Abstract

ABSTRACT The research was conducted at the Integrated Laboratory. Indonesian Agricultural Environment Research Institute (IAERI), Jakenan, Pati, Central Java. Treatment for electroplating wastewater samples taken from Talang Subdi-strict, Tegal District, Central Java was managed as chemically that was through the coagulation and flocculation processes. The purpose of this study was to test the effectiveness of coagulant and adsorbent materials in reducing the concentration of electroplating wastewater 0: Experiments used a factorial design in randomized completely block design and three replications. The first factor was the coagulant materials, namely: control, alum (Al2(SO4 xH2O)), sodium bisulphate (NaHSO), and resin anion, while the secondfactor was the adsorbent materials, namely: co~trol, activated carbon, and zeolite. The results showed that all coagulants (sodium bisulphate, alum, and resin anion), adsorbent materials (activated carbon and zeolite) and a combination of both significantly decreased the concentration of e1eclraplaling wastewater Cr more than 50%. Resin anion and its combination with activated carbon as well as with zeolite were very effective in decreasing the concentration of electroplating wastewaler Cr (97-98%). Coagulant and adsorbent combination, resin anion+activated carbon and resin anion+zeolit, had doublefunction that decreased of both Cr consentration and TDS (Total Dissolved Solid) of the concentration of electroplating wastewater.

Keywords: Chromium, coagulant, adsorbent, electroplating, wastewater.


Abstrak

Pelaksanaan kegiatan penelitian dilakukan di Laboratorium Terpadu Balai Penelitian Lingkungan Pertanian, Jakenan, Pati, Jawa Tengah. Pengolahan limbah cair electroplating yang diambil dari Kecamatan Talang Kabupaten Tegal, Provinsi Jawa Tengah dilakukan secara kimia, yaitu melalui proses koagulasi dan flokulasi. Tujuan penelitian ini untuk menguji efektivitas bahan koagulan dan adsorben dalam menurunkan konsentrasi Cr limbah cair electroplating. Percobaan menggunakan rancangan faktorial dalam rancangan acak kelompok dengan tiga kali ulangan. Faktor I adalah bahan koagulan, yaitu kontrol, tawas (Al2(SO4 xH2O))sodium bisulfat (NaHS04), dan anion resin, sedangkan faktor II adalah bahan adsorben, yaitu kontrol, arang aktif, dan zeolit. Hasil penelitian menunjukkan bahwa semua bah an koagulan (sodium bisulfat, tawas, dan anion resin), bahan adsorben (arang aktif dan zeolit) dan kombinasi keduanya nyata menurunkan konsentrasi Cr limbah cair electroplating lebih dari 50%. Anion resin dan kombinasinya dengan arang aktif serta kombinasinya dengan zeolit sangat efektif dalam menurunkan konsentrasi Cr limbah cair electroplating (97-98%). Kombinasi koagulan dan absorben antara anion resin+arang aktif dan anion resin+zeolit berfungsi ganda, selain menurunkan kadar Cr juga menurunkan IDS (Total Dissolved Solid) limbah cair electroplating.

Kata kunci: Kromium, koagulan, adsorben, limbah cair electroplating
