ABSTRAK
Danau Toba merupakan salah satu destinasi wisata paling penting di Indonesia, khususnya di kawasan provinsi Sumatera Utara. Seiring berkembangnya pariwisata di Danau Toba, kemungkinan terjadinya pencemaran lingkungan terutama pencemaran polusi air juga bertambah. Situasi ini membuat perlu adanya sebuah sistem yang dapat memonitor kondisi kualitas air di Danau Toba. Dalam penelitian ini, penulis mengembangkan sebuah metode untuk mengumpulkan data dari polusi air yang terdapat di Danau Toba secara real-time. Metode yang dipakai dalam penelitian ini mempunyai beberapa parameter yang diukur yaitu tingkat oksigen terlarut air, tingkat pH air, tingkat suhu air, tingkat ORP air, tingkat suhu udara dan tingkat kelembaban udara. Sensor ini akan diletakkan di beberapa lokasi di atas permukaan air Danau Toba untuk meningkatkan keakuratan pengukuran. Dan hasil dari penelitian ini sudah menunjukkan bahwa beberapa tempat di Danau Toba dapat dimonitor secara efektif.
Kata kunci: sistem real-time, polusi air, Danau Toba, sensor air, wireless sensor network.

REAL TIME MONITORING SYSTEM FOR WATER POLLUTION IN LAKE TOBA
ABSTRACT
Lake Toba serves as an important tourism attraction in Indonesia, especially in the region of North Sumatera province. As tourism in Lake Toba develops, the possibility of environmental issues in Lake Toba, mainly water quality, also increases. This condition increases the necessity for a system that can monitor the environment condition, especially the water quality in Lake Toba. In this paper, we propose a design and development to gather and process data about water pollution in Lake Toba in a real-time process. Our proposed design consists of several sensors which record several parameters, such as Dissolved Oxygen Level, pH level, Water Temperature, Air Humidity and Air Temperature. These sensor buoys will be placed on several locations on Lake Toba’s surface to increase the effectiveness of measurement, thus improving the measurement result. Finally, the real-time measured values from the sensors will be gathered and processed in one main controller; the experiment result shows that certain area can be monitored effectively.
Keywords—real-time system; water pollution ; Lake Toba, water sensor device, wireless sensor network.
