The aim of this research was to seek raw materials for preparing liquid smoke, and then evaluated in laboratory for knowing its effects on feeding, development and mortality of the cabbage head caterpillar, Crocidolomia pavonana (F.) (Lepidoptera: Pyralidae) on cabbage. Antifeedant activity of the liquid was tested against third-instar of the caterpillar larvae with leaf residual method in leaf disc no-choice tests and contact method. Result of the research showed that the liquid at concentration from 3 - 22% reduced feeding by 22.94 - 51.52%, and prolonged period of the caterpillar development to pupation by 0.27 - 0.33 days compared to controls. The effects of test liquid smoke on mortality of Crocidolomia pavonana third-and fourth (final)-instar larvae were fed for 48 h broccoli leaves treated with a leaf residual and dipping method. The result show that the treatment 3 - 22% liquid smoke was not caused larvae death. The effects of liquid smoke from coconut shell (a raw material of the chosen few) was to take possession of antifeedant activity from weak to moderate against C. pavonana larvae.The effects of antifeedant from weak to moderate were the liquid at concentration from 3 - 22%. All the above effects could not give substantial suppression of C. pavonana population if the liquid was used in the field.

Air dan nutrisi merupakan kebutuhan esensial tanaman. Perkembangan saat ini, budidaya melon dilakukan secara hidropononik dengan pemberian air irgasi dan nutrisi secara bersamaan (fertigasi). Nutrient Film Technique (NFT) dan irigasi tetes merupakan dua tipe teknik fertigasi yang banyak diterapkan. Kelemahan dan kelebihan dari kedua teknik fertigasi tersebut banyak dibahas mengenai aspek keteknikannya, sedangkan pengaruh terhadap pertumbuhan dan produktivitas tanaman masih jarang diteliti terutama pada varietas tertentu. Tujuan dari penelitian adalah mengetahui pengaruh teknik fertigasi terhadap pertumbuhan dan produktivitas melon pada budidaya secara hidroponik. Penelitian menggunakan rancangan acak kelompok (RAK) dengan 2 faktor bebas yaitu jenis teknik fertigasi (NFT dan irigasi tetes) dan varietas melon (varietas Jumbo F1 dan Golden aroma). Sedangkan variabel terikat yaitu pertumbuhan dan mutu melon (yaitu: tinggi tanaman, berat buah, diameter buah, dan kemanisan buah). Hasil penelitian menunjukkan bahwa jenis sistem fertigasi dan varietas melon berpengaruh nyata terhadap semua variabel terikat, meskipun tinggi tanaman baru terlihat berbeda nyata ketika masuk pada 3 minggu setelah pindah tanam. Berdasarkan parameter berat, diameter, dan tingkat kemanisan buah, kombinasi perlakuan terbaik dihasilkan pada perlakukan menggunakan NFT dan varietas Golden Aroma. Penelitian ini diharapkan dapat membantu petani melon dalam memilih jenis sistem fertigasi dan varietas unggul untuk mendapatkan hasil melon terbaik

Spodoptera frugiperda is a new pest in Indonesia that attacks corn and can cause up to 100 percent damageon young plants. As an invasive pest, information on potential indigenous natural enemies that cancontrol this pest is needed. This study aims to determine the effectiveness of indigenous entomopathogenic fungi and their application methods on mortality, feeding activity, growth, fecundity, and fertility of S. frugiperda. This study used a factorial Completely Randomized Block Design (RCBD) method consisting of 10 treatments. Treatmentstested werecombination of fungi species, namely Fusarium sp., Aspergillus oryzae, Entomophthora sp. with conidia density 109 ml-1, distilled water and cypermethrin at concentration of 1 ml.L-1 as a control. Two application techniques used were direct application on S. frugiperda larvae and diet test. Each treatment was repeated three times resulting in30 experimental units. Variables observed included mortality, feeding activity, growth, fecundity, and fertility of S. frugiperda. Results showed that the three fungi and cypermethrin treatment did not cause mortality, but reduced feeding activity, fecundity and fertility of S. frugiperda. Application of entomopathogenic fungi ondietswas more effective than directly spraying S. frugiperda larvae. The best treatment combination that suppressed feeding activity was the application of Aspergillus oryzae sprayed on S. frugiperda diet.It was also suspected that S. frugiperda larvae used in this test had developed resistance to cypermethrin.
