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.

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

           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

Priyo Sasmoko, Subali, Teguh Yuwono, in this paper explain that harmonic (current or voltage) is one of the problems that has to be solved in electric power system, especially that caused by non-linear loads. Harmonic could cause bad impacts for the electric components that sensed it. It is almost certain that using of fluorescent lamp with electronic ballast or it is called energy saving lamp can cause harmonic in electric power system. Considering of the using of energy saving lamp is increased fairly fast as residence and office lighting, so it is important to analyze and solve the harmonic that caused by energy saving lamp. From the harmonic analysis, we can know the harmonic distortion caused by energy saving lamp. And there are some efforts to reduce such harmonic distortion by using a Low Pass Filter. Keyword: power quality, harmonic, low pass filter.

Meira Dwi Primanto, Priyo Sasmoko, in paper dummy CB as cubicle simulator for preventive and corrective maintenance to reduce off frequency 20 KV feeders (20 KV scada system at APD Central Java and Yogyakarta) explain that in 2013, the APD PT.PLN Central Java and Yogyakarta are conducting integration to SCADA at 20 KV feeders in distribution substation. For the next stage has been installed SCADA maintenance should be done periodically. Maintenance can be planned or due to interference with the SCADA system. Maintenance is usually done by the team must perform SCADA Distribution feeder outages and transfer of the load. In the installation of equipment, SCADA team should get a working permit to shut down the feeder, and to transfer the load to another feeder, so that the work has to get permission. SCADA systems are already installed requires maintenance to keep the system reliability. When maintenance SCADA, feeders should be extinguished, whereas for medium voltage customers such as factories, hospitals, and airports should always be channeled electrical energy. Feeder outages and load Delegation KWH lost causes. To the authors attempt to provide solutions that can overcome the missing KWH with a tool innovations made. The author makes a tool such as a dummy circuit breaker simulator 20 KV cubicles. This tool serves Especially when employees perform maintenance or investigation SCADA Disorders, which aims for 20 KV feeders should not be extinguished when performing preventive and corrective maintenance. So the number of frequency of feeder outages can be reduced. Keywords : Dummy Circuit Breaker, 20 KV PMT, SCADA maintenance.

Abstract

Almuhtarom, Priyo Sasmoko, in this paper explain that the existence of electrical energy for human needs can not be separated, the electrical energy used by all humans on this planet of small-scale (household) to large-scale industry. Demand the amount of electrical energy and the quality of the electricity transmission system has increased over time. Disruptions in electricity transmission system could be fatal for the electrical components or the operating loss in an industry. SCADA is proposed to accommodate this problem. SCADA is able to monitor and control the disturbances in electrical systems redundant. The purpose of this final project is to simulate a SCADA system to eliminate redundant electric power transmission network failures such as open-circuit, short circuit, and overload that can be controlled directly from the plant or via an interface on the computer. Ladder diagram programming languages ??used to design the PLC system. Hardware and software to support this thesis, such as plant redundant electrical systems, Omron PLC CP1E NA-20-DRA, Laptop, CX One 9.3 software for programming the PLC and the CX Supervisor 3.1 for building HMI. The test results indicate that the current sensor can be used to detect if an interruption occurs in the form of overload and short circuit simulate disturbances. Plant redundant electrical system can be monitored and controlled through input-output of the plant, computer interface, and the World Wide Web. There is a relay on a plant that can connect to the electricity grid cut power lines when an interruption occurs. If an interruption occurs in the form of an open circuit, short circuit or overload, alarm and disturbance indicators will be active. Keywords: SCADA, PLC, open circuit, short circuit, overload
