Abstract

This research is about the implementation of Smart School Bell based on the Internet of Things (IoT) with the aim of increasing the effectiveness of communication at IT Cendekia Elementary School. The background of this research arises from general problems related to the use of school bells that are still manual and less effective in conveying information to students and teachers. By utilizing the concept of IoT, this research develops a Smart School Bell that is automated and connected online. This research consists of three main stages, namely Pre-Input, Process, and Output. In the Pre-Input stage, the project concept was designed and a survey was conducted to SDIT Cendekia to understand partner needs. The Process stage includes the design and manufacture of the Smart School Bell tool, as well as setting the bell schedule automatically. At the Output stage, this project produces a school bell system that functions automatically with a human voice, increasing the efficiency of the learning process at school. Evaluation results obtained from filling out questionnaires by SDIT Cendekia educators show that the implementation of Smart School Bell has succeeded in increasing the effectiveness of communication at school with an average rating of 4,73 or very good.

Abstract

Chemistry laboratories at the secondary education level have a vital role in supporting learning and research. However, manual management often faces obstacles in efficiency, accuracy, and data accessibility. Following the Regulation of the Minister of National Education Number 24 of 2007, pH meters are mandatory equipment in high school chemistry laboratories. However, conventional tools are often inadequate for precise real-time measurements. This study developed a Smart pH system integrating the Internet of Things (IoT) and fiber-to-the-home (FTTH) technology for real-time pH measurement. This system was designed using a pH-4502C sensor, Arduino Uno, NodeMCU ESP8266, and Arduino Cloud and tested on five types of solutions relevant to the high school chemistry curriculum, including salt solution, vinegar, lime, liquid soap, and mineral water. The test results showed an average accuracy of 99% and a 1-1.6 seconds data transmission delay. The total loss of the FTTH network was 3.65 dB, within the ITU-T G.984 standard limit. This research supports the fulfillment of national standards and improves the efficiency and reliability of pH measurements, opening up opportunities for further innovation in chemistry education laboratory automation in Indonesia.
