Abstract

Practical-based learning can improve students' thinking skills and abilities. Optimizing the implementation of the practicum needs to be supported by various factors so that student learning outcomes are good. This study aims to obtain the dominant factors that support the implementation of student practicum on lathe work. This study uses descriptive quantitative methods with data collection techniques using a questionnaire instrument. The research population is students from the Mechanical Engineering Education Study Program at a university in Bandung. The results of the study indicate that there is a relationship between a number of independent variables. The six independent variables identified as sources of practicum support were then grouped into two new factors. The two factors have a correlation greater than 0,5, so it can be concluded that it is feasible to summarize the six variables analyzed. Based on the total variance score explained, factor 1 is the dominant factor affecting the implementation of the lathe work practicum and according to the rotated component matrix it is known that from factor 1, the workshop building variable has the highest correlation and the tools and practicum materials have the second highest correlation. This shows that the variables of the workshop building and the variables of tools and practicum materials are very important to be used as references in supporting good learning outcomes in practical activities.

Abstract

Energy needs continue to increase from year to year in line with population growth in Indonesia. Therefore, wind turbines as a renewable alternative energy source to meet the energy needs of coastal communities. The use of heavy and high ice blocks has always been a problem for fishermen in fish catches, this has an impact on the quality of the fish caught. This thermoelectric coolbox with wind power plant is designed by combining the components of a thermoelectric coolbox and a wind turbine which functions to maintain the temperature in the coolbox so that the fish stored are more durable using electricity generated from the rotation of the wind turbine. This research uses the design and development (D&D) method and is supported by secondary data from published articles and news journals which aim to design a three-dimensional model of a thermoelectric coolbox using solidworks software. The results of the design analysis obtained turbine area, turbine height, chord length, torque value, shaft diameter and allowable shear stress. With the results of the analysis of the design of a thermoelectric coolbox with a wind turbine, it has the potential and benefits for the fishing profession and can be realized into a product.
