Abstract

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 component?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.

Abstract

Pandu Wicaksana, Saiful Manan, in this paper explain that the load balance on the 3 phase 4 wire distribution system is very important. Continuous load imbalances can cause a decrease in the reliability of the electric power system and the quality of electrical energy. One consequence of an unbalanced load is the presence of a current flowing in a neutral introduction. The purpose of this study is to find out and analyze the current in a neutral conductor when the load conditions are unbalanced and when balanced. Load balancing is done by manual-remote, which means that the transfer of taping at a load is done by pressing the button that has been integrated with the HMI display. This software is also responsible for displaying current output from the sensor. That way, it can be seen that the current value of the neutral conductor before and after load balancing is done. That the current value of the neutral conductor will be smaller when the load is balanced compared to when the load between phases is not balanced.

Abstract

Bima Dicky Anugrah Dewantara, Saiful Manan, in this paper explain that Electromagnetic retarders are generally known as electromagnetic inhibitors or brakes, the braking system eliminates most braking mechanics, thereby reducing conventional braking systems. Safety requirements and safety systems are developed and become a focal point of an equipment. Electromagnetic brakes are a safety component with a control system that is easy to control. With this electromagnetic brake, it will reduce maintenance costs, because it only requires a factor of electricity to be able to move it. The braking system uses electromagnetic forces to slow down a movement, which is generally a shaft motion. A dish with non-ferromagnetic metal material is attached to a rotating shaft. The disk is flanked by the side of the stator in the form of an electromagnetic coil system that can generate a magnetic field from electricity. Electric current generates a magnetic field in the coil. And the metal plate that cuts the magnetic field will cause eddy currents on the disk itself. This eddy current will generate a magnetic field whose direction is opposite to the previous magnetic field, thus inhibiting the rotary motion of the shaft. In designing, experimenting and making an External Electromagnetic Retarders System Design on 1 Phase Motor, use the NE 555 IC as the control duty cycle. So that the relationship between braking current and braking time is inversely proportional if the higher the current, the shorter the time it takes for the rotor to stop. And the relationship between braking current and motor current is directly proportional, by increasing the braking current will increase the load on the motor causing the motor current to increase. Keywords: Electromagnetic Retarders, Electromagnetic Brakes, Eddy Flow EffectReferencesTipler, P. 2008.

Abstract

Arkhan Subari, Saiful Manan, in this paper explain that most electronic equipment is non-linear load. Likewise with the equipment in campus buildings Diploma III Faculty of Engineering. Non-linear load is a load that has a voltage waveform supplied from non sinusiodal although sinusoidal voltage. Non-sinusoidal wave causes the shape of the voltage becomes distorted or defects that result in decreased quality of power. The defect wave called harmonics. To dampen harmonics on non-linear load can be used filter. With the addition of a filter on the power system, then the waves of unwanted harmonics can be suppressed as small as possible. In addition, harmonic filter at the fundamental frequency can compensate for reactive power and is used to improve the power factor of the system. From the measurement results in the Diploma Program Campus FT Undip found that the influence of harmonic waves big enough. THDv reached 32.13% while the THDi amounted to 7.85%. It affects so cos phi cos phi measured just 0.72. After the installation of a passive filter, the value THDv and THDi be good lebik ie 1.61% and 0.39% to reach 0.94 cos phi measured.

Abstract

Ruky Sandra Ary M, Saiful Manan, in this paper explain that parking lot which is widely used today do not present an empty parking location data, causing the vehicle entering the parking area must first find an empty parking space. This led to queues of vehicles becomes unavoidable. Even vehicles must berputarputar first to find an empty parking space. Therefore, it needs a parking system that can alert parking block capacity is still empty. Parking tariff determination system also plays an important role, most of the park determines the rate only on the type of vehicle rather than on how much time parking felt unjust for some people. This study designed a microcontroller-based parking system that can determine the number of cars remaining at the same time counting parking rates is a unified tool that can be divided into two, namely, hardware and software as a mechanical system that will work as a control system and the process of calculating tariffs.
