This research is aimed to recognize the chemical composition, type, and main mineral morphology that are consisted in Batu Angus. The analytical methods used are X-ray Fluorescence (XRF), X-ray Diffraction (XRD), Fourier Transform Infra-Red (FTIR), and Scanning Electronic Microscopic (SEM). The result of the research showed that the chemical composition of Angus stone consists of silicone mineral and iron. The kind of silicone mineral is identified as mineral quartz, cristobalite, and tridymite while the iron mineral is identified as maghemite. The silicone mineral morphology has tetragonal, cubic, orthorhombic, hexagonal, and trigonal geometry shapes.
Characterization and identification of Maitara Island clay have been carried out. This study aims to determine the types of minerals contained in the Maitara Island clay. The analytical methods used include X-Ray Fluorescence (XRF) to determine the chemical composition of Maitara Island clay, X-Ray Diffraction (XRD) for mineralogical analysis of Maitara Island clay, Fourier Transmission Infra Red (FTIR) to determine the types of vibrations that exist between the atoms in clay minerals from Maitara Island, and Scanning Electron Microscopy (SEM) to determine the morphology of clay minerals. XRF analysis showed that silica was the element found to dominate the clay minerals with a percentage of 40.79%. Moreover, the highest oxide component found was SiO2 with a percentage of 87.25%. XRD analysis indicated that the Maitara Island clay minerals are composed of montmorillonite, magmatite, aluminum oxide colondrum, cristobalite, lime, titanium oxide, and hematite. The results of FTIR analysis denoted the presence of silica as silanol and siloxane. SEM images showed angular grains which signified silica as the main component in the clay minerals of Maitara Island
Nickel mining activities at PT. ANTAM North Maluku Nickel UBP is closely related to the production and distribution process. To achieve optimal production, nickel ore is loaded or shipped in accordance with the company's production targets. The study aims to determine the compatibility value of barges and crane loading equipment in the shipping process and to determine the factors that affect the productivity of nickel ore shipments. The research method used is descriptive quantitative method, where the analysis process is based on distribution table data, average values, and percentages. This research was conducted at the Tanjung Buli Site in the MV. shipping process. Lumoso Karunia VIII. In this shipment, the stowage plan target is 55255 tons which must be completed within a maximum of 10 days. The results of the calculation of the compatibility of crane loading equipment in MV. Lumoso Karunia VIII and barge transportation have a match factor value of 0.72 or <1. Factors that affect the decline in the shipping process are work efficiency time, the value of the match factor and rainy time. From the calculation results, the work efficiency time obtained is 65.94% or less efficient. The value of the match factor <1 can conclude that the transportation equipment is busy while the loading equipment has a lot of idle time and rain constraints with an average amount of rain time of 206.6 minutes or 3.44 hours. However, the shipping process can reach the production target within 8 days with the capability of loading equipment productivity reaching 6997.95 tons/day.
Kebutuhan masyarakat akan bahan tambang bertambah seiring dengan pertambahan penduduk. Salah satu potensi bahan tambang golongan C di Kota Ternate terdapat di daerah Jambula berupa bahan galian pasir dan batu (sirtu). Penggalian bahan galian pasir dan batu yang tidak benar akan menimbulkan potensi kecelakaan kerja, selain itu pengambilan bahan galian sirtu yang secara berlebihan juga dapat menimbulkan dampak negatif bagi lingkungan. Untuk itu kegiatan penyuluhan ini dilakukan sebagai bentuk perwujudan Tri Dharma Perguruan Tinggi. Kegiatan ini bertujuan untuk memberikan kontribusi kepada masyarakat sekitar lokasi penggalian mengenai potensi bahan galian sirtu, pengelolaan bahan galian sirtu yang berwawasan lingkungan serta cara penanganan dampak lingkungan. Identifikasi bahan galian sirtu yang dijumpai di lokasi penyuluhan berupa material pasir, batu andesit, pumis, skoria, lithic tuff, tufa lempungan, dan batu lempung. Material ini dapat dimanfaatkan sebagai bahan bangunan dan aggregat. Sedangkan masalah lingkungan yang timbul berupa penggundulan lahan, pencemaran udara, peningkatan kebisingan, kerusakan jalan, peningkatan getaran dan gangguan ekosistem lainnya.
Berbagai dampak yang diakibatkan oleh perkembangan teknologi mampu membuat perubahan dari kepribadian dan perilaku anak. Salah satu dampak negatifnya dari perkebangan teknologi, yaitu berkurangnya budaya membaca pada anak. Untuk itu salah satu dari program kerja Salimah adalah menumbuhkan budaya membaca melalui launching “Pojok Literasi Anak Negeri” dengan tema Baca Buku, Dunia dalam Genggamanmu. Kegiatan ini dilaksanakan pada tanggal 22 Mei 2021 dan bertempat di Kel. Togolobe, Kec. Pulau Hiri, Provinsi Maluku Utara. Tujuan dari kegiatan ini yaitu dapat meningkatkan transfer pengetahuan secara tidak langsung kepada pelajar/anak dan masyarakat serta mengajarkan untuk mengerti tentang arti pentingnya budaya membaca sehingga dapat menumbuhkan kecintaan terhadap buku.
