Abstract

The development of information technology has driven digitalization in various sectors, including in the procurement of government goods and services through the E-purchasing system. ASHA Store is one of the business actors that utilizes the e-Catalog and Mbizmarket platforms in carrying out transaction processes with government agencies. However, in its implementation, the information system used also creates various operational risks that can disrupt the smooth running of the business. This study aims to analyze the risk management of the information system implemented by ASHA Store using the ISO 31000:2018 framework. The method used is a descriptive qualitative approach with data collection techniques in the form of interviews, observations, and documentation. The results of the study showed that there were ten main risks identified, including internet connection disruptions, inaccessible applications, and delays in updating product data and shipping goods. These risks were then analyzed based on their likelihood and impact, so that mitigation priorities were obtained. Control measures were carried out with strategies such as increasing staff training, providing backup networks, and implementing dual authentication and data backup SOPs. By conducting periodic evaluation and monitoring, the implementation of ISO 31000-based risk management has proven effective in helping ASHA Store identify, analyze, and control information system risks systematically and sustainably.

Abstract

Information retrieval (IR) is a field in computer science that focuses on searching and retrieving relevant information from large-scale data sets. With the development of technology and the explosion of digital information, the need for efficient and accurate IR systems is increasing. This study aims to examine various IR models, both classical and modern, and the supporting techniques used in the information retrieval process. Classical models such as the Boolean Model, Vector Space Model (VSM), and BM25 are the initial foundations of IR systems, while modern neural network-based approaches such as DSSM, DPR, and Retrieval-Augmented Generation (RAG) offer more semantic and contextual search performance. In addition, basic techniques such as indexing and tokenization, as well as advanced techniques such as query expansion and relevance feedback, are also discussed, which also increase the effectiveness of the system. The performance evaluation of the IR system is carried out using various metrics such as precision, recall, F1-score, MAP, and NDCG. The results of this study indicate that the combination of the right IR models and techniques can produce an information retrieval system that is more relevant, efficient, and adaptive to the needs of modern users.

Abstract

The Backyard Villa is a medium-scale lodging business that relies on manual booking methods like text messages and phone calls. This approach leads to various issues, including delayed confirmations, data duplication or loss, and limited access to information for prospective guests. These inefficiencies negatively impact the operational effectiveness and overall service quality. This study aims to design and implement a web-based reservation information system to enhance service performance and competitiveness in the digital era. The system was developed using the waterfall method, which includes requirement analysis, system design, implementation, and testing phases. The system defines two main types of users—guests and admins with different access rights and features. System functionality testing was conducted on 28 scenarios, covering the booking process, villa data management, and reporting. The test results demonstrated a 100% success rate. The system not only simplifies the reservation process for customers through self-service but also supports the management in handling booking data, customer information, and operational reports more efficiently. The implementation of this system is expected to significantly improve the operational efficiency and service quality of The Backyard Villa by automating manual tasks, reducing errors, and providing a better user experience for both guests and management.

Abstract

Understanding informatics logic is an important foundation in programming learning because it plays a role in shaping algorithmic and computational thinking patterns. However, various studies show that students often experience difficulties in understanding the concepts of propositional logic, inference, predicate logic, Boolean algebra, and their application in program control structures. This article aims to conduct a systematic literature review of related studies to obtain a comprehensive picture of the conceptual and practical challenges faced by students, as well as the learning strategies used to overcome them. The research method uses a Systematic Literature Review (SLR) approach by analyzing relevant and open access articles published between 2017 and 2025. The results of the study indicate a gap between mastery of logic theory and its application in program code. Key findings include misconceptions in propositional logic, difficulties in simplifying Boolean algebra, limited representation skills through flowcharts and pseudocode, weak computational thinking, and recurring errors such as off-by-one errors and variable misconceptions. This study emphasizes the importance of integrating logic teaching with programming, a practice-based approach, and the use of visual media and interactive technology to improve student understanding.
