ABSTRAK

Limbah hasil penyulingan tanaman atsiri berpotensi sebagai mulsa dan repelen (penolak) hama serangga, sehingga perlu dilakukan penelitian. Penelitian ini bertujuan untuk memanfaatkan mulsa dari limbah tanaman atsiri yang dikombinasikan dengan aplikasi pestisida nabati untuk mengendalikan Crocidolomia binotalis pada tanaman brokoli. Penelitian dilaksanakan di Kebun Percobaan Manoko, Balai Penelitian Tanaman Rempah dan Obat (Balittro) sejak Maret sampai Agustus 2011. Penelitian dirancang dalam acak kelompok, dengan sembilan perlakuan dan diulang tiga kali. Perlakuan terdiri dari limbah nilam dan serai wangi yang dikombinasikan dengan aplikasi insektisida nabati BP1 (formula minyak cengkeh, serai wangi dan temulawak) dan BP2 (formula minyak cengkeh, serai wangi dan jarak pagar) serta insektisida kimia sebagai pembanding, dan tanpa aplikasi (kontrol). Pengamatan dilakukan terhadap tingkat kerusakan tanaman akibat serangan hama C. binotalis, produksi tanaman, kadar N tanah dan populasi mikroba di dalam tanah sebelum tanam dan sesudah panen. Hasil penelitian menunjukkan bahwa kombinasi aplikasi limbah tanaman atsiri dengan insektisida nabati berbahan aktif eugenol, sitronellal dan xanthorizol (BP1) berbeda nyata positif dengan perlakuan kontrol tetapi berbeda nyata negatif dibandingkan dengan kombinasi aplikasi insektisida sintetis terhadap kerusakan akibat serangan C. binotalis. Perlakuan insektisida mampu memberikan kenaikan hasil 14% lebih tinggi dibanding kontrol. Kenaikan produksi yang tertinggi dihasilkan oleh perlakuan kombinasi aplikasi limbah nilam dengan insektisida sintetis yaitu sebesar 40%. Aplikasi limbah tanaman atsiri tidak menaikkan secara nyata unsur N, tetapi memberikan kontribusi yang nyata unsur K terutama aplikasi limbah nilam. Aplikasi limbah nilam berpengaruh terhadap pertumbuhan dan produksi brokoli.

ABSTRACT

In associated with potentially essential oil plant waste distillate as mulch and insect pests repellent, further research needs to be done. The aims of this study were to find out the effectiveness of essentitial oil plant waste as mulch combined with botanical insecticide applications to control Crocidolomia binotalis on broccoli plant. The experiment was conducted at Manoko Research Station, Indonesian of Spice and Medicinal Crops Research Institute (ISMCRI) since March to August 2011. The experiment was designed in a randomized block, with nine treatments and three times replications. Treatment consists of patchouli and citronella waste combined with botanical insecticide application of BP1 (formula mixed of clove oil, patchouli oil and temulawak oil) and BP2 (formula mixed of clove oil, patchouli oil and jatropha oil), chemical insecticides and control (untreated plot). Observations were made on the level of crop damage due to C. binotalis, crop production, soil N content and microbial population in the soil before planting and after harvest. The results showed that combination application of sewage plants with insecticidal essential oils BP1 significantly different positively from the control treatment; but significantly different negatively compared with a combination of synthetic insecticide application to damage by insect pests C. binotalis, than it was able to give yield 14% higher compared than control. The highest increase in production generated by combination of patchouli waste
