POTENTIAL DRIVER FOR ACCELERATING ADIABATIC DYNAMICS IN COMPLEX WAVE FUNCTIONS
This research is a theoretical study that investigates the literature reviewing the adiabatic acceleration methods of quantum particle dynamics through the application of the fast forward method. This method was initially developed by Masuda and Nakamura in 2010. In this approach, the acceleration scheme is generated through the modification of the Hamiltonian by including regularization terms in the original Hamiltonian. In this study, the fast forward method is applied to a harmonic oscillator system. The fast forward method is first employed to obtain the adiabatic phase. In the subsequent step, through a review of the system's states, a driving potential is identified that ensures the harmonic oscillator system can transition from the initial state to the final state in a short period of time while preserving the system's energy. This research employs adiabatic parameters that are of a general nature, allowing for the use of freely selectable parameters.

DEVELOPMENT OF E-MODULE SCIENCE LEARNING BASED ON PROJECT BASED LEARNING TO IMPROVE CRITICAL THINKING SKILLS
Critical thinking is one of the skills students must possess in the 2013 curriculum, especially in 21st-century learning. Indonesia's low ranking in PISA results in the critical thinking category, ranked 64 out of 65 countries is important from this study. The low thinking skills of students are caused by students' critical thinking skills in science learning are still not optimal. Based on observations made by researchers in the learning process, teaching materials use more books so that learning does not run interactively. This leads to students' critical thinking skills being poorly trained. This research aims to develop teaching materials in the form of project-based learning emodules that improve the critical thinking skills of grade 5 elementary school students effectively. The development method in this study uses a 4-D model from Thiagarajan (1974), namely Define, Design, Development, and Dessimination. The instruments used in this study were interviews, questionnaires, and observations. The results of this study showed that the project-based learning e-module was valid with material validation results of 75.6%, media validation results of 84.5%, and language validation results of 81.25%. In addition, student responses from individual trials were 97%, in small group trials by 90%, and in large group trials by 87%. Quantitative analysis with independent sample t-test using SPSS 26 for Windows showed that there was an average difference in final observation results between the experimental class and the control class of 2.625 with a sig (2tailed) p-value of 0.000. These results were obtained from the responses of experimental and control class students. Thus it can be concluded that the use of e-modules in learning has improved students' critical thinking.
DETECTION TOOL FOR BORAX CONTENT IN MEATBALL FOOD
The use of prohibited food additives is still often found and is even increasing, especially among food entrepreneurs. Small industries or households generally produce these additives. One type of food preservation that is currently widely used is borax and formalin. This research aims to determine the tool's characteristics for detecting preservatives (borax) in food and the presence/absence of preservatives (borax) in meatball food. The method used in this research is an experiment using Arduino, TCS320 colour sensor, LCD, and mini projectboard. The results obtained in this research can conclude that borax is still used in meatball-type food. However, whether the seller uses borax on purpose or the flour used contains borax without the seller knowing it has yet to be known. The borax content itself dramatically influences the frequency value. Based on the results of checks using tools that have been made, meatballs in Wonosobo that are sold to the public have been detected to contain 15% borax. This amount shows a high value and is dangerous for the health of those who consume this food. This research is significant for people who consume meatballs.

STUDY OF THE CONCEPT OF MOVEMENT DYNAMICS BASED ON ETHNOPHYSICS IN THE TANGGAI DANCE
Culture in Indonesia is known to be very diverse, which has not been explored to its full potential due to limited access and minimal awareness of resources in preserving it. Physics learning is often still teacher centered with students becoming uncertain and feeling bored because they think this learning is only based on formulas. So local wisdom is needed with physics learning to implement the concept of movement dynamics with an ethnophysical approach by involving phenomena in students' daily lives to more easily understand learning. Regional dances are one of the local wisdoms that have direct contact with students at school, one of which is the Palembang regional dance, namely the Tanggai dance. This research aims to identify studies of the concept of movement dynamics in movements in the Tanggai Palembang dance. This type of research uses descriptive qualitative with a documentation study approach and the object of this research is the Tanggai dance. Data was collected using two methods, namely the training video analysis method and literature study and the observation method. The results of the research were a study of the concept of movement dynamics in each movement of the Tanggai Palembang dance, especially on the material of Newton's law when changing positions in each movement, moments of force and circular motion in rotating hand swings, conditions for equilibrium of rigid bodies, frictional forces on the legs when walking, and changes in points dancer weight. The ethnophysical approach has the potential to be an innovation in physics learning because it is able to train students scientific literacy to think critically through culture that is integrated into knowledge.
THE EFFECT OF COOPERATIVE LEARNING MODEL THINK PAIR SHARE TYPE ON INTEGRATED SCIENCE LEARNING OUTCOMES CHARACTER
This study describes the effect resulting from using cooperative learning model think pair share type of learning outcomes Science Class V integrated by the character. The purpose of this study was to determine the influence on the learning outcomes of Science Class V students caused by the use of cooperative learning model type think pair share. This type of research is a True experiment with Pretest-Postest Control Design. The population in this study are students which consists of 3 classes, namely VA, VB, and VC classes. Sampling technique in this study using Probabilty Sampling technique with Simple Random Sampling technique. After random shuffle obtained samples of 2 classes, namely the control class consists of 30 students, and experimental class consists of 29 students. This research activity by providing experimental treatment to the experimental class, while the control class was not given treatment. This study obtained the results of pretest and postest testing of students. Each obtained the pretest results of the control class is = 50.1 while the experimental class is = 49.78. After the experimental class was given treatment with think pair share type learning model and the control class was not given treatment, then the postest results of the control class were = 56.23 while the experimental class was = 79.37. Based on the results of hypothesis testing with t-test using SPSS 22.0 program obtained the results of GIS (2-tailed) is 0.000. Referring to the result Sig (2-tailed) value 0.000 < 0.05 then Ho rejected and Ha accepted. This means that in this study there is a significant difference between the learning outcomes of experimental class students and control class students
IMPLEMENTATION OF THE TEAMS GAMES TOURNAMENT TYPE COOPERATIVE LEARNING MODEL ASSISTED WITH QUIZWHIZZER TO IMPROVE STUDENTS' COGNITIVE LEARNING OUTCOMES
Student learning outcomes are still relatively low because the learning model applied in schools is still focused on teacher explanations. Therefore, researchers conducted research by applying a learning model that focuses on students, namely the Teams Games Tournament (TGT) learning model. This research aims to describe the cognitive learning outcomes of MTsS Miftahul Ulum eighth-grade students after the use of a TGT-type cooperative learning technique on the foundational aviation curriculum using Quizwhizzer. This kind of research employs a quasi-experiment with a posttest-only control design. Twenty multiple-choice questions from a posttest served as the data gathering tool. Both descriptive and inferential analysis were used to examine the data. The descriptive analysis's findings demonstrate that pupils in VIII 3 have superior cognitive learning outcomes than those in VIII 1. This is evident from the fact that the control class's average score is 70.31 and the class VIII 3 students' average score is 80.47. The independent sample t-test has a significance value of 0.000, or less than 0.05, according to the inferential analysis findings. Thus, based on the findings of these two analyses, it can be said that students in classes VIII 3 and VIII 1 and VIII 3 who performed better after applying the Teams Games Tournament learning model to basic airplane material had very different cognitive learning outcomes.
VALIDITY OF SUPPLEMENTARY TEACHING MATERIALS ON BUFFER SOLUTION TO TRAIN ARGUMENTATION
Supplementary teaching materials are tools used as an addition to learning. Good teaching materials must pass through a feasibility assessment, such as validity. Validity is important to review the quality and content of teaching materials, by measuring the suitability between aspects of teaching materials. The research purpose is to determine the validity of supplementary teaching materials on buffer solutions that can train argumentation skills. This research is a type of development research that focuses on developing products for learning using the ADDIE model that is limited to the development stage. The instrument used in this research is a validation sheet consisting of content and construct validity. The target of the research is supplementary teaching materials in practicing argumentation skills on buffer solutions. The teaching materials were assessed by 3 validators, that is, experts in chemistry learning. The assessment results from the validation sheet are content validity has a mode of 4 and construct validity has a mode of 4 is declared valid. From this assessment can conclude that the supplementary teaching material on buffer solutions material is valid in supporting argumentation skills training. Based on the results, it is expected to contribute to producing additional teaching materials that are feasible to help train the argumentation skills of students. In addition, the results of this study are also expected to help readers, especially educators, to gain knowledge and references to teaching materials that can be used in training argumentation skills.
