Abstract


Taro are tuberous plants that are commonly found in Antasan Segera Village, Mandastana District. Taro leaves, which are often discarded in this study, are utilized as a pH neutralizing material in river water which has a pH level of 5. This study aims to determine the pH value of water before and after the application of charcoal from taro leaves, and to determine the best treatment from the results of charcoal application. This research is expected to be one of the solutions in neutralizing the pH of acidic river water and can reduce the volume of taro leaf waste in Antasan Village, Barito Kuala. The study used materials in the form of taro leaf waste made into charcoal and acidic river water samples taken from Antasan Segera Village. Water samples were given as many as 6 treatments of taro leaf charcoal consisting of P0 (control), P1 (1 gr/500 ml), P2 (2 gr/500 ml), P3 (3 gr/500 ml), P4 (4 gr/500 ml), and P5 (5 gr/500 ml) and each treatment had a replication of 4 times, so that 24 experimental units were obtained. The parameter measured was the pH of river water samples before and after the application of taro leaf charcoal. The results showed that the best treatment in reducing the pH value of water was P5 by 1.9, namely from water pH 5.1 to 7.
