Abstract

Background: Garcil (Allium sativum) is an important commodity and has high economic value in Indonesia.Studies have been using water extracts of garcil as larval mortality Crocidolomia binotalis in august –september 2014. This study aimed to determine the effect of water extract of Garlic (Allium sativum) on mortality of larvae on cabbage plants Crocidolomia binotalis. Methods: This study was an experimental study, using a rando mized block design (RBD), using the control group, and treatment concentraction of water extracts of garlic (Allium sativum). Concentration ranging from 2%, 4%, 6%, 8% with observation for 24 hours. Data effect of aqueous extract of garlic is effective against larval mortality Crocidolomia binotalis analyzed by real difference test (LSD) and the determination of the value of LC50, using SPSS.

Abstract

Ulat daun kubis (Plutella xylostella L., Lepidoptera: Plutellidae) adalah hama utama yang sangat merusak tanaman Brassicaceae, terutama kubis, sawi, dan caisin di Indonesia (Kartosuwondo 1994; Winasa dan Herlinda 2003). Salah satu upaya ysng dilakukanoleh para tani dalam melindungi melindungi tanaman dari hama yaitu menggunakan bahan kimia. Namun bahan kimia itu sendiri memiliki efek negatif terhadap kesehatan kita dan juga lingkungan sekitar. Oleh karena itu dipakai bahan alami sebagai pengendali hama yaitu batang serai dapur (Cymbopogon citratus L.) Kandungan kimia dari serai adalah senyawa sitral, sitronela, geraniol, mirsena, nerol, farnesol methil heptenol dan dipentena.Tujuan penelitian ini yaitu untuk mengetahui Konsentrasi yang efektif terhadap mortalitas hamaPlutella xylostella danNilai LC50 yang tepat terhadap mortalitas hama Plutella xylostella. Penelitian ini bersifat eksperimental dengan menggunakan rancangan acak lengkap. Subjek penelitian adalah hama Plutella xylostellaL. Instar III sebanyak 50 ekor. Konsentrasi yang digunakan 10 g, 20 g, 30 g, 40 g dengan kontrol negative 0 g (aquades) dengan 5 kali pengulangan setiap kelompok perlakuan. Pengamatan dilakukan 24 jam setelah penyemprotan dan hasil yang didapatkan yaitu terjadi peningkatan kematian hama seiring dengan meningkatnya konsentrasi. Kemudian data dianalisis Untuk mempelajari tingkat keragaman mortalitas akibat perlakuan, dilakukan analisis sidik ragam (Anova) sedangkan uji probit dengan maksud menghitung nilai lethal consentration.Berdasarkan hasil analisis sidik ragam terlihat pada nilai Fhitung (41.962) > F tabel (2.866).Hal ini membuktikan bahwa pemberian ekstrak batang serai berpengaruh secara signifikan terhadap mortalitas Plutella xylostella pada tanaman sawi (Brassisca juncea). Hasil analisis probit LC50 diperoleh pada konsentrasi ekstrak batang serai sebesar 21.277% dengan batas bawah 17.782 dan batas atas 24.824, artinya pada konsentrasi 21.277% ekstrak batang serai mampu mematikan 50% hama Plutella xylostella yang digunakan setelah pemberian ekstrak selama 24 jam pada tingkat kepercayaan 95%

Abstract

Penelitian ini bertujuan untuk mengetahui efek biolarvasida ekstrak etanol daun cengkeh penyebab mortalitas nyamuk Anopheles sp. dan dosis ekstrak etanol daun cengkeh yang efektif sebagai biolarvasida. Penelitian ini menggunakan rancangan acak lengkap (RAL), dimana 525 larva Anopheles sp. dibagi dalam 7 kelompok dengan 3 kali ulangan, larva Anopheles sp. diletakan dalam 21 gelas plastik, dimana masing-masing plastik berisi 25 ekor larva Anopheles sp. Hasil yang diperoleh dianalisis dengan Analysis of Variance (ANOVA) dan dilanjutkan dengan uji duncan pada tarif nyata a = 0.05 menggunakan perangkat lunak SAS dan dilanjutkan dengan uji beda nyata terkecil untuk mengetahui perbedaan perlakuan yang diberikan. Hasil Penelitian menunjukkan bahwa ekstrak etanol daun cengkeh kosentrasi 0.50%, 1%, 1.50%, 2%, 4%, 6% memiliki efek biolarvasida penyebab mortalitas larva nyamuk Anopheles sp. dengan konsentrasi yang efektif adalah 6% dan persentasi mortalitas larva nyamuk Anopheles sp. sebesar 100% pada jam ke-9.

Abstract

Red chili (Capsicum annuum L.) is an important commodity and has high economic value in Indonesia. Problems encountered in the cultivation of chili in Indonesia decreased productivity due to pests attack. Aphids (Aphis gossypii) is a major pest that attacks the chili leaves. This research was aimed to determine the effectiveness of ered pepper (Capsicum annuum L.) extract on mortality of aphids; especially  the effective concentration and LC50 of red chili extract on mortality of aphids (Aphis gossypii). This research tested five concentration of chili extract treatments with four replicates each. Third instar of nymphs were fasted for 30 minutes before, then nymphs attached to the chili leaves were trasferred into the petri dish. Each petri dish filled with 10 nymph of Aphis gossypii. Red chili extract of 3%, 5%, 7% and 9% sprayed 3 times on the nymph. Mortality rate was calculated 24 hours after application. The results showed that the extract of red pepper were effective to kill aphids nymphs, the lowest mortality was  35% at a concentration of 3% and the highest one was up to 92.5% at a concentration of 9%. Effective concentration (LC50) extract of red pepper that cause 50% of the mortality of the aphids for 24 hours of testing was  7.46%.

Abstract

Cabbage leaf caterpillars (Plutella xylostella L., Lepidoptera: Plutellidae) are the main pests that are very damaging to Brassicaceae plants, especially cabbage, mustard greens, and caisin in Indonesia. The chemical content of lemongrass is citral, citronella, geraniol, mirsene, nerol, farnesol methil heptenol and dipentene. The purpose of this study was to determine the effective concentration of Plutella xylostella pest mortality and the right LC50 value of Plutella xylostella pest mortality. This research is experimental using a completely randomized design. The subjects were 50 plutella xylostella L. Instar III pests. The concentrations used were 10 g, 20 g, 30 g, 40 g with negative control 0 g (aquades) with 5 repetitions for each treatment group. Observations were made 24 hours after spraying and the results obtained were an increase in pest death with increasing concentration. Based on the results of analysis of variance seen in the calculated F value (41,962)> F table (2,866). This proves that the administration of lemongrass stem extract significantly influences the mortality of Plutella xylostella in mustard plants (Brassisca juncea). The results of LC50 probit analysis were obtained at the concentration of lemongrass extract at 21,277% with a lower limit of 17,782 and an upper limit of 24,824, meaning that at a concentration of 21,277% lemongrass extract was able to kill 50% of the Plutella xylostella pest used after 24 hours of administration at a 95% confidence level.
