Abstract
Dalam pembangunan Jalan Tol Pasuruan – Probolinggo STA 36, terdapat analisa struktur dasar bangunan yakni pondasi struktur bangunan. Pondasi adalah kerangka awal yang sangat penting untuk menahan konstruksi di atasnya. Pondasi yang digunakan pada area tersebut adalah pondasi bored pile. Oleh sebab itu, untuk meminimalisir terjadinya keruntuhan pondasi, dapat dilakukan analisa daya dukung. Pada penelitian di area tersebut digunakan dua metode yaitu metode geofisika dan metode geoteknik untuk validasi kedalaman serta area yang memiliki nilai daya dukung yang sesuai. Metode geofisika yang digunakan adalah metode geolistrik Vertical Electrical Sounding (VES) untuk mengetahui lokasi kedalaman tanah keras pada area tersebut. Hasil interpretasi VES dikorelasikan dengan data bor serta jumlah N-SPT pada masing – masing titik pengukuran. Berdasarkan hasil interpretasi tersebut, dapat memperluas target area yang diteliti untuk mengidentifikasi jenis tanah pada bawah permukaan. Dengan informasi tersebut, dapat dilakukan perhitungan daya dukung berdasarkan N-SPT serta daya dukung berdasarkan Pile Driving Analyzer Test (PDA Test). Pada hasil pengolahan VES didapatkan informasi jenis tanah berdasarkan nilai resistivitas yang terdapat pada kedalaman 25 meter. Pada kedalaman 25 meter, didapatkan hasil daya dukung tanah (N-SPT) dengan metode Meyerhoff pada STA 36+250 dan STA 36+275 sebesar 870.56 ton dan 839.73 ton dan daya dukung tanah (N-SPT) metode Luciano Decourt didapatkan nilai daya dukung sebesar 744.46 ton dan 809.69 ton. Sedangkan daya dukung pondasi berdasarkan PDA test pada kedua area tersebut menggunakan nilai working load sebesar 800 ton dan hasil perhitungan nilai daya dukung pondasi menggunakan CAPWAP software menunjukkan nilai sebesar 1147.74 ton dan 1103.87 ton. Berdasarkan perhitungan daya dukung secara analitis dan PDA test didapatkan bahwa pondasi bored pile pada Jalan Tol Pasuruan – Probolinggo STA 36 pada titik sekitar area STA 36+250 dan STA 36+275 relatif aman dan sesuai. Hal tersebut juga ditunjukkan oleh hasil interpretasi VES yang menunjukkan bahwa pada kedalaman 25 meter pada STA 36 merupakan kedalaman yang telah sesuai dijadikan sebagai sebuah ujung pondasi bored pile.

In the construction of the Pasuruan – Probolinggo STA 36 Toll Road, there is an analysis of the basic structure of the building, namely the foundation of the building structure. The foundation is the initial framework that is very important to hold the construction on it. The foundation used in this area is the bored pile foundation. Therefore, to minimize the occurrence of foundation collapse, carrying capacity analysis can be carried out. In research in this area, two methods are used, namely the geophysical method and the geotechnical method to validate the depth and area that has the appropriate carrying capacity value. The geophysical method used is the Vertical Electrical Sounding (VES) geoelectric method to determine the location of the hard soil depth in the area. The results of the VES interpretation were correlated with drill data and the amount of N-SPT at each measurement point. Based on the results of this interpretation, it can expand the target area under study to identify the type of soil below the surface. With this information, it is possible to calculate the carrying capacity based on the N-SPT and the carrying capacity based on the Pile Driving Analyzer Test (PDA Test). The results of VES processing obtained soil type information based on the resistivity value found at a depth of 25 meters. At a depth of 25 meters, the soil bearing capacity (N-SPT) using the Meyerhoff method at STA 36+250 and STA 36+275 was 870.56 tons and 839.73 tons and the soil bearing capacity (N-SPT) Luciano Decourt's method was obtained. of 744.46 tons and 809.69 tons. While the bearing capacity of the foundation based on the PDA test in both areas uses a working load value of 800 tons and the results of the calculation of the bearing capacity value of the foundation using CAPWAP software show a value of 1147.74 tons and 1103.87 tons. Based on the analytical carrying capacity calculation and PDA test, it was found that the bored pile foundation on the Pasuruan – Probolinggo Toll Road STA 36 at points around the STA 36+250 and STA 36+275 areas is relatively safe and appropriate. This is also shown by the results of the VES interpretation which shows that at a depth of 25 meters at STA 36 is the appropriate depth to be used as an end of the bored pile foundation.
