Abstract

The problems faced are aluminium (Al) waste from industries that damage the environment and scarcity of Al raw materials that need to be recycled from used Al. The research objective was to determine the effect of adding magnesium (Mg) to used Al casting on the tensile strength and microstructure and to determine the comparison of the tensile strength of the Al material used by the piston to the brake lining and drum of motorcycles. The research method includes casting Al used pistons, brake lining and drum, testing the tensile strength and microstructure due to the addition of 0.1; 0.2; 0.5 and 1.0% by weight Mg to the tensile strength and microstructure. The results showed that the addition of Mg 0.5% by weight could increase the tensile strength of 92.96% from 71 MPa to 137 MPa for brake lining as the optimum value which further decreased the tensile strength by 19.7% at the addition of 1% Mg to 110 MPa. Drum material also experienced an increase in tensile strength of 33.71% from 89 MPa to 119 MPa as the optimum value where the tensile strength decreased by 5.88% for the addition of 1% Mg to 112 MPa. The two values of the tensile strength of the brake lining and drum components are lower than those of the piston component valued at 147 MPa, and with the addition of Mg, Mg2Si is formed which can reduce the porosity of the microstructure, thereby increasing its strength.

Abstract

Human development and national competitivenes is one of the flagship programs from The Indonesian Government. Bali as one of the best tourist destination in the world is required to have an international standard tourism infrastructure. A swimming pool in a tourism accomodation is a standard facility in a tourist infrastructure. There are several types of swimming pools i.e. public swimming pools and private pools. During its development and demand, private pools develop into swimming pools with additional facilities such as warm water, which is often called a jacuzzi. Another additional facility is added pressure to the water in completing massage, fragrance and foam. The swimming pool is one of facilitity designed to hold water to allow swimming or other recreational activities. Pools can be built in the ground or on the ground as a free construction or as a part of structure and also with a common feature or a free style design. In-ground pools are the most common pools made and constructed from materials such as concrete, natural stone, metal, plastic, or fiberglass. To support comfort and satisfaction when using the swimming pool, the adequate water level in the swimming pool will be maintained by system with several supporting devices such as pumps, dirt filters and maintained at a certain level. Other things that support water quality include temperature, water turbidity, color, odor, pH, chlorine content etc.
