| Abstract | This research aims to study the effects of fermented natural rubber serum with bacteria and its application in promoting plant growth. The natural rubber serum was fermented with Bacillus aryabhattai (CKNJh11) at 37°C and then tested for its effectiveness in enhancing the growth of water spinach (Ipomoea aquatica Forssk.). The experiment included treatments with unfermented natural rubber serum, natural rubber serum fermented with bacteria for 7, 14, 21, and 30 days, a positive control using chemical fertilizer (25-7-7), and a negative control without fertilizer application. The results showed that B. aryabhattai (CKNJh11) was able to grow and increase in number in the natural rubber serum. On days 7 and 14, the bacterial population was recorded at 2.5 × 106 and 5.0 × 107 CFU/ml, respectively. However, the bacterial population declined on days 21 and 30, reaching 1.0 × 106 and 4.0 × 103 CFU/ml, respectively. When the fermented natural rubber serum was applied to water spinach, the treatment with natural rubber serum fermented for 14 days resulted in the highest growth rate. The average stem height, stem circumference, and root length were 36.38, 2.80, and 32.02 cm, respectively, with an average leaf number of 11.11 leaves. In contrast, the treatment with unfermented natural rubber serum showed the lowest growth rate, with an average stem height and root length of 21.98 and 18.46 cm, respectively, and an average leaf number of 6.44 leaves. These findings suggest that natural rubber serum fermented with B. aryabhattai (CKNJh11) for 14 days can effectively promote the growth of water spinach and serve as a potential biofertilizer for agricultural applications in the future. |
