1989 Measurement of Water Flow Velocity Using Ultrasonic Waves and Sing-around method Suliyanti M. M and K. A. Zaini Thosin The Measurement of water velocity in pipe with the Ultrasonic waves and Sing-around method have been done. The measurement was based on the difference of the travel time between the ultrasonic wave propagating upstream and downstream. Sing-around method was used for measuring the travel time. In this method, one of received pulses will trigger transmitter so that periodic pulses will be found. Accurate results could be obtaind by using longer paths or accurate frequency counters. Lihat

1989 The measurements of ultrasonic waves velocity for sensor of liquid concentration K. A. Zaini Thosin and Suliyanti M. M. An ultrasonic method for detecting concentration of liquid has been cariried out. Some kind of mixture and solution are used as liquid sample. In this method the ultrasonic velocity is corelated to liquid compressibility. From the experimental work it was indicated that corelation between liquid compressibility and liquid concentration are depend on the properties of liquid. Lihat

1988 Catatan Singkat Mengenai Ikan Tembang (Sardinella fimbriata) Syahailatua, A Ikan tembang (Sardinella fimbriata) merupakan salah satu jenis ikan dari genus Sardinella (Famili: Clupeidae). Ikan-ikan famili ini termasuk ikan-ikan yang mempunyai banyak jenis yang tersebar di daerah tropik. Nilai Niaga ikan tembang relatif tidak begitu tinggi, hal ini didasarkan pada kenyataan bahwa ikan ini jarang didapatkan di pasar umum kota-kota besar di Indonesia (kecuali di kota-kota pelabuhan perikanan). Akan tetapi ikan tembang bersama dengan jenis-jenis ikan famili Clupeidae lainnya banyak dipergunakan oleh nelayan sebagai umpan hidup dalam penangkapan cakalang (Ayodhyoa 1981). Lihat

Such a slow uplift rate is supported by the observation of numerous large modernreef platforms and of very limited mid-Holocene emergence - if any - throughout the region. Subject to confirmationthrough further dating, this suggests the existence of a more rapid uplift zone in central West Timor, by contrast withthe area of Kupang… Lihat
1988 Repeated batch production of L-phenylalanine from phenylpyruvate and NH4Cl by immobilized cells of Nocardia opaca under hydrogen high pressure Tadashi Matsunaga1, Michio Higashijima1, Anny Sulaswatty1, Shigeo Nishimura1, Takanori Kitamura2, Masao Tsuji2, Toshio Kawaguchi2 Repeated batch production of L-phenylalanine from phenylpyruvate and NH4Cl by immobilized cells of Nocardia opaca under hydrogen high pressureAbstractAmong various microbial cells examined under screening conditions, Nocardia opaca showed the highest activity for production of phenylalanine from phenylpyruvate. Here NH4Cl as well as amino acids were used as an amino donor for phenylalanine production. The phenylalanine production rate increased with increasing hydrogen pressure. The specific activity of phenylalanine dehydrogenase was increased by culturing N. opaca cells in nutrient broth containing 0.3 persen phenylalanine. As a result, the phenylalanine production rate increased from 0.69 to 4.4 μmol/min g dry cells. Immobilized… Lihat
