Abstract

Plants in general are able to produce secondary metabolite compounds that act as a protector against predators. Gewang fruit is often used by the people of Kolbano Village as a natural poison to catch fish.. The purpose of this study is to analyze the cyanide (CN) compound content in gewang fruit (Corypha utan Lamk). This study uses a trimetric method. There are two types of samples used in this study, namely raw samples and dry samples. The results of the qualitative testing of the cyanide compound content in the gewang fruit on 2 (two) samples showed that the color changed from yellow to white and a precipitate was formed at the bottom of the solution when reacted with AgNO₃, which showed that the gewang fruit positively contained cyanide compounds (CN). The average cyanide content in the raw gewang fruit samples was 11.52 mg/L or 9.25%. Meanwhile, the average cyanide level in the dry samples was 18 mg/L or 17,19 %.

Abstract

Learning outcomes are an important part of achieving the learning process. Classroom learning must achieve learning objectives. To realize these objectives and learning outcomes, teachers need to plan and design learning as well as possible so that indicators of success can be realized. One thing that supports this is the use of learning media. Learning media is a medium that can convey learning messages and can be accepted and understood by students. In relation to this research, the researcher aims to conduct research by implementing a dictionary based on local plants in the Sabu area. The research method used is descriptive qualitative with a one-group pretest-posttest design. The number of students in the experimental class was 32. Based on the results of the study, a 2-tailed sig value (0.001) <0.05 was obtained, which means there was a significant difference in student learning motivation before and after the experimental treatment. Student learning motivation after the experiment was higher than student motivation before the experiment. Therefore, it can be said that the application of the illustrated dictionary has a significant effect on student learning motivation.
