Abstract

This study aims to evaluate the effect of information system quality on the level of user satisfaction of the Regional Financial Management Information System (SIPKD), with reference to the DeLone and McLean Model framework. The subject of this research is the State Civil Apparatus (ASN) who works within the East Jakarta Administrative City Government. The DeLone and McLean model is used as a basis for assessing how the quality of information, systems, and services affects usage intensity, user satisfaction, and individual performance. The approach used was quantitative, with data collection through distributing questionnaires to 100 respondents. Data analysis was conducted using the Structural Equation Modeling (SEM) method with the help of Partial Least Squares (SmartPLS) software. The results of the analysis show that information quality significantly affects user satisfaction, but does not show a significant effect on usage intensity. Meanwhile, system quality and service quality are proven to have a significant effect on usage intensity, but not on user satisfaction. Intensity of use has a positive and significant impact both on user satisfaction and on improving individual performance. In addition, user satisfaction is also proven to have a significant effect on individual performance.

Abstract

Lung cancer is one of the leading causes of global mortality, often difficult to detect early due to its nonspecific initial symptoms. This study proposes a Machine Learning-based approach to classify lung cancer risks using the Random Forest algorithm optimized with GridSearchCV. The identified research gap is the lack of interactive web-based implementations that deliver real-time classification results with a user-friendly interface for general users. The objective of this study is to develop an accurate and efficient classification model and integrate it into a web application using Streamlit. The dataset was sourced from Kaggle, consisting of 5,000 patient records and 18 clinical and lifestyle-related features. The preprocessing steps included data cleaning, normalization, encoding, and feature recategorization. Model performance evaluation using Accuracy, Precision, Recall, and F1-Score metrics showed an accuracy of 90%. Feature importance analysis identified smoking habits, throat discomfort, and respiratory issues as dominant predictors of lung cancer. The model was then deployed into a Streamlit-based web application and tested via a User Acceptance Test (UAT) involving 50 respondents, resulting in a Mean Opinion Score (MOS) average above 84%. These findings indicate that the developed prediction system is not only technically accurate but also well-accepted by users, highlighting its potential as a practical and efficient tool for early lung cancer screening.

Abstract

This study aims to analyze user preferences for Action, Horror, and Romance film genres in video streaming services by implementing a Gemini AI-based Collaborative Filtering algorithm. Data were obtained from 1,017 respondents through an online survey using a 1–5 Likert scale. The research stages include data cleansing, calculating genre similarity using cosine similarity, and implementing an item-based Collaborative Filtering algorithm. Furthermore, Gemini AI embedding was applied, which is the process of transforming each genre into a high-dimensional numerical vector representation to more accurately capture semantic relationships between genres. The results show that Action is the most preferred genre, while the highest similarity score between genres was found between Horror and Romance. The developed recommendation system successfully mapped genre similarities and provided relevant viewing suggestions based on other users’ preferences. The system achieved an effectiveness rate of 62.38%. These findings can serve as a foundation for developing more adaptive and personalized recommendation systems in the future.
