The function and role of the Strategic Sealift Vessel (SSV) ship type is very important. Modifications andchanges to improve the value of efficiency will be very necessary. This efficiency value is closely related to thevalue of Ship Resistance , where if the Resistance value goes down, the value of the ship's efficiency will rise.The increase in efficiency is then expected to reduce fuel consumption and increase speed. In several studies,ways have been improved to improve the condition, one of them is by adding a Dimple to the Surface Area ofthe ship, this modification will reduce the friction Resistance that the ship will receive by reducing the WettedSurface Area that the fluid will pass at certain speeds and conditions. . This modification will be applied to theship's Bulbous Bow section. In this way it is expected to improve the value of the Resistance produced by theBulbous Bow installed in the ship, without having to carry out significant changes or modifications and changethe shipbuilding of the existing Linesplane. Furthermore, the analysis is carried out by modeling using 2D and3D CAD Software and Model Experiments using CFD Applications. After carrying out the entire process ofRunning with the CFD Software to determine the value of the Ship Resistance . The final conclusion is in theform a reduction the value of vessel Total Resistance the Running Bow section of 31.53% in the 4th variationsand Fn used is 0,341.Keywords: Boulbous Bow, CFD, Dimple, Reduction, Resistance

Image processing shooter-based Information System is very useful for STTAL, which has a visionto become a center for the development of defense science and technology in the field of military,maritime and reliable seas at the regional level in realizing the independence of the main weaponssystem.STTAL has the mission of organizing higher education programs to produce human resourceswith Indonesian character and personality, based on science and technology that are of high quality andrelevant to the defense needs of the military, maritime and marine departures. In carrying out its duties asan educational institution, STTAL also carries out its obligations as the Indonesian National Army. So withthat STTAL often hold short barrel or pistol shooting exercises. In a series of short barrel or pistolshooting activities, each process of recording values is still carried out visually, that is by looking directlyat the target and counting manually, so that it takes a lot of members of the shooting committee and takesa long time in recording values. We design a application of image processing information system basedshots which can be used in shooting exercises to facilitate all members in carrying out shooting exercisesat STTAL. In this application the shooter can see firsthand the value of the shot obtained so that it canconcentrate fully in carrying out a shooting exercise. In this application also makes it easy for the head ofthe shooting committee to make a report to the commander quickly and accurately, for the commander tosee first hand the results of the shooting practice and it's easy to take a decision on shooting practice.Keywords: Value Marker, Shooting, Image Process.
