The problem that occurs at this time is that the production process is often hampered and does not reach the set targets because the Rolling Stand 3 (mill section) machines are often damaged. Rolling Stand 3 machine (section mill) is used to form steel with a grinding process (rolling). The study was conducted using the Overall Equipment Effectiveness (OEE) method where Overall Equipment Effectiveness (OEE) is a systematic method for measuring the level of machine effectiveness. Overall Equipment Effectiveness (OEE) calculations can be gauged from actual data related to Availability, Performance Rate, and Quality Rate. Overall Equipment Effectiveness (OEE) is used as an indicator, to find out the causes of machine ineffectiveness done by calculating Six Big Losses to find out what factors influence the Six Big Losses. Based on the research results for the period January - December 2015 on Rolling Stand 3 (mill section) machines, the Availability value was 55.77%, Performance Rate 60.05%, Quality Rate 97.82% and Overall Equipment Effectiveness (OEE) was 32.86 %, meaning Overall Equipment Effectiveness (OEE) below the standard value for world-class, which is 85%. To maximize overall machine effectiveness, improvements are needed to the factors that influence the low amount of Overall Equipment Effectiveness (OEE). When viewed from the six elements Six Big Losses, the greatest value is found in the Equipment Failure factor.

Fikri Musthofa, Heru Winarno, in this paper explain that along with the high number of accidents on the highway at this time of course must be a special concern for motorists. There are many factors that underlie the occurrence of an accident in driving, the most important of which is the factor of driver error in driving, such as drowsiness or lack of rest, lack of concentration, and much more. Besides the security system in vehicles is also very influential in reducing the number of accidents in driving. With the development of today's technology, it is necessary to create a speed deceleration system on the motor based on the distance to the barrier objects in front of the vehicle using ultrasonic sensors. Ultrasonic sensor which is a type of proximity sensor is a sensor that can detect distances so that it can be used as a sensor in this system. This system can reduce motor speed automatically when the sensor detects a barrier object in front with a distance of less than 300 cm. This system will be active when the ultrasonic sensor detects a distance of less than 300 cm. At that distance the Arduino Mega 2560 will adjust the PWM value of the motor, the motor PWM value will decrease 12% every second so that within a period of 8 seconds the motor will have a speed of 0 rpm which means the motor will stop. This system is expected to reduce the number of road accidents due to motorists' faults.Â Keywords: Speed Deceleration, PWM Method, Ultrasonic Sensor, Arduino Mega 2650.ReferencesAgus Setya Abadi, Delta. 2008.

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..

PROTOTIPE SISTEM AUTOBRAKE PADA MOBIL MENGGUNAKAN SENSOR JARAK ULTRASONIK HC-SR04 BERBASIS ARDUINO MEGA 2560 Hidayanto, Ari; Winarno, Heru

Ari Hidayanto, Heru Winarno Â in this paper explain that The high number of traffic accidents is currently a factor in the driver's error in driving (human error). One of the accidents that often occur include car accidents. Of the several incidents that have occurred, the average accident occurred because of the driver's lack of concentration in driving his car. This resulted in the driver not being able to control the speed of the vehicle immediately when there was a sudden object in front, moreover this happened when the vehicle drove at high speed. To avoid this, when driving, it really needs a vehicle security system that also greatly affects the driver's safety. With the development of existing science and technology allows humans to make security systems in motorized vehicles. Accidents due to driver negligence can be overcome by making the braking system automatic then the vehicle speed will slow down and carry out mechanical braking (disc brake) automatically based on the minimum distance of the car with the barrier even though the driver does not pull the brake lever. Realizing this, an autobrake system (automatic braking) was designed based on the distance of the car with the barrier using the HC-SR04 ultrasonic distance sensor. When between a sensor and a barrier at a distance of <= 70 cm, the central lock actuator will go forward and press the disc brake lever. System notifications will be displayed via 20X4 LCD, LED and Buzzer. The system work will be controlled by Arduino Mega 2560.Â Keywords: Autobrake, Disc Brake, Ultrasonic sensor HC-SR04, Central Lock,Â LCD 20x4, Arduino Mega 2560ReferencesAgus Setya Abadi, Delta. 2008.

Â Hanif Zuraida, Heru Winarno, in this article describes the simulation of protection equipment coordination systems, especially in the recloser and sectionalizer areas. Coordination between protective equipment to improve the network reliability system so that in the event of a disturbance, the area affected by the disturbance does not spread widely. The simulation tool is made using OMRON LY2N 12V relay, ULN2803 relay driver circuit, ZMCT103C current sensor, voltage divider voltage sensor, pull down, 12V 6W lamp as a load and several resistors with different resistivity values as interference. Arduino Mega 2560 is used as the central controller for the entire circuit. After the experiment, the results obtained are when the normal network current at the recloser is 0.86 A and the current at the LBS SSO1 is 0.43. The recloser and LBS SSO1 coordination lies in zone 2 and 3 disturbances. When simulated zone 2 interference, the recloser current rises to 1.28 A, causing reclose / trip to lock out recloser. When the recloser feels a fault current in zone 3 of 1.06 A and LBS SSO1 senses a current of 0.64 A. The recloser as protective equipment will open first within 1000 ms after sensing the disturbance. When the recloser opens, the voltage on the SSO will be 0 volts and the SSO will open within 1000 ms after the current and disturbance requirements are met. Then the recloser will close again after 2000 ms from the open condition.
