Abstract
Peningkatan efisiensi mesin diesel pada kapal merupakan tuntutan dari regulasi emisi dan standar efisiensi minimum dalam EEDI sejak 2013. Disisi lain, seperlima dari total energi global digunakan untuk mengatasi rugi akibat gesekan. Gesekan juga berdampak pada kerugian mekanis pada komponen mesin seperti piston, connecting rod, camshaft, dan crankshaft. Untuk sektor perkapalan sendiri, permintaan tahunan minyak pelumas mesin adalah sebesar 1.25 juta ton. Berbagai jenis nanopartikel sering didispersikan sebagai aditif minyak pelumas untuk mengurangi gesekan dan keausan, salah satunya adalah hexagonal boron nitrida. Sejumlah penelitian telah dilakukan terkait pengaruh aditif nanopartikel hBN terhadap sifat minyak pelumas dan kinerja mesin. Pengaruh yang diteliti berupa pengaruh terhadap sifat sifat minyak pelumas, kinerja mesin, dan keausan komponen mesin. Variabel bebas penelitian ini berupa ada dan tidaknya aditif hexagonal boron nitrida pada minyak pelumas. Eksperimen berupa uji durabilitas mesin dengan metode 200 jam dari Engine Manufacture Association (EMA). Aditif hBN telah melalui tahap eksfoliasi sebelum didispersikan sebanyak 0.5% massa ke minyak pelumas dan dinilai stabil hingga 7 hari. Hasil uji durabilitas dengan penambahan aditif hBN memiliki tingkat keausan lebih rendah dengan performa yang relatif lebih baik. Pelumas setelah uji durabilitas dengan tambahan aditif hBN juga memiliki penurunan TBN lebih rendah, namun mengalami penurunan viskositas yang lebih tinggi.

Increasing the efficiency of diesel engines on ships is a demand from emission regulations and minimum efficiency standards in EEDI since 2013. On the other hand, one-fifth of the total global energy is used to overcome losses due to friction. Friction also has an impact on mechanical losses in engine components such as pistons, connecting rods, camshafts and crankshafts. For the shipping sector alone, the annual demand for engine lubricating oil is 1.25 million tons. Hexagonal boron nitride is one form of nanoparticle that is frequently added to lubricating oil as an additive to lessen wear and friction. The impact of hBN nanoparticle additions on the characteristics of lubricating oil and engine performance has been the subject of several investigations. The impact on engine performance, lubricating fluid characteristics, and component wear is what is being examined. The presence or absence of the additive hexagonal boron nitride in the lubricating oil served as the study's independent variable. The study took the form of an engine durability test utilizing the Engine Manufacture Association's 200-hour procedure (EMA). Before being dissolved up to 0.5% by mass into lubricating oil, the hBN additive underwent the exfoliation step and is thought to be stable for up to 7 days. Results of durability tests with the hBN additive applied, show a decreased rate of wear and substantially higher performance. After the durability test, lubricants that had hBN additive applied, exhibited better TBN reduction but worse viscosity reduction than without hBN additive.
