Abstract

As one of the most popular destinations in Indonesia, Bali has experienced growth in its domestic passenger arrivals over the last few years. Travel restrictions during COVID-19 have reduced airline passenger numbers on the Jakarta-Denpasar route. The travel restriction has loosened, and the economy is starting to recover in January 2022. However, the number of domestic passengers arriving in Denpasar has not returned to its former state. This research aims to understand the influential factors in the airline decision-making of domestic passengers on the Jakarta-Denpasar route. We started the research with an exploratory study to find the influential factors in which we obtained five attributes. The attributes include airfare, flight schedule, transit number, travel time, and HEPA filter. We conducted a stated choice experiment with five alternatives: Foreign private LCC, Private FSC, Private LCC, Flag LCC, and Flag FSC. The questionnaire was designed with a D-efficient design. We obtained 256 respondents, and there are 2048 observations for the Mixed Multinomial Logit Model estimation. From the estimation, we found that airfare, number of transits, travel time, and HEPA filter are all significant with expected signs. We also found that the flight schedule is not significant. Several socio-demographic variables, such as Gender, Age (except for Flag FSC), and income (also except for Flag FSC), are insignificant in airline choice decisions. We also presented the calculation of elasticity as well as the willingness to pay. Further, we propose that all airlines increase their direct flights for the Jakarta-Denpasar route since respondents prefer less transit. As people are more concerned about public transport’s hygiene, stating that HEPA filters’ availability in airline promotion is also recommended to gain more trust. Finally, our paper offers recommendations for airlines to improve their services and passenger satisfaction after the pandemic recovery period.

Abstract

Indonesia’s adoption of battery electric vehicles (BEVs) remains limited, posing a challenge to the government’s ambitious targets for 2030 and beyond. This study adopts a mixed-methods approach, combining qualitative insights from focus group discussions and stakeholder interviews with quantitative analysis using a mixed multinomial logit (MMNL) model. The stated preference survey includes 1,360 respondents across six provinces in Java, providing broader geographic coverage than most prior studies in Indonesia. The analysis covers both two-wheeler (2W) and four-wheeler (4W) BEVs, while also differentiating preferences by brand, an often-overlooked factor in the Indonesian context. The MMNL results confirm that charging time, range, operational cost, and price significantly influence BEV preferences, with variations across vehicle segments and brand types. Shared concerns from both supply- and demand-side perspectives include affordability, underdeveloped charging infrastructure, and limited product-market fit. However, divergent priorities are evident: industry stakeholders emphasize the need for technological upgrades, consistent policy signals, and improvements in upstream supply chains, while consumers prioritize convenience and final purchase or operating costs, showing less sensitivity to advanced technical specifications. This study contributes to the literature by offering an integrated demand–supply perspective on BEV adoption in an emerging economy, while also introducing brand differentiation and wider geographic sampling as key novelties. Policy recommendations include accelerating fast-charging infrastructure, standardizing batteries, localizing battery production, and implementing stronger disincentives for internal combustion engine (ICE) vehicles. The strategic enforcement of Presidential Instruction No. 7/2022 is also highlighted as a critical step to demonstrate government commitment. Together, these insights provide actionable guidance for accelerating a more inclusive and effective transition to electric mobility in Indonesia.
