Panzer Anoa 6x6 is a combat vehicle on tires where the first generation of it is made by PT Pindad (Persero). It can mobility, protection and carrying capacity. The ramp door on the Anoa 6x6 APC armored vehicle is driven by a hydraulic system to support the mobility of personnel when exiting or entering the vehicle. The components of the hydraulic system driving the Panzer Anoa 6x6 APC ram door include batteries, power packs, solenoid valves, hydraulic hoses, and hydraulic cylinders. These problems include the ramp door often not functioning, the ramp door moving too slowly and often experiencing congestion when the ramp door is working. These constraints often occur because the pump in the hydraulic system is driven by an electric motor that gets its power source from the battery. The fluid is pressed and flowed through a hydraulic pipe, then the flow of the pressurized fluid is regulated by a solenoid valve to the hydraulic cylinder to move the ramp door. This study uses a pure experimental quantitative method with empirical calculations to obtain a tool with the desired specifications. To move the ramp door weighing 200 kg with a maximum opening angle of 100 degrees in 8 seconds, the heaviest load received by the cylinder is 23557.44 N, the working pressure that occurs in the cylinder is 87.49 bar, where the fluid discharge will flow to the pump. of 2164.77 liters/minute, with a pump power of 394570 Watt and to continue the rotation of the engine with a rotation of 2814.13 rpm (idle) to the hydraulic pump using a pulley mechanism with a ratio of 1: 0.15.

Combat technology in the military world has undergone a very rapid development in both close combat and long-range combat. Long-range combat is identical to a rocket weapon where the rocket works because of the presence of an igniter that serves to burn the propellant so that when the propellant burns it will produce pressure that will push the rocket hurtling towards a predetermined target. Igniter is very important in the launch of rockets where the filling of the igniter is black powder that has been difficult to obtain because of the difficult manufacturing process and risk of explosion. This research aims to design a tool that can produce black powder with a large enough capacity and good quality and reduce the risk of explosions to support the manufacture of igniters for rocket launches, especially those owned by Indonesian Army. This research used pure experimental quantitative method with empirical calculations to obtain tools with the desired specifications. The results obtained after the calculation are the volume of octagonal prism tubes 2942.5 cm3, the total volume of steel balls with two size variations is 979.5 cm3, the maximum lendutan that occurs on the shaft of the player is 0.108 mm, so it is said to be safe.

Abstract: Airless tires are the best innovation for military tactical vehicles in carrying out the Army's main tasks for military tactical even peace support operations and war military operations. However, in its development there are still imperfections in the results, its fabrications in the adhesion between polyurethane and natural rubber. Therefore, the researchers aimed to develop the adhesion between polyurethane and natural rubber. In this research, a quantitative experimental method was used, namely by varying the hardness of natural rubber and polyurethane to determine the right hardness for airless tires for maximum adhesion. The problem that occurs is that the adhesive glue with the tire tread is problematic, resulting in a tire tread condition without air being released. In carrying out the research, a function test was carried out with a planned weight of 4,500 Kg. Based on the results of the tests that carried out, the correct result was obtained, namely the elongation at break of the most appropriate type of polyurethane L100, which was 9.287 MPa. In order to achieve the goal, namely the appropriate level of elasticity between polyurethane and natural rubber so as to be able to glue the spokes and tire treads, in the end the wheel rotation will rotate according to the desired elasticity.

The era of the Industrial Revolution 4.0 military power became one of the important elements because technological developments have changed the entire order of military strategy. One of them is the development of military equipment technology part of weaponry. As is known, often Indonesia army soldiers conduct shooting exercises to defend the Nation and the Unitary State of the Indonesian People (NKRI). With the shooting training there is a lot of waste from bullet cladding. Bullet cladding or patrun is an object that is a container that wraps around a bullet projectile and consists of propellant (gunpowder), rim, and primer. Bullets/munitions after firing can still be recycled back into active munitions. In accordance with the purpose of this study, researchers modified a cladding machine in order toimprove the performance of thetool effectively than before. The research methods used are a combination of experimental and empirical manual calculations to determine the relevant results. The result destruction can cut 3 grains of cladding even more in everyone round of the cutting blade, so this study modified the transmission system, fixed clutch, shaft, straight gear. The transmission uses a1:60 wpa gearbox ratio, with an electric motor drive power of 1.5 kW/ 2 HP, 1450 r / min, using a flange type clutch.
工业革命4.0时代，军事力量成为重要因素之一，因为技术发展改变了整个军事战略秩序。其中之一是武器装备部分的军事装备技术的发展。众所周知，印度尼西亚军队士兵经常进行射击演习，以保卫国家和印度尼西亚人民的统一国家。在射击训练中，子弹包层会产生很多废物。子弹包层是包裹子弹的容器，由推进剂(火药)、边缘和底火组成。子弹/弹药在发射后仍然可以回收回现役弹药。根据本研究的目的，研究人员对包覆机进行了改进，以便比以前有效地提高工具的性能。使用的研究方法是实验和经验人工计算相结合，以确定相关结果。结果破坏可切割3粒以上覆层在每轮切割叶片，因此本研究修改了传动系统，固定离合器，轴，直齿轮。传动采用a1:60 wpa齿轮箱比，电机驱动功率1.5 kW/ 2 HP, 1450 r / min，采用法兰式离合器。

The combat vehicles that Indonesia Army belong to most of the materials are steel, for example the armored vehicle anoa 6x6. Steel material is used as a fire protection on the vehicle, it will greatly affect the performance of the vehicle. It is caused the steel material has a high density, which is around 7750 kg/m3to 8050 kg/m3. So, with a large enough volume of the vehicle body, it will increase the burden of the vehicle. As well as the engine load will increase, and more power is needed to be able to move the vehicle. Seeing these problems, it is necessary to have a research or study on alternative materials to replace the body of a combat vehicle that can withstand fire from opposing weapons that cause personnel to be injured. In this study, experimental and simulation methods were used using the ansys application to analyze the strength of the composite material in the form of an aluminum layer that had been treated to increase the hardness value. Furthermore, it is coated with a composite material using a carbon fiber matrix of epoxy, HGM and polyurethane. The coating material is called Fiber Metal Laminate (FML), so the material used has a lighter density, the load received by the vehicle engine is lighter, and the performance of the vehicle will be more effective and efficient.

Abstrak: There are many streams of water or rivers around us which are felt to be underutilized effectively. Therefore, it is necessary to develop Pico hydro technology as an alternative to power generation. Pico hydro usually produces low wattage so that it is not optimal for people to use in their daily lives. Therefore, the design of a power plant is designed that is equipped with an ECU control system as a water source control system that can produce greater electrical energy. The research method used is a pure experimental method to find out the results obtained are 300 watts by calculating the pressure sent to the ECU system. Technically, Pico hydro has several components in it, such as waterwheel water as a turbine, steering blade and generator. Pico hydro can be used as an alternative energy that utilizes the flow of water which can be used as an energy source. The Pico hydro generator used in this study is the Brantas River in Pendem Village, Karangploso District, Batu Malang City. With adequate water flow, using a Francis type water turbine, and using a 200Watt generator and controlled by the ECU system. From the test results obtained potential energy of 5880 (Nm), compressive energy of 2.107 (N/m2) pipe flow velocity (v) 7.668 (m/s) energy contained in water 45.67 (watts) Francis turbine efficiency 31.97% generator efficiency is 28.77% and the maximum power produced by a 200 watt generator is 29Volt

Abstract: In the military world, battle technology has experienced very rapid development, both close-range combat and long-range combat. In long-distance combat the technology that is often used is rocket technology where this rocket technology can paralyze the enemy in large numbers. Black powder is a mixture of potassium nitrate (KNO3), carbon powder (C) and sulfur (S). (Evie Lestariana, LAPAN). The black powder itself functions as an igniter filling material for the propellant combustion process. This research is to design a tool to support the manufacture of black powder in the igniter filling to help the combustion of rockets, especially those owned by the Indonesian Army. This study uses an experimental method using empirical calculations to get a tool with the desired specifications. Before carrying out the calculations, the author collects research data to carry out calculations, the data collected are as follows: 1. Roller shaft rotation: 246 rpm, 2. Roller shaft torque: 4.0697 Nm, 3. Roller shaft diameter: 25 mm, 4. Pulley shaft diameter top: 100mm. The results obtained after carrying out the calculations are the diameter of the driving pulley 98 mm, the belt contact angle against the pulley 174.6º, and the length of the V-belt 453.14 mm, moment of inertia on the gearbox output shaft 1884,8 mm4.
