Abandoned mining sites often experience a decline in soil fertility, which impacts soil quality and agricultural sustainability. This study aims to explore the potential of Pseudomonas fluorescens in rehabilitating limestone mining lands and enhancing the growth of Sengon (Falcataria moluccana) trees grown in polybag media. Sengon was selected as a pioneer species due to its resilience in degraded soils and its ability to improve soil structure. This study used an experimental design involving eight different treatments, which included the application of manure and varying concentrations of Pseudomonas fluorescens. Evaluations were conducted on the 25th and 50th days by measuring plant growth parameters such as plant height, root length, and key soil chemical properties, including pH, organic carbon, total nitrogen, total phosphorus, total potassium, and cation exchange capacity (CEC). The results showed that the application of 15 mL of Pseudomonas fluorescens on day 50 resulted in optimal plant growth, as indicated by an increase in plant height, root length, and soil quality improvement. The application of Pseudomonas fluorescens also enhanced soil pH, organic carbon, total nitrogen, and cation exchange capacity, all of which contributed to the improvement of soil fertility in the limestone mining land. This study provides evidence that Pseudomonas fluorescens can play a role in the rehabilitation of abandoned mining lands and improve the growth of Sengon trees, contributing to the recovery of degraded ecosystems.

This study was motivated by the low performance of students’ drop shot skills in elementary school badminton extracurricular activities, where the success rate of shots remained low despite regular training. The aim of this research was to analyze the effect of drop shot training using two methods—fixed targets and variable targets—on improving students’ shot accuracy. The study employed an experimental method with a pretest-posttest control group design. The sample consisted of 30 students selected through purposive sampling, with the requirement of having participated in badminton extracurricular activities for at least one year. The participants were divided into two groups: 15 students underwent fixed-target training, and 15 students underwent variable-target training. The training program was implemented over six weeks with a frequency of three sessions per week. The results indicated that both training methods significantly improved students’ drop shot accuracy. However, the variable-target training group showed greater improvement compared to the fixed-target group. This was due to the training variation, which required better concentration, adaptability, and decision-making, making it more similar to real game conditions. These findings highlight the importance of applying varied training methods in developing students’ basic badminton skills. Therefore, this study provides practical implications for coaches to prioritize variable-target training methods in coaching programs to enhance the effectiveness of technical skills, particularly the drop shot.

Conventional robotic surgical systems, while offering enhanced dexterity and 3D visualization, suffer from a critical limitation: the absence of tactile sensation. This sensory disconnect can lead to inadvertent tissue damage from excessive force application and complicates delicate maneuvers that rely on the surgeon's sense of touch. This research proposes and validates a novel surgical robotic system architecture designed to bridge this sensory gap by integrating high-fidelity 3D visual input with accurate, real-time force feedback from tactile sensors mounted on the end-effector. To rigorously evaluate this innovation, a structured comparative methodology was employed. A cohort of surgeons performed standardized surgical tasks, including suturing and tissue manipulation, on realistic soft-tissue phantoms. The performance of a conventional (visual-only) system was benchmarked against that of the proposed (visual-haptic) system. A comprehensive dataset was collected, which included objective metrics such as task completion time, precision deviation from the ideal tool path, and the magnitude of applied forces. Concurrently, subjective evaluations from the participating surgeons were gathered to assess perceived control, cognitive workload, and overall task confidence. The test data revealed statistically significant improvements when using the visual-haptic system. Participants not only completed tasks with greater speed and accuracy but also applied considerably lower and more consistent forces. The analysis underscores that haptic feedback, enabled by advanced sensor fusion, not only restores a crucial 'sense of touch' to the surgeon but also reduces the incidence of excessive force application, potentially minimizing tissue trauma and improving patient recovery. These findings confirm the hypothesis that haptic-visual integration constitutes a new paradigm in robotic surgery, shifting the paradigm from purely visual guidance to a more intuitive, multi-sensory surgical experience. This study also discusses future challenges and opportunities, including the potential for AI-driven partial autonomy, such as creating virtual safety boundaries or automating sub-tasks, and the development of next-generation sensor technologies to further enhance clinical outcomes.
