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

Nowdays, motorcycles become a primary need for people, especially in Indonesia. This has resulted in the increasing number of motorcycle spare parts waste. The waste is in the form of motorcycle components such as wheels, tires, drums, canvas, gear, chains and pistons and many others. Until now, the community has not used this waste, especially the use of used pistons as raw material for casting connecting rods. Connecting rod itself is a motorcycle component made of aluminum. In this study, the authors wanted to analyze the physical and mechanical properties of the casting (imitation) connecting rods made from used pistons with the addition of Titanium Boron (Ti-B) elements. The characterization of the casting results was analyzed by observing the microstructure and Vickers hardness test. The results showed that the physical properties of the foundry material contained 81.6% aluminum and 13.09% silicon, while on microstructure observations with a magnification of 100x, the Al phase and Al-Si alloys were more dominant. In the Vickers hardness test, the hardness result was 79.59 VHN. This is due to the addition of Ti-B elements which can refine grains and reduce porosity in aluminum silicon (Al-Si) alloys for motorcycle connecting rod spare parts.
