Abstract

This paper proposed a queue model for beverage order picking system produced from agricultural commodity in warehouse with drive-in rack system in order to analyze and increase the warehouse performance. A (M/M/C):(GD/N/∞) queue approach was used to build the model with the queue approach. This paper considered total operator must-be-assigned to improve queue time (Wq), queue length, and utilization in the warehouse.  Stack, queue, linked list, Colour HSB (Hue, Saturation, Brightness) algorithms were used to represent drive-in rack, product queuing, and product status in the warehouses. The model was implemented in computer simulation using java programming. After build the model, a real case industrial problem was presented to test the model. The model could calculate warehouse performance including low performance in racking, transportation to loading area, and loading process for current number of operators and idle operator in the warehouse process. This result was in line with the industry condition that has over capacity and high product bottlenecks in the warehouse. The model was used to find and analyze total operator-must-assigned to increase the warehouse performance. The computer simulation showed colour changing based on density of product stack in queue area. This colour degradation helped for easier understanding and accelerating product status detection (including hold, ready-to-release, and expired beverage products in the warehouse).Keywords:beverage warehousing, drive-in rack, order picking, queue modelling, queueing theory

Abstract

Synthesis of diethanolamide (DEA) surfactant from palm olein methyl esters has the potential to commercialization. This surfactant product can reduce surface water tension from 72 dyne/cm to 33.82-32.06 dyne/cm in laboratory scale and the synthesis process was 50% cheaper than palm kernel fatty acids. So that, it is necessary to review the surfactant DEA production from palm olein methyl esters. The purpose of this research was to get the best synthesis process of DEA surfactant on 25 L/batch reactor. The synthesis process of DEA surfactants was divided into two stages. The first stage was conducted to determine duration and stirring rate of the DEA surfactant synthesis process. Then the best result in this first stage was continued in the second stage of the synthesis. The second stage was conducted by using an installed bulkhead in the reactor and some agitators for the DEA surfactant synthesis process. The lowest value of surface tension was the main parameter that was used for determining the best synthesis of DEA surfactant. Based on the first stage results, it was known that the best synthesis process was 4 hours with 100 rpm stirring rate. In the second stage, it was concluded that the best type of agitator was propeller. The best surface tension of DEA surfactant resulting from this research was 14.28 dyne / cm. The other parameters produced from the synthesis process were yield of 95.24%, viscosity of 245.41 cP, density of 0.973 g/mL, and pH of 11.1.Key words : DEA surfactant, diethanolamide, surface tension, synthesis process
