Recovery and Improvement of Cocoa Production With the Use of Nutrients from Chitosan-Tonnage Blending Ash

Abstract Cocoa is one of the plantation crops that provide a high economic contribution to Central Sulawesi Province in particular and Indonesia general be main income for local farmers. non-oil gas export commodity with demand, therefore government has determined cocoa as strategic needs increased productivity developed source State Sulawesi. The purpose this study was make chitosan-tonnage blending composition 80%-90% characterize it its optimal ratio restore soil nutrients, so plants can resistant pests Vascular Streak Dieback (VSD). Furthermore, fruit were powdered become raw material bispic products. Chitosan come from chitin, shrimp material, tonnage pods which have been hit by black borers. less productive farmer area 1 Ha, located Rantekala Village, Gumbasa District, SigiBiromaru Regency. results revealed diameter given nutrient elements chitosan-blending ashesat age ± 6 weeks 23 cm, compared only ZA / NPK fertilizer 14.5 cm at 7 weeks. length ash 28 while 21 production beans ashes 60% those fertilizer. conclusion nutrients could increase size around 37% diameters 27% lengths greater than
