Abstract

Traffic congestion and zebra crossing violations are common problems at road intersections due to fixed-time traffic light systems that are less adaptive to traffic conditions. This research aims to design and implement an ESP32 and Internet of Things (IoT)-based Smart Traffic Light system using the Mamdani Fuzzy Logic method to automatically regulate traffic light duration based on vehicle density. The system utilizes an inframerah sensor to detect vehicle density and an ultrasonic sensor to detect zebra crossing violations. Sensor data are processed by the ESP32 through fuzzification, inference, and defuzzification to determine the appropriate traffic light duration. The system is equipped with traffic light LEDs, a TM1637 countdown timer, a buzzer, and a Telegram Bot for real-time monitoring. Testing results showed that the inframerah sensor successfully detected vehicle density, while the ultrasonic sensor accurately detected objects at distances of 5–25 cm. The fuzzy logic system produced green light durations of 5, 20, and 30 seconds for low, medium, and high traffic densities, respectively. In addition, the Telegram Bot successfully sent real-time notifications of zebra crossing violations. The proposed system operates automatically, adaptively, and effectively to support traffic management and zebra crossing monitoring.

Abstract

: Fire is one of the most detrimental hazards to the community, therefore a fire prevention system is needed to reduce the impact and losses caused by fire. This study aims to design a fire protection system that has a high level of reliability, capable of detecting various types of fires, this study aims to find out whether the provision of equipment in building A of Universitas PGRI Palembang has met the requirements according to the technical requirements of the fire protection system in buildings and the environment according to the regulation of the Minister of Public Works No.26/PRT/M/2008. The planning of the fire protection system in building A of the University of PGRI Palembang includes, planning the detector system, sprinklers, fire alarms, water volume and pumps. The results of the planning of this fire protection system are 22 detector points, 50 sprinkler points, a water volume of 190 m3, a water tank volume of 164 m3, a pump power of 112 kW, and a GWT capacity of 92 m3.

Abstract

Housing employees of PT. Cipta Lestari Sawit Bumirejo Estate in block B55 is located in the middle of an oil palm planta- tion, so the state electricity company network cannot reach the housing. So, this housing uses a diesel power plant (PLTD) as a source of electricity, its operational hours are limited and it also causes noise and air pollution. From this problem, one suitable solution is to build a solar power plant (PLTS) that does not cause noise and air pollution and its operating hours can be adjusted as needed. In planning PLTS, there are main components that need to be calculated including Solar Panels, Solar Carger Controller (SCC), Batteries, and Inverters. For planning PLTS in employee housing block B55 PT. Cipta Les- tari Sawit Bumirejo Estate requires 273 solar panels with a capacity of 300 wp per unit, 53 solar charge controllers (SCC) with a capacity of 80 amperes, 34 batteries with a capacity of 2000 Ah per unit, and 68 units with a capacity of 6000 watts per unit. to supply electricity to 70 houses and 8 street lights.
