Abstract

Visible Laser Light Communication System (VLLC) is a wireless communication system, using laser as the medium. In the data transfer process, it is possible to have optical interference where 2 laser beams coincide with one point on the reflector. Research on the effect of laser source interference has been carried out by several researchers including mitigation actions to reduce its effects. This experiment uses 2 optical distance sensors that produce a laser with a wavelength of 650 nm with a power <=4.1 mW and with the direction of the laser beam both of them cross each other. To determine the effect of the interference of two laser beams when crossing the communication process in the visible light communication system, a reflector is used which can capture the two laser beams and the reflector can be shifted gradually so that a condition can be obtained where the two laser beams meet at one point. From the measurements made at the points after the laser beam crossing, the measurements at the point where the beam crossed, and the measurements at the points before the beam crossing, it was obtained data, at the exact point where the laser beam crossed the interference occurred, which is indicated by unstable output voltage of the two lasers, so that communication at the point of intersection is disrupted. However, if outside the point of contact both before and after the point of contact, interference and communication systems will not occur.

Abstract

The use of electrical energy in the industrial is very important to drive production machines. Machine maintenance is carried out so that the lifetime of the machine becomes longer so that the production process continues. Temperature is one of the most common indicators of the structural health of equipment and components. This means that the main symptoms of damage to machines and equipment can be indicated by increasing the temperature of the equipment. One of the symptoms of an increase in equipment temperature is due to a loose cable termination. The use of infrared thermography to measure the temperature rise due to loose termination is one of the methods in electrical machine maintenance. Previous studies using infrared thermography to measure the temperature rise due to loose termination have been carried out by many researchers, but these studies did not show a correlation between the level of loose termination and the increase in temperature but only stated that the loose termination caused an increase in temperature. This study focuses on finding the relationship between the level of loose termination compared to standard torque and the increase in temperature at the termination point. This is very useful as a quick overview in determining the level of urgency in maintenance activity, that percentage of loose termination of a certain value below the standard will give an increase in temperature of a certain value as well. This study resulted, for the torque setting condition 67% below the standard (loose) the temperature increase at the terminal was 13.4% - 15.6%, for the torque setting condition 33% below the standard temperature increase at the terminal of 12.3% -13.8% which mean that the increase in temperature is directly proportional to the level of slack termination and is also directly proportional to the increase in the motor speed. If the termination torque level is lower and the motor speed is increased, the terminal temperature rise will be drastically rise.

Abstract

Public street lighting (PJU) is an infrastructure that supports community activities at night, as lighting for pedestrians and vehicle users, so as to improve driving safety and comfort, improve environmental security and prevent crime. The existence of PJUs that are not controlled, such as forgetting to turn them off until noon is often the cause of the high consumption of electrical energy. This is often ignored by the public and is considered normal, even though when viewed from the total national energy consumption it has extraordinary consequences. Saving electricity consumption is a solution to the problems faced by the community, with the manufacture and installation of an automatic PJU light control system. The purpose of this PJU lamp automatic control system is to make it easier to operate PJU lamps so as to reduce electrical energy consumption. The stages of implementation in Community Service are a solution to problems by making direct observations to the location to find out the components needed, designing control systems, procuring tools and materials, assembling control panels, installing and testing automatic control systems, providing education to the community. of the importance of controlling the consumption of electrical energy by not neglecting the safety and security of electrical hazards by applying standardization in the use of electrical equipment. The expected results in this Community Service, apart from providing safety and comfort, increasing environmental security and preventing crime as road users, can also provide public understanding and concern for energy saving, safety and security in using electricity.
