NEEDS
3.1 Find
Needs
As time goes, humans are pampered with new
inventions and technological advances. One such invention is the washing
machine. With it, we don’t need to put so much time and effort washing our
clothes, and instead use it to do other things. This machine also makes washing
a bunch of clothes an easy task, however, drying the clothes is another matter
entirely. Many people in the world rely on the sun rays to dry their clothes.
Even those who live in big cities have a hard time drying their clothes since
there’s not much space for it, and the air pollution discouraged people to hang
their clothes outside. These people then had no choice but to hang it inside,
which takes too much time.
To solve that problem, another machine was
invented, the clothes dryer. It does its job pretty nicely and is pretty much a
must-have machine in laundry services in the cities. However, the machine is
not without its flaws. Some of them includes: High energy cost. Dryers use a lot
of energy, for example, in the United States it is perhaps the largest
residential energy end use, which reached about 66 billion kWh per year, or
around 5.8% of all the residential electricity consumption in US. They’re also
not all efficient in removing water. Most conventional dryers are about 50-70%
efficient at removing water. Some citizens also want to keep one themselves in
their houses, but there’s also different preferences regarding its size and
practicality.
In short, the existing product
hasn’t been able to answer the needs of consumers yet, which is marked by
complaints and problems regarding the performance efficiency, energy cost,
practicality, capacities, etc. We also tried to make it environmentally
friendly and any other innovations that will suit the various needs of the
consumers. Therefore, before designing the product "Practical Clothes
Dryer", we do a survey to identify the needs and desires of consumers.
3.2 Obtaining
Consumer’s Opinion
The survey methods are done by direct
interviews and spreading questionnaire. Interviews conducted directly to our
target market or customer, housewives and people who worked in a laundry
services, basically those that will want to use a clothes dryer. Though we also
included students who washed their clothes by themselves. The results of the
survey are considered to represent the consumer needs of clothes dryer. The
survey on "Practical Clothes Dryer" will be shown based on the
questions in the consumer survey
3.3 Consumer
Data Result
Survey to consumers mostly done by spreading
the questionnaires to the respondents, while others were done by direct
interview (interview). The more respondents participate, the better it
represents the needs of consumers who want a clothes dryer. Here are the
results of the survey that was conducted to 111 respondents:
- How often they wash their clothes
Based on survey results, 41% of respondents washed their clothes every
day, 35% washed theirs once a week, 17% washed theirs twice a week and 7%
choose other option. It is clear in figure 1 that most, almost half of the
respondents washed their clothes every day, with those who washed theirs once a
week not too far behind. This is because the survey was conducted in the
Faculty of Engineering, University of Indonesia around so it can be seen that
most of the respondents are students and employees. For the topic of
"Clothes dryers" the target respondents should be people who wash
their clothes in large quantity or often wash them. So the results of the
survey conducted on respondents suits our target consumer and it shows that
both need to be considered.
| Figure 3.1 Percentage of How Often the Repondents Wash Their Clothes |
- Types of Clothes used
Based on survey results, 28% of respondents use T-shirts, 23% of
respondents use Shirts, 7% of respondents use Suits, 0% of respondents use
Coats, 1% of respondents use Kebaya, 2% of respondents use Gowns, 30% of
respondents use Pants, and 8% of respondents use Short Pants. This survey is to
know what kind of clothes that they usually wear, so we can adjust to it. The
survey shows that most respondents wears T-shirts, Shirts, and Pants. Meaning
the product will need to be in a considerable size. This is expected since most
of them are university students and employees.
| Figure 3.2 Percentage the Type of Clothes Used |
- Clothes Material
Data result showed that the material of the clothes are 1% from
Sutera, 29% from Jeans, 4% from Wool, 51% from Cotton, 15% from Bahan. With
Cotton being the most used materials, it shouldn’t need to much time to dry it,
but as shown in Figure 2., that of the survey results, one of the majority of
respondents wears pants which are most likely made from cotton. So clothes
dryer that we want to make must be at least excellent in processing or drying
cotton. Clothes dryer will be great if it can be dry all of type that metioned.
| Figure 3.3 Percentage of Clothes Material |
- How many use washing machine
The result showed that 50% use it, and 50% don’t. Based on survey
results, we found out that most of them use washing machine. So, they’re likely
to wash clothes in high quantity.
| Figure 3.4 Percentages of people who use washing machine |
- What time do they wash their clothes
Based on survey results, 61% of respondents wash them in the morning,
11% in the afternoon, and 28% on the evening/night. Apparently, many
respondents washed theirs in the night, where there’s no heat to dry them.

- The place to hang the laundry
Based on survey results, 56% of respondents said they usually hang
their laundries indoor and 44% other
said they hang laundries outdoor. The
percentage is near each other, eventough the respondents that hang laundries indoor
are a little much than outdoor. We can conclude that many people are interested
or habitually dried their laundries indoor, so maybe they intereseted in
clothes dryer that usually operated indoor.

their clothes, and the minority, 13% respondents are not depend on it. Majority
of the respondent’s answer said they depend of sun in order to dry their

when this situation come, hopefully clothes dryer can solve the problem because
it doesn’t depend on sun.

in one place when their laundries still wet or undried, 61% will spread out in
the sun indoor, 24% will dry their clothes indoor, and 14% other respondents do

in order to dry their clothes.
Based on survey results, 27% of respondents have
or use a clothes dryer and the least majority of respondents, 73% of
respondents said the don’t have or use a clothes dryer. This result said enough

idea about clothes dryer, 19% answer clothes dryer as an expensive stuff, 71%
