Abstract

Penelitian ini bertujuan untuk mengetahui karakteristik zeolit alam Toraja dan kemampuannya dalam menurunkan jumlah ion Ca2+ pada air  tanah (sumber mata air Citta kabupaten Soppeng). Penentuan jumlah ion Ca2+ menggunakan fotometri nyala, waktu kontak optimum menggunakan metode batch dengan variasi waktu yaitu 20, 40, 60, 80 dan 100 menit, penentuan kapasitas tukar kation (KTK) dengan variasi konsentrasi ion Ca2+ 120, 150, 180, 210, 240 ppm, dan penurunan jumlah ion Ca2+ menggunakan metode pertukaran ion yang berlangsung dengan model aliran dari atas ke bawah.  Hasil penelitian menunjukkan bahwa jumlah ion Ca2+ dalam air yang berasal dari Citta sebesar 129,53 ppm, waktu kontak optimum tercapai pada menit ke-60, KTK terhadap ion Ca2+  sebesar 13,35 mEq/100 gr zeolit, dan zeolit alam Toraja dapat menurunkan jumlah ion Ca2+ hingga 104,29 ppm pada perbandingan zeolit : air sebesar 1:200.Kata Kunci: ion Ca2+, Zeolit, KTK, Fotometri

Abstract

This study aimed to isolation and characterization the flavonoid compounds in plants ant nest (M. tuberose) from Village District Majannang Parigi, Gowa regency in South Sulawesi. This research was conducted through several phases, namely: sample preparation, isolation and characterization. Isolation starting from extraction, followed by fractionation and purification, among others, by recrystallization, then performed characterization, which among others, performed with test reagent 1% AlCl3 in ethanol, FeCl3 and with benedict, thin layer chromatography and melting point test. Results of research conducted on the basis of several characterization, obtained pure compounds form crystals amount of 220 mg of yellowish white, needle-shaped, with melting point 116-117 º C, Rf with eluen BAA by 71, reacted positively to the reagent 1% AlCl3 in ethanol which is marked yellow spots occur and with reagent benedict give a light blue under UV light, reasonably suspected that the compound obtained is a type of flavone of flavonoid compounds.
