Abstract
Sebagai pengelola, Pemkot bertanggung jawab dalam hal pemeliharaan dan perbaikan infrastuktur Penerangan Jalan Umum. Banyak masalah pada PJU, seperti, kesulitan mendeteksi kerusakan lampu yang menyebabkan lambatnya respon perbaikan dan perawatan PJU. Solusi mengatasi permasalahan tersebut adalah penggunaan Internet of Things untuk pemantauan PJU yang terintegrasi jaringan internet.
Alat ini menggunakan NodeMCU ESP8266 12E sebagai kontroler beserta modul Wi-Fi, yang memproses data ADC yang didapat dari sensor arus ACS712. Melalui koneksi Wi-Fi, data arus ditransfer ke web server untuk ditampilkan data-datanya, dan dapat dipantau pada halaman web melalui smartphone bahkan laptop dengan mengunjungi alamat IP. Jika terdapat lampu yang mati, maka akan dikirim E-Mail berupa pesan dari status lampu mana yang mati.
Bedasarkan hasil akhir pengujian, modul Wi-Fi NodeMCU ESP8266 memiliki jarak jangkauan 300m ke access point. Data sensor arus ACS712 pada halaman web diperbarui tiap 1 detik. Pengiriman E-Mail rata-rata memiliki waktu delay sebesar 3,25 detik. Dari 10 kali pengujian pengiriman E-Mail, semuanya berhasil terkirim, maka tingkat error sebesar 0%. Data pembacaan sensor arus ACS712 memiliki rata-rata error sebesar 4,13%. Data sensor LDR pada nilai ADC 0 - 48, menunjukkan Lampu OFF. Untuk nilai ADC 810 – 1024, menunjukkan Lampu ON.
=========================================================
The Government shall be responsible for the maintenance and the repair of infrastructure public street lighting. Much of the problems at public street lighting, like, trouble detecting broken lamps of public street lighting, which causes the slowness of response repairs and maintenance of public street lighting. One solution to overcome these problems is the use of the Internet of Things to monitor public street lighting has integrated internet network.
This tool uses the lamps measured using light sensor ACS712. NodeMCU ESP8266 12E as controller and Wi-Fi module, which process ADC data obtained from the sensor ACS712. Via Wi-Fi connection, data flow is transferred to a web server to display the data, and data monitored on a web page through a smartphone even laptops, with visiting IP addresses are detected. If there are lights that are off, then it will sent an E-Mail that indicate the status lights which are dead.
Based on the final tests, the NodeMCU ESP8266 Wi-Fi module, has a 300 metre range to the access point. The data of current sensor ACS712 updated every 1 second on web pages. The delivery of the E-Mail has an average time of delay amounting to 3.25 seconds. On testing the mail delivery, with 10 times of the, everything is successfully sent, the error rate is 0%. Current sensor ACS712 reading had average error is 4,13%. Data sensor LDR on ADC value aroud 0 - 48, shown Lights OFF. For the ADC value around 810 – 943, shown Lights ON.
