Abstract

The processing of “pisang sale” that exist in today's society is traditionally done by putting a banana in the embers of charcoal. Fumigation with burning in the open space takes a long time to cure the bananas which ranged from 20-24 hours with inversion every ± 4 hours.Drying equipment system consisting of a combustion chamber, heating ducts, drying cabinets and chimneys is necessary for the utilization of the heat of combustion energy can be used optimally. an equipment system that has more than one dimension is very difficult to do the heat transfer. Therefore, a numerical method of choice to resolve this case, which concerns the system with the properties of complex physical and unevenness boundary conditions. This method usually requires a lot of time, especially if it manually, but with the development of technology computerized numerically settlement is very easy and fast with computer software. The results of mathematical calculations using Gauss Jordanmodels, then the calculated temperature value obtained for T2 - T9 are respectively 95.635; 86.991; 81.338; 77.024; 73.733; 71.186; 68.819; 67,2730C.Calculation of more, complicated or complex, numerical solutions by computational methods into a very appropriate choice.So that the results can be obtained in a short time.

Abstract

The capacity of energy storage and temperature storage has come into consideration in choosing thermal energy storage system. Absorbed or released material either big or small can be determined by finding the value of the specific heat (Cp) and the latent heat fusion (HL). The selection of materials suitable for Phase Change Materials (PCM) latent heat storage system is the most difficult but the most important thing. The determination of specific heat (Cp), latent heat (H) and thermal conductivity (k) of the PCM is very important in order to assess its performance for the process of developing a good and superior PCM. with a lot of bee-wax materials which is in the district of Aceh Besar province of Aceh, the bee-wax materials of this need to be investigated for long-term goals as a PCM. In this study, T-history method is used to determine of specific heat (Cp), latent heat (H) and thermal conductivity (k) of the bee-wax materials. The results of calculations using the T-History for bee-wax materials obtained Cps at 0,03 KJ/Kg.K ; Cp,l at 3,45 KJ/Kg.K ; Hm at 307,15 KJ/Kg ; k at 0,262 W/mK. Based on these data, the bee-wax in Aceh Besar district can be used as a Phase Change Materials (PCM). Keywords : bee-wax materials, T-history method, specific heat, latent heat, thermal conductivity
