PENGEMBANGAN LKPD BERBASIS AUGMENTED REALITY DALAM METODE PRAKTIKUM MATERI ORGAN INDERA UNTUK MENINGKATKAN HASIL BELAJAR SISWA DAN KETERAMPILAN PROSES SAINS

Abstract

Abstract

Sensory organ materials are abstract and difficult to visualize, while the physical torso models available in schools are limited, making practicums less meaningful. This study aimed to develop an Augmented Reality (AR)-based Student Worksheet (LKPD) for sensory organ practicum and to analyze its effect on learning outcomes, science process skills, and student responses. The study employed a Research and Development (R&D) method with the ADDIE model (analysis, design, development, implementation, evaluation) and a non-equivalent control group design. The research was conducted at MAN 3 Cirebon from April to September 2022, with class XI MIA 4 as the experimental group and XI MIA 5 as the control group. Data were collected through expert validation sheets, pretest-posttest, science process skills observation sheets, and student response questionnaires, then analyzed using N-Gain and t-tests. The results showed an average LKPD validation score of 93.4% (very valid) with 96.3% implementation practicality (very practical). The mean N-Gain of learning outcomes in the experimental class was 56.6% (medium category), considerably higher than the control class at 12.2% (low category). The mean science process skills score in the experimental class reached 92.62, higher than the control class at 74.73. Student responses to the AR-based LKPD were also positive, with a questionnaire reliability of Cronbach's Alpha 0.871. In conclusion, the AR-based LKPD is feasible and effective in improving students' learning outcomes and science process skills on sensory organ material, and has potential for application to other abstract biology topics.
