Abstract

Sistem transmisi pada kendaraan terbagi menjadi transmisi manual dan otomatis. Keduanya memiliki oli dan fungsi oli yang berbeda. Oli sepeda motor matic berfungsi melumasi mesin dan sebagai penghantar mekanisme perpindahan gigi transmisi. Penelitian ini bertujuan untuk mengetahui pengaruh kenaikan temperatur dan berapa prosentase perubahan angka viskositas oli sepeda motor matic. Telah dilakukan penelitian pengaruh temperatur terhadap angka viskositas beberapa jenis oli sepeda motor matic. Pengujian dilakukan dengan viscometer bola jatuh. Pengukuran dilakukan pada suhu 27 dan suhu 85 . Dari hasil penelitian beberapa jenis oli sepeda motor matic. Viskositas Enduro Matic SAE 10W-30 adalah 0.0346 poise, Top 1 Action Matic SAE 10W-40 adalah 0.0240 poise, BM 1 Matic SAE 10W-30 adalah 0.0240 poise, Federal Matic SAE 10W-30 adalah 0.0191 poise, Motul Scooter SAE 10W-30 adalah 0.0193 poise dan Castrol Activ Matic SAE 10W-30 adalah 0.0213 poise. Prosentase Penurunannya adalah Enduro Matic SAE 10W-30 3.26%, Top 1 Action Matic SAE 10W-40 3.02%, BM 1 Matic SAE 10W-30 3.4%, Federal Matic SAE 10W-30 3.5%, Motul Scooter SAE 10W-30 3.44% dan Castrol Activ Matic SAE 10W-30 3.2%.

Abstract

NiTi alloy is a highly functional alloy of Ni (nickel) metal and Ti (titanium) metal used for engineering. This NiTi alloy has good biocompatibility properties against human body tissues so that currently it is widely used for medical devices. This study aims to determine the effect of temperature on the tensile strength of NiTi Nanopillars and to investigate the behavior of the atoms making up NiTi nanopillars due to tensile loading. From the results obtained, the authors found the greatest value of the modulus of elasticity for the NiTi Nanopillar alloy with a temperature of 100 K, which is 80.4321 GPa. Meanwhile, the lowest modulus of elasticity is the NiTi Nanopillar alloy with a temperature of 600 K, which is 65.5847 GPa. So it can be concluded that the greater the effect of temperature on the NiTi Nanopillar alloy, the smaller the modulus of elasticity will be. This thesis also discusses the stress-strain and mechanical properties of NiTi Nanopillar alloys during the simulation process.
