Abstract

Various natural and human factors have fragmented the populations of Mudskippers, which will disrupt their existence in the wild population, especially their mangrove habitat in East Java. Classification of relationships is identified as a first step in efforts to conserve fish outside their natural habitat. The relationship determination is based on phenetic characteristics supported by morphometric, meristic, and morphological characters. The purpose of this study was to identify the relationship of gelodok fish based on phenetic characters. The method used in the phenetic analysis is UPGMA (Unweighted pair-group using arithmetic) using NTSYSpc 2.01 software. There are four types of fish can be found in those areas, which are: Periophthalmodon schlosseri, Periophthalmus argentilineatus, Boleophthalmus pectinirostris, and Boleophthalmus boddarti. Based on the dendrogram of morphological analysis results, apomorphy A and apomorphy B were obtained, namely the Periophthalmodon schlosseri clade and the Periophthalmus argentilineatus clade with a similarity level of 90.322% and the Boleophthalmus pectinirostris clade and the Boleophthalmus boddarti clade with a similarity level of 78.494%. The relationship between the species Periophthalmodon schlosseri and Periophthalmus argentilineatus is very close with a value of 90%. While the species Boleophthalmus pectinirostris and Boleophthalmus boddarti have a closely relationship with a value of 78%. It is recommended to develop targeted conservation strategies to protect the most unique and vulnerable populations.

Abstract

The abstract nature of the Periodic Table of Elements necessitates interactive learning media to improve students’ motivation and learning outcomes. This study aims to determine the effectiveness of the Chem Piano game as a learning medium in enhancing students’ learning motivation, learning outcomes, and retention of learning outcomes related to the Periodic Table of Elements material. The research design employed was a pre-experimental approach using a One-Group pretest-posttest design. Data on students’ learning motivation were analyzed using a Likert scale consisting of positive and negative statements. Chem Piano was categorized as meeting the criteria for good learning motivation if it achieved a score of ≥ 69%. The learning outcome test data were analyzed using descriptive statistics to examine the mean and percentage of achievement, and the Wilcoxon Signed Ranks Test was used to determine the significance of the increase in learning outcomes. The results showed an increase in learning motivation, with a shift in category from low to very high. The Wilcoxon Signed Ranks Test for student learning outcomes yielded a significance value of 0.00 (< 0.05), indicating a statistically significant improvement between the pretest and posttest scores. Furthermore, the retention analysis yielded a very high retention value of 92.3%, indicating that students’ learning retention was stable. Based on the analysis and discussion, it can be concluded that the Chem Piano game is an effective learning medium for enhancing students’ motivation and learning outcomes in chemistry, particularly in relation to the Periodic Table of Elements. Therefore, it is recommended that this medium be used as an alternative instructional tool to enhance students’ motivation and learning outcomes, and that its implementation be further explored with a larger number of students.
