Pendugaan Kerusakan Mangga Arumanis Akibat Lalat Buah Menggunakan Ultrasonik: Zero Moment Power

Abstract

The objectives of this research were to determine zero moment power (Mo) number of arumanis mangoes, and to develop the prediction model of arumanis mangoes damage caused by fruit fly using Mo number. The method is based on measurement of zero moment power ultrasonic wave in arumanis mangoes. Results showed that mean of Mo number normal arumanis mangoes was 4.58 and Mo number arumanis mangoes damage caused by fruit fly was 6.40. Prediction model was Mo number more than 5.60 for normal mango and Mo number less than or same 5.6 for mangoes invested by fruit fly.
