Pengembangan Transmisi Daya Listrik Menggunakan Cahaya Laser dengan Fiber Optik untuk Peralatan Kebencanaan di Daerah Remote

Abstract

Natural disaster monitoring instruments as an integrated early warning system had been widely developed and placed in areas that were estimated to be prone to natural disasters. This was done to help the government and the public take pre-disaster and post-disaster actions to reduce losses experienced. However, the placement of these monitoring instruments had many shortcomings, one of which was the theft of the main component of the battery or battery which was a power source to activate the instrument. An alternative technology was used to overcome this problem, namely by relying on power transmission with fiber-optic-based laser light. Laser light will be sent to the location using optical fiber which was then emitted to the solar panel so that the laser light was converted into electrical energy. The power generated by solar panels illuminated by 810 nm laser with an input power of 140 mW was 7.76 mW. The power that must be given to an 810 nm laser to produce the same power when solar panels were illuminated by the sun was 12,743 W. So, laser light transmission with fiber optic media as an alternative to providing energy sources in disaster monitoring instruments can be used to reduce losses
