| Abstract: | Pembangunan konstruksi memerlukan perencanaan yang matang, khususnya dalam aspek geoteknik yang sangat bergantung pada kondisi tanah di lokasi pembangunan. Salah satu parameter utama dalam menentukan stabilitas dan kelayakan struktur adalah daya dukung tanah.Penelitian ini menganalisis korelasi nilai Standard Penetration Test (SPT) terhadap estimasi daya dukung tanah pada proyek pembangunan Masjid Al Qurban di Lam Ara, Banda Aceh. Metode yang digunakan meliputi Schmertman, Luciano Decourt, dan Bowles untuk menghitung daya dukung tiang spun pile berdasarkan data SPT dan uji laboratorium. Hasil penelitian menunjukkan bahwa metode Schmertman memberikan estimasi daya dukung yang mendekati nilai proyek dengan persentase kesesuaian berkisar antara 78,9% hingga 156,8%, sedangkan metode Luciano Decourt persentase kesesuian berkisar antara 77,2% hingga 120,2% menunjukkan hasil yang konsisten. sedangkan metode Bowles persentase kesesuaian berkisar antara 60% hingga 127% ini juga menunjukkan hasil yang konsisten. Berdasarkan analisis statistik, metode Schmertman dan Bowles menunjukkan korelasi yang sangat kuat antara nilai N-SPT dan daya dukung tanah dengan nilai R² masing-masing sebesar 0,912 dan 0,9303, sedangkan metode Luciano Decourt memiliki R² sebesar 0,6815. Dari hasil analisis perhitungan untuk ketiga metode ini menunjukan bahwa metode Luciano Decourt lebih mendekati hasil dari daya dukung yang ada di proyek lalu disusul dengan metode Bowles dan kemuadian Schmertman. Perbandingan ketiga metode ini memberikan gambaran praktis dalam pemilihan metode perhitungan daya dukung tanah yang sesuai untuk proyek konstruksi serupa. Construction requires careful planning, particularly in geotechnical aspects, which are highly dependent on soil conditions at the construction site. One of the main parameters in determining the stability and feasibility of a structure is the bearing capacity of the soil. This study analyzes the correlation between Standard Penetration Test (SPT) values and estimated soil bearing capacity for the Al Qurban Mosque construction project in Lam Ara, Banda Aceh. The methods used included Schmertman, Luciano Decourt, and Bowles to calculate the bearing capacity of spun piles based on SPT data and laboratory tests. The results of the study indicate that the Schmertman method provides bearing capacity estimates that are close to the project values, with a percentage agreement ranging from 78.9% to 156.8%. The Luciano Decourt method has a percentage agreement ranging from 77.2% to 120.2%, indicating consistent results. The Bowles method, on the other hand, has a percentage agreement ranging from 60% to 127%, also showing consistent results. Based on statistical analysis, the Schmertman and Bowles methods showed a very strong correlation between the N-SPT value and soil bearing capacity, with R² values of 0.912 and 0.9303, respectively, while the Luciano Decourt method had an R² of 0.6815. The analysis of the calculations for these three methods showed that the Luciano Decourt method was closer to the bearing capacity results for the project, followed by the Bowles method and then the Schmertman method. This comparison of the three methods provides practical insights into selecting the appropriate soil bearing capacity calculation method for similar construction projects. |
