Abstract

This research presents the development of a real-time attendance system utilizing facial recognition, which incorporates three main components: the MobileNet Convolutional Neural Network (CNN) for classification, Multi-task Cascaded Convolutional Networks (MTCNN) for face detection, and Contrast Limited Adaptive Histogram Equalization (CLAHE) for image preprocessing. The model was trained on a curated subset of the Labeled Faces in the Wild (LFW) dataset, containing 20 categories with 50 images each, and evaluated using a locally captured dataset. Training was conducted on Google Colab using a pre-trained MobileNet model that was fine-tuned with 800 images, while 200 images were used for validation. System performance was assessed through several metrics, including accuracy, precision, recall, F1-score, and a confusion matrix. The model achieved a validation accuracy of 86% and an average F1-score of 0.85, reflecting high classification accuracy. To enhance usability, the system was implemented within a Python-based graphical user interface (GUI), which automates attendance tracking and records data directly into Excel spreadsheets. This study highlights the potential of integrating lightweight CNN architectures with effective preprocessing techniques and real-time GUI applications to create a reliable, efficient, and practical biometric attendance system

Abstract

In recent years, public interest in skincare has significantly increased, especially among younger generations. Although various skincare applications offering skin analysis features are already available, most of them still have limitations. These include product recommendations that are focused only on specific brands, the lack of validation by dermatologists, and the absence of a fully integrated skincare solution within a single platform. This study aims to develop a mobile skincare application called Skintopia, with a focus on user needs through the application of the User-Centered Design (UCD) method. The System Usability Scale (SUS) evaluation results showed scores of 92 from skincare users and 89 from dermatologists. Both scores fall under the “Excellent” category, receiving a grade of A and classified within the “acceptable” level of acceptability. These findings indicate that the UI/UX design of the Skintopia application successfully meets user needs and provides an intuitive and user-friendly experience.

Abstract

The rapid development of the digital era has encouraged MSME (Micro, Small, and Medium Enterprises) owners to adopt technology to enhance business efficiency and effectiveness. Lalungguh Ecoprint, an MSME engaged in sustainable fashion through the use of natural-based ecoprint techniques, still encountered obstacles in product promotion and manual financial record-keeping. This study aimed to develop a website that integrates product catalog management with financial recording into a unified, more efficient system. The development process employed the Waterfall method to ensure a structured and systematic workflow. Laravel was chosen as the primary framework due to its support for the Model-View-Controller (MVC) architecture, which simplifies code organization and modular feature development. MySQL was utilized as the database management system for its reliability in managing complex data storage. The resulting website enables real-time, centralized management of product and financial data and is accessible across multiple devices. This system is expected to enhance operational efficiency, streamline business activities, and broaden Lalungguh Ecoprint’s marketing reach through a digital platform.

Abstract

Thesis administration at the higher education level, such as in the Physics Study Program, still faces challenges due to the absence of an integrated system. To address this issue, a web-based Thesis Management Application was developed to support five main user roles: Students, Lecturers, Thesis Coordinators, Program Coordinators, and Administrators. The system offers a comprehensive set of features including authentication, pre-proposal submission, advisor scheduling, seminar and exam management, publication submission, oral examinations, and final graduation requirements. This study focuses on the Quality Assurance (QA) process using the Scrum methodology and Software Testing Life Cycle (STLC) framework over six sprints conducted within three months. The process began with the mapping of 225 functional requirements on the Front-End and 206 on the Back-End, which were then translated into 1240 test cases derived from various usage scenarios, authorization validations, and interaction flow explorations. Non-functional testing was also conducted at the end of the sixth sprint, covering aspects such as portability, usability, performance, availability, and security. The results show that all system requirements were successfully met, indicating that the application is feasible for supporting a structured thesis administration process.

Abstract

A rule-based expert system was a computational model designed to emulate expert decision-making using a knowledge base and inference algorithms. This research developed a rule-based expert system model with a backward chaining algorithm to diagnose skin diseases based on clinical symptoms. Backward chaining, a goal-driven inference method, started with a disease hypothesis (e.g., psoriasis) and verified related symptoms (e.g., kemerahan, sisik keperakan), enabling efficient differentiation of skin diseases with overlapping symptoms, such as dermatitis, psoriasis, and scabies. The model provided advantages in handling uncertainty, produced accurate diagnoses, and supporting interactive symptom verification. Developed using a knowledge base from credible sources like WHO and AAD, the model was intended to assist in clinical decision-making. The results showed that the backward chaining algorithm effectively improved the accuracy and efficiency of diagnosing skin diseases based on patient-reported symptoms

Abstract

Effective inventory management is one of the keys to a company's success, especially in the retail and distribution sectors that are highly dependent on product availability according to market demand. One common problem faced in inventory management is deadstock, which is a condition where a product is not sold for a long time, causing a buildup of goods and financial losses. This problem is generally caused by inaccuracy in predicting product sales needs. This study aims to overcome this problem by implementing the Adaptive Response Rate Exponential Smoothing (ARRES) algorithm combined with the Grid Search optimization method to improve the accuracy of sales predictions. By utilizing the Sales Data Analysis dataset from Kaggle, the algorithm is implemented in a web-based system using Python and Flask. The results showed that the combination of Grid Search and ARRES was able to significantly increase prediction accuracy, as indicated by a decrease in the MAPE value from 2.845% (ARRES only ) to 0.877% (Grid Search + ARRES). This proves that the proposed method can help companies manage stock more efficiently, reduce the risk of deadstock, and increase the effectiveness of product sales planning
