Abstract

ABSTRACT Every month telephone users pay their telephone bill in TELKOM outlets or banks. Nowadays, Bank X Surabaya has 2 (two) telephone bill payment windows with long queue. In this case, the computer simulation model is used to find an effective queue system to anticipate customers’ dissatisfaction. Using Software Arena and Simul8, the model system is simulated into software to describe how the system works. The real system simulation  shows that the average of  utilization level of 2 telephone bill payment windows are  94% and after trying  3 telephone bill payment windows in trial and error simulation, it shows that the average of  utilization level  reduce to 36%, so that customers’ satisfaction increase. Keywords: simulation, queue, amount of telephone bill payment window

Abstract

As a product, grass paving has its own characteristic. The producers always try to keep the quality of their product to satisfy their consumers. This research tries to identify some factors that determine pressure strength of grass paving and some dominant factors generate optimum pressure strength and to recommend the ideal material composition to produce a good grass paving. The research shows    portland cement composition (A), water (B), sand (C), and ash (D) determine the pressure strength of grass paving. The combination   level factor:  2.7 kg portland cement , 0.9 lt water , 1.0 kg sand , and 2.0 kg ash  generate optimum pressure strength of grass paving. The SN ratio is derived from  2.7 kg portland cement , 0.9 lt water , interaction  between 2.7 kg portland cement  with 1.4 kg sand , and interaction between  2.7 kg portland cement with  1.0 kg sand. Keywords: Taguchi method, pressure strength, grass paving.

Abstract

AbstrakPersaingan antara industri yang satu dengan industri yang lain sangat ketat sekali untuk menghasilkan produk yang diinginkan pasar. Keberadaan kualitas suatu produk menjadi sangat penting agar produk diterima dipasar. Tujuan penelitian ini adalah untuk mengidentifikasi kesalahan manusia yang mempengaruhi ketidaksesuaian kualitas produk dan faktor – faktor penyebab terjadinya kesalahan manusia (human error) pada bagian  kantong kraft lem (pasted bags). Metode Human Reliability Assessment (HRA), sebuah metode pengukuran kinerja yang bertujuan untuk mengetahui keandalan manusia dalam menangani tugas yang diberikan padanya. Dalam metode Task Analysis untuk menganalisa tugas yang dilakukan oleh operator dalam mengoperasikan mesin Bottomer dan mesin Tubber. Untuk mengidentifikasi dan klasifikasi human error dengan Fault Tree Diagram yang bertujuan mengetahui bagaimana cacat produk terjadi karena kesalahan manusia dan analisa menggunakan Cut and Path Set untuk mengetahui apakah setiap basic even sudah mampu menghasilkan produk cacat. Berdasarkan hasil penelitian ini menunjukkan bahwa faktor dominan yang perlu diperhatikan oleh perusahaan adalah ketersediaan ruang gerak untuk bekerja yang ditunjukkan oleh nilai Normalized Raw Weight tertinggi 0,0613354, sedangkan faktor terendah yang berpengaruh pada kinerja operator dengan nilai Normalized Raw Weight: 0,0326744 yaitu shift kerja yang disediakan. Disamping itu, warna tinta supplier memiliki nilai Probability Of Failure (POF) tertinggi 0,2745 dan terendah dengan nilai 0,2745 adalah penyetingan mesin. Kata Kunci : Kualitas produk, Human error, Human Reliability Assessment.

Abstract

Simulation is one of the tools to solve the problems in a system, including hospital systems. The hospital has objectives and entities that are different from other systems, namely service to patients (humans) primarily, so making some decisions requires consideration due to the complexity of the variables within them. This preliminary study will discuss what problems might occur in the hospital and how the application of the simulation in solving the problem. Based on observations and interviews conducted, it is known that there are four issues: 1.) hospital services 2.) labor allocation (nurses) 3.) capacity and number of rooms/beds 4.) drug supply. Based on the literature search results, it is known that the simulation has the ability to solve these problems. The results of this literature review will then be used as a basis for developing simulation models in hospitals which are the object of research.
