Abstract

Coronavirus disease was first discovered in the city of Wuhan, China in December 2019. Due to the impact of the new coronavirus infection, many infected patients have died including in the United States. Data obtained from the official web of Data Centers for Disease Control and Prevention shows a high mortality rate due to Covid-19. This study aims to analyze the Covid-19 mortality rate by region using the Agglomerative Hierarchical Clustering (AHC) method and find the optimal cluster validity using the Silhouette Index (SI) method. Clustering the Covid-19 death rate using the AHC method is needed to understand the pattern of death rates due to Covid-19 and assist in making policies for pandemic prevention and handling. This research resulted in the optimal number of clusters at n clusters = 2 with cluster-1 high mortality rate of 12,307 object and cluster-2 low mortality rate of 13,498 object. The results of this study can thoroughly analyze Covid-19 death data such as revealing some important findings and input that can be proposed to improve the quality of response to future pandemics.

Abstract

This research aims to develop an Android mobile-based cashier application system at Toko Nay Sahabat Alam. The store currently does not have a system that facilitates the sales transaction process, inventory management, and sales and purchase history in a structured manner, which results in less efficient business processes and the risk of operational errors. The proposed cashier application is designed to optimize the sales transaction process, stock inventory management, and display sales and purchase history. The system architecture is implemented using Rest API, with the backend developed using Laravel framework and MySQL database management system. Android mobile application development using Flutter. The development methodology used is agile. Testing is done using the black-box testing method and the results show that all application features run as expected. End-user testing was also conducted using a questionnaire to measure user satisfaction with the application. The questionnaire results showed that most users were satisfied with this application as a whole, with 57.1% of respondents giving the highest score of 5, 35.7% giving a score of 4, and 7.1% giving a neutral score of 3. The system implementation results can improve operational efficiency, minimize errors in the transaction process, and facilitate more effective transaction and inventory data management.

Abstract

The current government policy is directed towards strengthening the MSME sector to achieve sustainable economic growth. The Ecoprint MSME in Lampung faces several challenges in maintaining the continuity of its business, including a decline in sales, limited capital and raw materials, as well as the unstable demand for ecoprint products, especially those that are still relatively new. This instability makes it difficult for MSMEs to manage inventory, which hinders the production process. The research method to address the issue of applying Business Intelligence in the strategy for developing superior products in ecoprint MSMEs using the Apriori Algorithm can be approached through Business Intelligence methods. The data used in this study is sales transaction data from June to August 2024. The stages of applying Business Intelligence include Justification, Planning, Business Analysis, Design, and Construction. By applying Business Intelligence and the Apriori Algorithm, MSMEs can compete in the digital era and achieve sustainable success. Based on testing results using Rapidminer, three association rules were obtained: Dress, Hijab with a support of 57% and confidence of 100%; Hijab, Dress with a support of 57% and confidence of 80%; and Hijab, Accessories with a support of 57% and confidence of 80%. The Apriori algorithm is capable of identifying consumer purchase patterns, allowing MSMEs to determine the most in-demand products and adjust their production strategy accordingly. The application of the Apriori algorithm on transaction data has resulted in various unique association rules. The key difference between these rules lies in the combinations of related products. Further analysis shows that the performance of the Apriori algorithm is optimal when using a minimum support value of 50% and a minimum confidence of 80%.

Abstract

This research aims to develop a mobile-based makeup artist reservation system at Tanti Makeup Studio to overcome the limitations of conventional booking methods. The current manual reservation system through phone calls or walk-ins has caused several challenges, including scheduling conflicts, inaccurate booking records, lack of visibility into incoming reservations, and operational inefficiencies that hinder business growth. This research utilizes Agile methodology, which incorporates iterative development cycles and continuous feedback integration. Data collection used primary sources through interviews and direct observation, and secondary sources through literature study. The system development process includes requirements analysis, conceptual design, and is followed by implementation and black box testing. The results showed successful implementation of key features including user authentication, package management, scheduling, and payment processing, with all components achieving conformance in functionality testing. The mobile app effectively streamlines the booking process, improves operational efficiency, and enhances customer experience through an intuitive interface and integrated payment system. User validation through a survey of 51 respondents showed strong positive results: 80.4% rated the application as overall easy to use (51% “very easy” and 29.4% “easy”), 86.2% gave high ratings for ease of booking (52.9% highest rating, 33.3% second highest), 80.4% expressed satisfaction with the integrated payment system, 86.3% reported improved time efficiency in the booking process, and 82.4% felt that the confirmation and scheduling process became more efficient. This study concludes that the implemented system successfully overcame the initial challenges of the manual booking process, providing a comprehensive solution for both service providers and customers in the makeup service industry

Abstract

This research focuses on the development of a performance dashboard application to measure Key Performance Indicators (KPIs) such as the Customer Satisfaction Index (CSI) and Net Promoter Score (NPS). The main issue is the inaccurate measurement of customer satisfaction, making it difficult for management to make the right decisions in designing business strategies. The system development methodology is the Rapid Application Development (RAD) approach, which allows for quick and efficient application development. This system enables the company to effectively monitor and analyze performance data that can aid in better decision-making. With the information provided by this system, the company can adjust its business strategies to improve customer satisfaction, increase loyalty, and achieve its business goals. The research findings show that this dashboard system can provide more accurate insights into customer satisfaction and loyalty, which in turn helps the company improve service performance, address weak areas, and plan more measurable strategic steps to effectively achieve business goals
