This paper presents the design and implementation of amobile embedded system using an Arduino microprocessor to monitorand record key operational indicators of a distribution transformer,such as transformer oil level, temperature and vibration of adistribution transformer in a substation. If there is any abnormalityor an emergency situation, the system sends SMS (Short MessageService) messages to designated mobile telephones containinginformation about the abnormality of the mentioned parameters.Providing early warning of the abnormality of the distributiontransformer can be accomplished by shutting down the entire unitwith the aid on-line monitoring system integrates with Global ServiceMobile (GSM) Modem. Furthermore, the design generally consiststand-alone single chip microcontroller, modem and sensor packageslocated on distribution transformer site. In general, the design isdeveloped for the user to easily recognize the distribution transformerthat is suffered by any high vibration and rise in temperatures andlocated in remote or suburban area which is rarely and hard to reachfor manual monitoring. The ultimate objective is to monitor thetransformer oil level and temperature of 24 hours, 7 days a weekcontinuously besides the current and voltage parameter whichincluded in basis monitoring system

Most operators in industry use trial and error methodin determining the parameter in PID controller. This way isquite dangerous because it cannot predict what will happen inthe next process. For this, we need a method that can adjust thechanging of parameter in process, and simultaneously retune theparameter of controller automatically. Ziegler-Nichols method, amethod for setting parameter of PID controller, can be use foreliminating the oscillation and reducing overshoot curve in aprocess. This method is common yet, but it offers simpleprocedure but produce quick and accurate result. This methodanalyzes the curve of a process. It is done when oscillation andovershoot projected onto x-axis (time) occurred. The parametersresulted from this analysis among others are: critical gain (Kpu),time/period oscillation (Tosc), static gain (K), proportional gain(Kp), integral time Ti, and differential time Td. These parameterswill be tuned to PID controller using Ziegler-Nichols method.The overshoot (Mp) curve response of closed loop in thissimulation is 0 %. It will save energy and time beside that thestability of system can be maintained.

A dynamic two-phase imbalance mechanism model ofpressurizer in pressurized water reactor (PWR) nuclear powerplant was built based on some reasonable simplifications andbasic assumptions. The equations of energy and massconservation are used in obtaining a mathematical model forpressurizer operation. The pressurizer is divided into tworegions, steam region and liquid region but not necessary inequilibrium with each other. Considering the influence of thespray flow, surge flow, safety valve and heater, the model ofpressurizer pressure control system is established byMATLAB/Simulink in this paper. For the large overshoot,response delay and poor stability exist in the pressurizer pressurecontrol system, an advanced model based on PID controlalgorithm is proposed. The simulation results were comparedbetween two different data obtained by foreign PWR nuclearpower plant simulator. All the compared data are quite similar insimulation result, hence it proves the simulation result quiteaccurate and yet the mathematical model obtained has proved itsworking principles successfully.

The robot is a machine that can perform physicalactivity repeatedly, either with human control or worksautomatically with the use of artificial intelligence. In the process,the robot can perform various kinds of sports, one of which is abranch of football. Robot football match organized by theFederation of International Robot-Soccer Association (FIRA)consists of several categories, one of which Micro Robot SoccerTournament (MiroSot). MiroSot is five to five games consisting of arobot measuring 7.5 cm x 7.5 cm x 7.5 cm were able to move andadapt to the environment without human intervention. CurrentlyInformatics UPN "Veteran" Yogyakarta began to develop MiroSotbut there are still some problems found that the movement of therobot is irregular, so that frequent collisions of the robot opponent.So it takes a function to avoid obstacles on the robot MiroSot.Capitalize knowledge of Obstacle Avoidance of the book "SoccerRobotics" [1], the function of avoiding obstacles using the potentialfield based navigation univector algorithm to determine the futurepath of the robot and dodge the functionality tailored to thecharacteristics of the robot MiroSot Information Engineering UPN"Veteran" Yogyakarta.

Publisher : IAES Indonesia Section

This paper discusses about an observer based faultdetection scheme to detect sensor and actuator faultssimultaneously in LTI system. The proposed strategy is to addderivative action on the extended state observer (ESO) in additionto proportional-integral action, so that the structure of theproposed observer is PD/PI or called PD/PI-ESO. The derivativeaction is performed both in state estimation and fault estimation.This is to achieve fast state estimation as well as fast faultestimation. Furthermore, the effects of disturbance are attenuatedby using the H performance approach. The observer gains arethen determined based on Linear Matrix Inequalities (LMI)technique. Simulation results of a DC motor speed control systemare presented to illustrate the effectiveness of the proposed method.
