Abstract

This study aims to determine the quality of the questions quantitatively (reliability, discriminating power, difficulty level, and distractor effectiveness). This research is descriptive research. The population in this study were all student answer sheets in the Middle Semester II Science Assessment Exam class VIII SMP Negeri 2 Koto XI Tarusan Academic Year 2020/2021. The sampling technique used total sampling with a sample size of 107 student answer sheets. Data were analyzed using ANATES ver. 4.0.2 program. Based on the research results obtained: 1) reliability of 0.50 with sufficient criteria; 2) the distinguishing power of the bad and good categories which dominates, namely 30% while 25% is moderate and 7.5% is very good; 3) the level of difficulty obtained by the criteria was medium with 62.5%, while the easy questions were 15%, the difficult questions were 12.5% and the very difficult questions were 2.5%; 4) the effectiveness of the distractor, there were 35 items or 87.5% of the effectiveness of the distractor which was functioning properly. Meanwhile, for 5 items, the quality of the distractor does not function or has very poor effectiveness. Thus, it can be concluded that these questions have met the criteria for good questions, but some questions need to be revised.

Abstract

Carp (Cyprinus carpio L.) is one of the oldest and most commercially cultivated freshwater fish in the World. However, there are still many undetermined phylogenetic relationships and the origins of common goldfish lineages, which are an obstacle to the conservation and genetic reproduction of this species. In the process of phylogenetic analysis, researchers used mitochondrial genomes where the genomic DNA was obtained from homozygous double haploid clonal lines from domesticated Songpu strains, and the total genomic DNA was extracted and sequenced using next-generation sequencing technology. Complete mitochondrial genome sequencing of 11 individuals representing East Asia and Europe and phylogenetic analysis was performed. The purpose of this study is to provide information about the phenology of Cyprinus carpio fish, which is expected to be the basis for increasing understanding to determine the kinship relationship between Cyprinus carpio in East Asia and Europe. The results showed that the relationship between Cyprinus carpio color, Cyprinus carpio songpu mirror carp, Cyprinus carpio carpio, and Cyprinus carpio wuyuanensis was very close, this can be seen from the bootstrap value of 100%. Meanwhile, with Cyprinus carpio haematopterus has a bootstrap value of 70%. Meanwhile, with Cyprinus xingguonensis it has a bootstrap value of 66%. Furthermore, it can also be said that the Songpu mirror goldfish is closely related to C. carpio carpio which is also a member of the genus Cyprinu. The genus Cyprinu has a close relationship with the genus Catla. In the phylogenetic tree, this species of fish forms a very coherent group, supported by a high bootstrap value of 100% and an average genetic distance of 0.02. Key words: Mitochondrial genome, Phylogenetics, general Cyprinus carpio
