One of the activities in the two-wheeled automotive industry is the process of sending components or parts from suppliers to motorcycle assembly plants. Delivery of parts using the fleet of each supplier. Along with the increase in market demand, the demand for components to suppliers is also increasing. This has an impact on increasing the number and frequency of fleets entering the factory area, besides that there is also an increase in transportation costs. This study aims to make the efficiency of the number, frequency and cost of fleet transportation by using the Milkrun approach and VRP (Vehicle Routing Problem). To get optimal results, the PSO (Particle Swarm Optimization) and GA (Genetic Algorithm) methods are used by utilizing the Matlab 2022 software. This research involved 40 suppliers, Logistic Partners and motorcycle assembly factories. The results of this study showed better results, namely before the research the number of fleets was 40 units and the frequency of 40 shipments with a total shipping cost of IDR 2,769,330, while after the research with the PSO optimization method the fleet number was 5 units and the frequency of 8 shipments with a total shipping cost of IDR 2,679,113. For GA optimization, the number of fleets is 4 units and the frequency is 8 times of delivery with a total shipping cost of IDR 2,000,058.

Abstract

- The Naval Base is one of the Main Commands for the development and operation of the Indonesian Navy. In order to be able to support all the tasks carried out by the Indonesian Navy, the base has responsibility for the implementation of the combat readiness and alertness of the elements of the Indonesian Warship (KRI) under it, which is part of the function of the base. Fire is a barrier factor for the base in its efforts to maintain the readiness and combat readiness of the KRI elements. PMK Lantamal Surabaya is a fire hazard management unit that has a working area at the Navy base. Currently there is no tool that is specifically provided to call firefighters in the area of the Naval base, the tool used to call firefighters today still utilizes a Central Telephone whose function is not only for fire emergencies but also for various uses, thus making firefighters slow to respond. In this study the authors tried to design a tool in the form of a Fire Extinguisher Calling Tool. With this fire extinguisher calling device, it can help firefighters respond more quickly to fire emergencies. This study uses the Quality Function Deployment (QFD) method. The QFD method is used to translate consumer needs and desires into product design characteristics. In this study, there were 2 (two) sources of Voice of Customer (VoC) data input, namely the implementing consumers were firefighters and consumer users were all Indonesian Navy soldiers. From the results of identifying consumer needs, solving existing contradictions is carried out by drafting and selecting concepts to obtain optimal results and produce several alternative product designs according to the standards desired by consumers.

Abstract

The territory of the Unitary State of the Republic of Indonesia has sea waters that are wider than the land area, besides that the sea waters area has a wealth of diverse natural resources both in the fields of hydrography and oceanography. However, if faced with other threats originating from below the surface of the water, such as the Autonomous Underwater Vehicle (AUV), ships on the water will find it difficult to detect because the AUV has secrecy and intrusion properties that are difficult for opponents to detect. The Hugin 1000 Autonomous Underwater Vehicle has a navigation system and survey equipment system with acoustic wave transmission which is influenced by the physical properties of the water medium such as temperature and salinity. Every change in the physical properties of water is largely determined by the depth of the water column and its geographic location. The concept of winning a war at sea is that we are able to master the underwater battlefield to provide an advantage that can be used to defeat the opposing forces. The concept of underwater warfare is more complicated than warfare over water, because not only do we have to gain technological superiority from our opponents, but also knowledge and sufficient information about the characteristics of our own combat/operations mandala such as the completeness of hydrographic and oceanographic data. The development and advancement of technology in the field of underwater detection is so rapid that understanding the information dynamics of hydro-oceanographic parameters is one of the keys in determining the superiority of the battle. With good data in the form of hydrographic and oceanographic data, it will be easier to determine strategies in battle. The concept of underwater warfare is more complicated than warfare over water, because not only do we have to gain the advantage of the opponent's technology, but also knowledge and sufficient information about the characteristics of the combat/operational mandala itself, such as the completeness of hydro-oceanographic data.

Abstract

- Bulk-cash smuggling is the act of hiding a currency or monetary instrument with the intent to circumvent reporting requirements, through the transportation, transfer, or attempted transportation or transfer of currency or monetary instruments from one country to another. According to Law Number 8 of 2010 concerning the Prevention and Eradication of Money Laundering, it is stated that money smuggling is one part of money laundering crimes. In its development, cash smuggling, which was originally a stage of money laundering activities, has now become a form of transnational crime. Criminals generally use transportation media such as commercial and private aircraft, ships and transport vehicles and pedestrians to cross borders between countries. This research uses a qualitative method approach with SWOT analysis tools. Data collection comes from literature studies in the form of books, journals and other sources of information. The results showed that to overcome the problem of money smuggling can be done through efforts: increasing the presence of defense equipment of each stakeholder in border areas, increasing the degree of operation of each stakeholder independently and integrated to prevent money smuggling crimes and increasing the ability and professionalism of security forces in facing the threat of money smuggling.

Abstract

An economic embargo imposed by the US, Netherlands and Britain on Japan has forced the country to seek natural resources (petroleum) in Southeast Asia to sustain its war needs. This reason then motivated Japan to attack and control natural resources on the island of Sumatra and Java. The Japanese invasion of Palembang for control of the Allied oil refinery at Plaju and the battle of the Java Sea were evidence of Japan's ambition to control Indonesia's natural wealth. This research uses a qualitative method approach with a type of literature study research. Data collection comes from literature studies in the form of books, journals and other sources of information. The benefit that can be taken from this battle analysis is that natural resources and energy are attractions that can trigger
