Abstract

Technological developments have opened up a new infrastructure in communication for transmitting audio data. This is evidenced by the large number of communication media, both wired and wireless. So that it raises new methods for sending audio data, one of which is using Visible Light Communication (VLC). VLC is a communication system for transmitting and receiving data using the visible light wave spectrum between 375 nm - 780 nm. In this research, audio data communication utilizes the brightness of the LED light. The transmitter and receiver use an LED component as a transducer which is then sent to the data processing circuit. From the data processing circuit then sent to the audio amplifier circuit. From the test results it can be shown that this system can transmit audio data. Based on the LED color test, Green produces the highest output voltage of 1.32 Volt. The angle limit that can be detected by the photo diode is at an angle of 70° with a measured voltage of 100mV and the resulting sound intensity of -32.541dB.

Abstract

Penelitian ini bertujuan untuk menganalisis kinerja UPS yang digunakan dalamsistem pencahayaan landasan pacu di Bandara Adisutjipto. UPS di Bandara Adisutjiptomemiliki kapasitas daya 140 kVA. Penelitian ini menggunakan metode survei lapangan,pengumpulan data operasional UPS, serta analisis performa berdasarkan data historis.Data hasil pemantauan dan pengukuran terkini digunakan untuk mengevaluasi total dayabeban, kapasitas baterai, dan runtime UPS dalam menyuplai ALS. Hasil penelitian yangdiperoleh bahwa UPS load di Bandara Adisutjipto Yogyakarta terpakai sebesar 14,09%(terpakai 19,734 kVA dari 140 kVA). Berdasarkan Hasil perhitungan ini berarti masih dapatdilakukan penambahan beban atau server yang lebih banyak lagi. Berdasarkan perhitunganUPS rating ideal, UPS di Bandara Adisutjipto Yogyakarta memiliki daya yang lebih besar dariUPS rating ideal (oversizing UPS). Ini dilakukan untuk mendapatkan runtime yang lebih lamadan untuk mengantisipasi bila ada penambahan server. Berdasarkan nilai daya terpasangsekarangdengan beban yang digunakan pada Airfield Lighting System, UPS ini mampumendapatkan runtime selama 6 jam 50 menit ketika suplai pasokan listrik PLN mengalamigangguan.
