<![CDATA[Penelitian ini bertujuan untuk mengetahui penerapan model pembelajaran kooperatif tutor sebaya dalam meningkatkan hasil belajar siswa kelas X pada mata pelajaran Dasar Listrik Elektronika di SMK Negeri 2 Kupang. Penelitian dilatarbelakangi oleh rendahnya hasil belajar siswa akibat pembelajaran yang masih berpusat pada guru dan kurangnya keterlibatan aktif siswa. Penelitian menggunakan metode Penelitian Tindakan Kelas (PTK) yang dilaksanakan dalam dua siklus, masing-masing terdiri atas tahap perencanaan, pelaksanaan tindakan, observasi, dan refleksi. Subjek penelitian adalah 36 siswa kelas X TITL II SMK Negeri 2 Kupang. Data dikumpulkan melalui tes hasil belajar dan observasi, kemudian dianalisis secara deskriptif kuantitatif dan kualitatif. Hasil penelitian menunjukkan bahwa rata-rata nilai siswa meningkat dari 70,14 pada pra-tindakan menjadi 79,58 pada siklus I dan 90,42 pada siklus II, sedangkan persentase ketuntasan belajar meningkat dari 33% menjadi 84% dan akhirnya mencapai 100%. Aktivitas dan partisipasi siswa selama proses pembelajaran juga mengalami peningkatan pada setiap siklus. Dengan demikian, penerapan model pembelajaran kooperatif tutor sebaya dapat meningkatkan hasil belajar dan aktivitas belajar siswa pada mata pelajaran Dasar Listrik Elektronika dalam konteks kelas yang diteliti. Implementation of the Peer-Tutor Cooperative Learning Model to Improve Learning Outcomes for Grade X Students in the Basic Electricity and Electronics Subject at SMK Negeri 2 Kupang Abstract This study aimed to investigate the implementation of the peer tutoring cooperative learning model in improving the learning outcomes of tenth-grade students in the Basic Electrical and Electronics course at SMK Negeri 2 Kupang. The study was motivated by students' low learning outcomes, which were attributed to teacher-centered instruction and the limited active participation of students in the learning process. This research employed a Classroom Action Research (CAR) design conducted in two cycles, each consisting of the stages of planning, action, observation, and reflection. The research subjects were 36 students of Class X TITL II at SMK Negeri 2 Kupang. Data were collected through learning achievement tests and classroom observations and were analyzed using descriptive quantitative and qualitative methods. The results showed that the students' mean score increased from 70.14 in the pre-action stage to 79.58 in Cycle I and 90.42 in Cycle II, while the percentage of students achieving learning mastery increased from 33% to 84%, and finally reached 100%. Students' learning activities and participation also improved in each cycle. Therefore, the implementation of the peer tutoring cooperative learning model was found to improve students' learning outcomes and learning activities in the Basic Electrical and Electronics course within the context of the classroom studied.]]>
