“…PENDAHULUAN 1 igmen besi oksida semakin diminati dibanding pigmen oksida lainnya karena bahan tidak beracun, struktur kimia yang stabil, dan warna yang lebih bervariasi dari kuning, oranye, merah, coklat, hingga hitam (Buxbaum, 2005). Pigmen digunakan sebagai pewarna di banyak keperluan industri yang meliputi konstruksi, plastik, pelapis, cat, kertas, dan lainnya dengan industri konstruksi dan cat memegang sepertiga dari permintaan global pada tahun 2015.…”

Pengembangan industri kimia sangat penting dikarenakan dapat mengurangi pengeluaran devisa negara untuk mengimpor bahan-bahan yang dibutuhkan oleh penduduk Indonesia. Dengan adanya pengembangan di dunia industri kimia, diharapkan Indoensia dapat menjadi negara yang mandiri karena tidak lagi bergantung pada industri-industri diluar negeri. Salah satu industri yang perlu dikembangkan di Indonesia adalah pigmen besi oksida. Permintaan pigmen besi oksida secara global di industri konstruksi, cat, dan plastik mengalami peningkatan, sehingga diperkirakan akan mendorong pertumbuhan pasar selama delapan tahun ke depan. Dimana, pasar pigmen besi oksida global didominasi oleh Asia Pasifik dan menyumbang 40,7% dari industri pada tahun 2015 karena infrastruktur yang tumbuh dan industrialisasi yang pesat, terutama di negara-negara seperti China dan India. Pabrik Pigmen Besi Oksida dari Besi Oksida yang berasal dari limbah direncanakan mulai dibangun pada tahun 2022 dengan kapasitas 5060,33 ton/tahun. Dikarenakan pabrik pigmen menggunakan bahan baku yang berasal dari produk samping PT. X, maka lokasi yang dipilih adalah di dekat PT. X yaitu di Tayan, Kalimantan Barat. Pabrik pigmen besi oksida yang didirikan akan dioperasikan selama 330 hari selama satu tahun. Proses produksi akan dibagi menjadi beberapa tahap yaitu pre-treatnent, presipitasi, flitrasi, drying, milling. Dari perhitungan analisa ekonomi didapatkan IRR sebesar 37,04%, POT selama 4,2 tahun. Kata Kunci-pigmen, pasir besi, besi oksida.

“…R. M. Cornell and U. Schwertmann (2003) explained that structure, size, and shape of particles could affect the color of hematite. Bilalodin et al (2015) on the research explained that iron oxide of 926.4 nm particle size colored black, iron oxide of 72.2 nm particle size colored red, and iron oxide of 349 nm particle size colored yellow. Each iron oxide compound has different morphology distinguishable from one another.…”

Hematite coated PEG was synthesized by the sonication-calcination method. A variation of Na2CO3 is investigated to know the effect on structure and morphology. Characterization of samples are using X-ray fluorescence, X-ray diffraction, Scanning electron microscopy, and color reader techniques. XRF data showed that iron is the highest element in the precursor. The X-ray diffraction data confirm that Fe(OH)3, α-FeOOH, and Fe3O4 established at the sonication stage are then transformed into the α-Fe2O3 phase after calcination. The X-ray diffraction data also was found that α-Fe2O3 at 0.5 M formed with the highest crystallinity degree. The scanning electron microscopy showed that the particle's shape is spherical, bar-shaped, and aggregate. However, the distribution of particles is not uniform and still displays agglomeration. The Color reader shows the highest degree of lightness obtained is at 1 M variation.

“…Meanwhile, goethite synthesis at 70°C produced particle size around 0.318 μm with octahedral structure. Bilalodin et al [6] performed goethite synthesis by precipitation method, producing goethite (Fe-OOH) of orthorhombic structure with uniform shape about 0.35 μm and the colour test result came out as L* = 66.76, a* = 14.84, b* = 49.95 [6]. The aim of this research was to find out the effect of synthesis temperature on the structure, colour and morphology of product synthesized through precipitation method.…”

“…The world consumption of yellow pigment has reached 69,000 tons in 2015 and it continues to increase annually [5]. The highest consumption arises from its use as a widely applied colorant in construction products, paint, coating, animal feed, glass, ceramic and other uses [6]. Yellow iron oxide is composed of goethite (-Fe-OOH) with orthorhombic crystal system.…”

Lathe waste contains high iron content potential to be further processed into goethite pigment. The purpose of the research was to determine the effect of synthesis temperature on the structure, colour values, and morphology of goethite pigment. The synthesis was conducted with temperature variations of 60, 70, 80and 90°C. The XRD diffraction pattern shows that crystal structure of the product of all synthesis temperatures are goethite (α-Fe-OOH) with orthorhombic structure. The crystal size of the pigment ranges between 11.17 – 12.32 nm. Colour value analysis shows that product of 70°C synthesis temperature exhibits the highest lightness value about 40.5. Based on SEM-EDX imaging, the morphology of the samples is not uniform and forming agglomerates. Traces of impurities were detected, such as C and Na.
