Abstract

This study explores the potential of Sea Pine Flowers from Pantai Pasir Jambak, Kota Padang, as a carbon source for advanced materials through carbonization. Carbon is generated by the incomplete carbonization process, which breaks down organic components. It can be obtained from organic waste materials that contain cellulose, hemicellulose, and lignin. Carbonization was performed at 350˚C for durations of 1 hour, 1.5 hours, 2 hours, and 2.5 hours. Analysis results revealed vapor content ranging from 2.18% to 2.69%, ash content from 4.44% to 8.06%, and bound carbon content from 89.25% to 92.88%. The highest bound carbon content was achieved at 350˚C for 1 hour (C-60). All results meet the SNI 06-3730-1995 standards. Low vapor and controlled ash content indicate high-quality carbon. This study confirms that Sea Pine Flowers have significant potential for advanced material applications as a high-quality carbon source.

Abstract

Used cooking oil, which is often discarded carelessly, can cause environmental pollution and adversely affect health if consumed again. This study explored the use of activated carbon produced from corn stalks (Zea mays) for the purification of used cooking oil. Activated carbon was produced through chemical activation using NaOH and applied to used cooking oil in various treatments, including combination with cornstarch. The quality of the purified oil was evaluated based on density, flow rate, saponification number, and acid number. The results of this study are expected to provide an environmentally friendly solution in the treatment of used cooking oil waste and utilize corn stalk waste effectively, thereby reducing negative impacts on the environment and improving public health.The result of this study is activated carbon from corn stalks which is able to reduce the density of 0.83 g/mL with cornstarch adsorbent, flow rate of 0.201 ml/s with carbon adsorbent, acid number of 5.31 mg/KOH with carbon adsorbent, saponification number of 139.46 mg/KOH.
