Orchestrating Innovation Network: Case of Sustainable Transportation Technology

Dita Novizayanti, Eko Agus Prasetio

Pages 35-41

Currently, the transportation sectors are heading into the advancement of sustainable transportation technology to tackle the issue of unsustainable transportation system which leads to various drawbacks in the future. One of the innovation in sustainable transportation technology is the development of electric vehicle (EV). However, there are noticeable difference between sustainable transportation system and conventional transportation system that requires a massive and synchronous network of related stakeholders to keep innovating and catch up with the progression. On the other side, transportation sector is one of the sector with the massive development that has the consequences of high risk and uncertainty, which leads to the tendency of innovation avoidance. Therefore, the innovation network of EV needs to be nurtured to ensure its sustainability. From the previous study on various sectors, the innovation strategy focuses on two matters: innovation target and actor integration. The latter purpose is required to be conducted in an inclusive manner by engaging people from inside or outside the organization. In the case of innovation in sustainable transportation, the vertical approach plays a significant role in terms of fostering technological advancement. The main solution to reach this objective is through the well-established research ecosystem, which significantly supported by R&D investment by the government. The government takes the role of the innovation strategy implementer to establish a strong research network. Besides as the R&D funder and the hub between researcher and industry, the government also take a role to keep the dynamics of an ecosystem through interaction stimulation, while also engage the innovation results to be relevant with the social, technological, environmental, and economic problems. Moreover, the research center also takes an important role in the ecosystem, such as to engage reiteratively with the industry, become the open-innovation enabler, have the dedicated research agenda, become the multidisciplinary innovation enabler, collaborate with multi-stakeholders, has core research infrastructure, and become the innovation cultural hub. While the country’s industrialization demand keep rising, the research center could consistently become the intermediaries in conducting the research and build the relationship with other non-industry actor. This way, the high risk and uncertainty of innovation could be reduced.

Pages 29-34

The purpose of this paper is to evaluate the economic and industrial scale of the production of NiFe2O4 for vehicle batteries using the hydrothermal synthesis method. The method used is to calculate gross profit margin (GPM), payback period (PBP), cumulative net present value (CNPV), total investment cost (TIC), and profitability index (PI). NiFe2O4 nanoparticles were synthesized with the main raw materials being NiCl2·6H2O, FeCl3·6H2O, and NaOH (1:2:8). Calculation results from GPM and CNPV/TIC from the NiFe2O4 industry using the hydrothermal synthesis method show the payback period (PBP) in the third year. So that in the third year onwards it can be predicted that the industry will experience profits. It is expected that NiFe2O4 can be applied on an industrial scale for Li-ion battery anodes.

Pages 22-28

An optimum design for a vehicle structure is always desired because the structure can significantly affect the vehicle's performance. However, some complex iterations are usually involved in the designing process. The objective of the present study is to implement the Simple Structural Surfaces (SSS) method for analyzing electric bus body structure that can reduce complexity in the stage of conceptual design. The SSS method model the vehicle structure as several planar sheets and determine the forces in each sheet. Implementing the SSS method at the early stage of the vehicle's development can minimize the number of parameter changes needed during the late stage of development. The results showed that compared with the results obtained from FEM, the SSS method gave the maximum stress value on the chassis in good accordance. Yet, the downside of using this method is that determining the deflections in the structure becomes a little bit complicated. Successfully implementing this strategy can reduce the time and cost required to develop an effective vehicle structure.

Bali Province in Indonesia is one of the most attractive tourist destinations in the world. The number of tourists visiting this province keeps increasing year by year parallel with the increase of the population of local citizens. Such a phenomenon will certainly increase travel demand and put pressure on the current transport infrastructure. Hence, transport infrastructure development is essential to support the travel demand. This study explores the possibility of implementing a new public transport system in the South Bali District, a district with numerous tourist attractions and activity centres. Data collection on the current transport system and land use in the district were carried out to understand potential corridors for public transport. A stated preference survey was also conducted to discover the public transport mode preferred by the respondents, encompassing tourists and local citizens. This study then recommends the type of public transport mode to be implemented in the district based on i) space availability, ii) respondent preference, and iii) ability to accommodate demand based on calculation. The study concludes that Automated Rapid Transit (ART) is a mode that has the highest potential to be implemented in South Bali Districts.

Rest Area Development in Central Java (Case Study: Rest Area on Semarang–Solo Toll Road)

Pages 1-8

The construction of the road network is carried out to support the growth and acceleration of the economic process and the development of the tourism industry. It is also projected to improve the socio-economic conditions of the community. In the last few years, the Central Java Government has built toll roads to connect several cities in Central Java in one fast lane. However, it was not followed by the construction of supporting facilities such as rest area that serves a place to rest for motorists when they experience fatigue during long trips. The existence of the place is still limited, and it was not evenly distributed along the toll road, causing long queues at the entrance of some rest area when the volume of the vehicles is overflow. Based on these problems, the purpose of this research is to study and develop the requirement of rest area that can meet the needs of motorists traveling through the toll roads in Central Java. To achieve these objectives, this research used a qualitative descriptive method to describe and explain the problems in the field, and further analyze them to get a comprehensive result. The result of this research is presented in the form of published research reports and scientific articles. It is expected to provide benefits to the relevant scientific field, especially those related to architecture in developing rest areas that suit the needs of road users.
