Abstract

Submerged Arc Welding (SAW) is a welding process used for fabrication of pipes, for example spiral welded pipes. The technique can be operated automatically and has a high reliability in many various welding applications. Some factors affecting the strength of weld metals are heat input, current, and chemical composition of filler, flux, and base metal. The present investigation aims to study microstructure-hardness relationship of submerged arc spiral welded steel pipes. Material used in this experiment was API 5L X-52 and API 5L X-60 for spiral welded steel pipes. Welding was carried out using voltage of 35 volt, welding speed of 13,67 mm/s whereas composition Mn on the flux was varied, 1.7; 1.4; 1.4 with Mo and 1.09. Microstructure and hardness were conducted on base metal, weld metal and heat affected zone (HAZ). Results show that, an increase in composition of Mn could be increases the amount of acicular ferrite structure in weld metal. The hardness and thougness number is increase correlated with increase number of Mn, but for the composition Mn as 1,7, the number of acicular ferrite is decrease, the consequence of hardness number is decrease.

Abstract

Globalization is happening at the present time, have an impact on all aspects of human life, including how humans acquire and convey information. As the world becomes cosmopolitan, so as to create cultural uniformity that makes human communication affect each other even though the place is very far apart. One of the demands of globalization is the information accessible to the whole society. Thus, the existing media industry should be able to meet that demand. One effort that needs to be done by the media industry is to make the adjustments to the advancement of existing technology. The globalization of information that played by the media industry has put developing countries as a share of the world information society that requires the establishment of regulation and use of information technology in each country in response to developments in both regional and international levels. Activities use of information technology should be developed without compromising the rights of audience in a fair manner, so that the violations related to the use of information technology can be avoided through the application of uniform principles and rules in each country.

Abstract

The effect of fluids flow rate onto necessity of current density cathodic protection which characterized using Rotating disk electrode (RDE) model has been researched on an electrochemistry manner. This research was done to AISI 1018 steel as the electrode spinning cylinder-shaped inside aerated dissolvable NaCl 3.5%. using variation spinning rate 0–2000rpm and 25–75° C temperature. Current density cathodic protection necessity determined from the steel interface potential - 800mV with reference anode Ag/AgCl. Experiment result shows that the increasing of electrode rate, cathodic protection current density needs increased due to diffusion layer tare faction and also because corrosion potential become more positive. Higher temperature would increase cathode protection current density needs and makes corrosion potential more negative. Oxygen activation energy value to be diffused onto electrode surface support the corrodibility AISI 1018 toward temperature increment, because cathodic reaction controlled by transfer mass of dissolved oxygen.

Abstract

Hard and crunchy are specific characteristics of fried product prefered by consumer. To have texture of crunchy product being suitable with consumer taste, it is necessary to observ characteristic change of raw material and frying condition. In frying process, the changes of hardness and crunchiness characteristics of food occur. These changes are predicted caused by free water vaporization and the decrease of starch content in food. The objective of this research is to develop mathematical model of hardness and crunchiness changes as the function of water and extract content degradation. Sample of the research is jack fruit fried in the temperature of 70–100° C, duration of 15–60 minutes, and pressure of 80–90 kPa. The parameters observed are hardness and crunchiness, water and starch content before and after frying. The result showed that hardness and crunciness change as the function of water vaporization and the decrease of starch content can be used to predict hardness and crunciness of product during vacuum frying.
