Abstract

This study explores the transformative potential of big data analytics in the realm of health insurance risk management. Focusing on data sourced from Highmark Health from 2015 to 2018, the research aims to evaluate the efficacy of advanced data manipulation techniques and machine learning models in enhancing predictive accuracy. The analysis involves a comprehensive examination of Health Maintenance Organization (HMO) and Preferred Provider Organization (PPO) plans, with rigorous data preparation processes such as cleaning, aggregation, feature engineering, and outlier handling to ensure model suitability. Four distinct models were developed: an initial model utilizing raw data without outlier treatment, a model post-outlier treatment considering both HMO and PPO members, and models focusing exclusively on HMO and PPO members respectively. Results demonstrated significant improvements in predictive accuracy following outlier treatment, with Random Forest and Multivariate Adaptive Regression Splines showing superior performance. The Random Forest model achieved a Root Mean Square Error (RMSE) of 630.04 and an R-squared value of 0.757, underscoring its robust predictive capabilities. Similarly, the Multivariate Adaptive Regression Splines model exhibited strong fit with commendable metrics. The HMO-focused model yielded promising outcomes with a minimal RMSE of 675.85 and an R-squared value of 0.68. However, the PPO-focused model's suboptimal results highlight potential data quality issues and dataset limitations. This research underscores the critical role of integrating machine learning techniques in health insurance analytics, providing valuable insights for proactive risk management and decision-making, and enhancing efficiency and effectiveness within the industry,

Abstract

Sustainable Development Goal 14 focus on sustainable development in the marine sector by emphasizing key focus areas such as Marine Protected Areas, Total Fisheries Production, Aquaculture Production, and Capture Fisheries Production. The ASEAN region, with its rich marine biodiversity, faces serious threats, including overfishing. However, no interactive platform is currently available to comprehensively visualize relevant data. This research aims to develop a web-based Geographic Information System (GIS) to visualize SDG 14 data in ASEAN using the Extreme Programming approach. This study employs the Research and Development (R&D) method with an Extreme Programming approach, allowing iterative software development. Primary data, including marine protected areas and fisheries production, were obtained from reliable sources such as the World Bank and visualized using Leaflet.js with geospatial data in GeoJSON format. System testing was conducted through Black Box Testing and the System Usability Scale (SUS), integrated into a survey form completed by 32 respondents to assess the system's accuracy and ease of access. The test results indicate that the system can provide accurate and easily accessible information, with a Black Box Testing score of 99.79%. Additionally, the Mean Absolute Percentage Error (MAPE) calculation resulted in a value of 0.21%, demonstrating a very high accuracy in system predictions. The SUS score reached 94.03%, reflecting a very high level of user satisfaction. This system successfully meets the need for SDG 14 data visualization, supports decision-making, and raises public awareness of marine ecosystem conservation in ASEAN.

Abstract

The global adoption of Agile methodologies in virtual IT teams presents a fundamental conflict with the principle of face-to-face communication, with temporal distance posing a primary operational barrier. This research identifies and analyzes the adaptive time-coordination tactics that globally dispersed Agile teams employ to overcome this challenge. The study utilized a qualitative, phenomenological approach, conducting semi-structured interviews with practitioners from teams spanning up to a 15-hour time zone difference. The analysis reveals that effective teams do not force full-day synchronization but instead strategically leverage a limited synchronous ‘overlap window’ for high-bandwidth collaboration. Complementing this, teams implement a disciplined ‘asynchronous handoff’ to create a continuous, 24-hour workflow, transforming temporal separation into a strategic advantage. Key findings also show that teams pragmatically reconfigure Agile ceremonies, often replacing daily stand-ups with asynchronous updates, and foster individual autonomy to maintain productivity. The study concludes that success in virtual Agile environments hinges on a flexible framework of emergent, context-aware tactics rather than rigid adherence to traditional practices. These insights provide actionable strategies for managers to enhance the temporal efficiency and coordination of virtual projects.

Abstract

It is very hard to keep an eye on garbage at the village level when there is no clear information about when sorted waste will be picked up and when sales will happen, and when there is no method for documenting waste data. This lack can cause garbage to build up in places where it shouldn't and make it harder to manage waste properly. To fix these problems, Badan Usaha Milik Kalurahan needs a mobile app that is easy to use and makes waste management tasks easier. BUMKALs are very important for helping communities grow and providing important services, like trash management. This study is all about making a trash management software, with a big focus on User Interface and User Experience principles. The design process uses a User-Centered Design method, which makes sure that users are included in every step. This method makes sure that the final application fits their demands and wants very well. In Caturharjo Village, which is in the Pandak Subdistrict of Bantul Regency, the local BUMKAL has taken the lead in starting community-based garbage management. But they still have problems with keeping track of data in a systematic way and having good ways to communicate. We used the User Experience Questionnaire to find out how users felt about the design of the program and how satisfied they were with it. The evaluation results show that the mobile app had mostly good feedback on all UEQ aspects, such as how clear, beautiful, and useful it was. All of the ratings were over the positive benchmark, which is really impressive. This shows that users were very happy with the application that was made, which means it may be successfully implemented and used.
