VISUAL IMPACT ASSESSMENT assalamu’alaikum wr. wb PERENCANAAN TAPAK VISUAL IMPACT ASSESSMENT Johannes Parlindungan Siregar PERENCANAAN WILAYAH DAN KOTA UNIVERSITAS BRAWIJAYA

PENDAHULUAN KUALITAS LINGKUNGAN MERUPAKAN OUTPUT PALING PENTING DALAM PERENCANAAN SALAH SATU KOMPONEN UTAMANYA ADALAH PENAMPILAN

TUJUAN ANALISIS 1 MENGUKUR PERANAN VISUAL SUATU BENTANG ALAM TERHADAP TAPAK KAJIAN 2 MENEMUKAN POTENSI DAN PERMASALAHAN VISUAL TAPAK 3 MENENTUKAN TINDAKAN YANG SESUAI DALAM MENGEMBAGKAN POTENSI VISUAL TAPAK SESUAI KONSEP PERENCANAAN
