The Effect of Garengpung (Dundubia Manifera) Insect Sound Intensity Level towards the Growth and Productivity of Rice (Oryza Sativa) Plant

Abstract:

This study aimed to determine the effect of the sound intensity level (SIL) of garengpung (Dundubia manifera) insect manipulated at a peak frequency of 4000 Hz on a horizontal plane towards the growth, stomata opening area, and productivity of rice (Oryza sativa) plant. This study employed the garengpung's sound, which was validated using the Octave 4.2.1 software. Lands used in the study were experimental and control lands; the area of each land was 30.0 m2 x 8.5 m2. The observed data included the rice plant growth, stomata opening area, and rice productivity. The stomata opening area was observed using a light microscope and the output was observed using NIS Elements Viewer software. In order to measure the area of the stomata, the Image Raster 3.0 was used. The productivity of the rice plant in the form of the rice mass was measured using Origin 8.0 and Microsoft Excel 2013. The SIL was measured using a sound level meter. The result of the study showed that the average growth of the experimental and the control plants at the 77th day after planting were as follow: plant height (87.98 ± 0.05) cm and (81.96 ± 0.05) cm, numbers of tiller in one cluster (17 ± 1) and (16 ± 1), and numbers of spikelet in one cluster (11 ± 1) and (10 ± 1), respectively. It was found that the productivity of the experimental plant was better than the control plant. From 1763 and 1819 clusters of the experimental and control plants, respectively, yielded 228.5 kg and 105.4 kg in total masses of rice. The SIL of the garengpung’s sound was in the interval of 62.1 dB to 79.4 dB.
