Summary: The common problems in planting rice are weeds and snails, which affect the growth and damage the rice crops in the paddy field. The study aimed to develop a Paddy Weeder with Snail Remover Attachment to address the problem of snail pests in the rice paddy fields. It aimed to remove the snail pests from rice paddy field plantations, subsequently reducing the damage they cause to the crops. It comprises a regular paddy weeder connected to a chain and sprocket mechanism. The snail remover claw is attached to the second sprocket with a 1:2.5 ratio of gear. The prototype also has a snail remover claw mechanism, which takes the snail and drops it into a detachable container. It also has an angled handle and is measured to be the perfect height for farmers to push. The prototype tests involving a paddy field with different aged rice plants 3, 10, and 21 days after transplanting. The tests measured the number of snails taken out of the field, and the number of weeds removed from the paddy field and evaluated the damage it caused to the crops while running. For the weeding efficiency that was based from AMTEC, the overall result was 100% in every pass for the crops planted in 3, 10, and 21 days. In 21 days, the highest percentage of damage result was 8.16%, which exceeds the standard percentage of damage of AMTEC. The 10-day-old rice plant was the stage that fits the prototype to remove golden apple snails. It has an overall snail collection accuracy of 90.56%, with the highest accuracy among the three stages. The overall evaluation result was 4.40, which has a descriptive meaning of very good in terms of ensuring adherence to safety standards and the intended functionalities of the system.

The common problems in planting rice are weeds and snails, which affect the growth and
damage the rice crops in the paddy field. The study aimed to develop a Paddy Weeder with
Snail Remover Attachment to address the problem of snail pests in the rice paddy fields. It
aimed to remove the snail pests from rice paddy field plantations, subsequently reducing
the damage they cause to the crops. It comprises a regular paddy weeder connected to a
chain and sprocket mechanism. The snail remover claw is attached to the second sprocket
with a 1:2.5 ratio of gear. The prototype also has a snail remover claw mechanism, which
takes the snail and drops it into a detachable container. It also has an angled handle and is
measured to be the perfect height for farmers to push. The prototype tests involving a paddy
field with different aged rice plants 3, 10, and 21 days after transplanting. The tests
measured the number of snails taken out of the field, and the number of weeds removed
from the paddy field and evaluated the damage it caused to the crops while running. For
the weeding efficiency that was based from AMTEC, the overall result was 100% in every
pass for the crops planted in 3, 10, and 21 days. In 21 days, the highest percentage of
damage result was 8.16%, which exceeds the standard percentage of damage of AMTEC.
The 10-day-old rice plant was the stage that fits the prototype to remove golden apple
snails. It has an overall snail collection accuracy of 90.56%, with the highest accuracy
among the three stages. The overall evaluation result was 4.40, which has a descriptive
meaning of very good in terms of ensuring adherence to safety standards and the intended
functionalities of the system.
