The mental reconstruction model of students is essential to see the progress and difficulties of students in understanding chemical material, especially at the level of macroscopic, submicroscopic, and symbolic representations. This study aims 1) to see how the influence of Augmented Reality (AR) based learning media with the concept of representation, 2) to see the validity, practicality and effectiveness of the development of augmented reality-based representational chemistry textbooks, and 3) to analyze the mental models of students. The research method used is a literature study (literature study) with qualitative and quantitative approaches. The data collection technique used is the non-participant observation technique by reviewing and examining various research results related to AR-based learning media and the concept of chemical representation. The results of the study with the context of literature studies showed that AR-based learning media (teaching materials) with the concept of representation could increase the reasoning power and understanding of students in learning chemistry. The impact students can interpret more deeply so that their mental models can be reconstructed into scientific concepts. The conclusion that can be taken was that learning chemistry with the idea of representation through teaching materials based on Augmented Reality (AR) could be used as the primary reference in learning chemistry. Besides, the concept also changes the mindset and mental attitude of students as the generation of the Indonesian Nation, where improvements in mood and mentality from an early age have the potential to foster the readiness and resistance of students. That is, the application of this idea shows that natural science (chemistry) has a very vital role in the progress of the Nation, especially towards high-quality education according to the SDGs indicators.

Studi kajian IPA terpadu meliputi bidang kajian energi dan perubahannya, bumi antariksa, makhluk hidup dan proses kehidupan, dan materi dan sifatnya yang sebenarnya sangat berperan dalam membantu siswa untuk memahami fenomena alam secara kontekstual. IPA sebagai pembelajaran terpadu mecoba memadukan beberapa pokok bahasan atau bidang kajian Pembelajaran terpadu merupakan proses pembelajaran yang melibatkan/mengkaitkan berbagai bidang ilmu. Metode penelitian ini menggunakan library reseach. Pembelajaran IPA terpadu dapat dilaksanakan dengan mengorganisasikan dan mengkaitkan dengan berbagai tema atau bidang studi dan keterampilan dalam IPA. Pembelajaran IPA dikatakan terpadu apabila dalam pembelajaran terdapat bagian yang diintegrasikan/dipadukan dalam tema yang kontekstual, beberapa penelitian menggunakan modul pembelajaran dalam mengembangkan pembelajaran IPA terpadu berorentasi kontekstual seperti tema pemanasan global, pemanfaatan tekanan dalam kehidupan dan bunyi. Pembelajaran IPA terpadu merupakan suatu pendekatan pembelajaran IPA yang menghubungkan atau menyatupadukan berbagai bidang kajian IPA menjadi satu kesatuan bahasan. Pembelajaran IPA terpadu juga harus mencakup dimensi sikap, proses, produk, aplikasi, dan kreativitas. Peserta didik diharapkan mempunyai pengetahuan IPA holistik untuk menghadapi permasalahan kehidupan sehari-hari secara kontekstual melalui pembelajaran IPA terpadu.
