The Connectivity Quality as Part of Network Quality For a Sparse Road Network Hitapriya Suprayitno
Jurnal Transportasi: Sistem, Material, dan Infrastruktur Vol 1, No 1 (2018): Special Issue
Publisher : Lembaga Penelitian dan Pengabdian kepada Masyarakat - Institut Teknologi Sepuluh Nopember

As a developing country, in terms of road network, Indonesia is dominated by sparse road network : the regency, the provincial and the national road network. Therefore, the network quality of the road network is capital to be formulated. This paper is designated to present the research result on formulating the connectivity quality as part of network quality. The network quality is formulated based on network performance to execute its function. The main functions are to connect different points of the region, to flow the traffic and to cover the area on a certain density. The connectivity quality must measure how well the nodes are connected each other. The quality must be measured against a desired condition. This principal is derived afterward into three measures, i.e. : the percentage of number of connected nodes, the percentage of the total road length and the ratio of total shortest path distance. Connectivity quality is calculated for each vehicle category. A special matrix method for transportation network analyses must be used to execute the whole calculation.

Understanding the Infrastructure & Facility Demand Behaviour is important. Sometimes, comparing two Demand Behaviour need to be done. A method to make Distribution Similarity test has been developed for Transportation Trip Length Distribution Similarity test. This test can be used for comparing Infrastructure & Facility Demand Behavior. There are still questions on whether the test must be made upon the Distribution of Real Value or upon the Distribution of Percentage Value. The research result indicates that Comparing Distribution Similarity must use Distribution Percentage Value. The similarity must be measured based on Accepted Goodness of Fit measured in χ2 Value, and Accepted Difference Value measured in Absolute Difference Value.

Airport Management needs data on Passenger Volume. Passenger Volume varies annually, monthly, weekly, daily, and hourly. A different aspect of Airport Management needs different data on Pasengger Volume Variation. Each airport has its Variation Characteristics. Kilimanjaro International Airport is a unique airport, as it is located close to a Mountain Kilimanjaro. Knowing it’s Passenger Volume Variation is important. Three Variations have been observed, the monthly, the weekly, and the hourly. The monthly variation shows that the high season happens from July to October. Based on three months of data, the weekly variation shows the inconsistency of the variation pattern. The weekly index of variation could not be developed. While the daily variation shows that high daily volume exists from Friday to Sunday.

Surabaya school bus is one of public facilitiesassetsand itsperformance should be evaluated periodically. Because the school bus is a public asset, it necessary to process the facility asset management to maintain operational performance optimally and efficiently. The number of students who use the school bus declines from year to year. Therefore, it’s necessary to study the current performance of school buses and the number of potential students who can use the Surabaya school bus. The method used to survey the number of students utilizing school buses and to conduct school bus performance research. School bus itinerary starts from Dukuh Menanggal Street down to Dharmahusada Indah Street and back to Dukuh Menanggal Street. There are 43 schools along the school buses route. Travel time observed was 1 hour and 10 minutes. The load factoraverage of the 1stschool bus in segment 1 (Dukuh Menanggal - RSI) is 78.67% while in segment 2 (RSI - SMKN 5) it reaches 96%. The load factoraverage of 2nd school bus for segment 1 reach 31.33% and for segment 2 reach only 8%.The total number of students from 11 schools was 12,391 students. However, the number of passengers/day was only 38 students from the operational of two school buses. This indicates that many students were still reluctant to use school buses, so that school bus performance improvements are needed to attract high school and junior high school students.

Good understanding of Demand Behavior is important for Infrastructure and Facility Planning. Therefore, Field Survey for Travel Behavior Characterisitcs on Commuter Train Passenger is very important. The data collected and processed must be correct data. Meanwhile errors could easily happen in data collection and tabulation. How is the method to identify the data error. Experiment indicates several following methods : using spread-sheet software is strongly suggested for easiness to develop the whole process, establish numerical data tabulation for data error identification easiness, etablish code for data back-tracked, develop field survey data table, develop data error possibilities tabel, develop a error logical tests, develop spreadsheet logical test function, do error identification calculation.

Public Works Infrastructure is vital for the life of a region. Therefore, it needs to be well operated. The knowledge or science of Operation Management is well developed, mainly for a Production Entreprises. The operation of infrastructure is different from those of the production enterprise. Therefore the Basic Principle of Operation Management for Public Works Infrastructure needs to be developed. Based on the system analysis principle, several findings have been produced. The infrastructure operation system consists of different system components. The infrastructure form, the infrastructure function, and the infrastructure operation characteristics, together, form the operation mechanism. The operation management manages the operation mechanism to achieve a certain level of operating performance measure. The infrastructure main function can be divided into to serve the user in the region or to produce something for the region. The function to serve can be of three basic forms: to flow something, to be used (in sense of to occupy at a certain time) by the users, or to be used for certain interactive activities. Regarding the variety of the nature of the infrastructure forms, functions, and operation characteristics, the infrastructure operation mechanism is also varied a lot in nature. Thus the operation management will be different for different types of infrastructures.

Performance Evaluation is routine work for IAM. Related to this, the Performance Indicator and Performance Factor need to be well understood. This paper present the result of a preliminary reflection on infrastructure performance, performance indicator and performance factor. Basic Quality of infrastructure is measure by its Performance to execute its Function. Performance Factor is something that can influence the Performance. Performance may consists of several components. Each Performance components indicate different qualities. Each performance components may have different importance level and different value. Factor may consists of several factors. Each factor has its own nature as supporting or resisting to performance. Each factor has its own strength of influence, its own easiness to be manipulated, and its value.

River infrastructures can be defined as facilities and structures that support all activities related to river. Many infrastructures that exist along river stream but few of them are listed and recognized as an important part in the river system. The condition of assets that support the river function should be considered since it determines the sustainability of water supply system for many areas. Starting from upstream, there were dam and reservoir that constructed to reserve the water. Moreover, the water can be distributed to the downstream area for many requirements, such as irrigation system, hydro power, industrial process, etc. In the other hand, dam and reservoir also functioned as flood control that protect the downstream area from flood and inundation. In alluvial river, there were erosions that occurs as river flow velocity could transported soft soil numerously. Hence, the river bank protections were built in order to protect the nearby river infrastructures. Therefore, the infrastructures recognition as preliminary assessment to the river asset management need to be done in order to maintain the river system.

A plan to move the Indonesian capital from Jakarta to Kalimantan island has been decided. Socialization of this program has been done by the government. A contest for the urban capital plan has been organized. But the Basic Systematic Reflection on Capital Relocation has never been developed among the academician. This development should be started by observing Capital Relocation Experiences. Six capital relocations have been observed. The research indicates that relocate the national capital to a new location is not something uncommon or inappropriate. The majority reasons for the capital relocation are the old capital is already too dense, to balancing the development, or certain military reason. In general, the success of relocation is having a more appropriate capital city with a desired and controlled density. While, the general failure of capital relocation is uncontrolled development, thus becoming a dense city.

Timor Leste is a very young country. Road network is still pretty the only blood vessel of the economy. Road network need to be well managed following the principle of Infrastructure Asset Management. Thus, the national road network still has to be evaluated against the primary network quality: the connectivity. Assessment indicated that all national center activities are connected by national road network. But, the connectivity cannot be said to be good enough for certains. Due to the mountainous and hilly area, the roads still need to be improved in term of road cross section and road geometry.
