PENGEMBANGAN LKPD BERBASIS AUGMENTED REALITY PADA MATA PELAJARAN BIOLOGI KELAS XI SMA

Abstract

This study was motivated by the low learning outcomes of students in Biology
learning, particularly on the skeletal system topic, due to the use of conventional
worksheets that were unable to visualize abstract concepts effectively. In addition,
students often experienced difficulties in understanding the structure and functions
of the human skeletal system and showed low engagement during the learning
process. Therefore, this study aimed to develop an Augmented Reality (AR)-based
Student Worksheet (LKPD) for Grade XI Senior High School Biology and to
determine its validity, practicality, and effectiveness. The research employed the
Research and Development (R&D) method using the ADDIE model, which consists
of Analysis, Design, Development, Implementation, and Evaluation stages. The
research subjects included material experts, media experts, Biology teachers, and
36 Grade XI students at SMA Negeri 1 Solok Selatan. Data were collected through
validation sheets, practicality questionnaires, and learning outcome tests. The
results indicated that the developed AR-based LKPD achieved a material validity
score of 96.67% and media validity scores of 95.38% and 93.85%, all categorized
as very valid. The practicality test yielded an average score of 93.01%, indicating
that the product was very practical and easy to use. Furthermore, the effectiveness
test showed a significant improvement in students’ learning outcomes, with an N
Gain score of 97.67%, categorized as highly effective. Based on these findings, the
AR-based LKPD was proven to be valid, practical, and effective for supporting
Biology learning on the human skeletal system in Grade XI Senior High School.
