Abstract

This study delves into the impact of MinMax normalization on Oriented FAST and Rotated BRIEF (ORB) data when utilized as input for an Artificial Neural Network (ANN). The primary objective is to compare the accuracy of an ANN model using two distinct types of input data: raw ORB data and MinMax-normalized ORB data. The results underscore the pivotal role played by MinMax normalization in significantly enhancing the performance of the ANN model. Through a series of comprehensive experiments, it becomes evident that MinMax-normalized ORB data consistently outperforms raw ORB data in terms of accuracy. Impressively, the highest accuracy attained through MinMax normalization reaches 76.6%, whereas the utilization of raw ORB data yields a maximum accuracy of merely 51.1%. This noteworthy improvement effectively validates the prowess of MinMax normalization in counteracting the adverse effects stemming from varied scales within raw data. As a result, the ANN benefits from improved pattern recognition capabilities and heightened predictive accuracy.

Abstract

The availability of clean water is a fundamental need for every individual, and PERUMDA Air Minum, has an important role in meeting this need in Indonesia. Water quality has a great influence on human health, so it cannot be ignored. This research developed an Internet of Things (IoT)-based raw water quality monitoring device for PERUMDA Air Minum Tirta Khatulistiwa Pontianak using a Raspberry Pi Pico W microcontroller. This device enables real-time monitoring, overcomes limitations in manual water quality monitoring, and provides remote monitoring access through the Blynk application. In addition, this research also implements the ARIMA method to predict the pH, temperature, and turbidity values of raw water in the sedimentation basin within the next seven days to support planning and treatment steps for raw water. The development of this tool aims to improve monitoring efficiency and proactive response to changes in water conditions, with the hope of being able to maintain clean water supply more effectively and overcome the constraints of manual monitoring. The results showed that the Mean Absolute Percentage Error (MAPE) of the performance of the constructed PDAM water quality monitoring device was 0,58%, while the MAPE of the predicted performance was 5,88%.

Abstract

The calculation of volume within a three-dimensional structure has the potential to determine its enclosed mass. This research aims to create a system that utilizes data from the HC-SR04 sensor to calculate volume, incorporating the Internet of Things (IoT) for remote monitoring. The study involves the use of HC-SR04 and DHT11 sensors to gather data on filled height and temperature. The measurement approach encompasses mathematical formulas for volume and surface area that correspond to the shape of the compartment. The ESP32 microcontroller serves as the central processing unit. Experimental trials are conducted, manipulating different height levels within the object. The results reveal differences between theoretical estimations and sensor-derived assessments, highlighted by varying outcomes in specific scenarios. The calculated volume of the filled compartment is displayed on OLED-1 and transmitted through the Blynk application. This study significantly contributes to the advancement of a sensor- and IoT-driven monitoring infrastructure, facilitating the observation of filled height and volume in physical objects. Despite certain variations observed in the trials, the outcomes consistently demonstrate minimal error rates.

Abstract

The liquid"™s level is given particular notice, whereby the liquid"™s level is maintained at a certain level to meet the volume requirement. The implementation liquid level control system involves the use of water pumps in water supply management at Selat Panjang, Pontianak. The water in reservoir must be maintained in a specific level range. If the water is too high or too low, it will significantly affect the reliability and safety of the pumps. Water level control in a reservoir is carried out by adding a controller to the system. The control equipment used is a PLC (Programmable Logic Controller). Then, mathematical calculations will be carried out using MATLAB. Calculations are carried out using 3 methods, namely the manual method, the Ziegler"“Nichols method, and auto-tuning method. When applying the three methods to the system, the observed manual method demonstrated stability with a P value of 1, I value of 20, and D value of 25, approaching the setpoint at 2.21 meters with an error of ±1.1 meters. The Ziegler"“Nichols had the longest rise time but achieved the water level close to the setpoint with an error of ±0.1 meter. The auto-tuning method exhibited a relatively fast rise time of approximately 1 minute and 20 seconds. However, the water level increasingly deviated from the desired setpoint. Implementation results concluded that the Ziegler"“Nichols is the most suitable for the system. This research is expected to enhance the efficiency, safety, and reliability of the pump usage at Perumdam Tirta Khatulistiwa.
