMP mengingat rendahnya keinginan untuk membaca siswa–siswi saat sekarang ini, serta hal ini juga sangat bermanfaat untuk pengembangan pengetahuan di segala lapisan masyarakat. Program Kerjasama Pengabdian Masyarakat ini dilakukan oleh Dosen dan Mahasiswa dari Program Studi Pendidikan Matematika Fakultas Keguruan dan Ilmu Pendidikan Universitas HKBP Nommensen Medan dengan Mahasiswa dari Czech University. Program Kerjasama ini dilaksanakan pada tanggal 25 Juli 2022 serta berakhir pada tanggal 26 Juli 2022. Tradisi lisan yang masih sangat kuat, pendidikan sekolah yang sistemnya masih belum melakukan aktivitas–aktivitas yang maksimal untuk menggiatkan tradisi literasi matematika kepada siswa–siswinya, addicted–nya dengan pemakaian gadget akibat dari terjadinya pandemi covid-19, merupakan beberapa penyebab rendahnya literasi matematis pada siswa–siswi di Indonesia, dimana hal ini juga terjadi pada siswa-siswi di SMP HKBP Sidorame Medan. Dari beberapa masalah ini dicoba untuk melakukan kegiatan pengabdian masyarakat dengan aktivitas berbeda yang belum pernah dilakukan di sekolah tersebut yaitu dengan melibatkan pendampingan beberapa mahasiswa dari Czech University dengan harapan dapat menggugah siswa–siswi dalam meningkatkan keinginannya dalam melakukan literasi. Program Kerjasama ini menjadi salah satu aktivitas penting dalam peningkatan kegiatan literasi matematis di sekolah. Hal positif lain adalah terdapatnya dalam jumlah yang cukup besar kelompok yang teridentifikasi minim literasi matematis, tidak hanya kelompok siswa-siswi, kelompok guru juga. Maka guru-guru juga harus membuat aktivitas kreatif yang membuat literasi matematis menjadi suatu budaya bagi siswa-siswinya.

Currently, many students do not understand the values of Pancasila well and deeply. So, it is necessary to carry out activities at the Berastagi Christian High School with the theme of the student movement for good practice habits to realize the profile of Pancasila students through learning based on local wisdom. The activity was carried out through four stages, namely seven minutes with God, We Save The World (class cleanliness), Team Work (safety in class), and socialization of the Geogebra software. The results show an increase in students' understanding and appreciation of Pancasila values and local wisdom. In addition, this activity also assists students in developing good attitudes and behavior through the habituation of good practices carried out in daily activities at school.

Implementing online learning in a higher education environment requires an analysis of learning outcomes and their impact on students, lecturers, and the institutions that administer the learning. The implementation of online learning shows that the learning process takes place and the readiness of lecturers and students to implement online learning. The impact given by online learning is in the form of GPA and student perceptions of the learning process they experience. Based on the research results, various findings were obtained, including that mastery of online learning LMS was not optimal, learning outcomes in the form of GPA were relatively high, students' perceptions of online learning were still low, especially in terms of lecturer readiness and students' confidence in their competence after participating in learning.
