Abstract

In this research designed an air conditioning system that is capable of reaching temperatures needed in the pasteurization process in miniature kumbung. The temperature required is approximately 70-80oC. The temperature was maintained for 4 hours. To maintain at that temperature control system designed 'on-off' by using a microcontroller ATMega 8535. This system works by shutting down the system when the temperature has been reached and revive the system when the temperature has dropped to the lower limit temperature setpoint. The results of this research in terms of the time required for the pasteurization process kumbung automatic mushroom faster at less than 5 hours compared kumbung regular mushrooms is 7-8 hours.

Abstract

Stirrer system has analyzed the homogeneity of Uranium Penurnian Installation unit which serves to change the yellow cake (natural uranium) into uranium UO2 powder. in this system of natural uranium in the form of effluent UO2 (NO3)2 maintained homogeneity, with a surface elevation level fixed tank. Uranium purification system involves two (2) tanks interplay output, so the output is obtained in accordance with the sett-point value, then the system needs to be in decoupling. Then the control system is applied to the height of the tank using decouling Level control with shift method eigenvalues.

Abstract

Temperature and air circulation is an important factor in a building since it is closely related to health comfort. Therefore, the design of a building should be carry out precisely in getting a clean, healthy and comfortable air circulation in accordance to the requirement of the room.In order to carried out a good building designing, a research was needed to understand temperature distribution, the pattern of air flow and its velocity. In this research, a Classroom of TN II JTF UGM. This classroom have 1030 cm length, 790 cm of width, and 330 cm of height. The size of the windows is 100 x 100 cm and place 1m from the floor. The size of the doors is 140 x 210 cm. The windows are assumed to be widely open, the door always opened. The researched begins with geometric modeling of the model by using Gambit 2.2.30 and continued with model testing using Fluent 6.2.16. The test is carried out by giving three velocity variation of free air flowing i.e.: from 1.3 m/s, 3.61 m/s and 5.92 m/s, two direction variation of open air flowing and two variation temperature of free air i.e.: 21.50C and 27.650C.The standard of comfortable air velocity used in the room is 0.15 < V < 0.25 m/s, The standard of comfortable temperature used in the room is 20.50C and 27.10C. The air velocity and air temperature variation created comfort area and non comfort area in the room .The direction circulation of air variation created the different pattern air circulation in the room.

Abstract

Conventional cooling systems based on vapor compression have a high coefficient of performance (COP). However shortage of vapor compression cooling systems still using refrigerants that have detrimental effects on the environment. For that purpose, the research of fruit and vegetable storage machine using thermoelectric system TEC1-12706 with temperature control system using arduino. In this study the temperature in the cabin can be stable at 15° C and still feasible for use as a storage of fruits and vegetables.
