I used to be work with my Lecturer of Watershed Management Laboratorium, Universitas Gadjah Mada as a volunteer researcher.
On this position, I was responsible for data field collecting, data field processing, and data recapitulation. Data field collecting placed in sub watershed's outflow, data field processing placed in Land and Water Resource Techniques (TSLA) Laboratorium, and Watershed Management Laboratorium. In Data Field processing phase, i was familiar with excel, and Sigmaplot (statistics).
