"In Banten has not been implemented, it should be done, Tal should not be implemented," said Dodi Aryadi, President Director of PT Karya Inti Sukses Sejahtera (KISS) when met at his office on Friday ( 13/10/2017).
The same thing was delivered by the President Director of PT Prodigi Dimas Kusuma. According to him, the quality of asphalt made from recycled plastic is more durable because it is able to absorb water. Unlike the hotmik that will peel off if the water pooled.
"It must be much more durable, because it absorbs water, it is also a new test, it has not yet been ratified by national testing institute," said Dimas.
Another construction entrepreneur, Eko Susilo, who is President Director of PT Ligar Corp, said that plastic asphalt can cut production costs so as to save the government budget in building infrastructure projects in Indonesia.
"We are very ready (building with plastic asphalt) .The price is not yet known, but it is expected to reduce construction costs," said Eko Susilo, when met at his office in Serang City, Friday (13/10/2017).
Nationally, non-decomposition of waste until 2019 is expected to reach 9.52 million tons or 14 percent of total waste in Indonesia. Plastic waste is predicted enough to build a road along the 190 thousand kilometers, assuming the use of waste two to five tons per kilometer.
This is also done to support the government's plan to reduce plastic waste up to 70 percent by 2025.
The Research and Development Agency (Balitbang) of the Ministry of Public Works and People's Housing (PUPR) is now developing asphalt-based plastic to reduce the accumulation of plastic waste.
Balitbang also claimed to issue recommendations related to technical issues and the availability of plastic raw materials in September-October 2017.
The hardening of road infrastructure in the form of plastic asphalt has been tested in Udayana University, Bali, and Sri Ratu Mahendradatta Highway, on July 28-29, 2017, by cooperating with the Coordinating Ministry for the Ministry of Marine Affairs.
A 700-meter-long road trial was conducted to determine how high the resistance is, and how strong the plastic asphalt power is.
The funds needed to pave the 700-meter-long road is about Rp 600 million for a one-layer layer with a thickness of 4 centimeters. This cost in claims is much cheaper than ordinary aspla. Not only that, the level of stability is also 40 percent higher because roads with asphalt without plastic should be repeatedly coated to achieve adequate stability.
In addition to Bali, the government claims to be conducting a plastic-asphalting trial in the sphere of Istana Negara Jakarta.
Not only that, the trials are also conducted on the national road in Bekasi, namely, Jalan Raya Bekasi-Cikarang in mid-August 2017. With a 2 km long and 14 meters wide, the cost required to pave Rp 1.5 billion.
