Abstract

The use of various modes of transportation in transporting goods and passengers certainly presents each advantage. However, transporting logistics by land has various negative impacts such as pollution, congestion, and excessive dependence on land transportation [19]. The use of land transportation modes also has an impact on the high cost per kilometer with the same distance traveled. The use of inland waterways as a mode of logistics transportation has increased in recent years especially in Europe and Asia, of course this is driven by the benefits offered. The main objective of this study is to analyze and compare the effectiveness of sustainable logistics using inland waterway modes, especially in the context of cost, operational efficiency, and environmental impact. This research aims to provide an in-depth insight into the potential benefits and challenges faced in implementing an inland waterway-based logistics system. The method used to find data and information is to use the literature study method that discusses the use of inland waterways. From the results of the studies collected and analyzed, it was found that Inland Waterway has many positive impacts and greater benefits when compared to using other transportation routes. In addition, the application of Inland Waterway has succeeded in reducing air pollution levels, reducing shipping costs, and as the most environmentally friendly branch of water transportation.

Abstract

This study was motivated by the low level of understanding among sixth-grade students of the material on the events leading up to the Proclamation of Indonesian Independence in the Social Sciences subject, particularly in terms of remembering the sequence of events and important figures. This condition has an impact on the low learning outcomes of students. This study aims to improve learning outcomes through the application of the Jigsaw learning model assisted by Google Sites media. The method used was Classroom Action Research, which was carried out in two cycles, consisting of the planning, implementation, observation, and reflection stages. Data were collected through learning outcome tests and observation of student activities during learning. The results showed an increase in student understanding after the action was implemented. In cycle I, the average student score was 70, and there were still students in the low category. After improvements were made in cycle II through simplification of the material and optimization of Google Sites media, all students achieved a sufficient to very high category, with the average score increasing to 78.76. The integration of the Jigsaw model and digital media made learning more interactive, focused, and easier for students to understand. Thus, the use of the Jigsaw model assisted by Google Sites is effective in improving student learning outcomes in social studies material in elementary school.
