Abstract

Ekstrak daun bunga pukul empat (Mirabilis jalapa), memiliki senyawa metabolit sekunder yang dapat dimanfaatkan sebagai botani pestisida. Selain itu, sinergisme ekstrak daun tanaman ini dengan mikroba entomopatogen seperti jamur entomopatogen untuk memaksimalkan efek dan daya kerjanya dalam mengendalikan serangga. Namun demikian,  perlu mempelajari aktivitas antijamur ekstrak daun M. jalapa terhadap jamur.  Penelitian ini menggunakan ekstrak M. jalapa konsentrasi 0 (kontrol), 0,1; 0,2; 0,4; dan 0,8 % (b/v). uji antijamur menggunakan metode difusi agar. Hasil penelitian menunjukkan ekstrak daun dari M. jalapa tidak menghambat aktivitas jamur Rizoctonia dan Fusarium sehingga memungkinkan ekstrak daun M.jalapa dapat dikombinasikan dengan jamur untuk penelitian lanjutan mengenai kombinasi botani pestisida.

Abstract

Abstract. Caterpillar grayak (Spodoptera litura) is one of the pests in various types of vegetable plants are polyphagous and have a wide range of hosts. One common way of controlling farmers to overcome Spodoptera litura attack is to use insecticide. The use of insecticides that are not rational will accelerate the occurrence of pest resistance against insecticides. An alternative is needed to develop biological products which are generally narrow-spectrum chemicals to target organisms. Flowers at four (Mirabilis jalapa) contain bioactive compounds that are toxic. M. Jalapa contains some secondary metabolite compounds such as saponins, flavonoids, tannins, and polyphenols. Based on the description above it is necessary to conduct a research to determine the percentage mortality of caterpillar grayak on giving the leaf extract at four o'clock flowers. The method used is leaf dipping methods and analysis with POLO-PC software. The results showed that 1.6% concentration of extract of M. jalapa can kill the number of larvae as much as 30 tails with a percentage of 75% within 48 hours. The LC50 value of mortality of M. jalapa extract on Spodoptera litura larvae was 0,507% (0,378-0,661 with p <0,05) with slope1,516 ± 0,318.Keywords: Bioinsecticides, Mirabilis jalapa, Spodoptera litura, Mortality

Abstract

Abstract. The larval stage of the armyworm (Spodoptera exigua), has a high and polyphagous feeding activity so that these insects have the potential to be pests in agriculture. The use of botanical pesticides in this case Mirabilis jalapa, is expected to control agricultural pests so that research on the immune system of S. exigua larvae is carried out by observing lectins that play a role in analyzing foreign molecules that enter the insect's body. The results were obtained, the higher the M. jalapa concentration, at the concentration of M. jalapa 0.4% and 0.8%, the lower the hemolymf agglutination titers. This is thought to decrease the binding capacity of lectins to foreign molecules. So that M. jalapa has the potential to be used as an environmentally friendly botanical pesticide.Keywords: agricultural pests, botanical pesticides, lectin agglutination.

Abstract

Abstract. Scabies disease or in society better known as scurvy is a parasitic infection of the skin caused by Sarcoptes scabei var hominis. The incidence of scabies in developing countries shows a cycle of fluctuation or increase. The distribution, prevalence, and infection of this parasitic skin disease depend on the area and population studied. This counseling was held in Takalar District with 15 respondents as being school teachers. Outreach results obtained knowledge of the increase in respondents' knowledge. The average proportion of knowledge before counseling was 60.83%, after counseling it increased to 92.22%.Keywords: Scabies, Counseling, Takalar
