Abstract

The limitations of conventional distillation technology hinder micro, small, and medium enterprises (MSMEs) from producing herbal products with consistent quality. This study aims to develop an Arduino-based distillation system equipped with automatic temperature control to improve the production capacity and quality of herbal liquid smoke at CV Moga Permata Perkasa. The research methods include system design and fabrication, functional testing, operator training, and performance evaluation. The results demonstrate a 35% increase in production capacity and stable temperature control within a ±2°C range during the distillation process. These findings indicate that the developed system effectively enhances production efficiency and product consistency. Furthermore, the proposed technology is affordable, easy to operate, and has strong potential for implementation and replication among similar MSMEs.

Abstract

Low rank coal (LRC), due to its abundance and carbon richness, represents a promising and sustainable precursor for graphene synthesis. This study compares the effects of different solvents CTAB (2%), NaOH (1N), H₂SO₄ (1N), and isopropyl alcohol (IPA)—on the exfoliation efficiency of LRC using a multi-stage ultrasonication approach. The resulting materials were characterized by FTIR, SEM, TEM, and XRD to evaluate their structural, morphological, and chemical properties. The findings reveal that IPA provides the most effective exfoliation, yielding few-layer graphene (FLG) with minimal oxidation and structural distortion. FTIR spectra showed reduced hydroxyl and carbonyl peaks in IPA-treated samples, while SEM and TEM confirmed more open and less-stacked layers. XRD analysis indicated decreased crystallinity and larger interlayer spacing. These results demonstrate that solvent selection plays a critical role in determining exfoliation performance, with IPA emerging as the most efficient and environmentally friendly medium for graphene production from LRC.
