Abstract The Malacca Strait is a very strategic world trade route and the potential for environmental pollution is also very large, especially pollution from ship and people activities. This study aims to perform numerical simulations to determine the movement of marine debris particles around the waters of Rupat Island, Malacca Strait. The modelling was carried out from June to December 2020 using a modelling application with the basic principles of mesh discretization and the Lagrangian method. The results showed maximum current velocity during the simulation around the distribution area of debris is a maximum of 0.92 m/s. Marine debris around the waters of Rupat Island, the Malacca Strait has the potential to be stranded on the mainland of Rupat Island, mainland Riau, Bengkalis Island and also mainland Malaysia.

Abstract This paper will explain the consequences of Indonesia's geopolitical location, namely in the Malacca Strait as an international trade route. The Malacca Strait is a crossing route for foreign ships to distribute goods to various regions. However, the strategic channel not only attracts sympathy from international entrepreneurs but also attracts these criminals and hijackers to obtain economic results from this activity. The Malacca Strait strategically makes pirates and pirates criminalize passing ships. On the other hand, the consequences of state legal matters are maintaining security and safety, and the comfort of crossings in the Malacca Strait. With a number of problems, both defense, governance and management infrastructure that cannot be seen in a fixed manner. In addition, its position borders on three countries, namely Indonesia, Malaysia and Singapore. With a qualitative descriptive analysis method, this paper explains the need for bilateral, trilateral and regional multi-level diplomacy approaches to solve problems. And the purpose of this article is that piracy occurred in the Straits of Malacca because of its strategic geopolitical structure and weak Indonesian defense. So, collaboration is needed, coordination through diplomacy and military projections as an effort to safeguard the sea area, sea control and military defense articulation. Thus, the authors hope that this article can add knowledge to the study of international relations, especially in marine studies. Keywords: Geopolitics, Maritime State, Malacca Strait, Piracy, Multilevel Diplomacy   Abstrak Paper ini akan menjelaskan konsekuensi dari lokasi geopolitik Indonesia, yaitu di Selat Malaka sebagai rute perdagangan internasional. Selat Malaka adalah rute penyeberangan bagi kapal-kapal asing untuk mendistribusikan barang ke berbagai daerah. Namun, saluran strategis tidak hanya menarik simpati dari pengusaha internasional tetapi juga menarik para pelaku kejahatan dan pembajak ini untuk mendapatkan hasil ekonomi dari kegiatan ini. Selat Malaka yang strategis membuat perompak dan pembajak mengkriminalkan kapal yang lewat. Sisi lain, konsekuensi dari urusan hukum negara adalah menjaga keamanan dan keselamatan, dan kenyamanan penyeberangan di Selat Malaka. Dengan sejumlah masalah baik pertahanan, tata kelola, infrastruktur manajemen yang tidak bisa dilihat secara secara terpisa. Selain itu  posisinya berbatasan dengan tiga negara yaitu Indonesia, Malaysia dan Singapura. Dengan metode analisis deskriptif kualitatif, makalah ini menjelaskan perlunya pendekatan diplomasi multi-level bilateral, trilateral dan regional untuk menyelesaikan masalah. Dan tujuan dari artikel ini bahwa pembajakan terjadi di Selat Malaka karena struktur geopolitik yang strategis dan pertahanan Indonesia yang lemah. Jadi, diperlukan kolaborasi, koordinasi melalui diplomasi dan proyeksi militer sebagai upaya untuk menjaga wilayah laut, kontrol laut dan artikulasi pertahanan militer. Dengan demikian, penulis berharap bahwa artikel ini dapat menambah pengetahuan untuk studi hubungan internasional khususnya dalam studi kelautan.

The Strait of Malacca is the busiest in the world. It happens because the Malacca Strait is one of the essential keys in energy trading. It started from being the target of pirates and armed robbery to the target of foreign intervention in the Malacca Strait. Feeling that its sovereignty was threatened, Indonesia did several things to maintain the sovereignty of the Malacca Strait as part of Indonesian territory. It was starting from the refusal to cooperate with foreigners to cooperate with the littoral state. This paper will explain the importance of the Malacca Straits in world trade and why Indonesia's sovereignty is threatened due to foreign activities in the Malacca Strait. This paper is based on Indonesia's geostrategy and National Resilience which is part of Indonesia's geostrategy itself.

One of the goals of the world trade organization is to ensure free and fair trade around the world. Bound tariff rate and most-favored-nation treatment are two basic principles in WTO law, which should be applied and observed among WTO members. The implementation of “trump tariffs” has resulted in a “trade war between China and other countries”, which undoubtedly constitutes a violation of WTO principles, including violation of bound tariff rates and most-favored-nation treatment. At present, the United States is still one of the major setters of the world’s rules, and its every measure has an impact on the whole world. In addition to opposition from around the world, the trump administration’s move to impose tariffs has been criticized by most local economists and lawyers. To achieve fair and free trade, the trump administration should end the implementation of trump tariffs and fulfill its obligations in global multilateral trade and the WTO.

This paper examines differences between Northwest Europe and Eastern North America with respect to port commercial activities, port policy, port hinterland access and competition, port governance, and port security. While the volume of traffic on the transatlantic trade route has grown, its share of world trade with Europe has declined slightly. The authors explore the relevant contextual issues the ports on the trade route have experienced in the last decade, and using the Baltazar and Brooks (2001) Environment-Strategy-Structure framework, examine the structure and strategies followed by ports as they seek to deal with the changing environment (context) on all routes, not just the transatlantic.

This article describes the belt sets decorated by metal plaques with nodular rims, which we term Redikar sets after the place where they were fi rst found in a hoard. They are believed to mark the Magyar migration to Pannonia. We discuss the question of when and how such and similar belts got to the Volga Finns of the Lower Oka. The mapping of parallels suggests that their principal distribution area is the Kama basin and western Ural, i.e. places formerly inhabited by Ugrians. Stylistically, the decoration of such belts resembles that of Iranian toreutics and of the cast ritual items from the western Ural (Perm) and eastern Ural. Because trade and manufacture centers with jewelers’ workshops associated with silver mines existed in the Kama basin, this might have been the area from where silver belts of the Redikar type were brought to the Volga basin. The chronology of the fi nds is analyzed in detail, and the conclusion is made that they date to the fi rst half of the 10th century. On the Lower Oka, in the western Ural, and in the Kama basin, the Redikar belts are found in burials of the military elite members. Theу were supplied to the Mordvins along the Volga-Kama trade route, spanning territories from the Ural to Scandinavia. Their presence in cemeteries on the Tsna River suggests that Volga Finns were involved in the formation of early states at the turn of the fi rst and second millennia.

The Malacca Strait, which has always been the world's most strategic trade route, has become the most frequently traversed by international ships. The potential for environmental pollution in the Malacca Strait is also enormous, especially pollution from ship waste in the form of liquid waste (water ballasts and hazardous toxic materials, or B3 liquid waste) and garbage from disposal during illegal ship washing. Bintan Island, which located close to the Malacca Strait, is one of the islands affected by foreign ship dumping, which avoids sanctions throughout Indonesia, such as Malaysia and Singapore, which require every incoming vessel to be clean of waste. Regulations made by the Singapore government regarding the inspection of the ships of each ship resulted in the act of washing boats in the Malacca Strait. Cleaning and washing tanks and vessels in inappropriate areas can result in environmental pollution caused by wastewater in the form of water, oil, and plastic waste that is very damaging to the environment. The establishment of an exclusive zone for ships carrying out ship cleaning activities as well as anchored anchor locations can reduce environmental damage in the Malacca Strait. This study uses a qualitative method using an ecological approach to see how ecological problems caused by ships cause cross-border issues that threaten ecosystems in the Malacca Strait, specifically the Bintan Islands conservation area. The data used in the form of qualitative data collected through document studies, interviews, document analysis, focused discussions, and observations made.

The Malacca Strait, which has always been the most strategic world trade route. The majority of foreign vessels crossing the Malacca Strait transit at the Port of Singapore. The potential of environmental pollution in the Malacca Strait area is also very large, especially the pollution from vessel waste resulting from the operational activities of vessels in the form of liquid waste and garbage dumped in vain and the washing of vessels illegally. The operational activities of foreign ships in violation of international treaties and Indonesian law often occur in Indonesian coastal areas. Indonesian waters were victims of foreign vessels who carried out illegal activities in order to reduce operational costs and avoid sanctions from the port authorities and the Singapore's sincerity which required that every vessel to be anchored in Singapore's port was clean from waste. Regulations made by the Singapore Government encourage illegal ship laundering and waste disposal in the Straits of Malacca. The supervision of severe penalties against each vessel that crosses and violates the rules, and the establishment of a special zone of vessel cleaning in the Straits of Malacca can reduce environmental damage. This research uses qualitative methods using rational choice and institutional approach in environmental view to see how environmental problems caused by vessel waste occurred and cause cross border problems threatening ecosystem in the Straits of Malacca, especially the Indonesian water area. Data used in the form of qualitative data are collected through document studies, interviews, document analysis, focused discussions, and observations made.
