EDITOR'S NOTES

ASEAN Journal of Chemical Engineering volume 5 number 1, June 2005, features ten (10) papers presented during RSCE 2002 and RSCE 2003. From these papers, find out from R. Handogo, Avon T. H., and J. Lelono (Malaysia) when the steady-state RGA method should be used and when to resort to dynamic interaction measurements, such as ADGA and INA, to arrive at the most accurate controller pairing when measuring dynamic interaction measurements in multiloop control systems; "- Pavarajarn D. Wongwattanasate, P.Praserthdam S. Assabumrungrat, (Thailand), and S. Goto (Japan) the prospects of producing ETBE through direct synthesis from EtOH and TBA using highly selective 13-zeolite catalyst in a semibatch reactor and how heat duty, molar ratio of H20: EtOH, and reflux ratio affect production;.

R. G. R. Tan and D. E. Cruz (Philippines) how fuzzy nonlinear programming for the synthesis of robust water reuse networks help industries balance the need to achieve water reduction targets with the need to meet process limiting concentrations as uncertainties in the true mass loads arise during operation;

T. Watanabe (Japan) how the application of halogenated hydrocarbon decomposition can help in the design and construction of a portable plasma-generation system that does not require gas supply units;

G. Najafpour (Iran), H. Younesi, and K.S. Ku Ismail (Malaysia) the optimum substrate concentration for the maximum growth of R. rubrum for use as biocatalyst in large-scale hydrogen production from synthesis gas with high CO-uptake in the light of developing renewable resources and environmental sustainability;

A. Mindaryani, B. tv. Tyoso, tv. Sediawan, and Supranto (Indonesia) the particle scale kinetic parameters of strongly adsorbed VOCs in ;:\ctivated carbon using differential permeation technique; p. y: Ooi, T. T. Teng, A. K. M. Omar, and N. A. R. Nik Norulaini (Malaysia) the optimal conditions as well as the best dosage and combination of MgCI2, alum, and MgCl2 and alum as aqueous coagulant to achieve the highest percentage removal of color and suspended solids, specifically in Levafix Brill Blue EBRA, in treating textile wastewater;

P. Pavasant, P. Wongsuchoto, and "- Suksoir (Thailand) how they came up with a mathematical model that could predict oxygen mass transfer behavior in an internal loop ALC with reasonable accuracy with no need for parameter fittings;

L. Andalaluna and M. Sugioka (Indonesia) what are the enhancement effects of hydrogen sulfide over metal ion-exchange mesoporous silicate FSM-16 in acid-catalyzed reactions; and M. M. Mustafa, S. A. S. Rozaimah, and A. R. Rakmi (Malaysia) how the proposed modification to DS's combination rule in combining sequences of evidence from the same source, while also considering different times, successfully overcomes deficiencies in the theory meant for application in the removal of toxic chromium ions in wastewater.
