This paper presents a cost-efficient strategy for utilizing CPT data in accordance with Indonesian National Standards (SNI) to optimize pile depth, minimize construction costs, and ensure structural safety. The study emphasizes practical application in tropical regions such as Bali, where soil variability significantly influences foundation performance. 1. Introduction Foundation failure is often caused by inadequate soil investigation. The CPT method provides continuous soil resistance data, enabling engineers to design pile foundations accurately. This research highlights how CPT can be used effectively to reduce overdesign and unnecessary construction costs. 2. Fundamentals of Cone Penetration Test (CPT) 2.1 Principle of CPT CPT measures: Cone resistance (qc) Sleeve friction (fs) Pore water pressure (u) These parameters help classify soil layers and determine bearing capacity. 2.2 Key Equation for Tip Resistance q_c = \frac{F_c}{A_c} Where: ( q_c ) = cone resistance ( F_c ) = measured force ( A_c ) = cone area 3. Determining Pile Capacity from CPT Data 3.1 End Bearing Capacity Q_b = q_c \cdot A_b 3.2 Skin Friction Capacity Q_s = \sum f_s \cdot A_s 3.3 Total Pile Capacity [ Q_{ult} = Q_b + Q_s ] This equation ensures that both tip resistance and shaft friction are considered. 4. SNI-Based Design Approach According to SNI standards: Safety factor (SF): 2.5–3 Allowable capacity: [ Q_{all} = \frac{Q_{ult}}{SF} ] 5. Cost-Efficiency Strategy 5.1 Avoid Overdesign Using CPT data reduces unnecessary pile length. 5.2 Optimize Pile Depth Stop pile penetration when qc indicates sufficient bearing layer. 5.3 Soil Layer Interpretation Soft soil → low qc → deeper piles Dense soil → high qc → shorter piles 6. Case Study: Bali Soil Conditions Typical findings: Coastal areas: loose sand → deeper piles Urban Denpasar: mixed clay → moderate depth Highland areas: dense volcanic soil → shallow piles 7. Common Mistakes in CPT Application Issue Cause Solution Misinterpretation of qc Lack of expertise Use software analysis Overly conservative design High safety factor Optimize SF Ignoring groundwater Incomplete data Include pore pressure 8.

Artikel ini membahas strategi hemat biaya dengan memanfaatkan data CPT sesuai standar SNI untuk menghasilkan desain fondasi yang aman dan ekonomis, khususnya di wilayah Bali. 1. Pendahuluan Kegagalan fondasi sering terjadi akibat kurangnya investigasi tanah. CPT memberikan data kontinu yang sangat akurat untuk perencanaan fondasi dalam. 2. Dasar Tes Sondir 2.1 Parameter CPT Tahanan ujung (qc) Gesekan selimut (fs) Tekanan air pori 2.2 Rumus Tahanan Ujung q_c = \frac{F_c}{A_c} 3. Kapasitas Tiang dari Data CPT 3.1 Daya Dukung Ujung Q_b = q_c \cdot A_b 3.2 Gesekan Selimut Q_s = \sum f_s \cdot A_s 4. Pendekatan SNI Faktor keamanan: 2.5–3 Kapasitas izin dihitung dari kapasitas ultimit 5. Strategi Hemat Biaya Hindari desain berlebihan Optimalkan kedalaman tiang Gunakan interpretasi lapisan tanah 6. Kondisi Tanah Bali Pantai → tanah lunak → tiang dalam Perkotaan → tanah campuran Pegunungan → tanah keras 7.
