Abstract

Breast cancer is the most prevalent cancer among women and is the leading cause of cancer-related mortality worldwide. This underlines the importance of preventive strategies to reduce the risk. Harnessing natural products like tea could be an alternative preventive strategy. In this study, the chemopreventive potential of roselle flower tea (Hibiscus sabdariffa L.) enriched with cinnamon oil (Cinnamomum burmannii) and lemongrass (Cymbopogon citratus) was evaluated. The tea was formulated using a stirred boiler tank and tested for its cytotoxicity against T47D cells using the MTT method. The cytotoxicity test showed that with the addition of cinnamon oil and lemongrass, roselle tea had more significant cytotoxic activity against T47D cancer cells than pristine roselle tea. Adding 5 g of cinnamon and lemongrass oil vapor for 15 seconds into the tea showed the highest cytotoxicity, with an IC50 of 730 μg/mL. This value is almost three times higher than without adding cinnamon oil and lemongrass. In conclusion, adding cinnamon oil and lemongrass to the roselle tea formulation can increase cytotoxic activity against T47D cancer cells, indicating its potential as a natural anti-cancer agent.Keywords: Chemopreventive, Cinnamon, Lemongrass, Roselle Tea, T47D Cells.

Abstract

Pada saat dilakukan inspeksi rutin pada maintenance C-check pesawat Airbus A321-211, terindikasi adanya kebocoran bahan bakar pada tangki bahan bakar tengah (center fuel tank). Langkah pertama yang dilakukan adalah identifikasi kemungkinan penyebab masalah kebocoran tersebut berdasarkan TSM 28-13-00-810-801-A. Hal ini dilakukan untuk mengetahui lebih detail letak kebocoran. Kerusakan pada sealant dicurigai sebagai penyebab utama. Untuk memastikan hal tersebut, dilakukan pembukaan akses tangki bahan bakar tengah bagian kanan dan inspeksi pada struktur dalam tangki sesuai dengan SRM 51-76-12. Metode penelitian yang digunakan adalah deskriptif, yaitu melibatkan inspeksi visual dan pengujian sealant setelah perbaikan. . Hasil penelitian menunjukkan bahwa pemeriksaan struktur dan sealant adalah hal yang harus dilakukan untuk menemukan penyebab kebocoran fuel. Jika struktur dalam keadaan baik, maka sealant yang rusak akan diganti. Setelah melakukan perbaikan pada sealant center fuel wing, seluruh bahan bakar pada tangki sayap kemudian dialihkan ke tangki tengah untuk memastikan sealant dalam keadaan kering dan baik sehingga kebocoran tidak terjadi. Tangki bahan bakar tengah merupakan bagian penting untuk menampung bahan bakar pesawat. Kebocoran pada tangki ini dapat mengakibatkan berkurangnya jumlah bahan bakar yang tersedia.

Abstract

The Ministry of Education, Culture, Research, and Technology fostered the Merdeka Curriculum program as a significant endeavor to recuperate from the academic situation after the COVID-19 outbreak. The Merdeka Curriculum has shown better results two years after the pandemic than in the previous academic years. It indicates that learning will be more significant if students independently find ideas through the logical cycle since this can create and bring about scientific attitudes. This research aims to analyze the validity of the guided inquiry-based teaching module on additives to improve students' scientific attitudes. This is an R&D study adopting the 4D model and restricted to the development stage. Questionnaires were used as the instrument for the data collection. The validation included media and content validity, carried out by respectively 1 lecturer as a media specialist and 1 lecturer as a content specialist. The validation results revealed that the developed teaching module obtained 0.95 with very valid criteria from the media specialist and 0.96 with very valid criteria from the content specialist. In sum, the developed teaching module is valid for use in the learning process.

Abstract

Global demand for fossil energy continues to increase, affecting both the environment and energy availability. This study aims to describe energy crisis and its impacts, the adoption of renewable energy (RE), and the educational challenges in addressing these problems in Indonesia.  The Systematic Literature Review method was conducted using the Harzing’s Publish or Perish application for Scopus and Google Scholar indexed articles with the keywords “energy crisis,” “renewable energy,” “energy education Indonesia,” and “impact of fossil energy”, covering publications from 2017 to March 2025. A total of 116 articles met the eligibility criteria. The results indicate that the environmental impacts include increases in CO2 emissions driven by urbanization, industrialization, and transportation. Globally, RE adoption remains at only 1%. The use of renewable energy in Indonesia is relatively low, at 11.31% of the available energy supply. Indonesia’s educational strategies include establishing specialized schools for the development of RE, curriculum support, and implementing project-based learning. These strategies must be replicated and further developed by other institutions. Through these efforts, Indonesia is expected to become more aware of the limitations and impacts of fossil energy and better able to utilize the availability of RE.
