Abstract

In Indonesia Rosella Flowers are used as herbal tea. The process of brewing Rosella Tea is brew 3 – 4 dried rosella petals with 200ml hot water. This brewing process takes a long time from 10 minute or 15 minute. One of way to improved is crushing the rosella flower to little shape with apply PID method. This machine use Atmega32 as controller, speed sensor, laser sensor, and DC Motor as actuator. The working principle of this machine is to stabilize DC motor speed, effective procces is at 900 RPM, in this speed takes 07 minutes 15 seconds to finished the process, and laser sensor has not detected rosella flower to crushing the system will turn off automatically. With percentage overshoot  10.2 %,  settling time 245 seconds, and biggest error of speed sensor is 2.6 % . The reuslt from speed sensor will display at LCD 2*16 to make easily to analysis.

Abstract

Damage to the bridge resulted in disruption of the activities of residents who want to cross the bridge. Damage to the bridge is not only due to problems with the infrastructure but can also be caused by humans, one of which is due to excess capacity on the bridge so that the construction of the bridge cannot hold or accommodate many people resulting in the bridge collapsing and resulting in several fatalities. This research is expected to help reduce and prevent damage to the bridge structure by implementing a Load Sensor using the ESP8266 microcontroller. This system is based on the Internet of Things (IoT). Based on the research results, when the condition of the bridge has no visitors, the resulting weight is 0, the display on the serial monitor "No Visitors..!!,","LOADS ARE SAFE..!!". weight of 3 kg, display on the serial monitor "LOAD SAFE.. !!,", "Number of visitors = 5", "LOAD = 3.03 kg". , a warning will appear "Visitors Full = 10", "LOAD OVER", "Number of Visitors = 10", "IN = 10", "OUT = 0", "LOAD = 6.67kg" on the Serial Monitor. the number of visitors will decrease when visitors leave the bridge.
