Abstract

Abstract In 2015, forests in the Riau region experienced severe fires that also resulted in haze. The impact of the disaster, especially the Caltex Riau Polytechnic, was disrupted teaching and learning activities. The application of technology in the form of sensors as a system monitoring air quality can be used to assist in making emergency decisions for haze disasters, especially the Caltex Riau Polytechnic environment. The implementation of the GP2Y1010AU0F sensor as a detector for PM10 air levels, the DHT11 sensor as a temperature and humidity detector, the MQ-7 sensor as a detector for carbon monoxide levels in the air and the use of the ESP8266module WiFi as a medium for sending sensor data to the web as a monitoring system for sensors to users. PM10 sensor testing has an average error rate of 8.2% with a comparison tool, a temperature sensor of 8.42% and a humidity sensor of 2.89%. Monitoring is carried out via the internet via the web so that remote monitoring can be carried out as long as it is connected to the internet network. With this system, air quality information can be found through the website in real time. Keywords: haze, monitoring, decision making, realtime

Abstract

Electronic devices often cause an increase in Electromagnetic Interference (EMI) which has two types, namely Conducted Emission and Radiated Emission. One solution to reduce EMI mitigation is to use an EMI filter. Operational Amplifiers (Op Amps) are a form of Linear IC which has a function to amplify electrical signals. This final project will discuss the use of op-amps to minimize near-field EMI. In this case, an op-amp circuit is added to reduce the EMI of the clock source. One of the most important characteristics of the op amp is its extremely low output impedance. This study will design an active EMI filter to reduce conducted emission noise using an active EMI filter (AEF). The designed AEF filter provides excellent conducted emission noise attenuation with pre-filtered noise conducted at 118 dB which is reduced to 108.95 dB and provides excellent conducted emission noise attenuation (up to 9.05 dB).

Abstract

Riau Province is an area that has the largest peatland area on the island of Sumatra, namely ± 4.04 million hectares or 56.1% of the total area of ​​peatland in Sumatra (Wahyunto et.al., 2003). Illegal forest burning which often occurs in the province of Riau has resulted in worsening air quality and a haze that hits Riau Province almost every year. The creation of an air quality monitoring system specifically placed in the Caltex Riau Polytechnic environment can assist in making smoke emergency decisions. This system is designed using the NodeMCU ESP8266 as the Master Control Unit (MCU) and uses several sensors, including the GP2Y1010AU0F as a detector for airborne PM10 levels, the DHT11 sensor as a temperature and humidity detector, the MQ-7 sensor as a detector for carbon monoxide levels in the air. Sensor data is sent to the database and displayed on a local website page (localhost) in realtime. PM10 sensor testing has an average error rate with a comparison tool of 9.56%, a temperature sensor of 8.42% and a humidity sensor of 2.89%. With this system, the entire campus academic community will be able to find out information on air quality in real time and help the campus in making smoke haze emergency decisions in the Riau Caltex Polytechnic environment.

Abstract

With the increasing complexity of digital devices and the development of wireless devices, there are many design and fabrication problems that are encountered. Especially the circuit module which sometimes causes Electromagnetic Interference in the equipment itself or excessive electromagnetic radiation resulting in Electromagnetic Interference (EMI) problems. Magnetic Near Field Probes are very effective in detecting EMI, which is Radiated Emission in the Near Field. In this study, the measured radiated signal was in the frequency range 0 - 150 KHz. The aim of this research is to be able to design and implement magnetic near field probe for low frequency applications in the 0 to 150 KHz range to detect Electromagnetic Radiated Emission. In this final project (TA), the design of a Magnetic Field Probe to detect low frequency Radiation Emission requires determining the dimensions of the probe as well as the constituent material of the coil core of the probe. The dimensions of the probe are 4mm in diameter, the number of turns 50 and the core material of the probe winding is iron. The resonant frequency of the probe is designed at 75 KHz. In the measurement process with a Magnetic Field Probe, a supporting circuit such as an Amplifier is also used to increase the sensitivity of the probe.
