Abstract

Aphids (Aphis gossypii) are a potential pest on broccoli plants (Brassica oleracea). The use of insecticides made from Tephrosia vogelii using nanoemulsion technology offers an environmentally friendly solution for this pest control. Nanoemulsion technology can produce very small particle sizes of nanometers that are adsorbed in liquids so that insecticides are more stable and effective. This study aims to test the effectiveness of botanical insecticide nanoemulsion made of Tephrosia vogelii against aphid pests on broccoli plants in the field. The research was carried out in the field, and the dose of field application refers to the results of laboratory research training (Tama, 2018). This study consisted of 4 treatments and six replicates, including K (Control), NTv (Nanoemulsion of vegetable insecticide made from T. vogelii), BT (bioinsecticide Bacillus thuringiensis), IS (synthetic insecticide with the active ingredient Abamectin). The results showed that the effectiveness of the three treatments included NTv 40.52%, BT 23.26%, IS 9.69%. There was a decrease in aphid populations in all three treatments. NTv (vegetable insecticide nanoemulsion made from T.vogelii) had the highest effect on aphids in broccoli plants in the field.

Abstract

Coffee is an exported commodity that is important in earning foreign exchange. The coffee berry borer (Hypothenemus hampei) is the most crucial pest that has a detrimental effect on coffee growers in Indonesia. Research on the incidence of fruit borer on Arabica and Robusta coffee was carried out on smallholder plantations in the Tanah Datar district. The study aimed to determine the extent to which fruit borers infest Arabica and Robusta coffee, and to determine the populations of these pests so that they could be compared. Observation variables included planting conditions and cultivation methods, percentage of coffee plants infested, percentage of coffee cherries, insect identification in the laboratory, and coffee berry borer populations. The results showed that the average incidence of Hypothenemus hampei infestation on Arabica coffee plants in Tanah Datar district was 30.00% and 36.66% on Robusta coffee plants. The percentage of the egg stage in Arabica coffee is 37% and 27% in Robusta coffee. The percentage of the larval stage in Arabica coffee is 33%, and in Robusta coffee, it is 28%. Stadia Pupa on 20% Arabica coffee, 11% Robusta coffee. Stadia imago on Arabica coffee 54%, Robusta coffee 49%. This study provides important insights for integrated pest management strategies in Tanah Datar, particularly in optimizing pest control for Arabica and Robusta coffee.

Abstract

Kegiatan pengabdian kepada masyarakat ini dilaksanakan untuk meningkatkan pengetahuan dan keterampilan petani dalam menggunakan insektisida nabati berbasis teknologi nano sebagai solusi alternatif dalam pengendalian hama yang ramah lingkungan. Sasaran kegiatan adalah Kelompok Tani Kubu Dalam, Parak Karakah, Kota Padang yang selama ini bergantung pada insektisida kimia sintetis. Metode kegiatan yang digunakan meliputi penyuluhan partisipatif, demonstrasi formulasi insektisida nabati, dan praktik langsung aplikasi di lahan. Materi difokuskan pada manfaat insektisida nabati, mekanisme kerja teknologi nanobubbles, serta tata cara pembuatan dan penerapan di lapangan. Hasil kegiatan menunjukkan peningkatan signifikan dalam pemahaman petani mengenai bahaya insektisida kimia dan potensi penggunaan insektisida nabati. Sebagian besar peserta menunjukkan antusiasme untuk menerapkan teknologi ini secara mandiri di lahan mereka. Kesimpulannya, edukasi mengenai insektisida nabati berteknologi nanobubbles mampu memberikan pemahaman baru dan mendorong perubahan sikap petani menuju praktik pertanian yang lebih berkelanjutan dan ramah lingkungan.
