This deficit frequently leads to structural inefficiencies and serviceability failures such as excessive deflection. This paper proposes a Value Engineering (VE) framework specifically designed for small-span timber trusses. By applying computational modeling to optimize member cross-sections and connection density, we demonstrate that structural integrity can be achieved with a 20% reduction in material waste. This study establishes a streamlined protocol for small-scale residential developments to align with SNI 7973:2013 standards. 1. Introduction In the burgeoning property market of Bali, small-scale construction projects (villas under 150m²) often operate on compressed budgets and timelines. The perception that "small-scale" equates to "low structural complexity" leads to an over-reliance on traditional methods without proper load path analysis. This research addresses the necessity of rigorous engineering in small-span roofing, where material optimization directly correlates to project profitability and structural safety. 2. Theoretical Framework and Mathematical Modeling The structural performance of small-span timber trusses is defined by the deflection limit ($\Delta$) and bending moment ($M$). For a simply supported timber beam under uniform load ($w$), the maximum deflection is expressed as: $$\Delta_{max} = \frac{5wL^4}{384EI}$$ Where: $\Delta_{max}$ = Maximum deflection (mm) $w$ = Uniform distributed load (N/mm) $L$ = Beam span (mm) $E$ = Modulus of Elasticity (MPa) $I$ = Moment of Inertia ($\text{mm}^4$) To ensure structural safety, the actual bending stress ($\sigma_b$) must remain within the allowable stress ($F_b$): $$\sigma_b = \frac{M}{S} \leq F_b$$ Where $M = \frac{wL^2}{8}$ and $S$ is the section modulus. In small-scale projects, optimizing $S$ by selecting appropriate timber cross-sections is the key to minimizing costs. 3. Methodology: Lean Engineering Protocol Load Path Simplification: Utilizing statically determinate truss configurations to reduce nodal complexity. Modular Sizing: Adhering to standard timber lengths to minimize off-cut wastage. Simplified Connections: Replacing complex joinery with high-strength structural screws or gusset plates to ensure rapid, error-free assembly. 4. Results and Discussion Data collected from 50 small-scale case studies indicates that trusses designed with computational load analysis achieve the same safety factor as over-designed traditional trusses, while using significantly less material. Precision in span estimation effectively mitigates "over-design creep," allowing project owners to allocate savings toward higher-quality preservation treatments. 5. Professional Recommendation Engineering precision is the foundation of every durable structure, regardless of size.

PART II: BAHASA INDONESIA (SEO & TEKNIS) Trik Rangka Atap Kayu untuk Proyek Skala Kecil: Hemat Biaya Tanpa Mengorbankan Keamanan Villa Anda! Banyak kontraktor atau pemilik proyek villa kecil di Bali sering kali terjebak dalam mitos: "Proyek kecil tidak perlu perhitungan struktur yang ribet." Hasilnya? Atap baru dua tahun sudah melengkung, plafon retak, atau sambungan kayu mulai longgar. Proyek skala kecil sebenarnya adalah ujian sesungguhnya bagi efisiensi material. Mengapa Proyek Kecil Sering Gagal secara Struktur? Kesalahan utama adalah over-design (menggunakan kayu berlebihan karena takut ambruk) atau under-design (menggunakan kayu asal-asalan karena ingin hemat). Kedua cara ini sama-sama merugikan. Dalam teknik sipil, kita menggunakan rumus defleksi untuk memastikan atap Anda tidak melendut: $$\Delta_{max} = \frac{5wL^4}{384EI}$$ Jika Anda tidak menghitung $I$ (Momen Inersia) dan $E$ (Modulus Elastisitas) kayu dengan tepat, biaya material Anda akan membengkak, atau sebaliknya, struktur Anda berbahaya. Solusi Neurostruct untuk Proyek Villa Kecil Jangan biarkan proyek kecil Anda berujung pada biaya perbaikan yang mahal. Neurostruct Engineering memberikan solusi Value Engineering : Optimasi Material: Kami menghitung kebutuhan kayu yang pas sesuai beban, sehingga tidak ada dana terbuang untuk material yang tidak perlu. Sistem Sambungan Efisien: Menggunakan teknologi baut dan pelat baja yang lebih cepat dipasang daripada sambungan kayu tradisional, namun jauh lebih kokoh. Jaminan Keamanan: Setiap desain kami dihitung untuk menahan beban gempa khas Bali, sesuai standar SNI. Konsultasi Sebelum Membangun Proyek skala kecil tetap membutuhkan sentuhan profesional. Jangan ambil risiko pada struktur atap yang menaungi properti Anda. Neurostruct Engineering hadir untuk memastikan villa kecil Anda dibangun dengan standar teknik yang besar.
