| Popis: | Electromagnetic insulators have been investigated for their attenuation capacity. One of the raw materials available in Costa Rica is pineapple leaf waste (Ananas comosus). Therefore, the objective of this research was to evaluate, through a pilot study, the effectiveness of a biodegradable insulator in blocking electromagnetic waves generated by a frequency-modulated transmitter to promote proper germination of a corn (Zea mays) crop. The methodology involved developing a mini-greenhouse with its irrigation system, a frequency-modulated transmitter, and a magnetic flux meter. The insulator was obtained from pineapple leaves, which were processed into a paste and then dried in sunlight. It was then applied to the corn seeds, and the growing conditions and non-ionizing radiation were measured for 8 days, thereby also establishing the insulator’s degradation rate. Analysis of the variables revealed that the maximum and minimum seedling heights, eight days after the start of the trial, were greater for the group with the insulator (17 centimeters and 8 centimeters, respectively) compared to the control group (12 centimeters and 1 centimeter, respectively), indicating that the product promoted appropriate growth. In addition, the degradation rate was 15.96 % eight days after application, and the predicted time for complete decomposition was 41 days, suggesting that the formulation is biodegradable. |
