Abstract

Container terminals are critical nodes in global trade, where productivity hinges on the efficiency of handling equipment like container cranes. At PT. Kaltim Kariangau, a terminal jointly managed by PT. Pelindo and the East Kalimantan provincial government, operational challenges persist despite infrastructure enhancements. In 2023, an additional crane was introduced to the terminal, increasing the total to three. However, issues such as prolonged idle times and equipment malfunctions adversely impacted crane efficiency. This research evaluates crane performance using BCH (Box/Crane/Hour) and BSH (Box/Ship/Hour) metrics to assess their effect on loading and unloading productivity. The analysis reveals that in 2023, the average crane performance was 27 boxes/hour, a level classified as good. Paradoxically, overall productivity declined post-crane addition compared to prior operations. Using regression analysis, the study identifies a strong positive correlation (R = 0.7316) between crane performance and terminal productivity, with a coefficient of determination (R²) indicating that crane efficiency accounts for 54% of productivity variations. The findings highlight that improved crane performance directly enhances operational output, where each unit increase in BCH corresponds to a 1.809-unit rise in productivity. Hypothesis testing confirms that crane performance significantly influences loading and unloading efficiency. These results underscore the need for effective equipment utilization and maintenance strategies to optimize terminal operations. The research concludes that while infrastructure upgrades are essential, addressing operational inefficiencies is critical to achieving sustainable productivity improvements.

Abstract

Particularly in multicultural classrooms like those in Indonesia, culturally responsive teaching (CRT) provides inclusive practices that serve a variety of learners. With an emphasis on positive and negative answers across four aspects: experience, attitude, feeling, and belief, this research investigates students' perceptions of culturally responsive teaching implementation in an English-speaking class at Universitas Muslim Indonesia’s English Education Department. A qualitative case study design was used to gather information from 12 students using field notes, observations, interviews, and documentation. Miles and Huberman's interactive model was used in the analysis. According to the findings, most students thought culturally responsive teaching improved their motivation, cultural sensitivity, and involvement in class. Due to emotional discomfort or a lack of knowledge of artistic content, some students did, however, express fear and limited engagement. The research emphasizes how culturally responsive teaching may be both powerful and challenging for some people and contributes to improving it for consistent, emotionally inclusive teaching methods. In theory, this research advances culturally responsive teaching in higher education; in practice, it gives lecturers guidance on how to create speaking exercises that are inclusive of all cultures while addressing their students' anxiety and engagement issues. The findings suggest that higher education institutions should integrate Culturally responsive teaching (CRT) as a core component of teacher training and curriculum development, particularly in English language education. Lecturers need continuous professional development to effectively design and facilitate culturally inclusive speaking activities that reflect students’ diverse backgrounds, mitigate anxiety, and foster meaningful engagement. Institutional policies must support culturally responsive pedagogy by encouraging reflective teaching practices, developing culturally rich teaching materials, and creating safe classroom environments where emotional discomfort can be addressed constructively. Future studies are recommended to examine CRT in larger and more diverse populations and to explore the impact of specific CRT strategies on different language competencies beyond speaking.
