        abstract = {Pulau Maniang memiliki potensi sumber daya nikel (Ni) dan mineral asosiasinya yaitu Mn, Co dan Al. Pulau Maniang secara administratif termasuk wilayah Kabupaten Kolaka, Provinsi Sulawesi Tenggara dan merupakan tempat terbentuknya pengayaan unsur-unsur yang dapat digunakan sebagai bahan baku baterai pada zona limonit. Tujuan penelitian adalah untuk mengetahui terjadinya pengkayaan unsur Ni, Mn, Co dan Al lebih berkembang pada zona limonit jenis yellow limonite ataukah red limonite.         Metode penelitian dengan melakukan penelitian lapangan dan laboratorium. Penelitian lapangan berupa pengeboran dan deskripsi megaskopis sedangkan laboratorium berupa analisa kimia serta melakukan analisis histogram, scatter plot, dan ternary data yang diperoleh dari analisis geokimia terhadap unsur nikel (Ni), mangan (Mn), kobalt (Co), dan aluminium (Al). Secara megaskopis limonit di Pulau Maniang dibagi menjadi dua yaitu jenis red limonite dan yellow limonite. Hasil penelitian menunjukkan bahwa red limonite mengandung hematite sebesar 40\%, goethite 10\%, dan mangan 5\%. Yellow limonite mengandung goethite sebesar 25\%, hematite 15\%, dan serpentin 5\%. Sebaran kandungan Ni pada red limonite 0,3\%-0,7\% sedangkan pada yellow limonite 0,7\%-1,50\%. Dengan demikian dapat disimpulkan bahwa yellow limonite mengandung Ni yang lebih potensial dibanding red limonite. Penyebaran kedua jenis limonit ini adalah pada kelas lereng datar (08\%) sampai curam (25-45\%).

  Maniang Island has potential resources of nickel (Ni) and its associated minerals, namely Mn, Co and Al. Administratively, Maniang Island belongs to the Kolaka Regency, Southeast Sulawesi Province and is a place for the formation of enrichment elements that can be used as raw material for batteries in the limonite zone. The aim of the study was to determine whether the enrichment of Ni, Mn, Co and Al elements was more developed in the yellow limonite or red limonite type limonite zone.        The research method by conducting field and laboratory research. Field research is in the form of drilling and megascopic descriptions while the laboratory is in the form of chemical analysis as well as analyzing histograms, scatter plots, and ternary data obtained from geochemical analysis of the elements nickel (Ni), manganese (Mn), cobalt (Co), and aluminum (Al) . Megascopically, limonite on Maniang Island is divided into two types, namely red limonite and yellow limonite. The results showed that red limonite contained 40\% hematite, 10\% goethite and 5\% manganese. Yellow limonite contains 25\% goethite, 15\% hematite and 5\% serpentine. The distribution of Ni content in red limonite was 0.3\%-0.7\% while in yellow limonite it was 0.7\%-1.50\%. Thus it can be concluded that yellow limonite contains Ni which is more potent than red limonite. The distribution of these two types of limonite is on flat slopes (0-8\%) to steep (25-45\%).
