Abstract

Research has been carried out to detect the presence and distribution of rocks containing metallic minerals. Almost every object used every day contains metal elements, so the presence of metal is very important to support every human activity. The presence of metal minerals in nature is generally quite a lot, but the types of metallic minerals vary. The geomagnetic method is a geophysical method that can detect subsurface rocks containing metallic minerals based on the difference in the magnetic field between the rock and the surrounding rock. Processing of geomagnetic data obtained in the field begins with daily correction and correction of the earth's main magnetic field (IGRF). The correction results obtained are anomaly of the earth's magnetic field which is distributed horizontally on the surface. The results of the analysis in the form of local magnetic field anomalies (∆H) are divided into 3 (three) regions, the first having a value between -236.5 nT to -8 nT (nano tesla) as an area that has a high local magnetic field anomaly value. Second, the value of -377.2 nT to -236.4 nT as an area that has a moderate anomaly value. Third, the low anomaly values ranged from -778.4 nT to -377.1 nT. Areas that have high local magnetic field anomaly values are interpreted as ultramafic rocks, which are source rocks of nickel lateric deposits rich in ferromagnesian minerals, distributed in the southeastern part of the study area.

Abstract

Plants as medicinal ingredients have potential as antimicrobials and antioxidants, with various molecules that can protect the human body from pathogens and cellular oxidation. This is closely related to the secondary metabolitescontained in these plants. Currently there are several bacteria that are resistant to antibiotics, therefore it is necessary to find an alternative to overcome this resistance by conducting research on medicinal plants. Sekilang (Embeliaborneensis) is a plant that is used by the Dayak tribe in Kalimantan as an ingredient for catching fish, repelling leeches and hair care and does not rule out having medicinal properties. So it is necessary to do research on these plants, especially the bark. The purpose of this study was to determine the antibacterial activity of sekilang bark extract against Propionibacterium acnes and Staphylococcus epidermidis bacteria. Extraction of the active substance was carried out by maceration with ethanol solvent and antibacterial activity test using the disc diffusion method.
