Abstract

The research is located in Cihaur, Sukabumi, West Java, occupied by the Jampang Formation, located in the Sunda-Banda Arc. The magmatic activity and complex tectonic setting in the arc have the potential to cause mineralization, resulting in several types of ore deposits such as porphyry, epithermal and skarn. The objectives of this research are to identify alteration, mineralization, and ore deposit types in the research area. The research methodology includes exploration drilling, alteration mapping, and laboratory analysis using XRD, petrography, and mineragraphy methods. Alteration of the research area consists of argillic alteration (illite, kaolin, and smectite), propylitic alteration (chlorite, epidote, and calcite), marbellized (95% calcite), and skarnization (clinopyroxene, wollastonite, chlorite-skarn, and epidote-skarn). In the skarn there are indications of a prograde stage characterized by pyroxene and wollastonite minerals, and a retrograde stage characterized by epidote, calcite, and chlorite minerals. Mineralization of the research area consists of galena, sphalerite, pyrrhotite, pyrite, and chalcopyrite. The presence of pyroxene and wollastonite minerals, as well as galena and sphalerite indicate that the skarn formed in the intermediate to distal zone.

Abstract

Creating a village map is essential for regional development planning. However, it can be costly and time-consuming. The purpose of community service is to map the area around Mandalamekar Village, Cimenyan District, Bandung Regency, as one of the supporting documents for village planning based on disaster mitigation. The scope of this community service activity includes field data acquisition, such as creating flight paths and aerial photography using UAV vehicles, as well as data processing, including ortho mosaic, digitizing maps, and spatial analysis. The community service activity will produce an Aerial Photo Image Map and Land Use Map of Mandalamekar Village, both of which will be created at a scale of 1:5000. The output from the Community Service activity can be utilized for village development planning based on disaster mitigation. Furthermore, training on drone operation and processing has been conducted with the expectation that employees of Mandala Mekar Village can utilize drone technology. The feedback from the survey suggests that the Community Service activity is aligned with the users' requirements and has the potential to offer solutions for Mandala Mekar Village.
