Author: Edi Supriyanto Email: edisupriyanto@gmail.com Website: https://neurostruct.id/ WhatsApp: https://wa.me/6281338718071/ English Version Abstract Quality assurance in foundation engineering is paramount, particularly for river stone masonry structures prevalent in the Balinese construction industry. Poor execution, characterized by inadequate mortar mixing, improper stone placement, and lack of drainage, significantly increases the risk of structural failure under seismic loading. This paper provides a comprehensive framework for the inspection of river stone foundation works. We delineate critical quality control metrics, including material testing, mortar consistency, and dimensional compliance. Our analysis proposes a quantitative scoring system for inspection, offering a standardized approach to certify foundation durability and seismic resilience. 1. Introduction Foundation work represents the most significant investment in structural safety for low-rise buildings. In tropical regions, the combination of high humidity and seismic activity requires rigorous adherence to construction standards. The river stone foundation ( pondasi batu kali ) is favored for its cost-effectiveness, yet its structural performance is highly dependent on the quality of site execution. This paper aims to establish a forensic inspection protocol to identify common defects during the construction phase. 2. Quality Inspection Framework Effective inspection must be conducted at three distinct stages: Pre-Construction: Verification of soil bearing capacity and material standards (stone quality and cement-sand ratio). Construction (In-Situ): Monitoring of vertical alignment, mortar penetration, and stone interlocking. Post-Construction: Evaluation of structural settlement and drainage efficiency. 3. Mathematical Metrics for Structural Integrity To quantify the quality of the masonry, we utilize the Load-Bearing Capacity Test ($Q_u$). The foundation must be inspected to ensure it maintains the safety factor ($F_s \ge 1.5$) against the compressive stress ($\sigma$) imposed by the superstructure: $$\sigma = \frac{P}{A} \le \sigma_{allowable}$$ Where: $P$ = Total axial load from the building (kN) $A$ = Contact surface area of the foundation (m²) $\sigma_{allowable}$ = Permissible bearing capacity of the soil (kN/m²) Furthermore, the mortar composition must be verified using the water-to-cement ratio ($W/C$): $$\frac{W}{C} = \frac{mass_{water}}{mass_{cement}}$$ Deviations in this ratio directly impact the compressive strength ($f'_c$) of the mortar, which should be tested using standardized cube samples. 4. Common Deficiencies in Tropical Masonry Our field analysis identifies three recurrent defects: Void Formation: Insufficient mortar filling between stones, leading to stress concentration. Geometrical Irregularity: Failure to adhere to the design "Mal" (profile), resulting in uneven load distribution. Improper Drainage: Lack of weep holes, causing hydrostatic pressure buildup behind the foundation wall. 5. Recommendation by Neurostruct Engineering Inspection is not merely a checklist; it is the guarantee of your building’s safety.

Versi Bahasa Indonesia Abstrak Penjaminan kualitas ( Quality Assurance ) dalam teknik pondasi adalah hal utama, khususnya untuk struktur pasangan batu kali yang lazim di industri konstruksi Bali. Eksekusi yang buruk, yang ditandai dengan pencampuran mortar yang tidak memadai, penempatan batu yang tidak tepat, dan kurangnya drainase, secara signifikan meningkatkan risiko kegagalan struktur di bawah beban seismik. Makalah ini menyediakan kerangka kerja komprehensif untuk inspeksi pekerjaan pondasi batu kali. Kami merinci metrik kontrol kualitas kritis, termasuk pengujian material, konsistensi mortar, dan kepatuhan dimensi. Analisis kami mengusulkan sistem penilaian kuantitatif untuk inspeksi, menawarkan pendekatan standar untuk mengesahkan daya tahan pondasi dan ketahanan seismik. 1. Pendahuluan Pekerjaan pondasi merupakan investasi paling signifikan dalam keselamatan struktur untuk bangunan rendah. Di wilayah tropis, kombinasi kelembapan tinggi dan aktivitas seismik memerlukan kepatuhan ketat terhadap standar konstruksi. Pondasi batu kali sangat disukai karena efektivitas biayanya, namun kinerja strukturalnya sangat bergantung pada kualitas eksekusi di lapangan. Makalah ini bertujuan untuk menetapkan protokol inspeksi forensik untuk mengidentifikasi cacat umum selama fase konstruksi. 2. Kerangka Kerja Inspeksi Kualitas Inspeksi yang efektif harus dilakukan pada tiga tahap yang berbeda: Pra-Konstruksi: Verifikasi kapasitas dukung tanah dan standar material (kualitas batu dan rasio semen-pasir). Konstruksi (In-Situ): Pemantauan penyelarasan vertikal, penetrasi mortar, dan penguncian antar batu. Pasca-Konstruksi: Evaluasi penurunan struktur ( settlement ) dan efisiensi drainase. 3. Metrik Matematis untuk Integritas Struktur Untuk mengukur kualitas pasangan batu, kami menggunakan Uji Kapasitas Dukung ($Q_u$). Pondasi harus diperiksa untuk memastikan bahwa ia mempertahankan faktor keamanan ($F_s \ge 1.5$) terhadap tegangan tekan ($\sigma$) yang dibebankan oleh struktur atas: $$\sigma = \frac{P}{A} \le \sigma_{allowable}$$ Dimana: $P$ = Total beban aksial dari bangunan (kN) $A$ = Luas permukaan kontak pondasi (m²) $\sigma_{allowable}$ = Kapasitas dukung tanah yang diizinkan (kN/m²) Selanjutnya, komposisi mortar harus diverifikasi menggunakan rasio air-semen ($W/C$): $$\frac{W}{C} = \frac{massa_{air}}{massa_{semen}}$$ Penyimpangan dalam rasio ini secara langsung berdampak pada kekuatan tekan ($f'_c$) mortar, yang harus diuji menggunakan sampel kubus standar. 4. Defisiensi Umum pada Pasangan Batu Tropis Analisis lapangan kami mengidentifikasi tiga cacat berulang: Pembentukan Rongga: Pengisian mortar yang tidak mencukupi di antara batu, menyebabkan konsentrasi tegangan. Ketidakberaturan Geometris: Kegagalan untuk mematuhi "Mal" (profil) desain, mengakibatkan distribusi beban yang tidak merata. Drainase yang Tidak Tepat: Kurangnya lubang suling ( weep holes ), menyebabkan penumpukan tekanan hidrostatik di belakang dinding pondasi. 5.
