The City of Ilagan in the province of Isabela is one of the highly prone areas to flooding caused by the welling of the Cagayan River. Many communities are living in low-lying areas which most likely experiencing floods. An analysis of the location is conducted including the people living in the area. The analysis resulted in the development of an IoT-based technology for detection and early warning signals to people using sms notifications that can help lessen the difficulty of evacuation. The system uses Arduino UNO as a microcontroller where sensors are attached. These sensors are Light Detection and Ranging (LiDAR) for flood level measurement in feet (ft), Rain Gauge to measure the precipitation rate (mm/hr), and Flow Rate Meter to measure the fluctuation flow of the river in (L/hr). Data gathered from these sensors are processed and sent immediately to people living nearby to monitor the flood level in real-time. The predictive models are developed using the Pinacanauan River dataset taken from the river stations. The multilayer perceptron is used to develop the predictive model with 99% accuracy. The data from sensors are used also and processed using linear regression and calculated as 88% accurate and significant for prediction.

Agriculture is the backbone of the Philippine economy, contributing around 9% to its gross domestic product (GDP) and providing livelihood to millions of Filipinos. Local vegetables such as pechay, mustasa, sitaw, talong, and ampalaya are some of these essential agricultural crops, used in different famous dishes in the country. The emergence of technology helps individual and community improve their way of administering and managing crops, which is why it is very important to develop an innovative way to produce sustainable vegetable crops. The focus of this paper is on the creation of an application that can effectively categorize the ailments, pests, and nutrient deficiencies found in vegetable crops. This application uses different Convolutional Neural Networks architectures such as ResNet, YOLO, and Faster R-CNN to dissect information from digital photographs. By offering diverse insights into disease...

Due to the extensive requirement of distribution transformers, it becomes imperative to monitor their operational parameters to ensure their ongoing functionality. In this study, the researcher introduces a device and software solution specifically designed to monitor Electric Companies Distribution Transformer. By closely monitoring key factors such as voltage, current, apparent power, real power, reactive power, and power factor, potential issues with the distribution transformer can be identified and addressed promptly. The monitoring process utilizes real-time data, enabling the recording and analysis of daily, weekly, and monthly measurements via the Internet of Things (IoT) technology.

Specifically, XGBoost, Random Forest, and Decision Tree algorithms were employed and evaluated using accuracy, precision, recall, and F-1 score metrics. The study utilized six physico-chemical water parameters such as BOD, DO, pH, Phosphate, Ammonia, and Nitrate that came from Laguna Lake Development Authority (LLDA) from year 2017 to year 2022 as input for the classification model. Weighted Average Water Quality Index (WAWQI) was used as method for water quality index computation. The results showed that XGBoost with a learning rate of 0.10 had the highest accuracy at 96.72%, compared to Decision Tree with an accuracy of 93.45% and Random Forest with an accuracy of 93.35%. In addition, it also has the highest cross-validation score of 93.26% followed by Decision Tree with 91.24%. The findings suggest that XGBoost is a more efficient method for classifying water quality index in Laguna de Bay. The study's contribution to water quality management is noteworthy as it provides an efficient and effective way of classifying water quality index. These findings can aid in the decision-making processes aimed at ensuring the sustainability of Laguna de Bay and the health of its aquatic ecosystem.
