“…As the viscosity of oil changes with temperature viscosity of selected lubricating oil should be matched with the operating temperature of the system. [9][10][11] Thus to use a vegetable oil like gear oil, hydraulic oil, or engine oil its viscosity should be improved to compatible with the application. [12][13][14] Generally, polymers as polyethylene, poly (alkyl methacrylate), poly (isobutylene) are used as viscosity modifiers (to control change in viscosity with temperature) of mineral-based lubricating oils.…”

Biodegradable vegetable oil-based lubricating oil is a better auxiliary for mineral-based lubricants as their viscosity index, flash point, lubricity is high. Nonetheless, their limited viscosity range is a major constraint of their usage as lubricating oil. Polymers have proven their capability of increasing the viscosity of vegetable oils without adversely affecting their lubricating properties. Potentially of use of oxidized polyethylene (OPE) as a viscosity booster of palm oil to use as a lubricating oil is studied adding several weight percentages of OPE to the palm oil independently. The addition of 1.75 wt% of OPE to the palm oil resulted in a blend with comparable kinematic viscosity to H68 and the addition of 2.0 wt% of OPE to the palm oil resulted in a blend with comparable kinematic viscosity to SAE30. Palm oil behaves as Newtonian fluid at low temperatures and as the temperature increases, it behaves as shear thickening fluid while the addition of OPE cause to shear thinning behavior.

“…The metal additives usually utilized in engine oils act as an anti-wear or friction reduction media [16] where each element has its heat capacity. Therefore, these metals are also required to consider since the presence of these elements may cause an unexpected effect on the engine oil's heat capacity and viscosity.…”

This study aims to determine the dominant chemical elements that may improve the monitoring of the productivity and efficiency of heavy engines in 2015-2021 in the company. The method used is usually Scheduled Oil Sampling. This article proposes a new approach. The research problems are analyzing the recorded chemical elements that are produced by heavy engines and visualizing them through the Tableau program. The basic design of the study is learning the given data after visualization and using the Principal Component Analysis. This method is to obtain chemical elements that affect engine wear during each engine's use in the 2015-2021 period. Because there are three categories in each element in the oil sample, namely wear metals, contaminants, and oil additives, a technique is needed to obtain these elements using Principal Component Analysis. Therefore, Oil Sampling Analysis through data exploration using Tableau resulted in a new approach to data analysis of elements recorded by heavy vehicles. The main findings as a result of the analysis are given by the visualization of Tableau, in which there are five machines analyzed to obtain the main components that cause engine wear. From the visualization results, it is shown that there is one engine coded MSD 012 that experienced wear and tear in 2018 and 2019. This shows where two main components, Ca and Mg, dominate engine wear. These results have been confirmed with the related companies. The company then carried out further studies on the machine to get special treatment because of these results.

Validasi Metoda Pengujian Kandungan Kalsium, Magnesium, Dan Seng Dalam Pelumas Dengan Spektrometri Serapan Atom (Ssa) Menggunakan Teknik Pelarutan Langsung Oleh Xilena

<p class="Abstrack">Pengujian kandungan unsur logam kalsium, magnesium, dan seng di dalam minyak pelumas menggunakan spektrometri serapan atom dengan teknik pelarutan langsung oleh xilena telah dilakukan. Kandungan unsur logam tertentu (seperti: kalsium, magnesium, dan seng) merupakan salah satu parameter syarat mutu SNI wajib pelumas yang harus dipenuhi. Menurut SNI, terdapat dua pilihan metode uji yang dapat dijadikan acuan untuk melaksanakan pengujian kandungan unsur logam dalam minyak pelumas, yaitu dengan menggunakan ICP-AES atau AAS. Pada penelitian ini contoh minyak pelumas dilarutkan secara langsung dengan xilena, kemudian dilakukan pengukuran dengan AAS. Penggunaan teknik persiapan contoh dengan pelarutan secara langsung menggunakan xilena, diharapkan dapat menyederhanakan proses pengujian dibandingkan dengan menggunakan cara pelarutan asam. Hasil pengukuran pada percobaan yang dilakukan menunjukkan bahwa, linearitas kurva kalibrasi (R<sup>2</sup>) untuk Ca = 0,99640; Mg = 0,99968; dan Zn = 0,99938; dengan nilai presisi untuk Ca = 2,168 (%RSD) < 3,914 (0.67*CV-Horwitz); Mg = 1,265 < 5,670; dan Zn = 0,665 < 4,736; %rekoveri Ca = 101%, Mg = 98%, Zn = 98%; batas deteksi (LoD): Ca = 0,013 mg/L; Mg = 0,002 mg/L; dan Zn = 0,014 mg/L; dan nilai LoQ: Ca = 0,043 mg/L; Mg = 0,007 mg/L; dan Zn = 0,048 mg/L. Parameter validasi (linearitas, presisi, akurasi, batas deteksi, dan batas kuantifikasi) yang diperoleh dari hasil pengujian ini relative dapat diterima. Proses persiapan larutan untuk pengujian dengan AAS dengan menggunakan xilena jauh lebih cepat dan sederhanan dibandingkan dengan pelarutan menggunakan asam.</p><div><div><p> </p><p> </p></div></div>
