Abstract
Penelitian ini bertujuan untuk mengetahui peningkatan KPS peserta didik melalui implementasi LKPD praktikum berbasis inkuiri terbimbing pada penentuan trayek pH indikator asam basa dari ekstrak leunca. Metode penelitian yang digunakan adalah metode pra eksperimen (pre-experimental research) dengan desain penelitian One-Group pretest-posttest. Penelitian dilakukan di salah satu SMA yang ada di kota Bekasi dengan melibatkan 32 peserta didik sebagai subjek penelitian, 5 validator/ahli sebagai penilai instrumen yang terdiri dari 2 orang dosen Pendidikan Kimia dan 3 orang guru kimia SMA, serta 3 observer penelitian sebagai pengamat dalam penelitian. Instrumen dalam penelitian ini berupa lembar observasi KPS, LKPD dan rubrik jawaban LKPD, butir soal pretest dan posttest, serta angket respons peserta didik terhadap pembelajaran. Hasil uji kelayakan untuk instrumen lembar observasi, modul ajar dan angket respons peserta didik dikategorikan sangat baik. Hasil uji validitas pretest-postest adalah 0,915 dengan kategori validitas tinggi dan uji reliabilitas dengan nilai α sebesar 0,711 dikategorikan reliabel. Hasil penelitian dengan instrumen lembar observasi menunjukkan bahwa dari 11 indikator KPS yang diobservasi semuanya muncul dalam pembelajaran, sedangkan indikator KPS yang muncul berdasarkan jawaban LKPD yaitu 7 dari 11 indikator KPS, yaitu indikator mengajukan pertanyaan, mengajukan hipotesis, merencanakan percobaan, mengamati/observasi, mengelompokkan, menerapkan konsep, dan menafsirkan/interpretasi. Berdasarkan hasil pretest dan posttest, implementasi pembelajaran menggunakan LKPD praktikum berbasis inkuiri terbimbing memberikan peningkatan KPS peserta didik pada penentuan trayek pH indikator asam basa dari ekstrak leunca secara keseluruhan dengan N-Gain sebesar 0,66 dengan kategori sedang. Hasil angket dari respons peserta didik terhadap pembelajaran menggunakan LKPD praktikum berbasis inkuiri terbimbing pada penentuan trayek pH indikator asam basa dari ekstrak leunca dikategorikan sangat baik pada aspek kemudahan menggunakan LKPD, minat belajar, dan kategori baik pada aspek kepuasan belajar. This study aims to determine the improvement of students' Science Process Skills (SPS) through the implementation of guided inquiry-based practicum worksheets on determining the pH range of acid-base indicators from leunca extract. The research method used was pre-experimental research with a one-group pretest-post-test design. The study was conducted at a high school in Bekasi with 32 students as research subjects, 5 validators/experts as instrument assessors (consisting of 2 Chemistry Education lecturers and 3 high school chemistry teachers), and 3 research observers. The instruments used in this study were SPS observation sheets, worksheets and worksheets answer rubrics, pretest and post-test questions, and a student responsse questionnaire on the learning. The feasibility test results for the observation sheet, teaching module and student responsse questionnaire instruments were categorized as very good. The validity test results for the pretest-post-test were 0.915, categorized as high validity, and the reliability test with an α value of 0.711 was categorized as reliable. The results from the observation sheets instrument showed that all 11 observed SPS indicators appeared in the learning process. Meanwhile, based on the worksheets answers, 7 out of 11 SPS indicators appeared: asking questions, formulating hypotheses, designing experiments, observing, classifying, applying concepts, and interpreting. Based on the pretest and post-test results, the implementation of guided inquiry-based practicum worksheets provided an overall improvement in students' SPS in determining the pH range of acid-base indicators from leunca extract, with an N-Gain score of 0.66, which is in the medium category. The results of the student response questionnaire on learning using the guided inquiry-based practicum worksheets for determining the pH range of acid-base indicators from leunca extract were categorized as very good in terms of ease of use and learning interest, and good in terms of learning satisfaction.
