L) TERHADAP PERTUMBUHAN Ralstonia solanacearum JF - Medical Technology and Public Health Journal JA - MTPHJ VL - 2 IS - 2 SE - Articles DO - 10.33086/mtphj.v2i2.563 UR - https://journal2.unusa.ac.id/index.php/MTPHJ/article/view/563 SP - 109-114 AB - <p>This study aims to determine the effectiveness of antibacterial pineapple peel extract (Ananas<br>comosus. L) on Ralstonia solanacearum growth. Pineapple peel extract (Ananas comosus.L) contains<br>antibacterial compounds of bromelin and tannin enzymes that are able to inhibit the growth of plantcausing</p><p>bacteria, Ralstonia solanacearum. Ralstonia solanacearum bacteria will be given 5<br>treatments with pineapple peel extract 10%, 30%, 60%, 100% and positive control Streptomicin<br>sulfate 0.01%, each repeated 5 times. The test was performed by adding 100μl of Ralstonia<br>solanacearum suspension which was diluted into 15ml Tetrazolium chloride agar medium which was<br>given 100 ml of pineapple peel extract. The results showed that the treatment of pineapple peel extract<br>had a significant effect on the growth of Ralstonia solanacearum. The average number of treated<br>bacteria 60% (4x107 CFU), 100% (8x106 CFU) and Streptomicin sulfate 0.01% (4x106 CFU) was<br>significant (P &lt;0.01) higher than the number of bacteria treated by concentration 10% (1.79x108)<br>and 30% (1.27x108). Consentration 100% pineapple peel extract (Ananas comosus.L) is the most<br>effective in inhibiting the growth of Ralstonia solanacearum. Thus it can be concluded that pineapple<br>peel extract (Ananas comosus.L) is effective as an antibacterial Ralstonia solanacearum.</p> ER -
