Cigarette smoke is one of the sources of air pollution, due to its very harmful content, especially for health. The MQ-2 sensor is a sensor with high sensitivity and fast response time to detect the presence of cigarette smoke. This study used an Arduino Nano microcontroller as a circuit controller using C language as a programming language. The outputs made are a 16 x 2 LCD display and an AC-p…
This study analyzes the GFR core with a CANDLE burn up strategy with a variety of fuels, Uranium Carbide (UC) and Uranium Nitride (UN). UC and UN are used as starter fuel and natural uranium is used as fresh fuel. The simulation uses the Monte Carlo method in the OpenMC program and uses the ENDF/B-VIII.0 library. The calculated physical parameters are conversion ratio, effective multiplication …
The mass of cold seawater from the seabed is lifted up to the surface is referred to as upwelling. Due to the influence of Ekman Transport and the Coriolis Force. Some of the parameters used to review the occurrence of upwelling in the Positive IOD event are Sea Surface Temperature, Sea Level, Wind and Chlorophyll-a. Descriptive method as the method used to analyze the results of the image of e…
Melamin berpotensi menghasilkan monomer beracun berupa formaldehid yang berbahaya bagi kesehatan manusia. Maka dari itu dirancanglah sebuah alat ukur untuk mendeteksi nilai konsentrasi dari melamin. Alat ukur yang dirancang dalam penelitian ini berbasis Mikrokontroler NodeMCU ESP8266. Prinsipnya alat ukur ini mengukur nilai tegangan pada kedua elektroda yang terjadi akibat adanya perpindahan io…
Research has been carried out on the development of vibration monitoring on induce draft fan utilizing the ADXL345 accelerometer sensor using fast fourier transform (FFT) method based on Labview. Measurements using a monitoring system are useful for reducing the risk of excessive vibration in the engine. This accelerometer sensor will be used to measure the occurrence in the induced draft fan u…
