Abstract

The study in Aerodynamics has shifted from large theoretical curriculum into authentic learning experiences in response to the industry requirement. In addition, the development of computational methods has revolutionized the design cycle in aerodynamics. This work describes an integrated approach in an undergraduate Aerodynamics course using the Kolb’s Learning cycle. Experiential learning is incorporated in the class to provide more opportunities for students to understand the theoretical concept through experiencing the applications and impact of the concept in real life. The Finite Element Method (FEM) which is widely used in analyzing many engineering problems was integrated into the Aerodynamics theory and application to visualize changes of parameter in the design phase.  The main learning objective of the developed learning module is to apply appropriate aerodynamics models to predict the forces on and performance of a vehicle design. The module is assessed by instructor before being applied for the students in the classroom. It is considered to be an effective method for learning when lectures and computation works are integrated in a meaningful manner.   This development research is expected to be able to produce graduates who are competent in the field of design.

Abstract

Entrepreneurship is one aspect that affects economic growth in Iindonesia. Students are the next generation who are expected to be able to create entrepreneurs in the future. The purpose of this research is to analyze entrepreneurial interest based on vocational education level in mechanical engineering and the factors driving this interest. This research uses a mix-method that combines a quantitative approach and a qualitative approach. The subjects of the research were Class XII students of State 2 Vocational High School in Surakarta, department of mechanical engineering, totaling 120 people and D3 Mechanical Engineering students at Sebelas Maret University, totaling 57 people. Data collection techniques to determine the entrepreneurial interest of students (quantitative data) using the questionnaire method while knowing the factors that influence entrepreneurial interest (qualitative data) using the interview method. Analysis of data for quantitative data using descriptive analysis and for qualitative data using thematic analysis. The result showed that the majority of students wanted to be entrepreneurs but a different levels of time. Factors that influence entrepreneurial interest are divided into two, namely internal factors and external factors. The internal factors driving entrepreneurial interest are motivation that comes from the individual’s self and enthusiasm to face risk challenges. External factors driving or family, entrepreneurial interest are motivation the arises due to the influence of friends or family, entrepreneurial experience and entrepreneurship education.

Abstract

Evaluation of the performance of study program graduates in the world of work is one indicator of higher education quality. The high performance of graduates and their relevance to the needs of the world of work indicate a good quality higher education. The purpose of this study is to evaluate the performance of graduates of Sebelas Maret University Mechanical Engineering Education (PTM UNS) in the world of work. So that the results obtained as a priority reference for learning development in study programs and students. This research is quantitative descriptive. It is carried out through a tracer study of graduate data and a survey of graduate users. The subjects of this research include UNS PTM graduates who graduated in 2016, 2017 and 2018 as a source of tracking data for graduates and 80 graduate users as a source of satisfaction survey data and the level of importance of the formulated Graduate Learning Outcomes (CPL). Data collection techniques were carried out through the method of filling out the questionnaire instrument questionnaire. The analysis was carried out using quantitative descriptive statistical analysis techniques using the SPSS V.21 data processing application. The results of this study show profile data for PTM UNS graduates, namely the average graduate with a very satisfactory predicate (GPA 3.46) with an average study period of 4 years and 2 months. Most (56%) work as educators, with a high level of suitability of work with the field of science 47.5%; 38.9% moderate and the remaining 13.6% low. The average waiting time for the first job after graduation is less than 6 months (76.5%). Furthermore, for the results of the graduate user satisfaction survey, the average total satisfaction is 4.28 (very satisfactory). With an importance level of 12 Graduate Learning Outcomes (CPL), 11 of them are in the very important category and one is in the important category (T8). Objectively, users are satisfied with the performance of graduates, but subjectively researchers need to propose development priorities for study programs based on the value of the level of satisfaction which is below the total average value. The conclusion in this study shows that the performance of graduates of the PTM UNS study program has been good or satisfactory. However, there is a need for a program to improve the quality of graduate performance in the communication and professional aspects. It is hoped that the study program will be able to improve the quality of these two aspects through improving the quality of learning, infrastructure and learning facilities as well as improving the quality of educators/lecturers.

Abstract

Mobile learning has become a great tool for delivering educational resources in which learners can not only access the module anytime and anywhere, but also can actively interact with the learning material. This research aims to design and develop learning material of an automotive engineering course based on mobile device for mechanical engineering education students. The development e-publication module of motorcycle mechanic course employed the ADDIE instructional design model encompassing five steps: analysis, design, development, implementation, and evaluation. The student’s learning style was identified to characterize mobile module target. It was found that majority of the students as user have auditory and kinesthetic, then the module will be designed with the design in accordance with auditory and kinesthetic learning style, therefore the module will be mainly designed on audio-based format. The learning module developed using e-publication software consisting of structured documents combined with audio and video files. Some experts were asked to evaluate the implementation feasibility of the module. The average evaluation score was 85.4%, indicating high acceptance of implementing the learning module. It implies that e-publication module delivery has the potential to gain wider acceptance in engineering education complementing the in-class and practical learning.

Abstract

Abstract. The main objective of this study was to analyze the effect of Natural Weathering on the tensile strength and microstructure of recycled polypropylene (rPP) composites with bamboo fiber reinforcement. The rPP-bamboo composite specimens were made using extrusion molding and injection molding machines. The weight fraction used in making the specimens was 10% bamboo fiber and 90% rPP. The rPP-bamboo samples were tested with 3 variations of exposure time, 0 months (without exposure), 1 month and 2 months according to ASTM D1435-05 standard. From the 3 variations of exposure, a tensile test was carried out with the ASTM D638 type V standard to evaluate the value of tensile strength, modulus of elasticity and elongation. Then SEM (Scanning Microscopy Electrone) was performed to see the microstructure of the composite. The results showed that the tensile strength at exposure time of 0 months, 1 month and 2 months was 18.1 MPa with an elongation of 5%, 19.5 MPa with an elongation of 6.4% and 19.3 MPa with an elongation of 6.6%. Young's modulus values showed a decrease with increasing exposure time, ranging from 222 MPa in the sample without exposure to 141 MPa at an exposure time of 2 months. With SEM it is known that, the microstructure of the composite at the beginning of exposure shows a strong bond between the fiber-matrix even though there are some voids in the specimen. At 2 months of exposure, it was seen that there was a gap between the matrix and bamboo due to the hydrophilic nature of bamboo fiber.
