Monitoring outdoor air quality requires clear data visualization to enable rapid understanding of environmental conditions. This study develops an air quality visualization system using Streamlit based on CO₂, temperature, and humidity data obtained from the Air Quality Detection device. The data undergo preprocessing, quality classification, and analysis of trends and parameter correlations.…
Insider threat is one of the most challenging security threats to detect because the attacker possesses legitimate access rights to the system. This research aims to analyze an insider attack scenario that exploits legal access through the Secure Shell (SSH) service in the process of data acquisition and privilege escalation on a Linux system. The research method involves simulating insider act…
Modern agriculture increasingly relies on technology to improve efficiency and productivity, one of which is through the application of the Internet of Things (IoT). This study aims to develop an IoT-based automatic irrigation system for tomato plants with real-time temperature and humidity monitoring. The system is designed using the DS18B20 sensor to measure environmental temperature and humi…
Health is a fundamental aspect that every individual must pay attention to in order to maintain an optimal quality of life. Regular monitoring of bodily conditions serves as a preventive measure to detect potential health issues at an early stage, allowing for timely and appropriate intervention. With the advancement of digital technology, the integration of the Internet of Things (IoT) into he…
Device monitoring is an important part of IoT systems, especially for monitoring devices remotely. This study developed an IoT device monitoring system using the MQTT protocol based on a microcomputer. MQTT was chosen because it is lightweight and efficient with a publish-subscribe communication method. The Mosquitto broker is installed on a Raspberry Pi to manage communication between publishe…
Manual monitoring of household wastewater quality is inefficient and slow. This research aims to design a real-time monitoring system based on the NodeMCU ESP32 using Dissolved Oxygen (DO), Total Dissolved Solids (TDS), and Temperature sensors. The Fuzzy Logic method is used to determine the water quality classification (Very Good, Good, Moderate, Poor, Very Poor). The theoretical ideal model (…
Modern agriculture is undergoing a significant transformation with the adoption of Internet of Things (IoT)-based technologies under the smart farming concept. This study aims to design and implement a temperature and humidity monitoring system based on a microcontroller integrated with an Android application developed using MIT App Inventor. The system enables farmers to monitor field conditio…
Manual temperature control in LPG-fueled ovens often faces difficulties in maintaining the required temperature stability during the heating process, especially in small and mediumscale industries. Temperature instability can reduce product quality and decrease process efficiency. Based on these problems, this study aims to design and implement a temperature control and monitoring system for an…
This research develops a River Water Flow Velocity and Water Level Monitoring System Using RESTful Web Service. The system allows users to monitor river water conditions through a Laravel-based web without the need for direct monitoring in the field. The system implementation uses a BMP280 sensor to measure water level and a Speed Groove Coupler Photoelectric IR Count Counter sensor to detect t…
Water quality is crucial, because polluted water can endanger human life and other living things. One of the largest sources of pollution comes from industrial waste, but household waste is also no less influential. often, pollution occurs due to poor waste management. Several factors that need to be considered before disposing of waste into the environment are acidity levels (pH), BioChemical …
This research discusses the design and implementation of an Internet of Things (IoT)-based PVC water filter filtration monitoring system to monitor water quality parameters in real time, namely pressure, flow rate, and turbidity, and to record historical measurement results. The system uses an Arduino Uno as a data acquisition center and an ESP32 for wireless communication via the Blynk and Goo…
Forest fires are an issue that endangers ecosystems, public health, and the economy, especially in Indonesia, which has vast tropical forests. Most forest fire incidents are triggered by human activities, such as land clearing through burning, which is getting worse due to weak law enforcement and lack of environmental awareness. The smoke generated from these fires has a huge impact on social …
Household wastewater contains various dissolved substances (Total Dissolved Solids/TDS) that can reduce environmental quality if not properly controlled. This study aims to design and implement an Internet of Things (IoT)-based monitoring and control system for TDS levels using an ESP32 microcontroller, two automatic pumps, and activated carbon and air conditioner water as filtration media. The…
