PENINGKATAN KETERAMPILAN PROSES SAINS MENGGUNAKAN LEMBAR KERJA PESERTA DIDIK BERBASIS INKUIRI TERBIMBING PADA MATERI PESAWAT SEDERHANA

INCREASING SCIENCE PROCESS SKILL USING STUDENT WORKSHEET GUIDED INQUIRY BASE LEARNING ON A SIMPLE PLANE MATERIALS

Penelitian ini bertujuan untuk mendeskripsikan pengaruh penggunaan LKPD berbasis inkuiri terbimbing terhadap peningkatan keterampilan proses sains dalam materi pesawat sederhana. Metode penelitian ini menggunakan Pra-Eksperimental dengan desain one group Pre-test and Post-test  yang sasaran penelitian yaitu 18 siswa kelas VIII-B SMPN 40 Surabaya. Data yang diperoleh dengan metode pre experimental design dengan instrumen RPP, LKPD, lembar keterlaksanaan pembelajaran, Lembar pre-test post-test, dan angket respon kemudian dianalisis secara deskripsi kuantitatif. Hasil penelitian menunjukan keterlaksanaan pembelajaran selama dua pertemuan mendapat rata-rata kriteria sangat baik dan sangat praktis. Keterampilan proses sains yang dilatihkan berupa merumuskan masalah, mengidentifikasi variable, membuat hipotesis, melakukan percobaan, menganalisis data, menyimpulkan data, dan mengomunikasikan data. Peningkatan terjadi dalam setiap keterampilan proses sains yang dilatihkan. Rata-rata nilai N-Gain yang didapatkan dari pre-test dan post-test sebesar 0,75 yang berkategori tinggi dan efektif. Siswa memberikan respon sebesar 91,6% dikaterogikan sangat baik. Berdasarkan uraian diatas, dapat disimpulkan bahwa pembelajaran dengan menggunakan LKPD berbasis inkuiri terbimbing dapat meningkatkan keterampilan proses sains pada materi pesawat sederhana.

Kata Kunci: LKPD, inkuiri terbimbing, keterampilan proses sains

The study aimed to describe the impact of the use of guided inquiry-based student worksheet towards improving the scientific process skills in simple machine materials. The method of this research uses pre-experimental with the design of one group pre-test and post-test which the research targets were 18 students of class VIII-B junior high school 40 Surabaya. The data obtained by expertimental designt with instrument learning plant, student worksheet, learning implementation sheet, pre-test post test sheet, and student response questionnaire that are analyzed in quantitative descriptions. The results of the study showed that the implementation of learning during two meetings got an average of very good criteria and very practical. The target skiller is science process involved formulating problems, identifying variables, hypothesizing, experimenting, analyzing data, concluding data, and communicating data. An improvement occurred in any trained scientific process skill. The average N-Gain value obtained 0,75 from pre-test and post-test which was categorized high and effective. Students gave a response of 91.6% which was categorized very good. To sum up learning by using guided inquiry-based LKPD can improve science process skills on simple machine materials.
