ABSTRACT
From the observation, people still used the traditional method to make laksa, which is take a lot of
time and energy. ‘Laksa’ Press Machine design is focusing on increasing the volume of laksa. This
machine is developed by using of electro pneumatics system that will increase the speed of the
production process and easy to operate. Also, to full fill the demand from industrial area, especially in
the manufacturing sector either in small or medium sized industries. In addition, it requires one person
to operate the machine. Furthermore it does not require very skilled labour to operate the machine.
From the finding this machine can produce more volume compare with traditional method. Within 61
seconds it can produce 1320 grams of laksa meanwhile with traditional method only 380 grams in 44
seconds.
Keywords: Development, Laksa Press Machine, prototype
1.0 INTRODUCTION
Currently Malaysian government is focuses on the industrial development of small and medium
enterprises (SMEs) in rural areas as a medium that can contribute to the national income. To answer
the call, the government is encourage people to designed a machine based food production can help
entrepreneurs and consumers. Therefore, we are focusing on making ‘laksa’ since ‘laksa’ is one of
national favorite food. ‘Laksa’ is a thick rice noodle a popular spicy noodle soup from the Peranakan
culture, which is a merger of Chinese and Malay elements found in Indonesia, Malaysia and
Singapore. The origin of the name ‘laksa’ is unclear. One theory traces it back to Hindi/Persian
lakhshah, referring to a type of vermicelli, which in turn may be derived from the Sanskrit lakshas
meaning "one hundred thousand" (lakh). Nowadays, the method of making ‘laksa’ is using traditional
ways. In addition this method also takes a relatively long time to produce large quantities and
manpower. ‘Laksa’ Press Machine is a machine designed to produce ‘laksa’ automatically more
efficient and systematic. Consumer is prefers to make their owned ‘laksa’. If consumer bought ‘laksa’
in stores the formed of laksa is hard and dry. Consumers had to soak the dry laksa into a hot water
until it is fluffy. Furthermore it contains chemicals or preservatives, intended to prolong the durability
or expiration date. A homemade ‘laksa’ is better in quality, hygiene and assurance of no chemical
compounds that can affect the health of consumers in the long run.
As a result, the objective for this project is to produce a ‘laksa’ press machine that adheres to the
following criteria:
i) A machine driven by a electro pneumatic system.
ii) A small and simple design, easy to control and easy to organized.
iii) A machine that has various forms of mould into a desired shape
This project will focus on pneumatic system for the operation of the machine in order to speed up the
timing for pressing the ‘laksa’ ingredient. The machine has various forms of mould into desired shape.

The main mould is made by aluminium since it not rusty and cutting blade is using stainless steel.
Main body is made by mild steel and L shape mild steel.
2.0 REVIEW OF LAKSA PRESS MACHINE
The research of this project is based as the flow chart below.
Research types of laksa and their characteristics.
Research types of cutting machines available in the market
Identify the workers problem which occurs while handling laksa
Literature review for the machines
Study for the advantages and disadvantages of the cutting machines in the
market
Design the concept of the electro pneumatic of laksa pressing machine
Testing laksa pressing machine

2.1 Traditional Method
There are various types of blades for cutting the end of laksa in the market.
a) Copper circular blade
Advantages: - The machine is easy to use, mechanically
Weaknesses: - manual, no safety features, longer processing time, using a lot of man power,

b ) Aluminium Press Blade
Advantages: - The machine is easy to used, various type of shape and light.
Weaknesses: - manual, no holder, longer processing time, using a lot of man power,

3.0 PROJECT DEVELOPMENT (METHODS)
3.1 Design Concept
This electro pneumatic laksa press machine is driven by pneumatic system and the relay is the
cascade type of circuit because it's easier to arrange the pneumatic components. It is a combination
of 4 Cylinder Two Action (DAC).

3.2 Material selection
In designing "Laksa Press Machines", there are several material to select depends on the purpose
and usefulness of a product to be produced. Usually the raw material selected has to be suitable with
the project purposes. Material selection is based on the strength and resilience of the materials in the
production of products. Among the raw materials used are stainless steel, aluminum,acrylic resins,
mild steel, plywood and others. Others component considered such as cutting blades, the position of
the two actions cylinder, valve being used and the pneumatic system and air compressor.
4.0 ANALYSIS (VALUE/COST/BENEFITS, FORECAST)
Design is also a process of rational decision-making and trying to choose the best solution in
accordance with the scope required. In any design, problems are viewed from different aspects and
solutions made in various ways such as using mathematical analysis, the experience of the existing
dam and problem solving using the results of research or experimental design. As a conclusion, the
design of the products below are based from a few things to consider, such as, product is easy to
install, the product is easy to re-open, the product credibility easily taken care of and maintained and
the product has the characteristics of a good security.

4.1 Cost and performance
The cost for fabricate this machine is about RM675.50, which included cost for material RM 557.00,
cost for painting and labour cost is RM90.50 and overhead cost is about RM28.00. Although the cost
is of pneumatic piston is quite high but the ability to get consistency of the thickness and the length of
the rice noodles is achieved.
4.2 Benefits
Using pneumatics for operating the machine will increase the cost but in other hand, the quality and
quantity of the products would be uniform in the sized and thickness. The production could be
maintained as required and does not affect the production although shortest of labours.
4.3 Test run
During the test run, the machine runs smoothly with the correct ingredient mixer of rice noodle. The
problems occur when mixer of the rice noodle being press, its flow is in lengthwise until it reached the
table below. The product is overlapping each other since the absence of a rotating table to
accumulate the product.
5.0 CONCLUSIONS
As a conclusion this product has been completed successfully due to its schedule. By using this
machine in the small and medium industries, we hope that more benefit and would increase the
production itself. Although the price is expensive but the time taken for completing 1320 grams is only
61 seconds compare 44 seconds with 380 grams. The selection of using electro pneumatics hopefully
will reduce the cost of labours. All sectors will get the benefits as no skilled workers are needed to
operate the machine therefore more research could be made to upgrade the quality of productions.
