Abstract

This research proposes a novel method for detecting artificial intelligence (AI)-generated essays by integrating the bidirectional encoder representations from transformers (BERT) model with particle swarm optimization (PSO). Unlike traditional approaches that rely on manual hyperparameter tuning, this study introduces a systematic optimization technique using PSO to improve BERT’s performance in identifying AI-generated content. The key problem addressed is the lack of effective, real-time detection systems that preserve academic integrity amidst rapid AI advancements. This optimization enhances the model’s detection accuracy and operational efficiency. The research dataset consisted of 46,246 essays, which, after data cleaning, were refined to 44,868. The model was then tested on 9,250 essays. Initial evaluations showed BERT's accuracy ranging from 83% to 94%. After being optimized with PSO, the model achieved an accuracy of 98%, an F1-score of 98.31%, precision of 97.75%, and recall of 98.87%. The model was deployed using a FastAPI-based web interface, enabling real-time detection and providing users with an efficient way to quickly verify text authenticity. This research contributes a scalable, automated solution for AI-generated text detection and offers promising implications for its application in various academic and digital content verification contexts.

Abstract

This study evaluates the performance of PT. XYZ, a prominent ready-mix concrete company in Toba Regency, North Sumatra, Indonesia, from 2018 to 2022. Utilizing a descriptive and quantitative research approach, data were gathered through document analysis, questionnaires, and interviews. The findings reveal significant financial weaknesses, particularly in the total asset turnover, return on investment (ROI), and debt-to-asset ratios. However, the company demonstrates strong performance in customer satisfaction, internal business processes, and learning and growth dimensions. Employing the Balanced Scorecard (BSC) framework, this research assesses these four perspectives and highlights the critical importance of the learning and growth perspective for strategic development. Through the integration of the Analytical Hierarchy Process (AHP), the study identifies the enhancement of information systems as a key strategic goal. This approach not only provides a comprehensive evaluation of PT. XYZ performance over the five-year period but also offers targeted recommendations for future business development and sustainable growth. PT XYZ overall performance is rated as good based on the Balanced Scorecard, with most indicators showing positive results, and the development of an information system is identified as a top priority to support the company's learning and growth.

Abstract

A community service program (PkM) was carried out with the aim of applying appropriate technology in the form of a corn sheller machine and strengthening the marketing capacity of harvested products through education on distribution strategies and product packaging for the Sitambiri Farmers Group. Corn is recognized as a strategic commodity suitable for cultivation in dryland areas. From the demand side, corn serves as a primary raw material in the animal feed industry, making its price relatively stable and tending to increase. The Sitambiri Farmers Group, consisting of 15 members in Lumban Dolok Village, Silaen District, Toba Regency, chose to cultivate corn as an effort to increase income. However, the use of conventional corn shellers remains a challenge due to inefficiency in time and labor, as well as poor ergonomics for farmers. This PkM activity aims to improve efficiency and production quality through the application of appropriate technology in the form of a corn sheller machine. In addition, the program provides education on marketing strategies, opens opportunities for product diversification, and encourages the improvement of farmers’ welfare. The method applied in this activity was the design of a corn sheller machine using the Axiomatic House of Quality (AHOQ). The second stage of the program focused on marketing management strategies through Focus Group Discussions (FGD) with members of the farmers group. The implementation of the corn sheller machine significantly increased capacity, reaching 17 kg per minute. The machine is more ergonomic as it reduces farmers’ workload, produces more uniform kernels with less product loss, and generates positive economic impacts. In the second-stage FGD, partners actively participated in discussions on distribution strategies, market segmentation, and the potential development of processed corn products. Active participation of the farmers group in discussions and simulations demonstrated an increase in their capacity to design marketing strategies suited to local conditions, such as online store marketing. Thus, the corn sheller machine improves efficiency and production quality, while marketing strategies strengthen the capacity and competitiveness of the farmers group.
