Abstract

Minimarkets face challenges of overcrowding and prolonged wait times, often due to suboptimal cashier staffing. This study aims to determine the optimal number of cashiers to minimize queues. Using a single-phase multi-channel queuing model, data was collected through direct observation and quantitative analysis. Initial findings with two cashiers revealed varying wait times, prompting simulation experiments. Results indicated that adding a third cashier significantly reduced wait times to 0.41-2.45 minutes, enhancing service efficiency and customer satisfaction. Future research may explore longer observation periods and assess cost-effectiveness in staffing adjustments. Highlight: Data Analysis: Direct observation, quantitative data, and Excel processing for insights. Simulation Test: Arena software simulates cashier scenarios for service optimization. Efficiency Boost: Adding a cashier reduces wait times, enhancing customer satisfaction. Keywoard: Minimarket, Queuing Model, Cashier Optimization, Service Efficiency, Customer Satisfaction.

Abstract

PT P, a sugar manufacturing company, has a sugar factory located in the Sidoarjo area. SHS sugar and quality manufacturing company. Production problems often cause long production delays, therefore managing the production process is very important. Failure modes and effects analysis (FMEA) was used to determine possible failure modes of sugar production. In the test results, various kinds of problems were found: transportation, grinding, purification, evaporation, crystallization. There are 5 factors that cause production inefficiency, namely: human factors, word methods, environment, raw materials and machines used. This resulted in that when the sugar production process was not optimal at PT P, the FMEA method was used to minimize production constraints in order to achieve production targets. After observing using the FMEA method, a value of 480 was obtained in the milling process.

Abstract

General Background: Warehouse layout plays a critical role in supporting material handling efficiency and operational performance in industrial systems. Specific Background: The studied company experienced excessive travel distance and disorganized item placement, leading to inefficiencies in retrieval and storage activities. Knowledge Gap: The existing warehouse arrangement had not applied a systematic storage classification based on item movement frequency, resulting in suboptimal space utilization and material flow. Aims: This study aims to redesign the warehouse layout using the Class Based Storage method to minimize travel distance and improve storage organization. Results: The analysis classified items into movement-based categories and proposed a new layout configuration that reduced total travel distance compared to the initial condition. The redesigned layout also improved accessibility for high-frequency items. Novelty: The study demonstrates the practical application of Class Based Storage in a specific industrial warehouse context supported by quantitative travel distance analysis. Implications: The findings provide a structured reference for warehouse management strategies focused on layout planning, storage classification, and operational efficiency improvement within industrial engineering practices. Keywords: Warehouse Layout, Class Based Storage, Travel Distance, Material Handling, Industrial Engineering Key Findings Highlights Storage classification based on movement frequency reorganized item placement systematically. Proposed configuration lowered total material transfer path compared to the initial arrangement. High-rotation products were positioned closer to access points to streamline retrieval activities.

Abstract

General Background: Facility layout design is essential in supporting operational efficiency and smooth material flow within production systems. Specific Background: Ineffective layout arrangements often lead to excessive material handling distances and inefficient workflows in industrial environments. Knowledge Gap: Previous studies have not fully integrated relationship-based analysis and visual layout representation to systematically improve facility arrangement. Aims: This study aims to redesign facility layout by analyzing activity relationships and developing an improved layout configuration using Activity Relationship Chart (ARC) and Activity Relationship Diagram (ARD). Results: The analysis identified key relationships among workstations, which were translated into a structured layout design that reduces unnecessary movement and organizes workflow more effectively. The proposed layout demonstrates improved proximity between related activities and better spatial arrangement compared to the initial condition. Novelty: This study provides a structured application of ARC and ARD integration to connect relationship analysis with visual layout design in a specific industrial context. Implications: The findings offer practical guidance for improving facility layout planning to support more organized production flow and reduced material handling inefficiencies. Keywords: Facility Layout, ARC Method, ARD Method, Material Handling, Layout Redesign Key Findings Highlights Activity relationships guide spatial arrangement decisions Workflow organization reduces unnecessary movement Proposed configuration improves proximity among work units
