Abstract

From the research that has been conducted on energy audits in buildings PT. X, to know the profile of energy use and energy savings opportunities, so it can be more efficient and save costs. From the initial energy audit have been implemented acquired Energy Consumption Intensity (IKE) to the total area is still under IKE standards for office buildings. For air-conditioned room is not air conditioned and acquired Energy Consumption Intensity (IKE) is low so as very efficient. By replacing energy-efficient appliances, then there is a chance of saving energy

Abstract

Air conditioning for the building to be used as a car showroom in Jakarta is one thing that is needed to provide comfort and freshness to the workers so that the quality and quantity of work produced optimal . The cooling load can be influenced by various factors , among others : the weather , the condition of the building , the building volume , the shape of the building structure and the building materials used , the amount of ventilation air required , the function of the building , number of occupants , condition the outside air , indoor air conditions .

Abstract

In the measurement process on a machine tool alignment required an alignment as the reference standard.In this case the rod straightener is a measurement tool that is commonly used in metrology laboratories. Inplanning and the alignment rod calibration followed standard JIS B7514, which is described in the standardspecification of the alignment rod which include dimensions, quality and tolerance limits. From the results ofthe calibration are performed on the alignment rod has a classification according to JIS B7514 standardclass (grade) B. Thus the alignment rod can only be used for testing machine tools with high level ofaccuracy that is not high (conventional).

Abstract

Along with the times, the process of managing palm sugar has been developed based on the large scale and how efficient the management process is, in this case the method used is evaporation where the sap is circulated several times for the process of draining the water in the Economizer, for the circulation process there is a pump to be able to accelerating the flow system so that the traditional process continues until the sap becomes half the process (thick sap). For this reason, a gear type pump is used so that it can move fluids with high viscosity. In this case the pump used with maximum specifications, the effective head of the pump installation is 52.1573 ???? and a capacity of 0.001 ????³/s, and the theoretical pump power is 0.098 ????????, while the resulting shaft power is 0.14 ????????, the motor has a power of 0.147 kW . As well as the type of External Gear Pump selected with a rotation of 400 rpm and a power of 0.14 kW.
