PENGARUH LOGAM BERAT (Kadmium, Kromium, dan Timbal) TERHADAP PENURUNAN BERAT BASAH KANGKUNG AIR (Ipomoea aquatica Forsk) SEBAGAI BAHAN PENYULUHAN BAGI PETANI SAYUR

Abstract

Heavy metals Cd, Cr and Pb influence on humans in the long term and can accumulate in the body, especially the liver and kidneys. Water spinach (Ipomea aquatica) is a vegetable that is able to accumulate heavy metals contained in the water. Water spinach plant parts that contain many nutrients lies in the young stem and bud.The purpose of this research are: (1) determine the effect of Cd uptake of heavy metals (cadmium), Cr (Chromium), Pb (Lead) to the wet weight of water spinach (Ipomoea aquatica Forsk) based differences in harvest time, (2) determine the effect of heavy metals Cd (cadmium), Cr (Chromium), Pb (Lead) against wet weight in water spinach (Ipomoea aquatica Forsk) based differences in pruning, (3) prepare materials / extension materials eligible for the vegetable farmers of the results of research conducted. The study design was used completely randomized design (CRD). The sample was spinach plants in the bucket experiment Hoagland media containing heavy metal contaminated with Cd, Cr, and Pb. The treatment in this study is a variation of the harvest which is 5 days of the harvest, the harvest of 10 days, and 15 days of harvest and pruning. Data were analyzed by Anova One Way.
