Developing Student Worksheets (LKPD) based on Problem Based Instruction on Environmental Pollution Material

Abstract

This study aims to reveal (1) how the characteristics of LKPD based on Problem Based Instruction models on environmental pollution material (2) how the feasibility of LKPD based on Problem Based Instruction models on environmental pollution material (3) how practicality of LKPD based on Problem Based Instruction models on environmental pollution material. Research refers to the Borg and Gall development model to the seventh stage, namely potential and problems, data collection, product design, design validation, design revision, product testing, product revision. The research instruments used in data collection were interviews, observation, and questionnaires. The data obtained were then analyzed by quantitative descriptive analysis. The characteristics of LKPD teaching materials developed using the Problem Based Instruction model on environmental pollution materials are arranged systematically, interestingly, and clearly. Students can learn independently; the developed LKPD does not depend on other media, and students can interact directly with the environment. Based on the feasibility trial LKPD is in the "Very feasible" category. Material experts with grades X≥ 33 categories are very feasible, media experts X≥ 45 categories are very feasible, linguists X≥ 18 categories are very feasible, expert practitioners X≥ 42 categories are very feasible, and students' responses X≥ 33 categories are efficient. The results obtained can be concluded that the developed LKPD meets the very feasible category, so it is suitable for use.
