Abstract

The growing demand for precision in agricultural robotics, particularly in competitive environments, has driven the development of advanced gripper mechanisms capable of efficient and accurate rice planting. This study presents the optimization of sensor-enhanced gripper mechanisms designed specifically for precision rice planting in robotic contest applications. The gripper integrates force sensors, proximity sensors, and high-resolution visual sensors, allowing for real-time feedback and adaptive control during the planting process. The system was tested both in laboratory simulations and real-world field conditions, with a focus on achieving high planting accuracy, reducing seedling damage, and enhancing overall operational efficiency. The implementation of Proportional-Integral-Derivative (PID) control and advanced image processing algorithms, such as Convolutional Neural Networks (CNN), allowed the gripper to perform with superior precision in dynamic environments typical of robotic contests. Experimental results demonstrated significant improvements in planting depth accuracy, seedling survival rates, and operational speed compared to traditional methods, highlighting the system’s potential for both competitive and practical agricultural applications. This research contributes to the ongoing development of robotic systems in agriculture and provides a robust framework for the deployment of precision planting technologies in competitive settings.

Abstract

Baby incubator is a tool for maintaining the warmth of the baby after birth so they are able to adapt with external environment. The main feature of incubator is setup room temperature for maintaining baby’s temperature to avoid hypothermia. However, for premature babies it is not only strict temperature regulation, but also many procedures, such as monitoring their body weight regularly as the indicators to determine the development of baby’s health. Baby incubator with temperature and baby weight control system is needed to make it easier for paramedics to monitoring the baby’s progress while in the incubator. System design of incubator is designed with the room temperature controller ON-OFF system in the range of 30oC – 35oC and wight scale system in the range of 0 kg – 5 kg. Incubator box will be installed using blower 12VDC and heater driver. Temperature and weight controller system is designed using BASCOM-AVR software. This research is hoped that this simple incubator design can be applied to small-scale baby health centers, such as baby clinics and community health centers.

Abstract

The goal of this research is to build and create a prototype tool capable of monitoring soil pH automatically by employing Internet of Things (IoT) technology using NodeMCU ESP8266 at UPT Palawija Tanjung Selamat. The challenge is in the limited time and effort required for manual soil pH measurement, which can impede the process of routinely checking soil quality. The technique uses a pH sensor coupled with a NodeMCU ESP8266 to wirelessly send data to an Internet of Things platform. The instrument will be built to be able to provide data in real time to the monitoring system and measure the pH of the soil on a regular basis. To guarantee the precision of the test results in this instance, the pH sensor will be meticulously calibrated. The ultimate product of this prototype design is anticipated to be a device that can continuously monitor the pH of soil without requiring direct input from land managers or farmers. It is anticipated that this instrument would offer precise and trustworthy data regarding the degree of soil acidity at the site under remote observation. Therefore, it is anticipated to improve soil management's efficacy and efficiency and allow for prompt remedial action in the event that data collection warrants it.

Abstract

In the medical field, image analysis is essential for diagnosis and patient care planning. This study compares two edge detection methods: the Laplacian of Gaussian (LoG) filter and the Chebyshev filter. The LoG filter combines Gaussian smoothing with the Laplacian operator for noise reduction and smooth edge detection, while the Chebyshev filter, known for sharp edges, allows for adjustable frequency response but is more sensitive to noise. Medical images were pre-processed to reduce artifacts and noise before applying each filter. The performance metrics, including PSNR, SSIM, and EPI, were used to evaluate the results. The Chebyshev filter achieved the highest PSNR of 20.2202 and SSIM of 0.48089 for Meningioma with a low-pass filter of order 2. The LoG filter's highest PSNR was 12.5731 and SSIM was 0.99876 for Meningioma at sigma 0.5. The highest EPI for the Chebyshev filter was 0.13067 for Pituitary with a low-pass filter of order 2, compared to the LoG filter's highest EPI of 0.39688 for Glioma at sigma 1.5. These results guide the selection of edge detection methods, enhance diagnostic accuracy and patient care planning, and contribute to advanced medical image processing technologies.

Abstract

The use of information technology at KSPPS RAYA BANDA MADANI, particularly through the Raya Mobile Information System (SIRAMO), is essential to support operations and member services. However, a thorough audit is required to ensure the security, reliability and compliance of the system to IT governance standards such as COBIT 5. This research aims to assess these aspects through an audit using COBIT 5, as well as provide recommendations for improvement.This research uses a case study method with a qualitative approach. Data was collected through interviews, questionnaires, observation, and document analysis. The results showed weaknesses in data security, information accuracy, and compliance with COBIT 5 standards, although SIRAMO supports mobile operations effectively. Recommendations for improvement include enhancing security controls, validating data, and developing more effective monitoring mechanisms. The result of this study is that audits using COBIT 5 can identify areas that need improvement to enhance the performance and security of SIRAMO at KSPPS RAYA BANDA MADANI, as well as improve operational efficiency and member satisfaction.
