PT. GE Lighting Indonesia is a manufacturing company that producing lamp. In generally, PT. GE Lighting Indonesia’s producing line consists of 5 machines with buffer allocation storage between machine that have early capacity of buffer1= 1225 units, buffer2= 915 units, buffer3=820 units, and buffer4=545 units. The allocation of these buffer is definetely done with purpose to place output from machine before processed to the next machine. Time difference process in every machine make the stream of production process become less fluent and affecting less maximal throughput. Other cause that making the throughput of production line process less maximal is machine damage factor. Although the preventive maintenance policy is applied in PT. GE Lighting Indonesia remain to be the machine damage cannot be obviated at production process take place. This research will try to redetermine the buffer allocation in PT. GE Lighting Indonesia in order to make the production process more fluent, so that can increase the throughput in production line. The method that is use to redetermine the buffer allocation is simulation approach. The reason why the author use this method is because there wasn’t found a representative and valid analytical model that match with the system.The simulation is done with Promodel 4.0 software. Based on the experiment design and running of simulation, it’s achieved a conclusion that the best alternative buffer capacity is at 900 units (buffer1, buffer2, buffer3, buffer4 has a same capacity at 900 units) with average throughput at 9.651 units/shift. While in the early buffer capacity only produce as many as 9.207 units/shift. Finally, if it’s compared with the early condition, redetermining the buffer allocation can increase the throughput of production line process equal to 444 units/shift.

Orthotic and Prosthetic Instalation of Ortopedic Hospital of production unit in the making of prosthesis orthosis in Indonesia. So far there is no technician status which contains finishing time for all orders which are being processed . This condition causes the delay in order finishing time. Therefore, it needs information system which can make task allocation model (new order) better. After system analysis was done to find out the needs of the system, the information system of the process of prosthesis orthosis product order is designed. The existing system analysis is carried out by using IDEF0 language while the setting up plan for the information system proposed is carried out by using object oriented approach and using UML language.At the database setting up level by using Relational Database Management System (RDBMS) approach needs adjustment from object oriented approach to relational approach, then user interface model are designed later. The next step, program codes were made by giving attention to use case diagram and interaction diagram . From the setting up for information system were found out some inputs in the forms of forms for login, the data of patients, products, raw materials needed, raw materials, order, and technician data. The output were in the forms of early warning for order, order reports, the order slips, the letter of order and the acknowledge receipt of the order. From the validation result to the functions in the application was found out that the functions tested were valid or worked well.
