Background •

•

•

Cassava or Manihot esculenta Crantz is tropical plant that can produce flour. Cassava can grow well in tropical land and indicated from Brazil (Radley, 1976). The abundance of cassava farms in almost every area. Many industrial houses / small cassava producing a snack with flavor variants, cheap production prices and interested teenagers.

Produce waste of cassava peel

 Trends in product of  cassava: Cassava chip

LITERATURE Hydrogen Cyanide (HCN) in Cassava 

1. Cyanide is the an-organic compound with cyanic as the main structure 2.

Cyanide is form of gaseous, colourless, odourless and easy typical yawning. Cyanide assumed as pollutant because of its properties of toxic for living things.

3. The tuber of cassava have white colour or  yellowish, in sweet flavour can produce for about 20 mg HCN or hydrogen cyanide per kilogram of fresh tuber and 50 times more of  cyanide in bitter tuber.

PROCESS MAKING

Exfoliation •

Exfoliate the cassava skin from the tuber of cassava

 Washing •

 Wash the skin and clean it

Seaming •

•

Seam the skin use the  blender, fill it  with the water appropriately.  After that, divided the solution into 3 solutions.

Extortion •

•

•

Divide first solution into pure solution  with extortion. Divide second solution into same solution (cassava skin and water) Divide third solution with extortion and storage it for about 3 hours.

Addition •

•

This solution of the cassava will be treated to the plant into 3 treatments. First treatment is use the pure solution that does not contain of cassava skin, second treatment is use both solution and cassava skin, the third treatment is use the precipitation water after it storage for about 3 hours. We will identify which one is the best solution as bio-pesticide. The pH universal tester is used to know how acid the solution of  cyanide in cassava, because hydrogen cyanide is acidic. In further, spectrophotometer analysis used to identify cyanide in cassava skin (Johannes, 2005).
