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…
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…
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…
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…
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…
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…
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)…
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…
Aceh marine area has many potential resources that need to be explored, studied, and conserved. These activities require a suitable mean that has capability to bring data collection and observation tools into the seabed. One of the means that can…
The study is done to get an axial low head turbine design that gave good performance by using flat blade to further simplifying manufacture. The study is consists of three stages. First, designing an axial low head turbine. Second, manufacturing it…
