Abstract
Pembangunan jalan tol berperan penting dalam mendukung mobilitas dan pertumbuhan ekonomi nasional. Proyek Jalan Tol Solo–D.I. Yogyakarta–NYIA Kulonprogo Seksi 1 Paket 1.2 bertujuan meningkatkan konektivitas dan akses ke Bandara Internasional Yogyakarta. Sehingga dalam pelaksanaan pembangunannya, metode Quantity Take-Off (QTO) dengan metode konvensional dinilai kurang efisien, hadirnya Building Information Modeling (BIM) ditawarkan sebagai solusi modern yang lebih akurat dan efisien. Selain itu, Glass Fiber Reinforced Polymer (GFRP) dikembangkan sebagai alternatif tulangan baja karena sifatnya yang ringan, kuat, dan tahan korosi. Penelitian ini membahas perbandingan efisiensi waktu dan biaya antara metode konvensional, Building Information Modeling (BIM), serta penggunaan material Glass Fiber Reinforced Polymer (GFRP) sebagai alternatif tulangan baja pada struktur Box Culvert dan Box Underpass. Hasil analisis struktur menunjukkan bahwa GFRP memenuhi standar SNI 2847:2019 dan ACI 440.11 dalam aspek kekuatan lentur, lendutan, dan lebar retak, dengan catatan mempertimbangkan perbedaan sifat mekaniknya dibanding baja. Penggunaan GFRP menghasilkan durasi pelaksanaan 575 hari, lebih cepat dari metode konvensional 597 hari, dengan biaya RAP sebesar Rp29.192.497.345,95 dibandingkan tulangan baja sebesar Rp47.148.387.170, sehingga memberikan efisiensi biaya ±38%. Selain itu, perbandingan volume pekerjaan antara metode konvensional dan BIM menunjukkan deviasi sebesar 0,63%, di mana BIM menghasilkan volume yang lebih akurat melalui pemodelan 3D. Penjadwalan menggunakan BIM mempercepat proyek menjadi 590 hari, lebih singkat 7 hari dibandingkan metode konvensional, dan menghasilkan RAP sebesar Rp2.055.118.395.657, lebih hemat dibandingkan RAP konvensional Rp2.055.337.441.131. Temuan ini menunjukkan bahwa BIM dan GFRP berpotensi meningkatkan efisiensi dalam pelaksanaan proyek infrastruktur.

Toll road development plays a crucial role in supporting national mobility and economic growth. The Solo–D.I. Yogyakarta–NYIA Kulonprogo Toll Road Project, Section 1 Package 1.2, aims to enhance connectivity and access to Yogyakarta International Airport. In its implementation, the conventional Quantity Take-Off (QTO) method is considered less efficient, and the introduction of Building Information Modeling (BIM) is offered as a more accurate and efficient modern solution. Additionally, Glass Fiber Reinforced Polymer (GFRP) has been developed as an alternative to steel reinforcement due to its lightweight, high strength, and corrosion resistance properties. This study discusses a comparison of time and cost efficiency between conventional methods, BIM, and the use of GFRP as an alternative to steel reinforcement in Box Culvert and Box Underpass structures. Structural analysis results show that GFRP meets the standards of SNI 2847:2019 and ACI 440.11 in terms of flexural strength, deflection, and crack width, provided that its different mechanical properties from steel are properly considered. The use of GFRP results in a project duration of 575 days, faster than the conventional method's 597 days, with a RAP cost of Rp29,192,497,345.95 compared to steel reinforcement at Rp47,148,387,170, achieving a cost efficiency of approximately 38%. Furthermore, the comparison of work volume between conventional and BIM methods shows a deviation of 0.63%, where BIM produces more accurate volumes through 3D modeling. BIM-based scheduling also shortens the project to 590 days, 7 days faster than the conventional method, and results in a RAP of Rp2,055,118,395,657, which is more economical compared to the conventional RAP of Rp2,055,337,441,131. These findings indicate that BIM and GFRP have the potential to significantly improve efficiency in infrastructure project implementation.
