Abstract

Soil shear strength is an important component in infrastructure design. Many tests can be carried out to determine the shear strength of soil. The Cone Penetration Test (CPT) is a test commonly carried out to predict the shear strength of soil. Dynamic Cone Penetrometer (DCP) is often used to predict the value of soil shear strength in the form of the California Bearing Ratio (CBR) to determine the thickness of highway pavement. The shear strength of clay soil for building design purposes is usually expressed in undrained cohesion (cu) which can be obtained from CPT testing. With DCP and CPT tests carried out at the same location, the relationship between the shear strength parameters from these tests will be obtained. The results obtained were CBR = 0.2504 qc(kg/cm2) and cu (kPa) = 14.455 CBR (%). It is hoped that these results will be a rough estimate for road pavement design because DCP testing is limited in its use (only 1 m subgrade depth).

Abstract

The settlement characteristics of driven piles and bored piles vary depending on installation methods and subsurface conditions, necessitating accurate evaluation of foundation performance. This study aims to compare the settlement behavior of these two foundation types based on Pile Driving Analyzer (PDA) test results evaluated with reference to ASTM D1143 standards. Data were collected from 31 PDA test points across various projects in Riau Province, covering both driven and bored pile foundations. The analysis was conducted by comparing the maximum settlement values (DMX) obtained from PDA with the allowable maximum settlement (Sf) calculated according to ASTM D1143. The ratio between the actual data and the standard was assessed to determine settlement compliance. The results indicate that several driven and bored piles still exhibit settlement beyond the allowable limit, where the maximum settlement ratio DMX/Sf must be less than 1.00. Additionally, the presence of free-end type curves suggests excessive settlement in several samples. This study provides an important contribution to improving the accuracy of foundation capacity evaluation and serves as a basis for selecting and optimizing foundation design in sustainable infrastructure projects.

Abstract

The selection of deep excavation retaining systems in Indonesian clay soils is commonly performed based on practical experience without systematic parametric guidance. This study develops selection criteria between diaphragm walls and secant piles through a comprehensive parametric study using the finite element method. A total of 216 numerical models were simulated using Optum G2 software, varying wall type (diaphragm wall and secant pile), excavation depth (4, 8, and 12 m), groundwater table position, building surcharge load (25 kN/m), soil type (soft clay with N-SPT = 4 and stiff clay with N-SPT = 15), and constitutive model (Mohr-Coulomb and Hardening Soil). Results demonstrate that the Hardening Soil model produces 30–39% lower deformations compared to Mohr-Coulomb. Secant piles proved more cost-efficient across all 216 scenarios analyzed, achieving up to 50% cost savings for shallow excavations under low-risk conditions. The most influential parameters on wall performance are, in order: soil type, excavation depth, groundwater table position, constitutive model, surcharge load, and wall type. The resulting design charts and decision matrices serve as preliminary design tools within the SNI 8460-2017 framework.

Abstract

Kegiatan konstruksi mengandung beragam sumber bahaya yang dapat menimbulkan kecelakaan kerja, sehingga penerapan Keselamatan dan Kesehatan Kerja (K3), terutama kedisiplinan dalam memakai Alat Pelindung Diri (APD), menjadi kebutuhan utama di area proyek. Salah satu bentuk intervensi yang dapat digunakan untuk memperkuat perilaku aman pekerja adalah safety talk yang diberikan sebelum aktivitas pekerjaan dimulai. Penelitian ini mengevaluasi pengaruh pelaksanaan safety talk terhadap tingkat kepatuhan penggunaan APD pada pekerja Proyek Pengembangan Rumah Sakit X Pekanbaru. Metode yang digunakan adalah pendekatan kuantitatif dengan rancangan one group pre-test post-test. Sebanyak 30 pekerja dilibatkan sebagai sampel melalui teknik total sampling. Data diperoleh melalui observasi kepatuhan APD sebelum dan setelah safety talk, dengan komponen penilaian meliputi helm keselamatan, kacamata pelindung, pelindung telinga, masker, sarung tangan, sepatu safety, dan rompi. Analisis dilakukan melalui statistik deskriptif serta Wilcoxon Signed Rank Test. Hasil penelitian memperlihatkan bahwa rerata kepatuhan APD sebelum intervensi adalah 3,67 atau 52,38%, sedangkan setelah safety talk meningkat menjadi 6,17 atau 88,10%. Uji Wilcoxon menghasilkan nilai Z= -4,79, p < 0,001, dan effect size r = 0,87, yang mengindikasikan adanya perbedaan signifikan dengan efek yang kuat antara kepatuhan sebelum dan sesudah intervensi. Temuan ini menunjukkan bahwa safety talk berperan efektif dalam mendorong kepatuhan pekerja konstruksi terhadap penggunaan APD.

Abstract

Accurate prediction of the axial bearing capacity of pile foundations is essential for ensuring structural safety and optimizing foundation design. Although static prediction methods based on Cone Penetration Test (CPT) data are widely used because of their simplicity and cost-effectiveness, their predictive accuracy varies depending on the adopted analytical approach. This study evaluates the performance of three commonly used static methods (Meyerhof, Schmertmann, and Terzaghi) in predicting the axial bearing capacity of precast concrete minipiles using Pile Driving Analyzer (PDA) test results as the field reference. The analysis was conducted using CPT data collected from six sounding locations at a two-story residential building project in Pekanbaru, Indonesia. The predicted bearing capacities obtained from each method were compared with the ultimate capacity derived from PDA and CAPWAP analyses using absolute and relative differences as evaluation indicators. The results show that all three static methods overestimated the measured pile capacity, although the magnitude of deviation varied considerably. The Schmertmann method produced the highest average predicted capacity (50.35 tons), followed by the Meyerhof method (37.08 tons), while the Terzaghi method yielded the lowest prediction (33.54 tons). Compared with the PDA-derived ultimate capacity of 30.10 tons, the Terzaghi method exhibited the smallest relative difference (11.43%), indicating the closest agreement with field measurements. CAPWAP analysis further revealed that approximately 90.7% of the pile capacity was mobilized through shaft resistance, confirming the predominance of frictional load transfer at the study site. These findings demonstrate that the Terzaghi method provides the most representative prediction of minipile axial bearing capacity under the investigated soil conditions and may serve as a practical alternative for preliminary foundation design when field load testing is unavailable.

Abstract

This community service program addressed occupational safety and health (OSH) problems in a home-based lightweight brick industry in Pekanbaru, including cement and sand dust, manual material handling, obstructed work pathways, disorganized material storage, and inconsistent use of personal protective equipment (PPE). The program aimed to improve OSH knowledge, PPE compliance, and workplace conditions through integrated education and participatory workplace assistance. A descriptive pre-post approach was applied to 25 participants, with 10 active workers serving as the primary targets for behavioral and workplace observations. Activities comprised initial situation analysis, OSH education, PPE demonstrations, participatory hazard identification, workplace arrangement, installation of safety posters, and evaluation using pre-test/post-test instruments, observation sheets, and workplace checklists. The indicator scores increased from 42% to 82% for OSH knowledge, from 48% to 85% for PPE compliance, and from 50% to 87% for workplace conditions. The program also produced designated storage areas, clearer worker pathways, and on-site OSH educational media. These findings indicate immediate improvements after the intervention; however, sustained implementation requires simple work procedures, designated responsibility, and periodic monitoring.

Abstract

Penelitian ini membahas perencanaan teknis bangunan bawah jembatan, khususnya abutment pada Jembatan Rangka Baja Sungai Rokan Kiri di Kota Tengah, Kabupaten Kampar. Metode penelitian yang digunakan meliputi studi literatur dan studi desain, dengan pengumpulan data primer berupa hasil sondir, data tanah, topografi, serta hidrografi aliran sungai. Analisis dilakukan terhadap beban yang bekerja pada abutment, meliputi beban vertikal, beban horizontal, serta tekanan tanah lateral. Faktor keamanan terhadap geser (SF-{geser}) dan guling (SF-{guling}) dihitung untuk memastikan stabilitas konstruksi. Hasil perhitungan menunjukkan bahwa abutment yang direncanakan memenuhi kriteria keamanan yang dipersyaratkan, baik terhadap gaya geser maupun gaya guling, sesuai dengan standar peraturan Departemen Pekerjaan Umum. Dengan demikian, rancangan bangunan bawah jembatan ini dapat dinyatakan layak secara teknis dan aman digunakan dalam mendukung beban lalu lintas di atasnya.   This study discusses the technical planning of bridge substructures, particularly the abutment of the Steel Truss Bridge over the Rokan Kiri River in Kota Tengah, Kampar Regency. The research methods employed include a literature review and design study, with primary data collection consisting of cone penetration test (CPT) results, soil data, topographic data, and river flow hydrology data. The analysis focuses on the loads acting on the abutment, including vertical loads, horizontal loads, and lateral earth pressure. Safety factors against sliding (SF_sliding) and overturning (SF_overturning) are calculated to ensure the structural stability of the abutment. The calculation results indicate that the planned abutment meets the required safety criteria against both sliding and overturning forces in accordance with the standards set by the Ministry of Public Works. Therefore, the design of the bridge substructure can be considered technically feasible and safe to support traffic loads above it.

Abstract

Evaluasi time schedule pada proyek pembangunan pengaman pantai pulau terluar provinsi Riau berawal dengan membuat WBS (Work Breakdown Structure) kemudian menghitung ulang durasi pekerjaan, dilanjutkan dengan men-tracking item pekerjaannya pada Microsoft Project. Pada WBS proyek ini diperoleh urutan sub pekerjaaan yang terdiri dari persiapan, mobilisasi, kegiatan K3, pekerjaan cerucuk, pemasangan geotextile, pemasangan batu, dan demobilisasi. Hasil perhitungan ulang durasi pekerjaan pada time schedule proyek diperoleh selama 236 hari. Dimana untuk pekerjaan persiapan selama 16 hari, pekerjaan mobilisasi 21 hari, pekerjaan K3 229 hari, pekerjaan cerucuk 196 hari, pekerjaan geotextile 35 hari, pemasangan batu 115 hari, dan pekerjaan demobilisasi 21 hari. Lintasan kritis dihasilkan dari pengolahan software Microsoft Project pada item pekerjaan persiapan, mobilisasi, pekerjaan cerucuk, pemasangan batu, dan demobilisasi. Hasil tracking yang telah dilakukan dengan Microsoft Project menghasilkan pergeseran durasi penyelesaian pekerjaan yaitu lebih kurang satu bulan dari yang seharusnya dapat diselesaikan. Terdapat perbedaan durasi pengerjaan proyek yaitu dimana durasi pada time schedule awal selama 270 hari, sedangkan pada time schedule yang telah dievaluasi dengan bantuan Microsoft project pekerjaan dapat diselesaikan dengan durasi 236 hari.
