This paper presents a study of deformation and failure performances of a plastic sheet made of polymer alloys subjected to drop weight impact of a cylindrical mass with hemispherical tip at a certain velocity by using dynamic explicit finite element…
The purpose of this study is to determine the effect of variations in the use of fillers for particle board. Various composition of fillers from rice husk and wood sawdust were mixed with synthetic glue matrix of PVAC (Poly Vinyl Acetate Co-Acrylic)…
PT. Arun NGL has made various efforts torecover losses of energy and water resources during the production process. One of the main focuses for energy conservation is flare gas recovery unit. The flare gas recovery system proposed is skid-mounted…
This paper discussed a preliminary study of low-frequency stick-slip of a creep groan using a simple caliper-slider model. The experiment model is constructed based on the real operating system behind a vehicle braking system. The model consists of a…
The increase of population, followed by the increasing growth of the industry led to high demand of electricity. Many different ways have been done to find and use natural potential as electrical energy that can be used. The potential energy of water…
Air conditioning and heat pump systems can use the ground as a medium to dump or absorb heat energy to increase efficiencies. As compared to the air, the ground has lower temperature in the summer and higher in the winter. In this research, the…
Experimental investigations to study significant effects of employing a post weld heat treatment (PWHT) technique on mechanical properties of the welded carbon steel have been performed. This paper presents a study on hardness and tensile strength…
Marine observation and research activities require a suitable transportation means that has an ability to bring necessary equipment for data collection and observation into the sea. One of the means that has the ability is AUV (Autonomous Underwater…
Coconut fibre which is extracted from outer shell of a coconut is a type of natural fibre used as composite board reinforcement in this research. The fibrebinder used in this research was stryrofoam which is a material from polysterene. This research…
Indonesian ocean has a riches of maritime fishery potency, so fishery mapping is important to be maintained, examined and explored. Fishery potency observation requires a vehicle to bring the observations and data collection equipments to the…
