Analisa Tingkat Kematangan Buah Sawit Dengan Injeksi Tegangan Searah
Palm fruit is Indonesia's main communiqué as the largest foreign exchange
contributor processed into crude palm oil (CPO). However, the quality of CPO
that will be produced is influenced by the right level of maturity of palm fruit so
as not to cause losses from the processor. Losses from the palm fruit processing
can be overcome using a method that can determine the maturity level of the palm
fruit, one of which is by injecting the voltage in the direction of the palm fruit.
The purpose of direct voltage objection to the function of time in the palm fruit is
to obtain a voltage response relationship to the content of yield, moisture content
and free fatty acid (FFA) in the palm fruit. In this study, palm fruit was classified
into 4 levels of maturity, namely unripe, almost ripe, ripe and overripe given
direct voltage injection of 9 Volts for 1 minute with 3 repetitions using four
electrodes arranged parallel to obtain an electrical voltage response with an
electrode diameter of 1.4 mm. The distance between electrodes was chosen to be
4-6 mm from stainless steel materials, and the depth of the electrode to the palm
fruit is 3-5 mm. Palm fruit was injected with electrical voltage and obtained the
value of voltage response, electric current, resistivity and power of each level of
maturity. The electrical information obtained will explain the yield content, water
content and ALB in palm fruit in accordance with the classification of ripeness.
The results of the study obtained, that the palm fruit is said to ripen when it has a
voltage response value of 0.586 - 0.765 V, electric current 385 - 404.9 μA,
resistivity 40,197-54,523 Ωm, and power 0.238-0,299 mW. The results showed
that the maturity level of palm fruit based on its chemical content affects the
properties of electricity
