Design System of High-Velocity Oxygen Fuel (HVOF) Thermal Spray Coating Based on Computerization

Wear and corrosion are problems prevalent in the industrialized world. One way to overcome this matter is the process of coating with a thermal spray coating. The coating process is categorized into two processes based on the heat source, i.e., combustion and electric. One example of combustion process is the high-velocity oxygen fuel (HVOF). The HVOF system which is operated manually has been studied in previous works. Computerized HVOF system is developed and manufactured in this study to improve reproducibility of coating and safety of operator. ATMega16 microcontroller was connected with several sensors (oxygen mass flow controller, nitrogen mass flow controller, propane mass flow controller, and pressure sensor), and Visual Studio.Net 2013 was used to create a graphic user interface (GUI). Based on test results obtained, it was found that the GUI successfully communicated using serial communications and could access the input/output (I/O) required by the microcontroller. Combinaton of gas mass flow controller and pressure sensors result in precise control of oxy-fuel combustion process.

Kajian Kebijakan Manajemen Penelitian di Bidang Pertanian dan Keamanan

As a sovereign nation, Indonesia has a strategy to defend itself against threats from outside and within the country. That requires a strong defense, both in terms of the number of military personnel and the number of defense equipment. So far, we have mostly the weaponry purchased and hung from abroad. This paper discusses the results of the study several policies and government regulations in defense and securi-ty in Indonesia. The methodology used is the start of data collection both primary data and secondary data, and from these data calculated the ideal number of military personnel and defense equipment. From the analysis of the data can be identified that one of the obstacles faced by Indonesian defense is the ratio of the number of military personnel to the personnel composition of the population as well as Army, Navy, and Air Force are still not ideal as well as the number of defense equipment owned is but below standard. In addition, the documents are not MP3EI clear roadmap on the development, engineering, and purchases of defense equipment and targets each year. Another problem is the absence of good coordination on defense research consortium activities. For that recommended the need for cooperation between military R & D, universities, and other research institutions under one umbrella defense research resulting in better research synergy.

Melepas Ketergantungan Subsidi BBM melalui Program Konversi BBG Pada Kendaraan untuk Menuju Ketahanan Energi Nasional

Based on BPS data in 2010, the number of motor vehicles in Indonesia as many as 76.9 million units, the number of vehicles on the island of Java alone approximately 44.4 million units. More than 57% of the number of motor vehicles in Indonesia on the island of Java. This is the background to the potential conversion of fuel oil to CNG fuel for vehicles on the island of Java. In addition, the end of 2014 the gas pipeline Trans Java linking West Java to Central Java and Central Java to East Java will operate. These two components, namely the large number of vehicles and the operation of the gas pipeline Trans Java offer more value than if the conversion program implemented in other islands. Studies have been done on the conversion of fuel oil to CNG fuel vehicles, especially in the area around the gas pipeline Trans Java. This paper will map potential locations for the implementation of the conversion program, conversion targets in each region, the need of CNG, Gas Stations number, size reduction of subsidies, and profits for NGV users. Formulation of strategies are required in migrating to CNG, the mapping problem in doing the conversion, and prepare for technology transfer. Vehicles that will be converted are gasoline-fueled vehicles, consists of public transportation, private and services. For public transport and services. Conversion is done 100%. Non public transportation (vehicles) converted only by 10%. The conversion vehicles will be done for 3 years gradually. Target conversion for 3 years at 1.1 million units NGV. The amount of the required gas allocation as many as 10.7 million klsp, which is needed as many as 2,857 SPBG. Saving from subsidy about 35.44 trillion rupiahs. To make the program successful requires the government policy and good coordination between relevant agencies in particular to overcome obstacles, problems, and to prepare for the transfer of technology.
