Performa motor bensin ditunjukan dalam data Torsi dan Daya, berbagai cara dilakukan untuk memperoleh data performa motor bensin mengukur output pada komponen crankshaft, temperatur saluran masuk dan saluran keluar ruang bakar dan temperatur lingkungan. Kegiatan penelitian bertujuan untuk memperoleh data performa pada motor bensin 4 langkah menggunakan software LabVIEW dan Data Aquisition menggunakan NI DAQ USB 6008 produk National Instrumen sebagai pengolah data. Penggunaan beberapa komponen seperti sensor putaran jenis induksi proximity, sensor temperatur dan sensor induksi tegangan tinggi, komponen penguat tegangan sensor dengan Roller Dynamometer Inertia tipe chassis. Hasil data performa motor bensin berupa Torsi dan Daya dapat terbaca pada alat uji dynamometer data Torsi mulai terbaca pada putaran 3750 RPM dengan nilai sekitar 10,65 Nm dan nilai maksimal pada putaran 7574 RPM sebesar 14,84 Nm sedangkan data Daya pada putaran 3750 sebesar 5,6 HP dan nilai maksimal pada putaran 8500 RPM dengan nilai sebesar 16,9 HP. Hasil penelitian tersebut memperlihatkan penggunaan software LabVIEW pada uji performa motor bensin tidak jauh berbeda dengan karakteristik yang dimiliki motor bensin.

Diamond-like carbon (DLC) films have attracted much attention due to their useful properties and applications. These properties are quite variable depending on film preparation techniques and conditions, DLC is a metastable state formed from highly non-equilibrium phases during the condensation of ionized particles. The nature of the films is therefore strongly dependent on their particular chemical structures. In this study, electron energy loss spectroscopy (EELS) was used to investigate how the chemical bonding configurations of DLC films vary as a function of sputtering power densities. The electrical resistivity of the films was determined, and related to their chemical structure.DLC films with a thickness of about 300Å were prepared at 0.1, 1.1, 2.1, and 10.0 watts/cm2, respectively, on NaCl substrates by d.c. magnetron sputtering. EEL spectra were obtained from diamond, graphite, and the films using a JEOL 200 CX electron microscope operating at 200 kV. A Gatan parallel EEL spectrometer and a Kevex data aquisition system were used to analyze the energy distribution of transmitted electrons. The electrical resistivity of the films was measured by the four point probe method.
