Abstract

Cervical cancer is the second leading cause of death in women. Many cancer treatments currently provide toxic effects on normal cells. Therefore, alternative treatment using chalcone derivatives has potent anticancer properties that can help reduce cancer side effects. Chalcone derivatives with halogen and methoxy groups in ring B can potentially inhibit cancer cells. This research aimed to synthesize halogen-substituted chalcone by a green chemistry approach and determine activity against cervical cancer (HeLa) cell lines. The Claisen-Schmidt reaction was used to synthesize 2'-hydroxy-2-bromo-4,5-dimethoxychalcone using a grinding technique. The purity of the synthesized compound was determined using thin-layer chromatography and melting range. The compounds' structures were characterized using FTIR, MS 1H, and 13C-NMR. The result showed that the synthesized compound was yielded in 53% as a yellow solid. In vitro cytotoxicity of the synthesized chalcone was evaluated by the MTT assay method. The IC50 of the compound was 67,23 μg/mL as a moderate activity inhibiting cervical cancer (HeLa) cell lines. Based on the IC50 value, this compound can be a candidate for anticancer against Cervical cancer (HeLa) cell lines.

Abstract

The corrosion of ferrous metals is a serious issue that can reduce material durability and lead to significant economic losses. Melinjo seed extract was selected for investigation due to its potential as a corrosion inhibitor, attributed to the presence of tannin compounds capable of forming complexes that coat metal surfaces. This research aims to explore the use of melinjo seed extract as a bioinhibitor for iron, providing an effective and environmentally friendly solution. The extraction of melinjo seeds was performed using the maceration method. The melinjo seed extract was mixed with 70% ethanol to obtain an inhibitor solution. The study evaluated the corrosion rate and inhibition efficiency of iron immersed in melinjo seed extract solution at varying concentration. The results showed that melinjo seed extract has the potential to inhibit corrosion in iron. A higher concentration of melinjo seed extract correlated with a lower corrosion rate. The highest corrosion rate was 6.7x10-2 g/cm² day at 0% concentration. The lowest corrosion rate was 1.6x10-2 g/cm² day at a 15% concentration of melinjo seed extract. The optimum inhibition efficiency was achieved at the 15% concentration, which amounted to 76%. These results indicate that melinjo seed extract is an effective bioinhibitor for ferrous metal corrosion.

Abstract

Many students have difficulty understanding chemistry concepts due to limited learning resources such as textbooks and traditional lectures. This research proposes making videos using Dora Toon, an audiovisual web platform specifically for petroleum materials. This project aims to assess video quality through evaluation by research subjects (material experts, media, chemistry educators, and 10 class XI high school students). With a research and development approach, the model used is 4D (define, design, development, disseminate) with a focus on the disseminate stage. The definition stage includes analysis of the front-end, students, concepts, tasks, and learning objectives. The design stages include selecting media format, collecting references, creating initial designs, and making instruments. The development stage includes video production, validation tests on research subjects. Sampling used purposive sampling technique, data collection used a validation questionnaire, and analyzed descriptively in percentages. At the disseminate stage, the product can be distributed to the wider community. However, this stage was not carried out due to time constraints. This results in HD resolution that is easy to use. It produces HD (1280x720p) resolution MP4 videos that are easy to use and contain petroleum ingredients. The evaluation results were very positive. The material expert gave a score of 95% (very good), the media expert gave a score of 95% (very good), the chemistry teacher gave a score of 86.06% (very good), and the students answered positively 100%. These findings indicate that animated videos can be an alternative learning tool for teaching petroleum chemistry in the classroom

Abstract

Tradescantia spathacea Sw. is commonly used as a traditional medicine plant to treat several diseases. This study aims to identify phytochemical constituents using phytochemical screening, quantify the total phenolic (TPC) and flavonoid content (TFC) analysis, and evaluate the antioxidant activity of various extracts via DPPH free radical scavenging activity. The phytochemical constituent revealed the presence of bioactive compounds such as flavonoid, alkaloid, saponin, steroid, triterpenoid, and tannin in different extracts of Tradescantia spathacea Sw. leaf. The methanolic leaf extract showed the best total phenolic and flavonoid content values of 83.35±0.00 mgGAE/g and 33.79±0.13 mg/g, respectively. Methanolic extracts also showed potent antioxidant activity in the DPPH assay with IC50 values of 80,835 µg/mL. The results suggest that Tradescantia spathacea Sw. could be an alternative source of natural antioxidant agents.
