Abstract

The sun's ultraviolet radiation causes erythema, premature aging, sunburn, hyperpigmentation, inflammation, and dry skin. For this purpose, sunscreen with an SPF value of over 15 is needed to protect the skin against UV rays. Breadfruit peel containing flavonoids may protect against free radicals and UV radiation. This study aims to increase SPF value from breadfruit fractionate by combining niacinamide and alpha-tocopherol. The ABTS and BSLT methods were used to screen potent free radical scavengers in n-hexane, dichloromethane, ethyl acetate, and methanol extracts. The dichloromethane extract had the highest potential as a free radical scavenger, with IC50 20,90 more or less 0,54, and the lowest toxicity, with LC50 234,42 more or less 1,06. Then, the scavenging activities and selective index of fractionates of dichloromethane were evaluated to show that the DM2 fraction had the strongest free radical scavenging activity and the lowest toxicity, with the highest selective index value of 46.08. The main active ingredient was DM2, combined with niacinamide and alpha-tocopherol into five compositions. The results of the lotion dosage forms revealed that the fifth formula, F5, met the requirement SNI standards and was stable during storage, with an SPF value of 20.61 more or less than 0.75, which was three times higher than the positive control with an SPF value of 6.67 more or less 1.28.

Abstract

Silver nanoparticles have demonstrated significant antibacterial efficacy against Escherichia coli and Staphylococcus aureus.  using a green synthesis method with plant extracts rich in flavonoids as bioreductor.  The pigeon orchid (Dendrobium crumenatum Sw.) is a plant with potential as a bioreductant, especially its stem, rich in flavonoid compounds. Optimizing heating temperature, extract volume, and silver nitrate concentration is essential for producing silver nanoparticles with optimal properties and enhanced antibacterial activity.  This research conducts optimization by varying the volume of pigeon orchid stem extract, heating temperature, and AgNO3 solution concentration.  The main parameter in the optimization is the Surface Plasmon Resonance (SPR) value. The characterization of silver nanoparticles includes particle size, polydispersity index, zeta potential, FTIR spectra, and antibacterial activity tests against E. coli and S. aureus. The research results show that the optimum conditions for synthesising silver nanoparticles are 1 mL of orchid stem extract, a heating temperature of 60°C, and an AgNO3 concentration of 1.629 mM..  The silver nanoparticles produced have characteristics with an SPR peak at 450 nm, a particle size of 98.267 nm, a polydispersity index of 0.2337, and a zeta potential of -21.9 mV.  Antibacterial tests showed an inhibition zone of 14,71±1,23 mm against S. aureus and 15,28±0,91 mm against E. coli.  These results prove that silver nanoparticles effectively inhibit the growth of gram-positive and gram-negative bacteria.

Abstract

The integration of local wisdom in physics learning remains limited, and no module simultaneously combining the Arakan Sahur tradition, robotics technology, and the STEM approach has yet been developed. This study aimed to develop a straight-motion learning module using robotics based on Arakan Sahur miniatures integrated with STEM and to analyze its feasibility in terms of content quality, presentation, usability, and implementation in learning activities. The study employed the Research and Development (R&D) method using the Borg and Gall model limited to five stages. Data were collected through material expert validation questionnaires, media expert validation questionnaires, teacher perception questionnaires, student response questionnaires, and interviews. The feasibility indicators included material relevance, language clarity, content presentation, STEM integration, self-instructional characteristics, stand-alone usability, and user-friendliness of the module. The results showed that material expert validation achieved an average score of 3.47 (very good), while media expert validation reached 3.50 (very good) after two rounds of revision. Teacher perceptions obtained an average score of 3.44 (very good), and responses from 22 students reached 3.55 (very good). The module also demonstrated explicit implementation of the four STEM components through robotics programming, motion analysis, engineering design, and mathematical calculations. In addition, 95.5% of students showed high interest in learning physics using robotics-based activities. In conclusion, the developed module is considered valid and practical for use in high school physics learning and contributes as an innovative teaching material integrating physics concepts, local culture, robotics, and STEM learning.
