Single box with a hand crank is a modification of the storey box [Fig 4.]. It has been introduced to targeted farmer in Kulonprogo. This box does not require a lot of material and space as a storey box. It has a capacity of 40 kg of cocoa beans. Cocoa bean's reversal technique is also different with storey box. Reversal of cocoa beans in this box is done by turning the crank as much as 3 times. Every side of the box is also given hole. The holes have a diameter of 1 cm and the spacing between holes of 5 cm. There are 40 holes to every side of the box, because the distance of the holes are shorter.
