Abstract

 Efficient CPU scheduling is essential to reduce waiting time, turnaround time, and maximize throughput. This study conducts a Systematic Literature Review (SLR) to compare FCFS, SJF, RR, and Priority Scheduling based on these metrics (RQ1), and to examine trade-offs between fairness and efficiency across different workload contexts (RQ2). Using the PRISMA method, 7 articles from 2015–2025 were selected from Scopus. Data were synthesized on scheduling performance, and VOSviewer was used for bibliometric mapping. Results show SJF excels in batch environments with lowest waiting (≈15 ms) and turnaround times (≈30 ms). Adaptive RR variants provide high throughput (up to 1200 jobs/s) and low latency in real-time, at a cost of increased context-switch overhead (5–12%). FCFS, although simple, results in high delays. Hybrid algorithms offer a balance between fairness and performance. Bibliometric analysis confirmed dominant research clusters on SJF and RR adaptations.

Abstract

Email spoofing is a form of cybercrime that often occurs by taking advantage of weaknesses in email protocols to deceive recipients through spoofing sender identities. This attack is a serious threat because it can be used to commit fraud, data theft, and the spread of malware. This study aims to analyze email spoofing cases with a digital forensic approach using the National Institute of Justice (NIJ) methodology, which includes five important stages: identification, collection, examination, analysis, and reporting. The main problem studied is the difficulty of detecting fake emails on internal networks that have not implemented modern email authentication mechanisms such as the Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting & Conformance (DMARC). The research method used was qualitative, experimental, with controlled simulation. Some of the tools used in this experiment include Postfix, SWAKS, tcpdump, and Mozilla Thunderbird. In simulations, fake billing emails are sent from fake addresses (e.g. finance@bankxyz.com) through an open SMTP service to see the extent to which spoofing can be done without being detected. During this process, email traffic is recorded, and various digital artifacts such as .eml files, .pcap packet captures, SMTP logs, and PDF attachments are successfully collected for further analysis. The results of forensic analysis showed that there were inconsistencies in the email headers, especially in the Return-Path, From, and Received fields, which were the main indicators of spoofing activity. This study proves that email spoofing is very likely to occur on unprotected systems, so strengthening email server configuration and implementing authentication is an important step. In addition, the NIJ method has proven to be effective in providing a systematic and valid forensic investigation structure, and can be a reference in handling email-based cybercrime cases in the future.

Abstract

The demand for information systems continues to rise in line with the advancement of technology and the changing times. Every industrial sector is now required to adapt, including the hospitality industry. One of the crucial aspects of hotel management is the transaction recording system, particularly related to the management of consumable inventory. To this day, many hotels still rely on conventional methods such as manual bookkeeping or simple spreadsheets. These traditional methods are prone to human error, time-consuming, and make real-time inventory checking and reporting difficult. Given these conditions, there is a need to develop an integrated and efficient inventory information system. This system is designed to facilitate the recording and monitoring of consumable stock availability, including inventory levels and transactions with suppliers. With such a system in place, hotel management can accurately monitor stock levels and plan procurement according to actual needs, avoiding shortages or overstocking. The development of this system follows the stages of the Software Development Life Cycle (SDLC), beginning with the requirement analysis phase. This phase involves gathering information from users, which is then visualized in the form of several design tools: the Use Case Diagram to illustrate the interactions between users and the system, the Entity Relationship Diagram (ERD) to design the database structure, and wireframes of the User Interface to ensure the system is easy to understand and use. The results of this design process indicate that the system being developed meets all user requirements in terms of both functionality and usability. With a well-structured and computerized inventory system, hotel inventory management can be carried out more effectively, efficiently, and with minimal error. Ultimately, this contributes to enhancing overall service quality and operational performance in the hospitality sector.

Abstract

E-commerce and Point of Sale (POS) software are two rapidly evolving technologies in the modern industry, particularly in the food and restaurant business. Along with this development, the need to create more efficient and user-friendly solutions is increasingly pressing. Previously developed systems, which integrate e-commerce and POS, help customers purchase food without having to go directly to the restaurant. However, these systems still have several shortcomings that can be addressed to improve the user experience, especially for consumers who desire more efficient and practical transactions. In this study, the authors focused on further developing the existing system by adding new features to enhance user convenience and satisfaction. One key development is a digital balance storage feature that simplifies transactions, allowing consumers to use their available balance to purchase food. Furthermore, the system will be equipped with a QR code that functions as a customer ID, replacing the more conventional membership card, and will be more efficient in terms of cost and access time. Other improvements include the addition of a points feature, more flexible software authority, strengthened security systems, and improvements in transaction management and reporting. This study used field observation methods, including direct observation and user interviews to gain deeper insights. Utilizing this updated system is expected to increase food sales, improve transaction processes, and provide convenience for customers who want to enjoy restaurant services without any hassles. With the development of an integrated e-commerce and POS system, customers will have a more flexible and convenient purchasing experience.

Abstract

This study aims to analyze the workflow of a digital product purchasing system, focusing on the user login process, admin verification, and product access after payment. The system involves three key actors: the buyer, the system, and the admin, each playing a crucial role in ensuring the security and continuity of transactions. The workflow is designed to minimize transaction errors, ensure data validity, and improve operational efficiency and security in managing digital products. The study employs flowcharts and Unified Modeling Language (UML) diagrams to visually represent the interactions between these actors and the system. The analysis begins with the user login process, where the buyer provides authentication credentials, followed by admin verification to ensure authorized access. Once the payment is processed, the system verifies the transaction and grants the buyer access to the digital product. Each step is mapped using flowcharts to depict the sequential actions and decision points within the system, while UML diagrams provide a more detailed view of system architecture and interactions. The findings reveal that the system is designed to mitigate errors through structured validation and secure data handling, enhancing the overall purchasing experience. Additionally, the admin's role is critical in overseeing transaction approval and ensuring that digital products are accurately delivered. The study highlights the importance of system design in supporting smooth transactions, fostering user trust, and maintaining high levels of security. This analysis is valuable for improving the design and performance of digital product purchasing systems in various e-commerce settings.
