| Summary: | Has been studied composition of mountain salt from Krayan, Nunukan, East Kalimantan. This study aims to determine the composition of the minerals contained in the mountain salt. Mountain salt is obtained from wells Krayan District residents were further prepared for analysis using a technique using Atomic Absorption Spectrometer (AAS), further by looking at the pattern of X-ray Diffraction (XRD) and Scanning electron microscopic (SEM). Based on the results obtained AAS has identified mineral deposits include: Na, K, Mg, Al, Cu, Zn, Fe, Ba, and Sr. From the results of XRD shows that the main peak of the salt Krayan shows major peaks for NaCl crystals with impurities such as KCl, CaCl2, MgCl2, and AlCl3. SEM observation showed that morphology of Krayan salt have cube shape which is the shape of NaCl crystals with space group Fm3m and lattice parameter (a) 5.620 Ã…

Abstrak
Telah dilakukan penelitian analisis kandungan garam gunung asal Krayan Kabupaten Nunukan Kalimantan Timur. Penelitian ini bertujuan untuk mengetahui komposisi mineral yang terkandung dalam garam gunung. Garam gunung diperoleh dari sumur warga Kecamatan Krayan yang selanjutnya dipreparasi untuk dianalisis dengan menggunakan menggunakan teknik Spektrometer Serapan Atom (SSA), selanjutnya dengan melihat pola Difraksi Sinar X (XRD), dan Scanning Elektron Microscopy (SEM). Berdasarkan hasil SSA telah diidentifikasi diperoleh kandungan mineral antara lain: Na, K, Mg, Al, Cu, Zn, Fe, Ba, dan Sr. Dari hasil XRD terlihat bahwa puncak utama dari garam krayan tersebut menunjukkan puncak utama untuk Kristal NaCl, dengan impurities antara lain KCl, CaCl2, MgCl2, dan AlCl3. Selain itu hal ini didukung pula oleh pengamatan SEM, bahwa morfologi SEM garam krayan memperlihatkan bentuk kristal kubus yang merupakan bentuk dari Kristal NaCl dengan grup ruang Fm3m dengan panjang kisi kristal 5,620 Ã….
