Abstract

Denpasar as a rapidly growing city needs good traffic (road ways, bridges and traffic lights) inventory. However, in actual fact, at present the government agents in charge are still using graphical data in the form of maps and manual information data (blueprints and paper) which results in various problems. Some of the problems include problems in data storage since the map and information data available at present are saved using paper media which would not last very long and easily damaged, problems in planning the maintenance of road ways, bridges and traffic lights because of the relatively long time spent to check the condition, last maintenance time, and associating acquired data with the maps, which could take half a day (according to the amount of data searched) since the checking of data is done manually and separately (disintegrated) from the information data in the maps. Furthermore, manual data checking has a low level of accuracy, since there could be data skipped in the checking process. To overcome the problem of traffic inventory (road ways, bridges and traffic lights) in Denpasar, a GIS-based System (Geographical Information System) is designed and made in this final project, which could deliver information on road ways, bridges and traffic lights in Denpasar in detail. This system would give solutions to the problems such as digital (softcopy) and integrated map data and information data storage so that the map data will last longer and not easily damaged (not including the condition of force majeure), decision making in planning the maintenance of road ways, bridges and traffic lights could be made faster since the checking of the condition, last maintenance time and map marking is done by the system to the integrated data and takes just a few seconds to complete. Moreover, data checking done by the system will have relatively high accuracy, as there would be no data skipped in the checking process

Abstract

This research focuses on designing an Internet of Things (IoT)-based control system for multiple servo motors. The system is equipped with an Android-based controller using a virtual joystick, enabling online and real-time control. The use of a virtual joystick on an Android smartphone application allows operators to control the device remotely, enhancing safety and work efficiency, especially in hazardous or hard-to-reach areas. The objective of this research is to evaluate the success and accuracy of servo movements to ensure optimal performance. The findings aim to demonstrate that IoT technology can serve as a reference for implementing wireless control in various automated systems, improving operational quality in different applications. Experimental results show that joystick control via an Android device facilitates online operation and can be effectively utilized. However, hardware limitations, such as servo motors and brackets, reduce the accuracy of object transfer, leading to failure in some trials, with a success rate of 70 percent. Nevertheless, this research can serve as a reference for future developments in the field, particularly in enhancing the accuracy and stability of IoT-based control systems.

Abstract

Identifying and characterizing blood cells are vital for diagnosing diseases and evaluating a patient's health. Blood, consisting of plasma and cells, offers valuable insights through its biochemical and ecological features. Plasma constitutes the liquid component containing water, protein, and salt, while platelets, red blood cells (RBCs), and white blood cells (WBCs) form the solid portion. Due to diverse cell characteristics and data complexity, achieving reliable and precise cell detection remains a significant challenge. This study presents a network reduction strategy and deep ensemble learning approaches to detect blood cell types based on the YOLOv8 model. Our proposed methods aim to optimize the YOLOv8 model by reducing network depth while preserving performance and leveraging deep ensemble learning to enhance model accuracy. Based on the experiments, the NRS strategy can reduce the complexity of the YOLO model by reducing the depth and width of the YOLO network while maintaining model performance by 4%, outperforming the baseline YOLOv8 model.
