Abstract

Eki Yulian, Arkhan Subari in this paper explain that Power consumption in boarding houses still can not be monitored , so that power usage bill payments based solely on electrical equipment used in the room . This would be detrimental to the owner of the boarding when the power consumption is too large . But tenants boarding can also be harmed if rarely use electricity must still pay the electric bill to the owner of the boarding.Thus making the tool use of electricity for the purposes of calculating a dorm room at the end of the project , expected to assist in completing the problem. In this tool using optocoupler sensor mounted on a disc kwh meter analog and microcontroller will process the data readings from sensors optocoupler . The output of this tool will appear on an LCD (liquid circuit display) . Where is the data to be displayed is the amount of power usage and costs to be paid . In addition , the tool uses the SMS facility for monitoring power use. Thus the cost paid by the tenant to the boarding room owner would be more in line with the use of electricity in use by tenants boarding. Keywords :optocoupler sensor, microcontroller , SMSDAFTAR PUSTAKAAndrianto, Heri. 2008.

Abstract

Ari Wijayanto, Priyo Sasmoko, in this paper explain that for operation RFID Parking Area User Operating Method Electronic Parking Pricing ( EPP ) Based Arduino Uno we created to see the problems that occur at this time , where the application of the parking area where the management is still done manually, especially in terms of payments .. We design a tool capable overcome these weaknesses , ranging from providing information about the availability of parking space to the user before entering the parking area to the effectiveness of the method of payment , which uses an identity card balance . With this tool is expected to reduce queuing/ speed up queues of vehicles wanting to enter / exit the parking lot. The system is also supported by the Arduino Uno as the brain to process data from RFID . RTC components to calculate the time and date , LCD display , and a servo motor as the driving door portal. Infrared to close the portal and counting vehicles entering and exiting. Keywords : RFID, Operating User Parking Area, EPP, Arduino UnoReferencesMalvino. 1995. Prinsip-prinsip Elektronkasi.

Abstract

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. Keywords: Speed Deceleration, PWM Method, Ultrasonic Sensor, Arduino Mega 2650.ReferencesAgus Setya Abadi, Delta. 2008.

Abstract

Gasa Raflianto, Priyo Sasmoko, in this paper explain that design of miniature electronic methods parking place with parking pricing (EPP) based arduino uno created by looking at the problems that occur at this time, Berparkir is something that is often encountered in everyday dikehidupan. sometimes it is crucial to find the solution in order to provide convenience and comfort for the driver of the vehicle as well as the efficient use of parking space limitations. A lot of wasted time and sometimes quite a hassle just to queue entrance and exit of the parking lot during rush hour. Based on these problems, the authors provide a solution by designing a tool that can enable people to berparkir without having taken the trouble to enter and exit the parking lot without having to waste time and tenaga.Sistem is also supported by the Arduino Uno as the brain to process data from RFID, infrared is used to instruct the servo and servo motor is used as a parking portal. Keywords:, Servo, RFID, Infrared Sensor.ReferencesAnonim.

Abstract

Umi Setiyani, Arkhan Subari, in this paper explain that the maternal mortality rate in Indonesia is still high, every 1 hour, 2 maternal death. Lack of information about the health of pregnant women, to be one cause. By utilizing the WAP ( Wireless Application Protocol ) and expert systems can be made to maternal health expert system -based mobile website. Maternal health expert system is able to diagnose 15 to 61 illnesses symptoms often suffered by pregnant women . Diagnosis of the disease is designed using forward chaining inference engine with the aid of decision tables and decision trees . In addition the system is also able to calculate the daily calories needed by pregnant women using cooper . So with this system can help pregnant mothers to know their health condition . Keywords : expert system , Wireless Application Protocol , the health of pregnant women.ReferencesNatalia, Deasy Astrid. 2006.

Abstract

Dewantara, Priyo Sasmoko, in this paper explain that a measuring instrument is a tool used by humans to help determine parameters such as height and weight. Most height and weight gauges used today still use simple and still conventional equipment. In addition, if manually, there are still frequent measurement errors that come from the measuring instrument itself or from the human. This happens because of inaccuracies in reading measuring instruments that lack precision or perhaps from the human factor itself. The purpose of this study was to create a digital height and weight automation system accompanied by displaying its ideal weight based on height. This system is built using Arduino as a system controller. The ultrasonic sensor is used as a measure of height. Load cell is used as a measure of weight. And a 20x4 LCD to display the output. From testing and analyzing the results of measurements of height according to the actual height, the results of measurements of weight have an error percentage of 0.53% - 2.77%. The system determines the ideal or not body weight based on BMI. Keywords: 20x4 LCD, Load Cell Sensor, Arduino.ReferencesFogaswara, Eka. 2013.
