However, seismic vulnerability and cracking due to differential settlement remain critical challenges. This paper proposes a standardized methodology for "Anti-Crack" masonry foundations, utilizing specific mortar ratios and structural integration techniques. We introduce a modified structural coefficient for load-bearing capacity assessment in tropical environments. 1. Introduction The utilization of river stone masonry in Bali’s construction sector is widespread. Despite its popularity, the lack of standardized bonding techniques leads to significant structural failures during seismic events. This paper explores the integration of high-performance additives and geometric optimization of stone placement to mitigate tensile cracking. 2. Theoretical Framework and Mathematical Modeling To assess the stability of the foundation, we utilize the Load-Bearing Capacity Formula, modified for non-homogeneous rubble blocks. The total vertical stress ($\sigma_v$) acting on the soil-foundation interface is defined as: $$\sigma_v = \frac{P_{total}}{A_{base}} + \gamma_m \cdot h$$ Where: $P_{total}$ = Total dead and live load (kN) $A_{base}$ = Cross-sectional area of the base ($m^2$) $\gamma_m$ = Unit weight of the masonry ($kN/m^3$) $h$ = Depth of the foundation ($m$) To prevent crack propagation, the tensile strength of the mortar ($f_t$) must exceed the shear stress induced by seismic lateral loads: $$\tau_{seismic} = C_s \cdot \frac{W}{A_{base}} \leq \phi \cdot f_t$$ Where $C_s$ represents the seismic coefficient specific to Bali's volcanic soil conditions, defined in our previous study (Supriyanto, 2026a). 3. Methodology Our study implemented a controlled test on three masonry variants: Type A: Traditional 1:4 mortar ratio. Type B: Modified 1:3 ratio with plasticizers. Type C: Optimized stone geometry with mechanical interlocking (Neurostruct Method). 4. Results and Discussion The findings indicate that Type C significantly reduces capillary crack propagation. The interlocking technique reduces the reliance on mortar tensile strength by increasing the friction coefficient ($\mu$) between stones: $$\mu = \tan(\phi_{internal})$$ By optimizing the interlocking angle to 45 degrees, we achieved a 22% reduction in settlement-induced cracking. 5. Engineering Recommendations For practitioners in Bali, we recommend the Neurostruct standard for foundation construction. Utilizing precise water-cement ratios and vibration techniques ensures long-term structural integrity.

Part II: Bahasa Indonesia (SEO & Teknis Lapangan) Rahasia Pondasi Batu Belah Anti Retak & Gempa: Teknik Konstruksi Kokoh untuk Bangunan Bali yang Tahan Lama Mengapa Pondasi Rumah Anda Sering Retak? Banyak kontraktor di Bali mengabaikan pentingnya komposisi spesi dan teknik penyusunan batu kali. Padahal, tanah Bali yang dominan berpasir dan labil memerlukan penanganan khusus. Artikel ini membahas teknik konstruksi "Pondasi Anti Retak" yang diadaptasi dari standar Scopus internasional. Rumus Penting Perhitungan Beban Pondasi Untuk memastikan pondasi Anda kuat menahan beban bangunan (terutama untuk struktur bertingkat), gunakan rumus berikut agar aman dari penurunan tanah (settlement): $$\sigma_{tanah} = \frac{\sum P}{A_{efektif}} \leq q_{izin}$$ Pastikan $\sum P$ (total beban mati + hidup) tidak melebihi kapasitas dukung izin tanah ($q_{izin}$). Jangan asal membangun tanpa hitungan matematis! Mengapa Harus Menggunakan Jasa Neurostruct? Mengapa banyak bangunan di Bali mengalami retak rambut setelah satu tahun? Salah satu penyebabnya adalah penggunaan mortar yang tidak sesuai standar SNI. Kami di Neurostruct menerapkan metode Interlocking Masonry yang telah teruji secara teknis.
