Abstract

The purpose of this study to develop valid and practical Cadets Worksheets based on Problem Centered Learning. This type of research was a Research and Development (R & D) research, which uses six research steps: potential problems, information gathering, product design, design validation, design improvement, and testing. The research instrument used was a questionnaire of validity and questionnaire of practicability. Analysis techniques used to test the validity and practicality of learning materials developed student worksheet was Likert-scale analysis techniques. Based on validation data analysis by validator obtained average percentage value of Cadets Worksheet was 83,6% (very valid). The result of Cadets Worksheet practice percentage by students' was 83.4% (very practical). Based on the above data analysis can be concluded that Worksheet Physics based PCL developed valid and practical.

Abstract

STS bunkering is the activity of supplying ship fuel through the ship-to-ship method. This study aims to optimize the implementation of STS bunkering based on the STS transfer checklist. The research method used is a qualitative descriptive method with data collection techniques of field observation, interviews, and documentation studies. The results of the study show that the factors hindering the fulfillment of the STS transfer checklist consist of several factors, including: lack of supervision on duty, damage and lack of equipment, errors in cargo handling, cargo contamination, manual sounding measurements, cargo contamination by water, high waves, and strong winds. These factors are interrelated and cause disruption to the fulfillment of the STS transfer checklist standards. Efforts made to overcome these obstacles include conducting routine STS drills, maintaining and providing equipment spare parts, implementing cargo circulation methods, conducting multiple soundings, monitoring cargo, and taking weather conditions into account before bunkering. With the implementation of these efforts, it is hoped that STS bunkering can be carried out optimally based on STS transfer checklist standards.
