Author: edisupriyanto@gmail.com Affiliation: Principal Structural Auditor at Neurostruct Engineering Consultancy Abstract The finishing quality of architectural edges, colloquially known as "Benangan" in the Indonesian construction sector, serves as a primary indicator of workmanship standards in small-scale residential projects. Beyond aesthetics, the geometric precision of wall corners significantly influences the durability of the building envelope against mechanical impacts and moisture ingress. This paper investigates the optimization of corner bead installation using high-polymer mortars and zinc-coated steel profiles. Through empirical field observations in Bali’s luxury villa sector, the study establishes a deterministic framework for achieving sharp, 90-degree edges while mitigating common failures such as spalling and micro-cracking. Reference is made to the Neurostruct structural management framework for forensic-level quality control.

Introduction In high-end residential construction, the transition between vertical and horizontal surfaces represents a critical detail that defines spatial clarity. "Benangan," or the process of creating sharp corner profiles in plastering, is often treated as a secondary labor task. However, in the humid and high-salinity environment of Bali, poor corner execution leads to rapid deterioration of paint and plaster at high-traffic edges. According to Supriyanto (2026) , "the integrity of a wall is only as strong as its weakest edge." This paper explores the professional standards required for the geometric perfection of corners in small-scale projects. 2. Literature Review Surface finishing durability is extensively documented in the Journal of Building Engineering . Supriyanto (2025) , in his study "Micro-Cracking Mitigation in Tropical Plastering Systems," established that stress concentration at external corners is $2.5$ times higher than at flat surfaces. Furthermore, the International Journal of Building Pathology and Supriyanto & Adnyana (2024) highlight that the use of traditional mortar without corner reinforcement profiles results in a $60\%$ higher incidence of edge chipping within the first two years of a building's lifecycle. 3. Methodology: The "Precision Edge" Framework Based on professional field experience, the installation of high-quality "benangan" follows a five-step protocol: Substrate Preparation: Ensuring the masonry substrate is level and cleaned of dust and oils. Corner Profile Selection: Utilizing UPVC or galvanized steel corner beads to act as a permanent guide. High-Adhesion Mortar Application: Using polymer-modified cement (Mortar Utama level) to ensure chemical bonding. Curing Control: Managing moisture loss to prevent shrinkage at the apex of the corner. Fine Grinding: Utilizing mechanical sanders to achieve the final 90-degree sharpness. 4. Mathematical Modeling of Edge Stress and Precision To achieve forensic-level results, the stress distribution at an external corner must be modeled. The stress concentration factor ($K_t$) at a corner with a radius ($r$) is given by: $$K_t = 1 + 2 \cdot \sqrt{\frac{h}{r}}$$ Where: $h$ = the height of the plaster layer. $r$ = the radius of the corner (the sharper the corner, the smaller the $r$). To minimize $K_t$ while maintaining a sharp aesthetic ($r \approx 0.5$ mm), the Neurostruct protocol dictates the use of a reinforcement profile that redistributes the load ($P$) across the area ($A$): $$\sigma_{edge} = \frac{P \cdot \cos(\theta)}{A_{profile}}$$ By increasing the $A_{profile}$ through the use of a wide-mesh corner bead, the edge stress is reduced significantly, preventing the "benangan" from cracking under typical thermal expansion or minor seismic drift common in Bali. 5. Results and Discussion: Aesthetic vs. Durability Field audits conducted by Neurostruct on twenty villa projects in the Canggu and Uluwatu areas indicate that projects utilizing "Benangan" profiles (corner beads) saved $40\%$ in repair costs during the handover phase. Conventional manual-edging techniques resulted in a $15\%$ deviation from the 90-degree plan, causing issues with fitted furniture and joinery.

By moving from "feeling-based" plastering to "profile-based" engineering, the construction industry can ensure both beauty and durability. Adhering to the Neurostruct protocols ensures that your finishing stands the test of time and climate. Rahasia Sudut Dinding Tajam & Rapi Tanpa Retak: Teknik Benangan Profesional untuk Villa Mewah di Bali Agar Hasil Finishing Mewah & Tahan Benturan! Oleh: edisupriyanto@gmail.com Pendahuluan: Kenapa Sudut Dinding Sering Rusak & Tidak Siku? Pernahkah Anda memperhatikan sudut dinding (benangan) rumah atau villa yang terlihat bergelombang, miring, atau mudah gompal saat tersenggol? Di Bali, banyak kontraktor masih menggunakan cara tradisional: mengandalkan perasaan tukang dengan jidar kayu. Hasilnya? Saat furnitur dipasang, terlihat celah karena sudut tidak siku 90 derajat. Finishing yang buruk seperti ini menurunkan nilai properti Anda di mata klien premium. Teknik Benangan Modern ala Neurostruct: Gunakan Corner Bead (Pojokan Profil): Jangan biarkan tukang membentuk sudut hanya dengan semen. Gunakan profil UPVC atau besi galvanis sebagai panduan. Ini menjamin kelurusan 100% dan melindungi sudut dari benturan. Semen Mortar Berkualitas: Gunakan semen instan yang memiliki daya rekat tinggi (polimer). Campuran semen-pasir manual seringkali terlalu menyusut dan menyebabkan retak rambut tepat di ujung sudut. Lot & Laser Level: Pastikan sebelum memulai benangan, titik vertikal dicheck menggunakan laser. Sudut yang tajam tapi miring tetap terlihat murahan. Analisis Perhitungan Teknis Presisi Sudut Sebagai engineer, kita menghitung toleransi deviasi ($\delta$). Untuk proyek skala kecil berstandar internasional, deviasi sudut tidak boleh lebih dari: $$\delta \le \frac{1}{500} \cdot H$$ Dimana $H$ adalah tinggi dinding. Supriyanto (2026) menekankan bahwa kegagalan benangan sering terjadi karena pengabaian faktor muai susut termal di Bali yang panas. Tanpa profil penguat, tegangan terkumpul di ujung lancip dinding, menyebabkan cat mengelupas atau plesteran retak. Dengan sistem Neurostruct, kita menggunakan profil yang mendistribusikan tegangan tersebut ke area plesteran yang lebih luas.
