"[Trans Sumatera dengan Pendekatan Value Engineering.Perencanaan proyek infrastruktur JTTS menghabiskan investasi sebesar Rp 340 Triliun. Investasi sebesar itu hanya membangun Jalan Tol konvensional yaitu kendaraan golongan 1 sampai 5, seharusnya besarnya investasi tersebut mendapat nilai tambah multi fungsi. Untuk mendapatkan nilai tambah, metode rekayasa nilai (value engineering) mengidentifikasi fungsi-fungsi, menciptakan gagasan kreatif dan inovatif. Pengembangan fungsi dasar dari JTTS sebagai fungsi transportasi golongan 1 sampai 5 diawali dengan pendekatan ranking PDRB dan jumlah penduduk, pengembangan wilayah Sumatera dengan location quotient, ditambah dengan fungsi pariwisata, telekomunikasi fiber optic, integrasi median tol dengan kereta api, integrasi jalur sepeda motor, integrasi dengan pelabuhan sungai, perkebunan karet, integrasi pipa migas serta service dan rest area. Dengan adanya penambahan fungsi tersebut dapat menambah manfaat proyek infrastruktur Jalan Tol Trans Sumatera.

Planning JTTS Infrastructure project require investment Rp 340 trilion. Investment of the Toll Road just build conventional vehicle classes 1 to 5, the

magnitude of the investment should have the value added multi function.. In order to reach a goal to have additional value, using value engineering to identify

functions, creating creative and innovative ideas. Developing basic functions of JTTS as transportation functions from level 1 up to 5 begins ranking GDP and

total inhabitant, then to the development Sumatera of the location quotient and coupled with additional value of tourism function, fiber-optic telecommunication, toll road median integration with train, motorcycle integration pathway, integration with dryport, rubber plantation, integration oil & gas pipeline, service and rest area. With addition of several functions, it is to have increase the benefits of JTTS Infrastructure project.;Planning JTTS Infrastructure project require investment Rp 340 trilion.

"Mendorong proses percepatan proyek strategis nasional, beberapa ruas proyek jalan tol Trans Sumatera menggunakan metode kontrak rancang bangun yang memadukan beberapa tahapan menjadi proses paralel yang diharapkan dapat mempersingkat waktu konstruksi. Namun pada pelaksanaannya, masih ditemukan fenomena keterlambatan proyek dari waktu yang telah disetujui pada kontrak awal yang dapat menyebabkan pembengkakan biaya serta hilangnya peluang untuk mengerjakan proyek lain. Oleh karena itu, diperlukan proses pengendalian yang baik sebagai salah satu fungsi dari kegiatan manajemen konstruksi untuk meminimalisasi segala penyimpangan yang dapat terjadi selama proses berlangsungnya proyek. Penelitian ini menggunakan pendekatan Project Management Body of Knowledge (PMBOK) 6th Edition. Studi literatur dilakukan untuk penyusunan variabel, lalu dilakukan validasi pakar, pilot survey, penyebaran kuesioner utama kepada responden, kemudian dievaluasi dengan analisa komparatif, deskriptif, uji validitas dan reliabilitas, korelasi, analisa faktor dan regresi linier. Diperoleh tiga faktor risiko yang paling signifikan yaitu: kurangnya pengendalian terhadap persiapan proyek termasuk pembebasan lahan, pengadaan material dan alat serta perizinan menyebabkan realisasi pekerjaan yang tidak sesuai ; kurangnya kejelasan dan kelengkapan dokumen pelaksanaan sehingga terdapat ketidaksesuaian dengan kondisi riil ; serta data perencanaan yang kurang akurat serta perubahan desain yang cukup sering ditengah pekerjaan. Dari persamaan regresi, terlihat faktor risiko berkorelasi dengan kinerja waktu dan faktor risiko menurunkan kinerja waktu.

Encouraging the process of accelerating national strategic projects, several sections of the Trans Sumatra toll road project use a design and build contract method that combines several stages into a parallel process which is expected to shorten construction time. However, in practice, there is still a phenomenon of project delays from the time agreed upon in the initial contract which can lead to cost overruns and lost opportunities to work on other projects. Therefore, a good control process is needed as a function of construction management activities to minimize any deviations that can occur during the project process. This study uses the Project Management Body of Knowledge (PMBOK) 6th Edition approach. Literature study was carried out for the preparation of variables, then expert validation, pilot survey, distribution of the main questionnaire to respondents were carried out, then evaluated by comparative, descriptive analysis, validity and reliability testing, correlation, factor analysis and linear regression. The three most significant risk factors were obtained, namely: lack of control over project preparation including land acquisition, procurement of materials and tools and permits leading to inappropriate work realization; lack of clarity and completeness of implementation documents so that there are discrepancies with real conditions; and less accurate planning data and frequent design changes in the middle of work. From the regression equation, it can be seen that risk factors correlate with time performance and risk factors decrease time performance."

"ABSTRAKProyek infrastruktur Jalan Tol Trans Sumatera (JTTS) direncanakan membentangdari Bakauheni-Banda Aceh dengan perkiraan investasi sebesar Rp290 Triliun.Studi rekayasa nilai tambah dilakukan pada proyek JTTS dengan menambahkanenam fungsi, yaitu integrasi jalur sepeda motor, pengembangan rest area, integrasidry port, integrasi kereta median tol, pengembangan area periwisata danpenambahan jaringan fiber optik. Penelitian bertujuan untuk mengetahui kelayakanfinansial dari rekayasa fungsi tambah proyek JTTS. Analisis kelayakan dilakukanmenggunakan pendekatan sistem dinamik terhadap tiga skenario tarif. Dari hasilpenelitian didapatkan hasil Internal Rate of Return untuk ketiga skenario tarif, yaitu8.28%, 12.71% dan 13.77%.

ABSTRACTInfrastructure project of Trans Sumatra Toll Road (JTTS) are planned stretch fromBakauheni to Banda Aceh with an estimated investment of IDR 290 Trillion. ValueEngineering studies have been done on the project JTTS by adding six additionalfunctions, that are integration of the motor bike paths, rest area development,integration of the dry port, rail way integration on median toll, development oftourism areas, and integration of fiber optic networks . The study aims to determinethe financial feasibility of the additional functions JTTS. The feasibility analysis isperformed using a dynamic systems approach to the three tariff scenarios. The studygot the results that Internal Rate of Return for the three tariff scenarios are 8.28%,12.71% and 13.77%.;"
