Abstract


Kandungan mineral besi pada alam menjadi topik yang menarik untuk dikaji terkait peran pentingnya secara ekonomi. Keberadaan magnetite pada sedimen di suatu wilayah perairan dapat juga digunakan sebagai fingerprint dari proses transport sedimen. Penelitian ini ditujukan untuk mengamati sejumlah parameter butiran sedimen untuk mendapatkan gambaran pola distribusi sedimen yang terjadi pada daerah Labuhan Haji Timur, Aceh Selatan. Pengambilan sampel sedimen dilangsungkan pada November 2015 menggunakan metode coring. Sebanyak empat stasiun dipilih untuk mewakili kawasan perairan Labuhan Haji timur, yang terdiri dari daerah aliran sungai, muara, dan pantai. Sejumlah analisis yang dilakukan adalah ukuran butiran rata-rata, bentuk partikel, dan kandungan kimia penyusun sedimen. Analisis kandungan kimia dari sampel sedimen dilakukan pada  Laboratorium Sentral Mineral dan Material Maju, FMIPA Universitas Malang menggunakan  X-Ray Fluorescence (XRF), dimana sebelumnya sampel dari setiap stasiun dipilah berdasarkan ukuran halus (lebih kecil dari 0,5 mm) dan kasar (lebih besar dari 0,5 mm). sampel sedimen yang berasal dari pantai dan muara memiliki modus distribusi ukuran sedimen pada fraksi pasir sangat halus, sedangkan modus pada daerah aliran sungai berada pada fraksi pasir sangat kasar. Magnetite ditemukan pada setiap lokasi sampling, persentase tertinggi berada pada kawasan muara. Analisis bentuk butiran magnetite menunjukkan bentuk yang lebih angular pada daeah aliran sungai dan menjadi lebih rounded pada kawasan pantai. Disimpulkan bahwa kandungan magnetite yang terdapat pada kawasan pantai di Labuhan haji Timur ditransportasikan melalui aliran Sungai Peulumat.
