Penerapan Model Pembelajaran Problem Based Learning (PBL) untuk Meningkatkan Pengetahuan Siswa pada Materi Keselamatan dan Kecelakaan Kerja (K3) di SMK Negeri 1 Dlanggu

The Application of Problem-Based Learning (PBL) Learning Model to Improve Students' Knowledge on Occupational Safety and Accident Material at Smk Negeri 1 Dlanggu

Salah satu permasalahan pada proses pembelajaran yaitu masih banyak peserta didik yang cenderung bersikap pasif selama kegiatan pembelajaran karena guru masih dianggap sebagai sumber utama dalam pembelajaran. Proses pembelajaran akan terasa membosankan,  hasilnya siswa banyak yang sibuk sendiri, mengantuk, bercanda dengan temannya, bahkan bermain gadget.

Tujuan dari penelitian ini, yaitu; (1) mengetahui keterlaksanaan sintaks, (2) mengetahui aktivitasi siswa, (3) mengetahui respon siswa, serta (4) mengetahui pengaruh pembelajaran problem based learning terhadap peningkatan pengetahuan siswa. Model pembelajaran Problem Based Learning (PBL) menerapkan gaya belajar Student Centered atau pembelajaran yang berfokus pada siswa sehingga guru hanya sebagai fasilitator. Penelitian ini hanya berfokus pada peningkatan pengetahuan atau kognitif, dimana aspek pengetahuan berorientasi pada mengembangkan kemampuan berpikir yang mencakup kemampuan intelektual mulai dari mengingat sampai memecahkan masalah.

Metode penelitian ini adalah kuantitatif dengan jenis penelitian experimental serta rancangan penelitian berupa control group pretest-posttest design. Teknik analisis data menggunakan uji t.  Hasil analisis data mendapatkan perbedaan rata-rata antara nilai pretest sebesar 65,71 dan posttest sebesar 86.82 serta didukung dengan pengujian hipotesis menggunakan Uji Independen t-test yang mendapatkan hasil 0.035, dimana signifikasi tersebut < 0.05 yang berarti H0 ditolak dan Ha diterima sehingga dapat disimpulkan bahwa model pembelajaran problem based learning dapat meningkatkan pengetahuan siswa.

One of the problems in the learning process is that there are still many students who tend to be passive during learning activities because the teacher is still considered the main source of learning. The learning process will feel boring, the result is that many students are busy on their own, sleepy, joking with their friends, even playing gadgets.

The objectives of this study, namely; (1) to know the implementation of syntax, (2) to know student activity, (3) to know student responses, and (4) to know the effect of problem-based learning on increasing student knowledge. The Problem Based Learning (PBL) learning model applies a Student Centered learning style or learning that focuses on students so that the teacher is only a facilitator. This research only focuses on increasing knowledge or cognitive, where the knowledge aspect is oriented towards developing thinking skills that include intellectual abilities ranging from remembering to solving problems.

This research method is quantitative with experimental research type and research design in the form of control group pretest-posttest design. The data analysis technique uses the t test. The results of data analysis get an average difference between the pretest score of 65.71 and the posttest of 86.82 and are supported by hypothesis testing using the Independent t-test which gets a result of 0.035, where the significance is <0.05 which means H₀ is rejected and H_a is accepted so it can be concluded that the problem-based learning model can increase student knowledge.
