Abstract

           Tsamaroh Nidaa Putri, Priyo Sasmoko explains that accumulator is a combination of several pieces of cells used for altering the chemical energy into electricity energy used in motor vehicles. Accumulators are used continuously will shrink and drop so it needs to be recharged. To know the state of the battery voltage drop experienced the need for a measurement to determine the ability of the accumulator. Design manufacture accumulator discharge monitoring tool consists of a voltage divider circuit to know the big accumulator voltage in percentage form. Used also an ACS712 current sensor to detect the discharge current and LM35 temperature sensor to determine the temperature of the accumulator. The control system used is the Arduino UNO microcontroller and an LCD for displaying the measurement data. Normal voltage ranges accumulator 12,5V - 13,8V. Accumulator with a capacity of 5Ah takes 8 hours to process discharge when using 20 watt lamp load. If the voltage of the first accumulator on the LCD shows the percentage of 0 % then automatically the system will work to discharge  for a second accumulator. The duration of use depends on the large accumulator load used. Keyword:Accumulator, ACS712,  capacity accumulator, Arduino UNOReferencesAgustin, Leonandi. 2015.

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.

Abstract

Nisrina Zahra Elfani, Priyo Sasmoko explain that portable electronic devices have a problem, namely the resistance of electrical energy intake, because these electronic devices get energy from batteries that have limited capacity to store electrical energy. Electronic objects that have now mushroomed and become primary needs such as cellphones and laptops desperately need a tool to recharge batteries. Solar energy can be used to recharge the gatget batteries by converting them to electric power. This will be very useful for those who are field workers, travelers, and nature lovers who need battery charging devices without having to use an adapter that uses an AC source from PLN grids in homes, while in certain circumstances gadget users may not be at home or in a place that provides ac resources. One solution to this problem is the use of a power bank portbale solar charger. Portable power bank solar charger is a charger that is equipped with backup batteries and solar cells as a source of electrical energy. Realized a portable charger that uses the working principles of DC-DC converter circuits such as: buck-boost converter, buck converetr and boost converter as a voltage regulator that is used to charge electronic devices. The ADC channel on the microcontroller is used as feedback for the controller that is also present in the microcontroller used so that the converter output can be maintained at a certain value through setting the duty cyle PWM that drives the converter. This portable power bank solar charger uses a buck-boost converter system and can produce the desired voltage. Buck converters can reduce the output voltage from 5 Volt dc for the use of chargering handphone and boost converter can increase the output voltage around 19 volts dc for the use of notebook charging Keywords: powerbank, portable charger, buck-boost converter, solar cellReferencesGunawan. 2009.
