Abstract

Generally, earthquake is measured with a seismometer, a device which is also known as seismograph  that works based on  detection of seismic wave in earth’s crust.  This research designs and implements an earthquake detection using frequency modulation method based on personal computer.  The research results a system and simulation. Simulation shows that in a normal condition the strength carrier is 2,5 % and before the earthquake occurred, the strength carrier is 55%. Frequency modulation method can be implemented  to detect earthquake by building some measurement stations at several   places.Keyword : earthquake, frequency modulation, seismograph

Abstract

PID control has been widely used in industry  as well as been implemented in the control of the liquid level . The research objective is to design  PID controller base on microcontroller  and then apply it on the miniature hopper-conveyor plant to maintain solid levels of raw materials to remain constant . The dimension of hopper is 25 cm long, 20 cm wide and 25 cm high. The design of PID control uses a separate action based on microcontroller and for the  tuning uses open-loop Ziegler-Nichols. The design is implemented in miniature hopper-conveyor plant to move the raw material form of green beans to the hopper using a screw conveyor. The screw conveyor is  rotated by a three phase induction motor with inverter speed drive. Level in the hopper is measured by using an ultrasonic sensor module build-in the data acquisition program . The experimental results of implementation on the miniature hopper-conveyor plant shows that PID control provides good performance such as overshoot occurs in  1 cm, or 0.05 % of set point and risetime shows 280 seconds. Key words: PID controller, microcontroller, Ziegler-Nichols, Hopper-conveyor plant

Abstract

Generally, point to point communication and broadcasting uses VHF band, each function VHF band can use for observes   activities at ionosphere. This research designed and realized   propagation detection use frequency modulation based personal computer.  Results of the research are realization of system and simulation. Simulation results   before ionosphere reflection occur is  50 % and after ionosphere reflection occur is 90 %. Frequency modulation method can be implemented   earthquake detection with realized measurement stations. Keyword : VHF, Propagation, ionosphere
