Abstract

Electrical energy can encourage economic growth and public knowledge. However, electrical energy also has potential safety hazards if it is mishandled and used. We often hear in the mass media that fires occur due to short circuits or accidents caused by being touched by electric currents which cause injuries and even fatalities. This is because the electrical installation installers are not neat, causing electric current leaks and causing sparks and resulting in fires due to the electrical installation not being in accordance with reference standards. One of the efforts to help the government and the community in installing electricity on a household scale (Domestic), is to carry out Community Service activities at the mosque Al Falah which is located at the Al Falah 2 RT. 005 RW. 009, Pondok Benda, Pamulang, South Tangerang. The method used in this Community Service activity is to invite the community to come to the location where electrical installation repairs will be carried out. This is done so that people know how to install electricity and immediately practice it. The tools and materials that will be used to check and repair electrical installations at the mosque Al Falah include multimeters, test pens, current limiters, fuses, cables, insulation testers, conduit pipes and electrical insulation. The result of this Community Service activity is that the electrical installation at the mosque Al Falah becomes suitable for use in accordance with PUIL 2000.

Abstract

The intensity of lighting and air distribution in a room is one of the important parameters of a healthy room. Currently, there are still many rooms that do not have a proper level of lighting intensity and air distribution, especially for teaching and learning activities. Currently SMK Sasmita Jaya 2 has one room for teaching and learning activities which is still far from feasible with the level of lighting intensity being at 45 lux with room temperature reaching 30.4 °C. This will have an impact on the comfort in teaching and learning activities in the room. For this reason, it is necessary to increase the intensity of lighting and reduce the temperature level of the room by repositioning lighting installation techniques and adding an indoor air distribution system. So that the lighting intensity of the SMK Sasmita Jaya 2 room can be increased and the room temperature can be lowered. The results of the measurement of lighting intensity after repositioning the lighting installation has increased to 105 lux from the previous 45 lux and the room temperature has decreased by 1.6 °C from the previous 30.4 °C to 28.8 °C after the addition of an air distribution system. From the results obtained, it can be concluded that Community Service activities in Increasing Lighting Intensity and Air Distribution in Classrooms of SMK Sasmita Jaya 2 were successfully carried out by increasing the intensity of lighting and decreasing room temperature.

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.
