“…The XRD results of this study are in agreement with the findings of Rianna et al. [ 33 ], who characterised sea sand on the west coast of Sumatra. Elements such as C, O, Al, Si, Ca, Mn, and Fe were the dominant elements found in sea sand.…”

Aluminium matrix composites (AMCs) are widely used in various applications because of their excellent properties; however, their lightweightness limits their broad application scope. Various ceramic compounds are used as reinforcements in AMCs, such as Al 2 O 3 , SiC, ZrO 2 , and TiO 2 . However, the use of ceramic compounds results in high production costs in AMC manufacturing. Thus, the substitution of reinforcement particles with various organic and industrial waste reinforcements is required. In line with the research trend of using industrial waste materials such as rice husk ash, red mud, and fly ash, this study uses sea sand as an AMC reinforcement. Sea sand is used because it primarily contains SiO 2 and Fe 3 O 4 ceramic compounds and, thus, can be used as a reinforcement. This study aims to determine the physical and mechanical properties of an AA6061–sea sand composite. Sea sand was subjected to electroless coating to increase its wettability before the stir-casting process. The as-prepared composite was manufactured by the stir-casting method upon the addition of 2–6 wt% sea sand. Composite characterisation was carried out through Brinell hardness and tensile tests. The results showed that the electroless-coated composites possessed lower porosity and, therefore, higher hardness and ultimate tensile strength than the non-electroless-coated composites.

“…Another study confirmed that the iron sand deposit in Java was derived from denudation of andesite and old andesite formation enriched in magnetite and ilmenite minerals [9]. Several studies of iron sand from Sumatera revealed the magnetite minerals were also dominant, hence lower magnetic properties [10,11].…”

In this study, we investigated the mineral content and magnetic properties of river iron sand from Jayapura, Papua. The iron sand was collected from the Waimbow River in the Waibu District, whereas the bulk samples were extracted using a permanent magnet. The extracted iron sand was characterized using X-ray fluorescence and X-ray diffractometer to identify the elemental composition and structural phase. Meanwhile, the vibrating sample magnetometer was also applied to characterize the magnetic properties. The results show that the iron sand contains magnetite as a major mineral, with soft magnetic properties. The hysteresis curve shows that the iron sand has a high saturation magnetization of 27.8 emu/g, remanent magnetization of 2.34 emu/g, and coercive field of 21.3 Oe. These results also indicate that the iron sand formation in northern Papua was mainly due to lithogenic factors.

“…Endapan pasir besi di Indonesia telah dikenal menyebar di sepanjang pesisir Sumatra, Jawa, Pulau Sunda Kecil, Sulawesi dan Nusa Tenggara Barat (Nugraha et al, 2016) dan kepulauan Maluku (Fakhrurrozi, 2015). Pasir besi yang berasal dari pantai maupun sungai ini, memiliki kandungan besi seperti besi oksida hematite (Fe2O3) dan magnetite (Fe3O4) serta senyawa yang lain seperti Fe, Zn, dan Ni (Fitria & Ramli, 2017), titanium (Rianna et al, 2018). Kandungan yang banyak pada pasir besi ini dapat digunakan di bidang perindustrian seperti sebagai bahan campuran untuk membuat semen agar memiliki kualitas yang baik, serta digunakan dalam pembuatan tinta serta berpotensi sebagai bahan magnet dalam pembuatan keramik (Togibasa, 2019).…”

Penelitian ini bertujuan untuk mengetahui perbandingan kandungan Fe dan karakteristik sifat listrik pasir besi sungai dan laut yang disintesis di Kecamatan Pringgabaya. Sampel pasir besi sungai dan laut kemudian dipisahkan menggunakan magnet permanen, setelah itu dicuci menggunakan aquades dan di keringkan selama 2 jam pada temperatur 2000C. karakterisasi material pasir besi sungai dan laut kemudian di lakukan menggunakan AAS (Atomic Absorption Spektrometri), 2 titik probe, dan LCR meter untuk mengukur konstanta dielektrik. Hasil karakterisasi menunjukan bahwa pasir besi sungai dan laut Kecamatan Pringgabaya. Menunjukan adanya perbandingan kandungan mineral, resistivitas dan konstanta dielektrik, kandungan mineral pasir besi sungai lebih besar dibandingkan dengan pantai berkisar dari 9,03 % - 9,8 %, nilai resistivitas sungai dan pantai akan naik pada jarak 10 meter yaitu sebesar 11×104 Ωm dan 10,9×104 Ωm dan konstanta dielektrik sungai dan pantai akan naik pada jarak 10 meter yaitu 13,88×104 dan 15,22×104. Dari hasil tersebut dapat dilihat bahwa adanya perbandingan kandungan mineral sungai dan pantai. Hal ini disebabkan karena adanya pengendapan Fe pada sungai yang menyebabkan kandungan mineral pasir besi sungai lebih besar daripada pantai. pada pengukuran resistivitas dan konstanta dielektrik menunjukan perbandingan nilai resistivitas dan konstanta dielektrik pantai dan sungai. Hal ini disebabkan karena semakin jauh jarak pengambilan sampel nilai resistivitas dan konstanta dielektrik semakin besar, disebakan pasir yang dari sungai setelah mengalir menuju pantai akan teresebar rata dan diikuti percampuran kandungan mineral yang lain, adanya percampuran kandungan Fe dan unsur yang lain menyebabkan nilai resistivitas dan konstanta dielektrik pasir besi pantai lebih banyak karena akan mengandung sifat logam yang mudah menghantarkan arus listrik.
