Abstract

Abstract The movement of people to fulfill their needs must be well planned, so that traffic congestion can be avoided. The increasing population in Bandar Lampung has an impact on the number of movements as a whole, and one of them is in the school area on Jalan Cendana-Jalan Ir. H. Juanda. This study aims to determine the generation and attraction models of movement in the school area, on Jalan Cendana-Jalan Ir. H. Juanda, Bandar Lampung. This study shows that the factors that influence the trip generation and trip attraction in the study area are the number of classrooms, the number of teachers and staffs, and student daily allowances. In addition, the trip generation and trip attraction that occur are large enough to affect traffic, especially in the morning, which indicates high land use activities in the morning in the area. Keywords: school area; traffic congestion; trip generation; trip attraction. Abstrak Pergerakan manusia untuk memenuhi kebutuhannya harus direncanakan dengan baik, agar kemacetan lalu lintas dapat dihindari. Jumlah penduduk di Kota Bandar Lampung yang terus meningkat berdampak pada jumlah pergerakan secara keseluruhan, dan salah satunya pada kawasan pendidikan di Jalan Cendana-Jalan Ir. H. Juanda. Penelitian ini bertujuan untuk mengetahui model bangkitan dan tarikan pergerakan di kawasan pendidikan, di Jalan Cendana-Jalan Ir. H. Juanda, Bandar Lampung. Studi ini menunjukkan bahwa faktor-faktor yang memengaruhi bangkitan dan tarikan pergerakan di wilayah studi adalah jumlah ruang kelas, jumlah guru dan tenaga kependidikan, serta uang saku murid per hari. Selain itu, bangkitan dan tarikan pergerakan yang terjadi cukup besar untuk memengaruhi lalu lintas, terutama di pagi hari, yang menandakan tingginya aktivitas guna lahan pada pagi hari di kawasan tersebut. Kata-kata kunci: kawasan pendidikan; kemacetan lalu lintas; bangkitan pergerakan; tarikan pergerakan.

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

Jammed occurs due to the road infrastructure services level which is smaller than traffic movement needs that available. And the road which potentially to congest is ZA Pagar Alam street. So the government had made a solution to decrease the traffic jam by built an underpass on ZA Pagar Alam street. Furthermore, considering the need for underpass construction aims to reduce jam that occurs, so the writer bring out a research topic that is analyzing traffic flow after the underpass was built and comparing with the traffic flow before the underpass was built. The analysis of this road section performance using the 2014 Indonesian Road Capacity Guidelines method.It is known that the degree of saturation has decreased from 2013 by 1.00. It became 0.655 in 2016 and still dropped in 2019 to 0.63. But, from 2016 to 2019 the decrease was not significant. The speed in 2016 was 42.1 km / hour, and in 2019 was 41 km / hour. From the speed data, the results are not appropriate to RSNI T-14 2004 whereas the speed standard for urban roads should be 50-80 km / hour. So, it can be concluded from the comparison research of before and after the underpass was built, the construction of underpass on the section of ZA Pagar Alam street is not effective to decrease traffic jam.Keywords: Road Section, Degree of Saturation, Underpass

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

Jakarta and Bandung city with a distance about 150 km must be taken more than three hours by highway or railway due to the ever-increasing mobility with limited infrastructure capacity.  This study analyzes the economic and financial feasibility of the Jakarta – Bandung high speed rail project and calculates the NPV, BCR, IRR, PI, and PP. The government through the SOE and China International Railway consortium initiated the construction of a high speed rail from Halim to Tegalluar with a 142,3 km rail length and an average speed of 250 km/h, construction began in 2015 and is expected to be completed by 2020. The analysis is done with assumption of 75% occupancy rate, with discount rate of 2% and 3,46%, and feasibility of the project by doing comparison of feasibility method that is NPV ≥ 0, BCR > 1, IRR > r, PI > 1, and PP is faster than NPV positive. In the highest value feasibility analysis obtained with 75% occupancy rate and discount rate 2%. If only calculate the economic benefits obtained value of NPV = 3.279.703.704,18 ≥ 0, BCR = 1,00 > 1, IRR = 6,45% > r, PI = 0,65 < 1, PP = 33,76 > 29 year. If only calculate the financial benefits obtained value of NPV = 8.677.268.827,83 ≥ 0, BCR = 1,01 > 1, IRR = 5,50% > r, PI = 0,79 < 1, PP = 34,47 < 38 year. If calculate the economic and financial benefits obtained value of NPV = 1.543.396.683.112,40 ≥ 0, BCR = 1,56 > 1, IRR = 105,46% > r, PI and PP can not be calculated because the positive value of NPV in the first year (2020).
