The results showed that the flow of electrolytes from tanks outside the cell battery was able to increase battery capacity by increasing the number of spontaneous redox reactions during charging and discharging. The cycle time and battery capacity increase at the beginning of the filling-emptying cycle but have a downward trend with the increasing number of cycles.

The POE2WE model has been described as feasible and effective for use in the previous description. The POE2WE model is also equipped with a Model Book making it easier for other educators to apply the model (Nana, 2019a; Nana, 2019b). At the beginning of the 2020 decade, besides continuing to prepare students to live life in the 21st century and the era of the industrial revolution 4.0, there are other challenges that need to be faced in the education sector, namely the Cocid-19 Pandemic. This has made the learning system in Indonesia almost entirely turned to online learning. Online learning can be done synchronously and asynchronously. Synchronous online learning means that educators and students interact in the learning process at the same time in different places.Abstrak: Tujuan penelitian ini adalah : (1) Pengembangan yang menghasilkan bahan ajar berupa modul digital fisika berbasis Model POE2WE untuk mata kuliah Fisika Sekolah di masa New Normal.

This study was conducted by giving mice mangosteen peel extract with 5 different doses from those given 40 minutes of radiation exposure with a total dose of 268 μSv for 14 days, then the SGPT (serum glutamic pyruvic transaminase) levels were measured and cell damage figures from histopathological preparations. The results showed that before being given mangosteen peel extract, total damage to hepatocyte cells was 47.34%. After being given mangosteen peel extract, total damage to hepatocyte cells was 23.42%. Meanwhile, the SGPT level decreased to 77.7 U/L from the initial level of 128.67 U/L.
