Creativity is regarded as essential for work, thinking, and life in the twenty-first century. Teaching solar cells can influence and encourage students' creative thinking skills. This research aims to evaluate the creative thinking skills of Indonesian students, validate the innovative thinking skills test adapted for Indonesia, and classify the difficulty level of the questions and students' creative thinking skills. The participants were 32 students from 10th-grade high school at a college in Bandung, West Java, Indonesia. The creative thinking skills test consists of essay questions. Data collection was carried out through paper-based tests. The results of the Rasch analysis show that the adapted creative thinking skills test meets the validity and reliability criteria based on Rasch parameters. Differential item function (DIF) analysis shows that only two of the 12 items fall into the bias question category, so they need to be reviewed. The study's implication can help teachers and researchers anticipate student success rates in disciplines other than mathematics and science. This is because creative thinking skills must be included in the Merdeka curriculum

The study aims to determine the effect of variations in the concentration of tamarind and winged bean bio coagulant concentrations on turbidity sensor SKU: SENO189 and SENO244 Gravity analog TDS Sensor TDS based ArduinoTM for educational purposes. The work started with 1) the development of a measuring device with the microcontroller ArduinoTM, 2) sample preparation, and 3) sample measurement. The water quality measurement parameters are turbidity, TDS level (dependent variable), and concentration of tamarind and wingan seeds extract (independent variable). The results showed that variations in the doses of tamarind and winged bean seed extracts of 3g/0.5L, 5g/0.5L, 7g/0.5L, and 9g/0.5 reduced the turbidity and could reduce TDS values in river water. However, the most optimal dose to reduce the turbidity value and TDS value is the addition of a coagulant at a concentration of 3 g/0.5 L with a reduction in turbidity of 71.33% (tamarind seeds) and 63.17% (wingan seeds). Then the TDS reduction value was 15.58% (tamarind seeds) and 9.54% (wingan seeds). This is because tannin compounds in tamarind and winged bean seeds can precipitate protein content between molecules in peat water that do not bind to colloidal particles, forming bonds that settle quickly

Bone fractures are rising worldwide due to aging populations and increased trauma, creating demand for implants that overcome infection, delayed healing, and poor osteointegration. Multifunctional biomaterials, especially PLA–HA Bioxcrew systems, offer integrated mechanical support with antibacterial, anti-inflammatory, and osteogenic functions while remaining biocompatible. Implant-associated infections driven by Staphylococcus aureus and Gram-negative bacteria persist because of biofilm formation and chronic inflammation. Bioxcrew advancements address these barriers through metal-ion doping, nanoscale surface engineering, and incorporation of antimicrobial agents into biodegradable polymer matrices, enabling controlled ion release, immune modulation, stem-cell recruitment, and improved bone regeneration. Stainless steel provides strength, hydroxyapatite enhances biological integration, and PLA enables safe degradation and localized drug delivery, making their hybridization ideal for next-generation implants. Using a narrative–integrative review of peer-reviewed literature from 2018 to 2025, this study synthesizes trends in antibacterial strategies and regenerative performance. Findings show that hybrid Bioxcrew platforms significantly reduce infection risk and enhance functional bone healing.
