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

Perubahan fungsi bangunan hunian menjadi perkantoran dapat meningkatkan beban struktur dan memengaruhi kinerja pondasi tiang bor. Penelitian ini bertujuan mengevaluasi kapasitas dukung dan penurunan pondasi borepile pada gedung 12 lantai di Kalimantan Timur berdasarkan reaksi struktur atas dan pemodelan numerik geoteknik. Analisis struktur atas dilakukan menggunakan ETABS v22 untuk memperoleh reaksi tumpuan, sedangkan analisis interaksi tanah-pondasi dilakukan menggunakan PLAXIS 3D dengan model konstitutif Mohr-Coulomb. Data tanah berdasarkan hasil SPT hingga kedalaman 30 m menunjukkan nilai rata-rata N-SPT 47,78 dan diklasifikasikan sebagai tanah sedang (kelas situs SD). Hasil ETABS menunjukkan reaksi vertikal terbesar pada kondisi perkantoran sebesar 6546,63 kN atau sekitar 654,66 tonf. Hasil analisis pondasi menghasilkan kapasitas dukung ultimit tiang tunggal 579,87 ton, kapasitas izin tiang tunggal 231,95 ton, dan kapasitas izin kelompok empat tiang 927,80 ton. Penurunan maksimum akibat beban kerja sebesar 1,44 cm dan meningkat menjadi 3,38 cm setelah konsolidasi 730 hari. Nilai tersebut masih berada di bawah batas izin SNI 8460:2017, sehingga pondasi borepile dinyatakan aman dan layak digunakan untuk perubahan fungsi bangunan

Abstract

Indonesia is located in a region with high seismic activity, making earthquake-resistant structural design an essential consideration in building construction. Cold-formed steel (CFS) has become an attractive structural material due to its lightweight characteristics, high strength-to-weight ratio, ease of fabrication, and construction efficiency. However, its relatively thin cross-section requires further evaluation of its seismic performance, particularly for multi-story buildings. This study aims to analyse the dynamic characteristics and seismic performance of a three-story cold-formed steel frame structure subjected to earthquake loading based on SNI 1726:2019 using ANSYS through the Finite Element Method (FEM). The research involved structural modelling, modal analysis, and earthquake load analysis using the Equivalent Lateral Force (ELF) method. The evaluated parameters included natural frequency, vibration period, structural deformation, interstory drift, and maximum structural stress. The analysis results show that the first-mode natural frequency is 9.9662 Hz with a fundamental vibration period of 0.1003 s. The maximum deformation obtained is 0.169 mm, while the maximum interstory drift reaches 0.0066 mm, which is significantly lower than the allowable limit of 72 mm specified in SNI 1726:2019. Furthermore, the maximum structural stress is 1.5202 MPa, considerably lower than the yield strength of G550 steel (550 MPa), indicating that the structure remains within the elastic range. These findings demonstrate that the analysed three-story cold-formed steel frame possesses adequate stiffness, satisfies the seismic performance requirements of SNI 1726:2019, and can safely withstand the applied earthquake loading. Keywords: Cold-Formed Steel; ANSYS; Finite Element Method; Seismic Performance; Earthquake Load.

Abstract

The substructure of a bridge plays a vital role in ensuring the stability and safety of the bridge structure by transferring loads from the superstructure to the supporting ground. The construction of the Cibeet River Bridge at STA 0+952 in Deltamas City requires a reliable foundation system due to varying subsurface soil conditions. Therefore, evaluating the bearing capacity and structural performance of the bridge abutments and bored pile foundations is crucial. This study aims to analyze the results of soil investigations obtained from field and laboratory tests, determine the bearing capacity of the bored pile foundations, and evaluate the structural design of the bridge abutments. The research methodology involved a literature review, collection of bridge design data, and analysis of geotechnical investigation data, including Standard Penetration Tests (SPT), Cone Penetration Tests (CPT), borehole logs, and laboratory tests. The structural analysis considered dead loads, earth pressure, additional loads, traffic loads, braking loads, and seismic loads acting on the abutments. The research results indicate that the selected bored pile foundations provide sufficient bearing capacity to support the applied structural loads, while the abutment design meets the required structural strength and stability criteria. Strengthening analyses for the abutment walls, pile heads, and bored piles also indicate that the designed reinforcements meet the structural requirements under the applicable load combinations. Overall, the planned bridge substructure is capable of safely transferring loads to the foundation system and is considered suitable for implementation in the Cibeet River Bridge project. Keywords: Bridge, Abutment, Bored Pile, Bearing Capacity, Soil Investigation.

Abstract

Construction projects frequently encounter challenges related to budget management, project delays, and resource procurement, all of which may significantly influence project performance. This study aims to analyze the direct and indirect relationships among these factors using an integrated Statistical Package for the Social Sciences (SPSS) and Partial Least Squares Structural Equation Modeling (SEM-PLS) approach. A quantitative research design was employed using questionnaire data collected from 150 construction professionals representing contractors, consultants, project managers, supervisors, and engineers. IBM SPSS 26.0 was utilized for descriptive statistics, validity, reliability, normality, multicollinearity, and multiple regression analyses, while SmartPLS 4 was used to evaluate the structural model. The results demonstrate that budget management has the strongest direct effect on construction project performance (β = 0.796, p < 0.001). Resource procurement exhibits the greatest influence on budget management (β = 0.834, p = 0.001), whereas project delays significantly affect both budget management and project performance. Furthermore, the proposed structural model satisfies the goodness-of-fit criteria (SRMR = 0.045; NFI = 0.945), indicating an acceptable model fit. These findings highlight the importance of effective financial planning and resource management in improving construction project performance and provide empirical evidence for project managers in developing strategies to minimize delays and optimize project outcomes.

Abstract

The construction of Nutrition Service Units (SPPG) is a strategic component of Indonesia’s Free Nutritious Meals Program, requiring effective cost-risk management and quality control to ensure successful project delivery. These challenges become more significant in island regions where transportation constraints, material availability, and unpredictable weather increase project uncertainty. This study aims to analyze cost-risk characteristics, evaluate quality-control performance, identify factors affecting cost deviation, and develop an over-budget prediction model for SPPG construction projects in the Selayar Islands. A quantitative research design was employed using 88 work-item observations representing preparatory, structural, architectural, mechanical-electrical-plumbing, and infrastructure works. Statistical analyses included descriptive statistics, Shapiro–Wilk normality testing, Cronbach's Alpha reliability analysis, correlation analysis, independent sample t-test, one-way ANOVA, multiple linear regression, binary logistic regression, and K-Means clustering. The findings indicate that the overall project cost deviation was −0.42% of the contract value, although 25.0% of work items experienced cost overruns. Work categories significantly influenced cost deviation, whereas construction methods showed no significant effect. Cost risk exhibited a very strong negative relationship with quality-control performance (ρ = −0.918). The proposed statistical framework provides practical support for prioritizing risk control in future SPPG construction projects under island construction conditions.

Abstract

The LINAC and Brachytherapy bunkers constructed at RSUD Raden Mattaher Jambi are part of a strategic healthcare development initiative by the Jambi Provincial Government. These bunkerstructures possess specialized characteristics to ensure maximum protection against radiationexposure, utilizing thick reinforced concrete and, in some areas, lead-lined layers. RadiationShielding Concrete (RSC), also known as heavyweight concrete, is used for this purpose, typicallyhaving a density greater than 2600 kg/m³. Designed to attenuate gamma rays, X-rays, andneutrons, the effectiveness of RSC depends significantly on its density. Studies indicate thatconcrete with densities between 3012–3820 kg/m³ achieves linear attenuation coefficients (μ)ranging from 0.224 to 0.265 cm⁻¹, demonstrating high shielding capability. During construction,deviations occurred between the Detail Engineering Design (DED) and the actual fieldimplementation (As-Built Drawing or ABD) due to site conditions and safety considerations. Thisstudy aims to analyze the structural differences between DED and ABD. Structural analysis wasconducted using ETABS software to obtain internal forces in the structural elements, followed bymanual verification. Results show that the columns are capable of resisting axial loads andmoments, with reinforcement ratios within the required 1%–6% of gross concrete area (Ag).Variations in internal forces were identified between DED and ABD. In the floor slab analysis, theDED design failed to meet flexural strength requirements (Mu > ϕMn), while the ABD designachieved sufficient nominal capacity (Mu < ϕMn), enhancing the structure’s performance underservice loads.
