Abstract

Pencahayaan lampu dalam ruang rawat inap merupakan salah satu fasilitas rumah sakit untuk membantu proses penyembuhan pasien. Sesuai dengan Undang – Undang No.44 tahun 2009 pedoman teknis tentang fasilitas rawat inap adalah ruang dan fasilitas didukung oleh sistem pencahayaan lampu secara alami dan/atau pencahayaan buatan. Fasilitas fisik pencahayaan dalam ruang harus bersifat optimal sesuai dengan fungsi masing – masing ruang. Sedangkan pencahayaan buatan direncanakan dengan tingkat iluminasi dengan syarat pertimbangan efisiensi, efek silau dalam pantulan.Tujuan dalam penelitian ini mengatur intesitas cahaya lampu sesuai dengan kombinasi paruh waktu untuk menekan ketidaknyamanan pasien dengan metode sensor cahaya dan sensor suhu sebagai bagian dari perawatan dalam ruang menggunakan pengaturan secara mikrokontroler dan dimonitoring dalam database web server. Hasil dari ngujian sistem dari dua buah sensor yaitu sensor LDR dapat diatur pembacaannya dalam paruh waktu pagi sebesar 400lux, siang hari 200 lux dan malam hari 120 lux. Lampu ultraviolet digunakan hanya pada tingkat kelembaban ruang diatas suhu menggunakan sensor DHT11 yang sudah ditentukan yaitu rata-rata suhu 250C sampi 290C. Delay pengiriman data rata – rata sebesar 0.60 ms.

Abstract

The limitations of developing high-tech communication systems cause the area of people who can use this service to be uneven. One technology that can be used for areas not yet reached by this high-tech communication service is to use radio communication technology. Today radio communication technology continues to develop and produce an increasingly limited frequency spectrum. One way to improve the efficient use of available frequency spectrums is the transition from analog technology to digital technology. A very significant benefit in the use of digital technology is to save the use of radio frequency spectrum bandwidth with signal compression techniques. One device that still uses analog technology is a handy talky (HT). In addition to the lack of frequency spectrum efficiency, HT technology still requires a radio station license (ISR) for its use. This experiment designed a two-way digital audio communication system that was transmitted using the NRF24L01 radio frequency transceiver module on the 2.4Ghz frequency. Analog input data from the microphone will be converted into digital data through the ADC (Analog to Digital Converter) process using a microcontroller and the digital data that will be sent is first digitally modulated using GFSK modulation then transmitted digitally. On the other hand data that already contains voice information received again by another NRF24L01 transceiver is received by the Arduino microcontroller and then formed into a PWM signal (pulse width modulation) and then released to the speaker. So the method of using digital transmission can produce efficiencies in the frequency spectrum.
