ABSTRAK
Penelitian dilakukan di Kota Bogor dimana Pemerintah Kota menargetkan untuk menjadi kota yang ramah bagi pejalan kaki dan mempunyai daya tarik untuk wisatawan. Penelitian ini bertujuan untuk mengidentifikasi kualitas jalur pejalan kaki dan menganalisa kualitasnya terhadap fasilitas primer dan fasilitas sekunder pariwiata. Berdasarkan metode GWI untuk menilai kualitas jalur pejalan kaki memiliki empat indikator yatu: keamanan, keselamatan, kenyamanan, dan daya tarik. Kualitas jalur pejalan kaki di seputaran Istana Kepresidenan Bogor dan Kebun Raya Bogor memiliki kualitas yang sangat baik. Analisis spasial juga dipakai untuk menjelaskan alasan kualitas jalur pejalan kaki yang baik dan kurang baik secara site dan situation. Kualitas jalur pejalan kaki yang sudah baik dan adanya fasilitas primer berupa objek wisata juga fasilitas sekunder dapat menunjang kegiatan wisata berbasis berjalan kaki di Kota Bogor.

ABSTRACT
This research study was conducted in Bogor City, where the local government intends to shape Bogor into a pedestrian friendly city and thus attract more tourism. The aim of this paper is to identify the quality of pedestrian pavements and analyze whether this aspect supports development of a city walking tour around Bogor Botanical Garden and Bogor Presidential Palace. GWI rsquo s method is used to assess the quality of pedestrian pavements which encompasses four main variables which are safety, security, comfortability, and attractiveness of each segments. The results conclude that pedestrian pavements around the two aforementioned attractions are of very good quality. Spatial analysis is also used to explain the reasons for good and bad quality footpaths with site and situation used as the factors. As a result, the good quality pedestrian pathways connect some tourist attractions which can support a walking tour in Bogor City.

The shear key is an important part of a precast segmental concrete bridge. Aside from its function of contributing to the distribution of shear force from one concrete segment to another, it helps to join precast concrete segments to become a complete bridge structure and provide continuity of movement for vehicles and pedestrian traffic. This numerical study discusses the behavior of a full-scale shear key connection without epoxy joining two concrete blocks representing segmental precast concrete at which two external forces load the blocks. Ferro Casting Ductile (FCD) is used as the metal shear key material where the shear key consists of two parts, a male and a female shear key. Numerical simulation is conducted using the ANSYS academic package, with nonlinear analysis implemented accordingly. The appropriate constitutive materials in relation to the numerical program, both for concrete and FCD, are taken from the appropriate literature. Two criteria are employed in the study; failure of the concrete block and yielding of the shear key that follows the von Mises criterion. Shear key connection system capacity is evaluated by applying different magnitudes of horizontal force. The validation of two numerical simulation studies is conducted by two experimental programs that cover laboratory experimentation of full-scale shear keys connecting two concrete blocks. The numerical and experimental results produce an almost similar relation of shear stress at the male shear key and vertical displacements of the upper block relative to the lower concrete block. Finally, a contour of shear key shear stress as a function of the different magnitudes of equivalent prestressing and different quality of concrete compressive strength is proposed.
