Abstract

The simulation in this research investigates the possibility of using the walls of the rectorate building on the Bina Bangsa campus to install a wall area solar energy system. The building walls are simulated, becoming a representation of the walls of other buildings. PLTS electricity calculations use an interconnected Solar Power Plant [PLTS] system. Research shows that the building has a wall area of 10,353 m2 which can be used to install solar panels. The total electrical power produced in the area is 2030 kWp or 2.03 MWp. The power is divided into four, namely 630 kWp east of the roof, 535 kWp northwest, 668 kWp southwest and 553 kWp southeast.

Abstract

The lean approach is often used by manufacturing companies to increase productivity in the production area. In this case PT P, a manufacturing company that produces refrigerators, faces the same problem on the unloading process in the final assembly area. The unloading process is the operation to move the finished product from the production line and store it in the finished goods warehouse. Operators in the unloading area have tasks to unload finished products from conveyors which are connected directly from the assembly line and placing them on pallets. Due to the refrigerator is quite heavy a forklift has to use to move the full pallet to the finished goods warehouse which is located next to the unloading area. Once finished the forklift returns to the unloading area with the empty pallets and places them in the unloading area, to be refilled by the unloading operator. Based on the data taken, the cycle time in the unloading process was recorded to be varied and the highest was 33 seconds, exceeding the takt time that had been determined on the production line, which was 24 seconds. This means that there is waste that occurs in the unloading area. The long and unstable cycle time in the unloading process makes the production line disrupted because the conveyor often stops and causes productivity to drop. For this reason, it is necessary to analyze and improve the process with the Lean concept by reducing the existing waste, so that the cycle time becomes stable and smaller than the takt time.
