Abstract

High Speed Rail (HSR) is currently regarded as one of the most significant tecnological breakthrought in passenger transportation. Compare to a convensional train, a high speed train will shorten time travel. This study aims to evaluate the viability of high speed rail project based on financial analysis. The parameter used to analyse the financial viability are NPV, BCR, IRR, PP and Break Even Traffic Volume. The analyses also includes sensitivity analysis with a variety of discount rate, annual income and investment cost value. The result of financial viability analysis shows that the project does not meet the financial requirements. It is indicated by negative NPV value, IRR value of 0,27 to 2,28 smaller than the discount rate and PP value much longer than the concession period which are of 50 years. The result of Break Even Traffic Volume shows that the range of total demand number to reach NPV=0 are between 11,27 millions to 11,58 millions. The Number  is very much greater than total passenger number of Argo Parahiyangan train in the year 2018 that is 4,38 millions/ year. Even though based on the financial viability analysis the High speed rail Jakarta-Bandung project is not be feasible. However, based on the economic and social benefits the project is crucial to solve traffic congestion, reduce the pollution rate, and save the time travel.Keywords :High-Speed Train, financial analysis, financial feasibility parameters

Abstract

Transportation is a very important aspect to stimulate the economy, a region cannot be totally independent in meeting its own regional needs, so that the area needs other regions as a support where one of the connecting infrastructure is a toll road. The Terbanggi Besar - Pematang Panggang Toll Road is one of the 8 Trans Sumatra toll road projects that have entered the construction phase in 2017 which are planned to be operated in 2021. The tariff analysis carried out is based on the Ability to Pay (ATP) and Willigness to Pay (WTP) approach. The average ATP value obtained is Rp 131,638.00 / 100 km and the average WTP value obtained is Rp. 40,989.00 / 100 km. Respondent's ATP value > WTP value indicates that the ability to pay respondents is greater than willingness to pay because users have relatively high income but the utility of these services is relatively low. While the determination of ideal rates is based on the average value of ATP and WTP. Based on calculations, the price of the Terbanggi Besar - Pematang Panggang toll roads tariff is Rp. 86,314.00 / 100 km.

Abstract

With the increase in population and increasing the number of private vehicle ownership, it will cause traffic problems due to the many movements of community mobility, one of which is at the intersection. Bandar Lampung is one of the developing cities that experience these problems. One of the intersections in Bandar Lampung to be reviewed is the unsignalized intersection with 4 arms on Jendral Suprapto-S. Parman road. The purpose of this study is to evaluate and compare the performance of the intersection of Jenderal Suprapto-S. Parman road. Then the results of the analysis using KAJI are capacity (C) 2735 pcu / hour, degree of saturation (DS) 1.12, delay deviation (D) 43.01 sec / pcu and queuing probability (QP%) 60% - 122% with level service C. Analysis with the VISSIM program is a delay of 3.35 seconds / pcu (North), 5.4 seconds / pcu (West), 68.29 seconds / pcu (South), 33.89 seconds / pcu (East), while for long queue 31.68 m (North), 23.98 m (East), 190.3 m (South) and 31.13 m (West) with service level B. While the results of the Queue Theory analysis a delay of 49 seconds / pcu ( North), 39.2 seconds / pcu (West), 72.8 seconds / pcu (South) 124 seconds / pcu (East), while the queue length is 50 m (North), 63 m (East), 40 m (South ) and 25 m (West).

Abstract

This thesis discusses the analysis of the Way Pengubuan bridge that connects the Gunung Sugih and Terbanggi Subing regions which are separated by rivers and have bridges that have not yet fulfilled the feasibility of being a bridge completely. So that the Government made the Way Pengubuan bridge construction project which aims to facilitate community mobilization so that the community's economy can increase. The location of this study was carried out on Way Pengubuan bridge, Gunung Sugih - Terbanggi Subing, Lampung Tengah Regency, Lampung Province. The data needed during this research are planning standards issued by SNI, literature published bridge planning standards, and general bridge data obtained from P.T. YODYA KARYA (Persero) as a project contractor. The method carried out in this study is to use the data obtained then analyze the structure of the bridge, analyze the structure of the structure under the bridge. From the results of the study it can be seen that the type of bridge used is prestressed concrete with a total span of 80 m, the span between abutments and 40m pillars, 7m bridge width, 2x3.5m track width, and 2m sidewalk width, Reinforcing bar on Pier and Abutment heads using  Main Reinforcing bar D19, Reinforcing bar on Pier & Abutment Body using Main Reinforcing bar D25-250, Reinforcement on Abutment Feet using Reinforcing bar D22-50 meanwhile on Pier Foot uses Main Reinforcing bar D25-125.

Abstract

 Provinsi Jawa Barat dikenal sebagai salah satu pusat perekonomian Indonesia dengan kekayaan utama di sektor pertanian dan perternakan. Salah satu daerah di Provinsi Jawa Barat penghasil terbesar dari sektor-sektor tersebut adalah Kabupaten Bandung yang dilintasi oleh jalur kereta api. Sistem transportasi KA di Kabupaten Bandung sudah menjelma sebagai sarana transportasi umum utama, baik untuk pengangkutan barang maupun penumpang. Dengan keunggulan dan potensi moda transportasi KA, terlebih lagi untuk mendukung upaya pemerintah mengoptimalkan perekonomian Kabupaten Bandung, maka pemerintah berencana membangun jalur KA ganda lintas Gedebage-Cicalengka. Untuk mepermudah transportasi dan menambah kapasitas lintas akan dibangun jalur ganda kereta api pada Gedebage - Cicalengka.Analisis yang dilakukan terkait rencana pembangunan kereta ini adalah analisis finansial dengan meninjau NPV (Net Present Value), BCR (Benefit Cost Ratio), dan IRR (Economic Internal Rate of Return) untuk mengetahui layak atau tidaknya kereta ini direalisasikan. Data yang digunakan merupakan data sekunder berupa tarif kereta Rancaekek – Cicalengka, data pengoperasian kereta Bandung-Cicalengka, tarif dry port pada stasiun Gedebage, volume arus petikemas Gedebage, dan data Inflasi Bank Indonesia tahun 2004 sampai 2018.Skenario yang paling menguntungkan terdapat pada skenario 4, 8, dan 12  dengan nilai BCR 2,13 , 1,86 , dan 1,22. Dan nilai NPV berturut-turut sebesar Rp 229.838.227.622, Rp 174.619.472.560, Rp 44.386.116.874. Dan nilai IRR nya dari skenario tertinggi berturut- turut adalah 11,65%, 11,77%, 12,26%.Kata kunci: Analisis Finansial, Kerta Api, TransportasiAnalisis Kelayakan Finansial Pada Proyek Pembangunan Kereta Api Jalur Ganda Antara Gedebage - Cicalengka

Abstract

This study aims to analyze the effectiveness of railway services in Lampung on the Tanjung Karang–Kotabumi route from the users’ perspective using a quantitative survey-based approach. The research focuses on Rajabasa (economy class) and Kuala Stabas (premium class) train services. Data were collected through Likert-scale questionnaires and secondary sources using an accidental simple random sampling technique. The variables include traveler characteristics, travel characteristics, and transportation system facilities. Data validity and reliability were tested before being analyzed using the Classification and Regression Tree (CART) method. The results indicate that service effectiveness is strongly influenced by the quality of interaction between staff and passengers as well as the condition of physical carriage facilities. Staff attributes emerge as the most dominant factor with the highest satisfaction scores, while management aspects remain the primary weakness. Differences in facility quality between premium and economy classes and accessibility issues in premium services were also identified. The CART model reveals that integrated operational and service quality is the key determinant, with staff attributes as the strongest predictor. The optimal model was obtained at a 1.5 threshold with high accuracy.
