Pengembangan e-LKPD Berbasis Etnosains Pada Materi Asam Basa

Authors

Abstract

This study aims to develop and determine the feasibility of an ethnoscience-based e-LKPD

derived from traditional Nias medicine on acid–base reaction material, as well as to analyze

students’ responses to the developed e-LKPD. The method used is Research and Development

(R&D) with the ADDIE model. The subjects of this study consisted of two material experts

with assessment indicators including content feasibility, presentation feasibility, and language

feasibility; two media experts assessing the presentation of the e-LKPD, graphic feasibility,

images, illustrations and videos, display quality, and software engineering aspects. In addition,

one chemistry teacher evaluated the e-LKPD design, and 30 students of class XI-5 at SMA

Negeri 53 Jakarta assessed indicators of guidance and information, multimedia material, media

design and facilities, pedagogical eﬀects, and integration of ethnoscience in the e-LKPD. The

results showed that the e-LKPD was developed based on Nias ethnoscience, specifically

traditional medicine used to treat gastritis, following the ADDIE model. Validation by media

experts showed that the Presentation indicator scored 95%, Graphic Feasibility 86%,

Images/Illustrations/Videos 95%, Display Quality 88%, and Software Engineering 93%, with

an average of 91%, categorized as very good. Validation by material experts showed that

Content Feasibility scored 84%, Presentation Feasibility 87%, and Language Feasibility 89%,

with an average of 86%, also categorized as very good. Student response analysis showed that

the Guidance and Information aspect scored 83%, Multimedia Material 83%, Media Design

and Facilities 84%, Pedagogical Eﬀects 83%, and Ethnoscience Integration 82%, with an

overall average of 83%. These results indicate that the ethnoscience-integrated e-LKPD based on

traditional Nias medicine is categorized as very good. Therefore, the developed

ethnoscience-based e-LKPD is feasible to be used as a learning medium for acid–base reaction

material. The implications of this study serve as a reference for developing other

ethnoscience-based e-LKPDs relevant to chemistry education.
