“…Secara geologi sumber daya mineral tersebut tersebar hampir di setiap pulau di Indonesia mulai dari Jawa, Sumatera, Kalimantan hingga Sulawesi. Sehingga perkiraan jumlah cadangan zeolit alam Indonesia sangatlah melimpah [1]. Zeolit alam terbentuk karena adanya proses kimia dan fisika yang kompleks dari batuan yang mengalami berbagai macam perubahan di alam.…”

Zeolit merupakan kristal aluminosilikat yang mempunyai struktur pori yang teratur dan memiliki luas permukaan tinggi. Adsorben zeolit akan diaktivasi dengan metode mekanokimia dengan tujuan untuk menghilangkan pengotor-pengotor yang ada pada zeolit sehingga kemampuan adsorpsi nya bertambah. Mekanokimia merupakan proses pemanfaatan energi mekanik untuk merubah struktur bahan sehingga bahan yang dihasilkan memiliki luas permukaan yang lebih besar dan juga memiliki kemampuan mengadsorp dengan baik. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh waktu mekanokimia dan konsentrasi Natrium Hidroksida (NaOH) terhadap kualitas adsorben zeolit. Penelitian ini menggunakan metode kuantitatif dengan variabel tetap perbandingan zeolit dengan NaOH 1:4 (b/v) dan variabel berubah waktu mekanokimia 30; 60 menit dan konsentrasi NaOH 1; 2; 3 M. Analisis yang dilakukan pada pengujian adsorben zeolit adalah kadar air dan kadar abu. Hasil terbaik yang diperoleh dari kedua pengujian tersebut adalah kadar air sebesar 0,5% dan kadar abu sebesar 1,941%. Hasil tersebut menunjukkan bahwa adsorben zeolit memiliki kualitas yang baik.

“…Indonesian natural zeolites are scattered in 47 locations [25]. Geologically, zeolites are spread from the islands of Sumatra, Java, Kalimantan, Sulawesi [26], and Nusa Tenggara [27][28][29]. Indonesia has natural zeolite reserves of around 447,490,160 tons [29].…”

“…The most common zeolites in Indonesia are analysis, chabazite, clinoptilolite, heulandite, erionite, ferrierite, laumontite, mordenite, and flipside [30]. Natural zeolite from Sukabumi has three mineral compositions, namely quartz, mordenite, and clinoptilolite, but tends to be mordenite zeolite [26,30]. Malang natural zeolite and Gunung Kidul natural zeolite have a mordenite structure [31].…”

Environmental and health problems related to water pollution by bacteria are a big challenge in the water treatment process. This pollution is caused by industrial development and increased population growth. Bacterial removal methods in water are continuously developed to find an efficient water treatment process. Zeolite has the potential to be an adsorbent used in the water treatment process. Zeolite has been widely used in adsorption and catalytic processes. Zeolite is a porous alumina silicate consisting of silicon, aluminium, and oxygen in its framework. Zeolite cations can be exchanged with monovalent or divalent ions. Zeolite does not have antibacterial activity, so it should combine with metal cations such as Ag, Cu, Zn, and Fe. Metal active that loaded into zeolite framework is a solution to improve the zeolite performance for bacteries removing in water. The impregnation method is the most widely used for the metal loading process into zeolite framework, because of its simple and economical process. This review will discuss natural and synthetic zeolites, types of metal, impregnation process, the antibacterial activity of metal impregnated zeolite, bacterial attack mechanism, and antibacterial application of metal impregnated zeolite in water.

Zeolite as a catalyst can increase its activity by carrying out physical and chemical activation processes. Physical activation can be activated by reducing the size of the zeolite through grinding and sieving methods, from the physical activation process it can increase the surface area of the zeolite. In this study, zeolite was chemically activated by acid activation method by immersing natural zeolite with HCl and HF. The oxide compound in the activated zeolite was characterized using XRF. The activated zeolite was used to reduce the free fatty acid levels with variations in the addition of 7 to 10 grams of zeolite. The content of free fatty acids is then compared with the quality requirements of cooking oil according to SNI 01-3741-2013. The results of the research conducted showed that there were differences in the content of oxide compounds in zeolite before and before activation with differences in SiO2 content, namely 69.4% before activation and an increase of 82.1% after activation. The results of the state test including physical properties, odor, and taste tests of used cooking oil that have been purified indicate that used cooking oil that has been purified meets the quality requirements of cooking oil based on SNI 01-3741-2013. Used cooking oil that has been purified has a normal taste, does not smell. rancid and yellow. The content of free fatty acids meets the requirements of SNI 01-3741-2013 for all variations of the addition of zeolite with the highest decreasing value obtained at the addition of 10 g of zeolite with a free fatty acid content value of 0.22%.
