Abstract

The almond moth Cadra cautella (Walker) is a notable stored product pest which can cause detrimental loss on stored cocoa. Cocoa can be stored in bean and powder forms. The information about survival and development of C. cautella on stored cocoa is limited. This research aimed to determine the effect of cocoa powder and cocoa bean in the storage against the survival and development of C. cautella. This research was conducted in Plant Pests Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Brawijaya. This research consisted of two treatments namely cocoa bean and cocoa powder with no choice method and repeated six times. The observed variables were number of larvae, pupae, male and female almond moth of F1 progeny, and developmental time of this insect. The t-test analysis was applied to determine the treatment effect. Results showed that the number of larvae, pupae, adult males and females of F1 progeny cultured on cocoa powder were significantly higher than on cocoa bean. The total developmental time and life cycle of almond moth were shorter on cocoa powder than on cocoa bean. Therefore, to store cocoa in powder form is riskier to the almond moth infestation rather than in bean form. Hence, it is suggested to take more concern on the cocoa powder storage better in order to minimize the almond moth infestation.

Abstract

Jagung merupakan tanaman sumber karbohidrat sehingga mempunyai nilai strategis dan nilai ekonomis yang tinggi, akan tetapi praktik budidaya tanaman jagung mengalami berbagai kendala, salah satunya adalah keberadaan gulma pada lahan budidaya yang berpotensi menurunkan produksi tanaman jagung. Upaya pengendalian gulma oleh petani saat ini kurang efektif dan efisien karena kurangnya pemahaman tentang vegetasi gulma yang tumbuh. Penelitian ini bertujuan untuk menganalisis vegetasi gulma dan menentukan gulma dominan pada lahan budidaya jagung di Kelurahan Arcawinangun, Kecamatan Purwokerto Timur, Kabupaten Banyumas. Penelitian ini menggunakan metode kualitatif dengan mengidentifikasi gulma yang ditemukan, dan metode kuantitatif dengan menghitung dan menganalisis vegetasi gulma yang dominan. Pengambilan sampel dilakukan dengan metode Kuadrat menggunakan plot ukuran 0,5 x 0,5 m2 secara acak dengan melemparkan plot ke lahan budidaya jagung sebanyak 10 kali sehingga terdapat 10 plot sampel. Hasil penelitian menunjukkan bahwa terdapat 11 spesies gulma yang tumbuh pada lahan budidaya jagung di Kelurahan Arcawinangun, Kecamatan Purwokerto Timur dengan komposisi 6 termasuk golongan gulma berdaun lebar, 3 termasuk golongan gulma rerumputan, dan 2 termasuk golongan gulma teki. Gulma yang mendominasi pada lahan tersebut adalah Synedrella nodiflora dari golongan gulma berdaun lebar dengan nilai SDR sebesar 31,1%, dan Cyperus iria dari golongan teki dengan nilai SDR sebesar 23,8%.
