<![CDATA[Blood is the fluid found in all living things serve to transmit substances and oxygen needed by body tissues, carrying chemical products of metabolism, as well as the body's defense against viruses or bacteria. If blood will be donated to another person, the blood will be stored in a blood bag and should be used immediately to the recipient blood. If it is not used directly as they are not needed or should be taken to another place, it must be kept comfortable. Because storage temperature greatly affects the quality of the blood and age of stored blood. Blood storage temperature range from 1 oC to 6 oC, for this reason, it is necessary that both the thermal insulation material storage chamber walls of blood to maintain the desired temperature.

<![CDATA[The amount of agricultural lands has been converted into residential land and industrial land since a lot of farmland in the mountains has been opened. Groundwater and river has been used to irrigate the agricultural lands. Farmers in the mountainous areas typically use his physical effort to get water from river to agricultural land. This causes inefficiency of working for farmers thus the agricultural productivity is not optimal. Owing the fact that agricultural land is far from the electricity resources (PLN) therefore a small capital farmer must use pump to irrigate their agricultural lands. Hence, farmers have to spend big amount of money to buy fuel to drive the agricultural pump engine. Thus, it is necessary to have a specific research on the availability of wind energy in order to mobilize the agricultural pump engine in the mountainous area. In this case, the authors have calculated and analyzed the potential of wind energy to drive the pump in the village of Sare, Aceh Besar. From the analysis it has been obtained that the average wind speed of 6,41 m/s with the diameter of rotor turbine about 3 meter result in 1005,26 watt of wind turbine power. This power can be used to power a 20 m head static pump, requiring 650 watt to provide irrigation for 19 hectare of agricultural land 7 hrs/day. HOMER and Epanet 2.2 software are used to conduct simulation for power system generation. The result of HOMER simulation shows the lowest NPC value of US$ 10.028 with the cost of energy (CoE) of USD 0.717 kWh. The system could produce electricity power in a year of 3.452 kWh and the working length of the generating power system is 15 years]]>

<![CDATA[Lives of traditional salt farmers increasingly concerned about the unfavorable business caused by the difficulty in obtaining fuel. The use of traditional stoves for salt farmers also without a good smoke channel, making smoke pollution that is harmful to health, and also interferes with the farmers and the environment while producing salt. Therefore, it should be considered a solution to address both of these issues by improving the combustion process that occurs in the combustion chamber and by utilizing the exhaust gas heat as a preheater in the salt process. Good combustion requires sufficient air supply with a certain excess air so that the combustion process is perfect. Air supply can be done by utilizing the natural drought affected by the height of the chimney. Utilization of flue gas has been done by creating a configuration flue gases channel through the multiport stove. Testing with chimney height variation needs to be done toget the optimal height so that stove can work with a good performance to produce salt. The results showed that the optimum height of the chimney in the semi-modern salt stove is at a height of 1.55m with a thermal efficiency of 48.6%.]]>
