Jatilawang – As we know, technology is developing very quickly. This can be seen from the emergence of very sophisticated tools. Apart from that, there is also the emergence of new renewable energy sources (EBT), one of which is solar energy.
Nowadays, global warming is caused by excessive energy use or exceeding its capacity. Excessive energy use has a negative impact on survival. Energy consumption in Indonesia is very large. Effective use of electrical energy is one way that can be taken to reduce or save electricity costs.
To save costs, use solar panels as a substitute for commercial electricity sources from PLN using solar thermal energy. The working system of this device is that the sun’s heat will be absorbed by the solar panels and will be stored in the battery which will then turn on the lights, then to turn the lights on and off automatically, it will use an LDR sensor and a light sensor.
Therefore, the KKN group of Universitas Diponegoro students, namely Jeremia Haganta S Kembaren from the D4 (Bachelor of Applied Science) Automation Engineering Technology program, applied the use of solar panels as an energy source to turn on the lights around the school at SDN 01 Jatilawang. This KKN work program first began with a request for permission and discussions with Principal of SDN 01 Jatilawang and Field Supervisor.
Followed by tool design and tool production. The process of making the tool consists of looking for suitable design references, looking for tools and materials that will be used to assemble the solar panel-based lighting tool.
This program aims to design automatic lights utilizing solar energy using a light sensor as a sensor. The program implementation method consists of 4 stages, the first is survey, the second is design, the third is programming and the fourth is testing. The school environment at SD Negeri 1 Jatilawang does not yet have adequate lighting. It is felt necessary to add lighting to several areas of the field to improve lighting at night to improve school security. Solar panel lights are the answer to getting lighting independently without burdening the school’s electricity usage, and the installation process is easy. It is hoped that the use of renewable energy can be a solution and support schools to become energy-friendly schools.
