Abstract

Mahasiswa S1 Pendidikan Teknik Otomotif, Pendidikan Teknik Mesin, dan Teknik Mesin memiliki minat dan bakat dalam servis sepeda motor. Tujuan pengabdian ini adalah untuk melakukan servis sepeda motor mahasiswa dan masyarakat sekitar UNNES. Metode pengabdian ini yaitu persiapan, pelaksanaan, dan evaluasi. Tahap persiapan dimulai dengan pendataan mahasiswa yang ingin menjadi teknisi, kemudian pelatihan teknisi, dan penyiapan alat dan bahan di lokasi servis sepeda motor. Tahap pelaksanaan dilakukan berupa praktik langsung servis berkala. Tahap evaluasi dilakukan untuk mengetahui apakah ada keluhan dari customer setelah sepeda motornya di servis. Hasil pengabdian menunjukan bahwa servis gratis sepeda motor yang diadakan di Halaman Masjid Ulul Al Bab tanggal 7-8 Mei 2024 berjalan lancar. Total ada 264 unit sepeda motor yang diservis. Customer tidak mengeluhkan sepeda motornya setelah diservis yang artinya customer merasa puas.

Abstract

A crucial global issue is the world's dependence on fossil fuels as its primary energy source. An alternative solution to this problem is to use fuels such as ethanol. Using ethanol as fuel requires comprehensive optimization of the vehicle system, including the engine's temperature control. This research aims to determine the effect of engine operating temperature variations on fuel efficiency thru 4 engine temperature variations: 70, 80, 90, and 100 degrees Celsius, using two approaches: static and dynamic. The test results show that engine temperature affects fuel consumption and engine operating stability. Based on the experiments conducted, it was concluded that a temperature of 90°C is the most optimal working temperature, with an increase of 9.91% in static testing and 14.74% in dynamic testing (compared to the temperature with the lowest efficiency). It can be concluded that 90°C is recommended as the optimal working temperature for ethanol engines in the development of energy-efficient vehicles.
