Diagnosis Kesulitan Belajar Siswa Pada Mata Pelajaran Sistem Operasi Kelas XMM 3 SMK Negeri 7 Samarinda Tahun Ajaran 2014/2015

Kesulitan yang dialami siswa terlihat dari hasil pengamatan pada pokok bahasan Perintah-perintah dasar sistem operasi disk operating system (DOS) . Adapun letak kesulitannya antara lain seperti, kesulitan dalam mendefinisikan pengertian Disk Operating System (DOS), kesulitan dalam mengoprasikan Disk Operating System(DOS) menggunakan aplikasi Command promt, kesulitan dalam mendefinikan fungsi perintah Disk Operating System (DOS) menggunakan aplikasi Command promt, kesulitan dalam memahami Perintah-perintah aplikasi Command promt, kesulitan dalam memahami fungsi-fungsi dari jenis perintah-perintah aplikasi command promt. Penelitian ini bersifat deskriptif kualitatif, dan dilaksanakan di SMK Negeri 7 Samarinda tahun ajaran 2014/2015 pada pembelajaran Sistem Operasi pokok bahasan Perintah-perintah dasar sistem operasi disk operating system (DOS). Subjek dalam penelitian ini adalah siswa kelas X MM 3. Kegiatan penelitian ini meliputi: Observasi/pengamatan, dokumentasi dan wawancara. Teknik analisis data menggunakan reduksi data, penyajian data dan penarikan kesimpulan. Sampel dalam penelitian ini berjumlah 12 siswa yang di peroleh dari hasil pengamatan ketika pembelajaran berlangsung.

ROSESIM: An Interactive Tool for Plant Growth Modeling

One should choose the simplest form of a model as a tool that adequately represents the processes and relationships of interest. ROSESIM was first developed in SLAM II and FORTRAN to run on a mainframe computer, where it had few users and it was cumbersome to learn and use. As use of models on a personal computer (PC) has become more popular for instruction and simulation, ROSESIM was translated first into the American Standard Code for Information Interchange (ASCII) to run in the Beginner's All-purpose Symbolic Instruction Code (BASIC) language in the popular Microsoft Disk Operating System (MS-DOS). As graphical user interface (GUI) Windows applications have gained increased popularity, ROSESIM has been translated into C++ as object-oriented programming (OOP) to run inside Microsoft Windows 3.1. This makes ROSESIM for Windows readily available to virtually every PC user. Features of ROSESIM for Windows are listed and discussed.

An IBM PC Based Computer Program for the Analysis of Infrared Spectra

A computerized infrared interpreter has been developed on an IBM personal computer (PC) running under the Microsoft disk operating system (DOS). Based on the original Merck Sharp & Dhome Research Laboratory Program for the Analysis of InfRared Spectra (PAIRS), this infrared interpreter, PC PAIRS+, is capable of analyzing infrared spectra measured from a wide variety of spectrophotometers. Modifications to PAIRS now allow the application of both artificial intelligence and library searching techniques in the program. A new algorithm has been devised to combine the results from the library searching and the PAIRS program to enhance the dependability of interpretational data. The increased capability of this infrared interpreter along with its applicability on a personal computer results in a powerful, general-purpose, and easy-to-use infrared interpretation system. Applications of PC PAIRS+ on petrochemical samples are described.

Constraints on Microcompute Access for Visually Impaired Persons

Microcomputers are an increasingly important part of educational and professional activities. There are six constraints on equal opportunity for visually impaired persons to access microcomputers. They are the absence of (1) a standard computer braille code, (2) a standard system for the audio encoding of braille, (3) a means for accessing unique disk-operating system (DOS) copy-protected programs, (4) reasonably priced equipment, (5) an interactive tactile graphics display, and (6) specially designed software; there may be others. These issues must be addressed if visually impaired persons are to have equal access to the benefits of microcomputers.
