Abstract

The Gulf of Guinea, an area rich in natural beauty and natural resources such as oil, gas, and fisheries, faces serious threats from widespread maritime piracy activities. The region is an important economic center, but maritime insecurity threatens its economic stability and development. Numerous regional and international initiatives have been undertaken to enhance security in these waterways, such as the Nigerian government's "Deep Blue" project and collaboration with the Economic Community of West African States (ECOWAS). The UN Security Council has also passed a resolution to address this threat. Despite this, challenges remain significant due to the high number of attacks and significant economic impact. Addressing this issue requires continued cooperation between countries in the Gulf of Guinea region and the international community to ensure security and sustainable exploration in this region​.

Abstract

Fossil energies as un-renewable energies have been getting depletion. Therefore, the use of alternative energy should be raised. One of the alternative energies is solar energy. Solar energy does not pollute the environment and is categorized as a renewable energy which is free and plentiful.   In this research, the solar energy was used to heat water by operating granite absorber solar collectors. The water was flowed naturally from a higher tank and adjusted using a valve fitted at the outlet of the collector.  The volumetric rates of the water were 200, 250 and 300 cc/minutes. Two identical solar collectors with an overall dimension of 0,8 m x 1 m x 0,1 m were placed under the sun and faced to the North with an inclination angle of 15°. One collector contained 5 parallel pipes and the other comprised 7 parallel pipes.  Data obtained in this research are glass cover temperatures, an ambient temperature, absorber temperatures, inlet and outlet water temperatures, and water volumetric rates. The results show that the 7 parallel pipe collector products higher outlet water temperature and energy than the 5 parallel pipe collector. Consequently, in the process of energy removal/discharge, the heat stored in the 7 parallel pipe collector runs out quicker.

Abstract

The conflict between Hamas and Israel has created a complex asymmetric warfare environment, giving rise to elements of hybrid warfare involving both military and non-military tactics. Hybrid warfare is not a new idea. The focus is primarily on the ability to target distant objects and processes through unconventional military methods, especially for state and military functions. Hybrid warfare, known as an asymmetric approach, seeks to achieve major impact using simple methods, such as stopping an enemy's military operations or cutting off public political support. The operational environment of hybrid warfare consists of a series of interrelated areas of conflict, such as military, economic, social, information, diplomatic, trade, science, and technology. Since states involved in hybrid war do so by undertaking centralized actions in all areas of conflict subject to a single goal, it follows that the actions undertaken by states involved in hybrid war must also be centralized in all areas. Hybrid warfare requires both conventional and unconventional instruments of power and means of subversion. This research aims to analyze the elements of hybrid war in the context of an asymmetric war between Hamas and Israel in 2023.

Abstract

War is an event that can be avoided by most countries in the world. War may be the last alternative that must be taken if diplomacy do not reach an agreement. One of the categories of warfare that results is the asymmetric warfare pattern, which has become a trend in the form of warfare in the current era. Asymmetric warfare describes modern conflicts that exploit power inequalities between the parties involved. It involves tactics and strategies that are different from conventional warfare. The Southwest Papua region has become the center of international attention in recent years due to the increasingly worrying escalation of the terrorist conflict. To understand the escalation of terrorism in Southwest Papua, we need to consider the long history of ethnic and political conflict in the region. Terrorism in Southwest Papua is not only a threat to security, but also an asymmetric war with significant long-term implications due to dissatisfaction and feelings of marginalization that have existed for decades. This article also refers to data and case studies to provide a deeper understanding of terrorism in the Southwest Papua region and its relevance within the framework of asymmetric warfare. The research method in this writing uses a library study method which will be obtained from library sources such as books, websites, articles, journals, and so on. It is hoped that the results of this research will provide an understanding of the causes of terrorism in the Southwest Papua region as asymmetric warfare occurred in Indonesia.
