Abstract

Oil and gas industry is a sector that has a vital strategic role on national development. East Java is one of the province in Java that has an enourmous potential on oil and gas and has not been optimally explored. Industrial cluster is an industrial development concept that comphrehensively organize the relationship and behaviour of stakeholder in industry so that they can co-operate to increase the competitiveness of the industry. The increasing of industrial competitiveness is supported by completeness and contribution of each industry in oil and gas industial cluster in each java by identifying the behaviour of stakeholder and system in this sector which is described in stakeholder model and value chain model. In this research, lubricant industrial cluster is used as an embryo for developing oil and gas industrial cluster. The complexity of the system in terms of system behaviour will be presented in a dynamic system model, which will make it possible to identify the influence between each variables.The Porter’s Diamond model is adapted to model the behaviour of the competitiveness. The result of this research showed that in increasing the industrial cluster competitiveness some variables are significantly influencing then the others.

Abstract

The vehicle routing problem is investigated by using some adaptations of the variable neighborhood search (VNS). The initial solution was obtained by Dijkstra’s algorithm based on cost network constructed by the sweep algorithm and the 2-opt. Our VNS algorithm use several neighborhoods which were adapted for this problem. In addition, a number of local search methods together with a diversification procedure were used. The algorithm was then tested on the data sets from the literature and it produced competitive results if compared to the solutions published.

Abstract

Composite is arranged from material with function as matrix that has weaker characteristic and material with filler function that has a function to transfer force from load in matrix. Plastic has more advantages than other materials;those are, able to be formed finely, light in weight, easy to get and the price is cheaper relatively. However, the problem is the filler that is involved here is still using fiberglass in which it will disturb human health. Alumina dust used here is Merck by particle size of > 0.063 mm, to get nano size then it would be mixed by Mixer Ball Mill for 50 hours and would be measured for dust grain size with particle size analyzer (PSA), then it is dehydrated in the oven by temperature of 80° C. The percentage of nano alumina for each are 1%, 2%, 3%, 4% ,5%,6% and 7%. Furthermore, it is mixed with PP plastic grain that is conducted by internal mixer to ensure the material distribution evenly, then it is poured in hoper in injection moulding machine that is operated in the temperature of 170° C and is injected in sample test moulding. The result of characterization of tensile strength, modulus elasticity and tensile show the decrement by addition of 2–3% of nano alumina in polypropylene matrix.

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.
