Abstract

PT. Pelindo Sorong is a company in West Papua that offers loading and unloading services using containers. Although the company has implemented  a queue distribution pattern in handling containers, it needs process improvement.One method to overcome is problem is to use Promodel 2016 software and SPSS version 22 as a tool to determine the optimal timing of the ideal loading and unloading process. The container handling equipment observed in this study were a crane, tractor trailer and reach stacker. The field survey in February 2020 was conducted to measure the handling time of dry containers.The simulation results show that the optimal average loading process is 2.32 minutes and the loading process time is 3.08 minutes. And the highest level of utility for the loading process is 25.24% and for the loading process is 53.30%. From the analysis using promodel 2016 software, it is known that the highest utility value of the two processes is below 100% so that there is no bottleneck. If the utility value of both processes reaches 100%, there will be a rush in the queue system. The solution is the there must be additional tools in the process with a high level of utility.Keywords: Containers, Loading and unloading equipment, Promodel 2016, Optimal    average time

Abstract The purpose of this research is to measure student satisfaction with the information provided by the Unsrat Inspire portal service using fuzzy servqual and Importance Performance Analysis (IPA) methods by conducting surveys through questionnaires. The stages of this research are starting from studying existing literature to become the basis for taking questionnaires, processing data to drawing conclusions. From the results of the study, it was found that all statement attributes gave negative values, although not too large, which meant that students were still not satisfied with the inspire portal service. It can be seen from the table that the top five that get the biggest negative value are the security of student data on the Unsrat Inspire Portal (-0.57), the accuracy of announcement information on the Unsrat Inspire Portal (-0.57), making it easier for students to find exam schedules (-0.48), the accuracy of lecturer information provided to students through the Unsrat Inspire Portal (-0.46), and the features on the Unsrat Inspire Portal are complete (-0.45) while from the Importance & Performance Analysis diagram there are 2 service attributes that are in quadrant I which means that these attributes must improve their services. Keywords: Inspire portal, integrated information system, fuzzy servqual, Important Performance Analysis.
