Pengembangan Lembar Kegiatan Peserta Didik (LKPD) Berbasis Model Inkuiri Terbimbing Pada Pokok Bahasan Kesetimbangan Ion Dan Ph Larutan Penyangga Kelas XI SMA/MA
This development research aims to develop a LKPD based on a guided
inquiry model on the subject of ion balance and pH of a valid buffer solution. This
research is a development research (R&D) with the ADDIE model which has 5
stages of development, namely analysis, design, development, implementation,
and evaluation. This research was carried out until the development stage. The
object of this research is teaching materials, namely Student Activity Sheets
(LKPD) based on the guided inquiry model. The data collection instrument is a
validation sheet given to three validators, the results of data analysis obtained
validity on the aspect of content feasibility, aspects of the characteristics of the
guided inquiry model, aspects of linguistic feasibility, aspects of presentation
feasibility, and aspects of graphic feasibility, respectively, amounting to 91.66%,
93.34%, 94.45%, 95.83% and 95.83% obtained an average validation of the five
aspects of 94.22% with a valid feasibility category. The result of LKPD
assessment by 3 teachers as users was obtained a percentage of 90.95% with very
good criteria, meaning that the LKPD that had been developed was suitable for
use in learning. Based on a limited trial that has been conducted on 20 students, a
response of 89.46% was obtained with very good criteria.
