Abstract

The Organic Bin Recycler machine is designed on a small scale to be placed in the kitchen and functions as a special trash can for organic waste. The design of this machine aims to reduce the problems related to the disposal of organic food waste and kitchen waste, reduce environmental pollution, and to produce compost. Composting in this machine is done by adding a bioactivator. The design is carried out with the catia v5 software in accordance with the calculations that have been done. The machine has two main components, the organic waste crusher, and the waste stirring component. The crusher uses an electric motor with a power of 0.75 kW or 1 Hp with a rotation of 1400 rpm. The stirring component uses a motor with a power of 0.18 kW or 0.245 Hp and a rotation of 1400 rpm which is reduced to 30 rpm using a 1:20 reducer gearbox. The transmission system used is a belt and pulley transmission.

Abstract

The need for electrical energy is increasing along with technological advances. In addition to the large population in an area, the variable economic activity of the population, which continues to increase to meet their daily needs, also has an impact on increasing the need for electrical energy. Demand for electrical energy is in line with increased economic activity. Therefore, developing renewable energy to provide sufficient electricity supply is very important. In this research, the modeling of a Micro Hydro Power Plant (PLTMH) has been designed using a breast wheel with a semicircular blade shape, a wheel diameter of 20cm, and 10 blades. The wheel model has 5 variations of water level (head) calculated from the water level in the reservoir to the water level in the wheel with 3 variations of ball valve openings. It was observed that the highest efficiency is at a head height of 0.8 m with a pipe cross-sectional area (A) of 0.0002 m2 with an efficiency of 70.11 percent. The increase in the flow rate of water flowing towards the breast wheel turns out to cause the wheel rotation to decrease. The decrease in the wheel's rotation is related to the increase in turbulence (collision) due to the large discharge of water against the wheels' walls. It can be concluded that the combination of gravity and water propulsion can move the breast wheel so that it produces electrical energy.
