Abstract

Sektor konstruksi di Indonesia masih mencatat angka kecelakaan kerja yang tinggi, antara lain disebabkan oleh kurang efektifnya metode pelatihan keselamatan konvensional. Penelitian ini bertujuan untuk mengembangkan sistem terintegrasi antara 8D Building Information Modeling (BIM) dan Virtual Reality (VR) untuk pelatihan simulasi keselamatan pekerja di proyek bangunan gedung. Dengan menggunakan metode studi literatur sistematis, penelitian ini mengidentifikasi, menganalisis, dan mensintesis konsep serta praktik terbaik yang relevan untuk membangun fondasi teoritis pengembangan sistem simulasi yang efektif. Hasil penelitian menunjukkan bahwa integrasi 8D BIM dan VR memungkinkan simulasi keselamatan yang imersif dan interaktif, meningkatkan identifikasi bahaya, memperkuat komunikasi kolaboratif antar pemangku kepentingan, serta mendukung pengambilan keputusan berbasis data. Sistem ini juga berkontribusi pada keberlanjutan proyek melalui efisiensi energi dan pengurangan limbah material. Namun, tantangan seperti tingginya biaya implementasi, keterbatasan infrastruktur VR, serta belum adanya standar evaluasi jangka panjang masih menjadi kendala. Simpulan penelitian ini menyatakan bahwa integrasi 8D BIM–VR berpotensi besar meningkatkan kesadaran keselamatan dan menurunkan angka kecelakaan konstruksi, meski diperlukan penelitian lanjutan secara eksperimental dan longitudinal untuk mengukur dampak jangka panjangnya.

Abstract

This study investigates the effect of using Parangtritis beach sand as fine aggregate and rice husk biochar as an additive on the stability and durability of Asphalt Concrete Wearing Course (AC-WC) mixtures. Parangtritis beach sand has abundant availability; however, its fine, rounded grains with high silica content result in low adhesion to asphalt. To improve performance, rice husk biochar was utilized as an additive. The research determined the Optimum Asphalt Content (OAC) using the Narrow Range method with asphalt variations of 4%, 5%, 6%, 7%, and 8%, and beach sand variations of 15%, 30%, and 45% by the weight of fine aggregate to obtain the Optimum Beach Sand Content (OBSC). The Marshall Stability Test was conducted with immersion periods of 0, 24, 72, 168, and 336 hours to evaluate stability and durability parameters, including the First Durability Index (FDI), Second Durability Index (SDI), and Retained Strength Index (RSI). The results showed that the mixture containing Parangtritis beach sand and rice husk biochar met the 2018 Bina Marga specifications, with an OAC of 6% and an OBSC of 24.25%. The addition of 4% biochar produced the best performance, achieving a stability of 1,492.59 kg and RSI values of 91.2% (24 hours) and 64.3% (336 hours), indicating a significant improvement in the mixture’s stability and durability.

Abstract

Low-speed urban road sections such as intersections, bus bays, parking areas, and braking zones are subjected to high contact stresses, frequent braking, and moisture exposure, conditions that often lead to rutting, deformation, and strength degradation in conventional asphalt wearing courses. Although cobblestone pavements have historically demonstrated durable performance in similar environments, their application remains largely based on empirical practice rather than systematic mechanical comparison with asphalt materials. This study proposes a strength-normalized performance framework to compare the mechanical suitability of cobblestone and dense-graded asphalt concrete wearing courses for low-speed urban applications. Cobblestone performance was characterized using aggregate crushing, impact, and abrasion tests representing compressive resistance, impact toughness, and abrasion durability. Asphalt mixture performance was evaluated using Marshall stability, indirect tensile strength, and unconfined compressive strength to represent shear, tensile, and compressive resistance. Test results were normalized into dimensionless indicators and integrated into composite strength indices reflecting dominant pavement stress modes. Results show that cobblestone achieved a strength index of 1.317, compared with 1.102 for asphalt under dry conditions, indicating approximately 20% higher resistance to compression- and wear-dominated loading. Under soaked conditions, the cobblestone index decreased to 1.152, approaching asphalt performance

Abstract

This research paper is to study the effect of using Rubber Bearing as Base Isolator. Two analyses are performed in this study. The first analysis is using a whole building structure to be calculated its period and to be estimated its pseudo acceleration for both fixed and isolated bases. The second analysis, period calculation and estimation of pseudo acceleration is using a single column of the building structure. Method of analysis is using basic vibration formulas. The calculated parameters are stiffness of the structure, damped frequency, undamped natural frequency and period of vibration.  Using response spectra of the building, pseudo acceleration is estimated by plotting vibration period for both fixed and isolated supports. Trial-and-Error processes are needed to find where along response spectra three lines types two pairs of the coordinate of period and pseudo acceleration reveal the increasing value of period and decreasing value of acceleration.   Comparing the pseudo acceleration of fixed and isolated base, for the first analysis, the pseudo acceleration decreases up to 53,85 %. Pseudo acceleration decreases by 51,79 % for the second analysis. The decreasing value of earthquake acceleration is only possible when both fixed and isolated base structural periods fall in the Curved down line in the response spectrum diagram.

Abstract

Abstract: This study aims to analyze the lifting plan calculation in offshore pile installation works for breakwater construction at the East Java Refrigerated LPG Terminal Project Phase 2. The research employs a descriptive quantitative approach through direct field observation of lifting activities using a crawler crane operating on a working barge. The analysis includes the calculation of total lifting load, dynamic load correction using the dynamic amplification factor (DAF), effective crane capacity based on the load chart, as well as evaluation of crane utilization and safety factor as indicators of operational safety. The results indicate that the lifting of steel pipe piles from the service barge to the working barge achieved a crane utilization of 65.29% with a safety factor of 1.53, representing a safe and optimal condition. In the pile-to-launch lifting process using a pile gripper, utilization increased to 81.38% with a safety factor of 1.23, indicating a near-critical operational condition. Meanwhile, lifting operations involving the vibro hammer and impact hammer showed utilization levels of 49.25% and 75.18%, respectively, with safety factors above 1.33, indicating safe to highly safe conditions. Overall, the findings demonstrate that lifting plan performance is strongly influenced by equipment configuration, lifting load, and offshore environmental conditions, highlighting the need for comprehensive technical evaluation to ensure operational safety and efficiency.

Abstract

Traffic performance in a road network is significantly influenced by traffic flow at intersections. Area D, a signalized intersection located in Dodoma City,Tanzania experiences traffic congestion during peak hours, causing excessive vehicle delays when signals are in operation. The main objective of the study is to evaluate traffic performance of the existing intersection using Highway Capacity Manual (HCM 2010) and PTV VISSIM simulation during peak periods. Vehicle flow was measured during morning and evening peak periods, specifically at 06:00 to 10:00 AM and from 04:00 to 06:00 PM. The traffic composition during the morning peak consisted of light vehicles (46.95%), motorcycles (33.78%), and heavy vehicles (19.27%), while during the evening peak it consisted of light vehicles (46.46%), motorcycles (36.06%), and heavy vehicles (17.48%). Analysis using HCM 2010 indicated that the average delay was 55.16 pcu/sec during the morning peak and 115.14 pcu/sec during the evening peak. The average queue lengths were 131.2 m and 327.4 m, with Level of Service E and F during morning and evening peak hours, respectively. PTV VISSIM Version 11 results showed higher delays of 99.67 pcu/sec and 149.14 pcu/sec. Three improvement scenarios were evaluated using a micro-simulation approach. The third scenario, combining traffic signal optimization and geometric improvements, was identified as the most effective. This scenario reduced delays to 21.27 pcu/sec and 29.86 pcu/sec, decreased queue lengths to 29.86 m and 89.45 m, and improved level of service to B and C during morning and evening peak hours.

Abstract

Accurate quantity take-off is essential for reliable construction cost estimation, particularly in reinforced concrete works, which involve complex and error-prone calculations. This study evaluates the accuracy of BIM 5D-based quantity take-off and examines cost deviations compared to conventional contractor estimations. A three-story dormitory building was modeled using BIM 5D (Cubicost), and the results were validated against manual analytical calculations. The validation shows strong agreement, with a maximum deviation of 0.75% and a high linear correlation across concrete, reinforcement, and formwork quantities. A comparative analysis with the contractor’s Bill of Quantity reveals a cost difference of approximately 3.4%, with the contractor’s estimate being higher. This deviation is primarily attributed to simplifications in conventional methods, including double counting at element interfaces, generalized reinforcement detailing, and the inclusion of material allowances. In contrast, BIM 5D enables a more integrated and precise estimation by accounting for element interactions and optimizing reinforcement configurations. However, the results also highlight that BIM-based estimation is sensitive to modeling assumptions and parameter settings. Therefore, aligning BIM models with actual construction practices is essential to ensure reliable and applicable results. Overall, this study demonstrates the potential of BIM 5D to enhance the accuracy, consistency, and transparency of construction cost estimation.

Abstract

Abstract: Mass concrete pouring for raft foundations requires continuous execution to maintain structural integrity and prevent cold joints. This study aims to analyze productivity deviations in the mass concrete pouring of a 12,390 m³ raft foundation at Basement 3 of a high-rise building project in Jakarta. A descriptive quantitative approach with a case study method was employed using secondary data, including the baseline schedule, concrete pouring logs, truck mixer arrival records, and slump rejection data. Data were analyzed using S-Curve Overlay, throughput analysis, headway analysis, loss time analysis, and concurrent delay analysis. The results indicate that the actual pouring duration reached 69.3 hours, exceeding the planned duration of 53 hours by 16.3 hours (30.7%). The average actual productivity was 177.6 m³/h, which was 22.7% lower than the planned productivity of 230 m³/h. Logistical delays caused by unstable truck mixer headway accounted for the largest contribution, representing approximately 49% of the total schedule deviation. The remaining 51% resulted from concurrent operational factors, including extended pouring duration, slump rejection incidents, adverse weather conditions, equipment downtime, and performance degradation due to equipment and workforce fatigue. These findings emphasize that successful large-scale mass concrete pouring depends on the synchronization of concrete supply stability, equipment reliability, material quality control, and field resource readiness.. Keywords: mass concrete, productivity, raft foundation, headway, concurrent delay Abstrak: Pekerjaan pengecoran mass concrete pada raft foundation memerlukan pelaksanaan secara kontinu untuk menjaga integritas struktur dan mencegah terjadinya cold joint. Penelitian ini bertujuan menganalisis deviasi produktivitas pada pekerjaan pengecoran mass concrete raft foundation Basement 3 dengan volume 12.390 m³ pada proyek gedung bertingkat tinggi di Jakarta. Penelitian menggunakan pendekatan kuantitatif deskriptif dengan metode studi kasus berdasarkan data sekunder berupa baseline schedule, concrete pouring log, logbook kedatangan truck mixer, dan data slump reject. Analisis dilakukan menggunakan metode S-Curve Overlay, throughput analysis, headway analysis, loss time analysis, dan concurrent delay analysis. Hasil penelitian menunjukkan bahwa durasi aktual pengecoran mencapai 69,3 jam, lebih lama 16,3 jam atau 30,7% dibandingkan durasi rencana 53 jam. Produktivitas rata-rata aktual tercatat sebesar 177,6 m³/jam, lebih rendah 22,7% dibandingkan produktivitas rencana sebesar 230 m³/jam. Keterlambatan logistik akibat ketidakstabilan headway armada truck mixer memberikan kontribusi terbesar, yaitu sekitar 49% dari total deviasi durasi. Sementara itu, 51% sisanya disebabkan oleh faktor operasional yang terjadi secara bersamaan, meliputi pembengkakan durasi penuangan, kejadian slump reject, gangguan cuaca, downtime peralatan, serta penurunan kinerja akibat fatigue pada alat dan tenaga kerja. Hasil penelitian menegaskan bahwa keberhasilan pengecoran mass concrete sangat bergantung pada sinkronisasi antara stabilitas suplai beton, keandalan peralatan, pengendalian mutu material, dan kesiapan sumber daya lapangan.

Abstract

Bendungan yang telah selesai dibangun akan mengalami tekanan dari beban sendiri dan air waduk yang dapat menyebabkan bendungan mengalami deformasi. Deformasi vertikal bendungan pasca konstruksi pada permukaan dapat dipantau dengan instrumentasi patok geser. Analisis deformasi vertikal difokuskan pada arah sumbu z sebagai data pengukuran yang menunjukkan tren penurunan pada permukaan tubuh bendungan. Hasil dari pengukuran dibandingkan dengan kriteria penerimaan dari Hunter and Fell, ICOLD, Sowers, Sherard, dan analisa berdasarkan Settlement Index (SI). Tujuan dari penelitian ini adalah untuk menganalisis perilaku deformasi vertikal Bendungan Tukul pasca konstruksi dengan menganalisis besaran penurunan yang terjadi terhadap kriteria penerimaan tersebut. Hasil analisis deformasi vertikal Bendungan Tukul pasca konstruksi dalam periode 3 (tiga) tahun berdasarkan patok geser dari beberapa kriteria didapatkan hasil beberapa instrumen memiliki nilai abnormal atau di bawah kriteria penerimaan, sebagian besar instrumen memenuhi kriteria sehingga dianggap normal. Namun, dalam hal kriteria yang abnormal terjadi pada beberapa instrumen bukan berarti bendungan dianggap tidak aman. Hasil analisis SI, keseluruhan instrumen memenuhi nilai di bawah 0,02 dengan nilai 0,001 s.d. 0,015, sehingga penurunan yang terjadi dalam kategori normal.

Abstract

Kawasan Heritage Kayutangan di Kota Malang mengalami kemacetan parah akibat peningkatan volume kendaraan dan aktivitas wisata yang tidak seimbang dengan kapasitas jalan. Sejak Januari 2023, Pemerintah Kota Malang menerapkan sistem satu arah melalui Peraturan Wali Kota No. 39 Tahun 2023 sebagai upaya rekayasa lalu lintas. Penelitian ini bertujuan efektivitas efektivitas kebijakan tersebut menggunakan parameter kuantitatif, meliputi volume lalu lintas, kapasitas jalan, derajat kejenuhan (DS), tingkat pelayanan (LOS), frekuensi penyeberangan pejalan kaki, parkir pembohong, dan data kecelakaan. Metode penelitian menggunakan pendekatan observasi lapangan selama empat minggu pada tahun 2025 di koridor Jalan Basuki Rahmat (Jl. Mojopahit hingga Jl. Semeru), dengan mengacu pada Pedoman Kapasitas Jalan Indonesia (PKJI). Hasil penelitian menunjukkan volume lalu lintas sebesar 1.615 kendaraan/jam dan kapasitas jalan sebesar 2.830 kendaraan/jam, sehingga diperoleh DS sebesar 0,57 yang secara teoritis berada pada tingkat pelayanan C. Namun, kondisi faktual menunjukkan LOS berada pada level E akibat tingginya hambatan samping. Selama pengamatan, tercatat 135 pejalan kaki spontan per jam, 217 kendaraan parkir pembohong per jam, lebar trotoar kurang dari 1,2 meter, serta enam kejadian kecelakaan pada periode 2022-2024. Sistem satu arah menghasilkan arus lalu lintas yang kontinu tanpa jeda alami untuk penyeberangan, sehingga meningkatkan potensi konflik antara kendaraan dan pejalan kaki. Oleh karena itu, diperlukan intervensi berbasis keselamatan berupa penguatan zebra cross dengan penenangan lalu lintas , optimalisasi serta penataan parkir perifer. Intervensi tersebut diharapkan dapat meningkatkan keselamatan dan kualitas pelayanan kawasan secara berkelanjutan
