Mr.Samart Leethirananon was born on 8 May 1960 in Chinat Province. Raised by a family of sugarcane growers and grown up in a labor-intensive agricultural production environment, Mr.Samart has always appreciated the hardship of farmers, particularly those engaged in sugarcane cutting and loading the cane on trailers/trucks. Thus he was inspired, since very young, to help out these farmers.
By the time he became a competent mechanic, firstly through apprenticeship in a machine shop in Bangkok and then by working as a technician in agricultural machinery/equipment repair shop in his hometown, Mr.Samart was fully convinced that he could put his skills and knowledge to good use in the farm machinery/equipment sector and help mechanize the sugarcane industry.
With this vision he founded in 1996 a farm-machinery manufacturing company called Samart-Kaset-Yon Ltd., Part., which became the first Thai manufacturer of cane loaders (grabbers). The products were marketed under the SMKY brand. Soon after SMKY was established, labor shortage in the farming sector became widespread. Moreover cane burning (before harvesting) a common practice in Thailand and elsewhere that causes air pollution and global warming, has emerged as an increasingly critical issue that threatens the sustainability of sugar industry. Mechanization as a solution to these problems in cane farming thus constituted a compelling reason for SMKY to start developing cane harvesters. Although these machines can be imported from abroad, they are too expensive (even secondhand ones) and too large in capacity for local farmers who mostly own small land plots for sugar plantation. The difficulty in manipulating these large machines around the plantation not only makes the machines unpopular to workers, but also increases the operating costs and causes damage to the soil by compacting it. Furthermore, owners of imported machineries have to face the challenges of aftersales services, such as acquisition of spare parts that are not locally available. SMKY then started to develop cane-harvesting machines. However Mr.Samart soon realized that to make high quality, reliable and durable machines, R&D support is needed. Consequently, he invested heavily in R&D and high precision machinery. Seven years later, with the support of his son, Mr.Vitoon, SMKY became the first Thai company to export cane harvesters, with customers in Brazil, India, Indonesia and Cambodia.
To date SMKY has introduced two versions of cane harvesters: one with conveyor and one with basket. The former version cuts sugarcane into small billets and directly loads them on a truck. However, the repeated runs of heavily loaded trucks on the field tend to increase soil compaction. On the other hand, the latter version solves this problem by loading billets on a basket on the back of the harvester. When the basket is filled, it is picked up by a truck. In this way, this machine is able to move around hilly areas and small plots. However the operation can be time consuming. The latest version of SMKY harvester comes with a bigger basket and equipped with mechanisms for automatic cane loading to the truck, enabling farmers to work faster and reducing soil compaction.
By designing and manufacturing all parts locally (except the engine and hydraulic motor) with local knowhow, SMKY is able to produce brand new harvesters at a much lower cost than imported ones. Another important advantage is that almost all spare parts are available locally, and the farmers can often do the repair by themselves, hence reducing the maintenance costs significantly.

Nowadays, genomic technologies are considered the quintessential and
they have been widely adopted in numerous research fields. Dr.Somvong
Tragoonrung has been instrumental in defining genomics research since
before the field was recognized as a significant discipline in Thailand. In 2000,
he revolutionized scientific research here by founding the DNA Technology
Laboratory (DNA Tech) as the most successful service laboratory in Thailand
providing affordable technology for public agencies and more than 800 Thai
and foreign private companies. The services offered by DNA Tech have been
helpful in improving the quality of agricultural products, facilitating the export
of products and addressing several international trade law and barrier issues.
Two most important and sensitive diagnostic services for the country are the
determination of Jasmine rice purity and GMO testing for exporting food products
generating a strong impacts value over 50 billion baths. As the director of
Genomic Institute in 2006, BIOTEC, Dr.Somvong has developed various genomic
tools to facilitate genetic improvement of top national economic crops. His
expertise in next generation sequencing provides important genomic platform for
breeding perennial crops like oil palm, the highest potential oil and energy crop
for Thailand. He has successfully integrated the genomic and the plant tissue
culture technologies to generate new oil palm varieties that are suitable for Thai
climate and environment in merely seven years, compared to the traditional
oil palm breeding which typically takes 15-20 years. Delightfully, these newly
developed palm varieties are currently being distributed to plantation owners
across the country and the established technology has been transferred to
the private company in the South. Besides its remarkable contribution to crop
improvement, the DNA Technology laboratory and Genome Institute also holds
several international publications and patents

Jewel ry indust ry i s one of
Tha i lands th r i v ing economies .
Historically Thai goldsmiths are known for
their superior craftsmanship, patience,
jewelry designs and techniques. On the
international level, nowadays stringent
regulations, quality assurance processes,
fast turn-around time, standardized
manufacturing protocols and rising
raw material costs all have played
important roles in limiting Thailands
competitive edge over manufacturers
from other countries.
It is our research groups goal
to introduce cutting edge technology
and innovations to the industry to help
save manufacturing cost, to reduce
the wasteful usage of consumables,
and to decrease turn-around time
for new products. It is important to
put and maintain our country at the
forefront of jewelry manufacturing. As
Thailand has less and less dependency
on foreign technical supports in terms
of equipments, raw materials, alloys
and technical consultancy, we will be
creating our own equipment human
resources, our own technology and
our own manufacturing technology.
The two illustrated technologies are
from our recent development and
quests to revolutionize the ways one
could manufacture jewelry articles with
minimal time, limited raw materials
cost, and efficient use of energy.
AbstractThe first technology is based on a special alloy design combined with
improved soft silicone and rubber mold technology that allowed us to bypass
several manufacturing steps in jewelry manufacturing. No more wax injections,
no more wax tree creation, and no more lengthy burnout cycle are needed. We
proposed a new casting technique that allowed manufacturers to directly inject
liquid silver alloys directly into soft silicone or rubber mold instead of wax. This
one step injection process completely eliminates the need for investment which
could only be used for one time. The casting temperature is maintained at relatively
low level which implies minimal reactions between liquid metal alloy and the
mold wall. This reduces costs for subsequent surface finishing as less reactions
take place at the liquid-mold interface. Moreover, the alloys could be reused
for more casting runs before the metals need to be refined. For longer and more
massive production runs, metal molds could be used instead of silicone mold
to increase mold life. From the usual 4-7 days turn-around time for conventional
technique, our new technique offers a much faster alternative. The production
time is only limited by the time to create initial mold, and subsequent production
pieces could be obtained in minutes.
The second technology presented is based on a new class of material
known as bulk metallic glass. The material uniquely combines the ease of forming
with unrivaled mechanical properties. In our case, the 18 karat gold has the
hardness value of 350-420 Hv as compared to 60-140 Hv range for commercial
alloy formulation. Our research was aimed at two aspects: (1) to improve the
mechanical properties beyond the current values, and (2) to locate suitable
forming technique that is economical, mimicking that of thermoplastic forming.
To illustrate, the material was first made into pellets just like those plastic pellets
used in thermoplastic injection. Then these 18 karat amorphous pellets were
formed into different shapes and forms at below 200 degree Celsius, utilizing the
supercooled liquid region that only exists in this new class of metals. Imagine
molding pieces of jewelry like clay, stamping like plastic, and blowing like glass,
the opportunity is endless. We showed for example how to mold these 18
karat pellets with clothe iron, or how to heat up the metallic glass bars using
abrupt resistive heating technique prior to stamping. At room temperature, these
materials maintain their mechanical properties at about 3.5 to 4.5 times harder
and stiffer than their crystalline counterparts, yet the forming could be done at
much below their melting points. The first and the second materials revolution
already happened at the introductions of steels and plastics and now we have
the wonderful combination of mechanical properties (steels) and ease of forming-
ability (plastics). In the near future, this material could revolutionize the way the
industry would manufacture jewelry articles.
