Tesis, Program Studi Magister Teknologi Pendidikan, Fakultas Ilmu Pendidikan, Universitas Negeri Surabaya. Pembimbing: (I) Dr. Fajar Arianto, M.Pd. (II) Dr. Khusnul Khotimah, M.Pd.

Kata Kunci: Discovery Kit Trainer, Problem-Based Learning, Kemampuan Berpikir Sistem, Kemampuan Berpikir Kritis.

Penelitian ini bertujuan untuk mengetahui: (1) pengaruh Discovery Kit Trainer dengan model Problem-Based Learning terhadap kemampuan berpikir sistem; dan (2) kemampuan berpikir kritis siswa pada praktikum Instalasi Penerangan Listrik di SMKN 1 Glagah Banyuwangi. Studi ini menerapkan metode kuantitatif dengan pendekatan eksperimen semu (Quasi-Experimental Design), dengan jenis Nonrandomized Control Group, Pretest–Posttest Design. Penelitian ini menggunakan angket, tes, dan rubrik penilaian untuk mengumpulkan data. Sampel terdiri dari siswa kelas X TKTL 1 (kontrol) dan X TKTL 2 (eksperimen) di SMKN 1 Glagah Banyuwangi. Data diperoleh melalui tes kemampuan berpikir kritis dan sistematis pada praktikum Instalasi Penerangan Listrik, lalu dianalisis dengan uji independent sample.

Hasil penelitian ini menunjukkan bahwa: (1) adanya pengaruh Discovery Kit Trainer dengan model Problem-Based Learning terhadap kemampuan berpikir sistem dengan nilai Asymp. Sig. (2-tailed) sebesar 0,000; dan (2) adanya pengaruh Discovery Kit Trainer dengan model Problem-Based Learning terhadap kemampuan berpikir kritis dengan nilai Asymp. Sig. (2-tailed) sebesar 0,000. Oleh karena itu, dapat disimpulkan bahwa: (1) Discovery Kit Trainer dengan model Problem-Based Learning berpengaruh signifikan terhadap kemampuan berpikir sistem; dan (2) kemampuan berpikir kritis siswa pada praktikum Instalasi Penerangan Listrik.

Penelitian ini menyarankan Discovery Kit Trainer dengan model Problem-Based Learning sebagai pendekatan pembelajaran yang mampu secara efektif mengembangkan kemampuan berpikir sistematis dan kritis siswa, terutama pada kegiatan praktikum Instalasi Penerangan Listrik.

ABSTRACT

Laili, Ayil Qoimatul. 2025. The Influence of Discovery Kit Trainer with a Problem-Based Learning Model on Systems and Critical Thinking Skills in the Electrical Lighting Installation Practicum at SMKN 1 Glagah Banyuwangi. Thesis, Master’s Program in Educational Technology, Faculty of Education, Universitas Negeri Surabaya. Advisors: (I) Dr. Fajar Arianto, M.Pd.; (II) Dr. Khusnul Khotimah, M.Pd.

Keywords: Discovery Kit Trainer, Problem-Based Learning, Systematic Thinking Ability, Critical Thinking Ability.

This study aims to determine: (1) the effect of the Discovery Kit Trainer using the Problem-Based Learning model on students’ systems thinking skills; and (2) students’ critical thinking skills in the Electrical Lighting Installation practicum at SMKN 1 Glagah Banyuwangi.

The study employed a quantitative method with a quasi-experimental design, specifically a Nonrandomized Control Group, Pretest–Posttest Design. Data were collected using questionnaires, tests, and assessment rubrics. The sample consisted of students from class X TKTL 1 (control group) and X TKTL 2 (experimental group) at SMKN 1 Glagah Banyuwangi. Data were obtained through tests measuring systems thinking and critical thinking skills in the Electrical Lighting Installation practicum and analyzed using the independent sample t-test.

The results of the study show that: (1) the Discovery Kit Trainer using the Problem-Based Learning model has a significant effect on systems thinking skills, with an Asymp. Sig. (2-tailed) value of 0.000; and (2) it also significantly affects critical thinking skills, with an Asymp. Sig. (2-tailed) value of 0.000. Therefore, it can be concluded that: (1) the Discovery Kit Trainer using the Problem-Based Learning model has a significant influence on systems thinking skills; and (2) on students' critical thinking skills in the Electrical Lighting Installation practicum.

This study recommends the Discovery Kit Trainer with the Problem-Based Learning model as an effective instructional approach for enhancing students’ systems and critical thinking skills, particularly in practicum-based learning activities such as Electrical Lighting Installation.
