Stay in Jambi - Part 1. Research

Posted on Dec 27, 2015 by



Hello, PARE friends. Today, I post my situation in Jambi, Sumatra Island.

In order to conduct my research, I left Bogor in west of Java Island. Now, I have stayed in Jambi for one month and I will stay there until the end of January. Jambi is south east province in Sumatra Island and especially the place I stay is located in coastal area. In November, there were worried by haze problem(thick smoke) due to peat fire during dry season but the rainy season has started and the haze disappeared.

My research focuses on the greenhouse gas emission from the acid sulfate soil. I take gas and soil samples in order to measure gas emission and controlling factor of the emission in the agricultural field in Jambi. Because the place I stay is coastal area, there has a lot of acid sulfate soil affected sea water. Once the soil got drained, sulfide in the soil got oxidized and produce much amount of sulfate ion (SO42-) then decrease its pH.

Even though working in the hot agricultural field exhausts me and the live in this place has difference from city area, I will work hard and contribute to this place through suggesting less environmental damage agriculture. See you again.

See you again!

Looking back this month

Posted on Nov 26, 2015 by

Hello, everyone. This is Haruka in IPB, from Hokkaido University. It’s already the end of November.. Time passes so quickly, ya..
Here, I would like to look back activities in this month.

Regarding research, I started data collection from the end of October. My research is about child health and parental practices. I interviewed mothers (sometimes fathers) in villages about their practice of feeding children, health service utilization, and so on. I also interviewed village leaders, kader (volunteer women who work in health center) and midwives.


My friends helped me a lot..





 We had some difficulty in research, for instance, making appointments. Some respondents are so busy to make appointments. Moreover, due to “jam karet (flexible time)”, we had to postpone interview many times. Through research activities, I got toughness and became more patient!
Besides research, I visit some places around Bogor.

My senior student and her family took me to park (I forgot the name..).
The park had many kinds of animal.



My friend’s supervisor in soil science invited me to Jasinga.
Very huge oil palm plantation..

 Visited Taman Mini with friends..

We enjoyed traditional housing and clothes.
And I gave a presentation to undergraduate students on Japanese parenting.
There were many students in the class.. This was the first time for me to give a lecture, but I really enjoyed it! I could communicate with many undergraduate students.


I have only one month left to stay here. I’ve not been to distant places from Bogor yet.. Before I leave, I MUST go somewhere!

Thank you for reading all! See you again!

In Order To Succeed

Posted on Dec 12, 2014 by


And after this long weeks,.,.
Here comes the..  .. .. .. .. .. ..


Can you guys see that   ?????????

Yaap,., you should know it. 
Aa aaaa. There’s nothing in there. Hahahahaa.. :v
Hmmmm,.,.,.,.,.,, let's just say it is unsmooth result.
Just like one of my old friend quote "In order to succeed you must fail, so that you know what not to do the next time".  
There he is .,., Anthony J. D'Angelo, just like what he wrote in his book "The College Blue Book". Honestly,., I never read it,. my friend told me. Lol.
Well, seems like my relationship with this big-machine not really close,., we need to  have much more date. So, let's SPEED-UP 'till the end of this year. "Vroom vroom vrooooom......"

Fly Ash

Posted on Nov 19, 2014 by

Hello everybody! I hope you still warm even in this cold weather :)


Now I will tell you about what I do in my laboratory. My laboratory is solid waste disposal engineering laboratory. This laboratory is located on Faculty of Engineering Building, Section A, 5th floor, room number A5-58. 


In this laboratory, I belong to incineration system research group. Specifically, I study about fly ash. What is fly ash? Fly ash is residue that generated from incineration (burning) process of waste along with the flue (exhaust) gases. The appearance of fly ash is just like ordinary dust. But be careful! This dust has various size from 5 to 300 µm and maybe it will cause health problem if you inhale the very small size particles. 

Fly ash (U.S. Concrete, 2011)

Considering this health risk, you will not see this dust (fly ash) is released from the chimney of the incineration plant in Japan. Fly ash cannot be released into the environment through the chimney because it will cause air pollution. So, the fly ash should be trapped in an equipment to be disposed later in the landfill. The fly ash is trapped in some kind of device called air pollution control.

My experiment is to investigate the characteristics of the fly ash. This week I investigate about physical characteristics of the fly ash. I analyze the density of the fly ash by weigh the weight of the fly ash and measure the volume of the fly ash. Moreover, I analyze about the compressibility of the fly ash.

This is all I can say to you this time. See you.
