ABSTRACT The future threat to the world, including Indonesia, is natural disasters. The Navy as a means of state defense places natural disaster management as a form of military operation task other than war. Landing Ship Tank (LST) type warship is a defense system capable of delivering logistics on a large scale directly to disaster locations via beaching. The main problem is still finding delays and failures in logistics delivery caused by equipment damage with the biggest loss being the sinking of warships. The aim of the research is to minimize the occurrence of risk events by making a risk management design based on the ISO 31000 framework which focuses on warship operations. The method used by the House of Risk (HOR) is divided into two stages. HOR stage 1 focuses on ranking the Aggregate Risk Potential (ARP) value with the help of a Pareto diagram to determine the selected risk agent, which then requires treatment on a priority scale. The results of the HOR stage 1 are then entered into the HOR stage 2 to obtain the most effective preventive action. The results obtained, there are 8 risk agents that need to be handled. Furthermore, based on brainstorming with the Expert (the commander of the warship) obtained 12 mitigation actions that can be implemented immediately. Keywords: Risk Analysis, Landing Ship Tank, HOR. 1. INTRODUCTION Indonesia is a country that is located between 3 tectonic plate meeting paths, which results in frequent earthquakes. The movement of the three plates causes the islands of Indonesia to experience earthquake vibrations from time to time, especially in the area where the plates meet, namely the meeting of the Eurasian plate and the Australian plate along the islands of Sumatra, Java, Bali, Nusa Tenggara, and the meeting of the Australian and Pacific plates in the island region. Papuans. This is because Indonesia is on the path of earth's tectonic and volcanic activity. Both of these activities are natural processes of the planet Earth which is always moving (Arie Priambodo, 2009). Figure 1. Disaster Map in Indonesia The Navy as an element of power at sea is required to be able to carry out its duties through strength building that is focused on the power structure through the Integrated Fleet Weapon System. These components are Republic of Indonesia ships, marines, aircraft and bases (Putra, 2016). The Navy has warships delivering troops on a large scale, especially in amphibious operations, namely landing ship tank (LST) types. In carrying out its main tasks related to amphibious operations, this type of warship is under the Amphibious Ship Unit. LST has the advantage that it is able to dock at the low tide line farthest from the target beach, so that it can carry out landings at coastal locations. The current condition of the existing LST type warships is over 30 years old, namely the Frosch type LST, a former East German Navy ship made in 1977 and the Korean-made LST in 1980. Other problems are personnel limitations and the unpreparedness of the warship's technical condition which results in not achieving organizational goals. The use of alternative spare parts in overcoming the limitations of spare parts can cause disturbances and obstacles during operational implementation. The following are some of the risk events experienced by LST type warships that cause light to heavy losses. 2. consisting of principles, frameworks and processes. The risk management process is a series of risk management activities that deal with risks one by one and in groups according to the type of target affected. Thus, the risk management process is the core of the overall risk management (Kaho, 2018). The implementation of risk management in a company is very necessary, as the implementation guidelines have been set based on SN ISO 31000. 2.3 The Risk Management Process is based on the ISO 31000 standard consists of systematic application of procedures, policies, and several approaches in the application of communication and consultation, building context and assessing risk, treatment, monitoring, reviewing, recording and reporting to interested parties. The risk management process must be an integral part of management and decision making, and integrated into the structure, operations and processes of the organization. Therefore, there are many process models for implementing risk management in organizations, specifically designed for the needs of achieving various organizational goals that are in line with the internal and external context of the organization, where the risk management process is carried out. MATERIALS AND METHODS 2. 1 Risk Risk is defined as "the adverse impact on probability of several distinct sources of uncertainty". Risk is defined as the uncertainty caused by changes. Risk is a deviation from something expected (Joel Bessis, 2010). This uncertainty factor ultimately causes risk in an activity 2.2 The Risk Management Process Risk management Risk Management is defined as a directed and coordinated organizational activity, which is related to the risks that exist in the organization. Risk management has several components Figure 2.
