ng digunakan dalam penelitian ini adalah rancangan acak lengkap (ral) non faktorial yang terdiri atas 4 perlakuan serbuk nabati yaitu serei wangi, daun babadotan, daun salam, dan kayu manis. peubah yang diamati meliputi mortalitas imago, mortalitas larva, persentase imago t. castaneum yang muncul, daya repelensi imago dan daya repelensi larva. hasil penelitian menunjukkan bahwa mortalitas imago tertinggi pada pengamatan 9 hsa dijumpai pada perlakuan serbuk kayu manis mencapai 56,67% dan mortalitas larva tertinggi pada pengamatan 5 hsa dijumpai pada perlakuan serbuk kayu manis mencapai 16,67%. selanjutnya persentase imago t. castaneum yang muncul tertinggi pada pengamtan 38 hsa dijumpai pada perlakuan serbuk daun salam sebesar 73,33%. daya repelensi imago tertinggi pada pengamatan 2 jsa dijumpai pada perlakuan serbuk kayu manis sebesar 60,00 % dan daya repelensi larva tertinggi pada pengamatan 2 jsa dijumpai pada perlakuan serbuk kayu manis sebesar 25,00%. kata kunci : serbuk nabati, cymbopogon nardus l. , ageratum conyzoines l. , syzygium polyanthum, cinnamomum burmani, tribolium castaneum, hama gudang bioactivity some vegetable powder against insects tribolium castaneum (herbst.) on corn seed laboratory broke nailul pitri program studi agroteknologi, fakultas pertanian, universitas syiah kuala banda aceh-indonesia jln. tgk. hasan krueng kalee no. 3 kopelma darussalam, banda aceh e-mail : nailulpitri@gmail.com, kode pos 23111 abstract. tribolium castaneum (herbst.) or flour beetle is one of the important warehouse pests in the tropic area, which is also known as secondary pests. this pest is in storage when the stored materials have been destroyed by sitophilus zeamais, and has polyphago us trait. t. castaneum damage stored material by way of drilling the outside to get into the inside of the material which have an impact on the quantity and quality of materials. this study aims to get the kind of plant powder which more potential as insecticides to t. castenum on corn kernels in storage. the design used in this study is completely randomized design (crd) non factorial consist of 4 treatment plant powders that cymbopogon nardus l., ageratum conyzoides l., syzygium polyanthum, cinnamomum burmani. the parameters observed is mortality of adult, larval mortality, the percentage of adult t. castaneum that appears, repellent power of adult and larvae of t. castaneum. the results showed that the highest adult mortality observed in 9 hsa is cinnamomum burmani treatment reached 56.67% and the highest larvae mortality at 5 hsa observations found in cinnamomum burmani reached 16.67%. furthermore, the highest percentage of adult t. castaneum that appears on 38 hsa observations found in syzygium polyanthum powder treatment reached 73.33%. the highest adult repellent power on 2 jsa observations found in the treatment of cinnamomum burmani reached 60.00% and the highest larvae repellent power observed in 2 jsa found in cinnamomum burmani treatment reached 25.00%. keywords: plant powder, cymbopogon nardus l., ageratum conyzoides l., syzygium polyanthum, cinnamomum burmani, tribolium castaneum, pest
