Abstract

Based on the results of a survey by Kurious and Populix, a healthy lifestyle starting to become a focus and trend in Indonesia. These surveys reveal people's understanding of healthy food, with the problems that arise. Even though many people understand its benefits, there is still a gap between understanding and healthy practices, especially among the productive age group (25-44 years). Difficulty maintaining consistency in a healthy eating pattern is a challenge faced. The solutions provided from the survey results show that 64 percent of Indonesian people use healthy catering services to maintain consistent healthy lifestyle patterns. Therefore, the idea of developing the YumHealth startup emerged to help people start eating better, with a focus on catering services and delivery service features, nutritional consultations, education through articles,and a BMI calculator. This research will focus on implementing these features using a Design Thinking approach and testing using the Usability Testing method. Apart from that, the potential of the online market in Indonesia is also an encouragement to develop this application. This research aims to provide adequate solutions to existing problems and improve user experience. Based on the results of Usability Testing with 30 respondents, the final result was 71.5, which means the application prototype is in a good grade. The testing results also provide suggestions such as the use of typography (fonts), and visualization in education, as well as adding features such as guide pages and TDEE calculators.

Abstract

Kopi Hening is a coffee business in Salatiga City managed by individuals who are deaf or hard of hearing. Facing challenges in customer communication and manual bookkeeping processes, this study aims to design a prototype UI/UX for an inclusive cashier application to enhance operational efficiency and bookkeeping accuracy. Using the Design Science Research Methodology (DSRM) approach, the study involved direct observation of cashier activities, interviews with supervisors, and design evaluation through simulations using the Cognitive Walkthrough method. The Cognitive Walkthrough evaluation, which measured user success rates in completing specific tasks, showed good performance with transaction scenarios achieving 83-86% success rates (cash payment 83%, transfer 83%, QRIS 86%) and financial bookkeeping scenarios reaching 73%. Expert evaluations confirmed that the design adheres to inclusive UI/UX principles, though further adjustments, such as optimizing text size and element spacing, are recommended for better accessibility. This study serves as an initial step toward supporting digital inclusion and provides a foundation for the future development of inclusive cashier applications.

Abstract

Entrepreneurship represents a viable option for persons with disabilities as it offers opportunities to accommodate their needs, build independence, determine their work patterns, avoid discrimination, foster personal development, and contribute positively to the lives of others. Thus, Entrepreneurs with Disabilities (EWDs) play a significant role in realizing the commitments of the Sustainable Development Goals (SDGs), particularly in achieving inclusive and sustainable economic growth, employment opportunities, and decent work for all. This study aims to explore the sustainable strategies adopted by “Kopi Hening” to maintain business continuity. The research is exploratory in nature and adopts a qualitative approach to obtain an in-depth understanding of the “Kopi Hening” phenomenon. Data were collected through data triangulation, which involved interviews, observations, and documentation. The data were analyzed inductively to derive emerging themes, and their validity was ensured through triangulation and member checks to enhance the credibility and trustworthiness of the findings. The findings reveal that the strategies include external support, self-development, a sense of ownership, uniqueness, product evaluation, partnership, and effective financial management. Facilitators play a crucial role in supporting the sustainability of EWDs, as it has been noted that EWDs greatly depend on external support. However, this study has limitations, as it is based on a case study and needs more diverse EWD respondents. Future research should expand the number of respondents by involving the government. Additionally, future studies could focus on the role of applied technology in supporting EWDs, particularly deaf individuals, to address communication barriers through technological solutions.
