Penelitian ini bertujuan untuk mengetahui kandungan fitokimia serta aktivitas antibakteri sepuluh jenis tanaman  terhadap bakteri Vibrio alginolyticus dan Aeromonas hydropilla. Dipilih  10 jenis tanaman yang sering digunakan sebagai obat dan banyak ditemukan di kota Kupang seperti tanaman Phyllanthus acidus, Euphorbia hirta, Persea gratissima, Euphorbia thymifolia,  Morus australis, Justica gendarussa, Paederia scandeus, Annona squamosa,  Sesbania sesban,  dan Jatropha gossypifolia. Bagian tanaman yang digunakan adalah daun, kecuali E. hirta dan E. thymifolia digunakan seluruh bagian tanaman.  Kesepuluh jenis tanaman tersebut dibuat bubuk,  kemudian diekstraksi dengan cara dimaserasi secara bertingkat mulai dari pelarut n-heksan, etil asetat dan metanol, selain itu, juga digunakan ekstrak air  tanaman tersebut. Semua jenis ekstrak tanaman diuji antibakteri dengan menggunakan metode cakram. Jenis ekstrak yang aktif selanjutnya diuji antibakteri pada konsentrasi 10%, 1% dan 0,1%.  Hasil penelitian menunjukkan bahwa jenis  tanaman  yang berpotensi sebagai antibakteri pada budidaya ikan laut adalah  esktrak air dan metanol E. hirta dan E. thymifolia. Sedangkan jenis tanaman yang berpotensi sebagai antibakteri pada budidaya ikan air tawar adalah ekstrak air  E. hirta dan E. thymifolia daun J. gendarussa.

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
