<p align="justify"><strong><em>Alcohol and pH levels in hand sanitizer are two things that need to be considered. The amount of alcohol content affects the level of effectiveness in killing germs, while the pH level is a factor that indicates whether the liquid is safe for human skin or not. HANDSIOT is a device to measure alcohol levels and pH in hand sanitizers. HANDSIOT is operated by testing the hand sanitizer liquid in the liquid container at the bottom. This device is made to be able to take measurements effectively and can monitor the measurement results in real-time using a smartphone. Gas chromatography and electrolysis methods were implemented using the MQ-3 gas sensor and the SEN0161 pH sensor. The gas chromatography method is used as a method of measuring alcohol content based on the evaporation of the alcohol. While the electrolysis method is used to measure the pH degree by measuring the amount of current flowing using two electrodes. In testing the accuracy of this tool by comparing the readings on the tool with an alcohol meter and also a pH sensor that is already available on the market</em></strong><strong></strong></p>

Ph Level

One parameter of air quality is the level of turbidity and acidity. For most people, air quality is considered insignificant because it is inappropriate for aesthetics. Good water to be issued according to regulations issued by the government through the Minister of Health of the Republic of Indonesia has a pH value of 6.5 - 8.5 and the maximum turbidity level is 5 NTU (Nephelometric Turbidity Unit). Therefore the author makes a measuring device for acidity in water to facilitate the use of water that will be used by the community. Processing the measurement results is carried out by a pH sensor which will be processed by the Arduino Uno Microcontroller and produced with output via LCD (Liquid Crystal Display). In this test, the author uses several air samples that have been determined by the government, namely pH 4, pH 7 and pH 10. And from several other samples using water that is reasonably suitable for consumption with a pH level of 6.5 and above and can be used as Neutral.

This paper introduces an analysis technology in detecting the alcohol content in human blood after drunken that bases on reflectionof Raman spectroscopy. This is a fast, non-contact, health and safety technology which take advantage of the human skin. The technology has a broad application in rapid detection of alcohol content in human blood.
