Paduan aluminium terus meningkat da

Paduan aluminium terus meningkat dari tahun ketahun. Hal ini terlihat dari urutan pengunaan logam paduan aluminium yang menempati urutan kedua setelah pengunaan logam besi atau baja, dan diurutan pertama untuk logam non ferro[14]. Data jumlah kendaraan di Indonesia tahun 2005 mencapai 38.156.278 terdiri dari roda dua 28.556.498 dan roda empat 9.559.780[12]. Jika hitungan kasar bahwa penggantian kerusakan piston yang terbuat dari paduan aluminium setiap tahunya 3-4% dikalikan jumlah kendaraan, maka jumlah piston 2.255.017 dikalikan 3 ons berat piston rata-rata, sehingga jumlah total berat piston yang diganti yaitu 6.765,5 Ton. Jika satu Ton aluminium dengan harga US$ 3.305 berarti jumlah uang keseluruhan US$ 2.235.849 (Rp 23 Milyar), bila Indonesia dapat menggunakan piston daur ulang maka dapat menghemat 23 milyar. Selain itu, penggunaan piston daur ulang juga dapat menghemat penggunaan bijih aluminium yang persediaan di alam terbatas.
Tujuan dan sasaran penelitian ini adalah memanfaatkan piston bekas untuk didaur ulang menjadi piston baru dengan metode penyisipan besi cor dan baja karbon rendah. Kajian dalam penelitian ini meliputi mengetahui seberapa besar presentase material piston bekas dengan menvariasikan material ADC 12 yang dapat dipakai dalam proses daur ulang, mengamati dari beberapa penyisip yang memiliki kekuatan interface yang paling baik dari pengujian geser antara dua logam, menentukan berapa besar presentasi ADC 12 terhadap pengaruh interface antara beberapa penyisip logam dengan proses pengecoran gravitasi, dan mengevaluasi sifat mekanis (kekerasan, kekuatan geser, komposisi, dan struktur mikro) piston daur ulang sehingga menghasilkan sifat yang optimal. Manfaat yang diperoleh dari penelitian ini adalah mampu meningkatkan penggunaan limbah piston bekas sebagai bahan daur ulang untuk pembuatan piston baru yang berkualitas dan potensi perolehan Hak Kekayaan Intelektual rejim paten.

Aluminum alloys continue to increase from year to year. This is apparent from the order of usage of aluminum alloy metal that took second place after iron or steel metal use, and currently the first metal to non ferro [14]. The Data the number of vehicles in Indonesia in 2005 reached 38.156.278 comprising two-wheeled and four-wheeled 28.556.498 9.559.780 [12]. If a rough count of that permutation piston made of aluminium alloys per year 3-4% multiplied by the number of vehicles, then the number of piston 2.255.017 piston 3 ounce weight multiplied by the average, so the total weight of the piston being replaced is 6.765 .5 tons. If a Ton of aluminum is priced at US $ 3.305 means the overall amount of US $ 2.235.849 ($ 23 billion), If Indonesia can use the recycling piston then can save 23 billion. In addition, the use of recycled piston can also save the use of aluminum ore supplies limited in nature.
the aims and objectives of this research is to utilize the former piston to be recycled into new piston insertion method with cast iron and low carbon steel. The study in this research includes knowing how big a percentage of the materials used with menvariasikan piston material ADC 12 which can be used in the process of recycling, watching from some penyisip who has the nicest interface strength of sliding test between two metals, determine how large the presentation ADC 12 against the influence of interface between some metal penyisip with the gravity casting process, and evaluate the mechanical properties (hardness, shear strength, composition and microstructure) piston recycling thus generating optimal properties. The benefits derived from this research is capable of increasing the use of waste as an ex-piston recycled materials for the manufacture of new high quality piston and potential acquisition of intellectual property rights patent regimes.

Aluminum alloy continues to increase from year to year. It is seen from the order of the use of aluminum alloy metal which ranks second only to the use of metallic iron or steel, and comes out first for non ferrous metals [14]. Data on the number of vehicles in Indonesia in 2005 reached 38,156,278 28,556,498 consisting of two wheels and four wheels 9.55978 million [12]. If the rough calculations that the replacement of damaged pistons are made ​​from aluminum alloys of 3-4% every year multiplied by the number of vehicles, the number 3 piston 2,255,017 ounces multiplied the average weight of the piston, so the weight of the total amount of the replaced piston is 6765.5 tons. If one ton of aluminum at a price $ 3,305 means the total amount of US $ 2,235,849 (USD 23 billion), if Indonesia can use the piston recycling could save 23 billion. In addition, the use of recycled piston can also save the use of aluminum ore supplies are limited in nature.

Studies in this research include knowing how big a percentage of the material to vary the piston former ADC material 12 which can be used in the recycling process, observed from some penyisip who has the best strength of the interface shear testing between two metals, determine how much the presentation of the ADC 12 influence of the interface between the metal with some penyisip gravity casting process, and evaluate the mechanical properties (hardness, shear strength, composition, and microstructure) piston recycled to produce optimal properties. The benefits derived from this study is able to increase the use of waste as a former piston recycled materials for the manufacture of quality new piston and the potential acquisition of Intellectual Property Rights patent regime.
