“…Kecepatan gelombang ultrasonik pada udara adalah 340 ms -1 . Sedangkan kecepatan gelombang ultrasonik dalam air adalah 1480 ms -1 (Gooberman 1968). Oleh karena itu, pada ubi jalar cilembu yang terserang lanas akan memiliki kecepatan gelombang ultrasonik yang lebih tinggi dibandingkan dengan yang sehat.…”

Jurnal Keteknikan Pertanian (JTEP) terakreditasi berdasarkan SK Dirjen Penguatan Riset dan Pengembangan Kementerian Ristek Dikti Nomor I/E/KPT/2015 tanggal 21 September 2015. Selain itu, JTEP juga telah terdaftar pada Crossref dan telah memiliki Digital Object Identifier (DOI) dan telah terindeks pada ISJD, IPI, Google Scholar dan DOAJ. JTEP terbit tiga kali setahun yaitu pada bulan April, Agustus dan Desember berisi 12 naskah untuk setiap monuron baik dalam edisi cetak maupun edisi online. Jurnal berkala ilmiah ini berkiprah dalam pengembangan ilmu keteknikan untuk pertanian tropika dan lingkungan hayati. Penulis makalah tidak dibatasi pada anggota PERTETA tetapi terbuka bagi masyarakat umum. Lingkup makalah, antara lain: teknik sumberdaya lahan dan air, alat dan mesin budidaya pertanian, lingkungan dan bangunan pertanian, energi alternatif dan elektrifikasi, ergonomika dan elektronika pertanian, teknik pengolahan pangan dan hasil pertanian, manajemen dan sistem informasi pertanian. Makalah dikelompokkan dalam invited paper yang menyajikan isu aktual nasional dan internasional, review perkembangan penelitian, atau penerapan ilmu dan teknologi, technical paper hasil penelitian, penerapan, atau diseminasi, serta research methodology berkaitan pengembangan modul, metode, prosedur, program aplikasi, dan lain sebagainya. Penulisan naskah harus mengikuti panduan penulisan seperti tercantum pada website dan naskah dikirim secara elektronik (online submission) melalui http:// journal.ipb.ac.id/index.php/jtep.

“…When using the analogy between electrical and mechanical transmission lines [8] it is known that the transmission matrix of two transmission lines connected in tandem is equal to the product of the individual matrices [9]. This can be generalized to obtain the expression of the transmission matrix for any number of transmission lines connected in tandem.…”

Recursive equations were developed and introduced that enable to calculate the transmitted waves through a multiplicity of layers. The calculations are carried out using z-transform technique. The layers are considered lossless and have parallel interface, which are at normal incidence to the eld. The multilayered structures are constructed of three aluminum plates connected together with epoxy as the adhesive layers. The method has been successfully used to detect small changes in the thickness of adhesive layers.

“…The transmission medium is treated as a transmission line terminated by an impedance Zt. After some algebraic manipulation, the input impedance can be calculated to be [8]: (6) where p is the density, c is the speed of sound, k is the wave number, I is the transmission line length, a is the attenuation coefficient, and Zt is the termination impedance.…”
