Abstract

The increased use of PDF files as a medium for cyberattacks has created significant challenges in data security, especially in terms of detection and mitigation of malware threats designed for data theft. This research aims to analyze malware threats in PDF files using static and dynamic analysis approaches to identify patterns that characterize malicious activity that could result in sensitive information leakage. Through static analysis, this research identifies specific elements in the PDF file structure, such as metadata, signatures, as well as malicious indicators that are usually hidden within scripts and encapsulated objects. On the other hand, dynamic analysis is performed by utilizing a sandbox environment to monitor the runtime behavior of PDF files, including network activity, file system access. The results show that the combination of static and dynamic analysis is able to provide more comprehensive detection, where static analysis is effective in quickly identifying signs of malware, while dynamic analysis provides deeper insights into malware behavior patterns that are not detected by static analysis alone.This research provides a static and dynamic analysis-based framework for malware identification on PDF files, as well as providing insights into the effectiveness of these methods in the context of modern data security. The findings of this research have the potential to support the development of security systems

Abstract

Waste management remains one of the most pressing environmental challenges in many regions, including Ternate City. The persistent practice of open dumping has led to severe environmental and public health impacts. This study aims to design and develop a Waste Reporting and Monitoring Application as a technology-based solution to enhance community participation and improve waste management effectiveness. The system was developed using the Prototype Method, allowing iterative development through continuous user feedback to ensure the final product meets actual needs. The application was built using the Laravel framework and modeled through a Use Case Diagram to represent user interactions within the system. Testing with the Black Box method confirmed that all system functions operated effectively, including report submission, photo uploads, and real-time monitoring. The implementation of this application has increased community engagement in reporting waste accumulation and assisted local authorities in responding more efficiently and systematically. Therefore, the system is expected to serve as a concrete step toward reducing open dumping practices and promoting sustainable environmental management in Ternate City
