PENERAPAN MODEL PEMBELAJARAN PROBLEM BASED LEARNING BERBASIS KEARIFAN LOKAL UNTUK MENINGKATKAN HASIL BELAJAR SISWA PADA MATERI ZAT ADITIF 

APPLICATION OF LOCAL WISDOM BASED PROBLEM BASED LEARNING MODEL TO IMPROVE STUDENT LEARNING OUTCOMES ON ADDITIONAL SUBSTANCES

Tujuan dalam penelitian ini yaitu untuk mendeskripsikan keterlaksanaan pembelajaran, peningkatan hasil belajar dan respons peserta didik terhadap model pembelajaran Problem Based Learning berbasis kearifan lokal. Jenis penelitian yang digunakan yaitu Pre-experimental design dengan menggunakan desain penelitian One Group Pretest and Posttest Design. Penelitian diuji cobakan kepada siswa kelas VIII-G SMPN 34 Surabaya yang berjumlah 34 siswa pada semester ganjil tahun pelajaran 2021/2022. Teknik pengumpulan data menggunakan tes, angket, dan observasi. Keterlaksanaan pembelajaran menggunakan model pembelajaran Problem Based Learning berbasis kearifan lokal memiliki rata-rata penilaian pada pertemuan pertama yaitu 94,31% dan pada pertemuan kedua 100%. Hasil belajar dapat diketahui pada peningkatan nilai pretest dan posttest  dengan rata-rata skor N-Gain 0,69 yang berkategori sedang. Hasil analisis effect size menunjukkan keefektifan penerapan Problem Based Learning berbasis kearifan lokal sebesar 3,20 dengan kriteria sangat tinggi. Respons positif diberikan peserta didik dalam menerapkan Problem Based Learning berbasis kearifan lokal dengan persentase rata-rata 97,93%. 

The purpose of this research is to describe the implementation of learning process, improving learning outcomes and students response by using Problem Based Learning model based on local wisdom science class of second grade at junior high school. The type of research used Pre-experimental design and the research design used One Group Pretest-Posttest Design. This research was implemented to student on class VIII-G as many as 34  students at Junior High School 34 Surabaya in the 2021/2022 academic year. Data collection techniques using tests, questionnaires, and observations. The instrument of this research are test sheets in the form of pretest and posttest, students response questionnaires observation sheets. The implementation of learning using the Problem Based Learning model based on local wisdom has an average assessment at the firt meeting obtained a percentage of  94,31% and second meeting 100%. Learning outcomes can be seen in the increase of pretest and posttest which get average N-Gain scores 0,69 which was included moderate category. Then the results of the effect size analysis show that the effectivity of the Problem Based Learning model based on local wisdom is 3,20 with strong effect. The students gave a positive response to the application of the Problem Based Learning model based on local wisdom with an average percentage of 97,93%.
