Information system is a set of components that interconnect, collect, process, store, and distribute information to support decision making and supervision within an organization. Today the information system can not be separated with computer technology that feels growing rapidly along with our increasingly complex needs. These developments can be seen from the many organizations or institutions in various fields that use computerized systems to perform various jobs quickly and with great accuracy. The use of computerized systems is expected to minimize errors made by humans thereby reducing large losses. And can mengefisienkan time in completing the work quickly and accurately. One concept of building a computerized information system is dengfan MVC model. Model-View-Controller (MVC) is a concept introduced by the inventor of Smalltalk (Trygve Reenskaug) to encapsulate data along with processing (model), isolate from the process of manipulation (controller) and view to be represented on a user interface . The MVC architecture has the benefit of separating between model and view allowing multiple views using the same model. As a result, an application model component is easier to implement, test, and maintain, because all access to the model runs through this component. One of the frameworks that works based on the MVC concept is Codeigniter. Codeigniter is an open source web application framework that is used to build dynamic php applications. The main purpose of Codeigniter development is to help developers to work on applications faster than writing all the code from scratch. Because of the superiority of codeigniter that the system of practical work administration and the final task is built using the framework..

The realization of the On-Off control system can be built using the comparator principle. The principle has a weakness that is the possibility of chattering due to 'thin' limit of comparator switching. Low immunity to noise increases chances of chattering, if not anticipated it will cause 'fatigue' on actuator thus reducing componentâ€™s lifetime. Hysteresis has features to suppress chattering. This article describes how to realize the hysteresis On-Off controller using Operational Amplifier (Op-Amp) which is simple and cheap discrete electronics component, by modifying the Op-Amp comparator circuit so that it has the hysteresis band with minimum and maximum limit variable so that the reference point of the comparator can be shifted.

Internal temperature of electric panel practically depend on the amount of power dissipation generated by the panel components and the outside temperature. If this equilibrium is not maintained then the internal temperature can increase too high beyond the working temperature limit for components so as to shorten the life of panel components. Generally, there are two fans installed to circulate the air inside the panel that operates atÂ fixed speed. In order to improve fan energy efficiency, it is necessary to add a control system that can adjust the fan speed based on actual panel internal temperature. Efforts to increase energy efficiency are realized using cheap hardware and easily available on the market, the ATMEGA 8535 microcontroller and LM 35 temperature sensor. The fan speed is normalized in percent units and expressed virtually using the Pulse Width Modulation (PWM) signal value calculated by the proportional control algorithm inside the controller. The experimental results show that the PWM value can vary with actual panel internal temperature. Using the time constant temperature asumption k1 = 0.2, k2 = 0.4, k3 = 0.2, k4 = 0.2 and experimental data, it was shown by calculations that there was an increase in energy efficiency by 40.8%.

The identification system is a procedure to obtain a model of a system, then of the model will be validated to see the accuracy of the model is obtained, compared to the input-output results obtained from the experiments. In the identification system itself known two methods, the method of "non-parametric" and "parametric". On the other hand, DC motor is a type of motor that uses direct electric current to produce rotational mechanical energy and is widely used in various applications. In this study, input and output data acquisition will be performed on the Feedback brand DC motor, and the data will be processed so that the system model is obtained by the black box method. The data will then be processed with the help of MATLAB software. The input signal used in this experiment is Pseudorandom binary sequence (PRBS), which is used because it has a wide frequency range. The signal is generated by an arduino uno microcontroller. From the test results it was found that the validation of the non parametric system model with the correlation analysis method has a fitness value of = 83.19%, while the validation of the parametric system model with the least square ARX method has a fitness value of = 80.59%.

RANCANG BANGUN SISTEM RACK IN DAN RACK OUT PMT OTOMATIS DI KUBIKEL 20 KV BERBASIS ARDUINO MEGA 2560 MENGGUNAKAN VTSCADA 11.2 Puteri, Ratna Azizah; Subari, Arkhan; Tadeus, Dista Yoel

The 20 KV PMT (Circuit Breaker) is an important equipment for the reliability of electricity distribution. Therefore it must be maintained so that it is always in good condition with regular maintenance. Prior to maintenance, PMT is terminated from the bus bar, which is called the rack out process. After maintenance, the PMT is reconnected with the bus bar, which is called the rack in process. Usually, 20 KV PMT rack in and rack out process in maintenance or disturbance is still using the manual method. The 20 KV PMT can only be racked in and racked out in one way, by turning the lever. The lever will rotate the bolt as a PMT rail. In the manual method, there is no system for monitoring the condition of the bus bar whether it is has electric-voltage or not. There is also no remote control that can rack in and rack out. So officers must ensure the conditions of PMT and bus bars are safe manually, before maintenance is carried out. This is quite troublesome and dangerous for officers. From these problems, in this research Â designed a system that could ensure the condition of the PMT and the bus bar was safe before the rack in and rack out process was carried out and could monitor and control the system remotely using SCADA. Rack-in and rack-out automation system using VT SCADA, using Ethernet Shield that has been connected with Arduino Mega. Ethernet is connected to a mini PC. The microcontroller pins will be connected to the relays that will turn or stop the motor. The rack in and rack out commands from VT SCADA will determine the rotation of the motor so that the PMT moves. The current sensor reads the current flow and detects interference. Interference detection will automatically make PMT Rack out. System testing shows that the process of racking out in a state of maintenance or disturbance can be carried out automatically controlled by VT SCADA. Current sensor works to detect the current flowing, so that it can detect PMT interference and perform automatic rack out. The rack-in process is also capable of being remotely controlled with VT SCADA. This makes it easier for officers to also become additional reliability of PMT in the 20 KV cubicle.
