Abstract

- PT. ABC was a manufactur company which on the job of metal coating (ZINCALUME) and painted coating (COLORBOND). Its product manufacturing was carrried in metal coating MCL 2 (Metal Coating Line 2) plant, paint coating or painting product was the most demanded by costumer expecially in MCL 2. So that, it was needed a processing time quickly, For it solution, appropriately with a scheduling. The background of this research was a PT. ABC has not been able to fill all of customer orders, because MCL 2 machine was be still new, and has not been sequenced that caused bottleneck. Method of this research was a branch and bound and neighborhood search algorthm. The purpose of this research was to minimize mean flow time at MCL 2. Existing scheduling which used by the company was a FCFS (First Come First Served). New scheduling would be divided the products into two batch which based on dimensions that were, 0,20 x 914 mm and 0,25 x 914 mm. In existing conditon, mean flow time on dimensions of 0,20 x 914 mm and 0,25 x 914 mm were 43,23 hours and 182,76 hours. The research’s result of mean flow time proved that the new scheduling by using branch and bound and neighborhood search algorthm on batch of 0,20 x 914mm was 18,42 hours, with its sequencing was a job 14- job 21- job 20- job 11- job 15 – job 8- job 3 –job 4- job 9- job 7, and then, with a neighborhood search, its sequencing was a job 14- job 20- job 21- job 11- job 15 – job 8- job 3 –job 4- job 9- job 7. For the bacth of 0,25 x 914mm , on branch and bound algorthm, it sequencing was a job 6- job 18- job 2- job 22- job 5- job 10- job 19- job 16- job 12- job 1- job 23- job 17- job 13, and then with neighborhood search , its sequencing was a job 6- job 18- job 2- job 22- job 5- job 10- job 19- job 12- job 16- job 1- job 17- job 23- job 13, they had 147,13 hours for mean flow time. Lowering of mean flow time between existing conditon with two method which used, on batch of 0,20 x 914 mm was a 57 percent and then for 0,25 x 914 mm, was a 19 percent.

Abstract

Business strategy is indispensable to company become more active and sensitive for future threats. For external factor, environmental uncertainty need to be considered for improving their strategy and from internal factor is performance. This research will discuss the linkage among business strategy with uncertainty and performance in the field of freight forwarder Indonesia and logistic by financial and non-financial. The required data are questionnaire survey and using the data from some companies to analyze with approach of porter strategy (Russell T. Westcott et al. n.d.), before testing analysis, factor score of questioner will be calculated first with regresion after that, ANOVA result will be checked whether linkaged or not. Methods: The data sources in this study used primary and secondary data, which were then tested for validity and reliability, then a linear regression test was carried out to find out whether the value was significant or influential, whether there was a correlation or not, and ANOVA results were produced to determine whether there was a relationship or not. The results of the research number of respondents in this study were 100 respondents. Most of the the relationship between business strategy and environmental uncertainty (0.000), business strategy and financial performance (0.000), the relationship between environmental uncertainty and financial performance (0.000) and environmental uncertainty and non-financial performance (0.013).so that it can be concluded that there is a the significance value obtained is below 0.05 so that it is said to be valid, has influence and Ho is rejected which shows that there is a relationship between each variable.
