Â
Pengaruh bentuk sisi sambungan las antara aluminium A 5083 dan tembaga C 11000 yang diproses dengan friction stir welding terhadap sifat mekanik dan struktur mikro telah dievaluasi. Jenis sisi sambungan yang digunakan adalah linier-shaped, tooth-shaped dan saw-shaped. Tool yang digunakan berbentuk trapesium yang memiliki pin berulir dengan jarak pitch 0,5 mm. Parameter proses dibuat konstan yaitu putaran spindle 1500 rpm, traverse speed 24 mm/min, kemiringan tool 2°. Hasil pengujian menunjukkan nilai kekuatan tarik sambungan las dengan bentuk sisi linier-shaped adalah 151 MPa, tooth-shaped 113 MPa dan saw-shaped 167 MPa.
 Kata Kunci: Las, struktur mikro, rpm, kekuatan, sambungan.

Abstract
Â
The effect of welding joint side between aluminum A 5083 and copper C 11000 processed by friction stir welding on mechanical properties and microstructure were observed. Linear shaped, tooth shaped, and saw shaped were used as welding joint side. The trapesium tool with pin screw was used in distance pitch of 0.5 mm. The parameter process was set constant for 1500 rpm, transverse speed 24 mm/min, and tilt angle 2Ëš. The results show that the tensile strength of linear shaped welded joints with 151 MPa, tooth shaped 113 MPa, and saw shaped 167 MPa.
 Keyword: Welding, microstructure, rpm, strength, joint.
