Abstract

E-Office Desa is a web-based and mobile-based application that has been integrated for Village Apparatus within the Regional Government of Sumedang Regency which provides convenience in the administrative management process, one of which is correspondence. Based on the results of interviews with a number of village officials, they stated that this application was not entirely easy to use. Related to this, the form of testing from the aspect of convenience can use user experience methods, such as System Usability Scale (SUS), Software Usability Measurement Inventory (SUMI), Net Promote Score (NPS) and User Experience Questionnere (UEQ). SUMI, NPS, SUS methods have shortcomings when assessing the perception of user subjectivity and deep insight, while these problems can be overcome by the UEQ method. Evaluation of user experience testing is done to see how satisfied the user experience is when using the village e-office application. This research focuses on the use of the Village E-Office application in Cibugel Sub-district because based on data, mail management services are still below other sub-districts, which is around 2,689 letters for 4 years. The obtained values for each aspect of UEQ are attractiveness 1.577, Perspicuity 1.822, efficiency 1.684, Dependability 1.597, stimulation 1.591 and novelty 1.581. This shows that all aspects of user experience get a positive impression with the UEQ method. The results of this study can be used as recommendations for future user experience improvements by innovating in various aspects.

Abstract

Assessment of learning outcomes is an important part of education because it serves as a means to determine students' competency achievements. Many educational institutions still use conventional methods or written exams with paper and writing instruments for assessment. This method is ineffective in terms of time and cost and cannot prevent cheating during the exam. This challenge is also faced by SMP NU Darul Falah Subang. One solution to address these problems is to utilize information systems through the development of an Online Exam application. The method used in developing this application is Extreme Programming (XP). The XP method was chosen because it requires relatively short development time, is flexible, cost-effective, and suitable for use by small-scale teams. The aim of this research is to implement the Extreme Programming (XP) method in the development of an Online Exam application.

Abstract

Official travel is a routine activity carried out by state officials, both central and regional. The administrative process carried out during official travel begins with a letter of application for official travel. The application letter that has been approved by the Head of the Regional Work Unit will receive a disposition sheet addressed to the employee. The problem that occurs is that there is an uneven distribution of official travel, where only certain employees are always assigned. Apart from that, official travel costs that are paid in advance before departure trigger the problem of indifferent attitudes in the process of preparing accountability reports. Therefore, a new business process is needed so that this problem does not occur again.

Abstract

The escalating cost of healthcare necessitates accurate prediction methods for determining medical insurance premiums. This research compares the performance of three nonlinear regression models, namely Polynomial, Ridge, and Lasso, in estimating individual health insurance costs. The research process follows the CRISP-DM framework, which includes the stages of business understanding, data processing, modeling, and evaluation. The dataset used is the Medical Cost Personal Dataset from Kaggle, containing 1,338 individual data points with seven demographic and behavioral features. Six outliers in the BMI and charges features were removed using the IQR method, while categorical features were encoded with One Hot Encoding. Numerical features were transformed using second-degree Polynomial Features to capture nonlinear relationships, and then the data was split into 80% training and 20% testing. Evaluation used the Mean Squared Error (MSE) and R-squared (R²) metrics. The results indicate Ridge Regression yielded the best performance with an R² value of 0.857 and an MSE of 2.35×10⁷. This model is more stable and effective in handling multicollinearity compared to the other two models. Nevertheless, the average prediction error of approximately USD 4,800 suggests the need for increased accuracy through parameter tuning or data augmentation before being implemented in a real business environment.
