This study aims to design and evaluate a wearable vest device capable of detecting and providing real-time alerts when elementary school students begin to slouch while sitting. The system employs an MPU6050 sensor attached to the back to measure body tilt angles, with data sent to an ESP32 microcontroller for processing. When the tilt angle exceeds a certain threshold, a buzzer is activated as a warning. Posture information is also transmitted to an ESP8266 using the ESP-NOW protocol and displayed on an LCD without requiring an internet connection. The device was tested directly in a classroom setting at MI Al-Khoeriyyah and demonstrated the ability to provide real-time responses, improve students’ awareness of proper sitting posture, and remain comfortable for use during extended learning activities.

Implementation of Aquarium Water Quality Monitoring System Using ESP32, pH Sensor, and Turbidity Sensor

This research aims to design a tool and implement an aquarium water quality monitoring system using an ESP32 microcontroller connected to a pH sensor and a turbidity sensor. This system is capable of monitoring pH values and water clarity levels through real-time input data from the turbidity sensor, and displays the data on an LCD screen. A buzzer will sound as an alarm if the turbidity level exceeds a predetermined limit. Test results show that the system functions stably and provides accurate results in identifying changes in water parameters. It is hoped that this system can be an efficient and cost-effective solution for fish hobbyists in maintaining aquarium water quality.

Implementation of a Trixbox VoIP Server to Support Communication at the Ma'hadul Qur'an Girls' Boarding School

Communication barriers are often the main cause of coordination issues in Islamic boarding schools, as experienced by the Ma’hadul Qur’an (MQ) Girls’ Dormitory at the Salafiyah Syafi’iyah Sukorejo Islamic Boarding School. Operational challenges, such as running out of phone credit or unanswered calls, frequently hinder administrators when making a series of calls (hunting)to confirm the study session schedule with the ustadz, ustadzah, and Muallim. In addition, the flow of information from the central dormitory, coordination with the girls’ tahfidz administrators, and cross-sectoral communication with the MQ boys’ administrators tends to be slow. As a solution, this study implemented Voice ovel Internet Protocol (VoIP) technology using a Trixbox server. Through this infrastructure, all members of the administration can communicate with one another via the local Wi-Fi network without incurring call charges. The hunting system was also optimized so that emergency calls coordination between dormitories can be connected immediately and effectively. The result of the implementation demonstrate that the use of Trixbox VoIP has reduced communication bureaucrary at MQ girls, accelerated the coordination of teaching activities, and significantly reduced the dormitory’s operational communication budget.
