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.

Engineer Term: Civil and Environmental Engineer
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.
Global Warming: Conclude yourself
It’s really challenging or either quite confusing for those whose background is not related to global warming or air pollution. I am Environmental Engineer, but I am really not major on this. This begins when I watched A Unconvenient Truth, presented by Al-Gore, when at the movie he talked about global warming, and the problem is this movie was shown on the class which has nothing to do with global warming, Environmental Emerging Contaminants. Amazingly, I keep thinking about the impact that may occur because of global warming, from what he said.
Obviously, what the movie was telling that, we have been emitting such huge amount of CO2 annually, and that cause the increase of solar radiation trapped by this gas, thus results in an increased temperature, and rise the temperature. The effect, ice melting, just like what had happened in Canadian Arctic recently as a result of global warming.
Global warming wins
Nope, not literally “global warming” wins but the movie that is talking about global warming. Yup, Al Gore, main actor on his documentary movie “An Inconvenient Truth” has won Oscar for best documentary movie.
Complete the first task
So, basically what I am going to do is to complete first target within this month. I hope I can accomplish it ontime. It has already been posted before about the performance in terms of flux, rejection of several membrane pore size, 50 kD and 15 kD. Now, I will try to use 1 kD and to repeat 15 kD which the last data seems invalid.
Environmental Engineering Roots
Environmental engineering is a relatively new profession with a long and honorable history. The title of “Environmental engineer” interestingly was not used until 1960s in US, when academic programs in engineering and public health schools broadened their scope and wanted to have special and accurate title to describe their material and courses. Thus, the differentiation between environmental engineer and public health or other engineering part hopefully become more clear.
Outline of Introduction of Environmental Engineering Course
This is the outline of the class of Introduction of Environmental Engineering. Oke, let’s get straight to the point. Several topics that I am going to explain here are as follows:
1. Environmental Engineering Roots and History
2. Environmental Impact Assessment
3. Risk Analysis
4. Water Pollution and Water Quality
5. Water Supply and Water Treatment
6. Wastewater Treatment and Collection
7. Sludge Treatment and Disposal
8. Nonpoint source water pollution
9. Hazardous Waste and 3R (reuse, recycling and recovery)
10. Air Pollution and Air Quality.
