“…So far, residents have taken sand from the river to sell it as building materials at relatively low prices. Even though there are many uses for iron sand, iron sand can be used as a microwave absorption material because it contains iron oxide (Fe 2 O 3 and Fe 3 O 4 ) [9] and silica oxide (SiO2) as well as other compounds such as Fe, Ni, and Zn in small amounts [7], [10], [11]. Iron sand also has the potential to be a carrier or as a binder to improve the quality of a material, such as manganese dioxide (MnO2) adsorbent, which is widely used for water remediation processes from heavy metals and non-metallic waste [12].…”

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.

“…In addition, Indonesia consists of several islands, one of which is Lombok Island in West Nusa Tenggara (NTB). Lombok island has coastline with length of 2,333 km and 4 river lines which have a lot of natural iron sand that has potential to be developed [3].…”

“…The area on Lombok Island which is suspected to have iron sand is the beach and river in the east Lombok area and Mataram [6]. East Lombok has a river that directly flow into the coastal areas like Telindung [7] and Pringgabaya [3]. This coastal and river sand have very black sand, so they are thought to have a high natural iron sand content.…”

This study aims to analyze the mineral content and morphological characteristics of magnetic minerals based on coastal and river sand. Analysis of minerals content uses Atomic Absorption Spectroscopy (AAS) to determine the content of Fe and Energy Dispersive X-Ray (EDX) to determine the elements of magnetic minerals based on coastal and river sand. While the morphological characteristics were analyzed using Scanning Electron Microscope (SEM). Based on the AAS analysis, magnetic mineral based on coastal sand has higher Fe content (9.03 mg/gram) compared to magnetic mineral based on river sand (8.03 mg/gram). This is also confirmed by EDX analysis where the Fe content of magnetic mineral based on coastal sand is 2.07 ± 0.21%. This value is greater than the Fe content of magnetic mineral based on river sand which cannot be measured by EDX. Morphological analysis using SEM shows that magnetic mineral based on coastal sand has a relatively uniform particle size compared to magnetic mineral based on river sand. The particle size of magnetic minerals based on coastal sand also smaller than magnetic minerals based on river sand. Coastal sand also has finer size compared to river sand. This is because coastal sand sediments are formed due to the energy of sea waves so that they have a smoother structure. While river sand sediments come from limestone deposits that have a fine and coarse structure.
