Abstract

his study aims to design an alternative power generator using a thermoelectric generator (TEG) by utilizing a heating furnace, using two thermoelectric generators (TEG) connected in series. Thermoelectrics that take advantage of temperature differences can produce voltages that correspond to the seebeck effect. The alternative power generator that has been designed consist of a thermoelectric, boost converter, and a 5 Watt DC lamp load. The test was carried out using a Boost Converter and using a 5 Watt DC lamp load for 20 minutes. The results of the research using the Boost Converter produce a voltage of 42.8 V with a temperature difference of 90°C, while using a 5 Watt DC lamp load produces a voltage of 8.81 V with a temperature difference of 82°C and the resulting current is 0.6 A, the resulting power 4.84W.

Abstract

The adapter / power supply is a DC voltage source that is used to provide voltage or power to various electronic circuits that require DC voltage to operate. The main circuit of the power supply is  a rectifier, which is a circuit that converts an alternating signal (AC) into a direct signal (DC). The conversion process starts from rectification by the diode. In this paper, the Ripple Voltage Filter is carried out using a passive filter and the average voltage drop of the filter is 64%, the regulation (regulation) by the regulator circuit, the provision of this DC electrical energy source is to provide a unidirectional variable voltage ( DC) which aims to provide practical tools in Batanghari University electric laboratories while the benefits obtained from the research results are as a tool for practical activities in the electrical engineering laboratory of Batanghari University, Jambi.

Abstract

Blind people have difficulty in navigating due to the limited sensing they are capable of. In this research, we design a stick tool that can distinguish objects in the form of humans, animals and inanimate object based on camera. Processing is carried out with the Raspberry Pi with a webcam camera as input and indicators in the form of a buzzer and vibrator. The feature extraction process is carried out by deep learning using the tensorflow library and image processing using the Single Shot MultiBox Detector (SSD) method. Tests were carried out on human objects, animals (cats), and inanimate objects (chairs and tables) for indoor and outdoor conditions and obtained an accuracy of 92%, a sensitivity of 83%, and a specificity of 100%.

Abstract

In palm oil processing companies to become oil, the boiling process is carried out to make it easier for the loose fruit to come from the bunches, to stop the development of free fatty acids and will cause the tbs to soften so the oil extraction process becomes easier. The boiling process requires steam from steam. Steam is obtained by heating a vessel filled with water with fuel. Generally, boilers use liquid, gas and solid fuels. Steam functions as a boiling and electric generator, the company uses a boiler as a steam producer to support the production process. A boiler or steam boiler is a closed vessel used to produce steam through an energy conversion process. To find out the boiler efficiency, a calculation is carried out by taking the parameters needed for boiler operation, from the analysis the highest boiler efficiency results are 83.56% and the lowest is 75.25%, where the heating value with 13% fuel at 1000 Kw load is 83, 56%. And the calorific value with 10% fuel at a load of 750 Kw is smaller with a value of 75.25%.

Abstract

The use of DC source voltage obtained from solar cells and DC generators varies in value depending on the surrounding natural conditions, for that a controller is needed which functions to regulate the voltage in carrying out the charging process to the accumulator. This paper will discuss about the design of charge controller based on Arduino Uno R3 with ATmega328 microcontroller. This controller is used to regulate the charging process from a DC source with a maximum open circuit voltage of 24 Volts, which is then used to charge the 12 Volt accumulator. This charge controller works by sending a source voltage that is regulated by pulse width modulation. When the accumulator voltage is 13.8 Volt, the controller will carry out a charging process with a duty cycle of 95%, if the accumulator voltage is> 13.8 Volts and ˂14.4 Volts, charging will be carried out with a duty cycle of 10%, and if the accumulator voltage exceeds 14.4 Volt, the charging process will be stopped. Some protection equipment is also included in this charge controller such as overvoltage protection, overcurrent and also control of the connection breaker to the load when the accumulator voltage is weak, and a disconnect from source to accumulator when the accumulator condition is full. To show the work of the whole system, with the Arduino Uno R3 microcontroller the parameters of source voltage, accumulator voltage and percentage of accumulator status are displayed on the LCD screen then 2 LED lights and a buzzer as indicators during the charging process and when the accumulator condition is weak. From the results of the voltage reading on the voltage divider sensor, it has an error of less than 6.22% at the source terminal and 6.89% at the accumulator terminal..
