In Referring to the government programs on the increasing speed of the Jakarta-Surabaya express train in 2017, problems arise in the field, namely the potential increase in freight transportation via the railway line where an increase in loading is required on the railway especially for the existing bridge. This Research was implemented by increasing of the loading of the standard PM 60/2012 bridge to be compared with the EN1991: 2/2003 standard. This research analyzed the increase in structural strength of the 30m span steel bridge of the BH 182 constructed in Operational Region 2 Bandung as a results of loading adjustment from PM 60/2012 to EN 1991:2/2003.This paper explained an effect caused by increasing load on railway bridges with similar span and materials on normal plane, shear plane, moment and deflection. Structural analysis and calculation was performed by means of SAP2000 software. Results of analysis showed that standard equalization of EN 1991:2/2003 caused increasing percentage of loading combination of Comb L, normal plane, shear plane, moment plane, and deflection are of 35%, 60%, 71%, and 31%, respectively. While for Comb R loading combination for normal plane, shear plane, moment plane, and deflection are of 30%, 64%, 71%, and 30%, respectively.Keywords : PM 60 of 2012; EN1991:2-2003; SAP2000; Normal Field; Shear Field; Moment Field; Deflection.

In order to determine the actual condition of the railway bridge structure in the field, predictive monitoring is needed by installing a structural health monitoring system (SHMS). In the process of applying the SHMS, a bridge design review was applied to have railway bridge characteristics. The purpose of conducting this design review is to determine the allowable threshold for deflection and vibration of the bridge. This paper will present the analysis of the steel frame structure; with a span of 51.60 meters, 4.45 meters wide, of 5.00 meters high, respectively. According to the applicable standards, the loads used following the function of the bridge on the railroad tracks are calculated. The purpose of this paper is to (1) analyze the strength of the attached profile against the working forces, especially the live load of the rail line, (2) to know the deflection that occurs, (3) to know the natural frequency that occurs, and (4) to develop expert systems. The simulation results are used as the basis for placing sensors on the bridge and as the basis for determining the threshold for the railway bridge SHMS.

With the suboptimal performance of the Jakarta-Surabaya corridor railway currently operating, the Government of Indonesia intends to upgrade the railway system in terms of speed performance as well as to engage the participation of both the public and private sectors in the upgrading project as mandated in Presidential Regulation Number 38/2015. Through this research, the type selection of the Public-Private Partnership (PPP) scheme and their implications on the Jakarta-Surabaya railway project will be demonstrated by conducting analysis to the alternative scenarios of the study on railway technology selection with an emphasis on economic and financial feasibility aspects to determine the suitable PPP type, which is validated through Value for Money (VfM) analysis, where the benefits of the selected PPP type in terms of economic, financial, and non-financial aspects were examined through numerical tests, the result of which indicated that with the VfM value of the actual data of IDR 224.51 trillion, and the most significant changes in VfM value for each variable change are in the 20-year concession period which reduces the VfM value by 4%. Of all the variable changes, there is no minus VfM value, indicating that public projects are in an improved condition with the PPP scheme.

Desa Cisewu berada di Kabupaten Garut bagian selatan. Wilayah ini merupakan bentangalam perbukitan yang tersusun oleh material vulkanik berumur Kuarter. Struktur geologi  berupa kekar dan sesar di kawasan tersebut menambah risiko lahan bersifat labil. Oleh karena itu wajar jika kawasan tersebut rawan gerakan tanah. Populasi penduduk berkembang pesat mengingat wilayah ini strategis. Apalagi wilayah Cisewu merupakan penghubung, antara Jawa Barat bagian tengah dan selatan. Sebagian masyarakat Desa Cisewu telah berulang kali mengalami kerugian akibat bencana longsor. Relokasi warga hampir sulit dilakukan, mengingat budaya masyarakat setempat yang sulit meninggalkan tanah leluhur. Masyarakat Desa Cisewu perlu diberdayakan agar mampu berdikari serta tanggap terhadap darurat bencana gerakan tanah. Pemberdayaan masyarakat dapat dilakukan dengan cara memberikan berbagai pelatihan dan pendampingan dengan metode yang mudah dipahami. Pemahaman wilayah yang labil bisa disisipkan pada berbagai kegiatan dalam rangka pemberdayaan masyarakat. Sosialisasi beragam fenomena alam terkait kebencanaan perlu dilakukan dengan bahasa yang sederhana dan sesuai dengan tingkat pendidikan masyarakat setempat. Di sisi lain, masalah konservasi kawasan rawan bahaya alam juga perlu disosialisasikan. Target masyarakat dapat dikelompokkan berdasarkan usia dan latar belakang pendidikan. Pengembangan usaha berbasis potensi lokal perlu mendapat perhatian khusus. Potensi lokal ini perlu mendapat pendampingan untuk dapat bersaing dengan produk unggulan di daerah lainnya.
