Abstract

Electricity is one of the basic needs of modern human life and is already so integrated into everyday life. This is understandable given the coal's ample resources. Another factor that influences the growth of coal use is that coal plants are designed asa basic burden because the price of coal is relatively cheaper. However, coal's existence as fuel for power plants is on the decline and is not renewables. One of the applications of renewable energy potential is solar power generation technology. On this system using solar panels using 30 wp power. Solar dependence on the environment affects the change in output values in hybrid plant systems, resulting in easy damage to both domestic and industrial appliances or in battery storage systems, so a mechanism is needed to stabilize the output voltage supplied to the battery or load. So, out of this renewable energy potential, it creates innovation Implementation of Voltage Stabilizers on Solar Cell System Using Buck-Boost Converter. Aided by current and voltage sensors controlled by arduino uno so that they can insulate input and output from buck-boost converter. Results from the testing of this device indicate that the buck-boost converter is able to stabilize output output from solar panels with a 14.4 volt set of points. The average efficiency obtained at buck-converter converter testing at buck mode is 85.4 %. On boost mode is 80%. On buck-boost mode is 79.2%.

Abstract

The dolly camera has function as a regulator of camera movement in making video productions such as films. The movement system on the dolly camera uses the thrust of humans and the running track rail for its movement. The process of preparing the dolly camera also requires a long process, such as assembling the dolly camera and then installing the track, etc. In this case study, we conducted research that designed an electric vehicle to carry a camera but with a simple way of working such as moving without rails and can be controlled with a mobile android. We named this robot vehicle ELDOC: Electric Dolly Camera which uses a four Omni-direction wheels system in the flexibility of direction and motion for taking videos and pictures. Contributions to the design of ELDOC in addition to the multimedia/cinematography field can also be used in the medical field as a monitoring tool for patient activities in isolation or ICU room with a mobile android from different rooms. In the results of the process running on the motor, we take error data from the calculation speed and measurement speed, wherein the duty circle is 19.60%, 38.50%, 58.8%, 78.66%, and the average error is 0,08. The stability level of the ELDOC when carrying the camera is stable but has vibrations or oscillations. The results of the data orientation (gyroscope) show the total average of the three samples Y (Roll) orientation is 0.6°/s and X (Pitch) orientation is 0.18°/s.
