Abstract

The mastery learning model using Image Series media is a learning process by fully mastering the material assisted by media, namely a series of images. This research aims to determine the effect of the mastery learning model using a series of image media on the essay writing ability of Class IV students at the Miftahul Ulum Banjarejo Lamongan Elementary School. This type of research is quantitative using a pre-experimental design method type one group pretest-posttest (initial test – single group final test). The data collection methods used are observation, testing, and documentation. The data analysis techniques used are descriptive analysis, normality testing and hypothesis testing. The results of the research show that the application of the Mastery Learning model using a series of image media averages 82% in the very good category. The students' essay writing ability obtained in the pre-test got an average score of 57.28 in the sufficient category in the range of 40- 60, while the post-test got an average score of 82.71 in the very good category in the 80-100 range. The results of the normality test analysis with the help of SPSS and the results of the significance value are 0.010 > 0.05, it can be concluded that the residual values ​​are normally distributed. followed by hypothesis testing, namely by using a simple linear regression test with the help of SPSS with the provisions Sig < α, namely 0.000 < 0.05 and count < ttable, namely 7,468 > 0.444, which means that Ha is accepted and Ho is rejected, so there is an influence of using the mastery learning model using series image media. on the ability to write Indonesian essays for class IV students. By carrying out this research, it is hoped that teachers can create interesting variations of learning in the classroom with the hope that learning activities can be more enjoyable, and students will be more active so that students' ability to write Indonesian essays will increase.

Abstract

Sexava (coconut long-horned grasshopper) is a genus of the suborder Ensifera that has the ability to attack coconut plants massively and rapidly. Sexava is also known as a long-horned grasshopper because it has antennae longer than its body and a sword-like ovipositor in the female insect. Three Sexava species, namely Sexava coriacea, S. nubila, and S. karnyii, have distributions restricted to eastern Indonesia. All three long-horned grasshopper have almost identical visual appearances when encountered in plantations. Morphological observation of these insects in the field is difficult due to similarities in body size and color. This study aimed to characterize the morphological differences among S. coriacea, S. nubila and S. karnyii under laboratory conditions. Specimens of S. coriacea were obtained from North Maluku, S. nubila from West Papua, and S. karnyii from Central Sulawesi. Collection and identification of Sexava were carried out using direct observation methods based on the Sexava identification key by The Key of Sexavae and comparison specimens. The results show that the specific differences among Sexava coriacea, S. nubila, and S. karnyii can be seen from body morphology, especially the stridulatory on wings, cerci and the subgenital plate. Female genitalia among S. coriacea, S. nubila, and S. karnyii do not show significant differences and therefore are not used as distinguishing parameters.
