Pekerjaan ini bertujuan untuk megetahui pengaruh pH lingkungan terhadap kemampuan swelling dan permeasi KCl melalui membran hidrogel PVA-borat. Pada penelitian ini dilakukan (1) sintesis membran PVA-borat; (2) karakterisasi membran PVA-borat dengan spektrofotometer FTIR; (3) uji swelling ratio PVA-borat pada pH 6, 7 dan 8; (4) dan uji permeasi KCl melalui membran hidrogel PVA-borat pada pH 6, 7 dan 8. Membran hidrogel PVA-borat hasil sintesis berbentuk lembaran dengan ketebalan kondisi kering adalah 0,11 mm. Karaterisasi FTIR menunjukkan bahwa spektrum antara PVA dan membran hidrogel PVA-borat memiliki kemiripan. Tingkat keasaman lingkungan sangat nyata mempengaruhi performa swelling dan laju permease KCl melalui membrane PVA-Borat.
