Abstract

The Control of Culex sp. using synthetic larvicides is harmful to the environment and human health. Biolarvicide from red shoot leaves (Syzygium myrtifolium) is a safe alternative for the environment and human health. This study aims to determine the effect of Syzygium myrtifolium leaves extract with ethanol solvent and water solvent on larval mortality and the LC50 values of these extracts. ANOVA test results (α = 0.05) on the mortality of Culex sp. larvae exposed to the ethanol extract and aqueous extract of S. myrtifolium leaves consecutively showed F-calculated (287)>F-tabulated (3,11) and F-calculated (153)>F-tabulated (3, 11). The treatment of S. myrtifolium leaves extract with ethanol and water solvents had a significant effect on the mortality of Culex sp. larvae. The LC50 value of the ethanol extract and the aqueous extract of S. myrtifolium leaves are 1659 ppm and was 2053.7 ppm. It can be concluded that S. myrtifolium leaves extracts with ethanol solvent and water solvent have an effect on the mortality of Culex sp. larvae, but are not yet effective as biolarvicide

Abstract

Research to measure students' Critical Thinking Skills has been widely carried out in Indonesia. However, the development of Critical Thinking Skill measuring tools in Ecology using CBT is still limited. This study is part of research and development to develop a good instrument product for measuring students' Critical Thinking Skills. The question preparation format uses a two tier multiple-choice form. This study aims to prove the content validity of the Critical Thinking Skill instrument in Ecology Subject for Senior High School. Scale using Likert model and multiple-choice model with content validity coefficient based on expert assessments with Aiken’s formula. There are three experts who assess the items' relevancy, construction, and clarity using indicators of both scale formats. The results of the expert assessments are then used to calculate the coefficient of the validity with Aiken formula. The results showed that the content validity coefficient based on expert assessment on Likert format with Aiken formula is at 0.75-1.00 for each, while using the Aiken formula.
