Utilization of Pine Leaves as a Botanical Pesticide in Nagari Tanjung Haro Sikabu-Kabu Padang Panjang, Lima Puluh Kota Regency"

Abstract

The use of synthetic pesticides is still the main method used by farmers to control pests in horticultural crops, including aphids. However, continuous use of these pesticides may cause negative impacts on the environment and human health. In Nagari Tanjung Haro Sikabu-kabu Padang Panjang, pine leaves (Pinus merkusii) are available in large quantities but are generally left unused as forest litter. This community service activity aimed to improve the knowledge and skills of local farmers in utilizing pine leaves as a botanical pesticide for aphid control in horticultural crops. The activity was conducted from 14 January to 18 February 2026 through site surveys, socialization, training on botanical pesticide preparation, field application, and monitoring. The results showed that participants were able to understand and independently practice the preparation of pine leaf botanical pesticides. The application of the pesticide was also able to reduce aphid populations on horticultural crops. This effectiveness is thought to be related to the presence of active compounds such as terpenoids, flavonoids, saponins, and tannins found in pine leaves. The use of pine leaves as a botanical pesticide can be considered an environmentally friendly alternative for pest management while also increasing the utilization of locally available natural resources.
