Abstract
Seiring dengan pertumbuhan ekonomi yang terus meningkat, permintaan akan jasa ekspedisi yang lebih baik pun semakin meningkat untuk memenuhi jumlah permintaan pengiriman barang. Emisi gas buang kapal menimbulkan ancaman bagi lingkungan seiring dengan lalu lintas laut yang padat. Port State Control (PSC) sebagai pengawas kepatuhan kapal asing terhadap konvensi internasional, tetapi dalam pelaksanaannya PSC membutuhkan waktu lama dan risiko yang besar khususnya berhubungan dengan emisi gas buang kapal. Oleh karena itu, penelitian ini penting untuk dilakukan agar dapat membantu pelaksanaan tanggung jawab dari PSC. Metode yang digunakan dalam penelitian ini diantaranya : Computational Fluid Dynamics untuk mensimulasikan emisi gas buang kapal, Additive Manufacturing untuk memanufaktur customize parts, eksperimen untuk menganalisa pengaruh jarak terhadap pengukuran emisi NOx, metode sniffing dalam pengambilan data emisi NOx tepat di ujung cerobong gas buang kapal, rekayasa terbalik untuk membuat 3D desain drone, interpolasi dalam mencari nilai properti exhaust gas, dan galat persentase untuk mengetahui error dalam pengolahan data hasil pengukuran emisi NOx menggunakan drone. Setelah dilakukan eksperimen pengaruh jarak terhadap pengukuran emisi NOx didapatkan hasil bahwa nilai emisi NOx berbanding terbalik dengan jarak pengukuran sensor, sedangkan juga didapatkan temuan bahwa exhaust stack horizontal memiliki effective stack height tepat di titik pusat outlet dari exhaust stack tersebut. Hasil simulasi numerik menunjukkan bahwa jarak aman drone dari cerobong asap yaitu ±0,5 m saat mengukur emisi NOx, mengacu pada suhu operasi 3M Polymide Film Tape 5413. Drone dapat dipakai untuk mengukur emisi NOx pada cerobong gas buang kapal karena hanya memiliki error 4,5% pada saat engine posisi idle dengan jarak pengukuran 0,5 m dan error 4,6% pada saat engine posisi operasi dengan jarak pengukuran 2 m dalam mengolah data menggunakan Gaussian Dispersion Equation untuk mengetahui nilai emisi pada jarak 0 m dari ujung cerobong yang dibandingkan dengan pengukuran aktual pada jarak 0 m.

Along with economic growth that continues to increase, the demand for better shipping services is also increasing to meet the number of requests for shipping goods. Ship exhaust emissions pose a threat to the environment along with heavy marine traffic. Port State Control (PSC) as a supervisor of compliance of foreign ships to international conventions, but in its implementation PSC takes a long time and is a big risk, especially related to ship exhaust emissions. Therefore, it is important to conduct this research in order to assist the implementation of the responsibilities of the PSC. The methods used in this study include: Computational Fluid Dynamics to simulate ship exhaust emissions, Additive Manufacturing to manufacture customized parts, experiments to analyze the effect of distance on NOx emission measurements, sniffing method in collecting NOx emission data right at the end of the ship's exhaust chimney, reverse engineering to make 3D drone designs, interpolation in finding exhaust gas property values, and percentage errors to find out errors in processing NOx emission measurement data using drones. After experimenting with the effect of distance on NOx emission measurements, the results show that the NOx emission value is inversely proportional to the sensor measurement distance, while it is also found that the horizontal exhaust stack has an effective stack height right at the outlet center of the exhaust stack. The numerical simulation results show that the drone's safe distance from the chimney is ±0,5 m when measuring NOx emission, referring to the operating temperature of 3M Polymide Film Tape 5413. Drones can be used to measure NOx emission in ship exhaust chimneys because they only have an error of 4,5% when the engine is in the idle position with a measurement distance of 0,5 m and an error of 4,6% when the engine is in the operating position with a measurement distance of 2 m in processing data using Gaussian Dispersion Equation to determine the emission value at a distance of 0 m from the tip of the chimney being compared with actual measurements at a distance of 0 m.
