Worldwide trade is conducted 80% through maritime routes, including the export and import of coal. Coal is a non-renewable energy source, often used as fuel for power plants. As technology advances, detecting metal contaminants in coal cargo becomes crucial to prevent contamination of coal with metal materials. This study aims to (1) understand the operation of a conveyor in transporting coal, and (2) assess how the Proximity inductive sensor detects metal presence. The methods used in this research include real data analysis and literature review, conducted aboard the ship. The researcher designed and developed a prototype system for this purpose. The Proximity inductive sensor is utilized to detect metal contaminants, such as aluminum, iron, and stainless steel, among the coal cargo. The research was carried out during sea practice (prola) aboard the WHS ISKANDAR 1. The findings indicate that the conveyor is driven by a DC motor, and the Proximity inductive sensor effectively detects metals to separate them from the coal cargo, thus purifying the coal from metal contaminants.

This study is a Classroom Action Research (CAR) aimed at improving the understanding of multiplication concepts among Grade II A students of SD N Koroulon 2 Sleman through a Deep Learning approach assisted by coin-based media. The research was conducted in two cycles using the spiral model developed by Kemmis and McTaggart. In the Cycle I, the learning process focused on using coin games as a concrete medium to build conceptual understanding of multiplication. The results showed that only 68% of students achieved learning mastery. Discrepancies were still observed in the achievement indicators, particularly in converting repeated addition into multiplication sentences. Based on the reflection results, improvements were implemented in the Cycle II through strategies such as paired group work, varied learning activities, and the inclusion of a "semi-abstract" stage in the instructional process. The results of the second cycle showed a significant improvement: learning mastery reached 89%, and all learning achievement indicators exceeded 80%. This study demonstrates that the Deep Learning approach, supported by contextual media and adaptive teaching strategies, can meaningfully enhance students' conceptual understanding of multiplication. This success was also supported by effective classroom communication and the cultivation of reflective thinking habits throughout the learning process.

Abstract: Bedhaya is a dance genre that lives and develops in Javanese society. This dance is a legacy of the times of the Hindu Buddha. In the course of the bedhaya dance era, it changed. This article aims to reveal the changes in the dance function of bedhaya and to examine its existence in Javanese society. The research used is qualitative with a historical approach. The data collection technique used is the archival studies method. The result showed bedhaya dance derived from the dance offerings performed by devada?i. In the times of Mataram Islam, it was used to legitimize the king’s position. The Bedhaya dance had a significant role in maintaining the king's authority when the palace lost political, economic, and juridical power during colonialism. During its development, the palace was only for cultural preservation. It can be presented outside the palace walls as an art of tourism. In the modern era, Bedhaya dance is one of the references in creating contemporary dance. The change in the function of the Bedhaya dance is accompanied by changes in how it is presented, the accompanying narrative, and the essence conveyed. This shows that changes in the views and ideas of Javanese society influence its artistic creations.
