Introduction to the UGAS students

Specialty: Bioproduction science, Division: Biocontrol and bioenvironmental Sciences  
Mr. Ahdiar Fikri Maulana


Biocontrol and bioenvironmental Sciences
Mr.Ahdiar Fikri Maulana

The reason why you enrolled at UGAS:

I am interested in studying symbiotic fungi in the forest since my undergraduate study. One of research topics of my supervisor in UGAS is related to symbiotic fungi in Indonesia. I enrolled at UGAS because I would like to study about symbiotic fungi in Indonesian forest.



Outline of your doctoral research:

I am studying about arbuscular mycorrhizal, ectomycorrhizal and endophytic fungi from forest of Indonesia. Objective of my research is to isolate and characterize those three groups of fungi, especially about their relationship with host plant.

Goal of your research / Vision of the future

The target of my research is to isolate mutualistic fungi for Indonesian tree species and understand the mechanism how the mutualism can be occurred. In the future, I wish to use these fungi to support reforestation effort in Indonesia.

The reason why you enrolled at UGAS:

In 2011, I decide that I needed to study at abroad because it was necessary to my future career. I needed to select the nearest developed country to Thailand because I have family to take care of and may need to often return to visit. The answer is Japan. Once I had decided the country,  I had to select a university that had an expert professor in ruminant nutrition.
The Tohoku area is a key area for food production in Japan and valuable for national agriculture. Therefore, the universities in this area were my selection, and  I had a an offer of support from Prof. SANO Hiroaki to study in the Laboratory of ruminant nutrition and physiology, Department of Animal Science, Faculty of Agriculture, Iwate University, by enrolled at UGAS.


Outline of your doctoral research:

My doctoral research title is “Effects of urea supplementation under negative energy balance on ruminal characteristics, glucose and urea metabolism in sheep”. This research investigates the effect of urea supplementation used during the negative energy balance (NEB) period on rumen fermentation, glucose and urea metabolism. Urea is non-protein nitrogen source usually used in ruminant feed. However, because of its high ammonia level, use of urea supplementation, and/or NEB has a negative effect on animal health and production. Until now, little information is available focusing on metabolism kinetics from In vivo studies. Determination of the glucose and urea kinetics using isotope dilution methods gives us a dynamic understanding of glucose and urea metabolism.

Goal of your research / Vision of the future

The goal of my research is to determine the safe urea supplementation level that can be used in ruminants during NEB. In the future I would like to study liver metabolism, because the liver is the main energy producing organ for glucose and urea in ruminants. More understanding in liver metabolisms will provide more information. Finally, we can apply this knowledge to improve feeding and management at the farm level that can be minimise incidence rates of metabolic diseases due to enhancement ofthe liver condition.
