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

Abstract

Global competitions require human resources that have competitive advantages, including in the field of education. UIN biology education program has responded by developing ICT-based lecture system. The development of the most up-to-date courses is e-learning, which is one of the learning system which use communication and information technology. Learning object becomes very important part. Students become accustomed to utilize the various learning sources available online. On the other hand, the ability to develop teaching materials is one of the required skill as professional teachers. The research purpose was to obtain more information about the ability of students to develop ICT-based teaching materials. This research used descriptive qualitative method, the assessment of teaching materials developed by students done before and after the lecture. The subject of research was the 25 students who were enrolled in Vertebrata courses. The validity of the teaching materials assessed by experts using specific instrument, students respond data also collected using questionnaire.The results showed that the average value given by the expert validators was 83 that fall into good category. While the average response of students to teaching materials fall into moderate category. Teaching materials developed by students before and after the lecture also showed significant changes. Before the lecture, all teaching materials developed by students are still in the form of power point. After attending lectures, the types of teaching materials developed by the students were varied. Those consist of wordpress (24%), wix (20%), webnode (12%), prezi (12%), android (8%), macromedia 3D Presentation, Power Point Inspiring, and Website UIN respectively by 4%. Keywords: ICT-based learning materials, learning object, e-learning.

Abstract

The high diversity of plant species makes the Kapas Biru Waterfall a suitable area of tourism, research and other related activities. The plant species in this area are mostly seed plants and shrub. The shrub is a tree-like plant but with shorter and smaller main stem. The woody stems alsobranching near the surface of the soil. The aim of this research was to find out the species of shrub plants in the area of Kapas Biru Waterfall. This descriptive explorative research was conducted to systematically, factually and accurately describe and interpret the data of shrub seed plants in the area of Kapas Biru Waterfall. The study was conducted from April to May 2017. The research design included the selection of research sites, sampling and drawing, and plant identification stages.Samples were collected using total explore sampling method. Research result showed that there are 562 shrub plants in Kapas Biru Waterfall. They consist of 19 species incorporated in 11 families. Those family are Asparagaceae, Rutaceae, Asteraceae, Euphorbiaceae, Oleaceae, Arecaceae, Verbenaceae, Rubiaceae, Melastomataceae, Solanaceae, and Araliaceae.

Abstract

Indonesian students got low achievement in many international studies of evaluation, such as in Trend in International Mathematics and Science Study (TIMSS). It is because they unfamiliar with higher order thinking skill questions. Generally, assessment in Indonesia contains less of higher order thinking questions and do not fit with the international standard of evaluation. The purposes of this study were to identify the test items of Test of Standarisasi Hasil Belajar (SHB) and to examine the capability of students of fifth grade to answer higher order thinking skills (HOTS) questions. The method uses was mix method (qualitative and quantitative). Test Standarisasi Hasil Belajar (SHB) Year 2017/2018 of Banyuwangi Regency for fifth grade was used. Twenty-seven fifth graders were participated in paper test. The result showed that the test contains of cognitive domain of knowing, applying, and reasoning of 48.9%, 40% and 11.1%, respectively. The test of capability of students to answer HOTS questions revealed low achievement of 80% and high achievement of 5%. In summary, the reasoning domain of the test should be more developed to encourage students’ capability in answering HOTS questions. Keywords: science test items, TIMSS, HOTS, fifth grade.

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.
