Abstract

This study aims to redesign Virtusee, an employee performance monitoring platform, using the User-Centered Design (UCD) methodology. Virtusee features functionalities such as leave requests, monthly performance tracking, and self-service payslip access. The application, last updated in 2014, was described by users as outdated and not aligned with current trends. Based on the System Usability Scale (SUS) questionnaire, the application scored 40, categorized as poor with a grade of F, indicating the need for significant improvements. Employing the UCD approach, this study prioritized user needs and preferences in the redesign process, following these stages: (1) defining the usage context, (2) identifying user and organizational requirements, (3) design and implementation, and (4) usability evaluation. Testing the new design involved users who had used Virtusee more than once in the past month. The testing scenarios included exploring the new design, completing SUS and QUIS (Questionnaire for User Interaction Satisfaction) surveys via Google Forms, and conducting brief interviews to gather suggestions and critiques. Data were collected through observation, interviews, literature review, and questionnaire dissemination. Results showed a significant improvement, with the SUS score increasing to 80.3, indicating acceptable usability. The QUIS evaluation revealed average scores ranging from 5.9 to 6.8 across various indicators, exceeding the expected median. These findings highlight that the UCD methodology is effective in designing applications that are more user-centered, enhancing productivity and user satisfaction. This study provides valuable insights for developers aiming to create applications that are not only functional but also adaptive to evolving user needs, serving as a reference for designing solutions that align with user-centric principles.

Abstract

Stock price prediction is a crucial component in investment decision-making, enabling investors to plan strategies more accurately and minimize risks. This study applies the Gated Recurrent Unit (GRU) model to predict the stock prices of blue-chip banking companies in Indonesia using data from the period 2019 to 2024. The model utilizes historical stock data to forecast future trends. The results from the first testing scheme, with a data split ratio of 70% / 30%, using GRU units (128,256) with the Adam optimizer, show that the GRU model is the most optimal in terms of prediction, measured by metrics such as MSE, RMSE, and MAPE. This study also proposes a web-based dashboard that visualizes the predicted stock prices and provides decision-support tools for investors. The findings highlight the effectiveness of deep learning in financial forecasting and underscore its potential to enhance investment strategies.

Abstract

This research develops a house price prediction system in Surabaya using the Backpropagation Neural Network (BPNN) method. The dataset was obtained through web scraping of property listings, resulting in 3,435 records with 52 attributes. To improve stability, the target variable (house price) was transformed using natural logarithms. Several neural network architectures were tested, and the best configuration [32, 64, 32] achieved Mean Absolute Error (MAE) of 0.3125, Root Mean Squared Error (RMSE) of 0.4201, R² of 0.7138, and Mean Absolute Percentage Error (MAPE) of 1.46%. A multi-run evaluation of 20 iterations confirmed consistency of results. The model was implemented as a web-based application using Flask, allowing users to predict house prices in real-time. This research shows that BPNN is reliable for property price forecasting and can support decision-making in the housing market.

Abstract

The increasingly competitive business environment required companies to make objective decisions, particularly in determining the feasibility of outlet contract extensions. PT Nitro Pratama Indonesia previously conducted this process manually, which often led to inconsistent decisions. This study aimed to develop a web-based decision support system to evaluate outlet cooperation systematically. A combination of Fuzzy Analytical Hierarchy Process (Fuzzy AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) was applied. Fuzzy AHP was used to determine the weight of criteria under uncertain conditions, while TOPSIS was used to rank alternatives based on their proximity to the ideal solution. The study involved 50 active outlets located in Surabaya and Solo branches. The final criteria weights obtained were Outlet Revenue (0.33), Rental Cost (0.26), Outlet Location (0.16), Accessibility (0.11), Competitiveness (0.08), and Operational Cost (0.06). The ranking process generated objective recommendations that were consistent with manual calculations. Functional testing using Black Box Testing indicated that all system features operated properly. The system proved effective and relevant in supporting accurate and efficient decision-making for outlet contract extensions.

Abstract

This study investigates the applicability of time series forecasting models—Autoregressive Integrated Moving Average (ARIMA) and Simple Exponential Smoothing (SES)—for optimizing raw material planning in traditional songkok production. Utilizing monthly production data from a small-scale manufacturer in East Java, Indonesia (July 2020–August 2024), the ARIMA(1,1,1) model demonstrated superior forecasting performance, particularly under weak and irregular seasonality. Compared to SES, ARIMA yielded lower MAE, MSE, and MAPE values, enabling more precise production planning. The forecasts were translated into raw material requirements, resulting in improved inventory precision and operational efficiency, with monthly material usage gains ranging from 2.05% to 2.18%. These improvements are especially critical for micro-enterprises constrained by limited resources and seasonally driven demand cycles. While the univariate approach is a limitation, the findings provide a foundation for integrating contextual data in future multivariate models. The study offers practical insights for digital transformation in artisanal sectors and contributes to the broader discourse on data-driven production planning in culturally embedded industries.

Abstract

UKKI UPN Veteran Jawa Timur requires an objective and transparent mechanism to determine the best management board members in each organizational period. The evaluation process previously relied on manual calculations using spreadsheets, which was considered ineffective, difficult to interpret, and prone to human error and subjectivity. This study aims to design and develop a web-based Decision Support System (DSS) to assist in selecting the best management board members in a systematic and accurate manner. The research adopts a qualitative approach to identify system requirements through interviews with the general chairman, general secretary, and several relevant stakeholders. System development is conducted using the Waterfall model, which consists of requirements analysis, system design, implementation, testing, deployment, and maintenance stages. The Decision Support System applies the Analytical Hierarchy Process (AHP) to determine criteria weights and the Weighted Product (WP) method to rank the alternatives. The results show that the developed website is capable of managing member data, evaluation criteria, assessment scores, and organizational periods, as well as presenting ranking results in real time. The system enhances efficiency, accuracy, and transparency in determining the best management board members at UKKI UPN Veteran Jawa Timur.
