Abstract

Chromolaena odorata (L.) is a potential compost since it has high biomass and contains calcium, manganese, potassium and nitrogen. The aim of this research was to know the potency of siam weed Chromolaena odorata compost on soil chemical and chili plant performance. The experiment was arranged in factorial randomized block design consisted of two factors and three replications. The first factor was variety of fertilizer (no fertilizer, cow manure, siam weed compost and inorganic fertilizers) and the second one was the tanglefoot (with and without tanglefoot). Overall, the results of study showed that C. odorata compost could increased crop performance when compared with the other fertilizers in terms of number of fruits, fresh/dry weight of fruits, dry weight of crops, and N-total (leaf, stem, root and fruit), though there was no difference in fresh weight of crops among treatments. Furthermore, the effect of siam weed compost was not significantly different on soil chemical if compared with all treatments. This study is likely suggesting that C. odorata compost gives a positive effect to crops performance and soil chemicals.Keywords:  Chili, Chromolaena odorata, compost  fertilizer, tanglefoot

Abstract

Laba-laba merupakan salah satu predator penting dalam mengatur populasi serangga hama di ekosistem padi. Aplikasi pupuk ampas bungkil mimba dan kompos gulma siam diharapkan meningkatkan keberadaan laba-laba. Tujuan penelitian adalah untuk menganalisis kelimpahan dan keanekaragaman laba-laba pada ekosistem sawah padi hitam berpupuk organik asal ampas bungkil mimba dan gulma siam. Percobaan dilaksanakan di Cinenggang, Desa Cileles, Kecamatan Jatinangor, Kabupaten Sumedang, sejak bulan Mei – November 2018. Penelitian dilakukan dengan metode Rancangan Acak Kelompok (RAK) dengan lima perlakuan yaitu kontrol, NPK, pupuk ampas mimba, kompos gulma siam, dan pupuk kandang sapi dengan dilakukan enam ulangan. Hasil penelitian diperoleh delapan famili laba-laba yaitu Tetragnathidae, Pholcidae, Linyphiidae, Lycosidae, Theridiidae, Oxyopidae, Clubionidae dan Araneidae. Famili yang paling dominan pada semua perlakuan adalah Tetragnathidae, dan selanjutnya diikuti oleh Famili Pholcidae dan Linyphiidae. Jumlah total laba-laba, indeks keragaman, kelimpahan, kekayaan dan kemerataan spesies diketahui cenderung lebih tinggi pada perlakuan pupuk ampas bungkil mimba dan kompos gulma siam daripada perlakuan NPK dan kontrol.
