Utilization of coconut shell ash (cocoa nucifera) in agricultural soil / Anis Iz'zati Ghazali

Coconut shell ash is one of agricultural waste. This waste was found a lot globally
and can cause risk to human health and also environment. An experiment was
conducted to study the usage of coconut shell ash in agricultural soil. Coconut
shell ash was formed by placing coconut shell in the muffle furnace. The
temperature of muffle furnace used for the formation of coconut shell ash was
500°C. After coconut shell ash was formed, Fourier Transform Infrared
Spectroscopy (FTIR) was used to determine characterization of calcium oxide in
the coconut shell ash. It was found that the wavelength for calcium oxide is
477.10 cm-I
. Determination of soil pH and soil properties of all the soil samples
were conducted after all soil samples included control soil was collected. There
are three portions of coconut shell ash that was applied to each soil sample which
were one gram, three grams and five grams respectively. The usage of coconut
shell was effective for rising pH of the soil. pH of the soil increase after the
application of coconut shell ash. The highest pH of the soil is after the application
of five grams of coconut shell ash. Hence, coconut shell ash can be used as a
liming agent.
