Cross-country military sports are sports that are contested in the military environment asan effort to foster the physical abilities of the Navy's soldiers. The doctrine in the Indonesian Navyforcefully demands every soldier to never give up in every task that is carried out so that in militarysporting events the soldier will spend all of his abilities. In the process of cross-country competitionwith heavy physical activity causing many soldiers who experience heat exhaust (pre heat strokeconditions) continue to force themselves to compete and will continue to become a heat stroke.This is compounded by the distance traveled so that the medical team had difficulty reaching thesoldiers who experienced the incident. Internet of things (IoT) is the idea that all objects in the realworld can communicate with each other as part of an integrated system using the internet networkas a link.By using the IoT platform it is possible to monitor an object continuously and provideanalysis directly without being limited by distance and time. Based on the description above, it isnecessary to design and build an early detection system for the heat stroke of TNI AL soldiers incross-country military sport activities based on IoT (Internet of Thing). This system can help detectpositions and soldiers who will experience heat stroke so that medical treatment can be given earlyto prevent heat stroke.Keywords: Monitoring, Heat Stroke, Cross Country, IoT.

Hasan Basri-382 Indonesian warhip (KRI) use MTU 16 V 4000 M 90 diesel engine with common rail technologythat uses a High Pressure Fuel Pump. The pump has a vital function because it provides fuel up to a pressureof 1400 bars on the common rail. The problem is that there is pump compilation or damage (leakage), then thefuel pressure at the High Pressure Pump input drops and risks the output pressure of the fuel High PressurePump towards the common rail, where the pressure drops dramatically, so that the fuel pressure is below 4 baror fuel pressure inside the common rail below 700 bar Engine Control Unit (ECU) accepts the engine to stop theengine. The price of the pump is too expensive. In addition, this pump cannot be repaired or in other words itmust be replaced by the new one. Based on the pump for life, it must be replaced every 4500 hours or in onceW5 maintenanc period. But this lifetime schedule has never been approved. Therefore, it is expected to causedamage to the pump so prevention efforts can be made. In addition, the author has also used the SWOTmethod to find the best strategy in finding solutions to the problems of this High Pressure Pump. And of course,these strategies are used for advice at the end of this settlement.Keywords: Common Rail, Damage, High Pressure Pump, Parchim Class, and SWOT Method
