1.0 PRODUCT CHOSEN
Cucur Badak Shaping Machine is a machine that will produce shape of Cucur Badak
with a consistent amount of batter and filling. It is an adaptive design of dumpling
machine.
2.0 INTRODUCTION
Cucur Badak is traditional cakes that made of sweet potato dough and fill up with
spicy coconut filling, then deep fry till golden. The pictures of Cucur Badak is as
shown below:
Figure 1: Cucur Badak cakes
This traditional cakes is make manually by hand by small and medium-sized
enterprises (SMEs) like traders. After conducting a survey, it is found that while
making Cucur Badak, traders experience discomfort because of stickiness from
handling the ingredient by hand, slow production rate as well as inconsistency of the
cakes produced. Hence, in order to help solve these problems, a machine is design
based on the adaptation from the dumpling machine concept. After studying the
problem to finding solution, this proposal report will consists of conceptual design
which include problem definition, gathering information, concept generation and
evaluation of concept. Besides that, this proposal report will also include with the
purpose of the product chosen, the intended improvements in design and list of the
parts product.
2.0 Conceptual Design
The problem was that consumer demand for Cucur Badak necessitated the invention
of a more efficient process for kitchen dumpling production. The restaurant industry
desired a faster, more consistent means of making a dumpling on a commercial
magnitude as compared to the traditionally tedious and inconsistent hand-made
methods.
2.1 Problem Definition
Nowadays, food processing machine had become one of the fast growing industry in
the country. In order to design one of the food processing machine which is machine
that can produce “Cucur Badak” shapes that met or exceed the requirements of the
target audience, which is traders, a market survey were conducted at Shah Alam and
Klang. The purpose of doing survey is to find out the need of a customer before a
machine can be invented. After conducting a survey, most of the small medium-sized
enterprises (SMEs) are still using traditional method to make cakes and complaining
that it takes times and decrease the rate of production. As a result, with the present of
machine might help in increasing the production of the cakes. The customer needs a
machine that can produce cakes as much as possible in a day without need to worry of
getting hand dirty. Majority of the number are still using the traditional method to
make cakes which is by using hand and only small amount still using more advanced
technologies such as dumpling maker. Below are the data that show the amount of
trader agree and disagree to invent this machine.
Location Small Medium Enterprises (SME)
Shah Alam Agree – 15
Disagree – 2
Klang Agree – 9
Disagree – 3
Table 1: Data Survey to Invent Cucur Badak Machine
Description and Estimation of Market Size
After conducting a survey around Shah Alam and Klang, result shows that 29 small
medium enterprises (SME) that sell cakes. It was concluded the majority of cake
sellers agreed the invention of this machine will help them to increase their
production and save their time.
2.1.1 Competitive Products and Benchmarking
The competitive products and benchmarking were listed to find out the existing
specification and its advantages and disadvantages. This is to make a comparison and
as a guide to invent a new machine that will fulfill the criteria for the small and
medium-sized trader. Table below show few products that become competitive in

2.2 Gathering Information
ANKO’s Gyoza machine model HLT-960 was first invented in 1988, enabled mass
production instead of manual productions. However, HLT-960 was only suitable for
producing Chinese dumplings, as ANKO approaches the international market, we
have found that the machine could not satisfy similar products in the Western
countries, such as pierogi, tortellini, ravioli or empanadas. Therefore, ANKO's R&D
team invented the HLT-700 series, which are able to work with different dough
recipes and production is doubled in speed, not to mention the different product lines
it may create by changing dumpling molds.
Nowadays, in order to meet the array of market demands, ANKO keeps coming up
with solutions for our customers, various accessories and services are created to
enable mechanical productions of delicate products that was only able to be
hand-made, such as soup dumplings, hagao (Cantonese shrimp dumplings, calzone,
Jamaica patty and etc., which helps our clients increase product lines with less coast.
The new machines are suitable for factories or even independent restaurants.

3.0 Intended Improvement
Based on the net score from the Pugh chart, concept 6 is chosen as the product design.
This is due to its functionality that is better than other concept since it can operate
automatically which will increase the production rate. The material used to
manufacture this machine which is aluminum steel is stronger than plastic and have
long life span compared to the latter.
Besides that, the safety of the product is guaranteed which is designed to minimize
sharp edges and does not contain any sharp tools. It is easy to handle and need only
one person to operate it smoothly. The manufacturing process involved in this design
also is not complicated as others since the machine requires more assembly process
rather than fabrication process. This design is also marketable since it offers the
customer long run time and the production rate of this design is high which is eight
cakes per minute.
