I just read my local newspaper and there were two news catching my eyes. The first one was talking about water scarce in Tiongkok, or some of you may say China. While we sometimes use water excessively and exploit water too much, there are our brothers out there who need water badly. Water scarce as reported happens in Hainan Province, South of Tiongkok due to hight dryness. More than 120 thousands people experienced clean water crisis and paddy field dry due to lack of water.

Water supply in Surabaya
Drinking water scarce, it was the headline of popular newspaper in my city. Citizens were yelling to ask local authority to safe drinking water. The problem is, water is renewable resource, which will never be empty, always be there for water supply. So, why do these people feel that they do not get appropriate drinking that they deserve to get?
TiO2-UV performance
First stage of experiment has been accomplished. The result was not satisfying. I used 50, 15 and 1 kD. In terms of flux and accumulated flux, TiO2-UV displayed lower result compare to just naked membrane. Although for 50 kD and 15 kD initial flux were higher than naked membrane, but after around 30-100 minutes, they showed severe decline for flux. This also applied for 1 kD TiO2-UV membrane. I do not think that permeability plays a big role on this, since the permeability of all membranes were similar, there were not significant difference. This also proves that TiO2 does not affect the structure of the membrane.
Abstract for Scientific Paper
Yesterday I was requested to join Internation Symposium held in Taiwan. One of the requirement to join is to submit abstract before due date which is next week. While I am writing my own abstract, I think it is good idea to put something here about how to write abstract.
Wastewater Reuse
Today, I have Environmental Emerging Contaminants class. Its relatively new subject in Taiwan, especially in Indonesia. However, I am not going to talk about these particular contaminants, but I promise to myself, as soon as I have time, I will make some introduction of emerging contaminants.

We know that most part especially throughout europe and US, environmental engineering is usually part of civil engineering. This is because inside civil engineering, contains information, field of study which are now studied under environmental engineering. Upon graduation, we will be designated a “engineer” title. The term of civil engineer title itself came from a long history.
