    People with visual disabilities, who have limited vision, will experience many obstacles in carrying out activities and social interaction. Equipment, in general, is not still user friendly for blind people. The purpose of this study was to create an automatic dispenser design that provides convenience and safety for visually impaired people when taking hot water to the dispenser. This study uses Arduino Mega microcontroller as the main control, proximity sensor to detect the presence of glass, and the HC-SR04 ultrasonic sensor as a determinant of high water levels and an SD Card Module to play sound. This research uses the Research and Development (RnD) method. The results of this study are an automatic dispenser that can fill glasses automatically with a glass height of 8 cm, 10 cm, and 12 cm. This dispenser can automatically tell blind people when the glass is full and turn off the tap when the water reaches 1-2 cm from the surface of the glass so that the water in the glass does not spill. Based on the test results, this automatic dispenser can detect glass of any color and make it from melamine, plastic ceramic, iron. However, this automatic dispenser cannot detect glass made of glass and transparent colored glass. When going to use hot water, blind people can choose a temperature with a setpoint of 50°C, 70°C, 80°C. The results of testing the tool using hot water show that the temperature of the water in the glass has a difference of 1°C - 3° C with a setpoint.

    Proceeding 2020 3rd International Conference on Vocational Education and Electrical Engineering Strengthening the Framework of Society 5 0 Through Innovations in Education Electrical Engineering and Informatics Engineering Icvee 2020, 2020
    Nowadays, one of the dynamic technological development is Voice Recognition. Voice Recognition can recognize someone's voice which can be used to facilitate work efficiently. Voice recognition helps the user match the voice which has been validated before and verify the compatibility of the sound with the user's voice so that it meets the biometric identification requirements. The purpose of this study is to determine the success rate of giving orders to the prototype of an automatic lamp using Voice Recognition Module V3. This research uses google voice with various languages by using the voice command “lights on” which means turning on the lights automatically, and “lights off” means turning off the lights automatically. Voice commands are taken in 9 random languages based on the availability of Google Voice. Also, this study aims to determine the effect of volume and distance on the performance of Voice Recognition Module V3. This study uses the distance between the microphone and the speaker in the range of about 5 cm, 10 cm, and 15 cm and also the volume of voice commands on google voice by 30%, 50%, and 100%. The results show that the volume of google voice on the cell phone is directly proportional to the percentage of the success rate of voice commands. While the results of testing the distance of the microphone with Google voice is inversely proportional. In conclusion, the Voice Recognition Module V3 can function well at a distance of 5 cm even with a google voice volume of 30%. Except in Chinese, because the vowel pronunciation of the word sounds faint. Vocal clarity of voice command pronunciation affects the success rate of voice commands.
