INTRODUCTION
Multimedia interacts with users through 3D sound perception and media (Chirivella and Gagliardo, 2016). This multimedia design application refers to a collection of computer-based media with communication system features to build, store, convey, and receive information in the form of audio, video, text, and graphics (Pringsewu, 2018). In this multimedia application, nutrition education and dealing with stress are obtained based on health experts' information. Nutrition education is designed to facilitate a series of nutritional learning conducive to health and well-being with the desired results (Murimi et al., 2017). Meanwhile, prolonged stress causes poor physical and mental health. Understanding personality and stress is important for avoiding stress during a pandemic. An online survey conducted by Liu et al. found that neuroticism and extroversion were higher in association with higher stress levels during a pandemic (Liu et al., 2017).
Previous research that discusses technology shows that technological developments with computer applications have become a viable medium for gathering information and disseminating information in recent years. Information is provided on nutrition training to provide education that makes information more accessible (Kolasa et al., 2017). Other research supporters use multimedia as an attractive educational medium with high effectiveness for various groups, especially children in delivering health messages [6]. This study focuses on the use of nutrition education using multimedia technology to educate students to observe behaviour towards food to be consumed (Hedaoo and Vali, 2015). In another case, multimedia is also used as a medium for providing calorie systems that can classify food objects on a plate by calculating the overall calories of each object produced at a high level of accuracy (Peddi et al., 2017). One example of a health problem caused by food is obesity because it is influenced by irregular lifestyle behaviour and generally occurs throughout the world (Wyatt et al., 2006). Based on research conducted by Tallon et al., obesity is a serious problem because it is increasing in society due to a lack of malnutrition literacy to help prevent it by evaluating the use of multimedia in implementing multimedia as a medium for nutrition education for Portuguese adolescents and Portuguese society. The result was an 85.5% increase in knowledge identified through a questionnaire (Tallon et al., 2020).
This research aims to design a multimedia application prototype for balanced nutrition education and stress management. The research method used qualitative methods by taking and analysing existing data to resolve the situation. The multimedia development method used is the Multimedia Development Life Cycle (MDLC), which consists of six stages. The interview data collection method was carried out by asking questions to informants related to the research topic.

METHODS
The research method used qualitative methods, namely taking and analysing existing data to solve the situation from health experts' data. The data collection method is carried out by interview by asking questions to sources or informants related to the research topic. The multimedia development method used is the Multimedia Development Life Cycle (MDLC), which consists of six stages: concept, design, material collection, application development, testing, and distribution. With an explanation of the two initial stages of multimedia development at the concept and design stages as follows: 1) Concept Learning media is made with the concept of presenting nutritional education learning materials and dealing with stress in an interactive form that can help the learning process.
Creating a multimedia application for nutrition education and dealing with stress can increase interest because the material presented is more interesting.

2) Design
The learning companion application's design stage starts with designing the application through the application menu's structure uses case, sequence, and activity diagrams. Then, create a design nutrition learning and stress application management of interface display.

3) Testing
The results of application testing using the Black Box Test technique, all menu functions in the application have been successful following their respective functions.

RESULTS AND DISCUSSION
In the early stages, content material related to stress management was collected through interviews with resource persons. Besides, literature studies were conducted to complement the data. Existing data are selected and sorted according to their usefulness, analysed, and then adjusted according to content needs. It means that there is a data reduction process, data simplification. However, it does not reduce the comprehensive side of the material to be delivered.
The data is then mapped by doing a mind mapping navigation system, which presents a system map to be created. This is closely related to the user interface that will be created. After completing the system design process followed. The process is as follows: a. Application design with use case diagrams Use case diagrams are used to model and state the functions of the system's services to users. In this nutrition education and stress management application, there is only one user, namely the user. Users can interact and take action on a system that has a scenario in it. The following is a use case diagram of a multimedia application for nutrition education and stress management, which is depicted in Figure 1. See  b. Application design with sequence diagrams Sequence diagrams are used to illustrate the interaction of objects and people in the form of messages depicted with time. The order is from the vertical dimension (time) and the horizontal dimension (related object). The following is a sequence diagram of the use case sequence used in the multimedia application nutrition education and dealing with stress, the sequence diagram of selecting the Home menu is shown in Figure 2. c. The sequence diagram of selecting the Education Nutrition menu is shown in Figure 3.   The next step is application design with activity diagrams. Activity diagrams are used to explain the sequence of activities in this Application Multimedia Nutrition Education and Stress Management. There are several components, namely the Action state to represent the process carried out by an element, with the following explanation: • Action state for the first action executed.
• Action state final for the last action executed.
• Swimlane for the visual area in the activity diagram. • Decision making is done to select the control flow according to the conditions. • Concurrency selects multiple transitions at once. Finally, the visualization, the following table is a multimedia application for nutrition education and stress management that is made. The menu as follows.

CONCLUSION
Multimedia is a means that bridges the delivery of messages to the public through various stimuli to be easily accepted. In the manufacturing process, aspects of navigation, system, communication, and design have interdependent roles. The success of multimedia cannot be separated from user experience and user interface because humans/audiences tend to like something that has been patterned. Designing this multimedia application as an interactive learning media to provide education about the importance of balanced nutrition and stress management, with the hope of overcoming the problem of increased stress due to the Covid-19 pandemic.
