Abstract

PT X is a multinational company with many export and import activities for expanding their markets. PT X has a problem in import activities regarding payment for import duty’s penalty and tax’s penalty. PT X never know the root causes that cause a penalty on import duty and that’s why the right actions to solve the problems is never be done. PT. X propose a new method to know the root cause of the problem which called Reconcile. Reconcile method still have so many technical problems that will make the result won’t be accurate. Risk Management method is used to analyze the risk that happened during the COO issuance. Risks that have been analyzed will be sorted based on its handling priority using Risk Matrix method.

Abstract

PT.X is a company that produces consumer goods located at Rungkut. One of the departments at PT.X is engineering services department. Part of the tasks that this department aware are monitoring energy usage, carbon dioxide emission, and water usage for each year on each factory. There factories are monitored, that is Sukorejo factory, Karawang factory, and SKT factory. The department will receive data of energy, carbon dioxide emission, and water usage performance in the forms of excel template files. The existed problems at the beginning of this project were, for each department they had their templates for recording the data. It was challenging to evaluate the energy usage, carbon dioxide emission, and water usage, and to compare them “apple to apple”. Another problem faced by the department was knowing the sources of higher usage in energy, carbon dioxide emission, and water. Therefore, to solve those problems, in this project we propose a new template that covers all three factories data set. The new template is standardized for all departments level. Additionally, it is constructed using Microsoft excel with macro feature, so that it will be easier for a user to input and evaluate data. The template has two functions, that is for inputting data, and reporting the summary statistics. The summary statistics is reporting in a form of a dashboard.  It is well known that a dashborad can help the management to analyze the data, and to make the performance comparison across all departments level.

Abstract

One of the most common problem happened at PT. Charoen Pok­phand Indonesia is the failure in feed collection systems on pellet machine. This failure should be minimized since it creates huge loss in terms of downtime in the working process of the pellet machine. The failure is analysed using 5 Why’s and Failure Mode Effect Analysis (FMEA) to find the source of the failure. From the analysis, the proposed improvements are to change the parts of feed collection systems and to create a guidance in maintaining and monitoring feed collection systems. The failure in feed collection systems did not happen anymore after the proposal is implemented with the saving costs of manufacturing as Rp472.500.000,00 per month.

Abstract

PT. XYZ is a company that produces shoe. This study is subjected to reduce expired chemicals because it was keep too long in finishing line and to design a safer and ergonomic trolley. The amount of expired chemical due to there is no standard scheduled for distributors to distribute chemical in the finishing line so that many chemicals are stored in line and finally expired. The trolley is now considered less secure because there is no buffer on the front of the trolley thus allowing the jerry can to fall. Chemical distribution schedule will be made based on work measurement method. The result of this work measurement is that chemicals will be distributed for an hour so that distributors will distribute chemicals seven times in one work shift. The number of chemicals allowed to be in the finishing line is also limited by the need for chemical for one hour so that no chemical is wasted due to expired. The new trolley will be made based on anthropometry data to make it more comfortable and safe to use.
