The synthesis of CuCrO2 crystals by mixing CuO and Cr2O3 has been carried out using the solid reaction method at a temperature of 1200 0C. The characterization of the structure used XRD and analyzed using GSAS software. The results of characterization using XRD showed that no other phase occurred. This is evidenced by the absence of other phases from the results of refinement of measurement data with reference data and a value of χ 2 which is 1.222. The lattice parameter values resulting from the refinement of the CuCrO2 X-ray diffraction pattern are a = b = 2.9715 Å and c = 17.1104 Å with a cell volume of 130.584 Å 3. In addition to the lattice parameter values, the distance between atoms was also obtained, both Cu - O, Cr - Cr, and Cr - O.

“…After that, the Kebon Kongok TPA well water quality was measured using heated iron sand. The healthy water quality parameters measured included temperature, pH, and conductivity using the COM-600 Water Quality Tester [19]. The data obtained will be analyzed descriptively and presented in tables and diagrams.…”

Research has been carried out on the synthesis of river sand-based nanosilica magnetic material to improve water quality by utilizing iron sand taken from four rivers in the Lombok island region as a natural material for the water filtration process, this study aims to determine whether the iron sand nanosilica magnetic material able to improve the quality of well water or not. This study uses an experimental method where iron sand has gone through the coprecipitation process and the water quality parameters measured are temperature, pH and conductivity. The measurement results showed that well water after being mixed with iron sand decreased for temperature and conductivity parameters and increased for pH parameters. Of the three parameters, only one parameter does not meet the water quality standard requirements, namely the pH value before being mixed with iron sand which is below the standard, which is 6.32. However, after the well water was mixed with the four samples of river iron sand, the pH value increased to 7.99, 7.85, 7.75, and 8.00 so that it was able to meet water quality standards for pH parameters.

“…Pengukuran dengan menggunakan PSA dilakukan untuk mengukur ukuran partikel sampel dan bukan mengukur ukuran butir karena pengukuran ukuran butir dapat dilakukan dengan menggunakan XRD [13]. Dengan mengetahui ukuran partikel maka dapat dihubungkan dengan banyaknya konsentrasi Fe yang terkandung dalam satu sampel.…”

“…Semakin besarnya konsentrasi Fe akibat berkurangnya ukuran partikel disebabkan karena semakin kecil ukuran partikel maka akan semakin banyak batas butir di dalam sampel. Akibatnya konsentrasi Fe dalam sampel akan semakin besar seiring dengan berkurangnya ukuran partikel[13].…”

Telah dilakukan sintesis pasir besi berbasis pasir besi Pantai Telindung dengan menggunakan metode solid state reaction (SSR) dan copresipitasi. Sampel kemudian dikarakterisasi ukuran partikelnya menggunakan Pastikel Size Analyzer (PSA) dan konsentrasi Fe diukur menggunakan Atomic Absorption Spectroscopy (AAS). Karakterisasi sifat listrik meliputi konstanta dilektrik dan resistivitas. Konstanta dielektrik diukur menggunakan metode plat sejajar sedangkan resistivitas diukur menggunakan metode 2 titik probe. Ukuran partikel sampel yang disintesis dengan menggunakan metode SSR masih dalam ukuran micrometer yaitu sebesar 1,34 µm sedangkan ukuran partikel dengan menggunakan metode copresipitasi sudah mendekati ukuran nanometer yaitu sebesar 210 nanometer. Konsentrasi Fe dalam sampel sebesar 8,7 ppm pada sampel yang disintesis dengan menggunakan metode metode SSR sedangkan konsentrasi Fe pada sampel yang disintesis dengan menggunakan metode copresipitasi sebesar 12,9 ppm. Nilai konstanta dielektrik sampel yang disintesis dengan metode SSR sebesar 9,41 nilai konstanta dielektrik sampel yang disintesis dengan metode copresipitasi yaitu sebesar 14,22. Nilai resistivitas juga memiliki pola yang sama dengan konstanta dielektrik dimana nilai resistivitas sampel yang disintesis dengan metode SSR sebesar 0,078 Ωm. Sedangkan nilai resistivitas sampel yang disintesis dengan menggunakan metode copresipitasi sebesar 0,092 Ωm.
