Abstract

The aerofoils are used to get the lifting force on the design of plane's wings. The lifting force is caused by difference air velocity on upper and lower aerofoil which the magnitude depend on attack angle of aerofoil and air velocity exist surrounding. This experiment aims to show the force vector (pressure distribute) on the aerofoil. The aerofoil is attached by air with konstant velocity. The research procedure is done by change the attack angle of aerofoil on five formation. The surface of aerofoil is connected with pressure gage which disperse at 11 point of measurement. The result shows that magnitude of force vector is depended on attack angle of aerofoil. Increasing angle of aerofoil until boundary angle will be followed by increasing air velocity on the point of measurement and finally increase force vector. Upper boundary angle will be followed by decreasing air velocity and finally decrease force vector.Aerofoil digunakan untuk mendapatkan gaya angkat pada desain sayap pesawat. Gaya angkat disebabkan oleh perbedaan kecepatan udara pada aerofoil atas dan bawah yang besarnya tergantung pada sudut serang aerofoil dan kecepatan udara yang ada disekitarnya. Eksperimen ini bertujuan untuk menampilkan vektor gaya (distribusi tekanan) pada aerofoil. Aerofoil dilekatkan pada udara dengan kecepatan konstan. Prosedur penelitian dilakukan dengan cara mengubah sudut serang aerofoil pada lima formasi. Permukaan aerofoil dihubungkan dengan alat ukur tekanan yang tersebar pada 11 titik pengukuran. Hasil menunjukkan bahwa besarnya vektor gaya bergantung pada sudut serang aerofoil. Sudut aerofoil yang meningkat hingga sudut batas akan diikuti dengan peningkatan kecepatan udara pada titik pengukuran dan akhirnya meningkatkan vektor gaya. Sudut batas atas akan diikuti oleh penurunan kecepatan udara pada titik pengukuran dan akhirnya menurunkan vektor gaya.

Abstract

The aims of this research is to describe the strategies used in integrating soft skills, obstacles encountered in the application of soft skills, and efforts to overcome the obstacles. This research is a descriptive research. The research subjects are 7 welding practice teachers and 60 students. Data were collected by means of survey, interview, observation and documentation. The results show that soft skills have been integrated in welding practice learning by incorporating it into the lesson plan (RPP). By scientific approach and discussion method, the soft skills values are included in the assessment's rubric. Obstacles in the integration of soft skills are the lack of students concern regarding soft skills, less motivated students, limited time in the integration of soft skills, and different perception among the teachers in applying soft skills. Efforts by the teachers to overcome the obstacles are by warnings, rewards, punishment, and establish a cooperation with other party.Penelitian ini bertujuan untuk mendeskripsikan strategi yang digunakan dalam mengintegrasikan soft skills, hambatan yang dihadapi dalam penerapan soft skills, dan upaya dalam mengatasi hambatan tersebut. Penelitian ini merupakan penelitian deskriptif. Informan penelitian yaitu guru praktik pengelasan 7 orang dan 60 siswa. Teknik pengumpulan data yaitu survei, wawancara, observasi dan dokumentasi. Hasil penelitian menunjukkan bahwa soft skills dalam pembelajaran praktik pengelasan telah diintegrasikan dengan memasukkan ke dalam rencana pelaksanaan pembelajaran (RPP). Dengan pendekatan saintifik dan metode diskusi, nilai soft skills dimasukkan ke dalam rubrik penilaian. Hambatan dalam mengintegrasikan soft skill, siswa kurang peduli terhadap soft skils, siswa kurang termotivasi, terbatasnya waktu untuk menanamkan soft skills, dan perbedaan persepsi guru dalam menerapkan soft skills. Upaya yang dilakukan guru untuk mengatasi hambatan dengan memberikan teguran, reward, punishment, dan menjalin kerjasama dengan pihak lain.

Abstract

The study aimed to identify the students who cannot finish their course on time, addressing the inhibiting factor for their course completion, identify the students' efforts and struggle on their course completion, and to understand their expectations from the school administration to accommodate their course completion. The research used survey methods with questionnaire as the instrument. The subjects of the research are the diploma and bachelor degree students of Mechanical Engineering Education Department. Data were analyzed using quantitative-descriptive technique. The results show that the inhibiting factors are the long commute to campus for supervisions, many students still taking coursework, students already have a job, passive supervisors, unconducive environment, and supervisions that were not intensively done. The students were still committed to complete their course, albeit those inhibiting factors. Students' commitments were supported by various efforts, namely intensive supervision, independent study or discussion, and finding a conducive environment to work on their final projects and theses. Students' expectations for the success of their course are the availability of final project and thesis in an earlier stage of their study, supervisor should be appointed based on their competency, increasing the allocated time of the final project schedule, the administration needs to renew the workshop's machinery and equipment, and cut off the unnecessary final project and Thesis administration steps, to make it easier for students in completing their course. Tujuan penelitian adalah untuk mengidentifikasi mahasiswa yang tidak dapat menyelesaikan studinya tepat waktu, mengetahui faktor penghambat, mengetahui usaha-usaha yang sudah dilakukan mahasiswa, dan mengetahui harapan mahasiswa kepada pengelola Jurusan Pendidikan Teknik Mesin FT UNY. Penelitian menggunakan metode survey menggunakan angket dengan analisis deskriptif kuantitatif. Objek penelitian yaitu mahasiswa D3 Teknik Mesin dan S1 Pendidikan Teknik Mesin. Hasil penelitian menunjukkan terdapat beberapa kendala penyelesaian studi yaitu: jarak yang jauh ke kampus untuk bimbingan, masih ada yang kuliah teori/praktik, sudah ada yang bekerja, dosen kurang aktif membimbing, lingkungan tempat tinggal kurang kondusif, dan bimbingan tidak intensif. Namun demikian, mahasiswa masih berkomitmen untuk menyelesaikan studinya. Keseriusan mahasiswa tersebut didukung dengan berbagai usaha, seperti bimbingan secara intensif, belajar mandiri atau diskusi, dan mencari lingkungan yang kondusif untuk mengerjakan Proyek Akhir dan Skripsi. Selain itu, harapan mahasiswa yaitu mata kuliah Proyek Akhir dan Skripsi dapat diambil lebih awal, penentuan dosen pengampu mata kuliah relevan dengan kompetensinya, jadwal pelaksanaan Proyek Akhir perlu ditambah frekwensinya, peremajakan peralatan bengkel, dan memperpendek administrasi Proyek Akhir dan Skripsi sehingga semakin mempermudah mahasiswa menyelesaikan studinya.
