Abstract

One of the villages that already has a Memorandum of Understanding (MoU) as a fostered village of Jember University is Sidomekar Village located in Semboro District, Jember Regency, East Java. The problem of Sidomekar Village that is highlighted is the low selling price of Semboro oranges during the harvest season, sometimes only Rp2000 per kg, thus negatively impacting farmers' income. The solution to this problem is to utilize orange peel waste as an active ingredient in body scrub preparations so that it can be used as one of the village's superior products. This community service program aims to provide solutions to the problems faced by partners while increasing the Village Development Index, especially in terms of the Economic Resilience Index through the development of superior village products based on orange peel waste. This service program was carried out by providing socialization attended by 35 participants regarding the process of making and using tools to produce body scrubs from orange peels. The increase in knowledge and skills of participants increased by 90% based on the active participation in the socialization event during the question and answer session and practice of making body scrubs from orange peels.

Abstract

Nitrogen recovery from wastewater is capable of preventing eutrophication, offering economic benefits, and reducing carbon footprint from synthetic fertilizer production. Biochar has been explored as adsorbent for ammonium (NH??) removal. Therefore, this study aimed to investigate the potential of biochar derived from cocopeat as adsorbent for NH?? removal. Cocopeat was modified by potassium hydroxide (KOH) and pyrolyzed at 500°C for 2 h to produce activated biochar. Kinetics and isotherm studies were conducted to examine adsorption mechanisms. Fourier Transform Infrared (FTIR) data showed that the resulting biochar after activation and adsorption contained hydroxyl O–H and C–O groups, while a new N–H band confirmed the interaction with NH?? ions. Biochar adsorbed NH?? ions with a maximum capacity of 0.3078?mg/g. FTIR spectra showed shifts and changes in the intensity of functional group bands, confirming the interaction between NH?? ion and the active sites on biochar surface. Adsorption followed Langmuir isotherm and pseudo-first-order kinetics model, with an optimal contact time of 5 h. These results suggested that cocopeat-based biochar had potential as an effective NH?? adsorbent.

Abstract

Ulva lactuca merupakan biota laut yang berpotensi sebagai sumber bahan aktif kosmetik karena kandungan bioaktifnya seperti flavonoid, alkaloid, saponin, terpenoid, dan tanin. Penelitian ini bertujuan mengekstraksi flavonoid serta menganalisis nilai Sun Protection Factor (SPF) U. lactuca menggunakan kombinasi metode cell disruption dan ultrasound-assisted hot water (UAHW). Tiga metode perlakuan cell disruption (tanpa perlakuan, osmotic shock, dan hidrotermal dengan autoklaf) dikombinasikan dengan variabel UAHW yaitu suhu ultrasonik (40, 60, 80 °C) dan waktu ultrasonik (5, 10, 15 menit). Ekstraksi dilakukan menggunakan pelarut etanol 96% pada serbuk U. lactuca berukuran 60 mesh. Optimasi dilakukan menggunakan Response Surface Methodology (RSM) dengan Box–Behnken Design (BBD). Hasil menunjukkan bahwa total flavonoid dan nilai SPF tertinggi (33,23 mg QE/g dan SPF 20,80) diperoleh tanpa perlakuan cell disruption, pada suhu 80 °C dan waktu ekstraksi 10 menit. Penelitian ini menegaskan bahwa metode UAHW efektif meningkatkan ekstraksi flavonoid dan SPF meskipun tanpa cell disruption. Selain itu, pendekatan RSM terbukti efisien dalam optimasi proses. Studi ini memberikan kontribusi pada pengembangan bahan aktif alami U. lactuca untuk aplikasi kosmetik, khususnya sebagai agen pelindung sinar UV.Optimization of Flavonoid Extraction from Ulva lactuca Using a Combination of Cell Disruption and Ultrasound-Assisted Hot Water. Ulva lactuca is a marine organism with significant potential as a source of active ingredients for cosmetic applications, owing to bioactive compounds such as flavonoids, alkaloids, saponins, terpenoids, and tannins. This study aimed to extract flavonoids and evaluate the Sun Protection Factor (SPF) of U. lactuca using a combination of cell disruption methods and ultrasound-assisted hot water (UAHW) extraction. Three cell disruption treatments (no treatment, osmotic shock, and hydrothermal using an autoclave) were combined with UAHW variables, including ultrasonic temperature (40, 60, 80 °C) and ultrasonic time (5, 10, 15 minutes). The extraction was conducted using 96% ethanol as a solvent on U. lactuca powder sieved to 60 mesh. Optimization was performed using Response Surface Methodology (RSM) with a Box–Behnken Design (BBD). The highest total flavonoid content (33.23 mg QE/g extract) and SPF value (20.80) were obtained without cell disruption, at 80°C for 10 minutes. The study confirms that UAHW effectively enhances flavonoid extraction and SPF, even without cell disruption. Furthermore, the RSM approach proved efficient for process optimization. This study contributes to developing natural active ingredients from U. lactuca for cosmetic applications, particularly as UV-protective agents.

Abstract

Quantitative structure-activity relationship (QSAR) has been studied for ferulic acid derivatives to determine the QSAR model able to predict anticancers. The subject of this research was a set of experimentally calculated IC50 value data of 6 ferulic acid derivatives against cervical cancer cells (HELA). QSAR analysis was based on multilinear regression calculation on fitting subset using log (1/IC50) as the dependent variable, and dipole moment, partition coefficient in the n-octanol/water, and atomic net charges of the aromatic carbons as independent variables. The values of the descriptors were obtained from semi-empirical PM3 quantum mechanics calculation. The relationship between log (1/IC50) and the descriptors was described by the result in the QSAR model. The QSAR model for ferulic acid derivatives against HELA cell lines was developed with the statistical parameters of R=0.998; R2=0.999; SE=0.00857;  and F=394. The calculated log (1/IC50) using the QSAR Hansch Model for ferulic acid derivatives has excellent agreement with the experimental data of Log (1/IC50).

Abstract

Dragon fruit skin contains 26.4587 mg/L anthocyanins. Anthocyanins have benefits such as natural coloring agents in the food sector and are used as an alternative to synthetic dyes which are of course also safer for health. The purpose of this study was to determine the effect of extraction variables (time, solvent concentration, and particle size) on the anthocyanin content of dragon fruit skin from the extraction results with the Solvent Extraction method. The definition of Solvent Extraction is the separation of materials from a solid or liquid with the help of a solvent. The extraction process starts from the agglomeration of the extract with the solvent then contact occurs between the material and the solvent so that on the flat plane of the interface of the extraction material and the solvent there is mass deposition by diffusion. The extraction process starts with 25 grams of dragon fruit peel powder with a variety of particle sizes (30, 60, and 80 mesh) then put into an Erlenmeyer tube. Then, the citric acid solution with various concentrations (0.1 M; 0.2 M; and 0.3 M) was added as much as 250 ml. After that, the Erlenmeyer was placed on a stirrer to stir for (90, 120, and 150 minutes). After that, the extraction results were filtered using filter paper to produce a filtrate. Then the filtrate was precipitated to obtain anthocyanin extract. After that, it was analyzed using the spectrophotometric method to calculate anthocyanin content. In this study, the best results were obtained at 11.439 mg/L in conditions without repetition. The optimum conditions of extraction were obtained at a particle size of 60 mesh, a time of 150 minutes, and a solvent concentration of 0.5 M citric acid.
