Abstract

The accident rate between people and train actually can be reduced to minimum as the traffic of railway is not as crowded as road. This thesis is using stated prefence technique. Stated preference approaches with option statement in the form of hypothesis to be assessed by the respondent. With using regression analysis, researcher can see the dominant factors of the causes of railway-related accidents especially in Sukamenanti railway which is in a hypothetical situation. To determine the dominant factors causing accidents at railway based on the results of a questionnaire to the related instations to be compared with data on the number of train accident from 2012-2017 that obtained from the related instations with using regression analysis with the help of the SPSS program. The analysis result is: (the number of accidents from 2012-2017 ) = -9,256 + 0,008.X12+ 0,009.X6 + 0,011.X10 + 0,015.X5 From regression analysis result, dominant factors of railway-related accidents causes are inadequate railways, limited carriages, the inadequate of doorstop availability, the damages in engine, the factor of carriages age (X12), rider physic’s exhaustion while riding their vehicle (X6), Infrastructure damage such as worn rails, spaten railing, shovel rails, chained rails, cracked rail connections, skidding on rails, weathered bearings, incompatible ballasts, loose fitting, and unlocked wesel (X10), machinist’s body condition (exhausted)/sleepy while on duty (X5). Therefore the signification is a=0,05 with regression analysis test.

Abstract

The movement of the flow of people, vehicles and goods results in a variety of interactions. Almost all interactions require travel and produce traffic flow movements. One of them is the shopping movement that has several alternative destinations including traditional markets, supermarkets, department stores, plazas, malls and so on. Currently department stores are the right alternative - for consumers because there are various human needs available. In Lampung Transmart Carrefour Mall provides a parking area on one basement floor with a car park capacity of approximately 150 vehicles and added parking capacity in the area around the mall for cars and motorbikes that cannot fully accommodate the vehicles of visitors who come to visit due to the attraction of the mall facilities. Data retrieval is done by means of questionnaire surveys on weekdays and weekends, namely surveys of visitor attraction coming from Lampung Transmart Carrefour Mall. The data processing method used the Statistical Package for the Social Sciences (PSPP) Program, and analysis using multiple regression analysis. Visitors who come on weekday with an average of 10,140 people, and on weekends the most 26,367 people per day. In this travel attraction, the fac - tors that influence are the Visitor Origin Factor (X1), the Vehicle Parking Location Factor (X4), and the Factors of Visiting the Mall (X5). These three factors have a correlation value of

Abstract

Train is one of the most preferred modes of transportation for the people of Lampung. One of the efforts made by PT KAI in improving service quality was to build a double railroad track for Tanjung Karang - Kertapati train. The purpose of this study is to find out the analysis of the invest - ment feasibility of the double track construction carried out by PT KAI. The data used is the price data for the construction of the railway line per kilometer and the income data of PT. KAI from passenger trains and babaranjang. The parameters used to review investment are using the Net Present Value (NPV) method, Benefit to Cost Ratio (BCR), Internal Rate of Return (IRR) and, Payback Period (PP). There are 8 (eight) scenarios in calculating the investment feasibility analysis in this study. Each scenario has a variation on the inflation rate and the occupancy rate (KTD) and the achievement of the volume of coal transport. The results of the investment feasibility analysis carried out, all scenarios are very profitable, but the most favorable scenario is scenario 8, with the source of investment funds coming from own funds, 100% KTD, 5% inflation rate, 25 million tons / year coal volume, and rate of return by 15%.

Abstract

Pangeran Antasari Street plays an important role in serving and passing large number of traf - fics. The traffics, coupled with roadside barriers, cause delays in travel time. The purpose of this study is to analyze the performance of roads that is the level of service as well as the increase in travel costs due to delays. The assessment of the performance of the road section was carried out based on free flow traffics, which is the condition of the traffic flow without experi - encing delays and roadside obstacles. Performance values were obtained through a linear approach between the volume and speed of the vehicle using the Greenshield Model. Calculation of Vehicle Operating Costs (Biaya Operasional Kendaraan or BOK) of light vehicles and heavy vehicles were using a model developed by the Indonesian Research Affiliation Institute of the Bandung Institute of Technology (Lembaga Afiliasi Penelitian Indonesia Institut Teknologi Bandung or LAPI - ITB). Whereas the motorcycle BOK were useing the Road Traffic Services (Di - nas Lalu Lintas Angkutan Jalan or DLLAJ) method. The value of travel time was calculated based on the approach using the data of the City of Bandar Lampung's per capita income di - vided by the average number of working hours per year. The results showed that the service level of the Pangeran Antasari road segment was V / C > 0.8. This means that the road has a service level of D, which is near congested. The cost of congestion caused by traffic delays for the direction of Pangeran Antasari - Gajah Mada is Rp. 625.863.840/year, while for the direc - tion of Gajah Mada - Antasari is Rp. 845.009.609/year.
