Abstract

Spodoptera frugiperda merupakan hama baru pada tanaman jagung di Indonesia dan dilaporkan menyerang tanaman jagung di berbagai wilayah di Indonesia. Informasi tentang biologi hama S. frugiperda pada berbagai pakan perlu diketahui untuk menentukan stadia pengendalian paling efektif dan kesesuaian pakan bagi pertumbuhan dan perkembangannya. Penelitian ini bertujuan untuk mengetahui lama siklus hidup dan periode perkembangan S. frugiperda yang diberi pakan berbeda. Penelitian ini menggunakan tujuh pakan daun yang berbeda, yaitu: kontrol (jagung), selada, pakcoy, kangkung, bawang daun, bayam cabut hijau, dan bayam duri hijau. Penelitian dilakukan dengan memelihara 10 ekor tiap unit percobaan. Perkembangan stadia perkembangan hama dicatat, dan pupa diukur panjang serta bobotnya. Hasil penelitian menunjukkan, inang yang berbeda dapat mempengaruhi pertumbuhan dan perkembangan S. frugiperda. Perlakuan yang menunjukkan siklus hidup paling pendek adalah pakcoy.

Abstract

Learning tends to be dominated by teachers, which causes some students to be passive in learning. This is thought to make the level of students' creative thinking skills low. This study aims to determine whether there are differences in the level of creative thinking abilities of students who use Open-ended based learning with Problem Based Learning (PBL) methods with those using Conventional learning methods for students' creative thinking skills of VIII Grande students of State Junior High School (SMP Negeri) 2 Majenang Cilacap Regency At Odd Semester In Academic Year of 2018/2019. The population in this study there are eight classes. The sample was taken by two classes with a random sampling technique for the class and selected VIII-G class as the control class and VIII-H as the experimental class. The design in this study is the Pretest-Posttest Control Group design. Data collection techniques using test techniques (pretest and posttest) and questionnaire techniques. Data collection instruments in the form of tests and test questionnaires. Test data collection instruments using validity, discriminating power, and reliability tests. Data analysis techniques using analysis prerequisite tests include normality test, homogeneity test, and hypothesis testing using the t-test. The study results at a significant level of 5%, and df = 61 indicate that: (1) there is a difference in the value of posttest mathematics using open-ended-based learning with problem-based learning (PBL) method with learning using conventional methods. This is indicated by ttable = t (0,025) (61) = 1,996 and tcount = 2,988762 which means ttable< tcount(2) Learning using Open-ended PBL method is more effective than learning using conventional methods. This is indicated by the value of tcount = 2.988762 and ttable = t (0.025) (61) = 1.670385 which means tcount>ttable .

Abstract

Spodoptera frugiperda JE Smith. is a new pest on maize plants in Indonesia and is polyphagous. The purpose of this study is to find out what plants are lettuce and pakcoy can be used as potential hosts for S. frugiperda, its life cycle, sex ratio and number of eggs produced in the laboratory. The research was conducted in October 2019 - January 2020. Treatment and observations were carried out at the Botanical Laboratory, Ahmad Dahlan University. The parameters taken were the average value of larvae length, head diameter, weight of instar larvae 3 - 6, length and weight of pupa, sex ratio, number of eggs, and life cycle length of S. frugiperda. The highest average value of all observed parameters was pakcoy leaves. The length of time needed for one life cycle is the fastest for pakcoy leaves for 37 days. This study showed that lettuce and pakcoy plants could be used as potential hosts with the best growth in the treatment of pakcoy leaves. Keywords: Brassica rapa, Lactuuca sativa, pakcoy , lettuce, S. frugiperda

Abstract

Media is a very effective tool used for learning. This research is motivated by the lack of learning media in schools. This study aims to determine the steps of media development, media quality by experts, teachers and students. This research is a type of research and development (R&D) ADDIE development methods, namely analysis, design, development, implementation and evaluation. Data collection techniques using expert validation sheets, student assessment sheets and teacher assessment sheets are then analyzed using qualitative and quantitative data.The results of this study indicate that research and development has been carried out with the ADDIE step, the results of the study showed that the development of puzzle media based on make a match material for the life cycle of living creatures in fourth grade elementary school was declared feasible and received positive responses from students and teachers. The results of the validation produced by media experts got a value of 98 in the excellent category. the value resulting from the validation of the material experts obtained 85.3 in good category and the validation results produced by learning experts obtained 84 grades in good categories. With the final average overall results obtained 92.5 with a very good category.
