Rifka Aisyah at Missrifka

Hello everyone,

My name is Rifka Aisyah. I have total six years experience working as process and project engineer (2011-2017). You might think I’m no longer young. But, I feel I’m still, so I will not change the header of this blog. 😀

Currently I am looking for opportunities to work as process engineer again since I have resigned from my previous company in Bandung, West Java, Indonesia. I resigned on May 15, 2017. I keep myself busy by reading, blogging, and helping my friends.

I start writing this blog again since August 2016 after vacuum for a quite long time. The motivation behind this was actually I’m not busy enough in my work (just kidding!) and I also want to do something I like that can define myself.

As process engineer, I worked in variety of fields, starting from carboxymethyl cellulose (CMC) industry, ferronickel, turpentine, enzyme industry, and oil and gas industry. I also involved in various project, starting from:

  • Front-End Engineering Design
  • Feasibility study (pre-feasibility and feasibility study)
  • Energy audit
  • Engineering, Procurement, and Construction
  • Precommissioning activity

I realized that if I don’t write what experience I got from work, I will forget them all. So, I start writing in this blog.
