Abstract

Purpose

The Indonesian Islamic banking industry is very promising, but there has been no analysis of the optimal and decreasing growth rate of the industry. Information regarding these is essential for policy makers, Islamic bankers and all related parties to guide the future development of the industry and sets up proper plans and strategies. The paper aims to explore the optimal and decreasing growth rates of the industry and in so doing contribute to the current literature on the Indonesian Islamic banking industry.

Design/methodology/approach

The paper first reports on the performance of the Indonesian Islamic banking industry, before explaining conditions where the Islamic banking industry is believed to be still immature. Third, in order to identify the optimal and decreasing growth rates, the paper estimates the future performance of the industry by using ARIMA models to identify periods where the growth rate is at optimal and decreasing points. Then, on the basis of a number of assumptions and statistical simulations, the analysis broadens to become qualitative in nature by determining the optimal numbers of Islamic banks to be established in the future.

Findings

The paper generates some important findings. First, the optimum growth rate of the market share (0.12 percent) is predicted to occur in December 2012; the market share in that month is estimated to be 5.75 percent. Second, although the market share keeps growing, the paper finds the rate of increase to be slow, and in October 2018, it becomes negative, at 0.004 percent. The estimated market share in that time is 11.63 percent. Finally, the optimal number of Islamic banks in December 2012 is shown to be 23 and in October 2018, 24.

Research limitations/implications

Qualitative information on the months of the optimal and decreasing growth rates and quantitative information on the optimal number of Islamic banks to be established are significant information for policy makers, Islamic bankers and other related parties. The information is likely to be important in relation to their efforts to develop the Islamic banking industry, to anticipate decreasing growth in the industry and to establish new Islamic banks. More generally, the paper helps the related parties to direct and guide the future development of the industry.

Originality/value

To the best of the authors' knowledge, this is the first paper that attempts to establish optimal and decreasing growth rates in the Indonesian Islamic banking industry, or the optimal numbers of Islamic banks to be established in the future.

Abstract

Purpose

This paper aims to investigate the current state of biocomposites used in fused deposition modelling (FDM) with a focus on their mechanical characteristics.

Design/methodology/approach

The study presents a variety of biocomposite materials that have been used in filaments for 3D printing by different researchers. The process of making filaments is then described, followed by a discussion of the process parameters associated with the FDM.

Findings

To achieve better mechanical properties of 3D-printed parts, it is essential to optimize the process parameters of FDM while considering the characteristics of the biocomposite material. Polylactic acid is considered the most promising matrix material due to its biodegradability and lower cost. Moreover, the use of natural fibres like hemp, flax and sugarcane bagasse as reinforcement to the polymer in FDM filaments improves the mechanical performance of printed parts.

Originality/value

The paper discusses the influence of critical process parameters of FDM like raster angle, layer thickness, infill density, infill pattern and extruder temperature on the mechanical properties of 3D-printed biocomposite.

Abstract

Purpose

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).

Design/methodology/approach

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.

Findings

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.

Research limitations/implications

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.

Practical implications

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.

Originality/value

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.
