Knowledge of Biological Science from Laboratories of Modification on PD.7 Fermentation Techniques for Removal of Mealy Bug, the Cause of Pineapple Wilt

Abstract

The current study aims to extend and promote the body of science knowledge that benefits an area-based development by using a synthesized model from research process. The proposed case study is the processing development of a new fermentation technique of the PD.7 that produces multi-enzyme, used for removal of Mealy bug which is the cause of pineapple wilt. The obtained model can be described in several steps. The first step is to engage the farmer in the scientific experiment with the missions to observe, investigate and take note of the results by themselves. The farmers reveal the experiment results that the use of soybean meal as a raw material for fermentation can induce the microbes to create at least 3 types of enzymes; glycoside hydrolase, protease and lipase. The produced enzyme succeeds in removing the mealy bug at a “very good” level. Farmers have accepted the new bio-extract fermented formula, with as much as 75% of the farmers deciding to use it after having learned its potential. The second step is to promote the outcome to other farmers. This involves dialoguing and publishing the results in a wider community. The last step deals with knowledge management and technology transfer project. The key techniques for success in raising farmers’ awareness include: 1) the transfer of newly-acquired knowledge from laboratory, 2) the availability of raw materials at a later stage for farmer’s demonstrations afterwards, and 3) the opportunity for knowledge sharing by visiting nearby farms. These techniques help empower the farmers to act and build upon their own activities.
