The industrial revolution 4.0 is a hot topic discussed only among academics and industry. Of course, this condition is a positive thing that  shows  that  people  have  started  to   care  about  utilizing technology that is developing very rapidly today. South Aceh Polytechnic (POLTAS) as a vocational higher education institution, of course, must be consistent in making innovations in improving services to stakeholders. The quality and quality of service to stakeholders must of course be maintained so that input, criticism, and suggestions from them are one of the most important factors in creating a safe and comfortable academic atmosphere for higher education, especially POLTAS. The formulation of the problem in this study is how to build and simulate the results of an information system  that  can  adapt  dynamically in  carrying  out  the  political services of South Aceh provided to stakeholders. The purpose of this research is to build a Complaints Information System for the Polytechnic of South Aceh (SIAPA). This research is also part of the POLTAS Internal Quality Assurance System (SPMI) which is managed independently assigns to control and improve quality in the implementation of higher education in a planned manner (with designed) and sustainable (sustainable). This type of research is applied research with case studies at the South Aceh Polytechnic. The research procedure is in several stages, namely planning, analysis, design, development, testing, implementation, simulation of results, and evaluation.

Tape is a traditional food that is consumed by many people. Tape made using yeast by fermenting for 3-4 days covered with banana leaves to produce a sweet taste. Besides that the tape also contains alcohol from the fermentation of yeast and rice, if you consume too much tape, the body will feel hot because it does not know what percentage of the alcohol contained in the tape. To overcome such a thing, it is necessary to design a measuring device for alcohol content on food tape in order to know the percentage of alcohol on the tape. The Arduino Uno-based Alcohol Percentage Detection Device Design Series consists of three parts, namely the input part, the control part and the display part. Created to simplify the process of designing Alcohol Percentage Detection Devices on Food based on Arduino Uno. Where the MQ3 sensor is used as an input to get the alcohol percentage from the tape, Arduino Uno can be programmed in real time and the percentage data results will be displayed on LCD I2 Inc. Based on the test results it can be concluded that the MQ3 sensor which functions as an input and outputs sound in the form of a buzzer. The LCD functions as showing the percentage of alcohol on the tape. Tests that have been carried out get the results of the percentage of alcohol content on tape with five consecutive days of testing with an average of 22%, 39%, 46%, 57%, and 67%.
