Information and communication technology has been developed rapidly and affectedvarious aspects such as propagation of information and marketing strategy of tourist attraction. KebunBinatang Ragunan is one of tourist attraction in Indonesia. Aside from recreation area, Kebun BinatangRagunan can be a place to learn animals. However, learning animals itself tends to be less attractive and less interactive. Therefore, an application was developed as one of animal learning media to increase touristmotivation. The application developed in form of quiz game by using gamification like achievement to increase their motivation in animals learning and using Sattolo Shuffle algorithm in order to make quiz more varied. After testing, the application is known affect the Behavioral Intention to Use level around 76.96% and Immersion level around 82.43% in giving motivation and attracting tourist attention to use the application. Sattolo Shuffle algorithm successfully applied in application to produce a unique sequence of each randomized quiz. Keywords—Achievement, Animal Recognition, Gamification, Quiz Game, Sattolo Shuffle.

Administrative services are a routine activity carried out by village and/or sub-district offices andallow for mobility and crowding of residents which should be avoided during the current pandemic.The administrative service procedure requires a series of approvals from the head of the RT, headof the RW, the apparatus and the head of the village/kelurahan so it takes time. Administrativeservices will be very good if they can be carried out electronically using devices that are commonlyowned by citizens such as smart cell phones so that they can be carried out faster, complying withrecommendations to avoid mobility and crowds and the slogan "stay at home" can be implemented.The stages of community service activities carried out started from needs analysis and systemdesign using the waterfall model development method. This activity will be continued at theimplementation stage so that it can be used widely for the community. The development andinstallation of village administration service applications is planned to be based on Android withcentralized data in the cloud. The system design is then verified and validated by a number of users,especially from the kelurahan because those parties are the ones who know the existing serviceprocess. The verification test states that the service process is in accordance with what is neededand the validation test states that the design is in accordance with the user's needs.

During the study of another language such as Japanese, the problem that exists is in remembering each of the characters that is used as writing mechanism. This is happened because the difference with Roman characters and the number of character that exist, is far beyond that of alphabet which makes a visual impairment for those used to write in alphabet. There is a traditional way to remember something which is periodically learn or remember the characters and assign a visual image to each of the characters in order to be remembered easily. Spaced repetition is a method that give an interval during a repetition which is mainly used for someone who want to remember something periodically by learning it for a long term periodically. This research discusses the implementation of one of spaced repetition algorithm called SuperMemo 2 and using it along with a flashcard to learn Japanese characters periodically. Software development methodology used is Waterfall Model, because the requirements used to develop the software is clear at the beginning. Index Terms—Flashcard, Japanese Characters, Language Learning, Spaced Repetition Software, SuperMemo

Proses elisitasi kebutuhan perangkat lunak dengan menggunakan metode agile didasari oleh kebutuhan yang terus berubah seiring dengan berjalannya proses pembangunan perangkat lunak. Agent Based Goal Elicitation (ATABGE) merupakan sebuah teknik elisitasi kebutuhan yang menggunakan pendekatan agile. Teknik ini menggunakan initial goals kemudian mendekomposisinya menjadi subgoals yang dilakukan oleh stakeholder. Namun teknik ini perlu ditinjau kembali pada bagian Pre-Sprint, yang menyatakan bahwa initial goals ditentukan oleh analyst, padahal ini akan menyebabkan kebutuhan yang didapatkan menjadi tidak murni dari stakeholder. Selain itu, pada tahap Sprint, para stakeholder sepertinya perlu untuk diberikan prioritas wewenang untuk menentukan hasil. Secara keseluruhan, penggunaan metode agile juga memiliki beberapa kekurangan, yaitu kesulitan dalam menentukan estimasi biaya sejak awal proyek dan kesulitan dalam menentukan arsitektur perangkat lunak yang akan dibangun. Index Terms—requirement engineering, elicitation, agile, ATABGE, goals, agent

Kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine. Kidneys are vital organs contained in the human body and serve to filter the blood of metabolic waste product and throw it in the form of urine. Given the changing conditions in the body can affect the kidneys, causing a decrease in the function of these organ and lead to chronic kidney disease. In an article on the website of the National Institute of Diabetes and Digestive and Kidney Diseases (2014) argued that chronic kidney disease is a silent disease, in which patients appear normal and show no symptomp but the test results stating the patient’s kidney function had decreased. Based on the above information, the research on how to detect chronic kidney disease will be conducted. Applications built on the basis of desktop and using Decision Tree algorithm C4.5. The trial was conducted to determine how much the level of accuracy that can be generated by the application.
