Abstract

Abstract— This research aims to determine the corrosion rate of different types of nails by immersing them in water of the same quality. The method used is weight loss method. Each nail was immersed in water for 1–7 days and then weighed every day. The highest corrosion rate was obtained for steel nails with an average corrosion rate of 0.09 mmpy and the lowest corrosion rate was obtained for wall nails with an average corrosion rate of 0.02 mmpy. The largest difference in nail weight after soaking was for the umbrella nail at 0.48 grams, while the smallest difference in nail weight was for the wall nail at 0.11 grams.

Abstract

Reactive Oxygen Species (ROS) are a group of free radicals that play a major role in causing oxidative stress, which can trigger the development of degenerative diseases such as cancer. Sengkubak (Pycnarrhena cauliflora (Miers) Diels) contains antioxidant that may help protect the body from free radical exposure. This study aims to identify the metabolite compounds present in Sengkubak leaves through GC-MS analysis and to evaluate their anticancer potential of its major metabolites through in silico molecular docking analysis. The leaf simplicia was extracted using the maceration method with ethanol as the solvent. The analyses performed included GC-MS analysis and molecular docking analysis of the major compounds identified by GC-MS to evaluate their anticancer potential. GC-MS analysis identified a total of 84 compounds, with the five major ones being Phytol, Farnesol isomer a, L-Gala-L-ido-octose, E-11-HexadecenoicAacid ethyl ester, and Pentadecanoic acid ethyl ester. Furthermore, molecular docking analysis of the five major compounds demonstrated potential anticancer activity against breast cancer targets.

Abstract

Kampanye media sosial telah dilakukan untuk meningkatkan kesadaran generasi muda tentang pentingnya kendaraan listrik, sebuah solusi mobilitas berkelanjutan yang semakin relevan dalam upaya mengatasi polusi udara dan perubahan iklim. Kampanye ini melibatkan produksi dan distribusi video informatif melalui Instagram, yang mencakup lima poin utama: polusi udara, dampak kendaraan konvensional, konversi kendaraan BBM ke listrik, kelebihan kendaraan listrik terhadap lingkungan, dan perkembangan teknologi kendaraan listrik. Hasil kampanye menunjukkan video ditonton sebanyak 39.100 kali, memperoleh 440 likes, dan 52 komentar, dengan lebih dari 90% komentar berasal dari generasi muda. Respons positif ini menegaskan bahwa kampanye berhasil mencapai dan melibatkan audiens yang ditargetkan. Keberhasilan ini menunjukkan bahwa media sosial adalah alat yang efektif untuk edukasi dan promosi perubahan positif di kalangan generasi muda, mendukung adopsi kendaraan listrik dan transisi menuju mobilitas berkelanjutan.
