Abstract

Water quality is a crucial factor in supporting life, especially in water storage systems used for domestic and industrial purposes. A common issue that arises is the degradation of water quality due to increased turbidity, which can pose health risks and reduce water utilization efficiency. This study aims to design and develop an intelligent Internet of Things (IoT)-based system capable of real-time water quality monitoring and automatic cleaning of water storage tanks when turbidity exceeds a predefined threshold. The system utilizes a turbidity sensor to detect water clarity levels, a SIM900A GPRS module for data communication, and an Android application for real-time data visualization to the user. Monitoring and cleaning processes are controlled by an Arduino microcontroller integrated with an SMS-based alert system and a mobile user interface. Test results show that the system accurately detects turbidity levels, transmits data in real-time to the Android app, and automatically activates the cleaning mechanism when necessary. Additionally, the system can send early warning notifications via text messages. Therefore, this system offers an effective and efficient solution for maintaining water quality in a sustainable manner and contributes to the application of IoT technologies in smart water resource management.

Abstract

Pendidikan sains dan teknologi pada jenjang sekolah dasar memegang peranan krusial sebagai fondasi dalam membangun kemampuan berpikir kritis dan literasi STEM (Science, Technology, Engineering, and Mathematics). Namun, pembelajaran konsep kelistrikan di sekolah dasar sering kali masih terbatas pada metode teoretis konvensional, sehingga siswa mengalami kesulitan dalam menghubungkan konsep abstrak dengan realitas fisik. Kegiatan pengabdian ini bertujuan untuk memberikan pelatihan dan pendampingan praktikum pengenalan rangkaian listrik seri dan paralel bagi siswa kelas 5 SDN Karangrejo 2, Desa Karangrejo, Kecamatan Kandat, Kabupaten Kediri. Metode pelaksanaan menggunakan pendekatan praktik langsung yang meliputi tahap koordinasi, penyuluhan materi dasar, serta praktikum perakitan langsung secara berkelompok menggunakan trainer kit sederhana berupa baterai, kabel penghantar, fitting lampu, dan sakelar. Hasil kegiatan menunjukkan adanya peningkatan pemahaman konseptual yang signifikan, di mana siswa mampu membedakan karakteristik fungsional antara rangkaian seri dan paralel secara empiris. Selain itu, kegiatan ini berhasil menumbuhkan antusiasme tinggi, keterampilan motorik halus, kerja sama tim, serta minat belajar sains pada peserta didik.
