Abstract

PT X is a company which produces vegetable oil with copra and Crude Palm Oil (CPO) as the raw material. PT X wants to supply international company, such as Kraft Foods. Kraft Foods has several regulations for prospective suppliers and of them is HACCP documentation. The design of HACCP system in this thesis is done for RBD (Refined Bleached Deodorized) CNO (Coconut Oil), Olein, and Stearin which produced at Plant 2 PT X. The first Critical Control Point (CCP) are sack fiber, sponge, and metal at the output filtering process. The controlling of the first CCP is done by monitoring the pressure gauge when the filling process is done. The second CCP are tee cable, animal pest, and cloud filter fiber at stearin strainer. This CCP is controlled by stearin strainer cleaning before and after the production process. There are several differences between the HACCP system at PT X and Kraft Foods, such as the quality standard, risk analysis, and documentation format. Based on the analysis that has been done, the percentage of processes belong to Prerequisite Program for RBD CNO are 32,26%; RBD Olein are 35,48%; and RBD Stearin are 33,33%. The percentage of processes belong to Critical Control Point for RBD CNO and Olein are 3,23%; RBD Stearin are 3,33%.

Abstract

To control the production quality in terms of product weight, PT. X needs a standardization in production process. The weight standardization will help ease stocking process for both the company and the distributor. This research is used on the hollow product with chain type A with gold levels of 70%. Some of the products weight are not constant due to the variation of shrinkage percentage in every production process. The solution for this problem is to reduce the variation of shrinkage percentage levels in every production process using PDCA method. The improvement results obtained from PDCA method is shown on hammering, hollowing, and bombing process. On hammering process, a decrease in the shrinkage percentage variation is done by controlling the wire’s thick shrinkage percentage 15%-20% for a 5% shrinkage percentage. The percentage of necklace on hollowing process can’t be controlled, as a result an improvement is needed by giving an accurate range percentage standard, 49%-52% for chain A with gold levels of 70%. The weight shrinkage percentage in bombing process is depending on the size of small, medium, and large chain respectively 4%-5%, 5%-6%, 6%-7%.

Abstract

The problem faced by XYZ Department in PT. X is related to data processing of XYZ Program. Time to execute six processes, such as lookup data and data adjustment are 160,41 minutes or about 2,5 hours. Rate of data validation that should use historical default are still low where the data in the 19th week which used as samples, there are more than 5000 data or about 5% of the anomalous data. The root cause of these two problems are the absence of automation program for data processing and no historical default for certain mechanisms. XYZ Department also requires a dashboard that can display the entire data, from national level to store. Automation program and dashboard are created to accomplish problems and needs of the company. Time needs to do the six processes with the automation program becomes 9.2 minutes. The effort from the operator who processes the data is also reduced because they just copy data on the template that has been provided, enter the week to be processed, and click the required button. Anomalous data on mechanisms that should use historical defaults have also been facilitated with Adjustment buttons where there is no anomalous data after this process is executed. Dashboard can also facilitate in analyzing data about the achievement or performance of the existing mechanisms and see whether there is an enhancement in the percentage of business grow in accordance with the company objectives.
