Aceh merupakan salah satu provinsi dengan kekayaan sumber daya alam, termasuk keterdapatan batuan metamorf yang berpotensi untuk menjadi bahan dasar pembuatan pupuk. Penelitian ini bertujuan mengetahui potensi batuan serpentinit secara optimal. Secara geologi, penelitian ini menargetkan Formasi Komplek Indrapuri (Tuic) berdasarkan keterdapatannya batuan serpentinit pada Formasi tersebut. Penelitian ini bertujuan untuk mengetahui bagaimana kondisi geologi daerah penelitian melalui pemetaan geologi. Selain itu, dilakukan metode analisis X-Ray Flourescence pada batu serpentinit dengan tujuan mengetahui komposisi pada batuan serpentinit. Penelitian ini dilakukan dengan tiga metode penelitian yaitu pemetaan geologi, analisis petrografi serta analisis X-Ray Fluorescence. Pada pemetaan geologi dilakukan dengan mengamati 7 satuan batuan yang ditemukan pada lokasi penelitian meliputi satuan endapan konglomerat (Qh), satuan konglomerat (QTps), satuan batupasir karbonatan (QTps), satuan batupasir tufan (Tuic), satuan batu serpentinit (Tuic), satuan batu gamping (Tlm), dan satuan batu basalt (Tlm). Pada saat pengamatan bentang alam di lokasi penelitian didapati bentang alam berupa bentang alam denudasional (D3 & D5), bentang alam struktural (S4), bentang alam vulkanik (V14) dan bentang alam fluvial (F1 & F3). Hasil analisis X-Ray Fluorescence pada batu serpentinit di Formasi Komplek Indrapuri (Tuic) menunjukkan komposisi berat massa unsur pada batu serpentinit dengan unsur dominan magnesium oksida (MgO) memiliki persentase 52,96% dan unsur silika (SiO2) memiliki persentase 41.83 %. Selain unsur dominan, terdapat unsur minor yaitu Fe2O3 memiliki persentase 4.991 %.

Aceh is a province with rich natural resources, including the presence of metamorphic rocks that have the potential to be used as basic materials for fertilizer production. This study aims to determine the optimal potential of serpentinite rocks. Geologically, this study targets the Indrapuri Complex Formation (Tuic) based on the presence of serpentinite rocks in the Formation. This study aims to determine the geological conditions of the research area through geological mapping. In addition, the X-Ray Fluorescence analysis method was carried out on serpentinite rocks to determine the composition of serpentinite rocks. This study was conducted using three research methods, namely geological mapping, petrographic analysis, and X-Ray Fluorescence analysis. In geological mapping, seven rock units were observed at the research location, including conglomerate sedimentary units (Qh), conglomerate units (QTps), carbonate sandstone units (QTps), tuffaceous sandstone units (Tuic), serpentinite units (Tuic), limestone units (Tlm), and basalt units (Tlm). During the observation of the landscape at the research location, the landscape was found to be in the form of denudational landscapes (D3 & D5), structural landscapes (S4), volcanic landscapes (V14) and fluvial landscapes (F1 & F3). The results of X-Ray Fluorescence analysis on serpentinite rocks in the Indrapuri Complex Formation (Tuic) showed the composition of the mass weight of elements in serpentinite rocks with the dominant element magnesium oxide (MgO) having a percentage of 52.96% and silica (SiO2) having a percentage of 41.83%. In addition to the dominant elements, there are minor elements, namely Fe2O3 having a percentage of 4.991%.
