Titanium dioxide to degrade pentachlorophenol

Pentachlorophenol is a phenolic compound that was chlorinated. Pentachlorophenol very toxic for our breath, cause dermatitis on skin and more toxic than inorganic solvent.


Pentachlorophenol waste almost dissolvable in water so degradation process is very hard. Some ways have been done to solve biological waste problem, but not efficient enough. For example, active carbon just involve pollutant absorption without decomposition process. Chemical oxidation process can’t decomposition all of organic compound be carbon dioxide and water, and have been used in high concentration waste.


Many century ago, scientist success to describe phenomenon photocatalytic in surface of metal-oxide semiconductor. Firstly, have been issued by Renz in 1921 until 1960, and not responding by scientist. Photocatalytic semiconductor popularity increase since publication Akira Fujishima in Nature magazine was issued in 1972. He was reported decomposition water be oxygen and hydrogen used single crystal TiO2 with input UV light in low energy.


First research, TiO2 have been used as photocatalytic suspension system. Nowadays, the uses TiO2 as photocatalytic is used in thin plate shape, which is immobilization TiO2 to many kinds of supported material like fiber, glass, silica, and titanium plat.

Based on the Malay trade dialect, Bahasa Indonesia is the national language of the Republic of Indonesia. It unites the over 242 million people (2005 estimate) of Indonesia, whose native tongue may be one of the over 300 distinct languages or regional dialects. Older people may speak some Dutch and English is the foreign language of choice for business, tourism and study.
While it may be technically possible for foreigners to live in Jakarta without learning/speaking Bahasa Indonesia, it is highly recommended that you obtain a working knowledge of the Indonesian national language. An inability to communicate in Bahasa Indonesia will cut you off from the mainstream of society, and dealing with those Indonesians who don't speak your foreign language will be very difficult. By not learning the language, you also deny yourself the rich cultural experience of fully communicating with those from another culture.
To get you started and introduce you to the Indonesian national language, are some basic phrases in Bahasa Indonesia.

Learning Bahasa Indonesia
The best time to start learning Bahasa Indonesia is before you even make your move to Indonesia, however it may be difficult to find language materials in your home country. Ask your sponsoring company to help you obtain tapes and books several months before you move, so that you can start becoming used to the sound of the language and start familiarizing yourself with its structure and vocabulary.
Formal Courses
Soon after your arrival in Indonesia, make it a priority to register for a Bahasa Indonesia course. There are several excellent schools and community organizations in Jakarta (and other cities) which have comprehensive, structured programs to help you begin learning Indonesian. Learning Indonesian properly from the beginning can not be stressed enough.
Another advantage of signing up for a course is that it's a great place to meet other newcomers and make friends. The people that you will be taking the course with will also be facing many of the settling in and adjustments challenges that you too face as a newcomer.
Several schools offer intensive programs, in Bali or Yogyakarta, where you can study for the full day and have some enjoyable cultural experiences as well.
Tutors
Others opt for private lessons in their home or office from private tutors. This option tends to be the most expensive, and there is little control over the quality of the curriculum and instruction. Even though the tutor may come highly recommended from other expats, that does not ensure the quality of their instruction. You may, however, find it useful to meet with a tutor for a period after you have completed several levels of a formal course. That way they can help you with any special problems or requirements you may have.
Self-Taught Bahasa Indonesia
Some expats opt to learn Bahasa Indonesia on their own. Excellent books to learn Bahasa Indonesia are available in bookstores in the major cities. Once you are in Indonesia, practice your fledgling Indonesian with your household staff, driver, vendors, people you meet in the stores, and social encounters. The diligent will quickly pick up enough Bahasa Indonesia to feel comfortable interacting with Indonesians on a daily basis.
Pen Pals and Indonesian Friends
True fluency in a language requires active use of the language. Many expats find it helpful to get a pen pal or have a "language buddy" relationship with an Indonesian where you help each other to learn a desired language by sharing your skills. This can be as simple as setting up a time to meet once or twice a week where you focus on learning language and developing a friendship over coffee or email each other any questions you have about the language.
Many Indonesians want to learn English, or French, or German ... so if you want to learn Bahasa Indonesia, offer to "trade" skills by investing time in each other's language studies. Obviously you can pay a private tutor to do the same thing, but this type of a relationship is based on mutual benefit and doesn't involve payment. One time you focus on helping the expat to learn Indonesian, and the next time you meet you focus on helping the Indonesian to learn the foreign language.
Two great places to chat with Indonesians wanting to learn English or to find an Indonesian pen pal is on the Living in Indonesia Expat Forum or the Kangguru Radio English Forum.

Goals

It would be difficult to overestimate the importance of setting goals, both personally and professionally. Goals help organizations and individuals to focus their energy and to define priorities. Secondly goals also monitor the performance of certain activities, making it possible to revise and adapt the overall strategy along the way.

On the previous post of this series (read here) we talked about the mission statement and the vision. Apart from the vision, which can be seen as the ultimate goal, any company or project will also need smaller goals to guide the day to day decisions.

Suppose you have a blog about weight-loss. Your vision is to become the most popular weight-loss blog on the entire Internet. That is the ultimate goal, but you know that you will not achieve it overnight therefore you will need medium-term and short-term goals. The medium-term goal could be to hit the mark of 5000 RSS subscriber within 2 years, while the short-term goal could be to increase the blog traffic by 20% every month.

Once you have a set of goals in place it will be much easier to coordinate your actions, for example in order to achieve the short-term goal of increasing traffic by 20% every month you could commit yourself to comment on 5 new blogs every day.

Bear in mind, however, that you should follow some guidelines when setting goals, such as:

Goals must be measurable: Your goal for this year could be “I want to improve my blog in 2007 and make it very popular”�. That is for sure a nice goal, but how are you going to know whether you accomplished it or not by the end of the year? Goals must be measurable so that you can track performance and be sure about whether you are hitting them or not. Use numbers, percentages, time frames and so on.

Goals should be realistic: If you are just starting out with a blog it would be really cool to to setup a goal like the following “Within six months I want to be receiving 10,000 unique visitors daily and generating $5,000 in Adsense revenues”. It would be cool but useless. Goals must be realistic and achievable, otherwise they will discourage rather than motivate you. Do not worry about stretching it a little bit, just make sure that you are not overshooting.

Goals must be consistent: You must not only believe that you will be able to achieve the goals, but you must also believe that they are important in your life and that they are not conflicting with other values. If you have a full-time job and a family to care it would make little sense to set a goal like “to blog at least 6 hours daily”�.

As a blogger there are several parameters that you can use to set goals, including:

* traffic
* RSS subscribers
* number of comments per post/week
* number of pages viewed by each visitor
* Alexa rank
* Technorati rank
* revenues generated
* search engine rank positions
* popularity on social bookmarking sites (i.e. Digg)
* popularity on online communities (i.e. MyBlogLog)

Finally, make sure that you record your goals, either on paper on by publishing them on your blog. The mere act of recording the goals will reinforce them on your head and motivate you to start acting immediately.

Introduction

A couple of days ago I was thinking: “There are web designers who blog and give great advice about how to design a website. There are programmers who can certainly help people to fix codes or to implement scripts. I am no professional designer or programmer, but there must be something valuable that I can share coming from my own background.”


What is my background you might ask? In 2005 I received a degree in International Economics with a minor in Business Strategy, and I have also worked for a large multinational company inside the Marketing and Business Development department.

After reflecting upon the mentioned question I realized that blogging could borrow many principles from management and business strategy. A blog, after all, can be perfectly compared to a business entity. It has managers (authors), inputs (ideas and information), outputs (posts and articles), clients (readers), competitors (bloggers or other websites on the same niche), partners (blog networks, friends), performance indicators (traffic, RSS subscribers, incoming links) and so on.

Considering all those similarities I decided to write a series of posts called”Blogging Strategy”�, with the objective of applying some important business strategy concepts to blogging. Whether your goal is to make a living from blogging or simply to share your ideas, there is no reason why you should not do it strategically!
