In the era of globalization and technological developments, students are required to have critical thinking skills and competencies, problem solving skills and the ability to think creatively. This article discusses the application of Project-Based Learning as an effective strategy in improving students' creative thinking abilities in the Network Systems Administration course, even semester January-June 2023, Padang State University's Informatics Engineering study program. The research design used was Quasi Experimental, involving two class groups, each an experimental class and a control class. This research produced findings that showed significant differences in increasing creative thinking skills between the experimental class and the control class. This difference can be seen from the results of the N-gain test (0.006 < 0.05), which shows that the average increase in creative thinking skills in the experimental class is higher than in the control class. Analysis per indicator shows that the increase in N-gain in the experimental class in the Fluence and Flexibility indicators is in the high category, while the Originality and Elaboration indicators are in the medium category. This finding is supported by the higher level of learning activity in experimental class students compared to the control class. Apart from that, positive responses from students regarding the implementation of the project based learning model can also be seen from the results of the questionnaire instrument.Keywords: Network System Administration, Creative Thinking Ability, Project-Based Learning

Red dragon fruit (Hylocereus polyrhizus) is known for its strong antioxidant properties and potential anti-aging effects. To enhance its benefits and improve usability, this fruit extract was formulated into a gel preparation. This study aimed to determine the optimal proportions of Carbopol 940 and triethanolamine (TEA) to obtain a gel with desirable physical characteristics. The flesh of red dragon fruit was juiced and concentrated to produce an 8% extract. Three formulations were prepared with varying ratios of Carbopol 940 to TEA: 0.5%:0.3% (F1), 1.2%:0.7% (F2), and 2%:1.2% (F3). The gels were evaluated for physical properties, antioxidant activity, and antibacterial activity. The most promising formula was subjected to stability testing for three cycles under different temperature conditions: cold (3°C), room temperature (27°C), and climatic chamber (40°C, 75% RH). Results showed that formula F2 exhibited a characteristic red color, clear appearance, distinctive oleum rosae aroma, moderately thick and homogeneous consistency, viscosity of 3112.47 ± 177.90 cps, spreading diameter of 5.20 ± 0.20 cm, adhesion time of 18.45 ± 0.89 s, and pH of 5.33 ± 0.02. No significant changes were observed after the stability testing (p > 0.05), indicating that the formulation remained stable under all temperature conditions. F2 also showed higher antioxidant activity than F1 and better antibacterial properties than F3. Its stability and bioactivity support its potential as a promising natural cosmeceutical formulation.
