Abstract

Students' low chemical literacy and scientific attitudes in understanding chemical concepts, particularly in green chemistry, pose significant challenges in chemistry education today. Traditional learning models are often less effective in fostering 21st-century skills, such as critical thinking and problem-solving, which are essential for a more relevant and applicable chemistry education. This study aims to evaluate the impact of a STEM integrated with Problem-Based Learning (PBL) model on students' chemical literacy and scientific attitudes in green chemistry. Employing a quasi-experimental design, the study involved two experimental classes and two control classes. Each group participated in pretests and posttests to assess their chemical literacy and scientific attitudes. The analysis revealed that the PBL-STEM model significantly enhanced students' chemical literacy (N-Gain = 0.54) and scientific attitudes (N-Gain = 0.46) compared to traditional learning methods. Although the improvement in scientific attitudes was more pronounced, the increase in chemical literacy was relatively lower, indicating the necessity for adjustments in instructional approaches to deepen students' understanding of chemical concepts. The integration of green chemistry principles within the PBL-STEM model effectively connected chemistry education with global environmental challenges while also fostering 21st-century skills such as critical thinking and problem-solving. This study concludes that the PBL-STEM model presents a promising alternative for enhancing the quality of chemistry education and preparing students to navigate the complexities of an ever-evolving world.

Abstract

Mother Mother-to-child transmission (MTCT) is the primary route of HIV infection in children under 14 years. Despite the expansion of prevention of mother-to-child transmission (PMTCT) programs and increased antiretroviral therapy (ART) coverage, 17,000 children aged 0–14 years were living with HIV in Indonesia in 2023. This retrospective study analyzed infants born to HIV-positive mothers between January 2018 and December 2022, including only those with HIV polymerase chain reaction (PCR) test results. Of 86 infants, 21 (24.4%) tested positive for HIV, while 65 (75.6%) tested negative. Among those with positive results, 76.2% had an APGAR score <7, 90.5% were term, and 85.7% had a birth weight of ≥2500 grams. All infants received ART prophylaxis, and 91.9% were formula-fed. Infants whose mothers did not receive ART before birth or during labor had a 15-fold higher risk of HIV infection. Additionally, discontinuation of ART prophylaxis before six weeks of age increased the risk fourfold. These findings highlight the importance of early detection of HIV in pregnant women, optimising ART adherence during pregnancy, and providing ART prophylaxis to infants to reduce HIV transmission. Strengthening prevention of mother-to-child transmission (PMTCT) programmes is needed to reduce infant HIV cases in high-prevalence areas such as Papua.

Abstract

Pineapple (Ananas comosus L. Merr) contains various bioactive compounds, including the enzyme bromelain. Pineapple pith was chosen as a sample because it is still underutilized. This study aims to isolate secondary metabolite compounds from n-hexane extract of pineapple bark and test its antimicrobial activity. Maceration was carried out using n-hexane solvent, then the extract was separated by gravity column chromatography, resulting in four fractions. Separation of pure compounds using thin layer chromatography (KLT) with n-hexane:ethyl acetate (4:1) eluent. The second fraction produced a white crystalline compound (Ac-EH) with a melting point of 128-130°C. Characterization with UV-Vis showed absorption at λmax 268 nm and 206 nm, while FTIR identified the functional groups C-O (1047 cm-¹), CH₃ (1379 cm-¹), CH₂ (1465 cm-¹), C-H aliphatic (2939 cm-¹), and OH (3309 cm-¹). Phytochemical tests showed that Ac-EH belongs to the terpenoid group. Antimicrobial activity tests against Staphylococcus aureus, Staphylococcus epidermidis, and Candida albicans were carried out by diffusion method at concentrations of 20%, 30%, and 40%. The results showed that the n-hexane and Ac-EH extracts were active in inhibiting bacterial growth but not against fungi. The n-hexane extract inhibited S. aureus by 9.1 mm, 9.5 mm, and 9.8 mm and S. epidermidis by 8.1 mm, 8.4 mm, and 8.7 mm. The Ac-EH compound inhibited S. aureus by 8.5 mm, 8.9 mm, and 9.4 mm and S. epidermidis by 8.3 mm, 8.7 mm, and 9.1 mm.
