Abstract

The biogas-driven pump-based integrated farm with a total land area of 1.08 ha is located in Bakir, Bagabag, Nueva Vizcaya, Philippines. The farm owner was primarily practicing monoculture with rice as the product. Originally, the annual income of the farmer is Php 66,087.51. With the introduction of the biogas-driven pump-based integrated farming system (IFS), the income of the farm owner has increased to Php 196,940.13. The farm is now engaged in rice, vegetables, swine, and fish production. It was found out that both systems have a positive net present value; therefore, they are financially viable. However, biogas-driven pump-based IFS has a higher net present value of Php 601,461.41 compared with monoculture (Php 116,040.11). For the internal rate of return, biogas-driven pump-based IFS has a higher rate than the monoculture. Concerning the return on investment, the biogas-driven pump-based IFS has a rate of 25%, which is higher than the monoculture (13%).
