Abstract

PT. Bank XYZ merupakan perusahaan yang bergerak dalam bidang industri jasa perbankan. Setiap tahunnya perusahaan mengalami perkembangan jumlah nasabah sehingga membuat nasabah melalukan proses pelayanan perbankan harus menunggu lama untuk mendapatkan sebuah pelayanan di PT. Bank XYZ. Penentuan jumlah Teller optimal bertujuan untuk melakukan analisa dan perbaikan terhadap sistem antrian di PT. Bank XYZ. Hasil pengamatan yang diperoleh di PT. Bank XYZ melayani sekitar 350 nasabah/hari dengan jumlah pelayanan nasabah (Teller) sebanyak 4 orang Teller. Banyaknya jumlah nasabah yang datang melakukan proses transaksi perbankan membuat antrian panjang pada jam-jam sibuk (10.00 WIB - 13.00 WIB) yaitu jumlah nasabah yang menunggu untuk dilayani sebanyak 30 orang. Jumlah Teller yang tersedia dinilai masih kurang dapat melayani jumlah nasabah yang datang sehingga banyak nasabah yang meninggalkan barisan antrian akibat terlali lama menunggu. Jumlah teller yang tidak sesuai dengan kebutuhan nasabah akan memberikan kerugian untuk nasabah maupun perusahaan karena banyak waktu yang terbuang. Penggunaan model antrian dapat membantu perusahaan dalam menganalisis dan merancang sistem antrian agar proses transaksi dapat berjalan secara optimal berdasarkan jumlah kedatangan, lama pelayanan dan aspirasi perusahaan. Hasil evaluasi penentuan jumlah Teller optimal diperoleh jumlah Teller optimal yang sesuai dengan aspirasi perusahaan sebanyak 6 Teller. Jumlah Teller yang tersedia sekarang berjumlah 4 orang sehingga diperlukan tindakan berupa penambahan jumlah Teller sebanyak 2 orang menjadi 6 orang. Penambahan jumlah teller dapat memberikan perbaikan dan peningkatan kinerja kedalam strategi perusahaan dalam meningkatkan produktivitas perusahaan pada umumnya dan peningkatan jumlah nasabah pada khususnya.

Abstract

PT XYZ is a company concerned in the port services, one of which is the loading/unloading of goods using a mobile crane. Based on observations, a mobile crane company owned only one unit and installed capacity company are 92 tons per hour company while the load demand on average 157 tons per hour. From the above data shows that the company can not meet the load demand due to insufficient capacity. In an attempt to adjust the loading capacity and load demand is done with addition of capacity through addition of crane. Forecasting is used as a method to predict the loading demand in the future. Data of forecasting is used as reference in approximating the exact number of cranes. Based on the calculations, crane that needed to solve the problem are two units, so it required the addition one crane. The proposed alternative type of cranes are mobile crane 5 ton capacity and luffing crane 10 tons capacity. The best type of crane are selected using decision theory which use payoff approach, they are payoff profit and payoff risk. From the calculation, the best type of alternative criteria from the payoff profit is Luffing crane with a value 7.75, 10, 2.5, 2.5, while for the payoff risk, the best is mobile crane with a value 4.55; 3.5; 7; 1,75. The best type of crane based on comparative payoff is luffing crane. With the addition of luffing crane loading capacity of 10 tons to 276 tons of companies per hour and can meet the load demand loading/unloading and companies.

Abstract

PT. XYZ is a company engaged in the field of port services that serve the activity loading/unloading dry bulk vessels loaded. Based on the interview with the company known that the arrival of ships per day up to 5 ships with a length of service up to 3 days per vessel is still causing queues on dry bulk terminal. The research method used was the distribution of test data on the number of boat arrivals, the data between the time of arrival of the ship, and the ship service time approaches poisson and exponential distribution patterns to determine the queuing model used. The results obtained by the data of ship arrivals follow Poisson distribution and arrival time data between ship and ship service time follows an exponential distribution with the queuing model M/M/3: FIFO/∞/∞. Calculation of the attributes of the queue is known that λ = 0.7875 μ = 0.3168 with the average number of vessels in the queue Lq ≈ 3.3576 as 4 boats and ships an average time while the system is 7.4202 days. With the aspiration level of company that the average number of vessels in the queue no more than one vessel and the average ship time while the system is no more than 4 days, the queuing problem is solved by giving suggestions to increase the number of dock as much as 1 unit. With this addition then, the average number of vessels in the queue to be one ship, while the average time for the ship to be in the system to no more than 4 days. This condition states that the problem of queues at the dry bulk terminal is in the category as desired by the company.
