Abstract

Penelitian  ini  bertujuan  untuk mengetahui  peningkatan  pemahaman mahasiswa  setelah  pembelajaran mempergunakan media peragatentang sistem pengisian pada sepeda motor pada mata kuliah Perakitan Otomotif I mahasiswa Teknik Mesin Universitas Negeri Semarang  tahun 2009/2010.Penelitian mempergunakan desain eks‐perimen  semu/Quasi Eksperiment Desaindengan  pola  pre  test­post  test  one  group  design. Populasi  penelitian  ini adalah mahasiswa yang mengambil mata kuliahPerakitan Otomotif  I  Jurusan Teknik Mesin Universitas Negeri Se‐marang yang  terdiri dari 68 mahasiswa rombongan belajar blok,karena sempel penelitian hanya satu kelas maka yang diambil adalah pada kelas blok rombel 2 yang terdiri dari 29 mahasiswa dari seluruh populasinya. Berdasar‐kan hasil dari analisis data bahwa ada peningkatan antara hasil belajar tentang sistem pengisian pada sepeda mo‐tor sebelum dan setelah menggunakan media peraga pada matakuliah perakitan otomotif I. Hal itu terlihat pada ha‐sil nilai rata‐rata sebelum menggunakan media peraga(pre test) sebesar 55,034 dan nilai rata‐rata setelah menggu‐nakan media peraga  (post  test)  sebesar 66,10,sehingga dapat dikatakan bahwa penggunaan media  peraga  sistem pengisian pada sepeda motor telah berjalan dengan baik karena prestasi belajar mahasiswa yang mengikuti perku‐liahan PerakitanOtomotif II mengalami peningkatan 20,10 % dari sebelum menggunakan media peraga sistem keli‐strikan pada sepeda motor.Kata kunci: sistem pengisian, sepeda motor This research was conducted to identify the  improvement of students’ understandings after  learning by using figure media about motorcycle charging system in Automotive Assembly I subject at Mechanical Engineering Department, Semarang State University year 2009/2010. The research used quasi‐experiment design with pre test­post test one group design. The population of it was students who took Automotive Assembly I subject at Mechanical Engineering Department,  Semarang  State University  consisting of 68  students  in block  study  group. Because  the population of this research was just from one class, the sample was then 29 students taken from the mentioned population. According to the data analysis result, there is difference of study result of motorcycle charging system before and after using the figure media in Automotive Assembly I subject. It is based on average score before using figure media (pre  test) about 55,034 and  the one after using  figure media (post  test) about 66,10. Hence  it can be stated  that  the use of motorcycle charging system  figure media has been applied well because the study achieve‐ments of students who joined Automotive Assembly I subject have increased about 20,10% from the achievements got before the use of figure media for motorcycle electricity system.Keywords: charging system, motorcycle

Abstract

The implementation of the Sanggul Gala learning is identical to the exploration of understanding, creativity, and imagination in order to produce a bun according to the desired theme. The limited references to books and modules, as well as the lack of Sanggul Gala learning media cause students' low understanding of the learning material. This is contrary to the factual condition, that vocational high school students in beauty study program are required to think critically and imaginatively in the Sanggul Gala learning process. The research questions of the present study are: 1) How is the development of Sanggul Gala e-Modul? and 2) how effective is the Sanggul Gala e-Modul in increasing the creativity of students in beauty study program?. The aims of this research are: 1) developing Sanggul Gala e-Modul; and 2) testing its effectiveness in increasing the creativity of beauty study program students. The research uses the RD (Research and Development) method referring to the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). The research sample was students Beauty Study Program of SMK Negeri 1 Tegal. Based on the results of the validation of learning media experts, it was found that the results of the development of the Sanggul Gala e-Module learning media had met the following criteria: 1) validity level: 81.67% (valid); 2) the level of feasibility: 3.56 (feasible), (3) the level of reliability; 0.364 (reliable). At the trial stage of the Sanggul Gala eModul and the video for students of beauty study program, it was found that the average score of students increased by 29.7% in all aspects (cognitive, affective and psychomotor). This shows that the Sanggul Gala e-Modul learning media is significant in improving the cognitive, affective and psychomotor aspects of students in beauty study program.

Abstract

There was a technology gap between industry and vocational schools. The school curricula were not following industrial needs and the educators were lack of mastery of the latest technologies according to current industry needs. The study evaluated Mitsubishi's industrial class process on students, supervisors, business, and the industrial world (DU/DI). This research applied evaluation research with a descriptive quantitative approach. The students of XII Light Automotive Vehicle who participated in the Mitsubishi industrial class of SMK Bina Utama Kendal became the participants in this research. The research subject consisted of 34 students, ten industrial teachers, and two teachers from Mitsubishi. Then, the data instruments technique applied observation, questionnaires, and documentation. The validity test adopted Product-Moment, while the reliability test used Cronbach-Alpha. The data analysis technique applied a descriptive statistical test. The result showed Mitsubishi's industrial class process toward students was sufficient, while teachers and DU/DI were declared very high.

Abstract

Tujuan penelitian ini menguji pengaruh penggunaan groundstrap dengan variasi bahan dan jumlah lilitan terhadap medan magnet pada kabel busi. Metode penelitian yang digunakan adalah eksperimen, yaitu groundstrap  dengan bahan tembaga dan aluminium berdiameter 0,80 mm dengan variasi lilitan 100, 175, dan 250 dililitkan pada kabel busi dan diuji menggunakan gaussmeter yang di dekatkan pada kabel busi keadaan mesin hidup. Hasil penelitian dianalisis dengan teknik analisis deskriptif. Hasil penelitian menunjukkan penggunaan bahan groundstrap dengan hambatan jenis rendah (tembaga) dan jumlah lilitan semakin banyak (250) lilitan pada kabel busi mampu menurunkan medan magnet paling baik dikarenakan mampu mengikat dan men-groundkan lebih maksimal. Rata-rata medan magnet kabel busi terendah dihasilkan groundstrap tembaga 250 lilitan sebesar 2,43 gauss

Abstract

The Mechanical Engineering Department of Universitas Negeri Semarang received teaching aid grantin 2012 in the form of the “MimioTeach” consisting of MimioView, MimioPad and MimioTouch. However, until now the equipment has not been used optimally due to the lack of training. ”MimioTeach” is rich in features that can simplify the interactive teaching. The objectives of community service were: 1) introducing”MimioTeach”equipment consisting of Mimio Teach, Mimio Pad, Mimio View to the Lecturers of the Mechanical EngineeringDepartment, 2) trainingthe use of such equipment to the Lecturers of the Mechanical EngineeringDepartment, and 3) assisting Lecturers in using the equipment during their teaching proceess. The method of implementation was a training to use the equipmentduring the teaching proceess of the participants. The subjects of this training weretwenty lecturersof Mechanical Engineering. The results of the activities were 16 lecturers attended the Mimio Teach training in the Mechanical Engineering Department, Universitas Negeri Semarang. Participants were introduced to Mimio devices, were trained how to use it and were guided to operate the Mimio device independently. During the training the participants enthusiastically listened to and watched the demonstration of the use of instructional tools. Participants also asked about things that did not understand. When practical activities, the participants were proven to be able to operate the Mimiodevice. However, a continuous exercise is required to be more proficient.
