Krisis air bersih masih menjadi permasalahan global maupun nasional, khususnya di wilayah pesisir dan kepulauan terpencil yang memiliki keterbatasan infrastruktur penyediaan air bersih. Penelitian ini bertujuan untuk merancang dan mengembangkan Solar Dual System Distiller (SOLDUSTIL), yaitu sistem distilasi berbasis energi surya yang mengintegrasikan Parabolic Heat Concentrator (PHC) sebagai pemanas utama, Photovoltaic (PV) sebagai sumber energi listrik tambahan, serta sistem kontrol dan pemantauan berbasis Internet of Things (IoT). Metode penelitian meliputi perancangan perangkat keras yang terdiri dari reservoir, boiler, kondensor, PHC, dan sistem PV, serta integrasi sensor suhu, sensor pH, dan mikrokontroler ESP32 untuk pemantauan sistem secara real-time melalui aplikasi Blynk IoT. Pengujian sistem dilakukan menggunakan air laut dengan mengevaluasi kapasitas produksi air bersih, efisiensi proses pemanasan, konsumsi energi listrik, serta kualitas air hasil distilasi. Hasil penelitian menunjukkan bahwa sistem SOLDUSTIL mampu menghasilkan air tawar dengan kapasitas produksi sekitar ±3 liter per hari pada kondisi pengujian tertentu. Integrasi PHC dan PV mampu meningkatkan stabilitas proses pemanasan, sementara penerapan IoT memungkinkan pemantauan sistem secara jarak jauh dan real-time. Sistem yang dikembangkan berpotensi menjadi solusi alternatif penyediaan air bersih yang efisien dan ramah lingkungan bagi masyarakat di wilayah pesisir dan daerah terpencil.

The clean water crisis remains a global and national challenge, particularly in coastal and remote island areas with limited clean water infrastructure. This research aims to design and develop a Solar Dual System Distiller (SOLDUSTIL), a solar-based distillation system that integrates a Parabolic Heat Concentrator (PHC) as the primary heat source, Photovoltaic (PV) as an additional electrical heating source, and a monitoring and control system based on the Internet of Things (IoT). The research method includes hardware design consisting of a reservoir, boiler, condenser, PHC, and PV system, as well as the integration of temperature sensors, a pH sensor, and an ESP32 microcontroller for real-time monitoring through the Blynk IoT application. System testing was conducted using seawater by evaluating daily freshwater production capacity, heating efficiency, electrical energy consumption, and the quality of the distilled water. The results show that the SOLDUSTIL system is capable of producing freshwater with a production capacity of approximately ±3 liters per day under certain testing conditions. The integration of PHC and PV improves the stability of the heating process, while the implementation of IoT enables real-time remote monitoring of the system. The developed system has the potential to serve as an efficient and environmentally friendly alternative solution for providing clean water in coastal and remote areas.
