Abstract

Kawasan wisata Pantai Kuta merupakan salah satu destinasi unggulan di Bali dengan melihat setiap tahun banyaknya wisatawan baik dari dalam negeri maupun mancanegara yang berkunjung ke Pantai Kuta. Namun hal tersebut juga menjadi salah satu tantangan dalam sektor Transportasi yaitu tingginya aktifitas kendaraan bermotor sehingga menimbulkan permasalahan kemacetan dan menurunnya kualitas lingkungan. Selain itu banyak masyarakat dan wisatawan yang beraktivitas salah satunya dengan bersepeda, dikarenakan banyaknya pengguna sepeda menggunakan ruas jalan utama di kawasan Pantai Kuta sehingga akan menimbulkan permasalahan lalu lintas khususnya di bidang keselamatan. Dari banyakanya ruas jalan Kawasan Wisata Pantai Kuta, akan dipilih beberapa ruas jalan yang akan direncanakan sebagai lajur khusus sepeda. Rute sepeda yang terpilih dihitung analisa kinerja setelah sebagian badan jalan digunakan sebagai lajur khusus sepeda serta usulan penempatan rambu dan marka. Pengolahan data analisa yang dilakukan yakni mengenai unjuk kerja kondisi eksisting sebelum adanya lajur sepeda dan kondisi rekomendasi setelah adanya lajur sepeda meliputi kapasitas, V/C ratio,serta tingkat pelayanan jalan tersebut. Dari perhitungan analisa didapat 3 Rute terpilih dengan analisa pertimbangan pengaruh sampai dengan 5 tahun kedepan. Lajur sepeda yang direncanakan ialah dengan lebar 1,6 meter ditandai dengan marka hijau dan dibatasi dengan marka menerus. Penyediaan fasilitas parkir ditempatkan di setiap lokasi tarikan perjalanan.

Abstract

The construction of high-rise buildings is influenced by land limitations and advances in construction technology. However, these structures present more complex technical risks, particularly in earthquake-prone regions such as Indonesia. Earthquake-resistant structural design serves as a preventive approach to minimize potential casualties and post-disaster losses, rather than to create completely earthquake-proof buildings. Concrete and steel are commonly used structural materials in high-rise buildings due to their high strength, but their selection also considers various other parameters beyond strength alone. This study analyzes the comparative seismic performance of high-rise building models using steel and reinforced concrete materials. The analysis focuses on base shear force, inter-story drift response, and the impact of P-Delta effects using the response spectrum method in ETABS v.21 software. The results show that the total base shear force (Vtotal) in the Reinforced Concrete Structure (RCS) model is 28,979.31 kN, while in the Steel Structure (SS) model it is 8,133.61 kN. The higher value in the RCS model is due to its greater structural weight and shorter structural period. Both models meet the allowable inter-story drift limits, with the RCS model showing smaller displacements: 50.001 mm (X direction, 10th floor) and 41.058 mm (Y direction, 9th floor), compared to the SS model’s 50.930 mm (X direction, 8th floor) and 40.700 mm (Y direction, 7th floor). Furthermore, the P-Delta effect in both models remains within safe limits; however, the RCS model exhibits smaller maximum values of 0.0220 and 0.0185 compared to the SS model’s 0.0649 and 0.0530, indicating better seismic stability in the reinforced concrete structure.

Abstract

Castellated steel is a steel beam that has a hexagonal hollow web element. One of the cases that often occurs in castellated steel structures is buckling. This study takes a case study of ramp door construction made of castellated steel. The ramp door construction experienced buckling damage after a load test. Analysis was carried out on four ramp door models with loading resembling the actual conditions of the bridge according to SNI 1725-2016. The first modeling uses a 900x200x11x17 castellated main beam without the addition of stiffeners. The second modeling with the addition of stiffeners at each distance between castellated holes. The third modeling closes all holes without the addition of stiffeners. The fourth modeling closes all holes with the addition of stiffeners at each distance between castellated holes. The analysis was carried out using the finite element method. This study aims to determine the effect of stiffeners and castellated hole covers on deformation values, equivalent stress and buckling eigenvalues. From the analysis of the effect of stiffener (second model) for the deflection value decreased by 0.62%, the stress value increased by 4.04%, the buckling eigenvalue increased by 144.94%. The effect of castellated cover (third model) for the deflection value decreased by 8.69%, the stress value decreased by 19.71%, the buckling eigenvalue increased by 12.75%. The effect of stiffener and castellated cover (fourth model) for the deflection value decreased by 11.18%, the stress value decreased by 20.15%, the buckling eigenvalue increased by 153.98%.

Abstract

Amidst global food security challenges and post-pandemic economic fluctuations, the development of robust agricultural infrastructure has become an inevitable national priority, as outlined in Presidential Instruction Number 2 of 2025. However, fiscal realities at the regional level often present a paradox: the need for infrastructure rehabilitation is increasing while fiscal space is narrowing. This research highlights this phenomenon in Serang Regency, where the budget trend for irrigation management shows a significant decline from 2021 to 2025. This thesis proposes and tests the effectiveness of the Supplied by Owner (SBO) procurement method as a technocratic solution to bridge this gap. Through a case study approach on the Ciwates Irrigation Network Improvement project, this research conducts an in-depth comparative analysis of two key variables: construction cost efficiency and the optimization of Domestic Component Level (TKDN) in concrete works. The methodology combines contract document analysis, market price simulation, and material supply chain audit. The research results reveal empirical findings that the implementation of SBO is capable of generating a cost efficiency of 3.04% (equivalent to IDR 57,380,000.00) from a total conventional project value of IDR 1,886,459,000.00 to IDR 1,829,079,000.00. More significantly, this method proved to be a strong catalyst for increasing TKDN through the use of PT. Conch Cement Indonesia products, recording an increase of 9.21 percentage points from 52.18% to 61.39%. These findings confirm that SBO is not merely a savings mechanism, but a strategic instrument for quality control and the affirmation of national industrial policy. This study recommends the institutionalization of SBO in regional procurement regulations for material-intensive projects.

Abstract

The implementation of VE in the construction sector is an approach carried out systematically by a team from many disciplines that focuses on value and function. The implementation of VE in construction projects has the potential for significant savings from the project budget. In the construction world, project owners are often faced with various constraints such as budget constraints, increasing material costs, and the need for time efficiency. VE offers a solution to overcome these constraints with a functional analysis-based approach that aims to increase value by reducing unnecessary costs without reducing the quality of the final product. The implementation of VE carried out in construction projects, the techniques and alternatives used vary, this is due to the approach used, cultural conditions, and different procurement systems. The purpose of this study is to identify VE practices in Indonesia, examine the success factors in these practices, knowledge and experience of VE, and the constraints often faced in VE practices. The research method was carried out by distributing questionnaires to respondents who had knowledge of VE. The data obtained from the questionnaire were analyzed using descriptive analysis. The results of the analysis show that the implementation of VE in Indonesia is carried out on projects that are being proposed and on projects that are underway, the knowledge and experience of construction actors are the main success factors, construction actors have sufficient knowledge about VE, and the lack of knowledge about VE is the main obstacle in the implementation of VE in Indonesia.

Abstract

The ongoing construction of the project requires a fairly large allocation of funds, and it is necessary to reconsider whether the design used is optimal. This can be done by reviewing the project planning design so that it is possible to make cost savings by identifying and reducing unnecessary costs without reducing the level of quality, reliability and function of the project itself. Carrying out value engineering techniques, namely carrying out cost analyzes by comparing the costs per item with the details of each job from the contractor's offer to find the cheapest price up to the negotiation stage for cost savings and efficiency. The AHP (Analytic Hierarchy Process) method can be used as a solution to problems in finding decisions, and for assessment using a Likert scale questionnaire. Value engineering in the planning review by taking a case study of an ongoing project in the Pengambengan area of ​​Bali, namely the integrated fishing port project. There are 3 alternatives compared to the planning budget, namely breakdown analysis techniques (Work Breakdown Structure), cost modeling techniques (Cost modeling techniques), and Delphi techniques (Delphi Teqhnique). In value engineering, you can see the price comparison for each work item for planning reviews. The results for the final review based on value engineering RAB planning estimate Rp. 1,626,877,637,500. The stages in the AHP method analysis are determining the objective of the analysis, namely value engineering in selecting contractors, determining the analysis criteria: Cost Budget Plan, Detailed Drawings, Technical Specifications, and Implementation Time, as well as determining alternative options

Abstract

Engineering, Procurement, and Construction (EPC) projects face complex challenges such as multidisciplinary coordination, tight schedules, material procurement risks, and design change dynamics, which require the crucial role of Construction Management Consultants (CMCs) in ensuring the achievement of time, cost, and quality targets. This study analyzes the influence of expert competence, quality management, and communication on CMC performance in the coal processing facility construction project in Tanjung Enim, South Sumatra. The study employs a quantitative approach using research instruments developed based on indicators of expert competence, quality management, and communication. Instrument validation was conducted using item analysis with Pearson's product-moment correlation coefficient, while reliability was measured using Cronbach's Alpha coefficient. Data were analyzed using partial correlation and multiple regression techniques. The results of the study indicate: (1) Expert competence has a significant positive effect on KMK performance (ry1 = 0.377 > 0) with the regression equation Ŷ = 19.843 + 0.144 X1; (2) Quality management has a significant effect (ry2 = 0.543 > 0) with the equation Ŷ = 19.040 + 0.174 X2; (3) Communication makes an important contribution (ry3 = 0.471 > 0) with the equation Ŷ = 19.590 + 0.152 X3. Multiple regression analysis shows that the three variables together explain 82% of the variance in performance (ry123 = 0.9272 > 0) with the equation Ŷ = 3.9547 + 0.200 × X1 + 0.1995 × X2 + 0.2237 × X3. These findings confirm that the performance of construction management consultants on EPC projects is significantly influenced by expert competence, quality management, and communication. The study recommends the need for standardization of competencies, implementation of an integrated quality management system, and development of an effective communication model to improve the performance of CMC on similar projects.

Abstract

Construction project delays are one of the main problems in the construction service industry in Indonesia, which have an impact on increased costs, decreased work quality, and disruption to project completion schedules. The Penjaringan Flats Revitalization Project (Towers A, B, E, and F) in North Jakarta is one example of a project that experienced time constraints due to the complexity of implementation and external factors such as the Covid-19 pandemic. This study aims to identify the factors that influence delays in the Penjaringan Flats Revitalization Design-Build Integrated Construction Services project. The research method used is a qualitative approach with descriptive analysis based on field data, supervision reports, meeting minutes, and project documentation during the 2019–2021 period. The results of the study show that there are nine main variables causing delays, namely situational factors, managerial factors, contract and document scope, planning and scheduling, materials, labor, site characteristics, control, and the Covid-19 pandemic. Of these nine variables, the five dominant factors that significantly influenced delays were cost factors, unexpected events, the experience of supervisors or field managers, and communication between contractors and consultants and between owners and contractors. The conclusion of this study confirms that cost efficiency, external risk management, and good communication and workforce competence are key factors in preventing construction project delays in the future.

Abstract

Population growth and high economic activity in the DKI Jakarta area have led to a significant increase in vehicle volume and traffic congestion. These conditions require an efficient, safe, and environmentally friendly mass transportation system in order to reduce the public's dependence on private vehicles. One of the national strategic projects designed to address this challenge is the construction of the Jakarta Light Rail Transit (LRT) Phase 1B. In the construction of the LRT, time and cost efficiency are crucial factors that determine the success of the project. This study aims to analyze and compare the efficiency of two methods of installing steel reinforcement (rebar), namely the prefabricated joint coupler system and the conventional method without couplers. The study uses a quantitative descriptive approach by collecting secondary data in the form of Unit Price Analysis (AHSP), project progress reports, and field observations. The analysis was conducted on labor productivity, material costs, and implementation time. The results showed that the rebar installation method with prefabricated joint couplers was able to save 15-20% of steel material, reduce the duration of work by around 25-30%, and significantly reduce labor costs compared to the conventional method. In addition, the prefabrication system provides more consistent work quality, minimizes the risk of delays, and improves work safety. Based on these results, it is concluded that the application of the prefabricated joint coupler method is more effective and efficient in both technical and economic aspects for the Jakarta LRT Phase 1B construction project and can be recommended for similar infrastructure projects in the future.
