Trash ex instant beverage packaging with other plastic waste is often the cause of flooding due to blockage of the flow of water . Among the former garbage instant beverage packaging that contains no aluminum foil ( a thin layer inside the wrap ) and can be recycled for free through the element aluminum smelting way . Aluminum element in packs of instant beverages including former drug packaging collected as marketable.
The plastic waste collection efforts in addition to utilizing aluminum as a material useful in order not to waste reduction efforts are of great help due to the flood of plastic waste that often clog drains . ( cara pengecoran aluminium )
Aluminum is a metal that is widely used in various purposes such as to coat the aircraft body , for home furnishings , for canned drinks because it can provide good mechanical strength , corrosion resistant , and has a good cast - able .

Technology melting process can be done in a conventional manner with a technology that is simple yet effective in obtaining aluminum bars .
The materials needed in this recycling process includes primary material and support material . The main ingredient is a material consisting of trash packs of instant beverage or drug packs containing aluminum foil and if there is a plus anfalan ( junkyard ) such as beverage cans , pieces of aluminum plate or pipe .
Supporting material in the form of greyhon , required at the time of a fire .

Supporting material in the form of greyhon , required at the time of a fire .
The tool consists of a smelting furnace melting inside a drum coated refractory bricks , iron stirrer for leveling flame , ladle to pour the liquid aluminum and steel molds to freeze the liquid aluminum .
The furnace includes all equipment that is still underdeveloped deliberately created to save production costs . Furnaces are used this fruit amounted to 9 maximum when operated will produce 10 aluminum rod or if the raw material is good enough to produce aluminum metal ± 1 quintal per day .
In the smelting process , initially aluminum foil packaging waste that is gradually incorporated approximately 50 % of the capacity of the furnace . Next enter greyhon ( fuel ) that is wrapped with grenjeng ( cigarette tin foil ) and lit the fire . When the fire starts to burn greyhon continuously added to the enlarged fire .
After that all the main ingredients and anfalan ( junkyard ) aluminum inserted until the furnace is full . Wrap aluminum foil continuously stirred and pressed to help speed up the melting .

If there has been a melting aluminum metal then impurities that float in the form of discarded wear ladle slag . Aluminum pouring molten metal into a steel mold was also performed using a ladle . Freezing with liquid metal open air until it is cool and safe to handle lasts for 10-12 hours . After a while the molten metal solidifies ( called castings ) are then removed from the mold . Castings are then prepared for analysis using a microscope optical microstructure or hardness tested using a micro hardness tester .
Quality of the aluminum smelting process can be determined by analyzing the microstructure is through metallographic techniques or microscopy . A state of the microstructure , in this case the grain size ( grain size ) affects the mechanical properties of the metal . Metallographic workmanship on metal castings will show microstructures that help qualitative and quantitative interpretation .
Stages of the work carried out to analyze the microstructure of metals such as aluminum alloy castings include sampling - cutting sectioning ( sampling ) , coarse grinding ( coarse grinding ) , mounting ( planting ) , fine grinding ( fine tuning ) , rough polishing ( polishing rough ) , final polishing , Aluminum castings subsequently etched with a reagent of chemical mixtures such as: 10 mL HCl + 30 mL HN03 + 5 g FeCl3 + 20 ml H2O .

Some common methods of etching include optical methods , electrochemical ( chemical ) , and physics . Etching by chemical methods would most practical and done in this experiment . In the technique of etching solution reacts with the surface etcher footage without using electric current . This method of etching events taking place by the presence of selective dissolution in accordance with the electrochemical characteristics possessed by each material surface area . During etching , positive ions leaving the surface of the metal material and then diffuse into the electrolyte test equivalent to the number of electrons contained in these materials .
In the etching process directly , if the metal ions leave the surface of the material and react with non- metal ions in the electrolyte to form insoluble compounds , then a layer of precipitation will form attached to the surface of materials with different types of thickness . The thickness of this layer as a function of composition and microstructure orientation is separated into a solution . This layer can display interference patterns caused by variations in color and thickness of the layer is determined by the microstructure of the metal that is underneath .

Footage which is part of the pieces of aluminum castings results observed with Optical Microscopy and do a photo shoot . Observations on the picture of microstructures , generally showed the presence of the parent matrix form brightly colored and dark colored particles that lead kebatas grains . The number of particles on the dark colored objects cast result generally depends on the speed of the cooling rate . The faster the cooling rate , the rate of grain growth will be lower than the nucleation rate , so that the grains to expect ¬ silkan be refined so that the hardness and tensile strength will be high .
Based on the metallographic technical experience to get the look of contrasting metallic surfaces , especially between grain boundaries , the decisive factor is the skill of the technician in principle in the preparation of samples ranging from sampling to polishing . Furthermore , at the time of etching the factors that determine the success formula is knowledge in choosing the right method of etching follows . Another factor that is also important is the ability to apply the setting light microscopy techniques and mainly focus image between the metal grain boundaries .
