DESIGNING UI/UX OF DOCTOR'S CONSULTATION APPLICATION USING DESIGN THINKING METHOD

: For all people in the world, the application of information and communication technology has become something that is used in everyday life. All information can be accessed easily using current developments in various technologies. The process of searching for various information on the internet has become a habit of today's society. One of the information that people often seek is about health. Several available online health consultation service applications provide considerable benefits for all users. One method used for the UI and UX design process is design thinking. The average user of the application is 18-35 years old. The user interface provided in this application is not yet user friendly, especially for the elderly. User interface (UI) and user experience (UX) are important so that users feel comfortable when using an application.


INTRODUCTION
One of the information that is often sought by the public is about health.One way to maintain health is done by consulting with health experts.Currently, there are various websites or applications that provide online health service offerings [1].Some of the current online health consultation services include Alo Dokter, Klik Dokter, and Halodoc.App users are 18-35 years old on average.In fact, someone over the age of 35 also needs to use an online health consultation service application.Some users complain if they still find it difficult to use the application.The user interface provided in the application is not yet user-friendly, especially for the elderly.An elderly person certainly needs the help of those closest to him in operating health service applications.Seeing these conditions, UI/UX design innovations are needed that facilitate the use of healthcare applications [2].One of the methods used for the UI and UX design process is design thinking.Design Thinking is an approach that focuses on user needs for innovation, thus making an application product better because it provides effective solutions to problems [3].
As for some previous studies used as literature review material, the research was conducted by [4] explained the complexity of the features in the doctor's click and SUS testing was carried out to determine the application's user satisfac tion score.
Further performed by [5] condu cting data analysis with PLS techniques in the Alodokter application, The results of this study only provide input to broaden their views in increasing interest in using the Alodokter application.
Research by [6] Analyze the design of the Alodokter application then provide recommendations so that the application is even better.
Research by [7] Data was collec ted as many as 300 comments from several applications.The analysis results showed that the lowest number of negative comments was Doctor Click, with an accuracy rate of 98.57%.Follow ed by Halodoc with an accuracy rate of 82.86%, and Alodokter with an accuracy rate of 62.86%.
Research by [8] conducted analy sis using IBM SPSS Statistics 26 involving 107 samples.The results showed a significance value of less than 0.05, indicating that optimizing the spre ad of ads across various digital channels is a top priority to increase user awaren ess of healthcare applications.
Research by [9] Evaluation using User Experience Questionnaire (UEQ) via Google Form with 20 participants showed that the comparison between the Halodoc application was considered posit ive, while Alodokter was quite positive.
Research by [10] perform analy sis on the application telemedicine From feedback, there was 112.013 positive sentiment, 34.853 neutral sentiment, and 97.228 negative sentiment.
Research by [12] Taking the ques tionnaire 412 responses showed factors such as Information Quality, Usability, Ease of Use, and others affecting the User Satisfaction of the HaloDoc app.These findings are useful for stakeholders to improve the quality and usage of the application.
Therefore, this research is differe nt from previous research.If the previous study only discussed the level of satisfaction and analysis of health applica tion users, while this study conducted application analysis and user needs.Not only that, this study also provides suggest ions for the design of doctor consultation applications that can be accessed by all ages.After making the design is complete, testing is carried out using the SEQ method.

METHOD
In this study, a design thinking method was used to create or design UI / UX for doctor counseling applications.This method is known as a compre hensive thinking approach, which focuses on creating solutions that begin with understanding user empathy aimed at producing continuous innovation accord ing to user needs (human centered) [13].Design thinking itself has five stages in designing a product, including emphat ize, define, ideation, prototype, and test

Emphatize
Emphatize or empathy is the initial process in design, this is because empathy is at the core of the usercentered design thinking stage [15].This stage understands the user in the context of the product to be designed by doing several ways such as observation, intervi ews from both of which are combined by providing scenarios first.

Define
Define is a step in clearly defini ng the real problems experienced by users when they use a product.The pro blems identified are the results collected at the emphatize stage which are then analyzed to determine the core problems to be identified [16].

Ideate
Ideate is a stage where it is a tran sitional step from formulating a problem to solving it.At this stage, attention is focused on the creation of ideas or ideas as a foundation in making design proto types.This stage also serves as a moment of identification of user motivations and needs, as well as generating ideas thro ugh the brainstorming process [17].The main goal of this stage is to generate as many new points of view and ideas as possible.

Prototype
Prototype is the process of designi ng or designing a product from the results of ideas or concepts that have been obta ined previously and turned into solutions that will be applied as a prototype, but before going to the prototype stage, resea rchers must make user flow, wireframes, design systems, and mockups first.

Emphatize
In this emphatize process, conduct direct observations and interviews with potential users of the application to be created.Observation is done by observing one of the competitor applications by looking at the rating on the Google Play Store.

Define
In this define stage, the process of preparing the problem is carried out by making paint points and how-might we.Image 2 is the pain point and Image 3 is the result of how-might-we.

From the results of pain points and how-might-we above, conclusions can be drawn for the list of needs as in table 1.

Ideate
This stage is used to provide a solution to a problem.The solution in terms of these problems can be seen in Image 4.

After the ideation stage, the affinity salt is made.Image 5 is an Affinity Diagram.

Affinity Diagram Furthermore, from the results of grouping ideas in the affinity dia-gram process, the next step is to create a user flow that will be used in the application.In this study there are two user flows, namely the doctor's application user flow contained in Image 6 and the consultation history user flow in Image 7 and then in Image 8 there is a profile user flow.

Prototipe
This stage is the process of creating a visual design that will serve as a communication medium for users when interacting with the system.The purpose of creating prototypes is to help designers understand more easily the problems, ideas, and user experiences that occur when interacting with the system.

Wireframe
Wireframes are a basic version of app design that makes it easy for designers to layout elements in an app.The wireframe can be seen in Image 9.

Mockup UI
Mockup is an advanced stage that aims to perfect the wireframe that has been made before.If at the wireframe stage, the appearance is only presented in a simple way using black and white colors only, then at the mockup stage, the product begins to look clearer.Image 10 is a mockup of the UI of this application.

Testing
In the testing process, the Single Ease Question (SEQ) method is used which only contains one general question such as "How do users rate the doctor's consul application?"which is answered on a Likert scale from 1 to 7. The higher the number given by users, the more satisfied they are using the application.Table 2 is the SEQ scoring matrix.This stage involves 5 participants who match the criteria that have been determined previously, each of the participants will test the doctor's consul application that has been prototyped.Table 3 is a test scenario for the doctorconsul application that must be followed by participants.From the results of testing the doctor's consul application which was attended by 5 participants from 11 tasks, with a rating scale of 1-7 to determine how effective the doctor's consul application was used, getting an average of 73.4.The score is then divided again by the number of tasks, the final result is 6.67.Soit can be concluded that the design of this doctor's consultation application falls into the category of easy-to-understand use.
After testing the doctor's consul application, it produces an overall score in table 4.
