Abstract

The development of natural additives in metal electrodeposition processes has emerged as a promising alternative. This study evaluates the role of aqueous extract of sengon leaves (Albizia falcataria) as an additive in the zinc electrodeposition process on iron plates. The plating was carried out in a zinc chloride electrolyte solution with variations in current density and deposition time. Observed parameters included surface morphology, coating mass, and thickness. The results showed that the addition of sengon leaf aqueous extract improved the coating quality by producing a smoother and more uniform surface. The active compounds in the extract are presumed to act as wetting agents, aiding the growth of zinc crystals. This study indicates that sengon leaf aqueous extract has potential as an alternative additive in the zinc electrodeposition process.

Abstract

Public interest in e-cigarettes in Indonesia has increased significantly in recent years. This was initially driven by claims that e-cigarettes as an alternative tool to help individuals quit conventional smoking. However, this product is increasingly attracting teenagers and people who did not previously smoke. This trend is largely due to the composition of e-liquids used in e-cigarettes, which often formulated with flavor compounds such as vanillin, menthol, and various fruit flavors that significantly enhance the sensory characteristics and consumer acceptability of the products. Many of these flavoring compounds are commonly used in food products with regulated limits. However, the toxicological effects of flavoring compounds in inhalation and the maximum exposure limit have not been comprehensively investigated. Moreover, the presence of nicotine as an addictive substance in e-cigarettes can encourage continuous use, consequently increasing the frequency and duration of exposure to flavoring compounds. These conditions raise concerns about potential health risks, particularly among youth who are frequently identified as active users. Therefore, this study aims to determine the concentration of vanillin, one of the most frequently detected flavoring compounds in e-liquids. The analyzed samples include vanilla, mango peach, and banana cream berry flavor variants. The concentration of vanillin was quantified using gas chromatography with Flame Ionization Detector (GC-FID). The analytical method was validated using several parameters, including precision, accuracy, linearity, LOD, and LOQ. The results showed that the concentration of vanillin detected in the three analyzed e-liquid samples were 8.36mg/mL, 2.04mg/mL, and 1.28mg/mL, respectively. The findings indicate that vanillin, commonly associated with sweet flavor profiles, was also identified in e-liquids labeled as fruit-flavored. These results highlight the widespread use of flavoring additives in e-cigarette products and emphasize the importance of monitoring their presence due to potential implications for public health.

Abstract

This study presents a sustainable approach for synthesizing calcium peroxide (CaO₂) nanoparticles from biogenic eggshell waste as a potential adsorbent for wastewater treatment. Increasing water pollution caused by industrial and domestic activities has driven the demand for low-cost and environmentally friendly adsorbents. In this study, eggshells from various poultry sources were calcined at 900°C to produce CaO, followed by hydration and chemical precipitation using H₂O₂ to synthesize CaO₂. The resulting materials were dried at different temperatures (60–100°C) to evaluate the effect of thermal treatment on structural properties and adsorption performance. X-ray diffraction (XRD) analysis confirmed the formation of CaO₂ with nanoscale crystallite sizes ranging from 15.3 to 28.85 nm. Brunauer–Emmett–Teller (BET) analysis showed specific surface areas between 10.18 and 19.67 m²/g. Adsorption experiments using acetic acid revealed that performance was significantly influenced by precursor type and drying temperature. The highest adsorption capacity (347.54 mg/g) and removal efficiency (34.75%) were achieved using CaO₂ derived from free-range chicken eggshells at 80°C. This enhanced performance is attributed to the natural biogenic structure, mineral composition, and pore distribution. Overall, eggshell waste is a promising, sustainable, and cost-effective precursor for producing high-performance CaO₂ nanoparticles for wastewater treatment
