This final project report is written based on the job training done at PT Angkasa Pura I Adisutjipto International Airport Yogyakarta for a month at the General Affair and Communication Section. I did some jobs with my supervisor of Public Relations Officer in PT Angkasa Pura I Adisutjipto International Airport Yogyakarta. I helped my supervisor accomplish his jobs such as, making clipping, distributing news cuttings, documentation events, editing and writing news, making press releases, and handling the website of PT Angkasa Pura I Adisutjipto International Airport Yogyakarta. The objectives of this final project report are to analyze the effectiveness of website as communication channel in PT Angkasa Pura I Adisutjipto International Airport Yogyakarta and propose improvement of website in PT Angkasa Pura I Adisutjipto International Airport Yogyakarta. So, this final project report can help them improve the existing communication and keep good reputation. I propose improvement to make official website more effective.
