In Indonesia, English for Specific Purpose (ESP) usually offers to students of non-English Department. It has not been any consideration that it must also be taught to students of English Department, especially for those who are in vocational higher institutions. By facilitating the learning of ESP by the institution, they will fit in any kinds of work fields. Actually, ESP must not always stand-alone to be taught. It can be integrated with the subjects provided by English Department like Public Speaking. For teaching ESP in a Public Speaking class, learning material was developed based on elements of TBL proposed by Martin Bygates which consists of need analysis, the three-phase procedure, the discovery-based element, and the project-based nature of TBLT. Gall and Borg Small Scale Model which has six phases was chosen. They were need analysis, planning objectives, developing preliminary forms of product, preliminary field testing, main product revision, and main field testing. This R&D developed a learning material named Digital Video Feature Project (DVFP) and it was implemented to 25 students who were taking Public Speaking class in English Department of Politeknik Negeri Padang. From the research, DVFP has successfully encouraged the students to be more competent in writing in the context of the chosen ESP, more skillful as a public speaker in a topic related to the chosen ESP, risen their knowledge related to the chosen ESP, and also build their social life with people related to the chosen ESP. In conclusion, DVFP does not influence the students' ESP and Public Speaking skill but also affect their mind and consideration to support any issues related to the chosen ESP.
