Pengaruh Sonikasi Terhadap Sifat Fisik Formula Herbisida yang Ditambahkan Surfaktan Dietanolamida

Abstrak

Diethanolamide is a non-ionic surfactant from palm oil derivatives that can replace the
use of polyoxyetilenamine surfactant in a commercial herbicides. But there is a weakness in
the formula it has low visual appearance to the consumer industry. The aim of this research
was to study the improvement of herbicide characterization through sonication method. This
study was designed using a complete randomized design of 2 factors with factor 1 is the time
of sonication (0, 30, 60, 90 minutes) and factor 2 is amplitude (20%, 30%, 40%).The best
herbicide formula after sonication at 40% amplitude, 90 minute sonication time having a
surface tension of 23,42 dyne/cm, contact angle of 0^o and turbidity of 98 NTU.
