about

TL;DR: Anti-Microsoft word, anti-Microsoft excel, anti-Microsoft PowerPoint, anti-What's App. If you force me to use them, I will escape, for sure!

I was born in Pasuruan, a small city in the province of East Java, Indonesia. Before one year old, my family had moved to the western part of East Java, Magetan city, where I spent my elementary school at SDN Gulun III and junior high school at SMP 1 Maospati.

Moving to senior high school, I attended a school in Jombang city, still in East Java, Indonesia. I studied natural science and Islam in an Islamic boarding school called SMA Darul Ulum 2 - BPPT, stayed in Pondok Tinggi for two years, and then I moved to Asrama nDalem Selatan (Ardales) in the third year, still in Darul Ulum. Three years I spent there, then I got an offer to continue my studies at ITS, Institut Teknologi Sepuluh Nopember, Surabaya city, the hometown of my mom.

After finishing a bachelor's degree in ITS, I continued it to a master's degree in the same laboratory, the same university. At the end of my master's degree, I got a scholarship to do my master's research at Kumamoto University, Japan, for one year, but I did it for six months. After finishing my master's research at Kumamoto University, I got a job in a metal parts company in Kameyama-shi, Japan, a city in Mie prefecture. It is a neighbor of Suzuka, home of Honda, and about 40 minutes by train from Nagoya, Aichi-ken, home of Toyota. I lived there for two years and three months (2012-04 ~ 2014-06).

In 2014 I came back to be a member of VibrasticLab, ITS Surabaya, Indonesia. From 2017 to 2021, I am with Akagi-lab to do my Ph.D. at JAIST, Japan. Now (2021 ~ ), I am with Artificial Intelligence Research Center, AIST Tsukuba, Japan. According to the result below, I am a logistician  (2017, 2021/4) architect  (2019/11). According to this, I am a kinesthetic learner.

2017 & 2021 results: Logician
2019 result: Architect

My job now is lecturer and researcher. I am interested in obtaining as much information as from speech/audio data: acoustic information processing. My undergraduate/bachelor's research theme is about recognizing machine fault conditions from its sound/noise. My master's studies are intended to understand how human auditory processing works to separate and locate sound sources and implement them into a computational method. This represents what is called the cocktail party problem. My Ph.D. has been focused on the implementation of speech processing for linguistic, paralinguistic, and nonlinguistic information recognition, particularly speech emotion recognition. You can check my publication page for my research progress. Particularly, you can hire me for such projects related to my skills (contact my email below).

In my spare time, I write for fun, hack my own laptop, and do traveling/hiking/trekking.

about this blog

I made this blog incidentally while waiting for the airplane in Sultan Mahmud Badaruddin II airport, Palembang, Indonesia, in 2007. My friend from the Informatics department shows me how interesting the blog is. You can read my first post written on a public internet airport here. As an achievement, this blog was awarded as favorite #1 in the Muslim blog contest for the article "anti korupsi: belajar kejujuran dari pengemudi taksi (Indonesian language)".

Why black/dark?
As you come to this site, the dominant color is black and dark color. Why do I use black and dark colors?  Because black will save energy on your PC (and of course my PC too). Let's save energy; let's use black. Save energy, and be safe for our eyes.

Learn. Share. Inspire. Contribute.
I learn a lot from this life, including the net. Through this blog, I share what I have learned. Last but not least, I hope this blog is my contribution to inspiring others. However small it is, it should contribute to others. Therefore by writing in this blog, I want to inspire and contribute to my community.

/home/bagustris
I named this blog bagustris@/home with the tagline "move dynamically". Why? Because "home" is my default location in Unix/Linux-based OS and I moved dynamically there and here, in other places. The "/" is a root, combined with "home" creates "/home" followed by the username. You can check it by a command in terminal "pwd". So, I named it bagustris @ "/home". Previously I named this blog "QuranicScience" because most posts are about Islam and Science. Currently, I post about all fields related to my life. It is dynamic depending on my mood, my job, and my interest. The main topics are including but are not limited to QuranicScience, blogging/writing, Information Technology, Traveling, Learn/Share, and Inspiration/Contribution.

Blogging Style

I named my blogging style 3p+1i: three points + one image. I explained it here. Simply speaking my post will be arranged in three parts: introduction, main content, and conclusion along with one supporting image minimally. It is simple writing. However, sometimes it is hard to make details short; elsewhere, some text doesn't need supporting images.

Writing Frequency and Subscription

I planned to write weekly, about 4 posts for each month or 48 posts for a year (writing is hard). The new article usually (but not always) appears on Sunday morning. Currently, I didn't use any tool to let you know when a new article is posted. The best thing you can do to follow my publication is by following me on Twitter: https:/twitter.com/btatmaja. That Twitter account will automatically post my new article from this blog.

The struggle is not over yet,
Never sing the victory till the end of the battle!
And,
All roads lead to Rome.

DISCLAIMER

I started to write in this blog in the 2nd grade of my bachelor's degree. Some of my writing may be (scientifically) wrong and/or unproven. I still keep those writing for learning purposes. Moreover, I didn't include references in my early writings, which is bad behavior; some of the writings were copied from somewhere, and now the original source has gone which makes it difficult to include the original source later.
