Abstract

Penelitian ini mengeksplorasi bagaimana meningkatkan kinerja pemuatan amonia cair di Petrokimia Gresik. Amonia cair merupakan produk yang memiliki peluang besar di pasar untuk meningkatkan profitabilitas perusahaan. Namun, perusahaan mengalami kesulitan untuk meningkatkan penjualan amonia cair karena kendala teknis terkait rendahnya loading rate amonia cair. Penelitian ini mengimplementasikan pendekatan simulasi peristiwa diskrit untuk memodelkan proses pemuatan amonia cair di Loading Station Petrokimia Gresik. Model simulasi digunakan untuk memahami kompleksitas dan ketidakpastian yang sulit diamati di dunia nyata. Selanjutnya pendekatan pareto digunakan untuk mengetahui faktor-faktor penting yang mempengaruhi penurunan kecepatan proses pemuatan amonia. Diusulkan tujuh alternatif perbaikan, dan skenario terbaik adalah penambahan satu operator pemuatan pada setiap shift dan satu loading arm yang dapat meningkatkan kecepatan pemuatan menjadi 7% dari kondisi eksisting. Analisa investasi didapatkan Return on Investment (ROI) sebesar 263% akan diperoleh dalam waktu 1 tahun dan Payback Period (PP) akan menghasilkan sekitar 0,275 tahun. Penelitian ini diharapkan dapat memberikan solusi praktis kepada perusahaan yang digunakan dalam studi kasus sekaligus memperkaya literatur dalam konteks aplikasi simulasi kejadian diskrit. ================================================================================================ This study explores how to improve the loading performance of liquid ammonia in Petrokimia Gresik. Liquid ammonia is considered in this work as the product has an immense opportunity in the market to improve the company’s profitability. However, the firm is facing difficulties to increase the liquid ammonia sales due to technical problems related to the low loading rate of liquid ammonia. This study implements a discrete-event simulation approach to model the process of loading liquid ammonia at the company’s loading station. The simulation model is used to understand the complexity and the uncertainties that are hard to observe in the real world. Then, a pareto approach is used to find out the important factors which influence the speed deterioration of ammonia loading process. Seven alternatives of improvement are suggested, and the best scenario is to additionally one loading operator at each shift and one loading arm, which can increase the loading speed to be 7% from the existing condition. Investment analysis obtained Return of Investment (ROI) of 263% will be obtained within 1 year and the Payback Period (PP) will approximately result in 0,275 years. This study is expected to provide practical solutions to the company used in the case study while enriching the literature in the context of discrete-event simulation applications.
