Pada era teknologi seperti saat sekarang ini, komputer memainkan peran yang semakin meningkat dalam berbagai bidang sisi kehidupan manusia. Penerapan teknologi informasi sudah sangat banyak digunakan dalam berbagai bidang, salah satunya dalam bidang pendidikan. Teknologi informasi sudah berkembang secara cepat dan bidang pendidikan turut mengalami peningkatan dalam hal kualitas, kecepatan, kepraktisan dan juga kemudahan. Di beberapa perguruan tinggi masih terdapat ujian semester yaitu ujian tengah semester dan ujian akhir semester dan penerapan ujian semester masih dilakukan secara konvensional yaitu dengan menggunakan kertas dan alat tulis sebagai penunjang ujian semester. Hal tersebut menyebabkan memakan banyak biaya dan waktu. Biaya dalam hal ini pihak kampus banyak mengeluarkan dana untuk membuat soal ujian dan memfotocopy soal ujian tersebut serta harus mengeluarkan dana tambahan untuk lembar jawaban. Dan waktu dalam hal ini adalah lamanya tahap proses mengkoreksi jawaban untuk menghasilkan sebuah nilai dari setiap mahasiswa/mahasiswi. Dengan dibuatnya Aplikasi Ujian ini diharapkan dapat mempermudah dosen dalam membuat soal, mengoreksi jawaban, mempermudah mahasiswa dalam melaksanakan ujian secara online. Kata Kunci : Teknologi informasi, Ujian, Aplikasi.
The occurrence of problems regarding operating procedures that are not suitable for heavy equipment in the field is one of the causes of component life which is not maximally achieved. Therefore it is necessary to have an innovation to make it easier to monitor and operate heavy equipment, especially when there is a shift in work shift for heavy equipment operators. Operator experience in several mining activities, many operators shut down the engine suddenly so that the impact on the engine can cause over heating which results in excessive wear and will have an impact on engine performance. And therefore the purpose of design a microcontroller-based cooling down safety device is a tool that functions to turn off the engine when the engine is low idle with time settings according to the standard operating procedure of each machine. For machines that have been operated under load, the engine must be low idle / cooling down for a while, so that the heat on the engine surface is cool enough, so that hot components can be properly lubricated. By design a cooling down engine safety device, it is hoped that it can assist in the monitoring and operation of heavy equipment. From the results of field testing, the relay that controls the unit's electricity functions properly and the cooling down safety device has a precise timing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
