Abstract


Pencurian listrik menyebabkan kerugian negara, karena daya akan hilang dan rusaknya infrastruktur jaringan listrik. Pada umumnya pencurian listrik dilakukan dengan cara mem-bypass ECB (Electronic Circuit Breaker), sehingga daya listrik yang digunakan bisa melebihi batas. Pada penelitian ini, telah dirancang sebuah sistem monitoring arus listrik jala-jala menggunakan Power Line Carrier (PLC). Sistem ini dapat mengetahui penggunaan arus listrik distribusi rumah tangga, sehingga jika ada penggunaan arus litrik jala-jala yang berlebih, maka dapat diindikasikan pada line itu terdapat kemungkinan pencurian listrik. Sistem terdiri dari transmitter dan receiver. Jala-jala dipilih sebagai media komunikasi data karena jaringan infrastruktur instalasi pendukungnya yang sudah ada. Berdasarkan pengujian pengukuran arus listrik jala-jala dengan beban yang beragam, didapatkanrange toleransi pengukuran arus sebesar 0 - 11%. Pengiriman data arus dari transmitter menuju receiver menggunakan komunikasi serial dengan kecepatan pengiriman 300 baud. Jarak komunikasi data melalui media jala-jala mencapai 31 meter dengan tingkat keberhasilan pengiriman 100%.
