Rancang Bangun Sistem Pengering Putar untuk Rumput Laut Berbasis Mikrokontroler

Eucheuma cottonii is a type of seaweed that cultivated in the coastal area Nagari Sungai Pinang, Koto XI Tarusan District, Pesisir Selatan West Sumatra Province. Before being sold, farmers must dry their first, because what can be sold dried seaweed. Drying takes two to three days depending on weather conditions. In this research drying system has been designed with tool rotates chamber. rotary system, soil moisture sensor used which functions detect content seaweed, if still read > 30% then microcontroller turns relay forwards instructions heater and DC motor starts rotating player container. The DS18B20 temperature chamber, total 30%, state reached. Tests have carried out determine difference time required between process using built study utilizes direct sunlight. To achieve it an average ±50 minutes, while sunlight ±9 hours
