Abstract

The use of ground tank constructed by Telkom University for Rainwater Harvesting (RWH), is limited to environmental maintenance due to concerns regarding the quality of water in the underground tank. Therefore, this research aims to develop a remote monitoring device that uses Internet of Things (IoT) technology to monitor the pH, water surface, submerged materials, and water clarity levels in ground tank. To achieve the requirements, pH, ultrasonic-based volume, Total Dissolved Solids (TDS), and Turbidity sensors were selected due to the IoT connectivity. The enabling device, namely the ESP 32 microcontroller and Blynk platform were installed on monitoring dashboard on a tablet computer with 4GB of RAM. The result showed that calibration of each sensor had good accuracy, except for the Turbidity sensor due unavailable materials. In conclusion, the RWH monitoring system is suitable for use.

Abstract

Teknologi pengukuran kualitas air di lingkungan sekolah merupakan inovasi penting yang memungkinkan pemantauan kondisi air secara real-time, terutama dalam mengidentifikasi potensi pencemaran di sekitar sekolah. Dengan menggunakan sensor-sensor canggih untuk mengukur parameter seperti suhu, pH, oksigen terlarut, dan kekeruhan, sistem ini memberikan data yang akurat dan berkelanjutan. Data ini tidak hanya relevan untuk mendukung pembelajaran di kelas tetapi juga dapat digunakan untuk memantau kondisi lingkungan sekitar sekolah, mendeteksi adanya polutan, dan mencegah dampak negatif pencemaran air terhadap kesehatan ekosistem lokal. Kegiatan pengabdian masyarakat ini bertujuan untuk memperkenalkan alat ukur kualitas air digital di SMA Al Kautsar Labschool pada mata pelajaran Biologi. Sistem ini memungkinkan siswa untuk mempelajari dan menganalisis kualitas air secara langsung, serta memahami dampak pencemaran air terhadap ekosistem dan kesehatan manusia. Dengan demikian, program ini tidak hanya meningkatkan pemahaman siswa tentang ekosistem air tetapi juga memperkuat kesadaran mereka akan pentingnya menjaga kebersihan lingkungan sekitar sekolah. Melalui program ini, siswa mampu mengembangkan keterampilan dalam penggunaan alat ukur untuk penelitian ilmiah, serta meningkatkan kesadaran mereka tentang isu-isu lingkungan. Selain itu, kegiatan ini bertujuan untuk memperkaya metode pengajaran Biologi dengan memberikan pengalaman belajar yang lebih praktis dan interaktif, sehingga dapat berkontribusi pada peningkatan kualitas pendidikan sains di sekolah. Implementasi sistem ini juga diharapkan dapat menjadi langkah awal dalam Upaya pencegahan dan pengelolaan pencemaran lingkungan di sekitar sekolah.

Abstract

This paper discusses the water management conducted by Telkom University, including the fundamental considerations to be taken into account, the implementing organization, the design methods for rainwater systems, and practical experiences in constructing Rainwater Harvesting systems. The management is aware of the conditions and situations related to clean water users, estimates of clean water requirements, potential water sources, and the campus environmental situation. Based on various studies and supported by rainfall data from the Meteorology, Climatology, and Geophysics Agency, a simple calculation was used to derive the design of the Rainwater Harvesting system, which was subsequently implemented. There are several lessons learned from this implementation, including the need for improvements in the foundation structure of soak pits, recommending the construction of ground tanks during the dry season, and the flexibility of ground tank size depending on the availability of funds The abstract should state briefly the purpose of the research, the principal results and major conclusions.

Abstract

Changes in the quality of the lake environment due to human activities demand efficient and sustainable monitoring solutions. This research designed a navigation guidance system for the solar autonomous boat that operates independently using solar energy and designed as a modular navigation unit to support future swarm-based cooperation between multiple vessels. The system relies on GPS ATGM336H and GY-271 digital compass sensor as positioning and direction determinants, controlled by a TTGO ESP32 LoRa microcontroller. Navigation data is processed in real-time and sent over the LoRa network to a central or intership gateway. This research focuses on the development and validation of the autonomous navigation core, providing the necessary guidance capabilities for integration into a swarm unmanned surface vehicle (USV) framework. The test results showed that the boat could follow the destination's direction with an accuracy of 92%, where most of the trajectory was within the pre-programmed directional tolerance. The average direction error was recorded at 5.4 degrees, within acceptable tolerance limits. The system can adaptively maintain a stable heading and respond to aquatic environmental conditions. By establishing this stable autonomous navigation baseline, the system provides a scalable platform for future swarm implementations aimed at improving large-scale environmental monitoring. This system is considered successful as an intelligent and sustainable autonomous navigation solution.
