Prioritizing regional development strategies of free trade zone (FTZ) using the analytical hierarchy process (AHP) approach: A case study of Batam, Bintan, and Karimun (BBK), Riau islands province, Indonesia Pages 899-908 Right click to download the paper Download PDF

Authors: Sri Wahyuni, Hermanto Siregar, Ernan Rustiadi, Andrea Emma Pravitasari

Keywords: Analytical hierarchy process, Free trade zone, Priority, Regional development

Abstract:
In Indonesia, creating growth centres, such as the Free Trade Zone (FTZ), is a strategy for regional development to stimulate economic expansion. The location of the FTZ of the Batam, Bintan, Karimun (BBK) area has been chosen strategically near Singapore and Malaysia. As a recognized national strategic area, the BBK area demonstrates substantial potential to augment the advancement of the national economy. This research employs the Analytic Hierarchy Process (AHP) to examine programs to prioritize strategies for advancing regional development. AHP has been demonstrated to facilitate the structuring of problems, identifying common opinions among respondents, and formulating solutions. The findings indicate that land preparation and permits are priority initiatives (0.122), followed by institutional reinforcement (0,111) and simplified requirements (0,071). As an archipelago, the enhancement of basic Infrastructure is also essential (0.052), mainly to improve connectivity. The next priority should be to improve the quality of human resources (0,051), fostering a favourable environment for investment. The outcomes of this investigation are expected to enrich the corpus of regional studies literature and provide valuable insights in assessing the efficacy of FTZ policies.

Development of efficient strategies to optimize production efficiency: Evidence from Pine chemical industry Pages 419-430 Right click to download the paper Download PDF

Abstract:
A pine tree, namely Pinus merkusii is an indigenous species from Indonesia which grows extensively in the Island of Java, Sumatera, and Sulawesi. This plant produces both timber and non-timber forest products (TFP and NTFP). Resin or oleum pine resin, as the main NTFP of Pinus merkusii, becomes the raw material for the gum rosin and turpentine oil industry. Globally, Indonesia is ranked 3rd as a producer of pine products after China and Brazil, in which Perhutani as a State Owned Forestry Enterprise plays a major role in this industry. On average, Perhutani manufactures 65,000 tons of gum rosin and 14,000 turpentine oil per year. Entire volume of both pine products is produced by nine factories with various maximum capacities. Therefore, this research aims to measure efficiency and/or inefficiency score of each factory using data envelopment analysis (DEA) method, which is then complemented by a single bootstrap technique with 2.000 iterations to eliminate bias scores. Cost of raw material, labour, energy, and general affairs are employed as input variables, while the output variables are total revenue and production volume. As result, 27.3% inefficiency (efficiency score = 72.7%) is generally found in all Perhutani’s pine chemical factories. To resolve this inefficiency issue, analytical hierarchy process (AHP) pairwise comparison questionnaire is distributed to 13 expert respondents to determine prioritized operational capability to focus on in optimizing efficiency of production performance. Dimensions of Cost, Quality, Flexibility, Innovation, and Sustainability are selected to construct the AHP questionnaires.
