Abstract

Energy consumption is increasing day by day and is very focused on the use of fossil energy, or better known as fossil fuel, which is now decreasing in number and the price is certainly more expensive. On the other hand, there are various types of renewable energy available, abundant in number and of course very cheap and non-polluting, including water energy, solar energy, biomass energy, wind energy, and it is usually called renewable energy. be used as a priority to accompany or replace the use of fossil fuels. This energy research is carried out to avoid energy scarcity in the future. Through the development of energy conversion machines, renewable energy can be utilized optimally in Indonesia for energy needs to support human needs in the energy sector. Renewable energy that is very close to us, we even feel it every day is wind energy, and in coastal areas there is a lot of potential for wind to use wind energy. This potential can be developed through the use of windmills. One form of windmill that is easy to make is the Sovanius windmill. The advantage of this windmill is that it can make initial rotations with low wind gusts.

Abstract

Using solar energy as a source of electricity has great potential. A boost converter is needed to overcome the low energy conversion efficiency of solar panels. Many boost converters have been used to achieve high efficiency, one of which is the quadratic boost converter. This study aims to increase the efficiency of solar panel output at low inputs. An overall study of the system with a lamp load of 2 volts from 09.00 WIB to 15.00 WIB showed that the highest efficiency was achieved at 10.15 am at 99% with an average efficiency of 80%. At the same time, the output voltage is 24.64 volts. From the voltage and current obtained simultaneously, the input power is 2.99 watts and the output power is 2.97 watts. From the tests I did, it appears that the quadratic boost converter can provide a fairly high output voltage. Low-duty cycles have been shown to produce higher output voltages than traditional boost converters.

Abstract

The number of traffic accidents in Indonesia is increasing. One of the main factors causing an accident is the driver's drowsiness. In general, drowsiness appears at night when the body needs rest. However, some of them appear due to fatigue during activities, situations like this need to be considered when we are driving so that the number of accidents caused by drowsiness can be avoided. From these problems, we need a tool that can automatically detect whether the car driver is sleepy or conscious using a facial landmark method. Where in the early stages it starts with taking pictures using the Raspberry Pi camera which will be processed by the Raspberry Pi 3b to detect facial areas using the eye aspect ratio then the algorithm on the eye aspect ratio is used to detect sleepy eyes with the output in the form of speakers and water pumps, where the speakers will emits a sound that can be changed according to the wishes of the driver. After the speaker sounds, the water pump will spray water on the face to react so that the driver doesn't get sleepy.
