Abstract

Most of the area in Jabung Village, Pelupuh, Sragen is paddy fields, with most of the population's livelihood being farm workers and convection business. However, during the Pandemic, the convection business was sluggish and slumped. This makes the people of Jabung village need other alternative businesses to increase their income. The amount of agricultural land in Jabung village, which produces rice husk waste, can be an alternative for new businesses for the community. Based on the research results of the Research Group (RG) at the Chemistry Education Study Program, UNS, rice husks can be made as activated charcoal, which is used to purify used cooking oil. The purified cooking oil can be used to make biodiesel, soap and aromatherapy candles. Therefore, the community service team of the Chemistry Education Study Program has provided training on the manufacture of activated charcoal from rice husks and its use for purifying used cooking oil as a provision for business in Jabung Village. Attended by 60 participants, this training focused on three main activities; educating the community about the process of absorption by activated charcoal, purifying used cooking oil using activated charcoal from rice husks, and marketing processed products from used cooking oil and activated charcoal. The results of the evaluation of this training, as many as 36.73% of participants strongly agree, and 53.06% agree that the community gets direct benefits from training activities on making activated charcoal from rice husks and its use for cleaning used cooking oil.

Abstract

The challenge of developing environmentally friendly synthesis methods for biologically active compounds remains a significant focus in green chemistry. This study aimed to synthesize 4'-hydroxy-4-nitro chalcone from 4-hydroxyacetophenone and 4-nitrobenzaldehyde using a grinding technique and then characterize the synthesized compounds. The 4'-hydroxy-4-nitro chalcone was synthesized via the Claisen-Schmidt grinding method for 45 minutes at room temperature. The grinding results were extracted with chloroform. The formed crystals were tested for purity by thin-layer chromatography (TLC), and further purification was carried out by recrystallization. The synthesized chalcone was characterized using FTIR, 1H-NMR, and 13C-NMR  spectroscopy. The chalcone was also tested for antibacterial activity using the disc diffusion method against Staphylococcus aureus and Escherichia coli. The results showed that 4'-hydroxy-4-nitro chalcone could be successfully synthesized from 4-hydroxyacetophenone and 4-nitrobenzaldehyde using the grinding technique, yielding orangish-white crystals with a 70.63% yield and a melting point of 173°C. Purity was confirmed by TLC, and structural characterization was achieved through FTIR, 1H-NMR and 13C-NMR spectroscopy. Antibacterial testing revealed that the synthesized chalcone produced a clear zone diameter of 9.27 mm against S. aureus and 27.88 mm against E. coli. These results indicate that the compound has relatively strong antibacterial activity against E. coli and relatively weak activity against S. aureus. This study demonstrates the effectiveness of the green synthesis method and provides valuable insights into the antibacterial properties of 4'-hydroxy-4-nitro chalcone

Abstract

Various brands and forms offer a wide array of cream-based cosmetic products. However, only some of these products meet safety specifications. Aloe vera and nutgrass, two plants rich in bioactive compounds, possess anti-inflammatory, soothing, and antibacterial properties, making them ideal for health-safe cosmetic formulations. This research was conducted to develop antibacterial cream formulations incorporating these natural additives. The study focused on quality, organoleptic testing, and the formulated cream's antibacterial assessment. The research methodology encompassed several key processes: preparation of Aloe vera gel and nutgrass rhizome ethanol extract, formulation of the cream, quality testing by SNI 16-6069-1999 standards, organoleptic testing as per SNI 01-2346-2006, and antibacterial activity testing using Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 bacterial strains. Results indicated that the cream formula enriched with Aloe vera gel and nutgrass rhizome ethanol extract meets the standards for skin-lightening creams and exhibits significant antibacterial capabilities. Furthermore, it was observed that the antibacterial effectiveness of the cream increases with the concentration of the nutgrass rhizome ethanol extract. These findings highlight the potential for integrating natural ingredients into modern cosmetic formulations, providing therapeutic and aesthetic benefits. This approach not only ensures compliance with safety standards but also leverages the natural properties of Aloe vera and nutgrass to enhance the product's functionality in skin care applications

Abstract

This study aimed to analyze the chemical components and antibacterial activity of essential oils from kamboja (Plumeria alba L.), sedap malam (Polianthes tuberosa L.), and kenanga (Cananga ordorata L.) flowers against Staphylococcus aureus ATTC 25923. Additionally, the study explored the application of these essential oils as bio additives in transparent solid bath soap. The research consisted of several stages: isolation and identification of chemical components of essential oils using the GC-MS Method, transparent solid bath soap formulation, antibacterial activity test of essential oils and transparent solid bath soaps against Staphylococcus aureus ATTC 25923, organoleptic test (color, aroma, transparency, solidity, and foam) and quality test of transparent solid bath soaps (pH, water content, foam stability, saponification number, and transparency). The essential oils extracted from kamboja, sedap malam, and kenanga flowers were found to contain 17, 20, and 20 compounds, respectively. Based on the result of GC-MS analysis showed that the predominant chemical components in each essential oil were 1,1’-oxydi-2-propanol (21.01%) for kamboja, benzyl ethanoate (24.52%) for sedap malam, and caryophyllene (43.77%) for kenanga. Transparent solid bath soaps with the highest antibacterial activity against S. aureus ATTC 25923 were obtained in the formula added with kamboja, sedap malam and kenanga flowers essential oils at 3.0%, 3.0%, and 3.0%, respectively, with respective inhibitory power of 14.48 mm (strong), 13.73 mm (strong) and 13.56 mm (strong) in diameter. Organoleptic tests revealed that each soap type exhibited characteristic of the respective flower. All soap types demonstrated good quality based on parameters such as pH, water content, foam stability, saponification number and transparency.

Abstract

Anthocyanins are highly coloured polyphenols, a class of flavonoids, which are natural, non-toxic, and water-soluble compounds. Because of that, anthocyanins have been used in numerous applications, such as natural colorants for foods, beverages, and textiles. However, anthocyanins have some drawbacks regarding their stability towards temperature, pH, and light, leading to degradation. One method to improve anthocyanins’ stability can be achieved through a complexation reaction of anthocyanins with metal cations. Thus, this study aimed to investigate the stability and colour profiles of anthocyanins extracted from Java Plum fruits (Syzygium cumini) complexed with Al3+, Fe3+, and Ca2+ ions in pH 1-12. Previously, anthocyanins from Java Plum fruits have been identified by LC-MS as cyanidin-3-O-glucoside ([M]+, m/z 449.3), delphinidin-3-O-glucoside ([M]+, m/z 465.3), and petunidin O-glucoside ([M]+, m/z 479.3). The ATR FTIR was also performed to confirm the functional group of anthocyanins. The colour of each solution at different pH was evaluated by UV-Vis Spectrophotometer at 200-800 nm. Complexation of anthocyanins with Al3+, Fe3+, and Ca2+ ions showed various colours at different pHs. The complexation of anthocyanins with Al3+ at pH 4-5 developed a blue colour. The intensity of the blue colour increases with an increase in Al3+ ion concentration. This investigation showed the potential application of anthocyanin-metal chelation for the textile industry due to the range of colour produced. Furthermore, the complexation of anthocyanins to produce blue colour can be an alternative in food industries as this colour is difficult to obtain in acidic pH.

Abstract

ABSTRACT. In the past 5 years, research has reported that chemical sunscreen products pose risks of irritation and environmental impact, necessitating safer natural alternatives, such as eco-friendly sunscreen. This study aimed to formulate a natural sunscreen by combining Aloe vera gel with garlic-shallot peel waste extracts and evaluate their solar protection factor (SPF), physical stability, overall quality, and organoleptic-hedonic test. The Aloe vera and extracts of garlic and shallot peels were prepared using modified infusion and solvent extraction techniques. The sunscreen formulas were created in nine variations with different concentrations of natural ingredient combinations. SPF values were determined in vitro using UV/Vis spectrophotometry, and the physical stabilities were tested using the cycling method. Overall quality tests were performed using the method as described in the standard and requirements for sunscreen products in Indonesia (SNI 16-4399-1996), and the procedure for determining the organoleptic-hedonic test referred to the organoleptic and/or sensory testing instructions (SNI 01-2346-2006). The results showed that all nine formulations met most of the quality standards of sunscreen. However, the panelist preferred formulas without garlic and shallot extracts due to the prominent odor of garlic and shallot. Further studies will be performed by combining them with fragrances that panelists prefer to cover the deficiencies in unpreferred odors. Formulas with garlic and shallot peel extracts have ultra-protection SPF values, though their effectiveness decreased with increased Aloe vera concentrations. These results indicate that garlic and shallot peel waste have the potential as sustainable, environmentally friendly sunscreen ingredients with high UV protection capabilities. Keywords: Aloe vera, garlic peel, shallot peel, SPF, sunscreen
