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