Abstract
This study aims to improve students' critical thinking skills through the application of the Problem Based Learning (PBL) learning model in the Light Vehicle Electrical Maintenance (PKKR subject in class XI TKR SMK Negeri 3 Tangerang Regency. This study is a Classroom Action Research (CAR) conducted in two cycles using the Kemmis and McTaggart model, with stages of planning, action, observation, and reflection. Data collection techniques include observation, tests (pretest and Posttest), and Esai questions based on case studies. The results showed a significant increase in students' critical thinking skills. The average critical thinking assessment score increased from 2.14 in cycle I to 3.45 in cycle II, with 26 out of 29 students (89.66%) experiencing an increase. The average pretest score of 4.00 increased to 5.66 in the Posttest of cycle I, and increased again to 8.90 in the Posttest of cycle II. The average increase from pretest to posttest was 75.00% in cycle I and increased significantly to 223.28% in cycle II. Individually, 26 out of 29 students (89.66%) experienced an increase in scores from pretest to posttest in cycle II. Furthermore, the average score on students' Esais also increased from 1.32 in cycle I to 3.09 in cycle II, with all students experiencing an increase. This indicates that the PBL model has a significant impact on students' critical thinking skills, both through objective tests and case study-based Esais. Therefore, the research success indicator, which is at least 75% of students experiencing an increase in critical thinking skills, is stated to have been achieved and significantly exceeded. This statement indicates that the Problem Based Learning model has proven effective in vocational learning, as it is able to hone critical thinking skills that are in line with the demands of the workplace, especially in the automotive sector.

| Additional Information: | Penelitian ini bertujuan untuk meningkatkan kemampuan berpikir kritis siswa melalui penerapan model pembelajaran Problem Based Learning (PBL) pada mata pelajaran Pemeliharaan Kelistrikan Kendaraan Ringan (PKKR) di kelas XI TKR SMK Negeri 3 Kabupaten Tangerang. Penelitian ini merupakan Penelitian Tindakan Kelas (PTK) yang dilaksanakan dalam dua siklus menggunakan model Kemmis dan McTaggart, dengan tahapan perencanaan, tindakan, observasi, dan refleksi. Teknik pengumpulan data meliputi observasi, tes (pretest dan Posttest), serta soal esai berbasis studi kasus. Hasil penelitian menunjukkan adanya peningkatan yang signifikan pada kemampuan berpikir kritis siswa. Rata-rata skor penilaian berpikir kritis meningkat dari 2,14 pada siklus I menjadi 3,45 pada siklus II, dengan 26 dari 29 siswa (89,66%) mengalami peningkatan. Rata-rata skor pretest sebesar 4,00 meningkat menjadi 5,66 pada Posttest siklus I, dan meningkat lagi menjadi 8,90 pada Posttest siklus II. Rata-rata peningkatan dari pretest ke Posttest adalah 75,00% pada siklus I dan meningkat secara signifikan menjadi 223,28% pada siklus II. Jika dilihat secara individu, sebanyak 26 dari 29 siswa (89,66%) mengalami peningkatan skor dari pretest ke Posttest pada siklus II. Selain itu, skor rata-rata esai siswa juga meningkat dari 1,32 pada siklus I menjadi 3,09 pada siklus II, di mana seluruh siswa mengalami peningkatan. Hal ini menunjukkan bahwa model PBL berdampak nyata terhadap kemampuan berpikir kritis siswa, baik melalui tes tujuan maupun esai berbasis studi kasus. Dengan demikian, indikator keberhasilan penelitian yakni minimal 75% siswa mengalami peningkatan kemampuan berpikir kritis dinyatakan tercapai dan terlampaui secara signifikan. Pernyataan ini menunjukkan bahwa model pembelajaran Problem Based Learning terbukti efektif digunakan dalam pembelajaran vokasional, karena mampu mengasah keterampilan berpikir kritis yang sesuai dengan tuntutan dunia kerja, terutama dalam sektor otomotif. | |||||||||
