Abstract

This study aimed to determine the community's attractiveness in managing waste in Jombong Hamlet, Patent, Dukun, and Magelang. This activity aims to reduce the accumulation of household waste so that there is no disaster and to utilize the waste with the creations and innovations of the surrounding community. The methods used are observation, interviews, and documentation. With the PAR (Participatory Action Research) approach, the service team views the existence of a waste bank as an essential asset for the community. The results show that waste bank management benefits the surrounding community; the environment becomes comfortable, beautiful, and green. This study concludes that household waste can benefit from the social, economic, and environmental aspects that positively impact the Jombong Hamlet Waste Bank.

Abstract

This research aims to design an automatic helmet dryer that uses PID-based temperature control to maintain a stable temperature at a setpoint of 45°C, especially in rainy season conditions that often make helmets wet and damp. A damp helmet has the potential to become a breeding ground for fungi and bacteria, as well as causing unpleasant odors and health problems. This tool controls the temperature using a PID controller with a BTS7960 driver module with temperature readings from a DHT22 sensor. The Ziegler-Nichols tuning method produces initial constant values Kp=7.64, Ki=0.1273, and Kd=114.6, but fine tuning is required to achieve the best constants Kp=100, Ki=1, and Kd=114.6. The test results show that the open face helmet can dry in 68 minutes with a final humidity of 38.9%, and the system response was 1,1% overshoot, 0 °C steady-state error, 246 seconds rise time, and 561 seconds settling time. Keywords: PID (Proportional-Integral-Derivative), Helmet Dryer, Ziegler-nichols.
