Practical learning without limitations of space, time, and place through an e-learning system allows students to learn independently, efficiently, and effectively which also can be applied as a solution to improve students' mastery of Japanese grammar. This research applies the Analysis. Design. Development. Implementation, and Evaluation (ADDIE) model in developing e-learning application designs on smartphones. The data in this study were collected using pre-experimental methods and by distributing Likert scale questionnaires to fifteen students. The application developed is named AuManabu BunpouAy, validated by the IT team, and consists of JLPT level N4 grammar practice tests, several levels, and quizzes. The material including ninety-three Japanese sentence patterns developed from several sources and also contains conversation videos accompanied by texts. From the questionnaires distributed to Japanese language learners, the AuManabu BunpouAy application is considered highly accessible, helps improve understanding of basic Japanese grammar, and supports independent learning. However, according to the participants, the materials in the application are still limited and hence need further development. KEYWORDS ADDIE model. Applications. Japanese Grammar. Manabu Bunpou.

First received: 01 December 2023 ARTICLE INFO Revised: 15 June 2024 Available online: 25 June 2024 INTRODUCTION Japanese is one of the foreign languages studied and popular in Indonesia, based on data from the Japan Foundation in 2012, the number of Japanese language learners in Indonesia reached 872,411 people, in 2017 the Japan Foundation again released a survey of the number of Japanese language learners in 2015, totaling 745,125 people, in 2018 there were 709,479 people and in 2021 there were 711,732 people. This number has increased. Final proof accepted: 20 June 2024 but Indonesia is ranked second worldwide as the most Japanese language learners after China and first in Southeast Asia based on the Survey Report on Japanese Language Education Abroad . However, there are still problems for Japanese language learners in the learning process because Japanese and Indonesian have large differences regarding linguistic elements such as letters, kanji, and Japanese grammatical structures (Bunpo. 51 | P a g e e- ISSN 2528-5548 | p-ISSN 27764478 Herniwati Herniwati. Nuria Haristiani. Melia Dewi Judiasri. Millati Qisti Rabathi. Noa Funaki The Development of AuManabu BunpouAy Smartphone Application for Basic Japanese Grammar Learning Despite this surge in language education, introducing Japanese as a foreign language constitutes difficulties in teaching and learning, as highlighted in a few studies. In a recent review of language training needed by State Department employees. Everson . claims that languages such as Japanese and Chinese take at least four times longer to learn and master than European Racoma . stated several possible factors that may dictate the ease of learning, such as unfamiliar accents, morphology, and a huge deviation of the writing system from the Roman alphabet in some natives (Everson, 2011. Racoma. Quintos, 2. In the Japanese Language Proficiency Test (JLPT), many students find it difficult to learn Japanese at each level, especially in vocabulary (Moji Go. , grammar (Bunpo. , reading (Dokka. , and listening (Chouka. The research was conducted to improve and solve problems related to Japanese language education and teaching, including how students can pass the Japanese Language Proficiency Test (JLPT) starting from levels N5. N4. N3. N2, and N1 because it is one of the requirements for graduating from higher education is to graduate from JLPT N3 and the requirement for prospective workers to Japan who study at educational institutions is to graduate from JLPT N4. One solution to solve the above is to create an application via smartphone called AuManabu BunpouAy aimed at Japanese language learners in understanding Japanese grammatical structures (Bunpo. JLPT level N4 as an easy and fun interactive media. Every year the Japanese government holds the Japanese Language Skill Test (JLPT) carried out worldwide, including in Indonesia. This test has been the Japanese language competency certification standard for foreigners worldwide since 1984 as explained on the Jlptonline. id website. The instructors held this test to assess students' ability to understand Japanese, and students can use the test results for study requirements or job Since the first test, 7,000 people from 15 countries participated in it. then in 2011, the number of participants taking the JLPT increased to 610,000 people in 62 countries. In 2018, more than 1,168,000 participants in 86 countries took the JLPT, and in 2023, there were 787,954 exam takers. This test makes the JLPT the largest-scale Japanese language exam in the world (Japan Foundation. The efforts to make it easier for students to understand learning materials must teach materials and Japanese language learning media that can support graduation. Ali . defines learning media as anything that can convey messages and stimulate students' thoughts, feelings, attention, and will to encourage the process. Forms of media are used to enhance the learning experience to make it more concrete. Susilana and Riyana . argue that learning media always consists of hardware and the message elements it carries . essage/softwar. Learning media is a tool that teachers use to support the explanation of learning materials. The role of learning media is critical and has an equal position with the teaching method (Sanchez-Sepulveda. Fonseca. Garcya-Holgado. Garcya-Peyalvo. Franquesa. Redondo, & Moreira, 2. With learning media, the teacher can deliver the teaching material to be more concrete and make students easier to absorb the learning material (Peebles. Bonus, & Mares, 2018. Rachmadtullah. Zulela, & Sumantri, 2. In this technology era, the teacher usually uses multimedia resources such as graphics, videos, and animations can help students better understand and retain information (Kirkorian. Kissi & Dreesmann, 2018. Dewanty. Haristiani. Sadewo, & Tasman, 2. Many learning media in the teaching and learning process, such as smartphones and electronic devices (Bao. Xing. Xia, & Lo, 2019. Rohaeti. Bernard, & Primandhika, 2. Thus, it is very important to note that learning media requires equipment to present messages, but the most important thing is not the equipment, but the message or learning information delivered by the media. Learning media supports diverse human They match established competency standards and learning goals. To support these learners, they need more than one medium. They need to be able to enjoy learning. Many learning media are made using various applications that require teachers to have an understanding and skills in Information and Communication Technology (ICT). By understanding ICT, it can make it easier for teachers to create various media, such as making learning videos from Kinemaster. Filmora, and so on (Ritonga. Ritonga. Tangse. Putri. Ritonga, & Ritonga, 2. It is a human need. It usually looks for objects in the environment to help the senses. occurs with awareness or without awareness. Also, the media plays a big role. It makes learning better and more fun. Multimedia-based learning media is here to solve this problem. Multimedia can touch all five senses, sight, smell, taste, hearing, and touch. 52 | P a g e e- ISSN 2528-5548 | p-ISSN 27764478 JAPANEDU: Jurnal Pendidikan dan Pengajaran Bahasa Jepang Vol. No. June 2024, pp. The Computer Technology Research (CTR) says that people can only remember 20% of what they They can remember 30% of what they hear. But people can remember 50% of what they see and hear and 80% of what they see, hear, and do at once. Besides that, according to Munir . , multimedia can provide benefits in conveying and receiving These include being clearer. It uses images and animations that are easy to understand. It is easy to make changes because the computer stores all information. You can continue to update and develop it. It is also more interactive and frees the developer to apply his creativity to be clear and look good. There has been a lot of research on how to learn Japanese grammar. For example. Judiasri . researched digitalization-based Drill Bunpou to Japanese Sastranegara . researched the role of quiz tests in increasing learner motivation in understanding basic level Japanese grammar, and Herniwati and Fatmariana . developed a smartphone application AuHenka DoAy changes the Japanese verb te. Furthermore. Haristiani. Arifin. Prajayanti. Hasby. Taufik, and Anggarini . Rifai. Haristiani, and Risda . , and Haristiani and Rifai . developed the AuGengobotAy application as a medium for learning Japanese grammar based on the Japanese Language Proficiency Test (JLPT) at the N3 level. As time goes by, fun learning media and methods must still be developed to improve the quality of abilities of Japanese language learners. The explanation above shows an improvement in the multimedia learning process. This media provides rich content that meets a variety of human sensory needs, especially if the media is easily accessible, such as applications on smartphones. Students can use smartphone devices, with various applications in them to support learning activities, wherever they are. The following is a theoretical framework of smartphones for learning in mobile learning (Firmansyah, 2. Conceptualization of mobile learning: The concept of mobile learning is a learning process that is centered on students learning various materials so that they gain experience when they learn through mobile devices. Mobile learning is part of the new conception of Research and reflection on mobile learning interdisciplinary thinking and methods in . Mobile device application for knowledge management: Implementation of mobile applications must be able to create a different learning environment and increase student A teacher must know the experiences of students while learning and find strategies to improve the learning process. Mobile learning can encourage students to acquire, store, share, apply, and create knowledge. Mobile device application for language learning: Language is the main thing in social life because people who are proficient in language will be able to communicate and socialize Smartphones with adequate internet network support can be good language-learning media. Existing learning environment: The current learning environment aims to integrate learning activities on the spot so students can interact appropriately with each other and the environment. Especially if the media is easy to access, such as an application on a smartphone, they prove the technological progress of cellular telephones by not only enabling users to make calls and send messages but also to learn and access a wealth of information. The Ministry of Communication and Information of the Republic of Indonesia stated that smartphone users in Indonesia in 2020 reached 78 million users and 143 million internet users out of Indonesia's 265 million population. This matter makes the prospects for using smartphone-based learning media very good. With the emergence of smartphones, they are active in observing, demonstrating, doing, and so on. Apart from that, smartphones are also very suitable to be used as an online learning medium without having direct faceto-face meetings between educators and students (Nahak, 2. This matter makes smartphones an effective tool to accompany all activities, one of which is learning activities that can make it easier for users, including Japanese language learners. Thus, the AuManabu BunpouAy application can help students master Japanese grammar at JLPT level N4 Smartphones are proof of the technological progress of cellular telephones which can not only be used for making calls and sending messages but can also be used for learning and obtaining wider The Ministry of Communication and Information of the Republic of Indonesia stated that smartphone users in Indonesia in 2020 reached 78 million users, with 143 million internet users out of the 265 million population of Indonesia. This makes the prospects for using smartphone-based learning media very good. This statement is in accordance with Wahid and Cerya . state that good media is media that is easily accessible to students and teachers anywhere and anytime. Such as Android or smartphone technology that is used as a learning media that can provide a learning material 53 | P a g e e- ISSN 2528-5548 | p-ISSN 27764478 Herniwati Herniwati. Nuria Haristiani.

Noa Funaki The Development of AuManabu BunpouAy Smartphone Application for Basic Japanese Grammar Learning application that has efficient and effective impacts that learners can download related to the material required so that it can be repeated anytime and studied independently (Jengathe & Rojatkar, 2015. Arifin. Prajayanti. Hasby. Taufik, & Anggarini. With the emergence of smartphones, students can be active in observing, demonstrating, doing things, and so on. Aside from that, smartphones are also very suitable to be used as an online learning medium without having to have direct face-to-face meetings between teachers and students (Nahak, 2. This makes smartphones an effective tool to accompany all activities, one of which is learning activities which can make it easier for users, including Japanese learners. Thus, it is hoped that the development of the AuManabu BunpouAy application on this smartphone can help students master Japanese grammar at JLPT level N4 better. METHODS This research uses quantitative descriptive research to analyze students' views on the use of the AuManabu BunpouAy smartphone application as an interactive learning media that applies ADDIE (Analysis. Design. Development. Implementation, and Evaluatio. to determine the development of the media used, including its quality and The quality and effectiveness of the media were tested by validation using a Likert scale. The data was tested using an instrument consisting of 15 questions distributed on aspects of learning media, interactive and fun. In every learning media development process, there should be a learning design model which is referred to as a development procedure guide (Segaran et al. , 2. The ADDIE model is one of the most widely used learning design models. ADDIE has five phases in learning design, namely Analysis. Design. Development. Implementation, and Evaluation (Adoobie, 2015. Hess & Greer. Mitsui, 2. In addition. ADDIE is a useful implementing development and learning programs which makes ADDIE have an important enlightening effect on the development of contemporary education (Mayfield, 2. The stages of the ADDIE model can be seen in Figure 1. The implementation of ADDIE in developing the AuManabu BunpouAy application on smartphones is described as follows. Analysis Stage At this stage, the students' Japanese skills and Japanese textbooks are analyzed as well as the JLPT N4 practice questions, especially those in accordance with JLPT N4 which will later be applied to the application. Design Stage At this stage, the developer prepares everything necessary for application development based on data in the previous analysis stage including application flowcharts, application design, and database preparation taken from .

The software used in this development includes Microsoft Office PowerPoint 2019, iSpring Suite 9. Website 2 APK Builder as the application database used, and Sublime text editor for writing the application programming language. Development Stage The AuManabu BunpouAy application on smartphones was developed based on a flowchart that had been created previously. Then the application is tested by experts in their respective fields to find out the drawbacks that can be corrected in the application. strengthen the results of the trial, several experts consisting of media experts and material experts were also involved to provide feedback on the product being developed. Implementation Stage At this stage, the application was tested on 15 Japanese students in the 4th semester to find out students' responses regarding the use of the application developed in learning. Apart from that, there was a team of IT experts who assessed the suitability, advantages, and disadvantages of the AuManabu BunpouAy application being Evaluation Stage The evaluation stage was carried out to determine the advantages and disadvantages of the application developed based on data collected from 15 Japanese students and two people from the team of IT experts, as well as one expert in Japanese language education as a validator through a questionnaire at the implementation stage. The following are the research stages: 54 | P a g e e- ISSN 2528-5548 | p-ISSN 27764478 JAPANEDU: Jurnal Pendidikan dan Pengajaran Bahasa Jepang Vol. No. June 2024, pp. Figure 1: ADDIE model stages . dopted from Tanaka. The smartphone application development includes an explanation of the stages of application creation, application design structure, and development of bunpou N4 material from explanations of sentence patterns to example sentences, conversations equipped with audios, and quizzes on JPLT N4 questions. The instruments used in this research include a Likert scale questionnaire filled in by respondents, namely students and experts. The results of the questionnaire were analyzed using a qualitative approach and then revised according to the results of the existing responses. Apart from that, data results in the form of scores obtained from Likert scale questionnaires can be analyzed using quantitative descriptive analysis in the form of average calculations (Sugiyono, 2. The results of the average calculation are then converted into a percentage to conclude whether the product being developed is suitable for use using the feasibility criteria in Table 1 below. Table 1: Feasibility percentage scale according to Arikunto . Percentage of achievement Interpretation 76 - 100 % Very Feasible 56 - 75 % Feasible 40 - 55 % Fairly Feasible 0 - 39 % Not Feasible FINDINGS AND DISCUSSION Application Analysis Development Data help Japanese learners regarding bunpou material, especially at the JLPT N4 level. This application contains material in the form of conversation videos, conversation texts, and grammar discussions along with example sentences. There are also practice questions that are equipped with the discussion of the answers. There are several stages in creating this application under the ADDIE stages (Segaran. Ali, & Hoe, 2014. Adoobie, 2015. Hess & Greer, 2016. Mitsui, 2. The stages carried out are the same as the stages in developing learning media. Namely the Analysis. Design. Development. Implementation, and Evaluation stages. In the analysis stage, the need for students to create interactive learning media for independent learning bunpou JLPT N4 via smartphone. In the design stage, there are some steps as Create the application concept The design created at the initial stage determines the description of the application that will be created later. At this stage, researchers determine what features the application will have, what the layout is like, what the design structure is going to be, and so on. Prepare the design assets. Design assets that are prepared include images or videos that will be included in the application, color schemes that will be used, and various other things related to making the application look interesting. Prepare supporting programs. In creating this application, there are other supporting programs needed to make the creation process easier and run smoothly. Some of the supporting programs needed to create this application include Microsoft Office PowerPoint 2019, iSpring Suite 9, and Website 2 APK Builder, as seen in Figure 2.

After the design stage, enter the script writing stage to be tested on students and a team of experts. These stages include writing and developing a manuscript for JLPT N4 Bunpou Japanese grammar teaching materials. The materials prepared to be included in this application include conversation texts, bunpou material development, and quizzes that are used as practice questions. In making quizzes, researchers used the iSpring Suite 9 Quiz Maker application. This can help in making the quiz display neater and more practical. All these scripts need to be prepared as application databases. The development of material in this application consists of several types, including material in the form of conversation videos, conversation texts that explain the content of the video, and bunpou/grammar related to the video content. Apart from that, there are also quizzes to help train students to better understand the content of the material they have studied independently. This material was taken from several references, namely: Try Nihongo Noryoku Shiken N4 . Ask Publishin. , . Donna Toki Dou Tsukau. Nihongo Hyougenbun Bunkei Jiten . Alc. Press inc. ), . Nihongo Noryoku Shiken JLPT N4 . 2, 2018: Japan Foundatio. , and w. The Structure of the Application This application was developed as a learning medium that helps convey JLPT N4 grammar Asyhar . states that the criteria for making learning media include clear and neat, clean, attractive, suitable for the target, relevant to the topic taught, under the learning objectives, practical, flexible, good quality, and size appropriate for the learning environment. Therefore, this application was created as much as possible to meet user needs as a learning medium for JLPT N4 Bunpou. This application is made as attractive as possible because an interesting learning media will make students more enthusiastic about learning and understanding the material. In creating learning media, a thorough concept and plan are needed so that the media produces benefits that can be felt by various groups. Not only does it make it easier for teachers to convey the material, but students will also understand the material presented by the teacher. Therefore, structured delivery can also support the delivery of learning material well to students. So, the design structure of this application was created to make it easier for researchers to develop applications that can be useful for their users.
