Abstract

Heavy metal pollution is found a lot in the environment, One of the alternative to reducing heavy metals from industrial waste by using adsorbent composite made from Spent Bleaching Earth (SBE) and Spent Mushroom Substrate (SMS). This study aims to determine adsorption capacity of the SBE-SMS composite against Cu2+ metal ion. This study used variation mass adsorbent 1, 3, 5, 7 dan 9 (gram), and contact time adsorption 60 minute. With adsorbent composition 25% SBE and 75% SMS, concentration artificial solvent Cu 20 mg/L, pH 5 and stirring speed 60 rpm obtained highest adsorption capacity was obtained at a mass of 1 grams with a capacity value of 2,9948 mg/g and the lowest adsorption capacity at a mass of 9 grams with a capacity value of 0,6568 mg/g.Key words: Adsorption, Composite, Spent Bleaching Earth, Spent Mushroom Substrate, Cu2+

Abstract

This articel's goal is to examine and debate the ethical principles that Indonesian Islamic banking practices have adopted as norms, particularly in resolving practical operational issues based on exploratory investigations. Four consumers and three managers of Islamic banks served as the research samples in this study, which was done at Islamic Banking in Cimahi. The analysis's findings suggest three things, all of which are supported by the notion of business ethics: First, Islamic bankers have been successful in forging cordial bonds with stakeholders and customers. Second, they consistently act responsibly while handling difficult situations and uphold high personal moral standards, even in the face of regulatory changes made by the parent bank. These are informal learning opportunities for writers and readers to fulfill their obligations so that they may apply moral principles to organizations. In order to increase the professionalism and operational quality of sharia banking in Indonesia, the author expects that this article will serve as a theoretical and practical resource and guide for regulators and sharia banking practitioners. The results still need to be verified and further generalized because this study's sample size and population coverage are restricted.
