The Design of Automatic Audio Frequency Foliar Fertilization as Alternative Technology to Increase Productivity Result of Plant

Abstract

---------------------------------------------------------***--------------------------------------------------------------------- Abstract - Automatic Audio Frequency Foliar Fertilization is a technology that improves between the nutrients performed on plant leaves by giving the sensation of sound waves in plants. Automatic Audio Frequency Foliar Fertilization is technology device leaf fertilizer integrated with Sound waves which will run automatically, more practical and compatible. This technology device consists of two main devices of active speakers that will issue a sound with a certain frequency and sprayer fertilizer. The results of the tests that have been done to produce the sound frequency between 1200 Hz up to 1600 Hz with average noise of 5%, with the debit of nutrient spraying for the plant of 96 ml per 30 seconds. Giving exposure treatment Wave The sound of classical music with the provision of nutrients in mustard plants by Automatic Audio Frequency Foliar Fertilization gives a real effect on the growth of the average height of the plant is 2.14 cm per 2 days. application of sonic bloom technology in Indonesia is still relatively small. This is due to many things, low farmer knowledge of sonic bloom technology and the use of sonic bloom or AOGS technology that is not practical yet requires a lot of manpower and not yet compatible. Device technology sonic bloom or AOGS to generate sound waves still have to import and its use is still dominant manual. Based on this technology is designed device Amadio Frenzi (Automatic Audio Frequency Foliar Fertilization) is a leaf fertilizer technology combined with sound waves that will run automatically, more practical and compatible. This technology device consists of two main devices of active speakers that will issue a sound with a certain frequency and fertilizer spayer. The mechanism of this technology device is arranged by arduino uno so it will run automatically with the specified time. The two main devices will be arranged in tandem, the sound waves coming out of the active speakers will vibrate the leaf mouth membrane (stomata) to open and the target of nutrient spraying is directed to the leaf so that it can be absorbed maximally by the open stomata. The existence of automation in this tool provides advantages that can reduce human labor.
