INTRODUCTION Curriculum Practical activities in physics subjects are learning activities that examine natural events that occur systematically and purposefully . In one of the physics learning materials, namely the theoretical concept of Archimedes' Law in Static Fluid material, this is material that in the learning process requires a specific realization picture to facilitate understanding of the material concept. The picture of this realization can be visualized with practical activities. Archimedes' Law Practicum aims to determine the magnitude of the upward pressure or upward force received by an object and to find out what factors influence the magnitude of the upward force. JIPF. Vol. 10 No. May 2025 Practical activities cannot be separated from the teaching aids used to visualize and realize theoretical concepts in learning material. Visual aids are all kinds of tools used as learning aids to demonstrate and visualize learning material . Using teaching aids will help students understand the learning material presented. The subject of Archimedes' Law in Static Fluid material is material that needs to be presented clearly and in detail so that teaching aids are needed as learning media so that the material can be well received by students . Progress in Science and Technology is one of the factors that supports renewal in various fields. Technology that continues to develop is very helpful in the process of improving learning, especially in the use of modern technology-based learning media . Learning media is a set of tools or complements in a learning activity that are used by educators in order to improve communication between educators and students . Learning material delivered using learning media will be clearer, more complete and more interesting. Learning media is also able to present material that can arouse curiosity, stimulate students to react physically and emotionally so that learning activities can be carried out effectively. Learning media needs to be adapted to modern technological developments to support learning activities. So teaching aids are needed that are integrated with emerging technological advances which refer to Minister of Education and Culture Regulation No. 65 of 2013 which states that the learning process in educational units must be carried out in an interactive, inspiring, fun, challenging manner, motivate students to participate actively, and provide sufficient space for initiative, creativity. Based on the results of interviews conducted by researchers with the Head of the Laboratory and students of the Physics Education Study Program. Muhammadiyah University. Purworejo, information was obtained that lecture activities, especially in the Basic Physics Practicum I course in the Archimedes Law practicum, still use conventional practicum tools so that it still makes it difficult for students to understand and still requires practicum time. relatively long. The lack of proper digital physics teaching aids in the laboratory is also still an obstacle to supporting effective learning which causes students to still have difficulty understanding the concepts of physics material well. So we need facilities to support interesting and efficient learning activities to increase students' understanding, especially on the subject of Archimedes' Law. One of the means that can support learning activities is using teaching aids that are based on modern technology and are digital. This problem is similar to the results of research conducted by Pratiwi & Linuwih . which states that the use of Archimedes' Law teaching aids as a medium for learning the subject of Archimedes' Law in Static Fluid material is good by utilizing a variety of objects used as practical objects so that the influence of objects on the magnitude of the upward force can be known. However, it is less effective in collecting data which is still done manually so it takes a relatively long time. Research that supports this problem was also carried out by Palupi . which states that teaching aids with traditional components and used manually are prone to data collection errors and the data obtained tends to take time because of the many processes that must be passed. Teaching aids can be developed innovatively and creatively in line with current technological advances and in accordance with learning objectives. Based on this description, one of the main materials in physics learning that requires new innovations in the learning process is Archimedes' law. Archimedes' Law requires clear and attractive visualization to make it easier for students to understand learning material and improve students' psychomotor Referring to the development of the times which demands all aspects of life, including in the field of education, demands to create new innovations in learning activities, especially new breakthroughs in creating learning media, especially in practical learning in the form of teaching aids by utilizing technological advances to improve the quality of learning. Based on the explanation of the problem, in general laboratory room facilities are available, but the practicum activities carried out have not been effective due to the lack of digital teaching aids, so the p-ISSN: 2477-5959 | e-ISSN: 2477-8451 Archiduino as a Media for Learning Physics: A Laboratory Study Wakhid Akhdinirwanto. Abi Diana. Yusro Al Hakim. Eko Setyadi Kurniawan researcher designed an Arduino-based Archimedes' Law teaching aid (Archiduin. as a physics learning medium. METHOD The method used in this design research modifies the ADDIE development model which consists of Analyze. Design. Development. Experimentation, and Evaluation. The first stage of designing Archimedes' Law teaching aids is an analysis of the needs for teaching aids which aims to find out what is needed in designing an Arduino-based Archimedes' Law teaching aid. The things needed in designing an Arduino-based Archimedes' Law teaching aid are materials, as well as the tools and materials that will be used. Apart from that, the need for Archimedes' Law teaching aids in the laboratory was the fundamental reason for carrying out this research. The second stage, namely material analysis, is carried out by identifying the material that will be taught using demonstration tools and based on literacy results through several studies of research Analysis was also carried out using various references as considerations for researchers to determine the tools and materials that will be used in designing Arduino-based Archimedes' Law teaching aids. The design stage is a stage that aims to design the tool. At this stage the final result will be obtained which is called Prototype I. The design of the props created can function well in determining quantities in Archimedes' Law material. The Arduino programming process starts from reading the water level before and after the load is applied. then using the Fa button the V variable data is calculated into a Fa value . pward forc. by multiplying the V value by the density of water (A) and gravitational acceleration . The results of the upward force measurement are then called up to be displayed on the LCD with a data accuracy level of two numbers behind. In order to test the function of the teaching aids, trials are carried out in the laboratory by testing the sensors and system 10 times to obtain data and calculate the uncertainty value from the test data. Based on the data from the test results, the accuracy and precision of the teaching aids that have been designed can be determined. This stage aims to produce a revised Prototype II. The next stage, in order to determine the usefulness and readability of the tool, is validated by a media expert validator and a material expert validator. The results of this test will provide an average value which will later become a reference for whether the teaching aids can be said to be appropriate or not. Expert validation results do not only contain assessments but also criticism and suggestions. This revision stage aims to revise the results of Prototype II in accordance with the criticism and suggestions provided by the validator. Based on the validity category of a media, the validation test data is then analyzed based on the Aiken index validation data calculation guidelines . These references can be seen in Table 1. Table 1. Props evaluation criteria Score Intervals Category V > 0. Tall Currently 40 V 0. V < 0. Low Based on the data from the validation test results, it can be seen whether the teaching aids that have been designed meet the validity values. At this stage a product is produced which is referred to as Prototype i. The next stage is a practical test by involving students in using the teaching aids. This stage was carried out after Prototype i obtained valid criteria from the validation test . The sample that the researcher will use is 10 physics education students at Muhammadiyah University. Purworejo, using a student questionnaire. During the practicality test, the aspects measured include benefits, presentation DOI: 10. 26737/jipf. JIPF. Vol. 10 No. May 2025 and physical appearance. The data from these tests is then analyzed to identify potential problems, limitations, or deficiencies that might affect the performance of the tool in a real environment. These references can be seen in Table 2 . Table 2. Criteria for Student Response Data Analysis Score Interval (%) Category Very good Good Enough Not enough Very less Based on the results of this analysis, it can be seen whether the teaching aids that have been designed meet practical values. The final stage is an evaluation carried out by assessing the quality of the product according to the results of laboratory tests, validation tests and practicality tests that the researchers have carried out. Research subject The subject used in this research is an Arduino-based Archimedes' Law teaching aid which is then called Archiduino Research Instrument Instruments are tools used by researchers to collect information and data in a study . The instruments used in this research include . Observation sheets which have been prepared according to the assessment rubric developed and then given to physics education students at Muhammadiyah University. Purworejo. This observation was carried out to obtain information regarding teaching aids and find problems in the physics learning process in accordance with the objectives of the research. The validation sheet in this research consists of media and material expert validation instruments which aim to validate the product and determine the suitability of the teaching aids being developed. Validation is carried out to determine the validity of the teaching aids designed before implementation. The validation results are also used as a basis for making improvements to the designed tool. The assessment is carried out by giving a range of 4 values, namely: . very good. less good. not good. The product validation grid for Archiduino and the teaching aid manual can be seen in Table 1 for validation from media experts.

RESULTS AND DISCUSSIONS Archiduino design research will be realized in February Ae August 2023 at the Integrated Physics Education Laboratory. The following stages of props design are carried out: Analyze At this stage, the first step taken was an initial analysis carried out on the head of the physics education laboratory and students at Muhammadiyah University. Purworejo. The results showed that there were no Arduino-based Archimedes' law practicum tools available, there was still a lack of digital teaching aids in the laboratory, and learning activities carried out in the classroom. So far, classical methods have been used in the form of material explanations and classroom demonstrations using conventional . teaching aids. Analysis of the objectives and material used, namely Static Fluid material on the subject of Archimedes' Law. Archimedes' law states: "The upward force on an object immersed in a fluid is equal to the weight of the fluid displaced by that object. "This means that the fluid transferred refers to p-ISSN: 2477-5959 | e-ISSN: 2477-8451 Archiduino as a Media for Learning Physics: A Laboratory Study Wakhid Akhdinirwanto. Abi Diana. Yusro Al Hakim. Eko Setyadi Kurniawan the volume of fluid which is the same as the volume of the part of the object that enters the fluid. If an object is dipped into a container that is initially completely filled with water, the water that spills from the container is the volume of water displaced by the object . Mathematically. Archimedes' Law can be written in equation 1. Information : Fa = Archimedes force (N) A = Density of liquid . g/m. g = Gravitational acceleration . /s. V = Volume of submerged object . The aim of the Archiduino designed is to find the value of the upward force received by an object inserted into a fluid. It is hoped that the output results from this Archimedes' Law teaching aid can provide an understanding of the theoretical concept of Archimedes' Law.

Limited Test This stage aims to determine the level of practicality of the teaching aids. The trial was carried out on 10 Physics Education students at Muhammadiyah University. Purworejo. The trial was carried out with practical learning where after the learning was completed, students were asked to fill out a response questionnaire. The practicum is carried out in accordance with the practicum guide that has DOI: 10. 26737/jipf. JIPF. Vol. 10 No. May 2025 been created. Practical learning is carried out in 3 meetings. Where each meeting discusses different At the first meeting, the material discussed was related to the concept of floating objects in Archimedes' Law. Practical learning at the first meeting went well, but there was an obstacle, namely that students were not able to understand the concept of the material to be implemented. The solution to this obstacle is for the researcher to provide a more detailed explanation regarding the material that is the practical topic. At the second meeting, the material discussed was the concept of floating objects in Archimedes' Law. Practical learning of course begins with an opening stage in the form of greetings and checking Learning is progressing as it should, but there are obstacles, namely students still don't understand how to use teaching aids, so practical learning takes a long time. As a solution to these obstacles, researchers provided more detailed explanations to students regarding the use of teaching In the third meeting, the material discussed was the concept of sinking objects in Archimedes' Law. The practicum implementation begins with an opening stage in the form of greetings, checking attendance, and apperception. At the core stage, the researcher explains in detail the parts of the props and how to use them. Then the researcher guided the students to carry out experiments on Archimedes' law using the teaching aids that had been made. In the closing stage, researchers and students together process the practicum data and conclude it. Practical learning was carried out well. However, there is an obstacle in the form of students not being able to connect the results of Archimedes' law practicum with the application of Archimedes' law in everyday life. The solution to this problem is that researchers provide examples related to the application of Archimedes' law in everyday life that can be put into practice. At the end of the activity, students were asked to fill out a response questionnaire to the teaching aids. The results of student responses are presented in Table 7. Table 7. Results of student responses to Archiduino Aspect Average Score (%) Category Benefit Very good Presentation Good Physical appearance Good Average Very good Based on student responses presented in table 13, the average score was 3. 83 with a percentage of 83% in the benefits aspect, the average score was 3. 35 with a percentage of 83. 75% in the presentation aspect, the average score was 3. 24 with a percentage of 81. 00 % on the physical appearance aspect. From all aspects, an average score of 3. 47 was obtained with a percentage of 86% and it can be concluded that the Archimedes' Law teaching aids are in the very good category. Implementation This stage aims to determine the working function of the teaching aids as practical teaching aids for Archimedes' Law. The trial was carried out to prove that the designed teaching aids could be used to measure the Fa value on the subject of Archimedes' Law by comparing the Fa value obtained from the teaching aids with the theoretical Fa value. (Masyruhan et al. , 2. This test was carried out using three variations of objects as experimental objects, namely objects with Vb = 0. 000090 m3. Vb = 000150 m3, and Vb = 0. 000283 m3 to measure the upward pressure force (F. on each object.

Yusro Al Hakim. Eko Setyadi Kurniawan Theo Props Fig 5. Graph of the relationship between Archiduino Fa values and theoretical Fa values Based on a comparison between the Fa value using props and theoretical calculations, the results obtained were that in the experiment using a variation in the volume of the object of 0. 00009 m3, the results of the experiment using props obtained an average Fa value of 0. 89 N, while in theory the average Fa value was 0. 88 N. In the experiment using variations in object volume of 0. 00015 m3, the results of experiments using visual aids obtained an average value of Fa of 1. 48 N, whereas in theory the results obtained an average value of Fa of 1. 47 N. In the experiment using variations in object volume of 0. 000283 m3, the results of experiments using teaching aids obtained an average Fa value 77 N, while in theory the Fa value was 2. 77 N. Based on the comparison made between the Fa value when using the props and theoretical calculations, it can be concluded that the results of the props measurements are close to the theoretical results within the limits of error. Evaluation The evaluation stage carried out analysis of the results of the laboratory trial stages, validity tests and limited trials of Archiduino. The validity of Archiduino is known through the results of the validation test recapitulation, namely obtaining an average percentage of media expert assessments of 88. 02% in the valid category and media experts 87. 96% in the valid category. The results of the limited trial were that the average percentage was 86. 86% in the good category. The next evaluation will focus on improving the teaching aids and the accompanying guidebook. Some suggested improvements include adding a waterpass to indicate the level of inclination of the Additionally, the researcher will add a cover that can be opened and closed during experiments to reduce the influence of wind. The guidebook table will also be revised and adjusted to align with the Archimedes' Law practical activities. Furthermore, the guidebook will include illustrations that demonstrate Archimedes' Law and explain the variables in the equation. CONCLUSION Archiduino, which was designed to meet the valid criteria based on the results of the assessment by media experts, obtained an average percentage of 88. 31% in the valid category and the results of the assessment by material experts obtained an average percentage of 87. 96% in the valid category. Archiduino met the practical criteria in a limited trial of 10 students, and received student responses to the teaching aids in the aspects of benefits, presentation of the tools and physical appearance with an average percentage of 86. 86% in the very good category. Thus Archiduino is valid and practical so it can be used as an alternative teaching aid in learning DOI: 10. 26737/jipf. JIPF.
