Analyzing peer-reviewed literature on augmented reality (AR) is vital for future research and development. The objective of the current study was to assess research activity on AR with an emphasis on education and physics education. A bibliometric method was applied using SciVerse Scopus. The study period was from 1978 to 2021. The search query found 3393 documents in the AR-related education literature and 97 in the AR-related physics education literature. The bibliometric analysis result shows that the similarity of the results of visualization of AR in education networks with AR in physics education is: that research focuses on students, and the majority is integrated with virtual reality. This research has implications for providing insight to the next researcher in finding gap research and novelty in the field of AR in education and physics education.

Sebuku is occupied by serpentinized ultramafic (peridotite) rocks, gabbro, and chert which are ophiolite series formed in the oceanic crust, in the middle occupied by tuff and claystones. The purpose of this study was to determine the distribution pattern of iron ore deposits. The research area illustrates that the distribution of Fe elements with high levels of >48% is concentrated in the northeast-southwest part, while Fe elements with levels of <48% are concentrated in the southwest-northwest part of the west. Based on the topographic classification of the research area. The pattern of mineralization follows the structural pattern that occurs, where the lateralization of the source rock is intensive in the crushing zone around the structure that forms the main structure and minor structure. This destruction zone serves as an effective water infiltration medium to accelerate the washing process which forms supergene enrichment zones. The pattern of distribution of mineralization is relatively Northeast-Southwest which in some places is characterized by the straightness of the ridge or morphology with more contrasting and prominent zones on the lidar mosaic map.

“…Di Sulawesi Selatan tepatnya di sepanjang pantai Tanjung Bayang ditemukan pasir pantai yang penyebarannya memanjang sepanjang arah pantai. Namun kadar Fe nya belum layak untuk diolah atau dijual lebih lanjut, baik untuk pemanfaatan pasir besi lokal sebagai bahan baku industri semen maupun untuk industri besi dan baja maupun untuk industri lainnya [7]. Oleh karena itu, perlu dilakukan penelitian tentang "Benefisiasi pasir besi Tanjung Bayang dengan menggunakan magnetic separator" di Tanjung Bayang, Kecamatan Tamalate, Kota Makassar, Sulawesi Selatan.…”

Pemanfaatan bahan galian tambang berupa pasir besi di Indonesia cukup bervariasi. Pada industri semen dan industri pembuatan baja, pasir besi dalam bentuk bahan mentah atau raw material dimanfaatkan sebagai bahan campuran. Di Sulawesi Selatan tepatnya di sepanjang Pantai Tanjung Bayang ditemukan pasir pantai yang penyebarannya memanjang sepanjang arah pantai. Namun kadar Fe nya belum layak untuk diolah atau dijual lebih lanjut, baik untuk pemanfaatan pasir besi lokal sebagai bahan baku besi dan baja maupun untuk industri semen. Penelitian ini dilakukan dengan tujuan untuk mengetahui geokimia pasir besi menggunakan X-Ray Diffraction (XRD) dan X-Ray Fluorescence (XRF), menentukan kecepatan putar drum optimum dan mengetahui recovery yang optimum terhadap peningkatan kadar Fe pasir besi menggunakan Magnetic Separator. Metode penelitian dilakukan secara induktif menggunakan perpaduan antara penelitian kuantitatif dengan kualitatif, kesimpulan diperoleh dari perpaduan antara data lapangan dengan data hasil uji laboratorium. Hasil analisis XRD (X-Ray Diffraction) menunjukkan sampel pasir besi tersusun oleh mineral diopside (MgCaSi2O6), quartz (SiO2), magnetite (Fe3O4) dan hematite (Fe2O3). Hasil analisis X-Ray fluorescence spectrometry (XRF) memiliki Fe2O3 27,93%, SiO2 36,86%, Al2O3 20,317%, CaO 9,78%, TiO2 3,34%, MnO, K2O, V2O5, Cr2O3, ZrO2, SrO, ZnO, dan P2O5 masing-masing di bawah 1%. Hasil menunjukan bahwa persen berat menggunakan magnetic separator type dry-low intensity drum dengan variasi kecepatan putar 200, 250 dan 300 rpm masing-masing 79,25%; 44,17% dan 46,04% sedangkan kadar Fe2O3 masing-masing 29,98%, 49,08% dan 44,15% dengan recovery 85,08%; 77,62% dan 72,78%. Recovery Fe2O3 optimum diperoleh pada kecepatan 250 rpm.
