Abstract

Invasi Normandia, juga dikenal sebagai Operasi Overlord, merupakan salah satu operasi militer terbesar dan paling penting selama Perang Dunia II. Keberhasilan operasi ini sangat bergantung pada peran strategis angkatan laut Sekutu, yang mencakup Amerika Serikat, Inggris, dan Kanada. Strategi angkatan laut ini melibatkan perencanaan dan persiapan yang cermat, termasuk operasi penipuan seperti Operasi Fortitude yang berhasil mengalihkan perhatian Jerman dari lokasi pendaratan yang sebenarnya. Pada hari-H, lebih dari 6.000 kapal dikerahkan untuk mendukung pendaratan di lima pantai utama di Normandia, dengan tugas utama memberikan tembakan pendukung untuk menghancurkan pertahanan pantai Jerman, melindungi armada transportasi, dan memastikan kelancaran logistik. Penguasaan laut yang dimiliki Sekutu memungkinkan mereka untuk mengirim pasukan dan persenjataan dalam jumlah besar, yang berperan krusial dalam mempertahankan kepala jembatan dan memperluas operasi militer di Eropa Barat. Strategi angkatan laut yang efektif juga berhasil mengurangi kemampuan Jerman untuk memperkuat pasukan mereka di Normandia, yang pada akhirnya berkontribusi besar pada kemenangan Sekutu. Kesimpulannya, superioritas maritim dan koordinasi yang tepat antara angkatan laut dan darat adalah faktor penentu dalam keberhasilan Invasi Normandia, yang membuka jalan bagi pembebasan Eropa Barat dari pendudukan Nazi. Studi ini menyoroti pentingnya strategi angkatan laut dalam operasi militer skala besar dan dampaknya terhadap hasil perang.

Abstract

This research examines the implementation of the Revolution in Military Affairs (RMA) concept in the Russian-Ukrainian War, focusing on its impact on military strategies and operational tactics. RMA involves transformative changes in military technology, doctrine, and organization, reshaping modern warfare. In this conflict, elements such as drone technology, cyber warfare, and network-based weapon systems have been pivotal. Using a descriptive analysis method, the study collected data from military reports, journal articles, and news sources to identify how RMA was applied by both sides and evaluate the influence of modern technology on the conflict's outcomes. The analysis focused on Unmanned Aerial Vehicles (UAVs), electronic warfare systems, and network-based defenses, which intensified the complexity and pace of operations. The findings reveal that both Russia and Ukraine adopted RMA elements, albeit with varying capabilities and effectiveness.

Abstract

Antioxidants are compounds that can delay, slow down, or inhibit the oxidation reaction of food or medicine. Antioxidants include electron-donor compounds that work by donating an electron to compounds that are free radicals so that radical activity is inhibited. One of the plants that can be used as a source of natural antioxidants is salam leaf (Syzygium polyanthum (Wight.) Walp). Salam leaves contain secondary metabolite compounds, including alkaloids, tannins, saponins, steroids, triterpenoids, and flavonoids, which act as antioxidants. The study aimed to determine whether the methanol extract of salam leaves (Syzygium polyanthum (Wight.) Walp.), which grows in Gampong Bunot, Pidie Jaya, contains secondary metabolites and has activity as an antioxidant. This research was conducted experimentally, where the sample used was salam leaves. The stages of this research included the processing of plant materials, preparation of methanol extract of salam leaves, characterization examination, phytochemical screening, and antioxidant activity test of methanol extract of salam leaves using the DPPH method. Salam leaf extract was prepared by maceration method using methanol solvent obtained and concentrated with a rotary evaporator, then the phytochemical screening test and the antioxidant activity test of the methanol extract of salam leaves were carried out using the DPPH method (1,1 diphenyl-2-picrylhidrazil) at a wavelength of 516 nm and vitamin C as a comparison. Based on the results of the phytochemical screening test, there were differences in secondary metabolites in the methanol extract of salam leaves grown in Gampong Bunot, Pidie Jaya, including alkaloids, flavonoids, saponins, tannins, steroids, and glycosides. The results of the antioxidant activity test of the methanol extract of salam leaves obtained the IC value50 of 25.68 µg/ml and the IC value50 Vitamin C of 4.537 µg/ml in the second category is very strong.

Abstract

Cyberbullying or online bullying has become an alarming global phenomenon, especially in the current digital era. This study discusses and compares the policies and approaches implemented by Indonesia and South Korea in handling cyberbullying cases. The comparative descriptive approach used in this research collects data from various secondary sources, including scientific literature, research reports, and legal and policy documents. Policies for handling cyberbullying are regulated through the Information and Electronic Transactions Law as well as several additional regulations, although they still face challenges in effective and consistent implementation. Meanwhile, South Korea relies on several key legal products and an inclusive approach, although its regulatory implementation also faces challenges. Both countries have their own complexities in dealing with cyberbullying, which are influenced by social, cultural and technological factors. The results of this research emphasize the importance of inter-agency coordination, improvements in legal definitions, and increased public awareness as keys to increasing victim protection and reducing future cyberbullying incidents.

Abstract

The Normandy invasion, also known as Operation Overlord, was one of the most monumental events in the history of World War II. On June 6, 1944, nearly three million Allied troops crossed the English Channel from England into France occupied by Nazi Germany. The invasion of Normandy opened the way to the liberation of Europe and finally ended World War II. Naval strategy was crucial in this operation to support the landing of troops on the beaches of Normandy. In the context of naval strategy, the Normandy invasion involved coordination between the navy, army, and air force. The writing methodology uses a descriptive method by analyzing the facts that occurred during the 1944 Normandy battle and is supported by literature studies, literature and various scientific journals.
