Iron sand was widely used in various fields such as in the manufacturing of magnets, cement, and steel. Iron sand has the main composition of iron oxide and several impurities of oxides. To remove these impurities, iron sand needs to be washed with acidic solution such as HCl solution. This study aims to minimize impurities in the magnetic material of Lansilowo iron sand. Iron sand was prepared using an external magnet to obtain magnetic material. The magnetic material was washed using distilled water and 0.5 M HCl solution. The drying process was carried out at 80oC for 24 hours. Magnetic material was crushed, weighed, and characterized. Material characterization was carried out using X-Ray Fluorescence (XRF), Fourier Transform Infrared (FT-IR) Spectrophotometer, and X-Ray Diffractometer (XRD). The Characterization results showed that washing of magnetic material using H2O-HCl 0.5 M was able to increase the percentage of Fe element composition in Lansilowo iron sand. The iron oxide contained in Lansilowo Iron Sand remains magnetite. The washing the iron sand magnetic material using 0.5 M HCl solution succeeded in removing impurities such as Mg, Pr, K, Cl, P, S, Co, Ce, and Sn as well as reducing the percentage of the Si and Al elements.The washing magnetic material using 0.5 M H2O-HCl produced higher XRD intensities than those washed with H2O. The washing magnetic material with 0.5 M H2O-HCl was result particle size of 37,70 ± 4,62 nm  and crystallinity of 53.12%.Pasir besi banyak dimanfaatkan dalam berbagai bidang seperti pada industri pembuatan magnet, semen, dan baja. Pasir besi memiliki kandungan oksida besi dan beberapa oksida pengotor. Untuk menghilangkan oksida-oksida pengotor tersebut, pasir besi perlu dicuci dengan larutan asam seperti larutan HCl. Penelitian ini bertujuan untuk meminimalisir oksida-oksida pengotor pada material magnetik pasir besi Lansilowo. Pasir besi dipreparasi menggunakan magnet eksternal untuk mendapatkan material magnetik. Material magnetik dicuci menggunakan akuades dan larutan HCl 0,5 M. Proses pengeringan dilakukan pada suhu 80oC selama 24 jam. Material magnetik digerus, ditimbang, dan dikarakterisasi. Karakterisasi material dilakukan menggunakan X-Ray Fluorescence (XRF), Fourier Transform Infrared (FT-IR) Spectrophotometer dan X-Ray Difraktometer (XRD). Hasil karakterisasi menunjukkan bahwa pencucian material magnetik dengan menggunakan H2O-HCl 0,5 M mampu meningkatkan persentase komposisi unsur Fe material magnetik pasir besi Lansilowo. Oksida besi yang terkandung dalam Pasir Besi Lansilowo tetap magnetit. Pencucian material magnetik pasir besi menggunakan larutan HCl 0,5 M berhasil menghilangkan unsur-unsur pengotor seperti Mg, Pr, K, Cl, P, S, Co, Ce, dan Sn serta menurukan persentase komposisi dari unsur Si dan Al.

This study aims to prepare iron sand, determine the type of iron oxide, and determine the effect of washing iron sand with sonochemical methods. Iron sand samples were obtained from Jomblom Beach, Kendal Regency. Iron sand was separated using an external magnet to obtain magnetic material. The magnetic material obtained was washed using distilled water manually stirred and using the sonochemical method. The material was dried at 80 °C. Material characterization was carried out using X-Ray Fluorescence (XRF) to determine the elements contained in iron sand, Fourier Transform Infrared (FT-IR) Spectrophotometer to identify functional groups in iron sand, X-Ray Diffraction (XRD) to find out the crystal size and crystallinity of iron sand, and the Transmission Electron microscope (TEM) to determine the morphology of iron sand. The characterization results showed that the iron sand of Jomblom Beach contained Fe (72.28%), Ti (7.89%), Al (7.00%), and Si (7.60%). The iron oxide contained in the Jomblom Beach iron sand was dominated by magnetite (Fe3O4). Washing iron sand magnetic material using the sonochemical method increased the composition of the element Fe, increased the crystallinity of the magnetic material, prevented aggregation, and reduced the crystal size of the magnetic material. Magnetic material which was washed using the sonochemical method produced 79.47% Fe element, crystallinity 74.94%, and crystal size 52.78 nm.

CaO samples prepared from calcining the powdered waste shells at 1300°C for 4 h were tested the efficiency of humidity adsorption. The samples were characterized via X-ray diffraction (XRD) and Fourier transform infrared analysis (FT–IR) to identify the characteristic of CaO after humidity adsorption test. The results indicate that duck eggshells are highest capable of humidity adsorption while hydration rate of chicken eggshells is rather equal to that of cockle shells, and lowest hydration rate was found with sample prepared from Mussel shells. Therefore, we can conclude that the waste shells are suitable to be use as humidity adsorbent for commercial in the future

Effect of aeration treatment on Methylene Blue (MB) removal using TiO2-Zeolite has been investigated. The TiO2-Zeolite was prepared by mixing activated zeolite and TiO2 in absolute ethanol. This composite was characterized using Fourier Transform Infrared (FT-IR) and X-Ray Diffraction (XRD). The MB removal was monitored spectrophotometrically. The effect of contact time, composite mass, and aeration treatment on MB removal was observed. Characterization results showed that there was interaction between TiO2 and SiO/AlO of zeolite. The observation of aeration treatment using oxygen exhibited significant improving on MB removal.
