Steel casting has been done using sand molds, both river sand and silica sand, tends to experience casting defects, especially surface defects. One way to overcome surface defects is to use sand that has a higher melting point, including chromite sand and zircon sand. Chromite sand has a higher price, so it is often mixed into silica sand, but this...

This paper discusses the bending stresses of the hexagonal honeycomb sandwich panel structure made of glass fiber reinforced polymer (GFRP) composite. The 1D axial hexagonal honeycomb sandwich panel structure consists of a honeycomb core and thin wallsheets. The plastic steel epoxy resin, polyaminoamide-bisphenol-A resin, and thermosetting resin we...
The demand for renewable fuels increases as fossil fuels supplies decreased. Ethanol has the potential to be used as an alternative to petroleum gasoline. The performance of gasoline four-stroke spark ignition engine was analyzed using fuel grade ethanol (E96) as a replacement fuel. The pressurized air was used on the fuel injection system, and the...

The bumper car made of the Pineapple Leaf Fiber Reinforced Composite (PLFRC) is possible to be produced with the advantage of easy to get, and cheap. Pineapple leaf fiber has chosen as a natural fiber, which the maximum of the strength of 368 MPa. The objective of this study was to determine the maximum capability of front car bumpers using Pineapp...
Rice husk particle board was expected to replace the other particle board which has advantages i.e. more heat and fire resistance that can be used in household appliances, building materials, heat absorber, and cold storage. As alternative building material, rice husk particle board should pass the testing processes that suitable to industry standa...
Effect of plate joint on automobile body which susceptible to corrosion has been investigated also corrosion rate on automobile plate when the coating has impacted. Rain and sea water was used as corossion medium as normally affected on automobile plate. Low carbon steel has been choosed as standart plate. The forming of plate as a joint which fold...
