The condition of the geological structure, land use, and slope in Trangkil Sukorejo Gunungpati Semarang City’s residential area can influence the occurrence of the landslide. In this study zoning is conducted to identifying the landslide vulnerable area and based on three main parameters that affect the occurrence of land movement, i.e., Geological Structure (A), Slope (B), and land use (C) according to weighted formula H (Weight) = ((0,24xA) + (0,38xB) + (0,38xC)). The result indicates that the southern part of the settlement is relatively safe than the northern part where the landslide vulnerability point is located, there is a fracture that can trigger the water entry through the weathered breccia.

Karakter adalah kebiasaan yang dilakukan secara berulang-ulang serta bisa mencirikan seseorang. Dalam prosesnya, pengenalan karakter bisa dikenali melalui beberapa hal salah satunya dari instrumen di wajah, karena wajah bisa mengekspresikan perasaan seseorang, salah satu instrumen wajah yang bisa dikenali yaitu dilihat dari bentuk bibir, karena bibir berhubungan dengan kemampuan komunikasi. Sehingga dalam penelitian ini dikhususkan pada pengenalan karakter bentuk bibir. Pengenalan karakter dari bentuk bibir disini menggunakan jaringan syaraf tiruan dengan metode Kohonen SOM. Adapun metode Kohonen SOM tidak dapat dilakukan secara langsung karena bentuk bibir diubah dari bentuk citra diekstraksi menggunakan PCA untuk bisa dilakukan proses pengolahan menggunakan Kohonen SOM. Dari hasil penelitian ini dilakukan Pada citra 20 mahasiswa, yang sesuai dengan bibir jenis ke-1 tidak ada, jenis ke-2 ada 3 mahasiswa, jenis ke-3 ada 7 mahasiswa, jenis ke-4 ada 3 mahasiswa, jenis ke-5 ada 2 mahasiswa, dan jenis ke-6 ada 5 mahasiswa

Morphologically the City of Semarang consists of Downtown and Uptown Semarang. Downtown Semarang which is composed of alluvial deposits and sandstone of the Damar Formation. Uptown Semarang composed of conglomerate of the Damar Formation, claystone of the Kalibiuk Formation, volcanic breccia of the Kaligetas Formation, volcanic breccia of Ungaran Volcano, Andesite igneous rock, and Basalt igneous rocks. Upper Semarang is hilly, some of which have steep slopes, especially on the Semarang Fault Zone. This condition makes the area frequent landslides. To find out the zone that is prone to landslides in the area around the Semarang Fault, slope stability analysis and microtremor measurements were performed. Slope stability analysis was carried out at 7 points using the bishop method based on slope, specific gravity, internal shear angle and soil cohesion. The acquisition by microtremor method was carried out at 9 trajectories that were estimated to pass through the Semarang Fault, then from the Horizontal to Vertival Spectral Ratio (HVSR) curves obtained was carried out an inversion to obtain the shear wave velocity profile on the trajectory. From the two methods of analysis found several locations with potential landslides, namely in the area of Mangun Harjo in the east of the study area, Karangrejo in the middle of the study area and Sadeng in the west of the study area.
