Raw Material is a material that is directly used to be processed and will become a finished product from the company. In this process, aluminum weighing 224,240 kg requires a coolant of 582 kg and electricity of 403,583 kWh. Later, the amount of coolant that will be wasted is the same as the coolant that is needed: 582 kg. The aluminum he processed would later produce unused material in the form of chips of 11,212 kg.
Aluminum produced from the Raw Material process is 213,028 kg. Later, the aluminum was processed using the AR Heat Treatment process. Heat Treatment AR is the process of changing the structure of a metal by heating a specimen at an electric Terrance at a recrystallization temperature for a certain time and then cooling it in a cooling medium such as air, water, salt water, oil, and diesel which has different cooling densities using Argon, respectively. In this Heat Treatment process, 275,058 KWh of electricity is needed.
After going through the Heat Treatment AR process, the 213,028 kg aluminum was divided into two methods of formation which are Machining and Sheet Metal Forming. If the thickness of the aluminum is above 5 mm, then the aluminum will be processed through the Machining process. Conversely, if the thickness of the aluminum is below 5 mm, then the aluminum is processed by the Sheet Metal Forming process.
In this Machining process, 192.756 kg of aluminum will be processed and the process requires a cooling agent of 5,243 kg, 19,858 kg of water, 2,635 kg of chemicals and 1,672,940 KWh of electricity. For the next, the aluminum will produce unused material in the form of chips of 149,213 kg. Coolant and chemicals needed and removed from this process have the same amounts of 5,243 kg and 2,635 kg. The wastewater from this process is 3,310 kg from the amount of 19,858 kg of water used. The remaining 16,548 kg of water can be recycled/reused. The weight of aluminum produced in this proces
Process for protecting aircraft components. This process begins by first cleaning the components that were formed in the previous process and is then coated with various protective materials such as Alodine, Chomic, and Annodize. In this process, 52,645 kg of aluminum requires an electric power of 50,372 kWh and requires 338,162 kg of diesel fuel. This process also uses 431,996 kg of water which will then be recycled 71,999 kg. The chemical used at this stage is 105,304 kg and produces waste that will then be treated at 21,061 kg.
Phase to provide the final touch to aircraft components. The painting process is divided into two processes, including the basic or primary painting process and primary color painting or top coat. The color used for basic colors is green. Meanwhile, top coat colors can use other colors such as green, blue, dark blue, white, and black. Some components may have special colors such as white for tanks or fuel tubes. The white color is intended to make it easier to detect any leakage or other damage to the tank components. The painting uses 164,971 KWh of electricity.
The process gives the basic color to the metal bond yield components. The basic color used is green. In the process of providing basic colors for aluminum weighing 224,240 kg, it requires an electric power of 41,228 kWh.
The combination of two or more materials produces a new material with different strengths or properties to the properties of the material. To process 8,400 kg of composite material, 453,522 KWh of electricity and 61,350 kg of diesel fuel are required. The water used is 127,222 kg with 21,204 kg of recyclable results. The composite process also requires 210 kg of coolant and will be a waste to be treated as much as 210 kg. The amount of chemicals used in this process is 13.913 kg. The composite process also involves 612 kg of STP material.
The process of aggregating all component details to become part of a larger component. At this stage, to combine 6,454 kg of composite and 56,245 kg of aluminum, 2,443,052 KWh of electricity is required and 18,619 kg of diesel fuel. In the process of combining, 270 kg of chemicals is required and 16 kg of waste is left to be treated. This process resulted in 282 kg of debris or chips.
The process of assembling large parts of the aircraft such as fuselage, wing, empennage, and other parts besides aircraft frame parts such as interior, cockpit, and other complementary parts. In the final assembly or assembly process for 56,125 kg of aluminum and 6,595 kg of non-aircraft parts, 1,416,558 KWh of electricity and 14,664 kg of diesel fuel are required. The Final Assembly will produce an end product for the customer with a weight of 56.125 kg and 6,454 kg respectively known as the empty weight of an aircraft unit.
