Abstract

Pendekatan, strategi, metode, dan teknik pembelajaran pada hakikatnya dapat dibedakan tetapi tidak dapat dipisahkan. Keempat istilah tersebut merupakan satu kesatuan dalam pembelajaran. Pendekatan, strategi, metode, dan teknik pembelajaran yang akan dan/atau sedang digunakan dapat diketahui dari langkah-langkah pembelajaran yang telah tersusun dan/atau sedang terjadi. Pendekatan pembelajaran adalah cara umum dalam memandang pembelajaran. Sedangkan strategi pembelajaran adalah ilmu dan kiat di dalam memanfaatkan segala sumber belajar yang dimiliki dan/atau yang dapat dikerahkan untuk mencapai tujuan pembelajaran yang telah ditetapkan. Metode mengajar adalah berbagai cara kerja yang bersifat relatif umum yang sesuai untuk mencapai tujuan pembelajaran tertentu dan teknik pembelajaran adalah ragam khas penerapan suatu metode sesuai dengan latar penerapan tertentu. Teknik pembelajaran mengambarkan langkah-langkah penggunaan metode mengajar yang sifatnya lebih operasional. Faktor-faktor yang perlu diperhatikan dalam penentuan teknik pembelajaran di antaranya adalah kemampuan dan kebiasaan guru, ketersedian sarana dan waktu, serta kesiapan siswa. Faktor-faktor yang perlu dipertimbangkan dalam memilih strategi pembelajaran ialah tujuan pembelajaran, jenis dan tingkat kesulitan materi pelajaran, sarana, waktu yang tersedia, siswa, dan guru.

Abstract

This study aims to analyze antennas' characteristics at a frequency of 2.2 GHz, including the value of return loss, VSWR, gain, bandwidth, surface current, and radiation pattern. The antenna characteristics have been designed using simulations made with FR-4 substrates with a dielectric constant ε_r= 4.3 and substrate thickness (h) = 1.6 mm and copper patches with a patch thickness of 0.035 mm. Single antennas are made first to get the desired parameters, then continue to make 1x2 and 1x4 antenna arrays. The feeding antenna array is arranged using the Wilkinson power divider technique on the side of the patch. Antenna array planning aims to increase the antenna gain value as well as the antenna directivity value. From the simulation results, successive values were obtained starting from a single antenna, a 1x2 antenna array, and a 1x4 antenna array which included return loss of -22 dB, 25.9 dB, and -15.3 dB. Swr values are 1.1,1.1,1,1.4 each. The gain values are 3.38 dB, 5.52 dB, 7.84 dB, respectively. Antenna bandwidth is obtained by 100 MHz, 400 MHz, and 200MHz. The angular width obtained is 99.40, 92.20, and 80.20.

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
