ABSTRAK

Teknik pembuatan keris dibuat dari gabungan dua atau lebih logam yang ditempa dengan gaya dan temperatur austenit sampai terjadi pengelasan Teknik pembuatan keris ini menjadi dasar dibuatnya komposit laminate pada penelitian kali ini. Komposit sendiri merupakan gabungan antara dua atau lebih material dengan sifat yang dihasilkan berbeda dengan bahan asalnya. Komposit laminate pada penelitian ini dibuat dengan bahan baja dan nikel. Baja pada penelitian ini memakai AISI 1020 dan AISI 1045. Lembaran AISI 1020 ditempa dengan gaya manual pada temperatur 1100o C dan selanjutnya dilipat arah melintang. Lipatan AISI 1020 ini diselipi bahan nikel. Dihasilkan bahan komposit awal dengan susunan AISI 1020-Nikel-AISI 1020. Bahan komposit awal ini dilipat 1 kali arah memanjang dan ditempa pada 1100o C dihasilkan komposit awal 1 kali lipatan. Komposit awal 1 kali lipatan ini dilipat lagi arah melintang dan ditempa pada 1100o C dihasilkan komposit awal 2 kali lipatan. Proses ini berlangsung terus sampai dihasilkan komposit awal 1 3 dan 5 lipatan. Komposit awal ini dipotong menjadi dua arah melintang dan disusun dengan AISI 1045 dengan susunan komposit awal n lipatan-AISI 1045-komposit awal n lipatan. Susunan ini ditempa pada 1100o C yang selanjutnya disebut spesimen komposit akhir n lipatan. Komposit akhir n lipatan ini akan dilakukan pengujian dengan uji tarik uji kekerasan foto makro dan mikro. Kompositl laminat baja dan nikel dengan variasi jumlah lipatan didapatkan bahwa kekuatan tarik keuletan kekakuan dan kekerasan dari komposit laminat baja dan nikel semakin meningkat seiring banyaknya lipatan pada baja AISI 1020 dan Nikel.


ABSTRACT

The making technique of keris in Indonesia is made from the compound of two or more metal which is forged by a force and an Austenit temperature until welded. This technique will be a base of making laminate composite in this research. Composite itself is a compound of two or more material which character produced is different from its base material. In this research it will be made a laminate composite by using steel and nickel. The steel used is AISI 1020 and AISI 1045. A sheet of AISI 1020 is forged by a manual force in temperature 1100o C and then folded in its center transversally. A folded of AISI 1020 is inserted by nickel. And we will get the fisrt composite which formation is AISI 1020-Nickel-AISI 1020. This first composite will be folded once time longitudinally and forged in temperature 1100o C. It will be called as a first composite with 1 folded time. This first composite will be folded longitudinally and forged in temperature 1100o C and called as a first composite with 2 folded time. This process will continue until we get the first composite with n folded. This research use the first composite with 1 3 and 5 folded. This first composite with n folded will be cut transversally become 2 parts and will be set with AISI 1045 which formation become the first composite with n folded-AISI 1045- the first composite with n folded and forged with temperature 100o C. This called the final composite with n folded and we will conduct a test such as tensile test hardness test macro and micro photo. From this making process of laminate composite of steel and nickel with variation of total folded we will get a conclusion that strength elongation modulus elasticity and hardness will increase when the total folded of AISI 1020 and nickel increase.
