PENGEMBANGAN MEDIA PEMBELAJARAN CNC BERBASIS PERANGKAT LUNAK ANIMASI

<p><em>This research aims to (1) develop an instructional material based animation software for CNC course, (2) evaluate instructional material for CNC course that has been developed. The research was conducted at the Department of Mechanical Engineering Education, </em><em>Faculty of Teacher Training and Education, </em><em>Sebelas Maret University Surakarta. This research used Multimedia Development Life Cycle (MDLC) as research procedure, which consists</em><em> </em><em>of six stages, concept, design, collecting material, assembly, testing and distribution. Evaluation of instructional material for CNC course was performed by ask potential users to operate CNC instructional material that have been developed, then get response from potential users through a questionnaire. Potential users are divided into two categories, lecturers of CNC and CAM courses and students of Mechanical Engineering Education who take CNC and CAM courses in the academic year 2015/2016. Questionnaire for lecturers of CNC and CAM course reviewing instructional material from aspects of learning content, interaction, and presentation of the material. The questionnaire was given to 3 lecturers consisting of 15 point statements with Rating Scale as assessment system on intervals 1-5. Questionnaire for student reviewing instructional material from aspect of learning motivation as one of instructional material function. Questionnaire was given to 26 students consisting of 20 point statements with Likert Scale as assessment system on intervals1-5. The results of the research show (1) the development of instructional material for CNC course used Adobe Flash CS6 as main software with MDLC as development pro</em><em>c</em><em>edure, (2) the evaluation results show the instructional material for CNC course that developed gets (a) in aspects of learning content, interaction, and presentation of the material, the instructional material for CNC course gets very good category with percentage 90,22%, (b) in the aspect of learning motivation as one of instructional material function, the instructional material for CNC course gets good categories with percentage 78,39%.</em></p>

IMPLEMENTATION OF PROJECT BASED LEARNING MODEL FOR IMPROVING STUDENTS LEARNING OUTCOMES OF ADVANCED MACHINING ENGINEERING IN UNIVERSITAS SARJANAWIYATA TAMANSISWA

This research was conducted to improve learning outcomes through project-based learning model in the course of advanced machining in the department of Mechanical Engineering Education. This research was motivated by the low students learning outcomes in the advanced machining course, whereas the results of the study subjects was the vital thing for the students who will have production expertise. The research method was Classroom Action Research (CAR) with Kemmis and Mc Taggart model, by pointing in cycle, and consists of four stages: planning, implementation, observation, and reflection. Subjects were student of Mechanical Engineering Education production option that follows the advanced machining course for academic year 2014/2015. Data were collected by instruments such as observation sheet during the action takes place, the observation sheet practical activities for learning outcomes. Data was analyzed using quantitative descriptive. Project Based Learning (PjBL) model can improve learning outcomes in affective and psychomotor abilities of students. The increase in affective reaches 9.41 and psychomotor abilities enhancement from the first cycle to the second cycle reaches 6.6.

Characters-Based Collaborative Learning Model: Its Impacts on Students' Attitude and Achievement

This study determined the impacts of the implementation of characters-based collaborative learning model on the students’ attitudes and achievement in the course of machining process. This experimental study was conducted in the fitting and machining workshop at the Department of Mechanical Engineering Education, Faculty of Engineering, Universitas Negeri Yogyakarta. The population consisted of the students who were taking the course of Complex Machining Process totaling 85 students. The samples included 33 students who were determined by purposive sampling technique. The experiment was carried out by the posttest-only control design. The instrument validation was conducted by expert judgment. The data in this study were analyzed using descriptive analysis and t-test with significance level of 0.05. The results revealed that: (1) the attitude of the students in the model class was better than the conventional class, and (2) the students of the model class performed better achievement in the course of Machining Process.

Simulasi Pengembangan Bengkel Fabrikasi Jurusan Pendidikan Teknik Mesin Sesuai Kaidah 5S Menggunakan Aplikasi 3ds Max

The objectives of this study were to assess the risks involved in workshops, to apply the Seiso, Seiton, Seiri, Seiketsu, Shitsuke ( 5S) concept for workshops development and to develop the fabrication workshop for the Department of Mechanical Engineering Education, Faculty of Engineering, YSU using the 3DS Max simulation application. This study was categorised into Research and Development. The first steps were designing and creating the product using 3DS Max application. The next step was testing the product by implementing it to perform the workshops policy. The results of this study showed the risks consisted of noise, strong light, harmful gases and the mechanical hazards due to falling and moving objects. The implementation of 5S concept, K3 and ergonomics were required to maintain the regularity, efficiency and work discipline, to prevent and to minimize workplace accidents. The development of fabrication workshops using the 3DS Max simulation applicationis is beneficial for implementing the aspects of 5S, K3, ergonomics and provides a reference in redesigning a workshop.

Kemampuan Mahasiswa dalam Memilih Material pada Pembuatan Karya Teknologi

The objectivesof this study w ere to analyze the approaches applied by the studentstodetermine the type of materials, to examine the type of materials widely used by the students, and to assess the students’ accuracy in determining the type of materialsto produce technological works. This study was categorised into ex post facto study conducted at the Department of Mechanical Engineering Education, Faculty of Engineering, YSU. The samples were 139 students with39 units of machines. The data was obtained using documentation by examining the reports and the surveysof the developed technological works. The data was analysed descriptively. The results showed the students havethe ability to consider the criteria of materials selection based on materials science, including strength, usage, fabrication, availability and prices. The type of materials widely used is metal as follows: carbon steel, alloy steel, cast iron, stainlesssteel, aluminum and copper. The carbon steel is the most widely used material utilized by 62% of the students.There was36%of the components developed usinginaaccurately selected materials.

Pre-Test pan Work Plan sebagai Strategi Pembelajaran Efektif pada Praktikum Bahan Teknik Lanjut Jurusan Pendidikan Teknik Mesin FT UNY

To find the most effective learning strategy for the practicum in the laboratory of materials of the department of Mechanical Engineering Education, Faculty of Engineering, Yogyakarta State University (YSU), a study that aims to determine the effect of applying pre-test and work plan on the learning activities and the achievement of students in the laboratory was conducted. This action research used the purposive random sampling technique. Pre-test and work plan were conducted as the treatment. The data of study was collected through a test to analyse the students’ achievement scores, then they were analyzed using t-test with SPSS. The results of this study indicated that the application of pre-test and work plan in addition to the standard module was proven to be more effective than the normative learning using the module with t = 3.055 p = 0.003 <0.05. The implementation of the pre-test and work plan in addition to the use of standard modules is able to improve the students’ motivation, independence and readiness to learn as well as the cooperation among the students, therefore the achievement is also improved. The mastery of competencies increased significantly proved by the increasing values of mode 66 to 85 (the experiment), and mean 73.12 into 79.32 (experiment).
