Performance of an AIOT-Particle Device for Air Quality and Environmental Data Prediction in Salatiga Area Using ARIMA Model
Get PDFThis study introduces the AIOT-Particle, a compact device designed for comprehensive air quality and environmental monitoring in Tegalrejo, Salatiga, Indonesia. Addressing the need for real-time, multi-parameter environmental data, the device simultaneously tracks PM1.0, PM2.5, temperature, humidity, pressure, and altitude, utilizing a built-in data fusion algorithm to ensure accurate and coherent data collection. Air pollution standards classify air quality as "good" (0–50), "moderate" (51–100), "unhealthy" (101-200), "very unhealthy" (201-300), and "hazardous" (>300). The research contribution is the development and validation of the AIOT-Particle using the ARIMA model for precise environmental monitoring. The methods involved deploying the device in Salatiga and applying the ARIMA model to analyze the collected data for accuracy. The results demonstrated promising accuracy: for PM1.0, the RMSE was 8.13 with an MAE of 6.04; for PM2.5, the RMSE was 6.60 with an MAE of 4.49. Environmental data analysis showed an RMSE of 0.74 for temperature (MAE 0.43), 2.11 for humidity (MAE 1.36), 0.25 for pressure (MAE 0.19), and 2.18 for altitude (MAE 1.70). These findings highlight the device's potential to enhance environmental surveillance and public health assessments, advance the understanding of air quality dynamics, and support targeted interventions to mitigate environmental risks. The novelty of this study lies in the integration of multiple environmental parameters into a single monitoring device, validated for accuracy using the ARIMA model

Performance Analysis of Hybrid Optical Access Networks That Combine Fiber to The Home (FTTH) and Radio Over Fiber (RoF) Using Wavelength Division Multiplexing (WDM) for Network Efficiency
Get PDFToday, people's need for communication has increased and telecommunication services have become basic needs in life. Therefore, broadband transmission system services are needed to support the quality of information flow between customers and the number of customers need access to available information. Fiber optic communication system is one that can be used to overcome these problems because it is very efficient and has high bandwidth. This system has several types of applications including for Fiber to the Home (FTTH) and Radio over Fiber (RoF). Usually, these two network systems are built separately, so the study of merging these two systems into a hybrid network is needed for future network efficiency. In previous research, several types of network combinations were carried out using the same wavelength, so they had to create separate components. In this research, a hybrid network design simulation was carried out using optisystem software that combines FTTH and RoF using Wavelength Division Multiplexing (WDM) so that only need to utilize existing components, then performance analysis was carried out in the form of power, Q factor, and Bit error rate (BER). WDM was chosen for several considerations, including increasing capacity, reducing costs, flexibility and scalability. The network is simulated using an OptiSystem, there is an FTTH system from transmitter to receiver consisting of OLT, ODF, ODC, ODP, to the ONT or customer device. Then there is the RoF system to support Wireless Gigabyte (WiGig) communications using QAM modulation. From the simulation carried out by varying the length of the fiber cable, the results of the FTTH network can be said to be suitable for meeting good performance parameters where the simulated performance value in the form of Q factor meets the performance feasibility standard of 6 and the BER is above 10-9, while the RoF at long certain cable system performance has not met feasibility. But overall, the hybrid system using multiplexing offered can work with the expected performance
