Abstract

Penelitian ini bertujuan untuk memetakan pola dan alokasi penelitian mengenai kelayakan finansial proyek infrastruktur di Indonesia periode 2021–2025. Metode yang digunakan adalah Systematic Literature Review (SLR) dengan kerangka PRISMA. Pencarian literatur dilakukan melalui Google Scholar dan menghasilkan 16 jurnal yang memenuhi kriteria inklusi dari 153 dokumen awal. Data diekstraksi berdasarkan tujuan penelitian, indikator kelayakan finansial, jenis infrastruktur, cakupan geografis, dan status indeks Sinta. Hasil menunjukkan bahwa sektor transportasi darat, khususnya jalan dan jalan tol, mendominasi 50% studi yang dianalisis, dengan NPV sebagai indikator utama yang digunakan pada seluruh studi, diikuti oleh IRR, Payback Period, dan BCR. Distribusi geografis menunjukkan konsentrasi penelitian di Jawa dan Bali, sedangkan wilayah Indonesia timur masih sangat terbatas. Temuan ini menunjukkan adanya bias sektoral dan geografis dalam penelitian kelayakan finansial infrastruktur. Implikasi penelitian menegaskan perlunya diversifikasi sektor infrastruktur yang dikaji, peningkatan representasi wilayah luar Jawa, serta pendalaman metodologis melalui penerapan Value for Money, analisis risiko kuantitatif, dan skenario ketidakpastian. Dengan demikian, penelitian ini menyediakan pemetaan komprehensif yang dapat menjadi dasar pengembangan kebijakan dan penelitian lanjutan di bidang kelayakan finansial infrastruktur di Indonesia.

Abstract

This study aims to analyze the effect of bed slope variation on flow characteristics in an open channel flume at the Civil Engineering Laboratory of Universitas Lancang Kuning. The research was conducted experimentally using a laboratory flume with constant discharge conditions. Three slope variations were applied, namely 0.001, 0.003, and 0.005. The observed parameters include flow velocity and flow depth. In addition, the Froude number was calculated to determine the type of flow regime. The results indicate that increasing the bed slope leads to an increase in flow velocity from 0.20 m/s to 0.33 m/s. Meanwhile, the flow depth tends to decrease as the slope increases. The calculated Froude number ranges from 0.201 to 0.343, indicating that the flow regime remains in subcritical conditions. These results provide empirical insight into the relationship between bed slope and hydraulic characteristics in open channel flow and can serve as reference data for hydraulic laboratory experiments.

Abstract

Urban intersections are increasingly congested as motorized vehicle volumes continue to rise, while fixed-time signal control often fails to respond to dynamic traffic conditions. This review examines the use of Type-2 Fuzzy Logic (FL-T2) for adaptive signal timing control under traffic uncertainty and its relevance to Indonesian urban intersections. A systematic literature review was conducted on recent studies published between 2021 and 2025. The reviewed studies show that FL-T2 is generally built on fuzzification, rule-base formulation, inference, and defuzzification, with uncertainty represented through the Footprint of Uncertainty. The synthesis indicates that FL-T2 performs better than fixed-time control and Type-1 fuzzy logic in reducing delay, queue length, and saturation level, especially under fluctuating traffic conditions. Hybrid FL-T2 models with optimization algorithms also show stronger performance in simulation studies. However, practical implementation in Indonesia still depends on detector availability, data quality, computational feasibility, and institutional readiness. FL-T2 is therefore a promising adaptive control framework, but further local simulation and pilot testing are needed before field deployment.

Abstract

The subgrade in Paloh 80, Tanjung Rejo Village, Percut Sei Tuan District, Deli Serdang Regency, is a fine-grained clay with low stability, making it unsuitable for use as a road subgrade without stabilization. Therefore, stabilization efforts are needed to improve its technical properties. This study aims to analyze the effect of adding palm shell ash (ACS) on changes in the permeability coefficient of clay soil. The research method used is a laboratory experiment with variations in ACS mixtures at 0%, 4%, 6%, 8%, 10%, and 12% of the soil's dry weight under optimum water-content conditions. The stabilization process involves mixing clay soil with palm shell ash in varying proportions, followed by testing in accordance with ASTM standards, specifically the falling-head permeability test. The results show that adding palm shell ash significantly reduces the permeability coefficient of clay soil. The original soil permeability value of 8.339 × 10^(-8) cm/s decreased to 4.355 × 10^(-8) cm/s in the 12% mixture. This decrease was caused by the palm shell ash filler, which filled soil pore spaces, thereby inhibiting water flow. The results showed that the addition of ACS significantly reduced the permeability coefficient of clay soil. The original soil permeability value of 8.339 × 10^(-8) cm/s decreased to 4.355 × 10^(-9) cm/s in the 12% mixture. This decrease was caused by the ACS filler, which filled soil pore spaces, thereby inhibiting water flow. Thus, palm shell ash has potential as an environmentally friendly stabilization material to improve the quality of road subgrades.

Abstract

Pada sistem pelat gantung (suspended slab) dengan metal deck komposit, balok penumpu harus memenuhi panjang tumpuan (bearing length) minimum agar deck tidak bergeser saat pengecoran. Pengamatan lapangan pada Proyek Pabrik Central Plant 3 (CP3) PT Pesta Pora Abadi di Majalengka menemukan panjang tumpuan metal deck aktual hanya 25 mm—mengikuti tebal selimut beton (d = 25 mm)—atau 50% di bawah ketentuan minimum pabrikan sebesar 50 mm. Untuk mengatasinya tanpa membongkar struktur, dipasang profil baja siku (angle bar) L 50×50×5 yang dilas pada sengkang balok (tulangan polos BJTP 280) menggunakan elektroda AWS E70XX. Penelitian ini bertujuan memverifikasi kapasitas lentur profil siku dan sambungan lasnya pada tahap konstruksi dan tahap operasional berdasarkan SNI 1727:2020, SNI 1729:2020, dan SNI 1726:2019. Analisis dilakukan pada dua sampel pelat, yaitu sampel Center (tebal 150 mm, beban hidup 4,905 kN/m²) dan sampel Side (tebal 200 mm, beban hidup 19,62 kN/m² dari beban mesin), yang masing-masing ditinjau pada tahap konstruksi dan operasional serta dimodelkan dengan Tekla Structures. Hasil analisis menunjukkan pemasangan profil siku meningkatkan panjang tumpuan efektif menjadi 50 mm sehingga memenuhi persyaratan minimum. Rasio kapasitas lentur maksimum 0,88 dan rasio kapasitas geser las 0,40 keduanya terjadi pada sampel Side tahap operasional dan masih memenuhi kriteria aman (rasio < 1,0). Disimpulkan bahwa profil siku berperan sebagai pemikul beban utama pada tahap konstruksi dan sebagai elemen penstabil tepi yang tertanam pada tahap operasional saat pelat komposit telah bekerja sebagai sistem struktur utama.

Abstract

Pemanfaatan limbah Palm Oil Fuel Ash (POFA) sebagai material substitusi pada mortar busa menjadi alternatif dalam pengembangan material konstruksi ringan berbasis limbah agroindustri. Penelitian ini bertujuan menganalisis pengaruh variasi kadar dan ukuran butiran POFA terhadap kuat tekan serta berat isi mortar busa. Penelitian menggunakan desain kuantitatif eksperimental laboratorium. Material penyusun terdiri atas semen PCC, pasir Sungai Kampar, air sumur bor Kampus I Universitas Abdurrab, agen foam nabati SMACON, dan POFA sebagai material substitusi. Variasi kadar POFA adalah 0%, 10%, 20%, dan 30%, sedangkan fraksi ukuran nominal yang dibandingkan adalah 1,18 mm (saringan No. 16) dan 0,60 mm (saringan No. 30). Pengujian dilakukan pada umur 7 dan 14 hari sehingga hasil penelitian merepresentasikan performa umur awal mortar busa. Data dianalisis secara deskriptif-komparatif melalui perbandingan nilai rata-rata, perubahan terhadap campuran kontrol, serta rasio kuat tekan terhadap berat isi. Hasil menunjukkan bahwa pada umur 7 hari, kuat tekan tertinggi diperoleh pada campuran 30% POFA ukuran 0,60 mm (No. 30), sedangkan pada umur 14 hari kuat tekan tertinggi diperoleh pada campuran kontrol tanpa POFA. Berat isi terendah diperoleh pada campuran 20% POFA ukuran 1,18 mm (No. 16) umur 7 hari. Temuan ini menunjukkan bahwa penggunaan POFA berkaitan dengan perubahan kuat tekan dan berat isi mortar busa, tetapi pola perubahannya tidak linier. Secara praktis, POFA berpotensi dimanfaatkan sebagai material substitusi mortar busa, namun penerapannya memerlukan optimasi kadar, ukuran butiran, dan umur rencana agar diperoleh keseimbangan antara kekuatan mekanis dan karakter ringan material.

Abstract

This study evaluated the capacity of the drainage system along Rela–Sutomo Road, Medan, to accommodate rainfall runoff and domestic wastewater. Rapid urban development and population growth have increased impervious surface coverage, surface runoff, and domestic wastewater generation, potentially exceeding the conveyance capacity of the existing drainage channels. This study aimed to determine whether the existing drainage system could accommodate the combined design discharge. The analysis included population projection using the least-squares method, estimation of domestic wastewater discharge, rainfall frequency analysis using the selected probability distribution for a 10-year return period, rainfall intensity estimation using the Mononobe method, runoff calculation using the rational method, and channel capacity calculation using Manning’s formula. Sediment depths and channel dimensions were directly measured across 10 drainage segments. The results showed that the design runoff discharge for the selected 10-year return period reached 24.46 m³/s, whereas the existing channel capacity was only 1.31 m³/s. Sediment accumulation reduced the effective cross-sectional area and decreased the channel capacity by up to 30%. Consequently, the combined inflow substantially exceeded the available channel capacity, indicating critical hydraulic overload and a high risk of flooding and surface inundation. The existing drainage system is therefore inadequate and requires channel normalization, periodic sediment removal, and hydraulic capacity improvement

Abstract

Material tanah timbun merupakan komponen kritis dalam pekerjaan tanah infrastruktur pesisir, namun pemilihan material di Kota Dumai, Riau masih sering dilakukan berdasarkan jarak hauling dan biaya tanpa evaluasi kualitas teknis yang terukur. Penelitian ini mengevaluasi kelayakan geoteknik material dari tiga quarry lokal aktif—Pelintung, Bukit Nenas, dan Bukit Timah—untuk digunakan sebagai material timbunan dalam konstruksi sipil. Sampel terganggu diambil pada kedalaman 0,5–1,0 m dan diuji di laboratorium sesuai Standar Nasional Indonesia (SNI) meliputi kadar air alami, berat jenis, void ratio, porositas, batas Atterberg, dan uji pemadatan Proctor standar. Hasil dibandingkan dengan SNI 8460:2017 dan Spesifikasi Umum Bina Marga 2018 Divisi 3. Kadar air alami berkisar 10,43–16,12%, kepadatan kering maksimum 1,65–1,86 g/cm³, dan indeks plastisitas 9,60–13,68%. Material Quarry Pelintung memenuhi seluruh persyaratan dan diklasifikasikan sebagai timbunan pilihan (selected fill); Quarry Bukit Nenas layak sebagai timbunan umum (common fill) dengan pengendalian kadar air; sedangkan Quarry Bukit Timah bersifat marginal dan memerlukan pencampuran pasir atau pengeringan sebelum pemadatan. Tren invers antara indeks plastisitas dan kepadatan kering maksimum dikonfirmasi secara statistik. Temuan menunjukkan bahwa material quarry lokal Riau dapat dimanfaatkan secara optimal untuk konstruksi berkelanjutan apabila disesuaikan dengan fungsi struktural dan didukung pengendalian kadar air serta kepadatan lapangan yang disiplin.

Abstract

Pre-construction cost control in hospital ward completion projects requires a systematic approach capable of identifying cost concentration before construction begins because healthcare rehabilitation works involve complex interations among MEP-HVAC, sanitation, air-conditioning systems and functional building components. This study aims to develop a novel pre-construction cost control framework by integrating the Work Breakdown Structure (WBS), Pareto-ABC analysis, Area Cost Index (ACI) and a newly proposed Control Priority Index (CPI) for the A-KRIS Hospital Building completion project at RSUD Hj. Anna Lasmanah Banjarnegara. A quantitative descriptive case study was conducted through Bill of Quantity (BoQ) validation, WBS mapping, cost aggregation by work zone and sub-work, area cost index calculation, Pareto-ABC classification, and CPI formulation. The project cost was IDR 930,571,644 (including 11% VAT), with an area cost index of IDR 606,093/m2. Cost distribution was highly concentrated in Teratai Ward (60.18%) and Soka Ward (39.10%) accounted for 78.78% of the total project cost. The proposed CPI further differentiates priority among high-cost work items by integrating cost contribution, zone dominance, ABC classification, and optional technical risk, enabling more targeted prioritization of AHU isolation, air-conditioning, sanitation, piping, aluminium works and nurse station components. Unlike conventional Pareto-ABC analysis, which prioritizes work items solely based on cumulative cost, the proposed WBS-Pareto-ABC-CPI framework provides a structured decision-support model that links cost concentration with managerial control priorities during the pre-construction stage. The framework contributes to construction management by transforming conventional BoQ data into a practical and replicable tool for preventive cost, procurement, quality, schedule and safety control that can be applied tohospital rehabilitazion and other public-building projects.

Abstract

The absence of long-term observed hydrological data poses a significant challenge for urban flood management. This study addresses data scarcity in the Kedungsari reach of the Senapelan River, Pekanbaru, Indonesia, by combining 1D steady-flow hydraulic modeling with empirical hydrological estimation to determine the channel's critical bankfull capacity and its corresponding return period. The model isolated the maximum safe bankfull capacity at 17.20 m³/s, identifying Cross-Section 4 as the primary hydraulic bottleneck. Mapping this physical capacity onto the regional design flood frequency curve revealed that the existing channel corresponds to a low return period of approximately 1.5 years. Consequently, the channel is severely undersized, failing to contain a standard 2-year frequent flood (24.70 m³/s) or the legally mandated 10-year extreme event (33.26 m³/s).
