Abstract

Conventional Test System means that the test is done using paper and pencil or the current term Paper-Based Test (PBT), the constraints and shortcomings of the PBT system are no longer effective & efficient. Sorong State Vocational School 1 still uses Paper-Based Test (PBT) to carry out School Exams. Conventional systems must be replaced by computer information technology using Computer-based Tes This research resulted in an offline Computer Based Test (CBT) based test system at SMK Negeri 1 Kabupaten Sorong. The CBT system makes it easier for student and teacher examinations, the use of exam paper is reduced, examination of exam results is more efficient and effective, it can save time and money. This application system can be used for grading assignments, daily tests and midterm, final exam can even be used as a national exam tryout. The exam analysis system can make it easier for teachers or principals to accept student exam results and analyze students' abilities more quickly. Students at SMK Negeri 1 Sorong Regency will become accustomed to examinations using a computerized system or using an android mobile phone.

Abstract

Saat ini perkembangan teknologi semakin maju termasuk dibidang Sound Engineer, pada audio power amplifier secara umum masih dijumpai pengaturan potensio masih secara manual oleh sebab itu, diperlukan suatu inovasi baru dalam pengaturan audio pada power amplifier secara praktis dengan menggunakan Bluetooth berbasis Android. Pada aplikasi tone kontrol berbasis android terdapat hardware dan software yaitu modul Power Amplifier 150 watt, modul Power Supply, dan modul tone kontrol digital untuk hardware. Sedangkan software yang digunakan adalah software apk Mackie mixer connect. Pengaturan tone kontrol memiliki 2 cara bisa digunakan secara analog (pengaturan audio secara manual) atau menggunakan apk tone digital Android. tone kontrol berbasis android memiliki 6 channel didalam penambahan dan pengurangan audio (Gain, High, Middle, Low, Volume, dan Master volume). Nilai efisiensi dari daya input dan daya output saat volume tinggi 86,37%. Tone kontrol digital dapat tersambung melalui Bluetooth sampai jarak maksimal kurang lebih 10 meter
