Abstract

Specific objectives and targets to be achieved are the new business entrepreneurs in the field of manufacture of canoes (canoe) for water vehicles, especially in the river Winongo and generally in places of tourism in other areas. This new entrepreneur will be made in Kampung Pojok, Sinduadi Urban Village, Mlati Sub-district, Sleman Re-gency, DIY (Winongo west side bank). Canoe manufacturing starts from the design (design) of construction which in this case ask for help 4 students of Mechanical Engineering Department and Industrial Faculty of Engineering UGM. Based on the design drawings can be calculated the amount of aluminum alloy material in the form of a 2 thick plate and pipe ¾ inch for the construction of the amplifier. The cutting of the plate is carried out with the betel in accordance with the drawing (the initial stage) and smoothed with hand grinding prior to connection with the electric welding with aluminum alloy electrodes. Similarly, the reinforcing and buoying rods are sawn with a hand saw (initial stage) and connected with an electric weld. In the end the product is tested in the flow of Winongo River, near the canoe production place in the village of Pojok, Sinduadi, Mlati, Sleman. Canoe products are tested by students of the Yogyakarta Maritime Academy. Test results should show no leakage in each canoe connection when in use and on reliable stability conditions. Keywords: Canoe, Water Vehicle, Winongo River, Reliable, Aluminium

Abstract

Shield Metal Arc Welding (SMAW) merupakan salah satu cara yang biasa digunakan untuk pengelasan baja karbon rendah. Kualitas sambungan las dapat dikarakterisasi dengan pengujian tarik, fatik, kekerasan Vickers, dan strukturmikro. Penelitian ini bertujuan mengkarakterisasi sambungan SMAW baja karbon rendah menggunakan 3 jenis elektroda.Penelitian ini menggunakan baja karbon rendah 0,113 %C berdiameter 19,05 mm, dilas menggunakan elektroda E7018, E7016, dan E 6013. Karakterisasi hasil lasan menggunakan  alat Universal Testing Machine, Vickers hardness test, rotary bending fatigue,  dan optical microscope.Hasil penelitian menunjukkan lasan menggunakan elektroda tipe E7018 menghasilkan kekuatan tarik maksimum, UTS : 453,73 MPa,  nilai kekerasan Vickers, HVN : 148,23 kg/mm2 , sedangkan hasil lasan menggunakan tipe E7016 dan E6013 berturut-turut UTS : 442,11 dan 406,27 MPa, HVN : 142,30 dan 119,63 kg/mm2. Kekuatan sambungan las lebih rendah dari material baja karbon rendah as received yaitu 489,47 MPa. Hasil pengujian fatik berturut-turut mempunyai nilai ketahanan fatik (Se) : 204,18; 198,95; 182,82, dan lebih rendah dari Se baja S10C yaitu 292,59 MPa. Pengamatan strukturmikro logam las untuk 3 tipe elektroda didominasi struktur ferit batas butir (GF) dan perlit.
