Abstract

Kegiatan pengabdian masyarakat ini dilatarbelakangi oleh pesatnya perkembangan teknologi digital dan dukungan terhadap masterplan Smart City Kota Semarang 2021-2026. Masalah utama yang ditemukan di Kelurahan Pedurungan Tengah adalah proses administrasi kependudukan yang masih bersifat manual, sehingga memerlukan digitalisasi untuk meningkatkan efisiensi pelayanan publik. Metode yang digunakan dalam kegiatan ini meliputi tahap identifikasi dan observasi, perancangan serta pengembangan sistem, sosialisasi dan pelatihan kepada 50 warga, hingga tahap implementasi dan evaluasi. Hasil dari kegiatan ini adalah terwujudnya platform digital "RT/RW Online" melalui website resmi https://rt3rw16pedteng.my.id/users/home yang memungkinkan warga melakukan pengajuan surat secara mandiri. Kesimpulannya, implementasi sistem ini berhasil mengoptimalkan pelayanan publik dengan mengubah sistem manual menjadi digital yang lebih transparan dan cepat. Meskipun demikian, variasi tingkat literasi digital di antara warga tetap memerlukan pendampingan intensif sebagai langkah keberlanjutan program.Kata kunci: Administrasi Kependudukan, Digitalisasi, Pelayanan Publik, Pedurungan Tengah, Smart City.

Abstract

 This study examines the implementation of Amazon Web Services (AWS) in the MEKATEK pharmacy cashier management system to address the limitations of traditional systems, such as slow transaction processing, data loss risks, and challenges in handling transaction surges. The prototyping method was employed, involving user requirements analysis through interviews and observations, followed by iterative development of core features like inventory management, transactions, reporting, and data backups. Black box testing demonstrated a 100% success rate for core functionalities. Performance analysis recorded stable CPU utilisation below 5% under normal workloads and the ability to handle throughput up to 2532 packets/minute. System optimisation reduced AWS operational costs to IDR 150,000–160,000 per month. AWS implementation improved operational efficiency, strengthened data security through encryption and role-based access control, and minimised human errors. Initial user feedback indicated faster workflows, although adjustments are needed for users with limited technical backgrounds. This study recommends further development, including AI-based analytics and digital payment integration, to enhance MEKATEK’s functionality and competitiveness in the future.

Abstract

To improve the efficiency and transparency of the management of facilities and infrastructure at the Semarang City Youth and Sports Office, a web-based rental system was developed with the RAD approach. Evaluation using the time measurement technique showed that the booking process time was reduced from 10 minutes to 3 minutes, and payment validation, which previously took up to 1 hour, now takes place automatically in seconds. The system was built using Express.js based on Node.js for an efficient and structured backend, React.js for an interactive and responsive frontend, and MySQL as the main database. The system design uses visual aids such as use case diagrams, activity diagrams, and entity relationship diagrams. Testing was carried out using black box testing using the equivalence partitioning technique. As a result, the system meets all functional requirements and increases operational efficiency by up to 70% through payment gateway integration. Further development, it is recommended to add reporting and analysis features to support decision making.

Abstract

Web-based public service applications in the digital governance era are increasingly vulnerable to cyber threats. This study analyzes the vulnerability of the Semarang City Road Information System website quantitatively using the Vulnerability Assessment and Penetration Testing (VAPT) method to evaluate its effectiveness in identifying security gaps. This system is part of an e-government service providing road infrastructure information but, like other technology-based systems, is susceptible to exploitation. The VAPT method used includes two main stages: Vulnerability Assessment to identify weaknesses and Penetration Testing to simulate attacks. The study identified 5 potential vulnerabilities: SQL Injection, Credit Card Number Disclosure, Insecure Direct Object Reference (IDOR), Cross-Site Scripting (XSS), and Error Message on Page. However, 80% of these were false positives, effectively filtered by Alibaba Cloud’s Web Application Firewall (WAF). The IDOR vulnerability was confirmed as valid, allowing unauthorized access to sensitive data through manipulation of the ID parameter in the URL. The original contribution of this research is the specific recommendation for implementing Indirect Object References mechanisms such as ID encryption, as well as emphasizing the need for comprehensive routine testing to improve security and prevent potential data misuse.

Abstract

Containerized environments present significant security challenges due to their shared kernel architecture, which may be exploited as an entry point for infiltration attacks. One common vulnerability is Command Injection, enabling post-exploitation activities that are difficult to detect using conventional signature-based mechanisms. This study aims to implement and evaluate an active mitigation mechanism based on behavioral analysis by integrating the Linux Audit Daemon (Auditd) and CrowdSec within a Podman container environment. The research adopts an Experimental Security Testing approach by developing a Custom Process Bouncer that specifically monitors the execve system call to identify process relationships and automatically terminate malicious processes. Test results against four detection scenarios demonstrate that the proposed mechanism successfully reconstructed the attack process chain through PID cascade analysis and detected six malicious processes generated during the Command Injection scenario. All identified processes were automatically terminated with precision, causing the reverse shell session to be interrupted. These findings conclude that the integration of Auditd, CrowdSec, and the Custom Process Bouncer effectively neutralizes post-exploitation activities reliant on binary file execution, though further development is required to address fileless execution tactics.

Abstract

The development of information technology has penetrated various areas. This is driven by improved service, rapid increase in information needs and decision making. General elections that are held every time always leave problems about securities and speed of recapitulation. This is because the process is done in the traditional way. This research tries to apply blockchain technology to the e-Voting system security engineering process so that it creates a votes recapitulation process that is fast, accurate and accompanied by transparency values to maintain the reliability of the existing vote and maintain the confidentiality of the vote data being transacted. Transparency and confidentiality of voter data is a fundamental value in general elections or voting that must exist. Seeing this, blockchain technology deserves to be applied because the principles that needed can be met by applying this technology to the e-Voting system.

Abstract

Container systems are type of virtualization technology with isolated environment. The isolated environment in container system does not make cyber attacks impossible to occur. In this research, containers in which a cyber incident occurred were forensically tested on the container's memory to obtain digital evidence. The forensic process is carried out using standards from NIST framework with the stages of collection, examination, analysis and reporting. The forensic process begins by performing a checkpoint on the container to obtain information from the container's memory. In Podman the checkpoint process is carried out on one of the containers and will produce a file in .tar.gz form, where this file contains the information contained in the container. After the checkpoint process is complete, forensics is then carried out by reading the checkpoint file using a tool called checkpointctl. Forensic results showed that the container was running a malicious program in the form of a backdoor with a PHP extension.
