Abstract

Netflix is one of the most popular subscription video-on-demand (SVoD) platforms, offering a wide range of authentic, high-quality content and features that allow users to select, enjoy, and share their viewing experiences on social media. Despite its popularity, Netflix often receives complaints from users, including issues with accessing the application and various features related to viewing activities. The aim of this study is to evaluate the user experience of the Netflix application and provide recommendations for improvement based on data analysis. To achieve this, the HEART Metrics are utilized, which focus on the user's perspective, and apply the Importance-Performance Analysis (IPA) method to map performance and identify improvement priorities. The research reveals several areas that require enhancement, particularly three priority variables: the Happiness variable (Hp3), indicated by the statement "I like the appearance of the Netflix application"; the Retention variable, represented by "I enjoy using the features of the Netflix application"; and the Task Success variable (Ts4), reflected in "I can save movies in the Netflix application." To improve user satisfaction, Netflix can incorporate both light and dark themes, creating a more user-friendly interface. This update could enhance navigation, increase time spent on the platform, promote recommendations, and encourage subscription renewals.

Abstract

In the era of rapid digitalization, the economic sector, especially small and medium enterprises, is required to adapt to the development of digitalization. SDS YPMM Cooperative is one example of a small business that still relies on traditional systems in its business processes. To overcome this problem, a website-based User Interface (UI) and User Experience (UX) design was carried out to digitize the SDS YPMM cooperative business process. In the design, the User Centered Design method is used which focuses on user needs. This method is done by Specify the context of use, specify user and organizational requirements, produce design solutions, and evaluate design against user requirements. At the evaluation stage, the System Usability Scale (SUS) was used to measure the level of usability of the resulting design. The evaluation results obtained 179 respondents out of 533 population for the user interface showed a score of 84.97, which falls into the "acceptable" category and a rating of B or "Excellent". Meanwhile, the admin interface received 5 respondents from 5 populations and scored 93, which falls into the "acceptable" category and an A or "Best Imaginable" rating. These findings indicate that the UI/UX design is highly accepted by both categories of users, thereby improving operational efficiency and shopping experience, which creates satisfaction with SDS YPMM cooperative services.

Abstract

Beleven Farma Pharmacy is a place that provides medicines and other health products such as supplements, vitamins and also various health tests. As a newly established pharmacy, no innovations have been made to improve sales strategies. Analysis of purchasing patterns can produce information that helps pharmacies in determining product bundling recommendations as well as determining product layout. This research applies the a priori algorithm method and uses rapidminer tools to identify drug purchasing patterns from transaction data at the Beleven Farma pharmacy. The Knowledge discovery in database (KDD) method is used as a reference in the data processing process. Based on tests carried out by the author, the resulting rules are that if you buy hemaviton you will buy vice with 4% support and 91% confidence and if you buy amoxicillin you will buy paracetamol with 4% support and 64% confidence. Thus, the resulting information can be used to support decision making in determining marketing strategies so as to increase sales at pharmacies.

Abstract

The advancement of technology and the internet has transformed consumer behavior, particularly in online shopping through e-commerce. Shopee, as a leading e-commerce platform in Indonesia, accounted for 51% of total e-commerce visits from February to April 2024, thanks to its integration of usability principles in its User Interface (UI) and User Experience (UX). In a highly competitive e-commerce landscape, usability is a key factor influencing purchasing decisions, as an optimal user experience can enhance trust and reduce shopping cart abandonment. This study evaluates the impact of usability, based on Nielsen’s Attributes of Usability (NAU), on consumer purchase intention on Shopee. A quantitative survey method was employed, involving 100 active Shopee users in Palembang. Data was collected through an online questionnaire and analyzed using multiple linear regression. The results indicate that efficiency, memorability, and satisfaction significantly influence purchase intention, with efficiency having a negative impact, while memorability and satisfaction have positive effects. Meanwhile, learnability and errors were found to have no significant effect. From a practical perspective, Shopee and other e-commerce platforms should optimize memorability and satisfaction in UI/UX design—such as through personalized interfaces and enhanced accessibility—to improve user experience, drive purchase intention, and strengthen customer loyalty in an increasingly competitive market.

Abstract

The development of information technology in the digital era has had a significant impact, including on online transportation services such as Grab. However, Grab users frequently complain about slow response times from customer support when handling complaints, as well as recurring issues with the balance feature, as reflected in complaints like "saldo" (balance) and "please fix this". This study aims to identify the factors influencing the service quality of the Grab application on user satisfaction in Palembang using the Service Quality (SERVQUAL) approach. A quantitative research method was employed, involving 106 respondents who are Grab users. Data were collected through questionnaires and analyzed using Partial Least Squares-Structural Equation Modeling (PLS-SEM) with SmartPLS 4 to measure the impact of five SERVQUAL dimensions: responsiveness, reliability, tangibles, empathy, and assurance. The findings indicate that these five dimensions collectively have a highly significant effect on service quality (F = 41.92). Individually, the tangibles dimension has the most dominant impact (t = 4.473, p < 0.05), followed by empathy, which also shows a significant influence (t = 2.248, p < 0.05). However, reliability, responsiveness, and assurance do not exhibit significant effects. These results highlight the need for service quality improvements, particularly in the dimensions that were found to be less significant, to enhance the Grab application’s user experience in Palembang.
