This research aims are to develop a chemistry practicum worksheet by utilizing the environmental potential for distance learning, analyzing the feasibility and evaluates the effectiveness of the worksheets implementation to improve learning achievement of the Senior High School student. Research and Development (R and D) method was applied using 4D (Define Design Develop and Disseminate) design. The data collected using questionnaire, observation, and a cognitive test method. Quantitative analysis method applied through calculating the average score and determining criteria at certain class intervals. The results of the research found that the feasibility of the chemistry practicum worksheets has been examined and gets percentage scores of 82.82% and 89.07%, that means reach in the very feasible criteria. The chemistry practicum worksheets are stated to be effective because 23 out of 26 examined students got higher scores than the Minimum Completion Criteria. According to the expert's judgment, the part of the worksheets which must be revised and developed is the cognitive level of the questions, the depth of the material, and the consistence of the design. It can be concluded that the chemistry practicum worksheet by utilizing the environmental potential is very feasible and effective to be used as a chemistry practicum learning media for distance learning. © 2023 Author(s).
