IMPROVING PASSENGERS SATISFACTION OF “TRAVEL” CORRIDOR PADANG-PESISIR SELATAN USING IMPORTANCE - SATISFACTION ANALYSIS (ISA)

This study was motivated by the case of the disappearance of legal bus services due to their loss in competition with a kind of car services called “Travel” for the corridor of Padang - Pesisir Selatan, West Sumatera, Indonesia. Travel might not legal public transport services, and therefore, in this study is also called un-official public transportation. This study aims to determine the driving attributes for passenger’s satisfaction of un-official public transportation services and to figure out the service attributes that need to be improved according to passengers’ perceptions. Data was collected using random sampling with a total sample of 160 respondents and was analyzed using the Importance Satisfaction Analysis (ISA) method. Quadrant analysis of ISA revealed that the availability of music and air conditioner on-board is not so essential but resulting a higher satisfaction to passengers. Passengers are calling for an improvement of the services by consistently implementing the law against a driver who uses a mobile phone while driving or driving inconsiderately, and improving the courtesy and friendliness of the driver

Study of the technical guidance application on the specific allocation fund (DAK) for road infrastructure (2017): Case study in the Public Works Office of West Sumatra

The specific allocation fund (DAK) is one of the central government programs used to provide the road infrastructure in regions of Indonesia. DAK 2017 used the technical guidelines for the implementation of the specific allocation fund in the infrastructure sector. The technical guidelines are a very important guideline in the implementation of DAK since the guidelines are composed according to the aim of ensuring the implementation or management of DAK for road infrastructure in accordance with the provisions, which should be orderly in their implementation and on target. A number of problems have been identified during the implementation: for instance, a low absorption of funds due to delays in the procurement process as well as changes in the organisational structure of DAK. Therefore, this research aimed to fill in the gaps in the issues in order to solve the problems encountered in the implementation of DAK for road infrastructure. This research was focused on the implementation of DAK in Payakumbuh, Bukittinggi, and Solok City, which are known as centres of economic growth in West Sumatra. They also support Padang city, the capital of the West Sumatra province. The study was mainly centred on the application of the technical guidance and any problems encountered. It was a qualitative research study and it applied the triangulation method as the validated approach. The results show that both Payakumbuh and Solok City have fulfilled the ten indicators of DAK implementation, on the other hand, Bukittinggi city can only fulfil nine indicators. In relation to the indicators of the handling program’s determination, the three other study sites did not apply what was instructed in the technical guideline in terms of conducting a survey to determine the road condition. In addition, these sites also did not send quarterly reports to the inspectors

Preliminary Study on Parking Control System for Proposed Transit Oriented Development (TOD) Area: Implementation Potential in Petaling Jaya City Council (MBPJ), Malaysia

Abstract: Rapid growth in the urbanised area presents many transportation and land use challenges for local and regional policy makers. As part of the key role in land use accessibility, parking management system is of significant importance to travelers making their travel decisions. It affects such diverse travel decisions as mode choice, trip destination choice and trip frequency. Transit Oriented Development (TOD) which offers a mix development of residential, retail, office and open space can respond to these challenges by supporting transit use. The combination of local pedestrian environment with access to CBD by transit would reduce the number of private vehicle dependency that will promote more environmentally friendly and sociable lifestyles. This study tries to look into the potential of parking control system in restricting the use of private vehicle within the proposed TOD area in Petaling Jaya City Council (MBPJ), Selangor, Malaysia

Rekomendasi Rencana Anggaran Biaya dari Audit Keselamatan Jalan Tahap Detail Engineering Design (DED) pada Jalan Nasional Provinsi Jambi

From 2016 – 2018 in Jambi province there were 3,543 traffic accidents, with 1,085 deaths. What causes traffic accidents is caused by three factors, human factors themselves, vehicle factors and road infrastructure factors. To reduce the occurrence of traffic accidents, you can eliminate or reduce the causes of traffic accidents, such as improving the safe condition of road infrastructure. The aim of this research is to calculate recommendations for budget plans from the results of road safety audits at the detailed engineering design (DED) stage, totaling six detailed engineering design (DED) documents on Jambi province national roads. This research uses road safety audit guidelines Pd 03 – 2019 – B. From the results of the analysis, the percentage between the safety cost recommendation results compared to the construction cost design (owner estimate) at DED 1 = 6.17%, DED 2 = 0.93%, DED 3 = 16.13%, DED 4 = 7.33%, DED 5 = 0.75% and DED 6 = 8.83% and the combined percentage obtained is 7.05%. Thus, a detailed engineering design (DED) still requires attention in producing a detailed engineering design (DED) that is oriented towards road safety and the costs of physical implementation of the results of road safety recommendations
