PENERAPAN MODEL PEMBELAJARAN PROBLEM BASED LEARNING (PBL) BERBASIS KEARIFAN LOKAL UNTUK MENINGKATKAN KETERAMPILAN PROSES SAINS PESERTA DIDIK PADA MATERI ZAT ADITIF 

APPLICATION OF A PBL LEARNING MODEL BASED ON LOCAL WISDOM TO IMPROVE STUDENTS' SCIENCE PROCESSING SKILLS ON ADDITIVE MATERIALS

Penelitian ini  bertujuan untuk mendeskripsikan peningkatan keterampilan proses sains peserta didik, keterlaksanaan penerapan model pembelajaran PBL berbasis kearifan lokal, dan respon peserta didik setelah menerapkan model pembelajaran PBL berbasis kearifan lokal. Penelitian ini merupakan penelitian Quasi Experiment dengan menggunakan rancangan percobaan The Only Pretest-Posttest Control Group Design. Sasaran penelitian ini adalah peserta didik kelas VIII A dan VIII B di SMP Negeri 1 Maduran Lamongan. Teknik pengumpulan data melalui tes, observasi, dan angket. Analisis data keterampilan proses sains diperoleh dari hasil pretest dan posttest, analisis data keterlaksanaan pembelajaran diperoleh dari observasi menggunakan skala guttman, dan analisis angket respon peserta didik menggunakan metode skala likert. Hasil penelitian menunjukkan bahwa nilai pretest dan posttest kelas VIII B mengalami peningkatan keterampilan proses sains dengan N-gain sebesar 0,6 dengan kriteria sedang dan pada kelas VIII A sebesar 0,1 dengan kriteria rendah. Keterlaksanaan penerapan model pembelajaran PBL berbasis kearifan lokal di kelas VIII B mendapatkan nilai kappa dari pertemuan pertama, kedua, dan ketiga memperoleh rata-rata baik. Peserta didik memberikan respon dengan kategori baik terhadap penerapan model pembelajaran PBL berbasis kearifan lokal dengan persentase pada masing-masing aspek yaitu minat peserta didik, KPS yang dikaitkan dengan model pembelajaran PBL, dan kepuasan peserta didik berkategori baik, sehingga disimpulkan bahwa penerapan model pembelajaran PBL berbasis kearifan lokal dapat meningkatkan keterampilan proses sains peserta didik pada materi zat aditif.

This research aims to describe the improvement in students' science process skills, the implementation of the local wisdom prroblem based learning model, and the students' responses after implementing the local wisdom-based PBL learning model. This research is a Quasi Experiment research using the Only Pretest-Posttest Control Group Design experimental design. The targets of this research were students in classes VIII A and VIII B at Junior high school 1 of Maduran Lamongan. Data collection techniques through tests, observations and questionnaires. Analysis of data on science process skills was obtained from pretest and posttest results, analysis of learning implementation data was obtained from observations using the Guttman scale, analysis of response questionnaires used the Likert scale method. The research results showed that the pretest and posttest scores for class VIII B experienced an increase in science process skills with an N-gain of 0,6 with medium criteria and for class VIII A of 0,1 with low criteria. The implementation of the PBL learning model based on local wisdom in class VIII B obtained a good average kappa value from the first, second and third meetings. Students responded in the good category to the application of the PBL learning model based on local wisdom with percentages for each aspect, namely student interest, SPS associated with the PBL learning model, and student satisfaction in the good category, so it was concluded that the application of the Problem based learning model Local wisdom can improve students' science process skills in additive material.
