Abstract

Coastal areas are vital areas for fishing activities, and the weather in this area plays a very important role in the safety and efficiency of fishermen's operations. Fishermen on the coast often face the challenges of weather that is changeable and can be very extreme, including strong winds that can cause high waves and unsafe sea conditions. Therefore, the development of a Google spreadsheet-based weather monitoring system for fishermen in coastal areas is very relevant and strategic to support safer and more productive fishing activities. This research aims to make it easier for fishermen to monitor the weather in coastal areas in real time. Testing is carried out by running the system for observation for a predetermined time duration. This research uses an anemometer, DHT11 and raindrop sensors connected to a NodeMCU ESP32 microcontroller to send data to a Google spreadsheet, with readings of wind speed, temperature, air humidity and rain values. This research was carried out at the Nusantara Prigi fishing port, Trenggalek, challenging the work of anemometer sensors, DHT11 and raindrop sensors. Testing of tools and data obtained by comparing data on wind speed, temperature and air humidity using a digital anemometer and digital thermometer hygrometer humidity. The results of this research are that a Google spreadsheet-based weather monitoring design for fishermen in coastal areas can monitor wind speed, air humidity, temperature and detect rain online using a spreadsheet application and functions well with an average error accuracy of 3%.

Abstract

This research aims to design and develop a smoke level detection device based on NodeMCU ESP32 with a room-scale ratio of 1:10. The issue at hand is the occurrence of two false alarms during sailing practices on the MT. SUPREME STAR due to the oversight of the galley Exhaust Fan activation by the cook, resulting in kitchen smoke escaping the room. The designed device is equipped with 4 MQ-135 sensors and an LCD, along with 4 ACS712 sensors to measure the smoke density in the galley in terms of ppm (Part Per Million). LED serves as a parameter for CO (Carbon Monoxide), and ACS712 is utilized to detect mA, determining whether the sensor can activate the Exhaust Fan, indicated by the detected mA. This research includes designing a device to detect smoke levels and automatically activate the Exhaust Fan, as well as understanding the operation of smoke sensors and the NodeMCU ESP32 Microcontroller. By using the "trial and error" research method, namely a series of experiments carried out repeatedly using different methods and materials. Test results indicate that the MQ-135 sensor has an average error ranging from -7.5% to +5.69%, influenced by input voltage. Additionally, IoT test results show that some sensors face difficulty in transmitting data due to voltage drop when Wi-Fi is enabLED. Overall system testing demonstrates that the device effectively controls smoke in the galley. The Exhaust Fan operates according to the predetermined program, and the LED provides an indicator of smoke opacity in accordance with the Air Pollution Standard Index. The MQ-135 sensor can prevent smoke emissions by automatically activating the Exhaust Fan when smoke levels are detected above 30 ppm. Thus, this device prototype can be a solution to address false alarm incidents, and its success indicates the potential use of MQ-135 sensors in the automation of smoke control systems in enclosed spaces.

Abstract

As an important means of sea transportation for the distribution of goods and human mobility between islands, ships require a reliable prime mover to avoid wear or damage, especially when overspeeding occurs which can result in fire. Therefore, a prototype was created that uses an IR Obstacle sensor to monitor the RPM speed of the rotating engine. By using Arduino Uno as a processor, this prototype is able to display the RPM value on the LCD and provide a signal in the form of a green light if the speed is below 4000 Rpm, as well as a red light and buzzer sound if overspeed occurs above 4000 Rpm, followed by the engine turning off after 15 seconds. Testing shows that this prototype has a high level of accuracy, with a difference between 0.08% to 2.73% and an average difference of 1.003%.

Abstract

The shipping industry faces challenges in reducing environmental impact and increasing operational efficiency. Among them are the expansion tanks on ship engines which play an important role in maintaining the pressure and water quality of the engine cooling system, which is still run manually on some ships. This can result in the risk of engine damage due to overheating or unstable pressure. Manual water filling that requires crew supervision can cause operational instability. This research designed a prototype of an automatic water filling system for expansion tanks, using microcontroller-based automation technology and an Internet of things system to make monitoring easier. This system aims to increase efficiency and reduce the risk of engine damage, thereby supporting the sustainability of ship operations in the future. In the trials that have been carried out, this tool is able to operate the expansion tank filling automatically and efficiently. The distance sensor used has high accuracy with a largest error of 1.6%, and an average error of 0.01%. Integration with the Internet of Things system can run well and reliably with 100% success and latency of 0.5 – 1 second. The system's overall success rate is 80%. So the system can be used in real working conditions

Abstract

Electrical energy is distributed using copper cables as an intermediary, from high to low voltage systems, until it is ready for use. Copper cables were chosen to transfer electrical energy because the material is able to conduct electrons that can move freely. In this research the author used a research methodology type of method. This research used the ADDIE type Research and Development (R&D) method. Addie consists of Analysis, Design, Development, Implementation and Evaluation. Several test subjects were carried out on light bulbs, 18 W and 36 W AC TL lamps, 60 W AC incandescent lamps, and 8 W AC LED lamps. It was obtained that lamps that could emit light efficiently were TL lamps because TL lamps can operate at high frequencies. Generated by Tesla Coil. From the calculation of the ship's generator fuel, if all the lights use Tesla coils in MT. Long ship, fuel cost savings to Rp. 3,528,263 which should be Rp. 16,691,589 to Rp. 13,163,325. The research results stated that it had not reached the expected value because the ones that could work efficiently were TL lamps because the Tesla coil was only able to work on lamps that had winding components.

Abstract

The shipping industry is closely related to economic growth in various countries. This transportation is very dependent on export and import activities. As the country's economy improves, especially in Asia, the maritime transportation business in Indonesia will also develop. The pattern of sending goods via sea transportation has changed, especially in terms of bulk transportation. which demands modern technology such as automation and intelligent control systems. This research aims to design and develop Android-based spreader control using Arduino Mega 2560 on a floating ship. This project is designed to increase efficiency and ease of operation in the loading and unloading process on ships, which previously still used manual control with a remote control or joystick which had limitations such as limited visibility. In this research, the spreader control system is connected to an Arduino Mega 2560 microcontroller via the HC-05 Bluetooth module, allowing the operator to control the spreader via an Android device. Test results show that data is obtained at a distance of 1 to 13 meters, the Android-based spreader control system shows a response time ranging from 1 to 9 seconds, which shows that the system is functioning properly. At a distance of 14 to 19 meters, the response time increases to 18 seconds, indicating quite good system performance. This shows that there is quite significant latency in data transmission. However, the system still managed to carry out spreader control well. At 20 meters, the system failed to respond to the spreader control. This shows that the effective range of this Bluetooth module is below 15 meters. This research makes a significant contribution to the development of automatic control technology in the shipping industry, especially in the use of intelligent control systems integrated with mobile devices.
