Abstract

Seashell waste found in Tanjung Baru Beach, Karawang, which has not fully utilized. This waste can be widely used as an environmentally friendly material in various fields. Seashell waste is the source of CaCO3, and throughout the calcination process at the correct temperature, it can be converted to CaO. The purpose of the calcination process is to obtain a solid CaO by releasing CO2 gas. The calcination process can carry out at temperatures of 800 ℃, 900 ℃, and 1000 ℃ with a calcination time of 2 hours, 3 hours, and 4 hours. The seashell waste is characterized and analyzed using the Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy, and Energy Dispersive X-Ray (SEM-EDX). Before and after the calcination process, the FTIR spectrum of seashells is around 710 cm-1- 1476 cm-1, a characteristic peak of the C-O group from CaCO3.  The spectrum of 3429 cm-1- 3468 cm-1 is a characteristic peak of the O-H group from Ca(OH)2. The spectrum 2513.25 cm-1 is a characteristic peak of the C-H group containing CaO appearing after calcination. The seashell powder is analyzed by using SEM-EDX with the result where the most dominant elements are C (18.43%), O (52.07%), and Ca (27.86%) from the calcined shells. The elements C, Na, Al, Si, Fe, and Cu, are zero due to the heating process (calcination). The calcined seashell has also shown a rough surface and irregularly shaped particles.

Abstract

Activated carbon is a porous solid containing 85-95% carbon, produced from carbonaceous materials by heating at high temperatures. Activated carbon has a very large surface area so it is suitable for applications requiring large contact areas such as in the adsorption field. Activated carbon can be made from fish bones because fish bones are removed as a waste containing carbon elements that can be used as raw material for making activated carbon. In the manufacture of activated carbon, not only raw materials that need to be considered, but also the process of activation. Activation of the charcoal can be carried out using CaCl2. For charcoal base material from fish bones containing lots of Ca and Mg elements, in addition to using the activator, also the activation process needs to be immersed in H2SO4. Characterization of activated carbons of synthesis include water content test, ash content test, and functional group analysis using FTIR spectroscopy. Based on the results FTIR shows specific peaks for as charcoal activated charcoal based on the literature. Based on the determination of the test water content and ash content obtained by activated charcoal from fish bones has a water content of 4,1% and ash content of 28,1%.
