Abstract

Lumajang is one of district at Jawa Timur regency where located Lamongan volcanic area. Lamongan volcano is a young monogenetic volcano that was growth from a fault at the summit. Eruption at Lamongan volcano not only occurred at the main volcano, but also at parasite cone at Lamongan volcanic area with 37 cinder cones dan 27 maars. Cinder cones dan maars formed from contact of magma and water that cause freatomagmatic eruption with pyroclastic debris and material deposit’s flow. This research focused at mapping western Lamongan volcanic area based on magnetic anomalies to conducted vulcanic activities at subsurface. Based on magnetic anomalies data, there is an area at south, west, and north with high temperature subsurface rock around maars and cinder cones, that is indicated by negative magnetic anomaly. Keywords: Lamongan volcano, maar, cinder cone, magnetic anomalies.

Abstract

Jeruklegi landfill has leachate management system that still potential for leachate infiltration in subsurface. Leachate contamination may occur if landfill activity is continuous and have an impact to local society. Leachate contamination is an environmental pollution man-made minor disaster clasified. This research is an early prevention step by identifying disaster source. Identification is done by analyzing leachate distribution in subsurface using geoelectrical method with Wenner-Schlumberger array. The result of data acquisition is resistivity which is processed to apparent resistivity. Apparent resistivity was modelled by inversion method that shows leachate contamination near surface by resistivity not least at 1 ohm.m. Leachate contamination was not found over 20 meters based on the lack of resistivity difference. This was confirmed by chemical test of bore well water that match to hygiene and sanitation standards. Keywords: leachate, resistivity, geoelectric, Wenner-Schlumberger.
