Evaluation of ipomea carnea growth response in plant media that was exposed by Sidoarjo Mud

Abstract

Krangkungan (Ipomea carnea ssp. Fistulosa) is a wild plant that has the ability to remediate wetlands polluted by toxic substances. Investigation of I. carnea's ability to survive and thrive on land exposed to Sidoarjo mud is needed to enrich information for future management. This study aims to determine the relationship of Sidoarjo mud concentration to 30% levels and incubation period of planting up to 70 days after planting on the growth rate and production of plant biomass. Sidoarjo mud-free krangkungan seedlings were transferred into polybags containing planting media with Sidoarjo mud composition and normal soil 0: 100%, 10: 90%, 20: 80%, and 30: 70% each as many as four plants. Observation of plant growth starts from 10 days after planting (HST) to 80 HST. The incubation period or observation time with the 10-day interval (10-70 HST) and sludge concentration are independent variables in the linear regression model related to growth and production of biomass as the dependent variable at the 5% real level. Linear regression analysis of data obtained using the SPSS statistical analysis package (version 18). Sidoarjo mud and incubation time affect the decrease in height growth rate, stem diameter, number of leaves, leaf area, and weight of I. carnea in 70 days after incubation of planting. I. carnea is able to grow well in soil mixed with mud up to a concentration of 30% even though the rate of growth and production of biomass decreases compared to lower mud concentration and without mud. Conservation of I. carnea on land that has been exposed to Siudoarjo mud has a prospect for the use of this weed for various purposes.
