Sistem ini dirancang untuk mengotomatisasi pengaturan suhu dan pH dengan aktuator modul Peltier untuk pendinginan serta pompa buffer asam dan basa untuk stabilisasi pH. Pengujian dilakukan dalam tiga skenario dengan setpoint suhu 24°C, 27°C, dan 30°C serta pH 6, 7,5, dan 8. Hasil menunjukkan bahwa sistem mampu menjaga suhu dalam kisaran stabil dengan selisih rata-rata ±0,5°C hingga ±2°C dibandingkan thermometer manual. Namun, pengendalian pH masih mengalami fluktuasi, dengan deviasi rata-rata ±0,3. Skenario dengan suhu 30°C dan pH 8 menunjukkan tingkat kestabilan terbaik dengan angka kematian lobster terendah (10%), sedangkan pada suhu 24°C dan pH 6, tingkat kematian tertinggi (37,5%) terjadi akibat fluktuasi pH. Pengujian Quality of Service (QoS) menunjukkan rata-rata delay pengiriman data sebesar 4,67 ms, yang masuk dalam kategori sangat baik. Dengan hasil ini, sistem yang dikembangkan berpotensi meningkatkan efisiensi budidaya lobster air tawar melalui pemantauan jarak jauh yang lebih akurat dan responsif, meskipun masih memerlukan optimasi lebih lanjut pada pengendalian pH untuk menjaga stabilitas lingkungan akuakultur.

Abstract

Founded in 1990, Robithotul Ashfiya Islamic Boarding School has had students spread across the archipelago. However, the communication media between alumni and students are still limited to social media such as FB and What’sapp group. This makes information often not well-conveyed and well-documented. Since the place is located quite far from the city center, this Islamic boarding school is not well-known by the public, so it requires qualified promotional media. With the establishment of cooperation between the Islamic boarding schools and Universitas Qomaruddin, a solution is found to the existing problems, namely the realization of a boarding school website. The system development methodology used is SDLC (System Development Life Cycle). Feasibility studies and investigations are carried out directly to the site. Requirement analysis includes functional and non-functional requirements of the system. System design uses UML (Unified Modeling Language) and level diagrams. Application is in the form of system development using the CMS (Content Management System) wordpress and system implementation. Regular review and maintenance are with a direct mentoring system in the form of system management training and monitoring system use. The result of the community service is a finished product of a boarding school website and website management training for the boarding school system administrators. With the existence of the website, now the Robithotul Ashfiya Islamic boarding school can make promotions to the community more easily and provide better information to its students and alumni.

Abstract

Liquefied Petroleum Gas (LPG) is widely utilized as a primary energy source in household and industrial applications. However, gas leakage remains a major safety concern that can lead to fire or explosion hazards. This study presents the design and implementation of an Internet of Things (IoT)-based LPG leakage detection system equipped with real-time alert notifications via the Telegram application to enhance household safety. The proposed system integrates a NodeMCU V3 ESP8266 microcontroller programmed using the Arduino IDE and an MQ-2 gas sensor capable of detecting gas concentrations between 300 and 10,000 ppm. Performance evaluation was conducted through experimental testing that measured key parameters such as gas concentration detection accuracy, system response time, and data transmission latency. When the detected gas concentration exceeds the threshold of 300 ppm, the system automatically transmits an alert message to the user’s smartphone through Telegram. The results show that the system effectively detects gas leakage events with an average response time of 23.018 seconds and an average data transmission delay of 265.76 milliseconds, remaining below the 300-millisecond standard. The novelty of this research lies in the integration of IoT-based gas monitoring with real-time Telegram bot notifications optimized for household environments, offering a more responsive and user-friendly solution compared to previous detection systems. These findings demonstrate that the developed system provides an effective and reliable approach for early detection and prevention of LPG gas leak hazards.
