Abstract

Industry must have good quality for their services or products. One of the things that their have done is how to get the customer’s belief in their brand. Quality in every part has become the main case. Most of the companies in industry use metals as material to support their services. When the goods have been processed, it must continue with the testing. This is to prove that the goods have gone through the formation process fill in standard quality which required by the customer. There are two types of testing known as destructive testing and non-destructive testing. There are some of ways of non destructive testing methods on metals inspection has been applied in testing the quality of goods. Such as visual test, magnetic particle test, liquid penetrant, eddy current test, ultrasonic test, radiographic test in metals testing. Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. Radiographic Testing (RT) is a nondestructive examination technique that involves the use of either x-rays or gamma rays to view the internal structure of a component. In the petrochemical industry, Radiographic Testing is often used to inspect machinery, such as pressure vessels and valves, to detect for flaws. RT is also used to inspect weld repairs. Compared to other NDT techniques, radiography has several advantages. It is highly reproducible, can be used on a variety of materials, and the data gathered can be stored for later analysis. Keywords—radiographic, non-destructive testing, piping, examination

Abstract

Reservoir is a large building made by humans by damming a river (Wetzel, 2001). Reservoirsare also an intermediate system between rivers (lotic waters) and lakes (lentic waters). Themanufacture of reservoirs generally has objectives and functions, one of which is for raw water needsfrom drinking water treatment. MG Reservoir is the main source of raw water for PDAM BalikpapanCity. MG Reservoir is a very important aquatic resource in terms of its ecological and economicfunctions. Therefore it must be maintained both in terms of quantity and quality. With the existence ofvarious human activities around MG Reservoir, it will affect the condition of the reservoir. Keywords— evaluation, quality, physics, temperature, transparency, electrical conductivity

Abstract

Thermoelectric Generator produces electrical power through the direct conversion of heat energy into electrical energy. It operates on the same principle as the thermocouples that are used for measuring temperatures and in safety shutoff controls for gas water heaters, home furnaces, etc. However, the TEG utilizes semiconducting thermoelectric materials that are much more efficient and thus permit practical thermoelectric power sources. A thermocouple consists of two dissimilar materials (usually in wire form) which are joined together at one end. If this junction is heated to a higher temperature than the other end of the wire, a voltage will exist across the cooler end. Further, electrical power will be delivered to a load placed in the circuit. This process will continue provided that the temperature difference is maintained. A THEG is a system which provides the means to maintain these required conditions. Key Words : thermoelectric, generator, power plant, installation

Abstract

A pump is a machine used to move uncompressed fluid from one place to another with a certain distance, from a low to a high place or move fluid from a low pressure place to a high pressure place. The purpose of this study is to determine the performance value of the centrifugal pump and the decline from the previous test by the manufacturer, as well as what factors influence it. Retrieval of data in the PT.PHM senipah field is a fire extinguisher pump P-8300 C by reading directly the existing parameters in the form of exhaust pressure (P) and the amount of flow in the exhaust channel (Q). The data is analyzed to get the value of head speed, head loss and total head so that the performance will be obtained. Key words: Centrifugal pump, working fluid, performance.

Abstract

The combustion air system in general is a system that functions as a medium for transporting coal to the boiler as well as adding oxygen for the combustion process and making turbolence. Tomaintain efficient combustion in the boiler, the air after combustion must be adjusted to the amount ofcoal that will be burned into the furnace. While the exhaust gas system is the output of the combustionprocess which is used to transfer hot gas from the rest of the combustion process to the water andsteam pipes and air heating elements, after which the exhaust gas is channeled into nature. Before theflue gas from combustion is disposed of directly into nature, it must first meet the quality standards ofthe Ministry of Environment and Forestry for gas emissions. Keywords—PLTU, Boiler, Combustion Air and Flue Gas System
