Abstract

The purpose of this study was to determine the effect of work environment and work motivation on Organizational Citizenship Behavior with job satisfaction as an intervening variable, with all employees of PT Pelindo Multi Terminal Cilacap as respondents. A quantitative approach was chosen to analyze the effect of each variable and use data sourced directly from all employees of PT Pelindo Multi Terminal Cilacap, which is presented in the Linkert scale. The application used is Partial Least Square (PLS) with SmartPLS version 3.2.9 program to present descriptive statistical data. SmartPLS was chosen as a test tool, because the sample used is not too large, and the hypothesis is made in the form of predictions. The results of this study indicate that the work environment has a significant influence on the variable job satisfaction, work motivation has an influence on job satisfaction, work motivation has an influence on Organizational Citizenship Behavior, work motivation has an influence on Organizational Citizenship Behavior, and the work environment has no influence on Organizational Citizenship Behavior. Job satisfaction as an intervening variable from the work environment has no effect on Organizational Citizenship Behavior. Job satisfaction as an intervening variable of motivation has a significant influence on Organizational Citizenship Behavior.

Abstract

Shipping safety is mandatory in terms of activities at sea. Recognizing the importance of safety in shipping both before sailing and during sailing, this is because safety is the main goal in transporting and in working, the attention of all parties is always safety as the main goal. This study aims to assess the level of knowledge of fishermen about shipping safety, whether they work as fish catchers or in the field of sea transportation. The sample used is 50 fishermen who are in the city of Cilacap. The research method used is quantitative by giving a questionnaire and then assessing the level of knowledge. The results showed that the category was sufficient and good, namely 20 people or 40% and at least in the less category, namely 10 people or 20%, this shows that the average level of knowledge of fishermen about shipping safety. To increase knowledge, socialization and training are needed. Increasing knowledge can be done by socialization through mass media and training carried out regularly by the government and other non-governmental organizations.

Abstract

Generalization and symbolic manipulation are fundamental components of algebraic thinking. Generalization is often regarded as the core of mathematics and a defining characteristic of problem solving. Consequently, the use of problem-solving contexts has strong potential to enhance and develop individuals’ algebraic thinking skills. Both algebraic thinking and problem solving play a crucial role in determining success in solving mathematical problems. To examine research trends in these areas, a bibliometric analysis was employed within a systematic mapping study by reviewing documents indexed in the Scopus database. The results indicate that between 2001 and 2021, only 35 Scopus-indexed articles explicitly addressed algebraic thinking and problem solving. This study aims to fill gaps in the state of the art by conducting a bibliometric review of these 35 articles. The findings reveal that algebraic thinking and problem solving remain prominent and relevant research topics in mathematics education. However, word cloud analysis shows that the term belief appears in relatively small proportions, while self-efficacy has not yet emerged within the thematic networks or research trends related to algebraic thinking and problem solving. Moreover, studies integrating algebraic thinking, problem solving, scaffolding, and self-efficacy are still limited. Research focusing on student participants and mathematical content within the maritime domain is also scarce. Therefore, a promising direction for future research is to explore algebraic thinking processes through problem-solving scaffolding based on levels of self-efficacy among maritime students.
