Abstrak-Pembangunan infrastruktur saat ini lebih berfokus pada pembangunan jalan raya, meliputi jalan bebas hambatan (TOL). Pertumbuhan pembangunan jalan raya berbanding lurus dengan penambahan lampu penerangan jalan umum (PJU) di berbagai ruas jalan raya. Hal ini membuat konsumsi energi listrik untuk penerangan jalan semakin besar. Penggunaan jenis lampu LED dan penambahan fitur dimmer untuk penerangan jalan raya menjadi solusi untuk mengurangi konsumsi energi listrik. Penelitian ini secara

... sus menganalisa emisi konduksi yang dihasilkan oleh lampu LED penerangan jalan umum yang dilengkapi dengan fitur auto dimming. Penelitian ini menggunakan dua kelompok lampu LED peneragan jalan umum (PJU) yaitu lampu PJU dengan auto dimming dan lampu PJU tanpa dimming. Tujuan yang ingin dicapai pada penelitian ini adalah mengetahui konsumsi daya dan emisi konduksi lampu LED PJU dengan dimming dan tanpa dimming. Metoda pengujian mengacu pada CISPR 15 yaitu mains terminal disturbance voltage. Konsumsi daya listrik lampu LED PJU dengan dimming lebih rendah jika dibandingkan dengan lampu PJU tanpa dimming. Konsumsi daya lampu LED PJU lebih rendah ≤ 8% jika dibandingkan dengan lampu PJU tanpa dimming. Semua lampu LED PJU dengan dimming memenuhi persyaratan uji emisi konduksi pada terminal utama pada CISPR 15. Pada lampu LED PJU tanpa dimming terdapat 2 buah lampu yang tidak memenuhi persyaratan uji emisi konduksi pada CISPR 15.

Growth in road construction is directly proportional to the addition of public street lighting on various highway sections. This makes electricity consumption for street lighting even greater. The use of LED lights and the addition of dimmer features for street lighting are solutions to reduce electricity consumption. This research specifically analyzes the conduction emissions produced by LED street lights, which are equipped with auto dimming features. This study uses two groups of public street lighting LED lights, namely Public Street Lighting with auto dimming and Public Street Lighting without dimming. The aim of this research is to know the power consumption and conduction emissions of LED Public Street Lighting lamps with dimming and without dimming. The testing method refers to CISPR 15, namely mains terminal disturbance voltage. The power consumption of Public Street Lighting LED lamps with dimming is lower compared to Public Street Lighting lamps without dimming. The power consumption of Public Street Lighting LED lights is lower ≤ 8% compared to Public Street Lighting lamps without dimming. All Public Street Lighting LED lamps with dimming meet the conduction emission test requirements on the main terminal at CISPR 15. On the Public Street Lighting LED lights without dimming there are 2 lamps that do not meet the conduction emission test requirements on CISPR 15.
