Ethnopedagogy Of Innovative Acid Base Book Based On Problem Based Learning Integrated Dekke Naniura The Local Wisdom Of Batak Toba

Indonesia, particularly North Sumatra Province, is rich in local wisdom, including traditional cuisine, customs and culture, and unique plants, but these have not been widely used to enrich chemistry teaching materials. This study aims to develop an electronic textbook for Acid-Base Chemistry based on Problem-Based Learning, PBL, and integrated learning. Dekke Naniura, a typical Batak Toba dish.
