The Flaw of Tasks in EFL Textbook for Indonesian Vocational Students of Grade IX

For many decades, English teachers around the globe admitted that various tasks exposed to ESL/ EFL students help them conceptualize, practice, and master the language. Therefore, it is not surprising that many studies regarding textbook analysis have been flourished and most of them pleased the National Board of Education Standard. The current study, however, tries to analyze the tasks provided in „Forward An English‟ from a different perspective namely Higher Order Thinking Skills (HOTS) while promoting students‟ analytical and critical thinking. Thus, the book which is designed for Grade IX of Vocational School students became the object of this research. Every task in each chapter was checked, analyzed, and classified into six columns (Revised Bloom‟s Taxonomy by Krathwohl and Anderson) to determine the cognitive level and types of a task as well. Based on 199 item tasks collected in the whole chapters, it was found out that the author presented the tasks in the following order: understanding, application, remembering, while evaluation and creation occupied the least. Moreover, the tasks are found to be mainly in the lower level, few in the middle level, and less in the higher level of the cognitive domain. It can be concluded then that the textbook does not promote students‟ creative and critical thinking skills. Relying on these data, one will not be surprised to witness that many Vocational students played around while working on the assignments

Optimasi Penentuan Elevasi dan Azimuth Peluncur Roket Menggunakan Pid

Optimasi penentuan Elevasi dan Azimuth Peluncur Roket Menggunakan PID akan membahas mengenai teori dasar yang melandasi permasalahan dan penyelesaian dalam rancang bangun Optimasi penentuan Elevasi dan Azimuth Peluncur Roket Menggunakan PID. Alat yang akan dibuat menggunakan sistem mikrokontroler Arduino mega 2560 untuk mengendalikan launcher roket. Dari sistem yang direncanakan, mikrokontroler Arduino mega 2560 berfungsi sebagai pengolah data, apabila mikrokontroler menerima masukan data dari keypad maka mikrokontroler akan bekerja mengolah data inputan dan akan mengirim data berbentuk PWM ke driver motor, sehingga motor memutar dan menggerakkan louncher roket. data keluaran dari sensor berguna untuk mendeteksi koordinat posisi sudut azimuth maupun koordinat posisi sudut elevasi sasaran pada setpoint awal. Driver motor bekerja untuk menggerakkan motor arah posisi sudut azimuth maupun posisi sudut elevasi sasaran yang diinginkan
