ABSTRACT
PT Argo Pantes Tbk. is one of the companies Manufacture in Indonesia are engaged in
textile industry, to type of thread Carded 32 happened extravagance that have been
identified successfully by using value stream mapping project with the approach to the
point DMAIC DMAIC. Any, with a current state, is performed through Civil Measure with
measuring percentage non-value added, and takt time, Analyze by using analysis Fishbone
and kaizen blitz, receiving complain with future state mapping, Control to control the
process of production that has been fixed. That have been identified successfully waste is
wasting analysis current stream. mapping leadtime production was 19.46 percentage day,
with non-value added to 97 percent and in future state mapping by applying the attraction
supermarket and use the merger process causes the material can be organised and
drastically reduced waste preparation, with experienced leadtime production of 0.41
percentage day, and non-value added up to 44 percent.

ABSTRACT
PT Argo Pantes Tbk. is one of the manufacturing company in Indonesia which is engaged in
the textile Industries, for this type of yarn carded 32 to avoid waste were identified by using
value stream mapping with DMAIC approach. At this stage of DMAIC, Any by making
current state, is performed through Civil Measure by measuring the percentage of non-value
added, and takt time, Analyze using the Fishbone analysis and kaizen blitz, receiving
complain the future state mapping, the Control to control the production process has been
improved. Waste that has been identified is a waste edged higher. stream mapping analysis
of current production lead time is 19.46 days, with a percentage of non-value added
amounted to 97 percent and in future state mapping by implementing the use supermarket
pull systems and the inc. process causes the material flow can't lead time at 0:41 the day,
and the percentage of non-value added to 44 percent.

INTRODUCTION
PT Argo Pantes Tbk. is one of the manufacturers in Indonesia are engaged in textile
industry. This Company mengahsilkan various kinds of thread and cloth. To type of thread
Carded-32 (Cd-32) is a kind of spider thread, which is very many of his request, but if seen
from the efficiency especially in time for the process, Inventory which occurred in every
process. Companies are still have to work hard to improve their production process system
that they should apply. For that lean was present as the concept defining waste, through
the Human Resources who have at this stage DMAIC so it can be more detailed stage any
(DMAIC) will be done value stream mapping to know waste that happened. Continued with
is performed through civil measure to calculate Takt time, and percentage non value added
that happened on our production processes, and analyze with the aim to get formula to
solve. In the final receiving complain to carry out the repair that has been analyzed, and
Control to evaluate companies for the better and make sure that there is an increase of the
process.
Formulation of problems:
a. How

c. Know wasting (Waste) dominant in the process of production thread The Cd-32
d. Providing on to the company to improve reduce Waste and activities high-value-added
products (Non-Value Added Activity).
Boundary problem :
a. This research done on the floor Argo Pantes production at Pt Tbk, in part, and product
unit Spinning1 thread The Cd-32
b. Data that is required in this research is focused on time production process, and activity
production, which is used to identify extravagance, was not included in calculating the
cost.
c. Lean manufacturing researched Waste is the most dominant.
d. This research is focused on a Non-Value Added.
RESEARCH METHOD
Research methodology describes steps that will be run in this research. Research
methodology was made to execution process or it can be structured with good and can
achieve the goal that was established before. Objects or PT Argo Pantes Tbk producing
textiles from thread to the Treasury Department the cloth. Unit Spinning-1 produce thread

and adjusted by observation dilapanan
2. To Make formulation of problems
3. To Make the aim of the research
4. Assessment secondary data from a number of data request production in february 2015,
conversi chis, hours of work, number of flow of information machine, etc. And primary
data in the form time machine each time the transition process, material, time set up
machine, the number of inventories, the distance railway station.
5. After penumpulan data, and our data to be with the approach DMAIC, the data
consists of 5 stages, with levels any time we prepare cycle, WIP every process, and
make current stream mapping, stage is performed through Civil Measure menukur
time takt time, and measured non-value added in the current stream mappin, stage
Analysis to analyze fishbones, and make kaizen Blitz, stage receiving complain make
future Stream Mapping, The Control improved are constantly and document standard
practice.
6. Buyback results and analysis, after our data to be the result of temua- temua that is in
processing data so we must analysis
7. After we finished analyzing results so,we can give conclusion and suggestion.
RESULTS and DISCUSSION
Define Phase
1. Choose Family Product
To choose family products diperlukan analysis of production.
Table 1. Analysis of production
Picture 1. Pareto diagram
It follows Pareto diagram CD-32 have volume 59.7 percent of the total production.
Table 2.Analysis of The route Production
He has chosen family CD-32, CD-30 and CD-40, because it has a production, and half of
the total production, and has a production line for the same is selected product CD-32
to be investigated further.

Picture 3. Fishbone Analysis
After diruncingkan there are 3 dominant factor that causes long lead time production:
a. The accumulated business material maximum in every process especially in the
warehouse raw materials and packing
b. There is no production standard
c. The process is too much.
2. Making Kaizen Blitz
Using the methods Kaizen Blitz is expected to focus on what it must be improved so
that it is hoped that the application value stream mapping on the floor factory is to
remove the process is not value added products.
Picture 4. Kaizen Blitz On Current State Mapping
Improve Phase
An alternative to overcome the problem can be seen from the kaizen blitz in Picture
4 while The application improvements can be seen in Future State Mapping
Project. But on improvements that will be done to change Current State Mapping
to Future State Mapping are:
1. The merger Safety
To do the work this process must have the level characteristic work uniform, and
the output that period, so calculated that high production carding machine,
drawing, and ritter in fox so 1 process this was done by making process high
production carding machine, drawing ritter to 1 line for that required cooperation
between line spot high production carding machine, drawing and riter. The
merger safety would also be made in the Winding machine grant and packing,
and because this is the merging process to one, then we can take time Cycle Time
was the highest.
2. Continus Flow
The application Continus problem will be done to reduce the level preparation, in
roving because time Cycle Time, not much different with ring spinning and
therefore for creating this process will be done mainstream Continus Flow.
3. Use Supermarket
Supermarket in the proposal this improvement function as safety stock which
consists of 5 supermarket :
a. The first Supermarket are among the raw material, and blowing, this is done
distance warehouse materials to blowing that far enough, and not as
uncontrolled inventories in the area blowing.
b. Supermarket was in an area between blowing and CDR, because the interval
cycle time was very different, and the distance is far enough.
c. Supermarket and the third among CDR and Roving, this was because time
cycle time, far different.
d. Supermarket and the fourth between ring spinning and Winding machine
grant-pack.
e. The latest among Winding machine grant-pack and warehouse work so.
Shipping materials from the warehouse to blowing was changed to 4 hours
per day, or 0.16 to 0.03 CDR blowing to day, CDR to roving to 0.03 days, ring
spinning to Winding machine grant 0.03 days, and packing to the warehouse
work so 0.16 day, this was done in order to control production because continus
problem is not possible to be applied, so the application is hoped to be able to
supermarket WIP between process.

From Future State Mapping Project, it is known that, time Process Time is 635.12 minutes,
and time production fell to 0.41 Days, and because in the day he needs to change to minute,
according to the time Avalaible bpd by the 1215 minutes. The calculations for :

Analysis Inventory Every process (WIP)
The Current State of production of the thread Mapping in Cd-32 we can see that wip in
every process in number are varied and average industry is still too many when viewed
from the perspective lean manufacturing. Debt rescheduling that is not good is seen when
we see a daily production, when there are so many wip available process was still is
scheduled to start, this thing could be caused by wip is not generally known by planners
production.
Picture 8. The Number of wip in every process in current state mapping
Analysis of comparative total Production Lead Time
Based on the amount of time production lead time, so we could see the existence reduction
production lead time of 19.46 day to day 0.41, this was because among workstation with
each other there is no WIP .Production lead time is a total of every inventory that is in the
bloodstream value stream mapping in producing thread the CD-32.
Picture 9. Comparison production lead time
Analysis of Non-Value Added and Value added

CONCLUSION
a. Production lead time reduced from 19.46 day to day or go down as much as 0.41 19.05
days.
b. Percentage time Non-Value Added that was high in Current State Mapping project that
is 97 percent reduced to 44 percent in Future State Mapping
c. Waste Dominant of production of the thread which took place in CD-32 is Over edged
higher.
d. On the production process thread the CD-32 is wearing supermarkets in the process
that have cycle time, far different, and was some distance, this was done to controlling
production so, inventory every process can be avoided because they were in control by
wearing the supermarket.
