The study aims to analyze students' misconceptions using a three-tier diagnostic test on acid-base material. The type of research used in this study is descriptive research. This research was conducted at SMAN 1 Mamuju to grade XI MIPA students. Data collection techniques employed diagnostic test in the form of multiple-choice stratified. The first level contained the students' answers, the second level was the reason for the answers, and the last level was the level of confidence. Data analysis was conducted by looking for the percentage of misconceptions from each concept in Acid-Base materials, namely the concept of acid-base theory, pH indicators of acid-base solutions, strength of acids and bases, and calculation of pH of acid and base solutions. The results show that the category of students' misconceptions on acid-base materials using the three-tier diagnostic test instrument is the M1 category. In this category, students answered incorrectly at the first and second levels but were sure that the answers at both levels were correct. The percentage obtained in the M1 category is 33.87% with moderate category. Students' misconceptions occur in the concept of acid-base theory according to Bronsted Lowry with a percentage of 70.33% in item 4 and 73.08% in item 18. The concept of pH indicator of acid-base solutions with a percentage of 73.08% in item number 9 while for the concept of the strength of acids and bases with a percentage of 76.36% in item 9. For the concept of calculating the pH of an acid-base solutions, 3 items are obtained that fall into the category of high misconceptions, namely item 14 with a percentage of 83.52%; item 16 with a percentage of 82.42%; and 20 items with a percentage of 78.02%. The causes of misconceptions in students are due to the incomplete reasoning, students' abilities, students' interest in learning, and teacher’s teaching methods.

This research is a development research that aims to develop RatuChemWeb in the Flipped Classroom learning model to increase students' motivation and learning outcomes on Acid and Base subject which is valid, practical, and effective to be used. The development model used in this study referred to Addie development model, which consisted of several stages, namely analysis, design, development, implementation, and evaluation. RatuChemWeb media that had been developed was conducted the validation stage by the validators/experts and had gone through trials and had been revised by developers to produce learning media which were valid, practical, and effective. The results show that the development of RatuChemWeb media have: (1) the media expert’s validation by 3.96 which is very valid criteria; (2) the material expert’s validation by 3.68 which is very valid criteria. The RatuChemWeb media is stated as practical due to the practicality test related to (1) its implementation in the Flipped Classroom learning model gains an average value of M = 1.98 with the category of being fully implemented, (2) the teacher's response is very positive with a percentage of 98.92% with very practical criteria, and (3) the students' responses are very positive with a percentage of 84.02% with very practical criteria. The media also meets the effective criteria with the results: (1) based on the Wilcoxon test, it obtains the significance value of p-value smaller than (0.000 < 0.05), which means there is a difference in the average students’ learning motivation before and after learning by using the RatuChemWeb media in the Flipped Classroom learning model with the increase of students' learning motivation from 60.83% to 74.72% and (2) the class completeness is 82% and the average value of N-Gain is 77% which is in high category.

This Study is a development research that aims to produce interactive media based on appypie reality in a valid, practical, annd effective pronlem based learning model. The development model used is the ADDIE development model which consists of five stages, namely the analysis stage, the design stage, the development stage, the implementation stage, and the evaluation stage. The interactive media based on appypie that was developed was validated by two experts. Then, it was tested to 29 students in grade XI MIA 3 SMAN 3 Pinrang. The analysis used is data analysis of validity, practicality and effectiveness. The interactive media based on appypie is stated to valid based on the result of validating interactive media based on appypie with an average value of the media expert of 3.76, which are in very valid category. The interactive media based on appypie is stated to be practical based on (1) the implementation of interactive media with an average total percentage of 95,60%, which is in very high category; (2) the teacher's response with an average score of 95,75%, which is in very practical category; and (3) the students’ responses with an average score of 88,25%, which is in very practical category. The interactive media is stated to be effective based on the results of the analysis of the learning outcomes test and analysis of learning interest questionnaires with a class completeness percentage of 84% and an average value of the percentage of learning interest assessment of 81%, which is in high category. Therefore, the results of the study indicate that interactive media based on appypie in the proble, based learning learning model has valid, practical, and effective qualities.
