Abstract

ABSTRAK Adi Harianto, Program Studi Teknik Sipil, Program Pascasarjana, Institut Teknologi Nasional Malang, bulan Agustus tahun 2026, Judul Penerapan Value Engineering Untuk Optimasi Nilai Pekerjaan Trestle Pada Proyek Lamongan Oil Tank Terminal (LOTT) , Dosen Pembimbing (I) Ir. Maranatha W, ST, MMT, PhD, IPU, Dosen Pembimbing (II) Dr. Lila Ayu Ratna W, ST.,MT Pekerjaan trestle merupakan salah satu komponen utama Lamongan Oil Tank Terminal (LOTT) dengan nilai konstruksi yang signifikan, sehingga memiliki potensi untuk dioptimalkan melalui Value Engineering (VE). Penelitian ini bertujuan untuk menganalisis penerapan VE pada pekerjaan trestle dan menentukan alternatif yang memberikan nilai terbaik dengan tetap mempertahankan fungsi, kinerja teknis, mutu, serta keselamatan struktur. Penelitian ini menggunakan pendekatan Applied Engineering Research dengan tahapan VE Job Plan yang meliputi Information Phase, Function Analysis Phase, Creative Phase, Evaluation Phase, Development Phase, serta Presentation and Recommendation Phase. Data diperoleh dari Detail Engineering Design (DED), Rencana Anggaran Biaya (RAB), dokumen teknis proyek, observasi, dan penilaian lima ahli. Analisis meliputi Cost Breakdown Structure, Pareto, FAST, Cost-Worth Analysis, Analytical Hierarchy Process (AHP), Life Cycle Cost (LCC), verifikasi struktur, konstruktabilitas, dan risiko. Hasil analisis menunjukkan bahwa biaya desain eksisting dengan jarak pier head 8,7 m sebesar Rp. 219,249 miliar. Tahap kreatif menghasilkan alternatif bentang 16,2 m dan 21,2 m. AHP menunjukkan alternatif 16,2 m memiliki prioritas multikriteria tertinggi, sedangkan alternatif 21,2 m menghasilkan biaya konstruksi Rp. 162,230 miliar dengan potensi penghematan Rp. 57,019 miliar atau 26,01% serta LCC 50 tahun terendah sebesar Rp. 174,411 miliar. Verifikasi awal menunjukkan bahwa alternatif 21,2 m masih memenuhi batas defleksi, faktor keamanan, dan utilisasi yang digunakan dalam penelitian. Dengan demikian, alternatif bentang 21,2 m direkomendasikan sebagai usulan VE bersyarat, dengan persyaratan verifikasi struktur secara rinci, finalisasi kuantitas, rekonsiliasi LCC, persetujuan desain, QA/QC, dan mitigasi risiko sebelum implementasi.

Thesis entitled Penerapan Value Engineering Untuk Optimasi Nilai Pekerjaan Trestle Pada Proyek Lamongan Oil Tank Terminal (LOTT), Supervisor I: Ir. Maranatha W., S.T., M.M.T., PhD., IPU. Supervisor II: Dr. Lila Ayu Ratna W., S.T., M.T. The trestle is one of the major components of the Lamongan Oil Tank Terminal (LOTT), representing a substantial proportion of the construction cost and therefore offering significant potential for Value Engineering (VE). This study aims to analyse the application of VE to the trestle works and determine an alternative that provides the best value while maintaining the required functions, technical performance, quality, and structural safety. An Applied Engineering Research approach was adopted following the VE Job Plan, comprising the Information, Function Analysis, Creative, Evaluation, Development, and Presentation and Recommendation phases. Data were obtained from the Detail Engineering Design (DED), Bill of Quantities and cost estimates, project technical documents, observations, and assessments by five experts. The analysis incorporated Cost Breakdown Structure, Pareto analysis, FAST, Cost-Worth Analysis, Analytical Hierarchy Process (AHP), Life Cycle Cost (LCC), structural verification, constructability, and risk assessment. The existing design, with an 8.7 m pier-head spacing, has an initial construction cost of IDR 219.249 billion. The Creative Phase generated alternatives with pier-head spacings of 16.2 m and 21.2 m. AHP identified the 16.2 m alternative as having the highest multicriteria priority, whereas the 21.2 m alternative achieved the lowest construction cost of IDR 162.230 billion, representing a potential saving of IDR 57.019 billion or 26.01%, and the lowest 50-year LCC of IDR 174.411 billion. Preliminary structural verification indicated that the 21.2 m alternative remained within the deflection, safety-factor, and utilisation limits adopted in the study. Therefore, the 21.2 m alternative is recommended as a conditional VE proposal, subject to detailed structural verification, final quantity take-off, LCC reconciliation, design approval, QA/QC, and risk mitigation before implementation.
