Abstract

One of the simplest approaches to improve membrane performance is to increase the hydrophilicity of the membrane. This article describes the manufacture of activated polyvinylidene fluoride (PVDF) based membranes using PVP and chitosan as organic additives, with the specific aim of increasing the hydrophilicity of the membranes. Variations of dope solution were made by adding 1% by weight of PVP and 1, 2, and 3% by weight of chitosan into three different PVDF polymer solutions. The effect of additives on the membrane was obtained by evaluating chemical functional groups by ATR-FTIR, morphological changes by SEM, and filtration performance. SEM images show that the presence of additives changes the morphological structure of the membrane. This change also had a significant impact on the membrane performance, as evidenced by the increased permeability of the pure water solution and the removal of dissolved humic acid. Overall, modified PVDF membranes with 1% by weight of PVP and 1, 2, and 3% by weight of chitosan resulted in much better permeability than unmodified PVDF membranes due to their excellent hydrophilicity.

Abstract

Tujuan penelitian adalah mengkaji mutu air sungai dan mengembangkan berbagai upaya penanggulangan cemaran secara berkelanjutan yang dapat diterapkan dalam kehidupan masyarakat. Kualitas air Sungai Krueng Daroy di Kota Banda Aceh dinilai dengan membandingkannya dengan Peraturan Pemerintah Republik Indonesia No. 22 Tahun 2021. Dalam penelitian ini digunakan matriks SWOT sebagai teknik. Kualitas air sungai mengalami penurunan baik di hulu maupun di hilir sehingga meningkatkan indeks pencemaran. Berdasarkan analisis SWOT, kebijakan pengelolaan Sungai Krueng Daroy kini berada di kuadran III, dengan karakteristik S<W dan O>T, artinya strategi yang ada harus diganti dengan strategi yang baru. Strategi ini dapat diterjemahkan dengan mengoptimalkan potensi yang ada guna meminimalkan ancaman yang ada, yaitu dengan memanfaatkan peluang yang muncul dari unsur-unsur peran pemerintah dan memprioritaskan kebijakan dengan (1) strategi pemanfaatan sungai yang berkelanjutan; (2) pengetahuan dan pencegahan pencemaran sampah dan limbah di sepanjang sungai kepada masyarakat; (3) penyediaan anggaran pengelolaan sungai dan pelibatan masyarakat dalam pengamanan sungai; (4) hukuman yang tegas bagi pelaku cemaran air sungai.
