Abstract

Radar or Radio Detection Ranging is a system of electromagnetic waves to detect and measure long distances. Stealth technology or technology systems that allow objects to be undetected by radar. One of them is Radar Absorbing Material (RAM), a material that has the ability to absorb electromagnetic waves. RAM consists of magnetic and dielectric materials. Barium M-Hexaferrite is used as a magnetic material while Polyaniline (PANi) is used as a dielectric material. Barium M-Hexaferrite synthesis material based on Cilacap Beach Iron Sand and Polyaniline Synthesis material by presenting DBSA. To engineer the magnetic properties of BaM, Cu doping was applied, with an ionic radius of 0.71 nm. BaM and PANi materials were mixed on the blacksteel plate using the spray gun method. The study showed the composition of a mixture of BaM and PANi coatings with a ratio of 26 gr vs 23.4 gr, 23.4 gr vs 26 gr and 15.6 gr vs 15.6 gr and variations in pressure (6.7,8 bar). The test characteristics used hardness test, roughness test, thickness test, and VNA test. In this test, the optimal absorption value from the VNA test was obtained, namely the composition of BaM PANi 23.4 gr vs 26 gr at a pressure of 8 bar with a reflection loss value of -4.6119 dB at a frequency of 11.22 GHz. Keywords: RAM, BaM, PANi,Doping Cu and Spray Gun.

Abstract

This test is to see the performance of the pump in series and parallel installation using a centrifugal booster pump to drain Crude Palm Oil. The fluid flow is monitored by a pressure gauge as a pressure detector and a flowmeter as a flow meter to detect Crude Palm Oil’s flow. Has a reservoir with a volume of 45 liters, and uses a 1 inch galvanized pipe. The largest pressure value is obtained by a series pump circuit, of 6 Psi. While the lowest pressure value is obtained by a parallel pump circuit, which is 3 Psi. At a temperature of 80°C, the largest flow rate produced by a parallel circuit is 60 lpm, while the smallest discharge is produced by a series pump circuit of 32 lpm. Meanwhile, at room temperature, the parallel circuit flow rate was recorded at 17 lpm, and the series pump circuit as much as 12 lpm. The pump with the best efficiency with a series circuit is 97%, while in a parallel pump circuit it is 89%.
