<![CDATA[The control of aphids pests in chilli plantation often uses scheduled chemical control. This study aims to determine the development of aphid populations in the vegetative phase of chili plants treated with biochar from agricultural waste and trichokompos, and its control based on the threshold of control. The experiment was conducted on Chili Varietas Kencana of vegetative phase in Sangir Tengah Village, Kayu Aro Subdistrict, Kerinci Regency in 2016. The planting of chili was carried out with five treatments: 1) Trichokompos 10 ton/ha and 2 ton/ha of bagasse biochar; 2) Trichokompos 10 ton/ha and 2 ton/ha of corncob biochar; 3) Trichokompos 10 ton/ha and 2 ton/ha of rice husk biochar; 4) Trichokompos 10 ton/ha; and 5) Control (farmer technology). Each treatment was repeated 4 times. The environmental design used is Group Random Design (RAK). Data collection through observation of population number of aphids done every week. Control measures with the use of pesticides are carried out after the population passes the economic threshold. The results showed that the use of agricultural waste biochar (rice husk, corncob, bagasse) and trichokompos did not significantly affect the number/population of aphids. Chemical control of aphids on chili plants in the vegetative phase based on the control threshold can reduce the frequency of insecticide application up to 50%.Keywords: control threshold, insecticide, chili pest AbstrakPengendalian hama kutu daun pada tanaman cabai sering menggunakan pengendalian kimia yang terjadwal. Penelitian ini bertujuan untuk mengetahui perkembangan populasi kutu daun pada fase vegetatif tanaman cabai yang diberi perlakuan biochar asal limbah pertanian dan trichokompos dan pengendaliannya berdasarkan ambang kendali. Penelitian dilaksanakan pada pertanaman cabai varietas Kencana fase vegetatif di Desa Sangir Tengah, Kecamatan Kayu Aro, Kabupaten Kerinci pada tahun 2016. Penanaman cabai dilaksanakan dengan lima perlakuan yaitu : 1) Trichokompos 10 ton/ha dan biochar ampas tebu 2 ton/ha; 2) Trichokompos 10 ton/ha dan biochar tongkol jagung 2 ton/ha; 3) Trichokompos 10 ton/ha dan biochart sekam padi 2 ton/ha; 4) Trichokompos 10 ton/ha; dan 5) Kontrol (teknologi petani). Masing-masing perlakuan diulang sebanyak 4 kali. Rancangan lingkungan yang digunakan adalah Rancangan Acak Kelompok (RAK). Pengumpulan data melalui pengamatan jumlah populasi kutu daun yang dilakukan setiap minggu. Tindakan pengendalian dengan penggunaan insektisida dilakukan setelah populasi melewati ambang ekonomi. Hasil penelitian menunjukkan bahwa penggunaan biochar limbah pertanian (sekam padi, tongkol jagung, ampas tebu) dan trichokompos tidak berpengaruh nyata terhadap jumlah/populasi kutu daun. Pengendalian kimia kutu daun pada tanaman cabai varietas Kencana pada fase vegetatif yang dilakukan berdasarkan ambang kendali, dapat menurunkan frekuensi aplikasi insektisida sampai 50%.Kata kunci : ambang kendali, insektisida, hama cabai]]>
