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

This research aims to study the effect of climate engineering on the growth of strawberry plants in the lowlands. This research was conducted in greenhouse media of 6 m2 wide and 2 m high with roof cover and wall of ultraviolet plastic with roof damper using straw. Types of strawberry plants that will be used are varieties of strawberries (Alpine) Red and White Mixed. The planting medium of strawberries uses a polybag placed on the shelf. The analysis discussed in this research is the analysis of temperature and humidity attainment and growth and development of strawberries. Temperature and humidity attainment is indicated with fixed temperature and humidity data of 17 0C – 20 0C and 80% - 90% Rh under all conditions. Strawberry growth analysis is indicated by increasing stolon size while development is indicated by a change in fruit form.The results showed that the greenhouse room during the day only able to reach an average temperature of 22 0C and 70% moisture. While in the morning and afternoon greenhouse space is able to reach the temperature and humidity of strawberry habitat. Using temperatures and humidity under the design, strawberry plants are still alive and well developed which is indicated by the addition of stolon length, the appearance of new shoots, fruit ripening, and the addition of strawberries.

Abstract

The air distribution system in the room has the task of flowing cold or hot air into the room, a comfortable room condition is at a temperature of 24˚C. This study aims to determine the effect of the speed of the blower rotation on the performance of the car's AC. The cooling system in the vehicle, uses a blower to distribute cold air produced by the evaporator. Many choices of speed blowers to distribute cold air. In this study using variations in the speed value of blowers. Blower speed greatly affects the room / cabin temperature. Avoiding excessive energy consumption or inefficient energy consumption is indicated by a decrease in the COP from a cooling machine. After research obtained efficiency data for low blower rotation speed of 73.36%, medium rotation of 72.86%, and high rotation of 72.83%. But the fastest cooling of the cabin uses a high speed blower rotation. Keywords: Performance, Car AC, Speed Blower, Temperature
