Abstract

This research purposes to indentify the main factors influencing firm value that proxied by Price Book Value (PBV) especially in manufacturing companies sector listed on the Indonesian Stock Exchange (IDX) during period 2010-2015.The population of this research consists of manufacturing companies listed on the IDX period 2010-2015. This research used secondary data anda used purposive sampling method in determining the sample. The total of sample in this case are 50 companies. Multiple regression is used as the analysis technique in this research.The study documents the positive significant of financial performance, firm size, dividend policy and proportion of independent commissioner on firm value. While the disclosure of corporate social responsibility and insider ownership found influental positive but insignificant to firm value.

Abstract

This development research aims to produce a Science, Technology, Engineering, and Mathematics (STEM)-based e-module to determine the feasibility, practicality, and effectiveness of a STEM-based physics e-module on the topic of work and energy for 10th-grade students. The research design used in this study was research and development (R&D) using the ADDIE model to develop the e-module on the topic of work and energy based on STEM. The population and sample of this study were 10th-grade students at SMAN 1 Deli Tua, and the sample consisted of 10th-grade students in the MIA 3 class at SMAN 1 Deli Tua. Based on the data analysis, the results of expert validation yielded a material expert validation score of 88.16% with a category of very feasible, and a media expert validation score of 90.7% with a category of very feasible. The results of the practicality test on a small scale showed that the ease aspect obtained a percentage of 91.3%, the attractiveness aspect obtained a percentage of 91.8%, and the usefulness aspect obtained a percentage of 90.2%. The results of the large-scale trial showed that the e-module obtained a highly practical category, reaching 92.6%. The ease aspect obtained a percentage of 93.2%, the attractiveness aspect obtained a percentage of 94%, and the usefulness aspect obtained a percentage of 90%. Both small and large-scale tests yielded a highly practical category. The effectiveness test showed that the average pre-test score obtained by students was 37.66, and the average post-test score was 89.6%. Based on the N-gain test, it was found that the average N-gain score of students was 0.84 or 83.94%, which is interpreted as having high effectiveness. Therefore, the product developed in this study is considered feasible, practical, and effective in supporting students' self-directed learning process on the topic of work and energy and can improve students' learning outcomes
