Draw learning in early childhood is an important lesson and full of stimulation of the process of growth and development of children which could help to train the fine motor skills. We have had a lot of applications that can be used to perform learning, including interactive learning applications. Referring to the observations that have been conducted showed that the experiences given by the applications that exist today are very diverse and have not been able to represent the model of learning and characteristics of early childhood (4-6 years). Based on the results, Hierarchical Task Analysis method generated a list of tasks that must be done in designing an user interface that represents the user experience in draw learning. Then by using the Heuristic Evaluation method the usability of the model has fulfilled a very good level of understanding and also it can be enhanced and produce a better model.

Traffic jams that occur in big cities in Indonesia due to the increased use of private vehicles. One solution to overcome this problem is to increase the use of public transport. But, the existing public transport is still not much in demand by the community. Some people express their opinions regarding the use of city public transportation via Twitter. Â The opinions can be processed as a sentiment analysis to determine the positive opinions and negative opinions. The opinion will then be analyzed to determine factors that are the main cause of the ineligibility use of public transport as well as the factors that make the public choose to use this type of transport. By upgrading of facilities and services based on the results of sentiment analysis, it is expected that people will switch to use city public transportation, which would reduce the traffic jam. Â This research used SVM method to process sentiment analysis. The result has shown SVM accuracy reaches 78.12%, which indicates that the results of this reserach deserve to be considered.

One of the public facilities that use websites is the hospital. However, there are some shortcomings complained by users related to the hospital website, which is the lack of information, confusing view of the menu, etc. Therefore, we need the information architecture to manage related content and website structure. The build of information architecture is done by using a bottom-up approach in card sorting. There are five stages in the research, which the first stage is a strategy to equalize the goal in the development of the hospital website either from the point of view of the organization or company and the user's point of view of the hospital website. The second stage is a scope to find out what are the needs of the user in order to build the hospital website. The third stage is structure, which is the formation of the initial structure of information architecture by using a bottom-up approach to the card sorting method. The type of card sorting that is commonly used is the open card sorting. The fourth stage is the skeleton stage, which is used to make information architecture model design using wireframe and prototype. The fifth stage is the test using findability testing and usability testing. From the test, the design of information architecture is made to fulfill the desires and needs of users, as proven by the results of findability testing achieved 15.9 seconds, and the results of usability testing achieved 80.33. Hence, by the results of these tests, it can be concluded that the design of information architecture at the hospital website has a good value from findability testing and usability testing.

Interactive media convey information through videos or images that can move with computer control in their presentation. Interactive media have a positive effect on children's language development. A language is a tool that humans need to communicate with each other. With the development of technology, especially in communication, Indonesian people have begun to learn English which is used as a means of communication between nations around the world. According to the English Proficiency Index, Indonesia will be ranked 80th out of 112 countries in the world in 2021. This shows that Indonesia is included in the low ability group. One of the efforts to improve English language skills is to introduce basic material from an early age. Children aged 0-6 years quickly absorb and receive various information. This study aims to build a UI modeling of basic English learning applications according to the needs and criteria of kindergarten-age children, which was built using the Child-Centered Design method to analyze the tasks required by the user and evaluate the level of usability using the USE Questionnaire method with a Likert Scale of 1-5. The findings of this study provide user interface design recommendations for basic English learning applications and have a usability score of 88.75. These findings indicate that this application is easy to use and provides a positive experience in learning basic English for kindergarten-age children.

The online transportation ordering mobile application is an application that helps users in ordering transportation facilities that can be accessed by anyone using mobile phones and internet users are no exception for people with visual impairments. Users with visual impairments with limited accessibility will have difficulty accessing the application. Based on the results of the initial survey, it was found that the online grab transportation ordering application is currently still less accessible and an increase in accessibility is needed. This study aims to design the right user experience to improve the accessibility of the application so that users with visual impairments can access the application properly. In this research, the method used is User Centered Design (UCD) which focuses on user needs and characteristics who are visually-impaired users. The study's findings are recommendations for the interaction design of the Grab application. Based on the needs and characteristics of the users, the resulting accessibility improvements are in the form of a simpler design than the previous design and features designed to overcome the pain points of users with visual impairments. Furthermore, the design that has been made is tested using the Cognitive Walkthrough method, which contains user scenarios to achieve certain goals. The evaluation results show that the scenario completion rate has increased and the number of errors made when completing the scenario has also decreased. It can be concluded that using the UCD method can improve the usability of the application.

The development of technology in the world from time to time continues to progress so rapidly that various kinds of tools in the world are now converted into digital tools that facilitate the activities of human life. However, with the development of this technology, unfortunately, it has not had much impact in the realm of Tahfidz Al-Quran. Media Tahfidz Al-Quran, currently available in the community, is to follow a program that learns under the guidance of a teacher or study together in one place. Based on a survey conducted by interviews using several digital Al-Quran applications available in the android play store as a media for Tahfidz Al-Quran. The usability aspect that has not been fulfilled in using digital Al-Quran as a media for Tahfidzul Quran is efficiency and satisfaction. Therefore, to properly use Tahfidz al-Quran in digital form, it is required to have the appropriate UX modeling in line with the needs of Tahfidz Al-Quran. Because Task-Centered System Design (TCSD) method puts a strong emphasis on user demands and task requirements, this study intends to create a design using TCSD.Furthermore, to ensure that the model developed is within the circumstances and user characteristics, the product model outcomes will be assessed using the System Usability Scale (SUS). The findings of this study provide recommendations for the Tahfidz Al-Quran application's user interface design and have an improved usability score at 88.75, which is expected to be a benchmark for the Tahfidz Al-Quran application. Therefore, the TCSD method can also raise the SUS usability value in the application
