The purpose of this paper is to construct indices on Indonesia’s economic infrastructure. The components of infrastructure include transportation, communications and electricity. In constructing the indices, the authors use the longest available data covering the period 1970-2015. The indices of each component of infrastructure are aggregated linearly with the weights calculated using principal component analysis (PCA). The infrastructure index for Indonesia has had a positive increasing trend since 1970, particularly supported by the increase in the infrastructure indices of electricity and telecommunication. Meanwhile, the infrastructure index of transportation has been relatively stable. The infrastructure index constructed shows positive relation with Indonesia’s GDP growth and GDP per capita.

The infrastructure index for Indonesia has a positive increasing trend since 1970, particularly supported by the increase in the infrastructure indices of electricity and telecommunication. Meanwhile, the infrastructure index of transportation has been relatively stable. The infrastructure index constructed shows positive relation with Indonesia’s GDP growth and GDP per capita.

The novelty of this research is a construction of the infrastructure index for Indonesia. The infrastructure index is important to benchmark the level of infrastructure development and to understand its connection to economic growth. It is also an important barometer used by policymakers for infrastructure investment and planning purposes.

This study aims to understand the factors and problems that relate to Indonesian port competitiveness and the problems that need to be addressed by major actors such as the government and port corporations.

It combines quantitative analysis from 59 survey respondents and qualitative analysis from focus-group discussions and in-depth interviews with port experts, financial bodies, port corporations and government officials on the condition of Indonesian port planning, development and financing.

An Indonesian port competitiveness model was developed, comprising government support, business support and operational performance. The authors found a gap between policy expectation and realization of port facilitation, caused by inefficient government bureaucracy, customs clearance and strategic decision-making. The government's consistency and commitment need work to encourage investor interest. Road connectivity, intermodal transportation, and energy infrastructure should be enhanced to increase operational performance. These problems are caused by a lack of feasibility analysis, consideration of local economic developments, and late adoption of standard technology. The maritime-sector workforce should be trained to be more professional with foreign players, more innovative and more open towards foreign assistance.

Port competitiveness includes government-related variables. The government’s initiatives are welcomed but are not enough. Adequate attention to both micro and macro port is necessary to increase port competitiveness. Future research should develop more comprehensive solutions to increase port competitiveness in Indonesia using problems and factors outlined here.

The study investigated the unique factors and problems that relate to Indonesian port competitiveness. It uses a national scope and rich expert data involved in Indonesia's port industry.

In responding to global issues of creating sustainable development, the Indonesian government has enacted regulations (i.e. Ministry of Public Works and Housing No. 05/PRT/M/2015) on the implementation of sustainable construction in infrastructure project execution. The purpose of this paper is to evaluate the means of implementing sustainable principles in the execution of infrastructure projects in Indonesia by the main construction service providers and their partners. A lesson-learned is presented as a source of knowledge to underpin the extensive implementation of sustainable principles in the construction of infrastructure projects leading to an integrated approach in creating a sustainable infrastructure that fulfills the requirements of sustainable development.

The method used is questionnaire surveys with Indonesian construction practitioners who are working on building construction, road and bridge construction, water facilities construction and house and settlement construction.

From the results, the practices of sustainability principles by construction service providers in infrastructure project execution are imperative from the project procurement phase. The evaluation continues to the phase of construction project execution, which reveals the inconsiderable performance of sustainability indicators due to current constraints on the implementation of sustainability principles.

This research looks into the existing gaps between sustainable construction principles and their practical implementation in Indonesian infrastructure projects. This will foster a holistic approach in the practice of undertaking sustainable procurement processes, thus reinforcing project management techniques in the phase of sustainable construction project execution. This also strengthens the interrelated roles and responsibilities of project stakeholders by taking into account principles of safety, balance and the harmony of infrastructure and the environment.

This chapter discusses the opportunity of Islamic project financing implementation for public infrastructure development in Indonesia.

This chapter, firstly, reviewed existing literature on Islamic finance to explore the applicability of Islamic financing in infrastructure development. Interviews were conducted as the first stage of Delphi method approach. This was then followed by reviewing Indonesia’s government policies and regulations in infrastructure industry and Islamic financing.

This chapter enlightens the implementation of Islamic financing on infrastructure project financing in Indonesia. The findings indicate that the government policies and regulations on both infrastructure investment and Islamic financing support the implementation of Islamic project financing, whereas, an improvement is still needed in order to overarch infrastructure business and Islamic financing investment.

Financing framework development for Indonesia infrastructure projects.

The result reported comprises the preliminary study of Islamic project paper written based on published research papers and interviews. Furthermore, the data collected for the study are limited to the case of Indonesian infrastructure projects.

Islamic financing in Indonesia infrastructure projects development has not been optimally implemented. Therefore, this chapter serves as a catalyst to explore alternative financial scheme such as Islamic financing for infrastructure development.

This chapter highlights possibilities and obstacles in applying Islamic scheme to infrastructure project financing. This provides a framework to analyse the steps to implement Islamic financing successfully in infrastructure development.

This paper delves into the ex ante rates of return demanded by the private sector in Indonesian public–private partnership (PPP) infrastructure projects and the manifold factors emanating from project attributes that can influence these rates.

This paper analyzes feasibility studies of 37 PPP projects across different sectors. The studies were carefully selected based on relevance, completeness and validity of data. The analysis uses statistical techniques, including Levene’s tests, t-tests, ANOVA tests, Cohen’s effect size and Pearson correlations, to explore differences in cost of capital and excess returns across various attributes.

Based on the statistical analysis, no significant difference exists between the excess return of 200 basis points (bps) and the equity excess return of 0 bps. This suggests that the eligibility criteria for PPP projects require an internal rate of return (IRR) equal to the weighted average cost of capital plus 200 bps or an equity IRR equal to the cost of equity. The variations in the tested variables among diverse project attributes do not exhibit statistically significant disparities, even though specific attributes display moderate to high effect sizes.

This paper represents one of the first attempts to examine the rates of return demanded by the private sector in the context of Indonesian PPP projects. It comprehensively explores the factors that influence these rates, drawing on insights derived from feasibility studies.

This paper aims to provide feasible business model options that benefit all stakeholders; the government, the investor and especially the inhabitants in Maluku and Papua, the less-favored business regions in Indonesia.

Three feasible business model options result from ICT for development literature, current role of the government, other models and investment scheme review, statistical analysis, technology analysis and investment simulations.

This paper proposes three different feasible business model options. The infrastructure subsidy model, which combines 20 per cent private investment and 80 per cent government subsidy, is the most feasible business model based on investment simulations. This model which combines 20 per cent private investment and 80 per cent government subsidy provides stronger determination of Indonesian Government for serving rural and remote people. The revenue subsidy and the mixed project subsidy are alternative models that may provide more attractive schemes from the standpoint of investors.

However, current paper has limitation which is subject to enhance for better analysis in future research such as implementation of the in-depth assessment of risk management system to deal with all exposed risks.

This paper provides that setting up a complete telecommunication access infrastructures in eastern Indonesia is feasible under new proposed models.

The new proposed models provide stronger determination of Indonesian Government for serving rural and remote people and minimizing the digital divide in eastern area.

Under the new proposed models, the role and capacity of the government is adjusted. The government should dominate and be less dependent on private investment. Also, the government should shift from triggering service penetration into developing a complete infrastructure set up.

Digitization of terrestrial television enables government to reallocate a portion of spectrum to satisfy the 5G low-band spectrum demand. To accelerate the digitization process, the Indonesian Government has distributed digital terrestrial television (DTT) decoders for households in several DTT trial areas so that the recipients are able to experience DTT broadcasts on their analogue television. To ensure that the DTT is adopted sustainably, this study aims to provide evidence-based policy recommendations by first understanding underlying factors of the intention to purchase a new DTT receiver, either a new DTT decoder or an integrated digital television (DTV).

This study uses 2018 survey data collected by Badan Aksesibilitas Telekomunikasi dan Informasi. The samples consist of 433 DTT decoder recipients in nine DTT trial locations in Indonesia. Two logistic models are used, one model for the DTT decoder and the other for integrated DTV. The two models have identical predictors, including respondents' demographics, television media use, technology cluster and DTT-related factors as innovation attributes.

The results indicate that the two models share some relevant variables but varying in sign and magnitude, namely, respondents' geographical location and the DTT picture and sound quality. The results also show that pay-television subscription, TV viewing and the difficulty of using the DTT decoder are other factors significantly associated with the intention to purchase a new DTT decoder.

This study has several limitations. First, the coefficients of determination are low, indicating that more independent variables should be included in the estimation models to obtain better insight about DTT adoption so that a better policy can be stipulated accordingly. Second, even though most of the predictors and proposed recommendations can be applied in general, all respondents of this study were DTT decoder recipients. Thus, future research can be more inclusive. Third, this study is designed based on the correlational model. This might cause the inability of the results to provide a conclusive direction of the relationship.

Demand-side and supply-side approaches are proposed to drive sustainable adoption of DTT, including the provision of subsidy or free DTT decoder for low-income households, increasing competition intensity among DTT devices manufacturers and distributors by allowing more players enter the Indonesian market, driving nationwide DTT infrastructure deployment and stipulating a national standard of the DTT devices.

This study enriches the understanding of the DTT adoption by incorporating geographical location variables for the proxy of infrastructure availability into the diffusion of innovation model, which has never been addressed by previous studies in the context of DTV adoption. In addition, this study focuses on a specific context in which all samples are free decoder recipients so that they have the same chance to experience DTT broadcasts.
