Publisher : Universitas Mercu Buana, Prodi S2 Teknik Mesin

Pressurization system in fire stairs is required for high-rise building for safety evacuation in fire attack. This paper has highlighted on the problem of WTC 6 high-rise building with 18 floors related to safety evacuation in fire attack. In real situation, the minimum air pressure (12.5 Pa) at closed condition and minimum air velocity (1 m/s) at open door chamber in fire stairs as stated in the SNI 03-6571-2001 requirements are not fulfilled by the WTC 6 high-rise building. Therefore, a CFD (Computational Fluid Dynamics) simulation has been used to overcome the problems. The CFD results show that volumetric air flow rate of 7.24 m3/s injected to fire stairs in multiple injection system yielded pressure difference of 39.5–44.7 Pa and air velocity of 1.1–1.2 m/s. The CFD simulation implemented in real situation yields air pressure difference of 38.2 Pa in closed condition and air velocity in open door chamber of 1.16 m/s assumed to solve the problem.

Graphene Oxide is a material that has a thickness of one atom composed of carbon atoms to form a hexagonal lattice and a material that has unique properties, namely mechanical, optical, thermal, and electrical properties. Fe2O3 is a material that has magnetic properties and can be used for various applications such as enzyme separation, drug transport, microwave absorption, photocatalysts, biological applications, biomedicine, metal separation, and magnetic resonance imaging (MRI). In this study, the addition of graphene oxide was carried out using the coprecipitation method on Fe2O3 nanomaterials that had been treated with sintering and non-sintering. The coprecipitation method is the synthesis of inorganic compounds which is based on the deposition of more than one substance together when it passes the saturation point. The purpose of this study was to determine whether the addition of graphene oxide to the Fe2O3 material can increase the magnetic properties of the Fe2O3 material or vice versa. The result was that the sintering treatment on Fe2O3 GO did not have a transforming effect on its magnetic properties, but instead had a changing effect on its magnetic value. However, the magnetic coercivity value of Fe2O3 + GO 700 ºC increased to 0.038 Tesla. Thus, it can be concluded that at a temperature of 700 °C graphene oxide acts as a barrier from external magnetic fields in the opposite direction.
