| Summary: | System of rice intensifications (SRI) was practiced by community in Lembah Organik
Lentang, Kampung Lentang since 2010. Throughout the years, the paddy plots began to
grow in number. Since most of the SRI practices needed to be done manually especially
planting the seedlings and using conventional tools to kill weeds and loaming the soil, the
demand of machinery was inevitable. This is due to time consumed and numbers of
manpower needed to carry out the task. For example, weeding process need to be done 4
times for one season. A new chassis that is able to support mechanical weeder and
transplanter for SRI was developed. This project was designed to support SRI practices
among Malaysian farmers. Product design specifications were gained from rice farmers
situated at Kampung Lentang, Belantek, Kedah. Several concepts were generated and the
best was choosen for further development and analysis. New chasiss was developed to
replace the current agriculture tractor. The chassis was fit with small petrol engine and one
main wheel. It was designed to pull SRI weeder and transplanter mechanism. The weeder
mechanism was designed to loam three rows at once and able to be use for weeding process
up to 40 days of age. Finite element analysis software was used to identify potential failures
and subsequent rectification of the problem at the design stage. Some calculation was done
to determine force and torque that may act on design. Steel was chosen as material to
reduce fabrication cost. Stainless steel and aluminum were also initially considered as
suitable material for the design but was not chosen due to the cost is high. For the rice
transplanter, the transplanting mechanism uses linkage to drop rice seedlings on top of the
soil. This fits the SRI practices for transplanting the young seedling. It is not just able to
plant one seedling at one location but also plant the seedlings without removing it from
nursery soil, thus, eliminate possibilities to injure the seedlings. Motion analysis was done
to analyze the linkage movement. Finite element analysis also was done to determine
maximum stress for each linkage part. Two of the designed products were built into
prototype which are SRI Chassis and SRI Weeder and tested in actual working environment
at paddy field. The field trial shows SRI Weeder was able to reduce manpower by 67%,
working time by 42% and save 60% of overall operating cost |
