Abstract

Red ginger is known as one of the medicinnal and aromatic plants that have high value in the form of essential oils. The distillation of red ginger essential oils required large amounts of water, and then most of the water was disposed of as wastewater. This wastewater is known as hydrosol, which still contains a small amount of essential oils and secondary metabolites such as zingiberene and geraniol. These compounds were considered to have the potential to be utilized in cosmetic products such as foot sanitizers. The aim of this study was to evaluate a foot sanitizer product based on red ginger hydrosol that combined with coffee extracts based on its antibacterial activity against Staphylococcus aureus and the physical characteristics of the product. Foot sanitizer was produced in three formulations with different concentration (in percentage) of red ginger hydrosols and coffee extracts consist of F1 (45:25), F2 (35:35), and F3 (25:45). The results showed the F3 formulation provided the largest antibacterial inhibition (2.89±0.60 mm) compared to other formulations. The F3 formulation has a physical characteristics such as coffee scent aroma, a dark brown color, a pH of 5.5, a density of 960.73 kg/m3 and has a weak antibacterial activity. Based on the comparison results with previous studies, the utilization of coffee extracts in red ginger hydrosols-based foot sanitizer needs to be substitued with other natural extracts, especially having a strong antibacterial activity. It should be carried out to increase the potential value of valorizing red ginger hydrosols as foot sanitizer.

Abstract

Various weeds in paddy rice fields could be utilized as natural polyphenols sources, one of them was kitolod (Hippobroma longiflora (L.) G.Don). Kitolod was widely utilized as traditional medicine by several community groups because of its polyphenols content. Recent trends showed kitolod could be valorized as additive matters in sunscreen products. Polyphenols content, especially flavonoids were able to absorb dangerous spectrum in sunray radiation and it is related to sunscreen activity. This study aimed to evaluate the differences in simplicia treatments and extraction techniques towards total polyphenols content and sunscreen activity on kitolod leaf extracts. Solvent-cold extraction techniques were deployed in this study that consist of water infusion and ethanolic maceration for 24 hours at ambient temperature. Extracts were analyzed by spectrophotometric measurement to determine total phenolics content (TPC), total flavonoids content (TFC), and sunscreen activity by deploying Folin-Ciocalteu assay, AlCl3 colorimetric assay, and Mansur approached assay, respectively. Dry kitolod leaves were extracted by ethanolic maceration techniques provided high yields (15.5±0.3%), high TPC (17.9±0.3 mg GAE/g of solids), high TFC (25.9±0.4 mg QE/g of solids), and moderate sunscreen activity (SPF 11.0±0.1). The results indicated kitolod could be valorized as natural polyphenols sources and additive matters in any cosmetical sunscreen products.

Abstract

Hydrodistillation is widely known as the simplest essential oils (EOs) isolation technique and is widely used by small-scale producers, such as in Indonesia. The main characteristic of hydrodistillation is the plant-source material of EOs soked in water, followed by boiling and diffusion. Variuos problems arise from the use of hydrodistillation, including the possibility of overheating, degradation of EOs because of the long heating time, difficulty in controlling the heat, and a slow process. The aim of this study was to review the recent developments in hydrodistillation technology that have been developed in Indonesia to improve the quality and yield of EOs. Bibliometric analysis trhough the Methodi Ordinatio was used to compile a systematic review of prior studies in the recent decade regarding the application of hydrodistillation in Indonesia. The results showed that five plant-source commodities were extensively isolated consisting of citrus, lemongrass, cinnamon, nutmeg, and ginger. Furthermore, this study investigated the variables that influnce the hydrodistillation process for EOs isolation. The variables were often evaluated according to the results are distillation time, pretreatment of raw materials, feed-to-solvent ratio, particle size, growth place, and plant developmental stage. A future perspective was considered and outlined to carroed out further novel study and development strategies.

Abstract

The use of starch as a binder in biomass briquette production raises concerns regarding food security, prompting the need for alternative, non-food-based binders. This study aimed to develop carboxymethyl holocellulose (CMH) derived from oil palm empty fruit bunches (OPEFBs) as a sustainable and effective binder for biomass briquettes made from coconut shells and sawdust. The OPEFBs were converted into CMH through a carboxymethylation process, yielding a product with a carboxyl content of 12.81% and a degree of substitution (DS) of 0.40, indicating effective modification. The synthesized CMH was used as a binder at various concentrations, with citric acid (CA) employed as a crosslinking agent. The total carboxyl content significantly increased with higher CA concentrations, demonstrating improved functional properties. Briquettes produced using CMH exhibited favorable proximate characteristics, such as low moisture content, high fixed carbon, and enhanced calorific value, particularly for coconut shell-based briquettes. The findings suggest that CMH can serve as an alternative to starch, providing sustainable and environmentally friendly solutions for biomass briquette production. Future studies should focus on optimizing the synthesis process and exploring CMHs’ performance in diverse biomass formulations.
