Standardizing the result of improvement 7. Deciding further planning Plan : Real : REASONS OF CHOOSING THE THEME:. It is the main priority. The bagging machine experienced to loose much production time due to the of its plate conveyor. Bulk handling conveyor Vibrator Feeder PROBLEM AREA Bagging machine THE FLOW OF UREA BAGGING AND LOADING PROCESS Bin conveyor Traveling conveyor Sewing machine Bag handling conveyor Accumulator conveyor Short loading conveyor Number of meeting Warehouse Truck Train The process of urea bagging and loading from the bulk handling conveyor to warehouse, trucks, and train was in trouble due to the of bagging machine mainly in part of plate conveyor.

2 STEP I DECIDING THE THEME AND TITLE Period: February to,. DECIDING THE THEME.. Below is the Pareto diagram of bagging machine -L base on frequency, duration, financial lost. Period of January, data resource: daily report of bagging section taken by Suhanan Saputra and Moch. Maliki.

3 II. Ishikawa Diagram STEP II ANALYZING THE CAUSES Period February to 9, The Operator has less quality awareness The operator wished to finish the work as soon as possible The chain is broken The chain suspense is too high The arrangement of the chain suspense is not accurate The chain is out of track (derailed) The distance between sprocket is minimum MAN The machine operator worked hastily The arrangement of sprocket is incorrect 7 METHOD The plate is corrosive easily MATERIAL The thickness of plate is decreasing The strength of plate declining The plate is bent easily The chain movement is zigzag The chain is not in line with the plate The distance between the bolt of plate is different No standard distance between the bolts of plate MACHINE There is a lot of urea dust ENVIRONMENT The atmosphere at the area of bagging machine is corrosive The plate is out of chain The bolt of plate is broken The plate is bent The plate conveyor of bagging machine - LE is frequently The falling distance of packed urea is too high The distance of bag holder and the plate is mm The guide plate cannot muffle sudden energy of falling thing The gap between guide plate and plate is wide II. Nominal Group Technique (NGT) N o Dominant suspected factors AS SS MM RS DR Total Rank The operator has less quality awareness The plate is corrosive easily There is a lot of urea dust 7 The distance between the bag holder and plate is mm The gap between guide plate and the plate is wide 7 No standard distance between the bolts of plate The arrangement of sprocket is incorrect 7 7 The arrangement of chain suspense is not accurate Based on the NGT questionnaire of all the QCC members, it can be counted that the index of NGT is. The NGT table shows that there are five suspected factor which influence the of plate conveyor of bagging machine - LE ranked from to or respectively number,,, 7, and. NGT = ½ x + = + =. The arrangement of sprocket is incorrect.. No standard distance between the bolts of plate.. The gap between guide plate and the plate is wide.. The distance between the bag holder and plate is mm.. The arrangement of chain suspense is not accurate.

The gap of guide plate to sprocket is incorrect. of plate.. The suspense of plate (mm) r = ,99 r =.99, The distance of sprocket (mm) The distance of sprocket (mm) r r = = ,99 r r = =.9,9 The distance of of plate plate bolt (mm) bolt ( mm) r r = =.99,99 r r= =.997, The gap between guide plate and The gap between guide plate and plate plate (mm) (mm) Conclusion III.: The distance of sprocket greatly influences the of plate conveyor of bagging machine (negative correlation) Conclusion III. : The distance between plate bolt highly affects the of plate conveyor of bagging machine (negative correlation) Conclusion III. : The width of guide plate gap extremely influences the of plate conveyor of bagging machine (positive correlation) III.. The distance of bag holder III.. The arrangement of chains Is mm. suspense. r =.99 r,99 r =.99 r =,99 9 The The distance distance of bag of bag holder holder to plate to plate (mm) (mm) III.. Pie Chart of Suspected Dominant Causes 9 r =.99,99 r r =.9 =,9 7 The The distance distance of of chain chain bent bent from the from line the line position (mm) (mm) Conclusion III. : The distance of bag holder to mm affects the the of plate conveyor of bagging machine (positive correlation) Conclusion III. : The arrangement of chain suspense greatly influences the of plate conveyor of bagging machine (positive correlation) r =.99 (7.7 ). r =.99 (7. ). 9.9%.% /.7% r =.99 (7. ) 9.99% 9.97% r = -.99 (7.97 ) r = -.99 (7.9 ) Based on the experiment result and pie chart, the dominant causes of the of plate conveyor of bagging machine -LE are as follows:. The arrangement of sprocket is incorrect. No standard distance between the bolts of plate. The gap between guide plate and the plate is wide. The distance between the bag holder and plate is mm. The arrangement of chain suspense is not accurate

5 N o Dominant factor The arrangement of sprocket is incorrect No standard distance of plate bolt The gap between the guide plate and the plate is wide The distance between bag holder and the plate is mm The arrangemen t of chain suspense is not accurate STEP IV THE PLANNING AND IMPLEMENTATION OF IMPROVEMENT Period May to, Why What Where When Who How Straighten the position of chain to sprocket To avoid the suspense of plate and out of track due to the chain pull or pressure To avoid the suspense of plate due to the strike of kg packed urea To avoid hard strike of packed urea to the plate To avoid the of plate and the chain due to the tight or loose chain To arrange the distance between sprocket to 9 9 mm Create the distance of plate bolt to 7 mm Create a gap between guide plate and the plate to mm Create the distance between bag holder and the plate to 9 mm Create the distance of chain straight to 9 mm The area of bagging machine -LE in bagging and loading section May to, Suhanan, and Rosadi Asep S, and Dhohri Asep S, and Suhanan Dhohri, and Suhanan Asep S, and Dhohri. Release all bolt of key sprocket.. Straighten one of the sprockets to the track and fasten the key bolt.. Arrange other sprockets to the distance of 9 9 mm.. Take a plate ; draw the diameter of plate.. Draw two points of the plate with the distance of 7 mm.. Drill a hole of mm on both points of the plate with a drill tool.. Refine the hole.. Lift the guide plate by using jack bolt.. Use feeler gauge to decide a gap between guide plate and the plate to mm.. Lock the position of guide plate by welding it to the supportive iron.. Hang the bagging machine by using sling and chain block.. Release the foundation bolt of bagging machine.. Cut the base plate to mm and make new base plate.. Haul down the bagging machine, measure the distance of bag holder and the plate, then make a distance to 9 mm.. Tighten the foundation bolt.. Press the chain and measure stretch by using moving calipers.. If it is wider than mm, tighten the chain by pulling out both sprockets.. Re-measure the distance of its stretch and create the distance to 9 mm. How much % % % % %
