Abstract

The objectives of this activity are to disseminate the results of research to increase corn production in Limapuluh Kota District, to increase knowledge and skills of the community in making and using biofertilizers, and corn cultivation techniques. The method used is "Technology Transfer" with an integrated approach to motivate the community in a sustainable agriculture program with training, mentoring, and demonstration methods in Payakumbuh State Agriculture Polytechnic Experimental Field from August 2018–June 2019. The implementation consists of three stages: Training in house, manufacture of biofertilizers and application of biofertilizers on corn plants. Sources of bacterial inoculants are the Bacillus and Pseudomonas genera which are the result of isolation and identification of three locations of bamboo, corn, and rice plants in Limapuluh Kota District. Bacteria were inoculated when biofertilizers made from water hyacinth and fermented for 6 weeks and applied to a plot of land measuring 250 m2. The results showed the enthusiasm of the community in participating to make biofertilizers and demonstration plots. The output of this activity: Increased corn production 19% than without biofertilizer, increased of knowledge and skills of community in making and applying biofertilizers on plant increased 20–30%.

Abstract

Bacteria is a potential agent in biological organic fertilizer”s process. The rate of decomposition of organic matter in biological organic fertilizers process depends on the role of funtional bacteria, the type of organic matter and the microenvironment.  Bacteria that are inoculated into biological organic fertilizer’s matter must be synergistic among them, so that their role as as bioactivators more efficient.  A compatibility experiment among the bacteria isolates used as bioactivators have to be done in order to  obtain an effective and efficient biological organic fertilizer. The objevctive of the research is to obtain information on the compatible nature of the bacterial isolates. The research was conducted at the Plant Protection Laboratory of the Payakumbuh State Agricultural Polytechnic, West Sumatra from July to August 2022. The research method began with the rejuvenation bacterial isolates of Bacillus cereus, Bacillus subtilis, Bacillus thuringiensis on NA media, then continued with a compatibility experiment  using the dual culture method on NA and King’s B medium, so there were a total of 12 treatments (single and combination) with three replications. The results of the compatibility experiment on the three Bacillus bacteria did not form a halo inhibition zone and were compatible with the compatibility index value (IK) 0.67-1 on NA medium and 0.90-1.00 on King’s B medium, meaning that the growth between the three Bacillus bacteria did not inhibit each other, so that all Bacillus bacteria could be used as a bioactivator simultaneously in biological organic fertilizer’s process.
