Slump is a movement of unlithified mass sediment gravity flow from particular bathymetry into deeper zone of the sea which caused by slope instability or earthquake. The slope instability is caused by rapid mass sediment distribution. Later, it would create a steep body of sediment mass then trigger the landslide. The sliding mechanism is producing some internal deformation such as folding and thrust fault on its anatomy. Slump also might indicate the paleomorfology or paleobasin and the direction of sediment transport. Located on the eastern side of the East Jiwo Hill – Bayat, Central Java, Temas Hill is an ideal spot for observing the slump and its mechanism. The exact outcrop position is on the east side of Temas Hill and it has never been observed before. Clastic limestone with shallow marine fossil content is dominated the whole research zone. These rocks types are presenting Oyo Formation which builds the Southern Mountain of East Java stratigraphy. Three methods are used for revealing the slump. Measuring section method is used to define the stratigraphic unit and its thickness. Structural data for interpreting the transport aim, then the Paleontological analysis to reveal the source of slump material. The output of this research reveals some new information. Stratigraphically, the slump consists of many units and contain lots of Foraminifera - Globigerinid, Paleonumulites, Cycloclypeus sp in mudstone - grainstone which indicate the source of the slump. Local NW – SE normal fault presumably triggering the huge mass of sediment to move and create the slump.

Pertambangan menghasilkan kerusakan lingkungan sangat dihindari dalam proses eksplorasi maupun eksploitasi sumber daya alam. Untuk itu diperlukan perlakuan khusus dengan berbagai pendekatan aspek geologi untuk meminimalisir kerusakan lingkungan setelah adanya proses penambangan. Salah satu tindakan tersebut yaitu dengan melakukan reklamasi lahan bekas tambang. Penulis mencoba mengobservasi dengan metode analisis prinsip aspek geologi seperti morfologi, litologi, geologi lingkungan dan kebencanaan. Dengan analisis tersebut nantinya akan dapat ditenrukan cara yang tepat, efektif dan efisien dalam proses reklamasi bekas lahan tambang Bahan Galian C.

Kata Kunci: reklamasi, geologi lingkungan, aspek geologi, kerusakan lingkungan.
