PENGEMBANGAN PETUNJUK PRAKTIKUM TITRASI ASAM BASA BERBASIS GREEN CHEMISTRY DENGAN INDIKATOR ALAMI DI SMA NEGERI 1 MADANG SUKU III
Abstract: This study aims to produce valid, practical and effective practical instructions for acid-base titration. The development model used is the ADDIE development model modified with Tessmer formative evaluation. The data analysis technique used in the validation is the V Aiken`s formula, in practice it is the Cohhen Kappa formula and the effectiveness uses the Sriwijaya University value conversion and the N-gain test. The results showed that the practicum instructions developed were as follows: 1) Valid, with an average validity score of 0.73 with a very valid category. 2) Practical, obtained with an average practical score of 0.92 for the one-to-one stage (very feasible) and small group evaluation with an average practicality score of 0.90 (very feasible). 3) Effective in improving the performance of students’ psychomotor aspects with an average score of class XI IPA 1 of 85.99 (good) compared to class XI IPA 2 and effective in improving student learning outcomes with a percent N-gain value of class XI IPA 1 (with practicum instructions) is 89.90% compared to class XI IPA 2 (without practicum instructions) which is 58.39%. Based on these data, it shows that the green chemistry-based acid-base titration practical instructions with natural indicators that have been developed meet the valid, practical and effective criteria. Keywords: Development research, practical instructions, acid-base titration, green chemistry, validity, practicality, effectiveness.
