Abstract

Traffic congestion is still a serious problem in many big cities in Indonesia, one of which is due to traffic light settings that are less adaptive to vehicle conditions on the road. This research aims to design and analyze the performance of an adaptive traffic light control system with image segmentation and pattern matching techniques using NI myRIO. The tests include selecting the optimal resolution, comparing fps with webcam input and AVI video, determining the best camera angle, and testing the system in bright, dim, empty streets, and early morning conditions. The results showed that a resolution of 176 × 144 and a camera angle of 90° provided the best performance. AVI video can be used as an alternative in system testing as the results are similar to webcam. The system performed optimally in bright conditions with an F-1 Score of 79.33% and a match rate score of 100% with an average fps of 9.93 fps. However, in dim conditions the performance decreased with an F-1 Score of 69.33% and a Match Rate Score of 41.67% with an average of 10.25 fps. In empty streets and early morning conditions, the system can still operate but sometimes experiences processing delays.

Abstract

The Energy Efficiency Index (EEI) records a building's performance and provides a baseline for energy consumption. Analyzing a power system using EEI involves total energy consumption, electricity consumption for each zone, and energy consumption distribution. This study aims to determine the electrical load profile and building profile of electrical energy consumption at Hotel Asri, analyze the performance of electrical energy use, and provide optimization conclusions. The electrical load profile includes installed loads (computers, TVs, hairdryers, refrigerators), cooling loads (Air Conditioning), lighting loads, and other loads (pumps, water filters). Hotel Asri's building area is 3446 m2, with an average total electrical energy consumption of 39.98967 kWh per year. After measuring Light Intensity and calculating installed and cooling loads, the IKE calculation for buildings with air conditioning is 7.8 kWh / m2 per month (highly efficient) and without air conditioning is 1.19 kWh / m2 per month (highly efficient). The IKE of the entire Asri Hotel building is 139,225 kWh/m2 per year, below the IKE target for hotels. Although Hotel Asri's IKE is highly efficient based on Indonesian building standards, many lighting measurements do not comply with the Indonesian National Standard for artificial lighting (SNI 03-2496-2001).
