“…Because it is located next to the product information, this image signifies the meaning of safe. According to Savitskaya (2021), the symbol of a wine glass and a fork is an international symbol of 'safe food'. The symbol indicates that the packaging of the product is considered safe for direct contact with the food.…”

This study aims to identify semiotic signs present on the packaging of Nata de Coco. Utilizing a qualitative approach, the research draws upon Saussure's signifier and signified theory as outlined by Chandler (2022). Through analysis, ten semiotic signs were identified on the packaging, including the overall design, company logo, Wonderful Indonesia logo, Superbrands logo, Top Brand logo, Halal MUI logo, Mr. Mutu logo, International Food Safe symbol, International Resin Identification (7 other) Code symbol, and Do Not Litter icon. These findings shed light on the symbolic elements utilized in packaging design and their significance in communicating messages to consumers.

“…Microwave-assisted exfoliation facilitates rapid synthesis of GQDs with high yields and reproducibility, alongside control over size, morphology, and properties through adjustable parameters [40], while employing eco-friendly solvents to minimize environmental impact; however, scalability may be limited due to reactor throughput and precise parameter control requirements, with risks of overheating and dependency on specialized equipment [41]. Applications span biomedical imaging for fluorescence and bioimaging, sensing platforms for various analytes, and energy conversion/storage in supercapacitors, batteries, and solar cells, leveraging GQDs' optical, electronic, and electrochemical properties [42].…”

“…31 Palladium and palladium-based catalysts are attaining popularity for their use as catalyst and fuel cell appliances due to their lower price and better activity than Pt containing rare earth metals. [32][33][34][35] As a result, the efficiency and operation of the Pd catalyst must be enhanced. Due to the diverse properties of different components, combining Pd with an abundant and cheap element is an effective way to boost electrocatalytic activity or synergic effects, 36 and this will also help to reduce the band gap of ZrO 2 which is crucial for electrocatalytic performance.…”

Summary Semiconducting metal oxide nanostructures have the potential to play a significant role for introducing a new podium for alternative energy technologies, such as energy storage and conversion via photovoltaic array, solar fuels, and water electrolysis. To be able to build high‐performance fuel cells and electrocatalysts to meet energy demand, it is critical to develop abundant and cheap electrocatalysts to address fossil fuel reduction and the energy crisis. Current study reports the first investigation on nanocomposite of Zirconia and palladium oxide (ZrO2@PdO) as an electrode material synthesized by a biomimetic approach. Biosynthesized ZrO2@PdO nanocomposites had direct band gaps of 4.5 and 3.5 eV, as measured by ultraviolet spectrophotometry capped by organic functional groups as revealed by Fourier‐transform infrared spectroscopy. Formation of oxide nanoparticles was confirmed through UV‐Vis spectroscopy with peaks exhibition between 300 and 400 nm. Polycrystalline phase patterns were determined by x‐ray diffraction with average crystallite sizes of 12 nm. Scanning electron micrographs of nanocomposites revealed granular and uniform grain shapes, with strong signals for Zr, Pd, and O exposed by energy dispersive x‐ray spectroscopy. X‐ray photoelectron spectroscopy successfully revealed the capping of phytocompounds (C1s) as well as confirmed the composition of material with strong signals of Pd, Zr, and O1s. Electrochemical investigation included linear sweep voltammetry and electrochemical impedance spectroscopic (EIS) studies. The electrode performed well, with low overpotential value as well as Tafel slope value (64 mV/dec), signifying its effectiveness as oxidation catalyst. The Nyquist plot from EIS with an arc radius demonstrated the occurrence of resistance mechanism arising from interfacial region of electrode surface with charge transfer resistance (Rct) of only 3.23 Ω. ZrO2@PdO did not perform well for hydrogen evolution reaction under the same operating conditions, however, can be improved by optimizing the parameters. Active to electrochemical application manifested ZrO2@PdO a potential candidate for photovoltaic devices in term of economic viability and sustainability in comparison to environmentally harmful pathways.
