Abstract

Black pepper is one of Indonesia's agricultural commodities, contributing foreign exchange to the country. However, the economic value of this commodity has decreased. It is influenced by the lack of diversified black pepper products, which of course, have a higher value than raw material marketing. One product diversification that can be developed is black pepper oil. In obtaining essential oils, appropriate methods and technology are needed so that the resulting product is of high quality and the process is carried out efficiently. The latest methods in extraction that are being developed are microwave and ultrasonic technology. Therefore, in this study, black pepper oil extraction was carried out using the microwave hydrodistillation method, whereas previously, ultrasonic pretreatment was given for the material. In this case, observations were made on the influence of extraction parameters. Based on the research, it was found that increasing the distiller size flask and ambient temperature could increase the percentage of essential oils yield. At the same time, the longer extraction time caused a decrease in yield. Decreasing the material particle size and increasing microwave power could cause an increase in yield up to a certain point. The best results in black pepper oil extraction were obtained under extraction conditions using a distiller size of 1000mL, extraction time of 60 minutes, at an ambient temperature of 30 oC, the particle size of 60 mesh, at a power of 450 W with a yield of 1.056%, with the characteristics of having a clear greenish colour and anRI of 1.480. These specifications comply with ISO 3061:2008 for essential oil from black pepper. Thus, these parameters can be considered in the black pepper oil extraction process to produce marketable products. As a suggestion for further research, modeling, and process scale-up can be developed.

Abstract

This research investigates the fabrication and characterization regarding silver nanoparticles (AgNPs) utilizing essential oil derived from citronella leaves (Cymbopogon nardus L.) as a bioreductant. The synthesis method employed is sonochemistry, with variations in pH levels to determine optimal conditions for AgNPs yield. The use of essential oil as a bioreductant offers eco-friendly advantages and high efficiency in reducing metal ions. The results indicate that the highest yield of 8.67% was achieved at pH 9.0280 and 59.7190 minutes of sonochemical processing. Statistical optimization of processing parameters was conducted to maximize the yield of AgNPs, with the optimization process analyzed using Response Surface Methodology (RSM). The sequence of experimental runs, condition variations, and obtained results were determined using the Central Composite Design (CCD). The model demonstrates a strong correlation with the experimental data, exhibiting an adjusted R² value of 0.9684. A high F-value of 30.61 and a low p-value of 0.0009 suggest that the regression model is statistically significant and effectively accounts for variations in AgNPs yield. The lack-of-fit value for the model is 0.0359, indicating no significant discrepancy between the experimental data and the model's predicted values. The successful formation of AgNPs was confirmed, with absorption peaks observed within the 400–450 nm range.
