Abstract

Telah 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. 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.

Abstract

A study has been conducted on frequency-dependent magnetic susceptibility in sediments of Lake Tondano, Minahasa, North Sulawesi. This study aims to analyze the types of minerals, grain sizes, and magnetic domains in sediment samples of Lake Tondano. The method used is the rock magnetism method, specifically the magnetic susceptibility parameters. Magnetic susceptibility measurements used a Bartington susceptibility meter that works at two frequencies, namely 470 Hz and 4700 Hz. The results obtained are sediment samples are indicated to contain ferrimagnetic minerals. The grain size distribution in sediment samples is predominantly fine <0.03 µm. The frequency-dependent magnetic susceptibility value χFD% is dominantly more than 2%, indicating the magnetic domain in sediment samples of Lake Tondano are a mixture of superparamagnetic (SP) and single-stable-domain (SSD). Keywords: Magnetic domains; magnetic minerals; lake sediments; magnetic susceptibility; magnetic grain size

Abstract

Indonesia merupakan wilayah rawan gempa bumi karena berada pada jalur Ring of Fire. Kota Tomohon termasuk daerah dengan aktivitas tektonik tinggi, sehingga masyarakat di Kelurahan Kolongan Satu berisiko terdampak gempa. Permasalahan utama adalah rendahnya pengetahuan dan keterampilan mitigasi serta belum adanya pelatihan yang berkelanjutan. Kegiatan ini bertujuan meningkatkan kesiapsiagaan masyarakat melalui pelatihan mitigasi gempa bumi. Metode yang digunakan meliputi tahap pra pelaksanaan, pelaksanaan, serta evaluasi yang melibatkan 20 peserta. Hasil menunjukkan partisipasi mencapai 100% dengan peningkatan pemahaman peserta yang tergolong baik sebesar 90%. Kegiatan ini berhasil meningkatkan pengetahuan dan kesiapsiagaan masyarakat dalam menghadapi gempa bumi. Program berpotensi berkelanjutan melalui penggunaan media edukasi sederhana yang dapat dimanfaatkan secara mandiri oleh masyarakat.

Abstract

Waste from the Antang landfill is estimated to come from various sources, including industry, agriculture, and households. This waste often contains heavy metals and magnetic minerals that can accumulate in the soil, leading to increased magnetic susceptibility. This study aims to analyze the magnetic susceptibility, mineral composition, and morphology of magnetic minerals found in the Antang Makassar landfill. The research utilized several methods: the rock magnetic method for testing magnetic susceptibility, x-ray diffraction (XRD) for mineralogical analysis, and scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS) for characterizing the morphology of magnetic minerals. The results indicated that magnetic susceptibility values ranged from 1.442 x 10-6 m³/kg to 33.523 x 10-6 m³/kg, suggesting the presence of ferrimagnetic minerals in the soil. The morphology of the magnetic minerals in the soil around the Antang Makassar landfill was characterized by various shapes, including nearly octahedral forms, spherules (or imperfect spheres), and angular shapes. The octahedral and angular forms are believed to result from pedogenic processes, while the spherules are associated with anthropogenic processes related to human activities.
