Abstract

Pada perancangan kapal, diperlukan metode untuk menganalisis hambatan kapal untuk memenuhi persyaratan kontrak dan meminimalkan biaya pengoperasian dari segi bahan bakar, biaya operasional, dan harga mesin utama. Metode yang digunakan meliputi metode empiris, computational fluid dynamic, dan eksperimen, masing-masing dengan kelebihan dan kelemahannya. Pengujian model kapal di kolam terbuka dapat menjadi solusi yang lebih murah dibandingkan dengan penggunaan fasilitas towing tank, tanpa mengurangi kualitas dan akurasi pengujian dengan melakukan koreksi akibat gaya luar seperti gerak pitch dan roll kapal. Oleh karena itu, diperlukan sistem monitoring untuk merekam pitch, roll dan wave-making kapal. Tujuan dari penelitian ini adalah merancang dan membuat sistem monitoring model kapal serta menguji dan mengolah data hasil pengujian tersebut di kolam terbuka. Komponen sistem pitch dan roll menggunakan ADXL345 dan NodeMCU ESP8266, serta komponen sistem monitoring wave-making kapal dengan konsep First Person View Camera menggunakan ESP32-CAM. Sistem monitoring pitch, roll dan wave-making kapal mampu mengirim data secara real time dengan jangkauan pengujian maksimal 25 meter dan durasi operasional 1000 menit. Pengujian model kapal dilakukan dengan 5 variasi kecepatan dan 8 kali percobaan pada setiap kecepatan. Pengolahan data pitch dan roll menggunakan metode Fast Fourier Transform dan pengolahan data wave-making kapal menggunakan metode redraw pada 3D dan 2D. Hasil pengujian menunjukkan bahwa semua sistem monitoring dapat menerima, merekam, dan mengekspor data dengan baik. First Person View Camera dapat melakukan live stream secara lancar. User interface yang dikembangkan memudahkan pengguna dalam melakukan pengujian model kapal di kolam terbuka dan mendapatkan nilai 82 atau AB (baik sekali) dari 63 responden yang mengikuti survey.

In ship design, methods are needed to analyze ship resistance to meet contract requirements and minimize operational costs in terms of fuel, operational costs, and the price of the main engine. The methods used include empirical methods, computational fluid dynamics, and experiments, each with its advantages and disadvantages. Testing ship models in open water can be a cheaper solution compared to using towing tank facilities, without compromising the quality and accuracy of the tests by correcting for external forces such as ship pitch and roll movements. Therefore, a monitoring system is needed to record the ship's pitch, roll, and wave-making. The objective of this research is to design and create a monitoring system for ship models, as well as to test and process the data from these tests in open water. The pitch and roll system components use the ADXL345 and NodeMCU ESP8266, while the wave-making monitoring system components use the First Person View Camera concept with the ESP32-CAM. The pitch, roll, and wave-making monitoring system can send data in real-time with a maximum testing range of 25 meters and an operational duration of 1000 minutes. The ship model tests were conducted with 5 variations of speed and 8 trials at each speed. The pitch and roll data were processed using the Fast Fourier Transform method, and the wave-making data were processed using the redraw method in 3D and 2D. The test results show that all monitoring systems can receive, record, and export data effectively. The First Person View Camera can live stream smoothly. The developed user interface facilitates users in testing ship models in open water and received a score of 82 or AB (very good) from 63 respondents who participated in the survey.
