Abstract

ABSTRACTThis study aims to generate and measure the value of the validity and practicality of the E-LKPD buffer solution. E-LKPD is prepared based on a guided inquiry model. The type of research used is Research and Development using the plomp development model. The research instrument was a content and construct validity sheet as well as a practicality questionnaire. The E-LKPD was validated by 2 chemistry lecturers at Padang State University and 1 chemistry teacher, as well as a practicality test (field test) through 15 students of class XI SMAN 4 Padang. The results of the study found that the guided inquiry-based worksheets had a high level of category validity (V=0.91) and the practicality level of students with a very practical category on the score (NP=90%). This research is recommended for further research in terms of testing the effectiveness of the products that have been developed.Keywords: Guided Inquiry, E-LKPD, Buffer Solution, Plomp ABSTRAKPenelitian ini bertujuan untuk menghasilkan serta mengukur nilai validitas dan praktikalitasE-LKPD larutan penyangga.

Abstract

This study aims to produce STEAM-PjBL (Science, Technology, Engineering, Art and Mathematics-Project Based Learning) integrated LKPD on the material of Molecular Forms and determine the level of validity and practicality of the resulting LKPD. This research is a Research and Development (R&D) research using a 4-D model which consists of four steps: define, design, develop, disseminate. This research is limited to the design stage. The research instrument is a validity sheet and a practical sheet. The LKPD was validated by 6 validators consisting of 3 chemistry lecturers from FMIPA UNP and 3 chemistry teachers at SMA N 14 Padang. The LKPD was tested by 3 chemistry teachers and 30 students in class XI MIPA 5 SMA N 14 Padang. The validity data used the Aiken's v Scale and the practical data used a comparison of the students' scores with the maximum scores of students. The average Aiken's v scale is 0.89 with a very valid category. While the practicality of teachers and students obtained NP values of 0.90 and 0.87 with very practical categories.
