AN ERGONOMIC APPROACH TO DESIGN HAND BLOCK TOOL FOR TEXTILE PRINTING HANDICRA...ijmech
Hand block textile printing is an important operation in small scale textile industries of India. Hand tool
mechanisms designed to reduce the various risk factors have rarely been studied. To make comfortable
handle design, musculoskeletal disorders prevalence investigation of workers associated with hand block
printing operation has been done. Data related to musculoskeletal discomfort were collected from 80
workers (age group 18-60 years) using questionnaire. Rapid upper limb assessment (RULA) technique was
applied for postural analysis. New hand block tool was designed using Autodesk Inventor 2014
(Educational Institute Version i.e. V5R12) and then analyzed with HyperMesh (Version 12.0) software.
Most of the workers reported that working with existing hand block tool is not comfortable. RULA
technique resulted as final score of arm and wrist for the working with existing hand block tool was found
out to be 5. After the modifications in hand block tool by using the ergonomics principles and
anthropometric data, RULA final score of arm and wrists for the working with developed hand block tool
was found out to be 3. The developed hand block tool has been revealed to be better than the existing one in
term of comfort level, it is improved 42.69% and production rate 29.62% increase as compared to the
existing hand block tool, it could offer an improved working facility and trim down unwanted workplace
injuries.
Standing for hours causes distress to the lower back of the body, to reduce such
kind of aches the chair-less chair came into existence. The chair-less chair also called
as portable chair is a wearable, ergonomic, mechanical, therapeutic device. The
ability to sit anywhere anytime is made possible by this wearable device. The chairless
chair can be worn as an exoskeleton on to our body and can walk normally when
not used. It is an equipment of convenience and comfort, because it acquires minimal
bearable weight. It is optimized by workers who stand and work for a very long time,
especially on conveyor belts and other industrial related works. It helps in reliving
back pain, limb ache, and tiredness and produces an increase in the efficiency of the
worker. This paper portraits the design of the prototype model which was made from
scrap, the mechanism of the portable chair, its applications. Future ideas and
challenges are also incorporated in this paper.

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

Design of Ergonomic Stool (Dingklik) for Batik Crafters
This research is conducted to reduce MSD found in previous research, by designing
ergonomically friendly stool to support batik crafters.
2. METHODOLOGY
The working position of mencanting (painting the wax) and reaching out for the wax is used to
calculate the optimal stool design. In order to make the design ergonomically friendly, a
anthomometric measurement is done in Kampung Laweyan, Solo, Central Java. The sample of
this research is 37 female batik crafters in five Small-Medium Enterprises in Kampung
Laweyan.
Currently batik crafters use a stool with out a backrest shown in Figure 2. From the
measurement the average stool used is 23 cm-high, 26 cm-wide and 22 cm-long. A research
found that a person sitting in a 20 cm-high stool for 16 minutes will have a higher level of
discomfort compared to the 10 cm and 15 cm-high stool. Thus, this average stool dimension for
batik crafting is indicated as one of the cause of musculoskeletal disorders faced by crafters.
This sitting position have big potential in rising the injury occurrence of WMSD (Work
Musculoskeletal Disorder) and fatigue on workers. All calculations in this research is using a
constant view distance of 30cm to the batik sheet hung on the gawangan and the a 30cm-high
of the stove.
Figure 2 Current batik stool used; 1: height, 2: width, 3: length
The questionnaire and direct observations done on this current situation, also strengthen the
assumption that the stool is not comfortable for an everyday use. Figure 3 shows that with the
current equipments most musculoskeletal disorders occurs on the right shoulder, upper back,
upper arm right, right forearm, buttocks, right foot and left foot. This result proves that there is
a work posture problem faced by batik crafters because of the current design of equipments, in
this case the stool.
To design an ergonomically friendly stool, an athopometric measurement was done. The
designing method of this stool is using a design for extreme principal. Design for extreme is
used to accommodate majority of people using the stool. This method uses the 95-percentile
and 5-percentile of the anthopometric data. The 5th and 95th percentile determined is assumed
to cover the entire population. The measurement needed to develop this design is as follows:
3. Anjani et al.

Figure 3 Frequency of musculoskeletal complaints on body parts
1.
Stool height
This measurement is using the 5-percentile anthopometric data, because it is assumed
that if the people in the lowest percentile could place there feet on the ground, so does
the people in the highest percentile. This mesurement is using the popliteal height of the
body.
2.
Stool length
The stool length is made using the anthopometric measurement of buttock popliteal
length. The data used is the 5-percentile data, to assure all users could lean back
optimally.
3.
Stool width
This dimension is made using the measurement of a 95-percentile worker. The stool
width is made to be able to support the hip of all users. Because of this the longgest hip
breath measurement is used. This measurement is given a 10% allowance to increase the
comfort of this stool.
4.
Backrest height
The backrest used is a medium-level backrest which could support the upper back and
shoulder. The height of a medium-level backrest is 60−80% of the human shoulder
height, which 80% is used in this design. To be able to support all users, the highest
percentile is used for this measurement.
5.
Stool and backrest angles
o
o
The tilt angle of the backrest is based on the optimal tilt level that is 100 −110
o
(Pheasant, 2003). The 100 tilt is used in this design to ensure the body position is more
stable especially for elderly people. The backrest that is tilt 100 degrees forces the neck
to make form a 30 cm viewing distance. This position will automatically make a change
in the neck-head angle 10 degrees downwards. For the seat itself, its the optimal angle
o
o
suggested is 5−10 (Pheasant, 2003). In this case the design uses 5 as the optimal angle

for the seat.
6.
Armrest height
The height armrest must support the lower side of the arm but is not allowed to injure
the elbow is sensitive. The backrest must have a 10 cm distance to the armrest to avoid
that injury (Pheasant, 2003). The height of the armrest itself uses the elbow sitting
height. This measurement will use the 5-percentile height so the people in this percentile
would not have to raise their arm to use this armrest.
The current design and improved design are analyzed using an ergonomic scale with Static
Strength Prediction (SSP), Lower Back Analysis (LBA), Ovako Working Analysis System
(OWAS) and Rapid Upper Limb Assessment (RULA) which is then evaluated using a Posture
Evaluation Index (PEI). The results of the improved design is then compared to the current
design to prove that it is ergonomically friendly. These ergonomic test is also done to prove the
proposed design reduces MSD effects on batik crafters.
3. RESULTS AND DISCUSSION
The anthopometric data was collected and tabulated in Table 1. This data is normally
distributed using 5%-level of significancy. A reability test was also done to validate the data.
From the test, it shows that the value of Cronbach’s Alpha is 0.893, which show that it is
reliable. A Kolmogorov–Smirnov statistic test was also done to show that the sample is drawn
from the reference distribution of anthopometric measurements.

This improved design (Figures 4 and 5) is proven to be more ergonomic friendly by the decrese
PEI score compared to the current situation. The current PEI score for the 5-percentile workers
using the current stool in mencanting is 2.166 for batik crafting with bent legs, which is slightly
lower than the position with straight legs with 2.202. The PEI score for the proposed design is
1.399. This result shows that it is more comfortable for 5-percentile workers to use the
improved design. This new design is also a good option for the 5-percentile workers in the
reaching wax activity. The current PEI score is 2.428 for the reaching wax position with
straight legs while for the bent legs position the PEI score is 2.247. The PEI score is much
lower for the proposed design which is 1.818.
This result is nearly the same for the 95-percentile workers. In mencanting the PEI result is
2.123 for the position with bent legs and 2.230 for the position with straight legs. The proposed
design’s PEI is much lower with 1.164 for the new design. This shows that it is also more
comfortable for the 95-percentile workers to use the proposed design for mencanting.
Currenlty, the PEI result for the reaching wax activity is 2.429 for workers who craft batik with
bent legs and 2.247 for workers who craft batik with straight legs. This PEI score could be
lowered if the new design is used, with the PEI score only 1.504. This proves that the new
design is also suitable for the 95-percentile workers.

CONCLUSION
• The recommended design for dingklik (batik stool) is 36 cm-high, 37.5 cm-long and 38
o
cm-wide, with a 5 angle from the horizontal surface. To this stool is also added a
o
backrest that is 46.7 cm-high that is tilt 100 . A 18.4 cm-high armrest is also added to
support the arm in crafting batik.
• The improved stool design is more ergonomically friendly for batik crafters. This is
proved with the decrease in PEI result for both the 5-percentile and 95-percentile.
