Abstract

Sound is exotic thing that ready to be researched and explored. Although many researches were done on this theme, there are still many things that can be obtained when researching about sound. For example, levitate things with ultrasonic frequency. It is amazing that sound, which is like a vibe, can levitate things. From that idea, the writer fascinated to construct the water levitation circuit. In this project, with Arduino and a strobe light, the writer creates a design that makes it possible to see the water levitation phenomenon with using audible frequency.The device provides an optical illusion, so the blink of LED that hit droplets from tube, pumped by water pump, looks like levitate with human eyes.  This method can show the variations of water levitation phenomena with correct time setting of the blinking LED and frequency setting of the speaker. The synchronization frequency of LED and speaker will make the water stay. But, frequency of the LED higher than the speaker, then it will make droplets ascend and vice versa, if frequency of LED lower than the speaker, it will make droplets descend as normally it does.Keywords: strobe light, sound, droplets, levitation, optical illusion, LED.

Abstract

One of the functions of a digital clock is to wake us from sleep, in order to perform the activities as scheduled. Technological developments allow the incorporation of digital clock function with voice recognition, making it easier for us to do as to turn off the alarm without having to press a button, asking what time without having to view the display, and so forth. From these points of view, the idea to design and to implement a “Digital Clock with Speech Recognition” came up. This experiment concentrates in designing the hardware and the software that will work as an integration system of circuit that has the digital clock function. The circuit also has other function which is the speech recognition. Through this function, the user of the circuit will be able to record his or her voice in the form of short words. After the recording, the user can start to order the circuit to recognize his or hervoice. Finally, both digital clock and speech recognition functions are combined to work together, therefore when there is a voice recognized, then the speech recognition circuit will send a digital signal to the digital clock circuit to be processed as an input signal to operate certain digital clock function.Keywords: digital clock, speech recognition, microcontroller ATmega8535

Abstract

PT Dharma Electrindo Manufacturing is one of the compant in automotive manufacture. This company has two plants which are in Cikarang and Cirebon, with Cirebon focusing on the manufacturing side. PT Dharma Electrindo Manufacturing Cirebon branch has three floors for production. Thus it is necessary to have a freight elevator to ease production process on second and third floor with support from AGV (Automatic Guided Vehicle) with the market price of Rp 200.000.000 without humans directly controlling it. Several accidents could happen due to unsynchronized elevator door and AGV. In 2017, 15 accidents occurred on the elevator door on the second floor. Because of this, an early detection system has been implemented in the form of a crossbar on the door such that the AGV does not hit the acrelyte-made door which could cause the AGV to fall and caused the company loss about Rp 200.000.000 or the broken elevator door all through 2017 which caused Rp 202.250.000 loss. It is hoped that this crossbar implementation is developed using stabilizer.

Abstract

This project is the application of IoT for home appliances, in particular lighting. The prototype is making use NodeMcu as the main controller and free to use IoT platform BLYNK.  The combination of these two provides capabilities to control the lamp(s) remotely using smartphone connected to the Internet. The prototype uses Google Assistant to turn on and turn off the lamp remotely using voice command.
