This research develops and tests an innovative tool called ASLA (Automated Signal Light Brightness Adjustment) designed to automatically adjust the brightness of train signal lights based on environmental conditions such as light intensity, rain, and fog. The main purpose of this tool is to reduce the waste of electrical energy caused by using lights with constant brightness all the time. An experimental method is used in this research, where tests are conducted by measuring important variables such as light intensity, current, voltage, and LED brightness. It uses sensor fusion techniques to combine data from various sensors, such as LDRs, rain sensors, and gas sensors, to obtain accurate environmental information. The test results showed that the ASLA tool successfully reduced power consumption from 2.37W to 2.24W, contributing to electricity savings. In addition, the variation of LED power decreased to less than 0.2W under certain weather conditions. This research proves that ASLA functions optimally by increasing the efficiency of electrical energy use in train signal lights.

Based on the research conducted, the ASLA (Automated Signal Light Brightness Adjustment) device has been successfully developed and tested to automatically adjust the brightness of train signal lights based on environmental conditions.The tool effectively reduces electrical energy waste by optimizing light intensity according to factors like light intensity, rain, and fog.The experimental results demonstrate a successful reduction in power consumption, averaging 2.3W with LED power variations between 0.

Penelitian lebih lanjut dapat dilakukan untuk menguji efektivitas ASLA pada berbagai jenis lampu sinyal kereta api dan kondisi lingkungan yang lebih beragam, termasuk variasi geografis dan iklim. Selain itu, studi komparatif dapat dilakukan untuk membandingkan kinerja ASLA dengan sistem pencahayaan sinyal konvensional dalam hal penghematan energi, keandalan, dan biaya perawatan. Pengembangan sistem ASLA yang terintegrasi dengan sistem kontrol kereta api secara keseluruhan juga dapat dieksplorasi, memungkinkan penyesuaian pencahayaan sinyal secara otomatis berdasarkan jadwal kereta api dan kondisi lalu lintas, sehingga meningkatkan efisiensi operasional dan keselamatan kereta api secara keseluruhan. Penelitian ini diharapkan dapat memberikan kontribusi signifikan dalam pengembangan sistem pencahayaan sinyal kereta api yang lebih cerdas, efisien, dan ramah lingkungan.
