Sejauh ini, metode optik untuk pengukuran konsentrasi phytoplankton masih jarang dimanfaatkan di Indonesia. Dalam penelitian ini dilakukan perancangan, perakitan dua sensor optik untuk mengukur konsentrasi phytoplankton, khususnya chlorella spp. galur UI Depok yang dikulturkan dalam medium ekstrak tauge.
Penelitian ini terdiri atas dua bagian utama, yaitu pengujian karakteristik optik yang mencakup...

The role of shock wave in the generation of laser induced secondary plasma was first suggested by Kagawa et al. from an experimental result employing N2 laser on metal targets at reduced surrounding air pressure. This so-called shock wave induced plasma model has since been reexamined and confirmed in a...

In spite of abundant experimental evidences supporting the viability of the laser induced shock wave plasma model for the explanation of the important features ofthe plasma and the associated spectroscopic characteristics, a controversy on the atomic excitation mechanism in the plasma has remained to be completely resolved. In this study...

ABSTRACT
An comprehensiove study has been carried out for the study and extension of lases induce shock wave plasma spectroscopy (LISPS) application to non metalic soft and hard samples. For this purpose, a series of experiments were conducted to investigate the dynamical process taking place in the laser plasma generated by...

ABSTRACT
A comprehensive study has been made on the dynamical process taking place in the laser-plasma generation i.nduced by a TEA CO2 laser bombardment on metal target and non-metal target Eom low to high pressures surrounding gas. ln the case of metal target, pure zinc plate was used as a target...
