The increasing of vehicle uses will make the increasing in fuels consumption. In the other hand, the reserves of fossil fuels as a fuel in vehicles are always decreasing. In order to anticipate the lack of fossil fuels, there is some alternatives energy that has to substitute the fossil fuels. One of the alternative energy is HHO Gas. HHO gas is a gas that was produced by the electrolysis of water. Water as an abundant material in earth can be an alternative energy that replace or substitute fossil fuel. In this research, HHO gas will be used as a supplement in fuels. So the vehicles use two fuels (bi-fuel. )The aim of this research is to analyze the performance of uses HHO gas in vehicles. The HHO gas will be produced by different water, such as aquadest, land water, sea water. The performance analysis was focused in the fuel consumption and the efficiency of thermal engine oil. The analysis result shows that the addicted HHO gas can make the efficiency of fuel consumption better. The highest efficiency fuel consumption is in the fuel with HHO gas from aquadest (19.95%). But the best efficiency in thermal engine oil is in HHO gas from sea water (0.84 oC). Keywords: HHO, performance, engine, bifuel

Rolling Resistance is a resistance to the wheels that will and have been rolling due to the force of friction between the wheels with the road surface of the wheel. Rolling resistance is influenced by four factors, that is vehicle weight, road surface, transmission, and tires. This study usefull to determine the influence of tread pattern surface to force and coefficient rolling resistance, tire surface contact area and tire pressure value. In this study using motorcycle tires with size 90/90-17. The tire used is a tire with RIB tread pattern (straight groove) and LUG tread pattern (zig-zag groove). Each type of RIB and LUG tread pattern used each of two tires that is the type of simple tread pattern and the complex tread pattern. From the results of the study showed that the tire with a simple tread pattern will produce a small force of rolling resistance but will result in a larger surface tire surface contact than the tire with the complex tread pattenr. While for the tire with the type complex tread pattern has a greater pressure value that will produce a great rolling resistance force. For tires get the best rolling resistance force is the tire with a simple LUG tread pattern of 10.234 N and followed by a tire with a simple RIB tread pattern type of 10.563 N. Keywords: tread pattern, rolling resistance, rib, lug.

The synthesis of nanoparticles using thermal DC plasma method is a simple method for ease of installation and high efficiency is due to the rate of precursor that can be controlled. Micro-sized aluminum powder is synthesized using thermal DC plasma undergoing a process of evaporation as it passes through high temperature plasma flame, where kemuadian oxidized aluminum particles which evaporates the particles are split and binds with oxygen to form aluminum oxide or also known as alumina (Al2O3). In this experiment, the flow rate of oxygen plasma parameters at 35 SCFH (Standard Cubic Feet per Hour) and 20 amperes flows with precursors rate variation of 1.16 g / min, 3.19 g / min, and 3.5 g / min. Precursors used is 88 micro sized aluminum powder. To determine the morphology of nanoparticles of alumina testing scanning electron microscopy (SEM), the morphology form of nanosphere. Results of the analysis showed that the rate of precursor low causing agglomeration level slightly while the higher rate of precursor agglomeration rate also increased. At the rate of precursor 1.16 g / min, nanoparikel undergo agglomeration with an average particle size of 36.55 nm, and then at a rate of 3.19 gr precursor / mnt an average particle size of 46.49 nm, and at a rate of 3.5 gr / mnt an average particle size of 46.49 nm. The powder nanoparticles were then characterized using X-ray defraksi (XRD) where all alumina nanoparticles were synthesized showed alumina phase that is formed is a phase δ-Al2O3.

This study is aimed to determine the effect of post-treatment plasma CVD on diamond-like carbon films of surface hardness AISI 410 steel. Enhancement of surface hardness on AISI 410 can be done with deposition thin layer by plasma CVD, and continued by post-treatment plasma CVD. Mixture of Ar (90%) with CH4 (10%), and He (76%) with CH4 (24%) are used as thin layer material. Deposition parameter of pressure, temperature, and time that been used are 1.6 mbar, 300 °C, and 4 hours, respectively. Furthermore, post-treatment process parameter is used by Ar gas, with pressure of 1 mbar, temperature 300 °C, and variation time of 10, 20, 30 minutes. Surface hardness test is used by Vickers microhardness tester. Cross-section microstructure and chemical compositions are examined by scanning electron microscopy coupled with energy dispersive spectroscopy. Based on surface hardness test, the surface hardness on AISI 410 is increased by post-treatment process. The surface hardness from 232.3 VHN increase to 301.2 VHN is produced by post-treatment of compound Ar-CH4 in 20 minutes. Futhermore, the surface hardness from 1,035.8 VHN increase to 1,743.2 VHN is produced by post-treatment of compound He-CH4 in 30 minutes.

Transport is one of the main community needs, but along with the increasing number of transport such as motorcycles and increasing also use of fuel oil.While fuel oil are currently derived from fossil where is not sustainable, alternative fuel can use water as fuel, by the process elektrolysis. Water is a compound composed of hydrogen and oxygen, both compound this is a flammable that can be used as alternative fuel or known as gas HHO . When used alternative fuel, gas HHO used along with fuel oil (bi-fuel) .This research discussed of the use of a generator HHO (tool gas producer HHO) on a motorcycle to a variation with an electrolyte namely fresh water, sea water and aquadesh in order to know some of the form a generator HHO that is the generator, the rate of the production of gas and efficiency of gas.

Corrosion is the degradation of the material surface due to reaction with the environment. Steel pipe is one of the materials vulnerable to corrosion because the piping system is always in contact with the outside environment. This research have a purpose to know influence of cold working about corrosion resistance pipe A53 on oil sludge salt water and oil sludge pond environment with c-ring method. Oil sludge is sediment of crude oil thats contain water, sediment, and oil thats can be processed again. The cold working process is carried out by providing bending loads of 114 kg, 140 kg, and 160 kg, and one material without bending. Process of corrosion testing uses weight loss method by weighing the material before it is corroded and after corrosion. Result of test showed that there was an increase of hardness on the material with bending load of 114 kg, 140 kg, and 160 kg respectively of 103.33 BHN, 134.00 BHN, and 187.66 BHN, while the material without bending had a hardness of 93.33 BHN. Corrosion rate on material without bending with oil sludge salt water is 2,12 x 10-2 mmpy while in oil sludge pond equal to 1,67 x 10-2 mmpy. Materials with bending loads of 114 kg, 140 kg, and 160 kg have a corrosion rate of 2.35 x 10-2 mmpy, 2.88 x 10- 2 mmpy, and 4.18 x 10-2 mmpy on oil sludge salt water, and 1.19 x10-2 mmpy, 2.15 x 10-2 mmpy, and 3.09 x 10-2 mmpy on oil sludge pond. Oil sludge of salt water is more reactive than oil sludge pond because it contains sea water composed of NaCl compounds which is a corrosive environment .The given bending load results in strain hardening followed by increased energy on the material so that the corrosion rate increases. Cold treatment provided resulted in cracks on the surface of the material so that the corrosion was localized to the crack and formed pitting.
