ANALISIS KAPASITAS DUKUNG SPUN PILE PADA PILE SLAB
No full textThe project seeks to promote the National Economic Development (PEN), specifically targeting the enhancement and advancement of economic activities on Sumatra Island. One of the current projects is the construction of the Sicincin - Padang Toll Road Section (STA 0+000 - 36+600) of the Pekanbaru - Padang Toll Road. This segment of the highway is a component of the Trans Sumatra highway network on Sumatra Island. The bearing capacity and settlement design of the spun pile foundation at the pile slab STA 7+443 - STA 7+569 Sicincin - Padang Toll Road were recalculated based on soil investigation data derived from SPT (Standard Penetration Test) results, subsequently compared with the findings from the PDA Test (Pile Driving Analyzer) conducted in the field. Soft soil issues were identified at STA 7 + 443, leading to the formation of fissures and landslides. The issues arose from the interaction between a pile foundation plate and the capacity of a revolving pile foundation. The objective of the study is to determine the bearing capacity and settlement of the rotating pile foundation at STA 7 + 443 - STA 7 + 569 using Standard Penetration Test (SPT) results and to compare these findings with the field data obtained from the Pile Driving Analyzer (PDA) test. The analysis conducted involved the adjustment of the N-SPT value utilizing tables and graphs in compliance with SNI 1725-2016, SNI 8460-2017, and SNI 4153-2008. The settlement assessment reveals the most significant discrepancy in the Meyerhoff Method compared to the PDA Test, amounting to 5.32%. The pile's settlement is within the allowable limit of 60 mm; hence it is deemed safe.Untuk menunjang Pengembangan Ekonomi Nasional (PEN) dan khususnya pengembangan dan peningkatan kegiatan ekonomi di Pulau Sumatera. Salah satunya adalah Pembangunan Jalan Tol Seksi Sicincin - Padang (STA 0+000 – 36+600) Ruas Tol Pekanbaru - Padang. Ruas jalan tol ini merupakan bagian dari sistem jaringan jalan tol Pulau Sumatera (Trans Sumatera). Pada perencanaan ini, akan dihitung kapasitas dukung dan penurunan pada fondasi spun pile di pile slab STA 7+443 – STA 7+569 Jalan Tol Sicincin – Padang yang dihasilkan dari data penyelidikan tanah berupa uji SPT (Standard Penetration Test), kemudian dibandingkan dengan hasil PDA Test (Pile Driving Analyzer) di lapangan. Di STA 7+443, ditemukan masalah tanah lunak yang menyebabkan keretakan dan kelongsoran. Untuk mengatasi masalah ini, desain diubah menjadi pile slab dengan fondasi spun pile. Penelitian ini bertujuan menghitung kapasitas dukung dan penurunan fondasi spun pile pada pile slab di STA 7+443 – STA 7+569, berdasarkan uji SPT (Standard Penetration Test) dan membandingkan hasilnya dengan PDA Test (Pile Driving Analyzer) di lapangan. Analisis melibatkan koreksi nilai N-SPT menggunakan tabel dan grafik sesuai SNI 1725-2016, SNI 8460-2017, dan SNI 4153-2008. Evaluasi penurunan dengan penurunan pada PDA Test menunjukkan selisih terbesar pada Metode Meyerhoff sebesar 5,32%.

PEMBERHENTIAN PENGECORAN BETON UNTUK PEKERJAAN KONSTRUKSI LENTUR BERDASARKAN SNI 2847-2019
Get PDFThe presence of construction joints is an inevitable aspect of field concrete casting. These joints occur when fresh concrete is poured over hardened concrete, which can impact the strength and integrity of the concrete structure. This study aims to evaluate the placement of concrete joints according to SNI 2847-2019, which recommends placing them at one-third of the span of the beam. Testing was conducted on unreinforced concrete beams with two different joint locations. The concrete used had a water-cement ratio (w/c) of 0.5 and a maximum aggregate size of 25 mm, with the mix design following SNI 7656-2012. The test results indicate that joints placed at one-third of the span exhibit better flexural strength compared to those located at the span's ends. The average flexural strengths of beams without joints, those with joints at one-third of the span, and those with joints at one-third of the end span are 1.95 MPa, 1.56 MPa, and 0.98 MPa, respectively. These findings support the SNI 2847-2019 recommendation for placing concrete joints at one-third of the span of the beam

Analysis of Factors from The Parties That Are The Source of Causes of Contract Change in Infrastructure Project in Tangerang City-Banten Province
No full textIn the implementation of construction projects, problems cannot be avoided, one of which is contract change orders. This becomes a problem if it cannot be handled properly. Many factors cause change orders, including differences in understanding between stakeholders, owner requests, financial issues, scope differences, etc. SmartPLS software assessed and built a model with 13 causal change factors based on the literature review's structural relationships. The analysis technique in this research is the descriptive quantitative method. This method is used to obtain and examine structured and in-depth data that explains the behavior or circumstances being observed in depth and systematically. Data collected through the Google Form of 27 respondents to the Tangerang City PUPR Office project for improving and constructing city roads in the fiscal year 2023 were used in this study. In this study, two variables are the main focus in analyzing, in this case, the change order as an endogenous variable, and the project owner, contractor, and consultant as exogenous variables. The results of analysis using SEM-PLS found that the contractor variables have a significant effect on the occurrence of contract change orders by looking at the R-square value of 1.09 which can describe the amount of diversity that can be explained from the model built. The results of the analysis of the two types of variables are expected to be able to provide a comprehensive interpretation of the phenomenon of change orders that occur in the scope of construction, to take preventive action to prevent the occurrence of change orders, and researchers, the results of this study can be used as further study material to develop theories or related topics
