JAKARTA - PT Hutama Karya (Persero) or HK is ready to operate one of the Trans Sumatra Toll Road (JTTS) sections, namely the 64.5 kilometer (km) Indralaya-Prabumulih Toll Road in the third quarter of 2023.

The toll road was built in mid-2019, this toll road construction has been completed 100 percent and has received an Operational LIKE Certificate (SLO) from the Directorate General of Highways, Ministry of Public Works and Public Housing (PUPR) last July.

Executive Vice President (EVP) of the Corporate Secretary of Hutama Karya, Tjahjo Purnomo said, with the issuance of the Decree of the Minister of Public Works and Public Housing Number 872/KPTS/M/2023 at the end of July, the Indralaya-Prabumulih Toll Road is ready to be operated in the near future.

Tjahjo said that previously this toll road had been specifically operational to support the flow of Eid Al-Fitr 2023 homecoming.

"The enthusiasm of the community is quite large, which is Hutama Karya's commitment to ensure the fulfillment of traffic management and safety standards for toll road users. This is supported by the doing of a series of Functional Feasibility Tests (ULF) which were also carried out last June," said Tjahjo in Jakarta, Thursday, August 10.

Overall, said Tjahjo, the toll road, which is designed at a speed of 100 km per hour, is equipped with 2 intersections, 18 bridges, and toll road support buildings, namely 2 rest areas.

It is estimated that if it passes through this toll road, it only takes approximately 1 hour from Palembang to Prabumulih, where if using arterial roads it will take up to 2 hours. This can then also shorten the travel time from Prabumulih to Mahmud Badaruddin II Airport in Palembang," he said.

Land Morphology In This Project Variations

The construction of the Indralaya-Prabumulih Toll Road was carried out by a subsidiary of Hutama Karya, PT Hutama Karya Infrastruktur (HKI) since mid-2019.

Work on the varied soil morphology of this project requires special handling, including the use of geofoam technology innovation on bridge oprit.

Geofoam is a light-weight beam material aimed at tackling unstable soil layers.

Functioning as a substitute for piles, Geofoam can minimize road subsidence which usually occurs at the pseudo point between the pile and the structure so that it can slow down subsidence or land subsidence during the toll road service period.

In addition to geofoam innovation, various soil morphology works also use the Treatment Prefabricated Vertical Drain (PVD) and Preloading.

PVD is a vertical drainage technology in the form of a plastic sheet that functions to accelerate soil water depletion.

In addition, Treatment Preloading is also carried out by providing a load on the ground before the construction of a structure that functions to reduce water levels in the ground.

These two treatments have the same function, namely to shorten the draining of water in the ground so that construction can begin immediately.

In terms of technology, HKI has also implemented comprehensive construction digitization such as BIM (Building Information Modeling), and SAP-based Enterprise Resources Planning (ERP).

These two things initiate effective construction processes, from the planning phase to real-time listable business processes.

To support construction materials on this toll road, another Hutama Karya subsidiary, PT Hakaaston (HKA) also provided support materials in the form of Hotmix (aspal), Precast, Ready Mix (beton), and Guard Rail materials. The material is produced in a house using concrete from PT Semen Indogreen Sentosa (PT SIS) and PT Bhirawa Steel which is also part of Hutama Karya Group.

All materials used in this work have been adjusted to the technical specifications required, to maintain quality as well as quality so that the final results of the Indralaya-Prabumulih Toll Road last long, and are safe to use.

In order to pursue the completion target, acceleration is carried out in the pursuit of progress.

In this case, with the involvement of local vendors of 35 percent and the rest are domestic national vendors.

In addition, in working on this project, a number of challenges began to limit access to supply goods and materials to work locations, uncertain weather conditions, as well as the existence of soil improvement have been passed by the company.

However, this can be resolved properly, so that the Indralaya-Prabumulih Toll Road can be completed on time and beneficial for the people in Sumatra.

Hingga saat ini, Hutama Karya telah membangun Jalan Tol Trans Sumatra (JTTS) sepanjang uhu1.021,5 km, termasuk dengan jalan tol dukungan konstruksi. Untuk ruas tol Konstruksi 411,5 km dan 610 km ruas tol Operasi.
