Abstract

Grayak caterpillar is insect pests that become pests of various food crops. Grayak caterpillars cause a decrease in crop productivity and even crop failure if they are not controlled. Pest control using chemical pesticides has many adverse effects on the environment. To minimize the occurrence of environmental damage, then it is used pest control using vegetable insecticides. Bintaro Leaf (Cerbera odollam Gaertn.) is potential as a vegetable insecticide. The purpose of this study was to examine the toxicity of granule from Bintaro leaf extract (C. odollam Gaertn.) on armyworms (S. litura Fab.). This research was a laboratory experimental research using Completely Randomized Design (CRD). Serial concentrations used in this study were 0% (control), 0.5%, 1%, 1.5%, 2%, and 2.5%. The results of this study showed that the granules of Bintaro leaf extract (C. odollam Gaertn.) were effective in causing mortality of armyworms (S. litura Fab.) at 1.5% concentration by 60% and included in toxic category. The value of LC50-48 hour granule from Bintaro leaf extract (C. odollam Gaertn) was 1.41%. Keywords: Spodoptera litura Fab. , Granula extract of Cerbera odollam Gaertn., Vegetable Insecticide.

Abstract

This research aimed at determining the validity of interactive multimedia on the nerve system material that had been developed and finding out the students’ response to the interactive multimedia. This was a developmental research (Research and Development) followed by a small group test on the eleventh-grade students of SMAN Ambulu totaling 9 students. The students were selected based on their ability level; 3 students with high ability level, 3 students with moderate ability level and 3 students with low ability level. The data collection techniques used were experts' validation sheets and questionnaires. The design of the interactive multimedia in this research was 4D (define, design, develop and disseminate) model developed by Thiagarajan (1974). The developmental procedure of 4D consists of 4 stages: (1) define, (2) design, (3) develop and (4) disseminate. The results showed that the validity of the developed interactive multimedia reached 82.9% according to the content expert, 86.3% based on the learning expert, 88,3% based on the learning media expert, and 82.7% based on the teacher’s (user) perspective. The results of small group test revealed that the legibility and the level of difficulty were 81.99% or in the good category, and student response score was 83.55%, it means that student had positive response toward the use of developed media in their learning. Keywords: interactive multimedia, 4D, expert validity.

Abstract

Armyworm (Spodoptera litura F.) is a leaf-eating pest causes the loss of crops from 85% until causing crop failure. Alternative pest control and to reduce the negative impact of synthetic pesticides include using botanical pesticide. Getih-getihan plant (Rivina humilis L.) is one of the plants having potency as a botanical pesticide. Based on the description, this study was conducted to determine LC50 value by using probit analysis and analysis of an extract of Rivina humilis L. leaves on the mortality of Spodoptera litura F. using ANOVA test. Rivina humilis L. leaves are extracted by using ethanol solvent to get active chemical to kill Spodoptera litura F.. TLC (Thin Layer Chromatography) result test of an extract of Rivina humilis L. are positively contain an alkaloid, flavonoid, tannin, and terpenoid. The method of the research uses CRD (Complete Random Design) with five times repetition. Concentration serial being tested are 0%, 0.5%, 1%, 1.5%, 2%, and 2.5%. The result of probit analysis is 1.42% of LC50 value and ANOVA test shows that extract of Rivina humilis L. leaves affects very significantly on the Spodoptera litura F. mortality (p=0.000). Keywords: Spodoptera litura F., Rivina humilis L., leaves extract.

Abstract

Armyworm (Spodoptera litura (Fabricius) often lead to decreased productivity and even crop failures by causing leaves, fruits, and vegetables to become torn, cut, and punctured. Crop insecticides are an alternative to eradicating armyworm (Spodoptera litura (Fabricius). One plant that can be used as a vegetable insecticide is bintaro (Cerbera odollam Gaertn.) The bintaro plant (Cerbera odollam Gaertn.) has cerberin content that contribute to insect mortality. This study aims to determine the effectiveness of extract (Cerbera odollam Gaertn.) on mortality of armywork (Spodoptera litura (Fabricius). This study was a type of experiment using Completely Randomized Design (CRD) with five treatments and one control. The results showed that the effectiveness of seeds bintaro extract (Cerbera odollam Gaertn.) could cause death to armyworm (Spodoptera litura (Fabricius) on 1.5% concentration of 55% showed effective on the armyworm. Increasing the dose is to be followed by increasing the effectiveness of mortality. The LC50 value is 1.51%. Increasingly concentration of seeds bintaro extract (Cerbera odollam Gaertn.) cause higher mortality of armyworm (Spodoptera litura (Fabricius). Keywords: Spodoptera litura (Fabricius), Cerbera odollam Gaertn. Seeds Extract, Mortality
