Abstract

This research aims to analyze Android malware "UndanganPernikahan.apk" using static methods with reverse engineering techniques and dynamic analysis. The analysis process uses several tools to understand the characteristics, behavior, and impact of the malware after installation on an Android device. The research shows that this malware covertly steals user credentials through several vulnerabilities. The "UndanganPernikahan" malware is a type of spyware disguised as a wedding invitation and runs in the background without the user's knowledge. To avoid similar malware infections, it is recommended to always update the system and applications, only download applications from trusted sources, and conduct digital security training.

Abstract

Information technology advancement has significantly impacted Indonesia's education sector, including the University of Mataram. The university relies on the Sistem Informasi Akademik (SIA) for various academic activities. However, increasing users has led to challenges such as excessive traffic and server downtime. This research analyzes the impact of DDoS attacks on the SIA server's performance and utilizes Zabbix for server monitoring. The results show that DDoS attacks mainly burden the network traffic component, with a significant increase compared to normal conditions. CPU and RAM resources also increased but less significantly. Monitoring with Zabbix improves the efficiency of performance management, enabling real-time monitoring and easy-to-understand visualization. The findings help administrators identify the need to increase server capacity and implement DDoS detection and mitigation systems to maintain the quality and availability of academic services.

Abstract

Background: In the digital era, cybersecurity is important for universities in protecting academic information and user data. The focus of this research is to identify and analyze the security vulnerabilities of higher education websites in West Nusa Tenggara against three types of attacks, namely SQL Injection, Cross Site Scripting (XSS), and Insecure Direct Object Reference (IDOR), which can compromise the integrity of higher education data and information systems.Objective: This research aims to evaluate the level of vulnerability and severity of the risk of the three types of attacks on the websites of higher education institutions.Methods: This research uses penetration testing methods, and assesses the severity of vulnerabilities based on the Common Vulnerability Scoring System (CVSS) version 3.1.Result: This research results show that 50% of the ten college websites tested are vulnerable to XSS attacks, 30% to SQL Injection, and 20% to IDOR. The highest severity was found in the SQL Injection vulnerability with a CVSS score of 9.0 critical category.Conclusion: The implications of the results of this study indicate that higher education institutions need to immediately strengthen system security with strict input validation, WAF implementation, and adequate authorization mechanisms to prevent future exploitation of similar vulnerabilities.

Abstract

This research analyzes information security risk management on the website of the Regional People's Representative Council (DPRD) of West Nusa Tenggara (NTB) using the COBIT 2019 and NIST 800-30 frameworks. The main objective of this research is to identify weaknesses in existing security controls and provide recommendations for improvements to deal with cyber threats, specifically DDoS, cross-site scripting (XSS), deface, and SQL injection attacks, which can disrupt service availability and data security. The research methods included interviews with five key stakeholders who have responsibilities in information security, as well as the distribution of questionnaires to ten IT staff. Data from the interviews and questionnaires were analyzed using risk mapping according to the COBIT 2019 framework and NIST 800-30 to identify capability gaps. The results showed specific weaknesses in the management of controls against XSS and DDoS threats, especially in the aspects of monitoring and incident response. The research conclusions emphasize the need to improve risk management through the addition of more up-to-date security technology, increased security awareness and training for staff, and regular security audits to ensure the sustainability of risk management. Recommendations include the implementation of a more sophisticated threat detection system, periodic training for staff, and a more structured incident response procedure to improve security and ensure continuity of public services through the DPRD NTB website.

Abstract

This study investigates security vulnerabilities in secondary school PPDB websites, focusing on Structured Query Language (SQL) Injection and Cross Site Scripting (XSS) techniques. The research aims to conduct a security audit and analysis using XSS methods and Insecure Direct Object References (IDOR) penetration tests. The primary objectives are to identify existing security gaps, provide recommendations for improvement, and enhance the overall security of these websites. By addressing these vulnerabilities, the study seeks to make PPDB websites more secure and reliable in protecting users' personal data and maintaining system integrity. Additionally, this research aims to raise awareness among PPDB system managers and schools about the importance of cybersecurity in website development and management, offering practical solutions and serving as a reference for improving website security in the educational sector.

Abstract

Palm sugar (Arenga pinnata Merr.) is a traditional sweetener that has been produced by Indonesian people for a long time and plays an important role in the rural economy. However, the quality of liquid palm sugar is greatly influenced by the easily fermented nature of the sap and the uneven production practices. This community service activity aims to improve the quality and safety of liquid palm sugar through training on Good Manufacturing Practices equipment at the Giri Madia Forest Farmers Group (KTH). The training was held on August 21, 2025, in Giri Madia Village, Lingsar District, West Lombok, with 20 participants. The method included interactive lectures, demonstrations, and hands-on practice focusing on the prerequisites for CPPOB and controlling the liquid palm sugar process using affordable equipment (food-grade containers, stainless steel sieves, thermometers, pH meters, and refractometers for °Brix control). The results of the activity showed a significant increase in participants' understanding of identifying critical control points and implementing proper sanitation procedures. It is hoped that consistent implementation of CPPOB will not only guarantee product quality and safety, but also strengthen the competitiveness of liquid palm sugar in the wider market, while encouraging the strengthening of the local potential-based economy.
