Abstract

This article examines the dynamics of radicalism and terrorism in Indonesia and Malaysia and how government from both countries responded to the rise of radicalism and terrorism. It discusses the development of terrorism in Southeast Asia from the period of Darul Islam in 1950s to Jama’ah Islamiyah in 2000s. In addition, it argues that Indonesia and Malaysia have become barometer of terrorism networks in Southeast Asia. Radicalism and terrorism networks also have transformed the character of Islam in Southeast Asia, and this certainly challenges the future of mainstream Muslims in the region who are recognized as maintaining moderate and peaceful Islam. This is based on interviews to terrorist and former terrorist detainees and government officials in Indonesia and Malaysia. It also comes from analysis of books and documents from radical-jihadist organizations and government.  It recommends state and civil society policy to unite in preventing and countering radicalism and terrorism in Southeast Asia, especially in Indonesia and Malaysia.

Abstract

Abstract:. Copper deposits have been obtained by the electrolysis method using copper sulfate and sulfuric acid. The effect of copper concentration and current density on the surface morphology of copper deposits and current efficiency have been studied. The variation of copper concentration is 0.04 M and 0.8 M and the variation of current density is 2-8 A/dm2. The copper deposits will be photographed macro, weighed and characterized by Scanning Electron Microscope (SEM) to determine the surface morphology of deposits and Energy-Dispersive X-ray spectroscopy (EDX) to determine the chemical composition of deposits. The surface morphology of copper deposits in the form of compact and without nodules was reached at copper concentration is 0.8 M and the current density is 2 A/dm2 with the average of current efficiency is 96%.Keyword: Electrodeposition, copper, morphology, compact, current efficiency Abstrak: Endapan tembaga telah dihasilkan dengan metode elektrolisis menggunakan bahan tembaga sulfat dan asam sulfat. Penelitian ini mempelajari pengaruh konsentrasi tembaga dan rapat arus terhadap morfologi permukaan endapan tembaga dan efisiensi arus. Variasi konsentrasi tembaga adalah 0,04 M dan 0,8 M sedangkan variasi rapat arus adalah 2-8 A/dm2. Endapan tembaga yang dihasilkan akan difoto makro, ditimbang berat lapisannya dan diuji karakteristiknya dengan Scanning Electron Microscope (SEM) untuk mengetahui detail morfologi permukaan endapan dan Energy-Dispersive X-ray spectroscopy (EDX) untuk mengetahui komposisi kimia endapan. Morfologi permukaan endapan tembaga berbentuk compact dan tanpa nodul tercapai pada kondisi konsentrasi Cu 0,8 M dan rapat arus 2 A/dm2 dengan efisiensi arus mencapai rata-rata 96%.Kata Kunci: Elektrodeposisi, tembaga, morfologi, compact, efisiensi arus
