Indonesian government attempts to improve connectivity and to increase regional activities in Sumatera Island through the development of Trans Sumatera Toll Road (TSTR). However, despite its benefits to local economic development in Sumatera, the project shows low feasibility due to a low amount of investment. It can be attributed from the lack of planning in the initial phase to produce a comprehensive route that considers the various potentials of the regions. Thus, this research aims to investigate alternative route planning of Trans Sumatera Toll Road particularly in this paper for Central Sumatera by studying Gross Regional Domestic Product (GRDP), population and other significant factors. This research exposes cities and districts in Riau, West Sumatera, and Jambi which potentially contribute to the regional economy. Each selected towns and districts will be integrated with the intermodal system and connected to other functions to establish the Trans Sumatera Toll Road project in Central Sumatera. Compared to existing estimation of investment from public records, this alternative route has generated a competitive cost of investment which is estimated around 118,053,400,074,696 rupiahs. The research findings are expected to become the basis to improve other similar infrastructure toll road project development.

Bahasa Abstract

Pembangunan Perencanaan Rute Infrastruktur Jalan: Meningkatkan Kelayakan Proyek Jalan Tol. Pemerintah Indonesia berupaya untuk meningkatkan konektivitas dan meningkatkan kegiatan ekonomi regional di Pulau Sumatera melalui pengembangan Jalan Tol Trans Sumatera (JTTS). Namun demikian, proyek tersebut masih menunjukkan kelayakan rendah yang disebabkan minimnya kelayakan investasi. Hal ini disebabkan kurangnya perencanaan pada tahap awal proyek dalam menghasilkan rute komprehensif dengan mempertimbangkan berbagai potensi daerah. Dengan demikian, penelitian ini bertujuan untuk menghasilkan perencanaan rute alternatif Jalan Tol Trans Sumatera (JTTS) khususnya Sumatera bagian tengah. Hal ini dilakukan dengan mempelajari Produk Domestik Regional Bruto (PDRB), populasi dan faktor signifikan lainnya. Penelitian akan menghasilkan kota dan kabupaten di Riau, Sumatera Barat dan Jambi yang potensinya diintegrasikan dengan sistem intermodal dan terhubung dengan fungsi lain pada proyek JTTS bagian Sumatera Tengah. Dibandingkan dengan estimasi biaya yang tercatat dalam catatan publik, rute alternatif ini menghasilkan biaya yang kompetitif yang mencapai 118.053.400.074.696 rupiah. Luaran penelitian diharapkan dapat digunakan sebagai dasar untuk pengembangan proyek infrastruktur lain di Indonesia.
