Abstract

Thermosypon are heat exchangers in the form of a pipe that consists of three main parts: evaporator (the bottom of the tube), adiabatic and condenser (top tube). Evaporator part is the part that receives heat and absorb them to be brought goto the condenser, the part which releases heat to the environment. Among the evaporator and condenser there is a section that separates, ie adiabatic section as part of an isolated so no temperature exchange with the pipe lingkungan.Didalam there is the working fluid that carries heat from the evaporator evaporator.Panas absorbed from the environment and move up the tube because of differences in density between the vapor and liquid to kesisi condensation (condenser) and heat dilepaskan.Pada side vapor condensation condensed into liquid and moves down back to the evaporator because of the force of gravity.In this study, thermosypon made of copper with a diameter of 12,7 mm and a length of 500 mm with a length of 195 mm condenser. The area subject to the evaporator as the heat source side, adiabatic section is isolated so that no heat exchange with the environment and the area condenser mounted heat sink which aims to remove heat from the heat pipe to the environment. The research was done by varying the concentration of the working fluid, the concentration of the mixture of acetone and ethanol.Variasi fluid mixture concentrations used in this study is the percentage of acetone to methanol, yaitu0%, 20%, 40%, 60%, 80% and 100%. The data required is the temperature at the evaporator (Te), the temperature of the condenser (TK1, Tk2, TK3) and air temperature (Tu).The results showed that, most small thermal prisoner at the time of the concentration of 100% acetone to ethanol. At the same acetone concentration, the higher the power (the higher the temperature), the greater the heat flux and power output. The process in this experiment the largest output power and capacity terbesarterjadi the acetone concentration of 100% and the highest power (63 W).

Abstract

This paper discusses the soft clay soil stabilization with lime on the condition of the water content of the field. The sample used is soft clay of Marabahan, Barito Kuala, South Kalimantan. The water content of the sample is initially 76.2%. Samples were mixed with natural limestone that has been crushed and screened through a sieve No. 20 the percentage of 4, 8, 12, 16, and 20 percent based on the dry weight of the sample. Samples were mixed with lime cured for 7 and 14 days. Some of the tests performed in the laboratory include testing soil plasticity, direct shear tests, unconfined compression test, vane shear test, consolidation, and CBR. The results showed a decrease in the values of soil plasticity (liquid limit and plasticity index) and soil compression parameters (cc and cs) with the increased percentage of lime. While the values of cohesion, friction angle in, qu and qr, and CBR increases with increasing percentage of lime. The results also showed that the curing time effect on soil parameters were mixed lime.

Abstract

Welding is a process of joining metals by pressure when the metal are hot. Welding planning to get a good result is a complicated process. A welding work should be planned about its way, observing the material and its type of welding. The procedure of welding involves: choosing parameter of welding type of being used, type of filling metal, type and also the thickness of metal plat and condensor as mediator and some standartd condition in welding in which the parameters will effect the mechanical characters of welding.An example of welding type is Oxy-Acetyline Welding (OAW). The heat being produced is lower, so this kind of welding is good to weld the thinner stainless steel ( 3 mm). The thicker one needs a longer welding time so that, it is not economic. This kind of welding is good for a thick stainless steel before using electrical welding. This welding is used for a simple construction that is not need strength, example in the fenceof a house or for welding a house hold.This process, uses material of  ST-37 steel plate with 3 mm thickness. Weld with 1-2 mm in space between thew both material. Set the barometer up on the acetyline bottle is about 0,5 bar and the pressure on oxyigene bottle is about 2,5 bar, and a weather condensor. Use RBuZn-A, RBuZn-B and RBuZn-D as filling metal. Then do test.
