Data collection was conducted in two ways: observational surveys of students and interviews with teachers. Meanwhile, the instruments used were questionnaire sheets and interviews. Through data collection, it was found that learning based on Problem Based Learning (PBL) had not been implemented and there was no LKPD model of PBL-based learning, especially on biodiversity material. Therefore, it is necessary to develop LKPD based on PBL on biodiversity material for grade X of high school.]]>
