“…The magnetic field value obtained is then mapped in the contour of the magnetic field anomaly. Magnetic anomalies provide an overview of the non-uniformity of the Earth's magnetic field (Khalil & Santos, 2014;Mariyanto et al, 2018). This non-uniformity is caused by the distribution of magnetic objects that have different properties and characteristics.…”

Lombok island is included in one of the areas prone to earthquakes due to the existence of a subduction zone resulting from the meeting of the Indian-Australian Plate. In this study, the magnetic method was used to determine the subsurface structure of the fault as a research objective. The instrument used in this study consisted of a Proton Precession Magnetometer GSM-19T v7.0 Geomagnet measuring instrument with an accuracy of 0.1 nT to measure the total magnetic field strength. Garmin 60CSx GPS to determine position (latitude and longitude), elevation, time and point of measurement location. The geological compass determines the position and direction of the north-south fault which includes the dip/strike. Some software is also used in processing this geomagnetic data, namely Software (Numeri, Mag2DC, Surfer 9.0) and MS Excel 2013. Based on the results of data processing with 2D and Mag2DC forward modeling, the subsurface structure is obtained in the form of a normal fault, with the average susceptibility value is 0.00605 in Susceptibility (SI) which is a type of limestone. The depth of this normal fault is estimated to be at a depth of 31.5 meters to 74.0 meters.

“…Beberapa studi suseptibilitas magnetik bergantung frekuensi telah dilakukan oleh peneliti (Kirana et al, 2021) melaporkan bahwa sampel tanah lapisan atas perkotaan di Kota Bandung dominan mengandung butir SP dalam sampel (<10%) atau hampir tidak ada butir SP yang memiliki rentang χFD 0,38-4,52% dengan rata-rata 1,89%. Kajian χFD pada sampel sedimen Sungai Surabaya dilakukan oleh (Mariyanto et al, 2018) yang menyatakan bahwa χFD sampel sedimen sungai termasuk pada kategori rendah dan medium. Selain itu juga, χFD pada sampel tanah lapisan atas di berbagai wilayah Jalingo, Negara Bagian Taraba, Nigeria dilaporkan berdasarkan berbagai jenis aktivitas manusia sebagian besar memiliki campuran butir SP dan butir non-SP yang lebih kasar atau butir SP < 0,05μm.…”

Sedimen sungai telah dipelajari secara intensif dalam studi magnetik lingkungan karena sungai merupakan sumber kehidupan bagi hewan dan tumbuhan yang hidup di dalamnya maupun bagi manusia. Magnetik lingkungan merupakan ilmu yang relatif baru dan menjadi cara alternatif dalam mengkaji lingkungan. Oleh karena itu, dilakukan studi tentang pengukuran suseptibilitas magnetik bergantung frekuensi pada sedimen Sungai Tallo di Kota Makassar. Metode yang digunakan adalah metode suseptibilitas magnetik menggunakan alat Bartington Susceptibility Meter MS2B. Hasil menunjukkan bahwa suseptibilitas magnetik pada frekuensi rendah dan tinggi terdapat perbedaan yang tidak signifikan yang berarti sampel sedimen hampir tidak memiliki bulir mineral superparamagnetik. Sampel dominan mengandung butiran non-SP dengan diameter sama atau lebih besar dari 0,03 µm. Korelasi antara suseptibilitas magnetik bergantung frekuensi dan suseptibilitas magnetik pada frekuensi rendah memiliki korelasi positif yang kuat. Peningkatan χLF menyebabkan χFD juga meningkat. Sampel sedimen mengandung butir multi domain (MD) dan superparamagnetik-simple single domain (SP-SSD). Kelimpahan mineral magnetik dipengaruhi oleh adanya aktivitas antropogenik di sekitar sungai.

“…Several other studies have shown that magnetic susceptibility measurement was not only conducted on sediments from rivers [3], [4] but also on sediments from coasts [5], [6] and lakes [7], [8] and other materials such as mineral deposit [9] and guano [10], [11]. Previous studies have shown that frequency-dependent magnetic susceptibility was used to determine superparamagnetic grain content in sediments [12], [13].…”

This article presents measurement data using environmental magnetism method on the bulk surface sediments related to the research article entitled “Heavy metal contents and magnetic properties of surface sediments in volcanic and tropical environment from Brantas River, Jawa Timur Province, Indonesia” Mariyanto et al., 2019. Surface sediments were taken from 20 different locations along Brantas River. In the laboratory, a series of magnetic measurements was conducted on sediment samples i.e. magnetic susceptibility, ARM (Anhysteretic Remanent Magnetization) and IRM (Isothermal Remanent Magnetization). These environmental magnetism data were used to characterize bulk surface sediments in the study area.
