Abstract

Palm oil plantations are one of the strategic sectors in Indonesia’s agribusiness industry. To support production efficiency and effectiveness, a predictive model capable of accurately estimating production volume based on supporting factors is required. This study aims to develop a prediction model for palm oil production using the Multiple Linear Regression algorithm by utilizing variables such as land area (Ha), number of trees, and rainfall. The data were obtained from the operational reports of PT. Surya Argolika Reksa. The model evaluation was conducted using two data splitting scenarios: 80:20 and 70:30. The evaluation results show that for the 80:20 test data, the MAE value was 30,095.68, the MSE was 1,533,325,063.46, and the RMSE was 39,151.33. Meanwhile, for the 70:30 test data, the MAE value was 35,455.01, the MSE was 2,096,902,404.44, and the RMSE was 45,791.95. These values indicate the level of prediction error of the model in units of palm oil production. This research contributes to supporting more accurate production planning in the palm oil plantation sector based on data analysis.

Abstract

Padamu Jaya Bersama is a company engaged in the sale of oil palm fertilizer and currently relies on manual transaction recording. This approach leads to various challenges, such as the risk of data loss, delays in information access, and inefficiencies in business monitoring processes. This study aims to address these issues by designing a digital recording system based on a Progressive Web App (PWA) optimized through the Human-Centered Design (HCD) approach. The HCD method is applied through the stages of inspiration, ideation, implementation, and testing, involving business owners and employees as the primary users. The interface design is created using low-fidelity wireframes developed with the Balsamiq tool to illustrate the basic structure and navigation flow of the system. The application is developed using HTML, PHP, CSS, and JavaScript technologies, featuring key functions such as sales recording, stock management, and report generation. Testing results indicate that the designed system improves recording efficiency, accelerates access to sales data, and facilitates business monitoring for the owner. This study concludes that the HCD approach is effective in producing a system that meets user needs.

Abstract

The rapid development of digital technology has increased the demand for high-quality user interface (UI) and user experience (UX) design in online services, including the Riau University (UNRI) Digital Library, which has been available since 2016 as an academic resource platform. An evaluation using the User Experience Questionnaire (UEQ) revealed weaknesses in attractiveness and novelty, which reduced user satisfaction. This study aims to redesign the UI/UX of the UNRI Digital Library mobile application by applying the auto layout feature in Figma with the Five Planes framework (strategy, scope, structure, skeleton, surface). The research employed a mixed approach, including literature study, interviews with the library administrator, and UEQ surveys distributed to 100 active students as primary users. The redesigned prototype was evaluated with UEQ, and the results indicated improvement across all dimensions, particularly in attractiveness and novelty, which previously scored negative. The integration of auto layout enhanced design efficiency and consistency. The findings demonstrate that applying the Five Planes method supported by responsive design features can produce a more modern, intuitive, and engaging interface. This study provides practical implications for the development of digital library systems and theoretical contributions to mobile-based UI/UX design research.
