Abstract

Jalan Majalengka-Rajagaluh is a road located in several sub-districts that is a link to the city and one of the connecting roads to Cirebon City. This design planning began in Cigasong sub-district and continued to Rajagaluh sub-district with a length of 5.3 kilometers on the Majalengka-Rajagaluh road. The results of the geometric design are visualized in the form of drawings using AutoCAD 2D. The design speed (Vd) is set at 60 km/h with a horizontal curve radius of 358 m, a maximum slope of 4%, and an elevation (e max) of 8%. Based on this design criterion, a spiral curve with a circular arch length (Lc) of 74,996 m was obtained. Furthermore, the results of the calculation of the vertical alignment of the length (L) of one type of convex curve in the PPV are also calculated.

Abstract

Cable-stayed bridges with box girders are essential innovations in civil engineering, especially for long-span structures. These bridges, reinforced with prestressed cables and box girders, are designed to handle significant loads but remain vulnerable to aerodynamic forces, particularly wind. The vulnerability is measured using the Pb parameter, as defined by the Ministry of Public Works (2015), which helps determine the windbreak structures needed for stability. This study analyzes the aerodynamic stability of bridge decks with widths of 8 m, 13 m, and 19 m on a 420 m bridge, featuring a 220 m main span and two 100 m side spans. The results reveal that the larger the deck width-to-span ratio, the higher the structure's natural frequency, which improves stability. The natural frequency values were recorded at 0.3 Hz for a 7 m deck (3.2%), 0.43 Hz for a 12 m deck (5.48%), and 0.53 Hz for an 18 m deck (8.2%). The most stable span ratio was found with the 18 m deck, with a Pb value of 0.04, showing minimal wind load effects. Moreover, a larger deck width enhances aerodynamic stability and extends the bridge’s service life by reducing damage risk from wind loads.

Abstract

Transformasi Bandar Udara Fatmawati Soekarno menjadi bandara internasional menuntut penyesuaian teknis terhadap ketebalan perkerasan landas pacu (runway) agar mampu melayani operasional pesawat berbadan besar seperti Boeing 767-300 dan Airbus A330-300. Kajian ini bertujuan untuk mengevaluasi ketebalan runway eksisting dan merancang ketebalan yang sesuai menggunakan dua pendekatan, yakni metode manual berdasarkan pedoman Federal Aviation Administration (FAA) dan perangkat lunak FAARFIELD. Hasil evaluasi menunjukkan bahwa perkerasan eksisting dengan total tebal 120 cm cenderung overdesain. Perhitungan manual menghasilkan total tebal 96,52 cm, sedangkan FAARFIELD menunjukkan desain lebih efisien sebesar 73,41 cm. Pesawat Boeing 737-800 ditetapkan sebagai pesawat rencana (design aircraft) karena memiliki frekuensi keberangkatan tertinggi dan kontribusi kerusakan tertinggi terhadap struktur perkerasan, sementara Boeing 767-300 digunakan sebagai pesawat pengecekan (check aircraft). Selain ketebalan, analisis juga merekomendasikan perpanjangan runway dari 2.285 meter menjadi minimal 2.750 meter agar dapat memenuhi kebutuhan operasional pesawat berbadan lebar. Dengan hasil ini, dapat disimpulkan bahwa runway eksisting telah memenuhi standar kekuatan namun perlu penyesuaian panjang untuk mendukung transformasi menjadi bandara internasional secara penuh.

Abstract

Fire is the out-of-control burning method of flammable substances, which includes wood, paper, plastic, fuel, or different substances, which produce heat, mild smoke, and toxic gases. Fires can occur, including woodland fires caused by lightning or because of human activities, along with building fires due to electric short circuits or errors in the use of fire. In building design, it is miles vital to apprehend the elements that cause fires and the fireplace's resistance to materials. Metal is a form of metallic made from a primary mixture of iron (Fe) and carbon (C), with the amount of carbon typically being much less than 2 per cent of its general weight. Steel is a very common fabric used in a spread of applications due to its aggregate of robust, long-lasting, and malleable properties.

Abstract

This study analyses the Implementation of the quality management system in the Light Rail Transit (LRT) Phase 1B project work on the Veledrome-Manggarai route spanning 6.4 km. The research employs Structural Equation Modeling-Partial Least Squares (SEM-PLS) and Customer Satisfaction Index (CSI) methods to analyze factors affecting quality management system implementation across four main work phases: borepile, pilecap, pier, and pierhead. Data were collected through structured questionnaires from 70 respondents comprising owners, contractors, and supervisory consultants. Results indicate that borepile work has the highest R² value (0.477), with material variables as the most dominant factor (path coefficient 0.294). The Fc 35Mpa concrete material indicator contributes most significantly (29%) to the quality management system. CSI analysis shows the highest stakeholder satisfaction level in pierhead work (90.88%) and lowest in pier work (79.78%). This research contributes to identifying critical factors in quality management systems for mass transportation infrastructure projects and provides a framework for quality performance evaluation in similar projects.

Abstract

Scour on bridge piers is a major problem in hydraulic engineering, reducing structural stability and accelerating foundation failure. This phenomenon occurs due to the interaction between airflow and bridge structural elements, resulting in the formation of scour holes that potentially reduce the bearing capacity of the soil around the piers. In areas with strong currents, seasonal changes in discharge, and unstable riverbed conditions, the risk of scour is even higher. The impact of scour damage not only reduces the operational lifespan of bridges but also leads to high rehabilitation costs and increases the potential for structural failure, which can endanger user safety. This study aims to analyze various scour mitigation methods that can be applied to bridge piers, including the use of protective materials such as riprap, gabions, and geotextiles; a geotechnical engineering approach that includes soil stabilization and riverbed contour modification; and the development of pier structural designs that are more adaptive to variations in flow patterns. The study was conducted through an in-depth literature review of previous research, an analysis of the effectiveness of each method under various hydrodynamic conditions, and an evaluation of the cost. The results of this study are expected to produce comprehensive recommendations regarding the most effective, efficient, and environmentally friendly mitigation strategies to reduce the rate of scour. Furthermore, this study provides direction in planning bridge designs that are more resilient to changes in flow and sedimentation, thereby extending the service life of the structure, reducing long-term maintenance costs, and improving user safety.
