Abstract

The weapon system's modernization is expected to anticipate a very conditional and fluctuating defense situation. One is developing Medium Altitude Long Endurance Unmanned Aircraft (PTTA MALE) vehicles by completing weapons systems to strengthen the national defense system. This study analyzes the technical specifications of weapons systems that meet user needs at PTTA MALE. This study uses qualitative and quantitative methods with research analysis using a Quality Function Deployment (QFD) approach. The analysis is carried out based on the priority scale value reference from the technical specifications of the user requirements. The research results obtained priority scale of operational requirements and technical specifications of weapons systems based on Benchmark Performance (BP) values, namely weapon load (84.31%), warheads (80.39%), guidance systems (68.63%), sensors ( 68.63%), target distance (68.63%), based on independence (63.40%), target type (63.40%), and explosion range (49.02%).

Abstract

Natural fiber composites are an alternative Multilayered Armor System (MAS) material. One of the most common natural fibers used as MAS is a fiber made from bamboo rope. Bamboo fiber composites have a low density and a low manufacturing cost. However, in terms of mechanical properties, bamboo fiber composites have different characteristics. In this research, the mechanical properties of the bamboo rope fiber composite, which has an orientation of 0°/90°, will be analyzed. The composite materials used are bamboo rope fiber as a reinforcement and epoxy as the fiber binding matrix. From the mechanical tests performed, it was found that the average tensile strength of the bamboo rope fiber composite was 109.86 MPa. The bending strength is 95.32 MPa, and the shear strength is 34.11 MPa.

Abstract

Utilizing a nuclear propulsion system as a source of propulsion is one method for extending the durability of warships. Compared to using natural oil, using nuclear energy as a propulsion system offers a high effectiveness value. The Molten Salt Reactor illustrates a reactor design that can be utilized on warships (MSR). The current MSR is still quite big. Therefore in this research, an optimal design of the Small Modular Molten Salt Reactor (SM-MSR) core will be adapted to the surface area of ​​a warship. From the simulation and optimization carried out with the MCNP software, the parameter used as a reference is criticality. The optimal fuel material composition is 1% Li and 2% U-235, with an optimal design geometry having a cell core pin radius of 0.8 cm, a pin cell blanket radius of 2.6 cm, and a core height of 160 cm. The initial design of the SM-MSR in this study had a negative coefficient of void reactivity.

Abstract

This research uses the finite element analysis method to examine the design and safety analysis of the bracket roll brush. The problem occurs when the bracket roll brush is deformed during the wetting process, which impacts the printout of the product, where the ink dirt is still attached. The bracket roll brush uses 6061 T6 aluminum material of 38 mm x 25 mm x 19 mm, and the weight generated from mass properties is ± 0.03 Kg. The loading variable on the bracket roll brush is 147 N, 172 N, and 196 N. The simulation results show that the bracket roll brush has a maximum stress value of 85.551 N/mm2, and the value at the maximum stress of the bracket roll brush is still below the material yield strength value of 275,000 N/mm2. The simulation results on the bracket roll brush have a maximum displacement value of 0.0035 mm. And the simulation results on the bracket roll brush have a minimum safety factor value of 3.214.
