Abstract

The ability of plants to absorb metallic pollutants varies. The research has been conducted to compare the effectiveness of Tanjung (Mimusops elengi) and Bungur (Lagerstroemia) plants in absorbing Pb metal in particulate matter. The effect of location and leaf height on the effectiveness of pollutant uptake was also observed. Sampling was carried out in July 2020-September 2020 by taking leaves that were not too dark or light in color. Leaves taken at heights 3, 6, and 9 m on Timoho side Street. The particulate and leaf samples were digested and then analyzed their Pb levels using an Atomic Absorption Spectrophotometer (AAS). The results showed that the Tanjung plants with denser leaves captured more particulate deposits than the Bungur plants. This plant is also more effective at absorbing and accumulating Pb metal, which is indicated by the ratio of Pb metal in the leaves to Pb in particulates which is higher than the Bungur plant. These results were consistent for each sampling period, at each location and each crown height.

Abstract

The aim of this research is to examine the influence of lifestyle on impulse buying behavior with Maqashid Syariah literacy as a moderating variable. The study technique is descriptive quantitative, and 100 UIN North Sumatra Faculty of Economics and Islamic Business students who utilize E-commerce were surveyed. Online Google Forms questions generate data for regression path analysis. Research shows numerous important conclusions: 1. Lifestyle has a significant effect on impulse buying with a coefficient of 0.217 based on path analysis. 2. Lifestyle also has a significant effect on Maqashid Syariah literacy with a coefficient of 0.604. 3. Maqashid Syariah literacy has a significant influence on impulse buying of 0.539. 4. Simultaneously, Maqashid Syariah lifestyle and literacy influence impulse buying based on regression tests and path analysis
