Abstract

The objective of this research is to investigate the fuel consumption and exhaust emission of Motorcycle Honda Supra X 125 assembled in 2007 with the use of intake manifold with base material ofpineapple leaf composites. This research used the experimental method. Its sample was Motorcycle Honda Supra X 125 assembled in 2007 with Machine Number: JB51E1951246. The sample of research was taken by using the purposive sampling technique. The data of research were gathered through experimental method. The fuel consumption was measured in a static condition with measuring cup. The testing was done by measuring the time required by the machine to spend fuel in a certain volume at the low, medium, and high machine revolutions. The measurement of exhaust emission of carbon monoxide (CO) and hydrocarbon (HC) used the gas analyzer of Type 898 OTC STARGAS Global Diagnostic, which was conducted according to SNI 09-7118.3-2005 regarding Procedure for Testing Motor Vehicle with L category in idle condition. The data of research were analyzed by using the descriptive comparative technique of analysis. The results of research show that the average fuel consumption in the use of standard intake manifold at the machine revolutions of 1.200 rpm, 2.500 rpm, and 4.000 rpm is 0.088256 ml/second. Meanwhile the average fuel consumption in the use of intake manifold with pineapple leaf fiber composites at the machine revolutions of 1.200 rpm, 2.500 rpm, and 4.000 rpm is 0.072183 ml/second. Thus, the average fuel consumption in the use of intake manifold with pineapple leaf fiber composites decreases up to 20.7%. In addition, the average exhaust emission of CO in the use of standard intake manifold is 1.838%. Meanwhile, the average exhaust emission of CO in the use of intake manifold with pineapple leaf fiber composites is 1.127%. Accordingly, the average exhaust emission of CO in the use of intake manifold with pineapple leaf fiber composites decreases up to 38.7%. Furthermore, the average exhaust emission of HC in the use of standard intake manifold is 1.178 ppm. Meanwhile, the average exhaust emission of HC in the use of intake manifold with pineapple leaf fiber composites is 1.141 ppm. Therefore, the average exhaust emission of HC in the use of intake manifold with pineapple leaf fiber composites decreases up to 3.1%.

Abstract

Jobsheet adalah suatu prosedur kerja praktek yang berbentuk lembaran-lembaran. Jobsheet merupakan salah satu sumber belajar yang penting dalam pembelajaran praktik. Penelitian ini bertujuan untuk mengembangkan jobsheet Alat dan Pengukuran Teknik dan mengetahui kelayakan jobsheet yang dikembangkan. Jenis penelitian ini adalah penelitian dan pengembangan. Langkah-langkah penelitian dan pengembangan terdiri dari Define, Design, Development and Dissemination. Subyek penelitian adalah mahasiswa Pendidikan Teknik Otomotif yang mengikuti perkuliahan Alat dan Pengukuran Teknik sebanyak 20 mahasiswa. Hasil penelitian menunjukkan persentase kelayakan aspek penyajian materi pada jobsheet sebesar 83,75%. Persentase kelayakan aspek kebahasaan pada jobsheet sebesar 81,87%. Persentase kelayakan aspek kegrafikan pada jobsheet sebesar 82, 91%. Persentase kelayakan aspek manfaat pada jobsheet sebesar 88,75%. Persentase kelayakan keseluruhan jobsheet sebesar 84,47%. Kesimpulan dalam penelitian ini adalah jobsheet yang dikembangkan layak untuk digunakan dalam pembelajaran praktik mata kuliah Alat dan Pengukuran Teknik.

Abstract

Unemployment rates producing by vocational high school (VHS) is still high. To overcome this problem, it is necessary to develop an entrepreneurship learning model in accordance with students’ skills. This study aims to: (1) develop project-based entrepreneurship learning media integrated with productive practical learning in VHSs; (2) design project-based entrepreneurship learning integrated with productive practical learning which had the criteria of validation, effectiveness, and practicability. The research procedures consisted of analysis, design, development, implementation, and evaluation (ADDIE) model. The product of the learning model development was validated by experts. The subjects of the research involved eleventh grade students of automotive engineering study program in the second semester, entrepreneurship teachers and automotive engineering teachers in VHSs. The products of the study consisted of: (1) a guided learning book and learning media (lesson plans and learning assessments); (2) the teachers’ and students’ positive and objective responses toward the implementation of the learning model which was proved by their comments that the developed learning model fulfilled the criteria of validation, effectiveness, and practicability to be implemented in VHSs.
