Abstract

Hardness test on the alloy Fe-50% at Al with the addition of nickel were prepared by mechanical alloying method. The powder mixture Fe-50at.%Al with the variation adding 0,5at.%Ni, and 2at.%Ni  are grinded using High Energy Milling HEM E-3D in Argon condition for 10 hours. To determine the hardness, conducted to take the sample with the certain time duration to each composition. Then, the sample which has been taken is characterization using hardness. The results showed that the highest hardness properties exist in the alloy Fe-50% at Al-0.5% at Ni, amounting to 161.53 HV. The addition of nickel on alloy reduces the hardness properties of the alloy. However, the addition of nickel require a short time to raise the hardness properties.

Abstract

Fishing boats of fiberglass materials require special care to make the vessel more durable. In the field, often found paint coating ships that have faded and peeling within a few years. Yet it is expected that the vessel can last long to continue to maximize the catch of fishermen. Most of the treatments found on fiberglass boats are light treatments, such as cracks. Cracks from gelcoat and scratches due to impact are maintenance work performed at boat or boat building. The key to fiberglass treatment is how to keep the gelcoat layer of fiber shiny. As is known, layer gelcoat is a very strong layer. But over time, weather changes and exposure to sunlight, this gelcoat layer can fade if not treated properly. In order to avoid these conditions, the most efficient way to do that is coated fiberglass with wax or special polish. Selection of care products for fiber boats also cannot be perfunctory. Certain types of waxes that have anti-ultraviolet rays are highly recommended for treatment. By doing proper maintenance techniques, will make the life of the fiber boat more durable and still look shiny.

Abstract

This experimental study aims to compare the performance and Spesific Fuel Consumsion (Sfc) where were produced from RON 88 fuel and RON 92 fuel with T101D Automotive engine test bed, with optionals tool. Engine gasoline type 1.1 8V was used in this study. The difference of torque which is caused by the use of RON 88 and RON 92 fuel is obtained. The highest torque at occurred 2500 rpm where the comparison between these two is about 4.458 %. Then, the performance of RON 88 has slight difference. The Spesific Fuel Consumption (sfc) of RON 92 fuel is lower than RON 88 fuel sfc. The lowest decrease (sfc) is 21.212% at 3700 rpm and the overall engine decline is 7.796%.

Abstract

Wear of razor blades often occurs when a man shaves his facial. In this paper, the observation of wear characteristic with different types of material and lubricant is investigated. The experiment was conducted on 6 students of the Mechanical Engineering study program with uniform beards and mustaches for 6 weeks. Each week, the wear from the surface of each blade was observed using an optical microscope. Two types of razors were investigared with different materials based on the price, which are consisted of cheap razor (type-A) and expensive razor (type-B), each of which has 3 blades. There were three types of lubricants used, namely: water, liquid soap, and foam. The result shows that type-B razor is better than type-B razor because the material has a high carbon content based on chemical content from testing with Energy Dispersive X-Ray (EDX). Foam lubricant can slow down the wear on razor blades. The 1st blade razor wears out faster than the 2nd and 3rd bladem, respectively.
