Abstract

One of the main factors in securing an electric power system is the earthing system. The earthing system in the generating unit is closely related to the switchyard. Switchyard earthing system analysis is done by adjusting the grid distance and ground rod length to get the most optimal quality and cost combination. The definition of optimal conditions in this case is limited to circumstances where there is a combination of quality that does not exceed the technical tolerance threshold and has cost efficiency. The analysis of the switchyard earthing system was taken as a case study. Calculation results and analysis concluded that the grid distance of 23 m and the length of the 6 m ground rod is the best choice in the optimization of this earthing system by meeting the safety quality criteria for earth resistance is Rg = 0.13806 Ω less than 0.5 Ω with a minimum cost of Rp. 1,220,104,730.Technical standards are carried out based on IEEE Std 80-2000. Calculations for obtaining technical parameters and costs are carried out one-by-one in the range of grid spacing and length of certain ground rods to determine the optimum point using MATLAB-GUI as a programming tool and MATLAB R2011a as a tool mathematical computing.

Abstract

Regenerative Drive is a motor drive system in an elevator that can also generate electrical energy while consuming electrical energy in the elevator machine, Regenerative Drive converts gravitational potential energy into electrical energy by utilizing the operating characteristics of the lift and the weight difference between the lift cage and the load balancing (Counterweight). ). The resulting regenerative power is recovered by returning to the building electricity and being used in other electrical equipment. Regenerative drive lift test location is located in Building which has an elevator using Regenerative Drive. With a motor power of 38.6 kW and can produce regenerative power of 29 kW.

Abstract

Needs consumer will tool transportation train fast fire on time now has sue Railway Corporation for Upgrade service and comfort for satisfaction para para consumer use tool transportation this in activity everyday. Look importance needs consumer will comfort use tool transportation train fire, then Writer interested for discuss comfort in journey train specifically problem journey train fire with elevation rail  in pass Bend moment drove. Analysis done from Railway Corporation with literature assistance regarding problem railway. Remember breadth existing problems on train fire, then Writer limit only on calculation point heavy carriage, the forces that occur, and balance carriage when turn without and existence rail elevation. From result analysis carried out elevation data is taken rail maximum by 110 mm, radius curvature, speed plan maximum 120 km/h. Generate speed data critical in bend without elevation rail, and speed critical in bend existence rail elevation.

Abstract

The processing of Fresh Fruit Bunches into crude palm oil and palm kernel can be done by starting to boil the Fresh Fruit Bunches until they are ripe, after the Fresh Fruit Bunches are ripe, then separate the bunches from the fiber by going through the slaughtering process, after which the fiber is then chopped and immediately pressed so that the oil comes out. After the oil and fiber are separated, the fiber will go to the fiber cyclone. Fiber cyclone is a device located at the solids station, the main function of the fiber cyclone is to separate the nut and fiber by sucking the fiber using air, through the ducting column and will exit through the air lock and then go to the boiler to be used as fuel. The fiber cyclone has a speed of 10.08 m/s for the velocity box, a vertical column of 6.86 m/s, and 8.57 m/s for the horizontal column. Fiber cyclone has 1 loss point for kernel, what is analyzed is the output of fiber cyclone which is fiber taken from air lock, the standard loss for fiber cyclone is 0.10%.
