Abstract

Trademark infringement detection is essential to prevent consumer confusion, particularly in the digital era where visually similar logos are widespread. This study proposes a similarity threshold determination framework using Siamese Neural Networks (SNN) combined with Bayesian Optimization to improve the accuracy of trademark similarity assessment. Logo images were collected from the Indonesian intellectual property database, preprocessed into a uniform format, and trained using a triplet loss approach. Bayesian Optimization was applied to determine the optimal similarity threshold, minimizing false positive and false negative classifications. The proposed model achieved an accuracy of 92.23%, with precision of 93.34%, recall of 91.44%, and an F1-score of 92.39%. The optimal threshold (0.200149) effectively balanced sensitivity and specificity, resulting in low misclassification rates. These findings demonstrate that integrating SNN with Bayesian Optimization provides a robust and legally relevant framework for trademark infringement detection, offering practical implications for strengthening intellectual property protection.

Abstract

Entrepreneurship courses can become overly centered on concepts and business plans when students have limited contact with customers and market uncertainty. This article describes the implementation of a practice-based entrepreneurship training program for 24 students at Universitas Sugeng Hartono from May 14 to June 25, 2026. The program combined entrepreneurial-mindset orientation, business proposal development, preparation of marketing materials, direct market practice, weekly progress reporting, mentoring, and final reflection. A descriptive qualitative approach was used to organize evidence from proposals, progress reports, classroom observations, supporting documentation, and student reflections. The implementation produced a structured learning sequence that moved from opportunity identification to customer contact, feedback, and strategy revision. Market validation and minimum viable product concepts gave students a practical basis for testing assumptions before expanding a business idea. Weekly reports made activity, obstacles, and follow-up decisions visible, while mentoring sessions converted individual difficulties into shared problem-solving material. Because participant records were heterogeneous and did not provide a complete standardized outcome dataset, the program cannot support claims about causal effects, average revenue gains, or changes in entrepreneurial intention. Its contribution is an implementable model for connecting entrepreneurship concepts with customer-facing action and reflective mentoring. Future delivery should retain the practice cycle while adding common indicators, baseline and endline measures, and systematic reflection records

Abstract

E-waste has become a critical global issue due to the rapid growth of electronic product consumption and the environmental risks associated with improper disposal. Traditional disposal methods, such as landfilling and incineration, are no longer sustainable as they lead to environmental degradation, health hazards, and loss of valuable resources. In contrast, remanufacturing, a key component of the circular economy, offers a more sustainable solution. This study explores the effectiveness of remanufacturing as a strategy for e-waste management, focusing on its ability to reduce waste generation and improve material efficiency in the electronics industry. The research utilizes a case study approach, examining industrial-scale remanufacturing processes, including material input-output analysis to track resource flows and waste streams. The findings reveal a significant reduction in e-waste generation, with up to a 50% decrease in waste volume, and substantial improvements in material recovery, particularly in metals like gold and copper. Additionally, the study highlights the economic and environmental benefits of remanufacturing, such as cost savings and resource conservation. However, the study also identifies barriers to the widespread adoption of remanufacturing, including technological, financial, and regulatory challenges. The results underscore the potential of a circular-economy-based remanufacturing model as a sustainable solution for the electronics industry. The study calls for further research into improving remanufacturing technologies, enhancing policy frameworks, and expanding circular economy practices across various industries.

Abstract

Introduction: Achieving carbon neutrality in industrial systems is essential for mitigating climate change and promoting sustainability. The increasing demand for energy optimization and carbon emission reduction has driven the development of advanced technologies, particularly hybrid machine learning (ML) models. These models, combining ensemble learning and reinforcement learning (RL), offer significant promise in optimizing industrial processes, reducing energy consumption, and improving environmental performance. This study explores the application of hybrid ML models in achieving carbon neutral goals through dynamic process optimization and energy control in industrial settings. Literature Review: Hybrid ML models integrate different machine learning techniques to handle complex and dynamic environments effectively. Ensemble learning methods, such as boosting, bagging, and stacking, combine multiple algorithms to improve predictive performance and robustness. Reinforcement learning (RL), on the other hand, enables real time decision making and adaptation based on trial and error interactions with the environment. In energy optimization, these models are used to reduce energy intensity and carbon emissions, enhancing overall operational efficiency. Previous studies have demonstrated the effectiveness of ML models in energy management, but challenges such as data quality, model integration, and computational complexity remain. Materials and Method: The study applies hybrid ML models combining ensemble learning and RL to optimize energy consumption and minimize carbon emissions in industrial processes. Data from real time sensors and operational parameters are used to train the models. The ensemble learning component improves the accuracy of energy predictions, while RL ensures dynamic process adjustments in response to fluctuating energy demand. The models were tested in various industrial settings, including manufacturing processes, smart grids, and microgrid systems. Performance metrics such as energy efficiency, carbon emissions reduction, and operational costs were evaluated to assess the effectiveness of the models.  Results and Discussion: The hybrid ML models achieved significant reductions in energy intensity (15-20%) and carbon emissions (18-25%). The real time adaptability of the RL component allowed the models to adjust energy consumption patterns dynamically, improving energy efficiency and reducing waste. The models demonstrated their ability to adapt to varying operational conditions, ensuring optimal energy use. A cost-benefit analysis showed that the hybrid models provided substantial energy savings and reduced operational costs, with a return on investment (ROI) of 30-35% within the first year of deployment. However, challenges such as computational complexity and data quality issues were identified, highlighting the need for further refinement in model development.

Abstract

The rapid development of modern manufacturing technology has driven the emergence of human-robot collaboration (HRC) as part of the transformation toward a human-centric intelligent production system. In collaborative work environments, robots are not only required to work efficiently but also to interact safely and responsively with operators. However, most conventional industrial robot systems still use rigid motion controls and are unable to dynamically adapt to human activity around them.This research aims to develop a human-robot collaboration system by integrating computer vision technology to detect operator movement and applying adaptive control algorithms to the robot manipulator. The research methodology includes designing a collaborative workstation, implementing a computer vision-based motion detection system, developing an adaptive control algorithm, and evaluating system performance through various experimental scenarios. Evaluation parameters include task completion time, safe distance, and system response time.The results show that the developed system significantly improves the efficiency and safety of human-robot interaction compared to conventional systems, with shorter task times, optimal safe distances, and faster system response to operator movements.
