Abstract

The provision of accessibility of public facilities is necessary to realize equal rights for people with disabilities. To fulfill this, the Research and Community Service Agency of the Faculty of Medicine, University of Brawijaya proposes the Disability-Friendly Motorcycles (Toradi) project. Toradi is a motorcycle that has been modified by adding a sidecar that functions as a pillion and is designed to be easily accessed by people with disabilities. They also want Toradi to become an online transportation business because so far people with disabilities have experienced difficulties when using online transportation services that are already available. The difficulty is due to drivers who often refuse orders when they know their condition. Therefore in this research, an Android-based online transportation application will be built which can connect the disabled people with Toradi and making it easier for them to do mobility. The application development uses a prototyping method that helps developers to explore system requirements more easily. The application was developed using the Kotlin programming language with an object-oriented approach. Then the application is tested with functional testing and compatibility testing. Functional test results indicate that the application is valid. The compatibility test results show the application can run on Android devices with a version above 5. Furthermore, the application is evaluated by the user based on the system acceptance criteria and gets a value of 93.6% which can be concluded that the application can be well received by the user.

Abstract

Analytical Chemistry Laboratory is one of the seven laboratories in the Chemistry Department. One of the activities in analytical chemistry laboratory is to test the level of hydroquinone solution. Hydroquinone is a compound that is toxic when inhaled by the nose and in direct contact with eyes and skin. Hydroquinone analysis using spectrophotometry method is one method that is fast compared to other methods but in determining the level of hydroquinone solution using the UV spectrophotometry method must understand the use of UV spectrophotometer so it requires time to learn the use of the instrument. In using a UV spectrophotometer the device must wait for 30 minutes after the device is turned on to perform a calibration so that it can be used in conducting analysis. In this research, the authors developed an application based on Android-based levels of hydroquinone solution to assist in analyzing the levels of hydroquinone solutions using RGB color codes from smartphone camera photo results which were then performed calculations using lambert-beer law in determining the levels of hydroquinone solutions. The application is built using the prototyping method because the requirements of the system have not been fully defined at the beginning. The results of functional tests which include unit testing, integration, and validation obtained 100% valid results. The results of non-functional testing are compatibility testing with system results that can be run on the Android operating system with a minimum version of 7.0 to 10.0.

Abstract

High or low usability level of an application is tested by usability testing. Usability testing is used to test the level of usability of the system. This researcher uses the System Usability Scale (SUS) Method to answer research questions about user satisfaction. SUS was chosen because in this method the testing is done by involving the end user, where testing with this method is more emphasis on the point of view of the end user so the test results will be more in accordance with what is faced by the user. The number of complaints from PLN Mobile users is the main reason for testing the usability section of this application. The usability test results on PLN Mobile is 22.77% where the user is still not satisfied with PLN Mobile so the assessment given is not good. Improvement with the discovery prototyping method will collect improvement suggestions from users with a direct interview that will be made into a prototype improvement reference which will then be tested again. Suggestions for improvements obtained from respondents such as adding settings that can change the user's personal language and personal data stored in the application, improving the layout of features, placing the most important options and grouping menus in icons that are easy to understand on the main page. The usability testing result on prototype is 85.26%. Comparison of test results has increased by 62.49%.
