Abstract

The coastal waters of Parepare City are surrounded by numerous food stalls whose wastewater and food residues are often discharged directly into the marine environment, leading to seawater pollution. Continuous monitoring is therefore required to assess water quality and support effective environmental management. This study aims to develop an Internet of Things (IoT)-based web server system for monitoring the seawater pollution index in the coastal waters of Parepare City. The research adopts a quantitative Research and Development (R&D) approach by integrating pH, turbidity, and Total Dissolved Solids (TDS) sensors to collect real-time water quality data. Sensor readings are transmitted to an IoT-based web server and processed to calculate the Water Pollution Index (WPI). Experimental results demonstrate that the system operates effectively under field conditions. Morning measurements produced a pH value of 6.9, turbidity of 2443 NTU, and TDS of 1179.1 ppm, resulting in a pollution index of 1.91, classified as lightly polluted. Afternoon measurements indicated a pollution index of 2.04 with increased turbidity, which also falls within the lightly polluted category. The proposed system provides a reliable solution for real-time monitoring of seawater quality in the coastal waters of Parepare City.

Abstract

This research focuses on energy-saving solutions through IoT-based smart homes. Telegram-based multi-point control system is designed to optimize the use of electronic devices. The purpose of this research is to design and develop a Telegram-based on/off multi-point control system on automatic lights to optimize the use of electronic devices, improve energy efficiency, and adapt to technological developments and modern lifestyle needs. The method used in this study is qualitative based on RND, which aims to develop and test new or improved products with a focus on numerical measurements. The test results were analyzed to assess the performance of the system in responding to commands at various distances and conditions, both with and without obstacles.
