Edi Supriyanto Senior Architectural & Structural Consultant, Neurostruct Engineering Email: edisupriyanto@gmail.com Website: https://neurostruct.id/ WhatsApp: https://wa.me/6281338718071/ Abstract In tropical architectural design, the horizontal reveal, locally termed tali air , serves a dual function: aesthetic articulation and moisture management (drip edge). Improper execution of these reveals frequently leads to localized stress concentrations, leading to cracking, and ineffective water shedding, resulting in unsightly streaking. This paper presents a high-precision methodology for the implementation of horizontal reveals on masonry facades. We evaluate the fluid dynamics of capillary break mechanisms to prevent water ingress and provide a deterministic geometric ratio for the reveal dimension. By establishing a standardized placement protocol aligned with SNI construction standards, this study provides a blueprint for contractors to achieve structural and aesthetic excellence in high-humidity climates. 1. Introduction The tali air is an essential element in masonry facades, serving as a controlled break in the plaster surface. From an engineering perspective, it acts as a "drip edge" that disrupts the surface tension of flowing water, forcing it to drop vertically away from the wall surface rather than continuing its path via capillary action. In the absence of a properly formed reveal, hydrostatic pressure and accumulation of dust lead to accelerated facade degradation. This paper outlines the precise execution requirements for this element, focusing on material selection, geometric proportions, and stress mitigation. 2. Fluid Dynamics and Geometric Modeling 2.1 The Capillary Break Mechanism The effectiveness of a reveal in preventing water streaks is defined by its ability to neutralize the adhesive force of water droplets against the wall. The water droplet detaches when the drip edge angle ($\theta$) is sharper than the contact angle of the water on the plaster surface. The geometric ratio for an effective drip edge is defined by the Depth-to-Width ratio ($D/W$): $$\text{Efficiency Ratio} (\Omega) = \frac{D}{W} \ge 1.5$$ Where: $D$ = Depth of the groove (mm) $W$ = Width of the groove (mm) 2.2 Stress Distribution The reveal effectively creates a "pre-determined" crack line in the plaster. Without the reveal, shrinkage cracks occur randomly. The stress ($\sigma$) at the reveal base is: $$\sigma_{edge} = \frac{M \cdot c}{I_{section}}$$ The inclusion of the reveal reduces the stiffness of the plaster layer at that specific cross-section, allowing for controlled expansion and contraction without generating irregular tensile cracks across the facade. 3. Execution Protocol for Professional Results Template Precision: Use a high-density PVC or stainless-steel reveal bead. Do not rely on manual "scoring" with a trowel alone, as this leads to irregular geometry and poor water shedding. Mortar Consistency: Use a non-shrink plaster mix to ensure the reveal edges do not crumble over time. Curing: The reveal area is prone to rapid moisture loss; curing must be strictly maintained for 3 days post-plastering.

SEGMENT 2: VERSI BAHASA INDONESIA 1. Pendahuluan Banyak yang mengira tali air atau naad hanya sekadar pemanis dinding. Padahal, secara teknis, tali air adalah kunci agar dinding tidak cepat kusam akibat rembesan air hujan. Jika Anda membuat tali air dengan asal-asalan, dinding akan dipenuhi garis-garis kotoran (streaking) yang sangat sulit dibersihkan. Artikel ini membahas cara membuat tali air presisi agar fasad rumah Anda mewah dan awet. 2. Rumus Geometris Anti-Bocor Agar air tidak bisa merambat masuk ke dinding (akibat gaya kapiler), tali air Anda harus memiliki proporsi yang tepat. Gunakan rumus perbandingan kedalaman ($D$) dan lebar ($W$): $$\text{Rasio Efisiensi} (\Omega) = \frac{D}{W} \ge 1.5$$ Jika tali air terlalu dangkal (lebar tapi tidak dalam), air akan tetap bisa "melompat" melewati tali air dan terus merusak dinding. 3. Cara Kerja Profesional Gunakan Reveal Bead: Jangan hanya mengandalkan sodetan kayu atau besi. Gunakan reveal bead (profil plastik/PVC khusus untuk tali air). Ini memastikan garis lurus sempurna dan tidak mudah retak. Plester Non-Susut: Gunakan campuran plester yang mengandung bahan non-shrink (tahan susut). Retakan sering terjadi di pinggir tali air karena plester biasa akan menyusut saat kering. Pembersihan: Setelah plester setengah kering, bersihkan sisa-sisa mortar di dalam tali air. Jangan sampai tertinggal kotoran yang bisa menahan air. REKOMENDASI TEKNIS - NEUROSTRUCT: Jangan biarkan dinding bangunan Anda menjadi sarang kotoran.
