Pengembangan Lembar Kegiatan Peserta Didik (LKPD) Berbasis Multipel Representasi Pada Pokok Bahasan Asam Dan Basa Kelas XI MIA SMA/MA
Development of LKPD based on Multiple Representations on the subject of acids and bases aims to develop teaching materials that are valid and suitable for use in the learning process. The research used the research method Research and Development (R&D) with a 4-D model consisting of 4 stages, namely, Define, Design, Develop, and Disseminate, but in the Multiple Representation-based LKPD development research this only reached the stage develop. The object of this research is teaching materials in the form of LKPD based on Multiple Representations on the subject of acid and base class XI MIA SMA/MA. The Instruments data collection in study this were validation sheets and user response questionnaires consisting of teacher response questionnaires and student response questionnaires. The data analysis technique is by calculating the percentage score of validation assessment and user response questionnaires. The results showed that the LKPD based on Multiple Representations developed met valid criteria based on the aspects of content feasibility, feasibility of multiple representation characteristics, linguistic feasibility, presentation feasibility, and graphic feasibility with an average score of 91%. The LKPD that has been declared valid by the validator is tested one by one on 3 students, and a positive response is obtained. The results of the user response test by 2 chemistry teachers and 20 students were included in the very good criteria with scores of 90.88% and 91% respectively. Based on the results of data analysis and user responses, it can be concluded that LKPD based on Multiple Representations on the subject of acid and base class XI MIA SMA / MA is declared valid and can be used in the chemistry learning process.
