Abstract

An ERP system is a comprehensive software solution that facilitates the integration of all resources inside a firm. PT Cranium Royal Aditama is a company specializing in the development of Enterprise Resource Planning (ERP) solutions for other businesses. The ERP system of Cranium was constructed on the .Net architecture. Nevertheless, the situation remains unchanged. The Net framework is constrained by its compatibility exclusively with the Windows operating system. Cranium developed a cloud-based ERP system using Java programming language to ensure flexibility and compatibility with all operating systems. The backend of the ERP system is constructed utilizing a monolithic modular architecture, employing Java Springboot as a framework and PostgreSQL as the database. The purchasing, inventory control, and production planning modules are responsible for the design and development process. The design and development of the ERP system backend is now underway, however it is still in the development stage and is currently confined to a basic CRUD technique

Abstract

Campaigns significantly influence candidate electability. Presidential debates, a key campaign strategy, generate extensive public comments on social media, reflecting voter sentiment. This study employs VADER for automated sentiment labeling and Naïve Bayes for classification, analyzing comments from the KPU and Najwa Shihab YouTube channels. Electability data were sourced from national survey reports for correlation analysis. Pearson correlation results indicate that positive sentiment has a moderate negative correlation with electability, while negative sentiment shows a strong positive correlation. This suggests that negative sentiment in YouTube comments is more indicative of a candidate’s rising electability, whereas positive sentiment does not necessarily translate into increased support. The Naïve Bayes model achieved 65% accuracy, 59% precision, 57% recall, and 57% F1-score when including neutral comments. Excluding neutral comments improved accuracy to 77%, with 68% precision, 68% recall, and 67% F1-score. The dataset comprised 17,872 comments, ensuring a robust sample. Despite these findings, limitations exist, such as potential biases in sentiment classification and representativeness, as social media users may not fully reflect the general voting population. Furthermore, while correlation is established, causality remains uncertain, requiring further research. This study enhances the understanding of social media sentiment in political campaigns and highlights the importance of integrating online sentiment analysis with traditional polling methods for a comprehensive assessment of electability.
