Publisher : Universitas Mercu Buana

Final Gear terdiri dari pinion gear dan ring gear, yang terletak di dalam differential atau gardan. Terdapat hubungan antara final gear pada pinion gear dengan efisiensi daya / power engine kendaraan atau truck. Daya/Power Engine pada truck dinyatakan dalam satuan hp dimana Power yang dibutuhkan kendaraan di pengaruhi oleh daya tahanan gelinding, daya tahanan udara, daya tahanan kelandaian, daya energi kinetis dan daya internal engine. Awal penelitian dimulai dengan pemilihan jenis pinion gear baik dari sisi harga, material, jumlah gigi, suku cadang dan kesesuaian dengan pasangannya. Dari hasil pemilihan tersebut ada 2 jenis dari 3 jenis pinion gear yang ada di pasaran dan 2 jenis tersebut menjadi sample penelitian. Yaitu jenis pinion gear dengan jumlah gigi 11 dan jumlah gigi 12. Sedangkan pasangannya yaitu ring gear dengan jumlah gigi 37. Dalam penelitian efisiensi power engine truck kapasitas 30 ton ini dikondisikan dengan 3 variasi grade jalan ( 4%, 6% dan 8%) dalam 3 kali pengujian. Dari hasil pengujian tersebut diperoleh hasil bahwa gigi pinion dengan jumlah 11 memiliki efisiensi power engine 68,5 %, sedangkan untuk gigi pinion jumlah 12 memiliki efisiensi power engine 65,1 %. Jadi kesimpulannya gigi pinion dengan jumlah 11 lebih efisien 3,4 % dibanding dengan gigi pinion dengan jumlah 12. Sehingga gigi pinion jumlah 11 mampu menghemat tenaga engine dan menghemat konsumsi bahan bakar engine.

The increasing number of vehicles every year has led to the rising potential of vehicle accidents. In 2015, there were 556 fatalities from 6,231 accident cases occurred in Jakarta, through regulation of the Minister of Transportation Republic Indonesia No: 111 in 2015, it has been issued firm vehicle speed restrictions, but there is no positive impact because the speed limit of each vehicle cannot be done automatically by the highway location, so the need for innovation to design a tool that can meet these needs. The method in this research is developing a device that can break the flow of fuel quickly to hold the vehicle's speed with a Global Positioning System (GPS) as a trigger to drive the relay that has been installed on the engine. The results of this study are devices that have been installed in truck and bus engines capable of holding the speed. The result shows that the voltage has been calculated was at 10 km/h produce 1.2 volts, and the highest speed of 70km/h produce 10.7 Volt. GPS in speed limiter is also compared with the Map application. The result shows a slight difference either in latitude or longitude, where the smallest differences in latitude and longitude were about 0.00" and 0.05", respectively. In addition, the GPS speed limiter well performs to limit the speed of trucks and buses for 32 km/h in pedestrians, 58km/h on the highway and 52 km/h on a toll road.

Nickel Oxide (NiO) have widely applied in industrial and automotive to forming oxide layer on the substrate due to it have high thermal stability and corrosion resistant. However, NiO was not directly diffused to the substrate via co-precipitation, spray-pyrolysis and sol-gel methods. Therefore, NiO-electroplating was performed in coating FeCrAl substrate by γ-Al2O3 powder. This method was conducted using various time of 15, 30, 45, 60 and 75 minutes, a current of DC power supply is 1.28A and sulphamate type solution. From the data shows that smallest surface roughness (Ra) of NiO-electroplating (EL) samples located at EL 30 min sample for 0.69 µm. Ra of raw material was lower than coated samples due to it performed by coating activity on the substrate. It supported by coating thickness analysis that treated samples has a higher coating thickness up to 11.3 µm. EDS analysis observed some elements on coated and uncoated samples such as Carbon (C) of 4.62-20.67%, Oxygen (O) of 6.16-19.62%, Nickel (Ni) of 6.76-25.14%, Iron (Fe) of 23.96-48.53%, Sodium (Na) of 2.21-9.95%, Chromium (Cr) of 7.97-15.59% and Aluminum (Al) of 2.17-3.12%. Those elements promote to develop a protective oxide layer on FeCrAl at a high temperature of 1000 0C.

PERFORMANCE AND EXHAUST GAS TEMPERATURE INVESTIGATION OF CERAMIC, METALLIC AND FeCrAl CATALYTIC CONVERTER IN GASOLINE ENGINE Hadi Pranoto; Dafit Feriyanto; Supaat Zakaria

Catalytic converter (CATCO) and its effect on engine performance and exhaust gas temperature became an exciting field in automotive research. In this study purposed to compare existing CATCO which is ceramic and metallic with FeCrAl CATCO that treated with a combination of ultrasonic bath and electroplating technique in 30 minutes holding time (UB+EL 30 min). This study proposed to select an appropriate CATCO that used in a gasoline engine to increase the performance and to reduce the exhaust gas temperature as well as its potential to reduce the exhaust gas emission. Mitsubishi 4G93 conducted this analysis with 1.8 L and 10.5 compression ratio with a variable speed of 100, 2000 and 3000 rpm and different engine load of 10, 20 and 30%. The result shows that the FeCrAl CATCO was more useful to reduce fuel consumption up to 66.42% and increase torque up to 15.79% as well as reduce exhaust gas temperature up to 30.11% as compared to ceramic and metallic CATCO. It can be concluded that FeCrAl CATCO coated by UB+EL 30 min was recommended to increase engine performance and to reduce exhaust gas emission.

In 2015, there were 55 deaths from 6,231 accident cases that occurred in Jakarta. A severe problem in Indonesia is the absence of a unique safety device in both commercial transport or personal vehicles and the very high complexity problem of human highways. Consequently, there are many traffic accidents caused by the negligence of the driver, such as driving a vehicle in a drunken, tired, drowsy, or over-limit speed. Therefore, it needs to be innovative using devices to increase speed but able to detect the level of tired or sleepy drivers. This paper tries to propose a concept of improving safety engineering by developing devices that can control the speed and level of safety of trucks and buses, named SLIFA. The proposed device captures the driver's condition by looking at the eyes, size of mouth evaporating, and heart rate conditions. Theses condition will be measured with a particular scale to determine the fatigue level of the driver. Some performance tests have been carried out on truck and bus with 122 Nm and 112 Nm torque wheels and 339 HP and 329 HP power values, respectively, and the minimum speed is 62 km/h. At a top speed of 70 km / h, the torque and power of the truck are 135Nm and 370HP, with average fuel consumption of 3.43 liters/km before SLIFA installation and average fuel consumption of 4.2 liters/km after SLIFA installation. SLIFA can be said to have functional eligibility and can cut fuel consumption by 81 percent.
