ABSTRACT Motor grader is a heavy equipment that has the function of leveling and forming surfaces, peeling soil, spreading light materials, etc. The motor grader's driving tool is the tire wheel located behind the body. In order to understand the movement of the motor grader, it is not possible for us to make it like the original. Therefore, researchers will design a transmission system to dri…
ABSTRACT The global energy crisis has become a major concern in recent times. The world's dependence on fossil fuels causes serious environmental problems such as global warming and air pollution. Vortex turbines are a tool used to convert natural energy potential into renewable energy. One part of a vortex turbine is the basin. Basins are basins that have the function of regulating flow …
ABSTRACT Acoustics is the study of sound including its production, transmission and effects. Sound is the result of the vibration of objects in the form of an analog signal with amplitude that can change continuously with time and propagate through the air. Pipes and piping systems are very important in industry as they play a vital role in regulating fluid flow from one location to another ef…
ABSTRACT Piping system is one of the important components commonly used to move fluid between one equipment to another equipment to pass certain processes or flow fluid between one plant to another plant which usually passes through several areas. Damage to the piping system can cause personal injury, facility damage, environmental damage, and economic loss. Several factors cause damage to pip…
ABSTRACT Aluminium is widely used in everyday applications, including beverage cans and automotive components. The increasing use of aluminium correlates with increasing amounts of waste if not managed properly. Metal casting is one solution for waste processing. The pouring temperature in metal casting greatly influences the final result. This research aims to investigate the impact of castin…
ABSTRACT Used cooking oil is oil that has been used in the frying process. Consumption of used cooking oil has a negative impact on human health, in addition to improper disposal of used cooking oil resulting in environmental pollution. One way to overcome this waste is by processing it into wax material for investment casting patterns by adding chemicals in the form of stearin. This study aim…
ABSTRACT The development of a generator set for the electricity needs of street vendors is an effort to provide solutions to limited electricity access in certain locations. Street vendors often face challenges in providing sufficient electrical power for lighting and operating electronic devices. This study aims to design a generator set based on free energy that is efficient, reliable, and e…
ABSTRACT Indonesia's topographical situation, which has many rivers and irrigation canals, has enormous water energy potential to be utilized and one of the uses is the vortex turbine. Therefore, development was carried out by adding a snail-shaped basin with varying fin lengths and a comparison was made with the cone basin. This snail-shaped basin has a basic shape like a conical basin but fi…
ABSTRACT Bathing in hot water has many benefits and has now become a lifestyle habit for Indonesians. Water is usually heated using fossil fuels or electrical energy, but since these natural resources are non-renewable, the supply is decreasing every day. One solution that has emerged is the manufacture of direct-expansion heat pump water heater. Tests were conducted to determine the performan…
ABSTRACT Currently, humans really need energy for survival. Where on this earth the most widely used energy is fossil energy. Dependence on the use of fossil energy makes its availability increasingly depleted. Therefore, humans are looking for alternative renewable energy to replace fossil energy, namely water. Water can be utilized for its potential to drive power plants. One of the power pl…
ABSTRACT In this research, innovation was carried out on ventilators using wind energy as an electricity generator. Where the rotation of the ventilator turbine is used to drive a DC generator. This research was conducted to determine the effect of blade variations on a 12inch ventilator turbine used for power generation. This research highlights the importance of turbine blade variations on t…
ABSTRACT This research aims to utilize the rotation of a 12-inch Ventilator Turbine to drive a DC generator.
