Abstract

Traditional Sasak weaving in Lombok faces major challenges such as counterfeit products, lack of supply chain transparency, and price disparities, all of which undermine sustainability and consumer trust. Blockchain technology offers potential solutions by improving transparency, security, and data integrity. However, adoption among weaving MSMEs (Micro, Small, and Medium Enterprises) remains limited due to low digital literacy and limited awareness of blockchain’s benefits. This study evaluates the acceptance of blockchain technology among traditional weaving MSMEs in Lombok using an Extended Technology Acceptance Model (TAM). Beyond the standard constructs Perceived Usefulness (PU) and Perceived Ease of Use (PEU) the model integrates Perceived Trust (PT), Perceived Privacy (PP), Perceived Security (PS), Social Influence (SI), and Customer Satisfaction (CS). A quantitative survey was conducted with 50 MSME actors in Sukarara, Lombok. Findings show that PEU significantly influences PU (path coefficient = 0.798; t = 11.520; p < 0.001), while Attitude Toward Using (ATU) strongly affects Behavioral Intention to Use (BITU) (path coefficient = 0.775; t = 5.147; p < 0.001). Both PS and PP significantly impact PT, with path coefficients of 0.410 and 0.380, respectively. Conversely, SI and CS have no significant effect on BITU. The model demonstrates strong explanatory power, with R² values of 81.7% for ATU and 80.7% for BITU. These results highlight that technical factors particularly usability and trust are more influential than social factors in determining blockchain adoption. The study recommends simplifying technology, improving digital literacy, and ensuring policy support to drive wider adoption among traditional MSMEs.

Abstract

Based on WHO data from 2024, Indonesia ranks second after India as the country with the highest number of tuberculosis (TB) cases in the world. Low patient adherence to regular medication intake, caused by the weakness of manual monitoring systems by healthcare workers, remains a major challenge in TB control. This study aims to develop a mobile application to monitor tuberculosis treatment and improve patient medication adherence. The application was developed using a software engineering approach with the Personal Extreme Programming (PXP) method, involving stages of planning, design, implementation, and iterative testing. Data collection techniques included observation, structured interviews, and User Acceptance Testing (UAT) through an online Likert-scale-based questionnaire. The outcome of this study is a mobile-based application featuring medication reminders, daily consumption reporting, monitoring by healthcare workers, and the provision of educational information. Black-box testing results indicated that all application features functioned as intended, while UAT results showed that the application is user-friendly and supports healthcare workers in effectively monitoring patient treatment. These findings demonstrate that the application can serve as a digital solution to improve TB treatment adherence and strengthen medication monitoring systems, particularly in high-burden areas.

Abstract

Mataram University Hospital faces problems in managing work schedules that are still manual using excel and are not integrated with the attendance system. This has an impact on operational management in hospitals that are less than optimal. This research aims to produce an adaptive scheduling and attendance system display that is integrated with the registration module in the Hospital Management Information System (HMIS). The method used to build the system is the User Centered Design (UCD) Method integrated with the Extreme Programming (XP) Method, which includes the stages of user identification, identification of user needs, design and testing iteratively. Data was collected through observation and interviews with the hospital and analyzed qualitatively. Our findings resulted in the appearance of a scheduling and attendance system that aims to optimize operational management in hospitals. Testing the system interface using Usability Testing Method, System Usability Scale (SUS) and User Experience Questionnaire (UEQ) to test the functionality and user experience conducted to 30 respondents consisting of staff and doctors. The SUS test results obtained a score of 76.41 and the “Good” category for all aspects of the UEQ test. Overall, the system has a good level of usability and user experience. This system successfully optimizes operational management in hospitals.

Abstract

Nusa Tenggara Barat (NTB) memiliki potensi besar di sektor pariwisata dengan kontribusi 19,5% terhadap pendapatan daerah. Namun, rendahnya keterampilan Bahasa Korea dan literasi digital masyarakat serta pelaku UKM menjadi hambatan dalam pelayanan wisatawan, khususnya asal Korea Selatan, dan promosi produk lokal. Padahal, kemampuan berbahasa Korea sangat penting untuk memperkuat interaksi, pengalaman wisatawan, promosi budaya, dan perluasan pasar produk lokal. Untuk menjawab tantangan tersebut, Universitas Mataram melalui Program KKN Internasional bekerja sama dengan Seoul National University Social Responsibility (SNU-SR) dan Universitas Nasional (UNAS). Program ini mencakup pelatihan Bahasa Korea praktis, pengembangan konten digital, strategi pemasaran berbasis media sosial, serta personal branding bagi UKM. Tahapan pelaksanaan meliputi sosialisasi, seleksi, pelatihan hybrid (online–offline), pendampingan, evaluasi, dan pembentukan komunitas keberlanjutan. Hasil yang diharapkan meliputi peningkatan kemampuan komunikasi dasar Bahasa Korea, keterampilan produksi konten digital, penguatan branding usaha, serta terbentuknya komunitas pasca pelatihan. Survei menunjukkan program ini efektif meningkatkan daya saing pariwisata NTB, terutama dalam menarik wisatawan Korea Selatan, sekaligus memperkuat posisi daerah dalam pariwisata dan ekonomi kreatif.

Abstract

This paper presents the design and evaluation of a user-centered registration module for a hospital information system, implemented with a microservices architecture to enable independent development and seamless integration of registration, scheduling, and payment services. A prototype was assessed with 50 participants using the System Usability Scale (SUS) and the User Experience Questionnaire (UEQ). The prototype achieved a SUS score of 78.9, indicating good usability. UEQ results showed excellent ratings in attractiveness, efficiency, stimulation, and novelty, while clarity and dependability scored good, revealing opportunities to improve navigation and instructional messaging. The modular microservices approach enhances scalability, maintainability, and performance. Future work will incorporate load testing, integration testing, and accessibility evaluations to further optimize system robustness and user satisfaction.

Abstract

This study aims to optimize the hospital payment process at Mataram University Hospital by designing a user-friendly interface for the payment module in the HMIS. Utilizing a combined approach of XP and UCD, the research identifies opportunities to enhance user experience and streamline payment transactions. Data collection involved literature reviews, staff interviews, and observations, highlighting user needs and system limitations. The redesigned payment module is intended to facilitate structured patient transaction management while ensuring accurate financial reporting. Initial prototype testing using SUS and UEQ methods showed high usability scores, with the SUS score reaching 82 with an “excellent” grade scale and 5 out of 6 aspects of UEQ falling within the “Excellent” category range, indicating that the design was in the top 10%. The novelty aspect is in the "Good" category, indicating that 10% of other systems score better and 75% of other systems score worse. Although it did not reach “Excellent”, the system still showed an adequate level of novelty.
