Abstract

Merujuk pada Undang-Undang No. 1 tahun 1970 tentang Keselamatan dan Kesehatan Kerja (K3), laboratorium sebagai sarana pendidikan mempunyai resiko sebagai tempat terjadinya gangguan pada K3. Oleh karena itu perlu adanya pengetahuan yang mendalam mengenai Manajemen K3 bagi guru-guru SMA pengelola laboratorium. Program pengabdian pada masyarakat yang berjudul sosialisasi dan pelatihan manajemen K3 laboratorium bagi 27 guru SMA kota Samarinda dan Tenggarong telah berlangsung untuk meningkatkan pengetahuan manajemen K3 di laboratorium. Program dilaksanakan dengan metode 25% teori; 75% praktek Manajemen K3, penilaian resiko, identifikasi bahaya dan penyusunan draft standard operational procedure (SOP) K3, Cardiopulmonary resuscitation (CPR), Pertolongan pertama pada kecelakaan (P3K) dan bahaya psikososial bertempat di FMIPA Universitas Mulawarman. Hasil yang diperoleh (berdasarkan angket evaluasi) adalah 97% peserta menyatakan peningkatan pengetahuan tentang manajemen K3, penilaian resiko serta identifikasi bahaya, SOP K3, CPR, P3K dan adanya bahaya psikososial di lingkungan laboratorium SMA.

Abstract

Multi-array Electrical Resistivity Tomography survey was conducted in coal mining concession of PT. Bukit Baiduri Energi at the Marandai pit, Loa Janan District, Kutai Kartanegara-East Kalimantan. Data acquisition has been done using the MAE-X612 unit with 48 electrodes and 5 meters interval and the maximum length of the survey was 235 meters. The aim of the survey is to analyze resistivity images from three different electrodes configurations for interpreting coal seams and other lithologies. We deployed three configurations, including Wenner-Schlumberger, Dipole-Dipole, and Pole-Dipole in one traverse. The resistivity images analyses were constrained using geological and geophysical logging.  The result shows that the Wenner-Schlumberger array is the reliable result comparing to the dipole-dipole and pole-dipole arrays. This technique will apply for further assessment to provide the reliable result in this coal mining concession. Electrical Resistivity Tomography offers rapid mapping for shallow mine working up to 45-meter depth. This method can be applied to one or two hour’s measurements with 48 electrodes with maximum 5-meter electrodes interval. This method offers the possible saving of drilling cost by using resistivity profile for coal seam correlation instead of conducting more drilling.
