Water scarcity is the largest limitation of agricultural development in a semi-arid zone. Water harvesting would be one of viable practices the severe restriction of funds to develop conventional water resources. I am widely interested in developing economical water harvesting system in automatic irrigation. I have majored in pure physic since I was in undergraduate student

During my master’s I have been studying water engineering sciences. In addition, five years ago as a research engineer corporate in the Ministry of Research Scientific and High School, I implemented Water harvesting irrigation using a reservoir and co-working with smallholders on rice and cowpea cultivation under soil fertility management through participative research.

My research Doctoral course focuses, in developing economical design of a water harvesting system using a tank and plastic sheet. To determine the optimal economical design of this water harvesting design, a field experiment is being carried out on a sandy soil in the Arid Land Research Center, Tottori University, Japan, in order to find the optimal tank capacity under garlic growth which gives the highest net income. A numerical model in predicting water content and yield was conducted to compare the accuracy of the water harvesting system that give the highest net income, considering tank capacity storage and tank price. In addition, I’m interested in how to secure crop production under salinity stress.

In future, I would like to work with international researchers, irrigation equipment’s company for co-creation and educational related in irrigation and drainage.
