Abstract PT. Indocement Citeureup , West Java, Indonesia is the big cement factory in single location, 10 plants, 14,4 million tons capacity, has been ISO 14001 Certificate, which indicated the management commitment in managing impact of cement manufacturing on the environment. The plant 11 is the biggest capacity with its great potential increase were decided to various support aspect. The management decided to increase the production performance using various engineer supports Plant 11 by Optimizing Finish Mill area, And QCC "Young On Top" team initiated the theme “Increase Finish Mill Production Capacity In Cement Production Process Finish Mill 11A”.

ICQCC 2015 Changwon, Korea By PDCA-approach methodology, consist of : 1. Analyze the recent condition and future potential 2. Stratification the issue 3. Analyze and find root causes 4. Planning and actualization the innovation solution especially for : A. Raw material process B. Attractive main process C. Up-graded the finish mill process After measure and check the result QCC "Young On Top" has succeed to increase production line increase 42 ton/hr ( from168 ton/hour to 210 ton/hr). The innovation activities could be identified from various aspect such us : - Dam Ring Reengineered - Purging time system calculation modified - New Installment of Bag filter membrane - New Upgrade operation skill in finish-mill operator There are 2 type of impact resulted : 1. Finish mill capacity increase to 210 ton per hour 2. Cost saving from this improvement about $ 29.525.935.29 per-year. In order to defend that capacity, we implementation maintenance SOP. For next improvement, we would be take theme about power consumption at finish mill area. To maintain our achievement, we established implemented the SOP. The next step has to be done to evaluate the results and take necessary action plans

ICQCC 2015 Changwon, Korea Step 1: Determining Theme and Title (Initial Goals) – Period WW III January until II February 2013 1.A. Determining the Theme 1.A.1 Identified the Priority Problem The Management is constantly boost the improvement of QMS implementation, in order to achieve the excellent process and best products, in accordance with customer requirement and satisfaction. This Improvement Project based on the SWOT analysis as follow :
SWOT Analysis PT. Indocement Tunggal Prakarsa, Collected by Januar
According to the SWOT analysis, the Plant-11 Manager decided to execute the S-O Strategy as an improvement project in his authority area, so he decided to build the QCC Young On Top as the project executor.
QCC young on top had discussion to determine project to improve production plant P11. We collect from manager report such as the key performance report yearly : 4

ICQCC 2015 Changwon, Korea Key Performance Indicator Evaluation Result and Absolute Target Score, Collected by Rommy
Target Score : 100 From key performance report and discussion with Mr Siswandi as Manager Plant 11, QCC young on top decide to improve Productivity and efficiency esspecially on Capacity fulfillment rate, because this parameter shown that actual capacity is the lowest performance and it has relation with S-O strategy so this parameter must be improved. This is project one sheet that intended for QCC Young On Top :

ICQCC 2015 Changwon, Korea 1.A.2. Making Conclusion and Formulating the Theme
a)
From the SWOT Analysis, Plant Manager very concern about the S-O Strategy and would like to make it became an improvement project
b)
On the other hand, the KPM evaluate result showing that performance of productivity and efficiency should be improved
c)
Based on the above matters, the Plant-11 Manager decide to build the improvement team.
Then the theme of this project is : " Improving the Performance of Plant 11 – Citeureup Factory"
1.B. Determining the Title IInitial Goals) 1.B.1 Analyzing the Current Situation Data Sheet : Capacity and Actual of Production Sections, Collected by Ricko
Data Sheet : Capacity and Actual of Production Finish Mill Units, Collected by Ricko
1.B.2 Making Conclusion and Deciding The Target (Initial Goals)
Observed the data of comparison between capacity and actual of production section, we recognized that a biggest lack of capasity was in the Finish Mill production Section
Looked at the comparison between Finish Mill units, we knew that the Finish Mill 11-A has the biggest lack of capacity.
