The purpose of this study was to make comics as a learning media which could emerge student’s interest in reading, especially for physics lesson and as a means of literacy. The method used was ADDIE (Analyze, Design, Development, Implement, and Evaluation). The phase of Analyze included the determination of the test subject, the software to be used, and the material reference. The stage of Design included the creation of scripts, test concepts, and form indicators. The development stage consists of making comics, testing media experts and concepts, and also doing repairs and printing. The phase of implementation consists of testing on test subjects, specifically 23 Junior High School students. The implementation of comic testing for Junior High School students used observation sheets of the data collection instruments filled by the observers; meanwhile, the test questions and questionnaires filled by the students. In the phase of Evaluation, the data obtained processed qualitatively and quantitatively. Through the tests given after the learning process, it found that 86.9% of the test subjects got a score of 75. There revealed that the comic titled RAINBOW succeeded in explaining the concept of the rainbow process. The results of the questionnaire found that 89.08% of all aspects of the comics' physical form were good and deserved to used as a learning media. Besides, the comic itself could be a means of literacy, and also the students became interested in learning physic. The results of assessment and observations by observers during the teaching and learning activities also stated that the students.

Generally, the learning about projectile motion on inclined surface neglecting air friction can not be delivered during the meeting hours because of the limited time. One way that can be done is by doing independent learning about projectile motion on inclined surface neglecting air friction which is assisted by an independent learning module. The purpose of this study is to design an independent learning module of projectile motion on inclined surface neglecting air friction and to investigate the effectiveness of the module toward undergraduate students’ understanding. Hopefully, this module can enrich the mechanic's modules for the undergraduate students and support them in learning about projectile motion on the inclined surface out of the meeting hours so that they can learn about the projectile motion comprehensively. The method of this study is the ADDIE model of development method consisting of Analysis, Design, Development, Implementation, and Evaluation steps. This independent learning module is applied to three freshmen of the Physics and Physics Education Department. Based on the observation sheet, the undergraduate students were able to do 88% of the module correctly, they also give 90% positive response to the statements of the module, and gets an average evaluation score of 75. Therefore, this independent learning module about projectile motion on inclined surface neglecting air friction is effective in assisting undergraduate students to understand the projectile motion on inclined surface neglecting air friction material.

Research on the development of physics-based dictates based on Problem Based Learning has been carried out to determine the feasibility of the developed physics dictates, students 'responses to the developed physics dictates, and increasing students' critical thinking. The type of research used is a development that refers to the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The subjects of this study were the students of class XI MIPA 2 of SMA Negeri 11 Purworejo, totaling 30 students. The material developed is Dynamic Fluid. Data collection techniques This study was conducted using interviews, observation, questionnaires, tests, and documentation. The data obtained in the form of qualitative and quantitative data, while the data analysis using the Percentage Agreement. Based on the results of the study, the average score obtained from expert lecturers was 3.47, and physics teachers were 3.27 with "quite good" interpretation. The average of the learning outcomes of the two 99% observers with "very good" interpretation. Achievement of learning outcomes obtained an average of 88.62 for the post-test has reached KKM (76). Student responses to the product by 79% with the interpretation "pretty good". The improvement of students' critical thinking skills using the Problem Based Learning textbooks is very high, this is indicated by the magnitude of the normal gain of 0.845. Thus the physics textbook of XI MIPA High School-based Problem Based Learning can be used as an alternative physics teaching material on the subject of Dynamic Fluid.

Kajian Proporsi Aktivitas Fisik dan Kognitif pada Pembelajaran Aktif Fisika: Model Pembelajaran Two Stay Two Stray Diah Aprilia; Wahyu Hari Kristiyanto; Debora Natalia Sudjito

TSTS (Two Stay Two Stray) is one of the learning models often used by educators to make students were doing active learning activities. Still, the educators usually did not pay attention to the lack of that learning model. Some cases found that learning objectives that should have been stressed on the cognitive activities were not achieved because the physical activities are more dominant than cognitive activities during the learning process. This study aimed to investigate whether lesson plans and video of TSTS cooperative learning more emphasized cognitive or physical activities by examining the compatibility between investigated cognitive and physical activities toward the learning objectives of science. There is qualitative research that is analyzed descriptively using the lesson plan sample and video of physics learning applying TSTS. The data analysis of this study was performed by examining a table that contains the possibility of the students’ activities for the lesson plan and students’ activities. That was observed using video during the learning process than were grouped in the physical or cognitive activities based on the operational verb of Bloom Taxonomy. The result of the study is both the lesson plan and video show that cognitive operations are more dominant than physical activities. It means that those activities are following the purpose of science learning. The average of cognitive activities is 77,4%, and physical activities are 22,6%. The educators are suggested to attend the proportion of physical and cognitive activities so that the purpose of science learning can be achieved optimally.

Research has been carried out on the development of teaching aid for measuring water debit using an Arduino based flow sensor as a medium of fluid learning in order to determine the feasibility of a water discharge measuring instrument developed as a fluid learning media. This research is development research consisting of the stages of data collection, product design, design validity, design revision, limited trials. The research subjects for the limited trial were the 4th-semester students of the Physics Education Study Program, Muhammadiyah University Purworejo with 19 students. The product developed is a water discharge measuring device that uses an Arduino-based flow sensor as a fluid learning media through the validation stage by experts. Furthermore, the product is revised and limited to trial. From the results of the trial of the tool carried out the Water Discharge Gauge using an Arduino-based Flow Sensor obtained a debit of (3.80 ± 0.13) liters/minute. While the data from the test results taken manually were debit at (3.55 ± 0.31) liters/min. With a relative error that is very small, with a comparison of sensor and manual measurement data on water discharge of 3.40%. This shows the value of the measurement accuracy is very good. From the results of the validation carried out by the validator namely expert lecturers and peers, it was found that the quality of the teaching aids was included in the excellent category with an average percentage of 76% and the quality of the guidebook was included in the excellent category with an average percentage gain of 78%. A limited trial was conducted by conducting a practicum using a water discharge measuring instrument using an Arduino-based flow sensor, then the results of the student questionnaire responses resulted in a percentage value of 87.22% with very good criteria. Thus the Water Discharge Measuring Tool using Arduino Based Flow Sensors is feasible to be used in Fluid material experiments.
