Abstract

Determining the best employee is one of the essential processes in improving the quality of human resources within a company. Manual evaluation processes often lead to subjectivity, require considerable time, and may result in less accurate decision-making. This study aims to develop a Recommendation System for Determining the Best Employee using the Simple Additive Weighting (SAW) method as a decision support tool. The SAW method was selected because it is capable of evaluating multiple criteria by considering the importance weight of each criterion. The research stages include requirements identification, determination of criteria and their respective weights, employee data collection, normalization, preference value calculation, and alternative ranking. The developed system is capable of processing employee data in a computerized manner, making the evaluation process faster, more objective, and more efficient. Based on the testing results, the system successfully produced the highest preference value of 0.956, indicating that the employee was selected as the best alternative according to all predefined criteria. The findings demonstrate that the SAW method can be effectively implemented in a recommendation system for determining the best employee and can assist management in making accurate, transparent, and measurable decisions.

Abstract

Digital documents in modern organizations are highly vulnerable to content and metadata manipulation such as modifications to the author name, creation date, and document status which can be altered illegally without detection by conventional systems. This research implements a PDF document integrity verification method that integrates SHA-256 cryptographic hash computation with QR Code visualization using a Hybrid Verification Architecture. The proposed approach works by representing the document binary content and metadata in a sorted canonical string, computing the SHA-256 hash as a document fingerprint before the QR Code is embedded into the PDF, and embedding the hash into a QR Code with Error Correction Level H (30% recovery rate). The hybrid verification architecture employs Two-Layer Hash Verification: (1) QR Code integrity check to detect the presence or absence of QR Code, and (2) hash-to-storage comparison to match the hash extracted from the QR Code against the Local Hash Storage. In the current system version, the PDF content hash is not recomputed during verification; the system focuses on matching the QR hash with the stored hash. Empirical testing was conducted using 75 automated scenarios across 7 testing categories using a synthetic controlled dataset generated programmatically via pdf-lib: valid PDFs, metadata tampering, content modification, QR replacement, QR replay, control PDFs without QR Code, and corrupted QR codes. Results show an overall accuracy of 86.67% (65/75 correct), with 100% detection rate on 6 out of 7 testing categories. The content modification category (0% detection, 10 false positives, FPR 18.18%) is documented as a structural limitation of the current architecture, as the QR hash still matches the stored hash when only content is modified.

Abstract

The rapid growth of internet technology has made access to information easier, but has also opened opportunities for misuse, such as access to online gambling sites and pornographic content through personal mobile phones and laptops. This study aims to implement and evaluate a third-party DNS filtering service integrated with a third-party Android-based monitoring application, configured as an end-user content monitoring and blocking system for such content. The method used is experimental with a modified Network Development Life Cycle (NDLC) approach, covering requirements analysis, system architecture design, DNS filtering configuration, and black box functionality testing. Testing was carried out on domains identified as online gambling sites and adult content to measure blocking effectiveness, response time, and internet connection stability. Results show that the implemented DNS filtering system successfully blocked access to prohibited domains with a high success rate, without significantly affecting internet speed for legitimate domains. The Android-based monitoring application was also able to record and display real-time access logs, although the push notification feature did not function consistently. It is concluded that the integration of DNS filtering and an Android monitoring application is a promising supplementary end-user level cybersecurity solution for restricting access to negative content on personal devices.

Abstract

Student affairs websites have a strategic role as information portals and digital administration services for students in higher education. However, problems related to the interface and user experience often hinder the effectiveness of conveying this information. This research aims to evaluate the level of usability of student affairs websites using a combination of quantitative System Usability Scale (SUS) methods and Usability testing functional testing. SUS testing involved 76 student respondents selected using purposive sampling techniques, while Usability testing measured five aspects of usability. The evaluation results show an average SUS score of 60.16, which categorizes the website into Marginal usability level (OK/Low Acceptable) and is below the standard benchmark value of 68.00. On the other hand, Usability testing results recorded excellent functional performance with an average score of 4.2 to 4.3 in the aspects of Learnability, Efficiency, Memorability, Error Handling and Satisfaction. The gap between marginal global perception and high functional performance shows that even though the main features of the website can operate well, the navigation hierarchy, interface layout and display responsiveness still require improvement. This research provides evidence-based recommendations for improving interface design to improve comfort and optimal user experience.

Abstract

The utilization of transaction data in footwear Micro, Small, and Medium Enterprises (MSMEs) is still often limited to administrative record-keeping, resulting in consumer purchasing patterns being underutilized as a basis for marketing strategies. This study aims to analyze consumer purchasing patterns in a footwear MSME in Binjai Village using the Frequent Pattern Growth (FP-Growth) algorithm and to develop data-driven product bundling recommendations based on actual transaction data. This study employs a quantitative data mining approach using Market Basket Analysis (MBA). The analyzed data consist of 3,549 actual transactions from Importshop Sofie Shoes during January–April 2026. The analysis stages include data cleaning, transformation into a binary matrix using one-hot encoding, frequent itemset extraction using FP-Growth, association rule generation, and evaluation based on support, confidence, and lift ratio. The results show that 3,522 transactions (99.24%) were single-product transactions, while 27 transactions (0.76%) were multiple-product transactions. This finding indicates that consumer purchasing behavior tends to be characterized by targeted shopping. Although multiple-product transactions were relatively limited, parameter adjustment enabled FP-Growth to identify positive association rules, indicated by a lift ratio greater than 1. These findings demonstrate that actual purchasing patterns can be utilized as a basis for developing product bundling and data-driven marketing strategies for footwear MSMEs. The study concludes that FP-Growth can identify relationships between products and support marketing decision-making in MSMEs.

Abstract

Inventory management plays a crucial role in supporting a company's operational activities. Inaccurate restocking decisions may result in either overstock or stock shortages, both of which can negatively affect operational efficiency. This study aims to implement the Fuzzy Tsukamoto algorithm in an inventory restocking prediction system at Telkom Akses Semarang. The system was developed using the Prototype methodology, with CodeIgniter 3 as the web framework and Python for implementing the fuzzy computation process. The prediction model utilizes two input variables, namely outgoing stock and remaining stock, while the output is the recommended restocking quantity. The prediction process consists of fuzzification, rule-based inference, and defuzzification using the weighted average method. Functional testing was conducted using Black Box Testing, while prediction accuracy was evaluated using the Mean Absolute Percentage Error (MAPE). The results indicate that all system functionalities operated as expected. Furthermore, the prediction model achieved a MAPE value of 5.99%, which falls into the highly accurate category. These findings demonstrate that the Fuzzy Tsukamoto algorithm is capable of generating restocking predictions that closely match actual inventory requirements, making it a reliable decision support tool for determining optimal restocking quantities at Telkom Akses Semarang.

Abstract

Dental clinics that still register new patients manually often face long queues, recording errors, and disorganized patient data. This condition is also found at Klinik Dua Dental Care, where patients must come directly to the clinic, fill out forms manually, and wait without certainty regarding queue time. This research aims to design a web-based patient registration management information system for Klinik Dua Dental Care using the Waterfall method, which develops the system sequentially through problem identification, data collection, system design, testing, and evaluation/maintenance stages. The system is designed using Unified Modeling Language (UML) in the form of a Use Case Diagram and Data Flow Diagram (DFD), and is built using ViteJS for the front end, ExpressJS for the back end, and PostgreSQL as the database. The system provides three main features, namely online registration, real-time queue management based on the First In First Out (FIFO) principle for both online and walk-in patients, and structured patient data management. Functional testing using the Black-Box method on eleven test scenarios shows that the features that have been developed, including account registration, login, patient registration, and queue status monitoring, run according to expectations. It can be concluded that this system is expected to shorten the registration process, reduce queues, and improve the quality of service at Klinik Dua Dental Care. User satisfaction testing using a Likert scale involving 15 respondents (patients and administrative staff) across five assessment aspects yielded an overall score of 88.0%, which falls into the "Very Good" category, indicating that the system was well received by its users.

Abstract

An inventory information system is an essential component of asset management that supports organizations in managing, monitoring, and controlling asset data effectively and efficiently. Effective inventory management not only ensures the availability of accurate information but also facilitates decision-making, reporting, and asset supervision. UM-AD Palembang currently relies on manual procedures for recording and managing inventory data. This manual approach has resulted in several problems, including data inaccuracies caused by human error, duplicate records, delays in report preparation, and difficulties in locating or tracking specific assets. Furthermore, manual processes slow down data updates, causing the available information to be less timely and reliable. To address these problems, this study aims to design and develop a web-based inventory information system to improve the quality of asset data management at UM-AD Palembang. The system was developed using the Waterfall method, consisting of requirements analysis, system design, implementation, testing, and maintenance. This development model was selected because it provides a systematic and measurable framework for system development. The outcome of this study is a web-based application that enables more integrated and efficient inventory management. The developed system facilitates faster, easier, and more accurate asset recording and automatically generates asset reports, thereby reducing potential errors and accelerating the reporting process. The implementation of this inventory information system is expected to support administrative activities, improve the effectiveness of asset monitoring, and provide more valid and reliable information for university management in making decisions related to asset management.

Abstract

This study designs and implements a web-based sales information system for PT Putra Indo Mandiri Sejahtera by applying the Multilevel Feedback Queue (MLFQ) algorithm with dynamic time quantum to optimize transaction scheduling based on product urgency levels. The problem addressed is the absence of a transaction processing mechanism that considers product characteristics, causing fresh milk transactions with short shelf lives to be treated equally with processed products such as cheese. A quantitative method was employed with a population of 1,200 transactions and a sample of 300 transactions selected through stratified random sampling. The MLFQ system uses three queue levels mapped according to product shelf life: Q1 for fresh milk and yoghurt, Q2 for gelato, and Q3 for cheese. The dynamic time quantum was calculated from the absolute difference between the mean and median of transaction burst times, yielding tq1 = 141 seconds, tq2 = 282 seconds, and tq3 = 564 seconds. Simulation results show that high-urgency product transactions were processed earlier, while transactions with larger burst times were automatically demoted to the appropriate queue level. The implementation of MLFQ demonstrates improved transaction scheduling efficiency and proportional service quality.
