Abstract

The objective of this research were to produce a lesson plans and worksheets learning instrument design that corresponded to problem based learning models and analyze whether it was can improve student learning outcomes. This research development was done in classroom by using development research methods of Analysis Design Development Implementation and Evaluation (ADDIE). ADDIE method was used as a method for designing a lesson plans and worksheets that corresponded to it. Three stages of development of lesson plans and worksheets such as an assessment by a team of experts, small group, and a field test. Assessment by a team of experts based on theree aspects such as format, content, and language. In small group and field test based on a response of students sheet. The student response sheet contains of teacher's ability to teach. Worksheet assessment based on aspects of the format, content, and language. Assessment of student learning outcomes based on pretest and posttest were analyzed by ngain. The results of development of lesson plans and worksheets were validated by a team of experts on aspects of format, content, and language. The result both of development of lesson plans and worksheets in small group and field test produced good categories. There was an increased student learning outcomes of  first to third meeting with categories of low to moderate.

Abstract

This study examined the impact of organizational climate, compensation, and job placement on employee work commitment at the Department of Marine and Fisheries in Simeulue Regency. The objective was to assess both the individual and combined effects of these factors on employee commitment. The hypothesis suggested that enhancing organizational climate, fair compensation, and proper job placement would significantly boost work commitment. Using a quantitative approach with an associative design, the research included all 52 employees as the sample, applying a saturated sampling technique. Data were collected through structured questionnaires and analyzed using statistical tools to determine the significance of the relationships. The results revealed that organizational climate, compensation, and job placement positively and significantly influenced employee work commitment. Additionally, the combined effect of these factors had a stronger impact on commitment, highlighting the critical role of a supportive environment, adequate compensation, and appropriate job placement in fostering employee dedication. These findings emphasize the need to prioritize these elements to enhance employee commitment and improve organizational performance at the Department of Marine and Fisheries in Simeulue Regency

Abstract

This study aims to develop an objective test of conceptual knowledge of physics on Mechanical Waves material in high school that meets good test qualification standards, covering aspects of validity, reliability, level of difficulty, discriminating power and effectiveness of distractors. This type of research is research development or Research and Development (R&D), with the ADDIE model. The population of this study were all students of SMA Negeri 2 Percut Sei Tuan with the subject of all students of class XI MIA SMA Negeri 2 Percut Sei Tuan. The instrument used in this study was a multiple-choice test of 50 items to measure conceptual knowledge. The results showed that the content validity by experts of the objective test of conceptual knowledge of physics on Mechanical Waves material in high school was very good. Judging from the empirical validity of the broad field test, 37 valid items and 13 invalid items were obtained. The reliability of the test is 0.91. The level of difficulty obtained 7 easy questions, 27 moderate questions, and 4 difficult questions. The discriminatory power obtained 30 items very good, 5 items good, 2 items enough, and 1 item not good. Based on the effectiveness of the distractors, 20 distractors were found to be inefficient or the distractors were not functioning. This conceptual knowledge test can be used as a standard test to measure students' conceptual knowledge on the Mechanical Wave material in high school.
