LAPORAN PENELITIAN Pola Kecenderungan Penempatan Kunci ...

Populasi yang diambil untuk penelitian ini adalah soal-soal ujian matakuliahmatakuliah pada program studi Statistika Terapan dan Matematika FMIPA yang mempunyai tipe D - melengkapi berganda. Dugaan semula bahwa ada kecenderungan penulis soal meletakkan kunci jawaban soal di tengah-tcngah (menurut Dorothy C. Adkins), setelah melalui penelitian ini kecenderungan tersebut ternyata bahxva penulis lebih tertarik menempatkan kunci jawaban pada option 1, 2 dan 3 benar atau kunci jawaban D. Soal tes/ujian sebagai salah satu alat pengukuran pendidikan disusun untuk tujuan mengukur sampai seberapa jauh kedua fungsi pendidikan terscbut berhasil dicapai. Bcntuk soal ujian yang dipakai oleh Universitas Terbuka pada umumnya pilihan berganda, hanya sebagian saja dalam bentuk essay (uraian). Dalam hal ini FMIPA Universitas Terbuka sampai dengan masa ujian 90.1 telah mengembangkan sebanyak 61 matakuliah, sebagian besar soal ujian dalam bentuk pilihan berganda kecuali 12 matakuliah yang bentuk soal ujiannya adalah essay (uraian). Universitas Terbuka, dalam penyelenggaraan ujiannya, mcnctapkan 5 (lima) macarn tipe soal ujian yaitu:...

KREATIVITAS: EVALUASI BUKU PELAJARAN ... - Digilib UNIMED

Buku pelajaran sebagai sasaran evaluasi karena buku pelajaran memiliki potensi menjadi agen perubahan yang efektif (Hutchinson and Torres, 1994:322) dan buku pelajaran digunakan di seluruh sekolahsekolah yang ada di pelosok tanah air. Umumnya, pada saat guru mengajar, terutama untuk tingkat sekolah dasar, guru cenderung hanya berpedoman ada buku pelajaran, baik urutannya maupun materinya bukan pada kurikulum. Berdasarkan hal ini diduga ada sesuatu yang tidak diajarkan oleh buku pelajaran sehingga daya kreatif siswa tidak berkembang dengan baik. Untuk itu perlu dilakukan evaluasi buku pelajaran. Kreativitas merupakan sintesa dari keseluruhan fungsi yang tediri dari: (1) pemikiran rasional, (2) pengembangan tingkat tinggi dari emosional/ perasaan, (3) pengembangan tingkat tinggi dari mental dan fisikal, dan (4) kesadaran tingkat tinggi, hasil imajinasi, fantasi, dan pemecahan permasalahan yang cepat. Daya kreatif siswa dapat diteliti pada saat proses belajarmengajar berlangsung tetapi dapat juga diteliti dengan cara mengevaluasi buku pelajaran yang digunakan dalam proses belajarmengajar di kelas. Dalam hal ini, tulisan ini hanya dilakukan pada buku pelajaran saja yaitu dari latihan-latihan dan tugas-tugas yang tertera di dalam buku pelajaran.

PSPICE tutorial: a simple DC circuit - Tuttle

PSPICE tutorial: a simple DC circuit We will learn some of the basic maneuvers of using the Cadence schematic capture program and PSPice engine through a simple example -- a diode rectifier circuit. The tutorial starts under the assumption that the demo version of PSPICE is installed on your computer. The latest version available for download is 16.6. If you want a copy to install on your own Windows machine, go here http://www.cadence.com/products/orcad/pages/downloads.aspx and follow the instructions to download the OrCAD 16.6 demo software. You will probably want the option for Capture & PSpice only. Getting started Start the Orcad schematic capture program (Start -> Programs -> OrCad 15.7 Demo -> Capture CIS Demo). Start a new project by selecting (File -> New -> Project...) from the menu in the OrCAD Capture window. In the dialog that opens, provide a project name, a file path to where you want your project stored, and select the item "Analog or Mixed A/D". Click OK.

QRD1113 / QRD1114 Reflective Object Sensor - Fairchild ...

Description The QRD1113 and QRD1114 reflective sensors consist of an infrared emitting diode and an NPN silicon phototransistor mounted side by side in a black plastic housing. The on-axis radiation of the emitter and the on-axis response of the detector are both perpendicular to the face of the QRD1113 and QRD1114. The phototransistor responds to radiation emitted from the diode only when a reflective object or surface is in the field of view of the detector.

sc1088 - The Way Of Engineer
by dietdude 0 Comments favorite 8 Viewed Download 0 Times

FM RECEIVER CIRCUIT FOR BATTERY SUPPLY DESCRIPTION The SC1088 is a bipolar integrated circuit for use in mono portable and pocket radios. It is used when a minimum of perpheral components (of small dimensions and low costs) is important. The circuit contains a frequency-locked-loop(FLL) system with an intermediate frequency(IF) of about 70kHz. Selectivity is achieved by active RC-filters. De-tuning related to the IF and too weak input signal is suppressed by the mute circuit. FEATURES * Equipped with all stages of a mono receiver from antenna to audio output. * Mute Circuit * Search tuning with a single varicap diode * Mechanical tuning with integrating AFC * AM application supported * Power supply polarity protection * Power supply voltage down to 1.8V SOP-16 APPLICATION 1. Mechanical tuning: This is possible with or without integrated AFC circuit 2. Electrical tuning: This is realized by one directional(band-up) search tuning facility, including RESET to the lower-band limit.

Nije zapadni sistem superioran, to ima veze sa privilegijom koju je zapad sebi prisvojio, a to je stampanje novca u nedogled, ili 'out of thin air'

Nije zapadni sistem superioran, to ima veze sa privilegijom koju je zapad sebi prisvojio, a to je stampanje novca u nedogled, bez pokrica, ili kako se to popularno kaze "out of thin air". Svako zna platiti naucnika enormno, ali je drugacije kada je za to potrebno stvoriti vrednost, recimo u paradajzu, kozama ili gasu. Ruska nauka je pratila zapadnu i bez novaca. Izumitelj LED diode je umro u opsadi tadasnjeg Lenjingrada. ******** НОВАЦ БЕЗ ПОКРИЋА

Testing Electrical Systems with a Digital Multimeter - Fluke

Testing Electrical Systems with a Digital Multimeter Perhaps the most important tool you'll use in troubleshooting auto electrical systems is the multimeter. Basic multimeters measures voltage, current and resistance, while more elaborate multimeters, such as the Fluke 78, or Fluke 88 have featues that can check things such as frequency, duty cycle, dwell, make diode tests, and even measure temperature, pressure and vacuum. Starter Current S tarting system troubles are often confused with charging system problems. Many a dead battery has been replaced when the real cause was a faulty charging system. Be sure that the charging system is functioning properly before you replace the battery. Make sure the battery is charged and passes a load test, then look for resistance in the starter circuit if the engine still cranks slowly. Investigate excessive current draw; check for worn-through insulation, a seized or tight engine, a faulty starter, etc. If the starter turns the engine slowly, the current draw is not high, and the battery is in good condition, check the resistance in the starter circuit. Fig 6 - Measuring Starter Current Draw Determine how much current the starter is drawing by using Fluke's 80i-401, 80i-1010, or 90i-610s Inductive Current Clamp on the starter cable. This accessory will allow the multimeter to measure starter current up to 1000 amps. Check manufacturer's specs for exact figures.
