The increasing growth trend of the global Muslim population implies an increase in the consumption of halal products. The importance of the halal market attracts much attention from many stakeholders, including academia/researchers. Many scholars have conducted studies on halal topics. However, these studies cover broad topics, such as ICT potential in the halal sector, the halal supply chain, Islamic Law, and other halal studies related to natural sciences. This study aims to study the research gap and future trends of halal food additive and ingredient research in business and economics using bibliometric analysis. The data were obtained from the Scopus database from 1999 to 2022. The authors analyzed the keyword “Halal Consumption and Production” by using the general keyword “Halal or Haram Additive and Ingredient”. The dataset was uploaded on VOSviewer and R language (Bibliometrix) software. This study found a deficit of studies on halal food additives and ingredients in business and economics. The co-occurrence network output demonstrated that future studies on halal food additives and ingredients should consider clusters that have lower density and central positions, such as production–consumption and the supply chain, healthy foods, and the logistics market and health effects. The Bibliometrix strategic diagram of the 2020–2022 thematic evolution demonstrates a research gap in three out of four quadrants (i.e., emerging or declining, basic, and motor themes). This study suggests potential research areas in the field of halal food additives and ingredients, such as ethical and sustainable sourcing, responsible consumption, consumer sovereignty, international trade, economic modeling, food security, green/sustainable supply chain, and halal regulation and product safety.

The progress of Greater Mekong Sub-region (GMS) is presumed to pose challenges and implications for Indonesia. This study has the aim to investigate the impact of the recent development of sub-regional cooperation and cross-border economic development within GMS on Indonesia’s industrial development. Using qualitative methods, this study analyzed some variables, i.e., the background of GMS cooperation, infrastructure and investment progress, and Indonesia’s related economic policies and development. Data and information were collected from many sources (i.e., statistical databases, articles, newspapers, websites, un- and published documents, etc.) and presented qualitatively. This study found that GMS economic cooperation and development have lessons learned and implications for the industrial development in Indonesia. The efficiency of the service sector within GMS was contributed by the successful implementation of policies on infrastructure development since the beginning of the 1990s. The flying geese behavior and industrial fragmentation within GMS were contributed by a different stage of industrial development, different comparative advantage, and improvement of the service sector. The implication of GMS cooperation for Indonesia is the importance of public policy stability, more attractive investment of high-end products in GMS than Indonesia, and potential diminishing of Indonesia’s export.

The Singapore-Johor-Riau Growth Triangle (Sijori-GT) was initiated by the government of Singapore, Malaysia, and Indonesia in 1989. It took the advantages of complementarities among the involved regions. The peripheral regions were expected to reap benefits and gain spillovers from the extended metropolitan region of Singapore.  In the age of 30 years of the growth triangle, many scholars found great progress and challenges of the subregional economic cooperation such as unbalanced development and allegedly weak commitment of the participating countries in Riau Islands. This research has the aim to investigate the tenable commitments of Singapore’s and Malaysia’s Foreign Direct Investment (FDI) in Riau Islands. Using statistical data from Indonesia’s Ministry of Investment from 1990 to 2020, this study compared FDI in Riau Islands by origin, and Singapore's and Malaysia's FDI by sector and subsector. The data was analyzed using the independent sample t-test for two-variable comparison and analysis of variance (post-hoc test) for multiple-variable comparison. Finally, this study found that: firstly, investment of Singapore was larger than that of Malaysia in Riau Islands; secondly, Singapore specialized its investment in manufacturing sector having better comparative advantage while Malaysia specialized its investment in non-manufacturing sector with potential assumed capabilities in halal-related sectors. The implication of this research is the importance of provision of competitive policies on industrial land estate prices to attract more investment in Riau Islands and to improve halal-related services to take advantage of domestic halal market and cross-border halal trade.
