LKPD (Student Worksheet) Based on Interactive Augmented Reality (IAR): As a Solution & Variation for Abstract Learning Media to Become Concrete in Junior High School

Abstract

This study aims to develop LKPD on the human digestive system material to determine the feasibility of the product, to determine the assessment of science teachers and student assessments. This study uses the R&D development method using the 4D (Four-D) development model with stages; (1) Define, (2) Design, (3) Develop, and (4) Disseminate. Data collection using material & media expert validation questionnaires, science teacher assessment questionnaires, and student assessment questionnaires. The trial subjects were grade VIII students of SMP Muhammadiyah Kuala Tungkal. The results show that the LKPD product based on Interactive Augmented Reality (IAR) using android on the human digestive system material is feasible to use in the learning process. The results of the LKPD feasibility were obtained from the results of validation by material experts and media experts, material validation was carried out in three stages with a percentage of 100% with the category "Very Feasible" and media validation was carried out in two stages with a percentage of 95% with the category "Very Feasible". The results of the assessment of science subject teachers were obtained with a percentage of 85% with the category "Very Eligible". The results of the assessment of students in the small group trial were obtained with a percentage of 81% with the category "Very Eligible", and the large group trial was obtained with a percentage of 84% with the category "Very Eligible". Based on the results obtained, it can be concluded that the development of LKPD based on Interactive Augmented Reality (IAR) using Android is feasible to be used as a media and teaching material for the subject of the human digestive system for class VIII of junior high school.
