TL;DR: In this paper, the feasibility of interactive multimedia according by expert team and its uses as learning media at SMP N 3 Ungaran was evaluated on a limited scale trial, and the results showed that multimedia is very good to use.
Abstract: Tujuan penelitian adalah untuk mengetahui kelayakan multimedia interaktif menurut tim ahli dan penggunaannya sebagai media pembelajaran di SMP N 3 Ungaran. Hasil penelitian menunjukkan, pada tahap validasi desain oleh tim ahli diperoleh persentase kelayakan dari aspek media, materi, dan keterpaduan, masing-masing sebesar 92%; 92,40%; dan 100% dengan kriteria sangat layak. Setelah direvisi, diperoleh peningkatan persentase untuk masing-masing aspek sebesar 94,44%; 93,93%; dan 100% dengan kriteria sangat layak dan multimedia interaktif siap diujicobakan pada skala terbatas. Pada uji coba skala terbatas, diperoleh hasil persentase keterbacaan oleh siswa sebesar 85,39% sedangkan oleh guru 98,61% dengan kriteria yang sama yaitu sangat baik dan tidak terdapat saran perbaikan sehingga multimedia dapat digunakan untuk uji coba skala luas. Pada uji coba skala luas, diperoleh hasil bahwa multimedia sangat baik untuk digunakan. Hal ini ditunjukkan dengan persentase penggunaan multimedia oleh siswa sebesar 89,5% dan oleh guru sebesar 95,2%. Hasil tersebut diperkuat oleh pencapaian hasil belajar siswa yang meningkat. Hal ini ditunjukkan dengan peningkatan persentase ketuntasan klasikal dari hasil pre-test 80,65% meningkat menjadi 100% pada post-test . Berdasarkan hasil tersebut, dapat disimpulkan bahwa multimedia ini sangat layak dan sangat baik untuk digunakan sebagai media pembelajaran IPA Terpadu pada tema sistem gerak pada manusia. The purpose of research is to know the feasibility of interactive multimedia according by expert team and its uses as learning media at SMP N 3 Ungaran. Research results show that in phase of the design validation by expert teams obtained the percentage of media feasibility from aspects of media, materials, and integration, respectively 92%, 92.40% and 100% with very feasible criteria. After revised, obtained the improvement of the percentage for each aspect respectively is 94.44%, 93.93% and 100% with very feasible criteria and the developed multimedia is ready been tested on a limited scale trials. On limited scale trial, obtained the results of legibility percentage by students is 85.39% while 98.61% by teacher with the same criteria that is very good and did not obtain suggestions for revision so that multimedia can be used for large scale trials. In large-scale trials, the results showed that multimedia is very good to use. This is indicated by the percentage of multimedia using by students is 89.5% and 95.2% by teachers.

TL;DR: Gelombang ultrasonik merupakan gelombang akustik ying memiliki frekuensi mulai 20 kHz hingga sekitar 20 MHz as mentioned in this paper.
Abstract: Gelombang ultrasonik merupakan gelombang akustik yang memiliki frekuensi mulai 20 kHz hingga sekitar 20 MHz. Frekuensi kerja yang digunakan dalam gelombang ultrasonik bervariasi tergantung pada medium yang dilalui, mulai dari kerapatan rendah pada fasa gas, cair hingga padat. Jika gelombang ultrasonik berjalan melaui sebuah medium, Secara matematis besarnya jarak dapat dihitung. Sensor Ultrasonic PING merupakan modul sensor Ultrasonik ini dapat mengukur jarak antara 3 cm sampai 300 cm. Keluaran dari modul sensor ultrasonik Ping ini berupa pulsa yang lebarnya merepresentasikan jarak. Lebar pulsanya yang dihasilkan modul sensor ultrasonik ini bervariasi dari 115 uS sampai 18,5 mS. Dalam pengujian ini, dibuat sebuah alat yaitu untuk mengukur level ketinggian zat cair menggunakan gelombang ultrasonik berbasis mikrokontroler AT Mega 16. Sensor yang digunakan adalah sensor PING . Pengujian menggunakan bejana bulat berdiameter 60 cm yang dapat menampung air/cairan
