Abstract

Background of this research is a unmotivated student in the learning process, which made score of scientific performance in science subject for Junior Highschool grade VIII to IX was low. The purpose of this study was to analyze the effect of conventional learning models (Teacher Centered Learning) and project-based learning models (Project Based Learning), which to know how deep the development of value in scientific performance and student character review on chemical daily product materials. The type of research used is experimental research with the form of experimental design, namely Pre-Experimental Design Intact-Group Comparison. The subjects of this study were 69 students in three classes. The sampling technique in this study used a purposive sampling technique and a proportional sampling technique. The instrument used was observation to measure how much development the value of scientific performance was as well as a review of the student's character in the TCL and PBL learning models. The results showed an increase in the percentage of scientific performance values for each indicator, namely the observation indicator on TCL 52% increased to 94.44% on PBL, planning indicator on TCL 46% increased to 93.53% on PBL, indicator implemented on TCL 78% increased to 89.81% on PBL, indicators communicating on TCL 51% increased to 95.37% on PBL, indicators concluded on TCL 73% increased to 89.81% on PBL, and product yield indicators on TCL 55% increased to 97 .22% on PBL. Likewise, in the review of increasing student character values on each indicator of curiosity, hard work, responsibility, communicativeness, creativity, and environmental care, TCL increased after the implementation of PBL. It can be concluded that the Project Based Learning model can develop the value of scientific performance in science subjects for grade VIII to IX junior high school students in Jakarta./Penelitian ini dilatarbelakangi oleh kurang aktifnya siswa pada proses belajar, sehingga rendahnya nilai kinerja ilmiah pada mata pelajaran IPA SMP kelas VIII-IX. Tujuan penelitian ini adalah menganalisis pengaruh model pembelajaran konvensional (Teacher Centered Learning) dan model pembelajaran berbasis proyek (Project Based Learning), sehingga mendapatkan seberapa besar pengembangan nilai kinerja ilmiah dan peninjauan karakter siswa pada materi produk keseharian berbahan kimia. Jenis penelitian yang digunakan adalah penelitian eksperimen dengan bentuk desain eksperimen yang digunakan yaitu Pre-Experimental Design jenis Intact-Group Comparison. Subjek penelitian ini adalah 69 siswa dalam tiga kelas. Teknik pengambilan sampel dalam penelitian ini menggunakan teknik purposive sampling dan teknik proportional sampling. Instrumen yang digunakan adalah observasi untuk mengukur seberapa besar pengembangan nilai kinerja ilmiah serta peninjauan karakter siswa pada model pembelajaran TCL dan PBL. Hasil penelitian menunjukkan adanya peningkatan presentase nilai kinerja ilmiah untuk setiap indikator, yaitu indikator observasi pada TCL 52% meningkat menjadi 94,44% pada PBL, indikator merencanakan pada TCL 46% meningkat menjadi 93,53% pada PBL, indikator melaksanakan pada TCL 78% meningkat menjadi 89,81% pada PBL, indikator mengkomunikasikan pada TCL 51% meningkat menjadi 95,37% pada PBL, indikator menyimpulkan pada TCL 73% meningkat menjadi 89,81% pada PBL, dan indikator hasil produk pada TCL 55% meningkat menjadi 97,22% pada PBL. Demikian juga pada tinjauan peningkatan nilai karakter siswa pada setiap indikator rasa ingin tahu, kerja keras, tanggung jawab, komunikatif, kreativitas, dan peduli lingkungan pada TCL mengalami peningkatan setelah diterapkannya PBL. Dapat disimpulkan bahwa model pembelajaran Project Based Learning dapat mengembangkan nilai kinerja ilmiah pada mata pelajaran IPA siswa kelas VIII-IX SMP di Jakarta.
