Abstract

ROV (Remotely Operated Vehicle) is a product of technological development, functioning to perform tasks in the water. Big tasks such as coral reef exploration, oil refineries, underwater monitoring, and sea accident rescue are carried out by such technology. ROV or unmanned submarines have 6 degrees of freedom, but for diving it requires only 3 movements, that is, surge, heave, and pitch motions. In its operation, the ROV requires a navigation system in the form of estimation of the ROV position under diving conditions. In this study, two methods were used to estimate the ROV position under diving conditions, that is, the H-infinity method and the Ensemble Kalman Filter (EnKF). Both methods proved reliable on other platforms. The simulation results in this study showed that the EnKF method was more accurate than the H-Infinity method. The H-Infinity method had an accuracy of around 87%, while the EnKF method reached an accurate of 99 %.

Abstract

Underwater exploration activities always have their own charm, many exotic objects that exist in underwater ecosystems have not been mapped properly, due to the lack of related databases of the shapes and names of these underwater objects. Another factor that affects the visibility of objects related to the quantity of light intensity that enters under water, also not as much above the surface of the abundant water, especially during the day. This also hinders the process of documenting underwater objects. The main purpose of this study was to obtain the shape of underwater objects for several conditions of light intensity under water using a low cost digital image sensor camera. The method used in this research is to combine tonal distributions with object edge detection in digital image processing. The test results show that object detection tests in clear and turbid water can detect objects even though they are using a low-cost and low-resolution camera, but with the help of adequate lighting it can be done. From that it can be concluded that the detection of underwater objects is successful.

Abstract

Fish farming in Indonesia has significant potential, both for consumption and ornamental purposes. However, one of the main challenges in fish farming is the manual feeding process, which is time-consuming and requires considerable labor. To address this issue, this research develops an automated fish feeding device based on the Internet of Things (IoT). This study aims to design and test an automatic fish feeding device that uses the ESP32 microcontroller connected to IoT. The system allows for automatic and controlled feeding, based on time settings and the required amount of feed. The methods employed in this research include the design of hardware and software integrated with IoT sensors, which can be programmed to dispense feed at specific distances and times. Testing was conducted to measure feed dispensing distance, energy efficiency, and labor cost savings. The test results indicate that the device is capable of dispensing feed up to a distance of 5 meters, with feed particle sizes ranging from 4-5 mm and the motor running at 12,000 rpm. The system also utilizes solar panels as an energy source, reducing dependence on electricity. The findings of this study demonstrate that the IoT-based automatic feeding device can enhance operational efficiency, reduce labor costs, and decrease electricity consumption, making it an innovative solution suitable for the fish farming industry in Indonesia.
