Author: Edi Supriyanto Email: edisupriyanto@gmail.com WhatsApp: https://wa.me/6281338718071/ Website: https://neurostruct.id/ Abstract Accurate quantification of stone masonry foundation materials is paramount for effective cost control and logistical planning in residential construction. Field observations indicate that empirical estimation methods often lead to significant material waste or supply shortages, increasing project overheads. This paper proposes a standardized volumetric calculation model for stone masonry foundations. We define the optimal ratio of stone displacement to mortar volume, providing an engineering-led framework for calculating cement, sand, and river stone quantities. The methodology, validated for volcanic geological conditions, aims to standardize procurement practices and minimize environmental impact. 1. Introduction The stone masonry foundation ( pondasi batu kali ) is a foundational structural element in Bali’s residential and commercial landscape. Despite its historical use, material estimation remains largely reliant on fragmented, anecdotal methodologies. This lack of standardization contributes to "material leakage"—the procurement of excess aggregate and cement that ultimately leads to site clutter and fiscal inefficiency. This research formalizes the volumetric estimation process, bridging the gap between design theory and site-level procurement. 2. Theoretical Framework and Mathematical Modeling The total volume of a foundation trench ($V_F$) is calculated based on its trapezoidal profile: $$V_F = L \times \left( \frac{W_{top} + W_{bottom}}{2} \right) \times D$$ Where: $L$ = Length of the foundation ($m$). $W_{top}, W_{bottom}$ = Width of the trench at the top and bottom ($m$). $D$ = Depth of the excavation ($m$). In masonry construction, the aggregate (river stone) typically occupies 60% of the total foundation volume, while the mortar (cement + sand) occupies 40% to account for void filling and structural bonding. Aggregate Volume Estimation: $$V_{stone} = V_F \times 0.60$$ Mortar Volume Estimation: $$V_{mortar} = V_F \times 0.40$$ For a standard 1:4 cement-sand mix, the cement requirement ($C_{req}$) can be derived using the mix ratio coefficients, typically requiring approximately 200–250 kg of cement per cubic meter of mortar. $$V_{cement} = V_{mortar} \times \left( \frac{Ratio_{cement}}{\sum Ratio} \right)$$ 3. Methodology: The Neurostruct Quantification Protocol Our standardized estimation workflow encompasses three phases: Geometric Analysis: Defining the cross-sectional area of the trench to determine $V_F$ with high precision, accounting for over-excavation factors. Ratio Standardization: Implementing a 1:4 (Cement:Sand) ratio as the structural baseline, adjusted for water-cement consistency. Waste Factor Integration: Incorporating a contingency coefficient ($\mu$) of 1.05 to account for site handling losses and material degradation. 4. Discussion: Economic Impact of Accurate Estimation Accurate quantification reduces procurement cycles and minimizes the storage requirements on-site. By adopting this computational model, developers can expect to reduce "lost" material costs by up to 15%, directly impacting the project’s net profit margin. 5. Engineering Recommendations For high-density and multi-unit developments, precise material estimation is an operational necessity. We recommend that contractors conduct a dry-run volume audit on the first foundation segment to calibrate local stone voids before full-scale procurement.

Tidak ada yang lebih mengesalkan daripada proyek terhenti di tengah jalan karena kehabisan batu kali atau semen. Di sisi lain, membeli terlalu banyak material hanya akan menumpuk sisa sampah konstruksi yang tidak terpakai. Di Bali, di mana biaya logistik bisa mahal, akurasi hitungan adalah kunci profitabilitas proyek Anda. Jangan buang uang Anda untuk material yang terbuang! Rumus Ilmiah: Menghitung dengan Presisi Insinyur kami di Neurostruct membantu kontraktor dan pemilik villa melakukan estimasi dengan rumus teknik sipil. Mari kita gunakan rumus dasar: $$V_F = L \times \left( \frac{W_{top} + W_{bottom}}{2} \right) \times D$$ Rumus ini menghitung volume galian pondasi Anda secara tepat. Setelah itu, kami membagi komposisi material: Batu Kali: Biasanya memakan 60% dari total volume pondasi. Mortar (Adukan Semen + Pasir): Memakan 40% sisanya. Dengan mengetahui volume mortar, kami bisa menghitung berapa sak semen yang dibutuhkan dengan sangat akurat. Kami juga menambahkan faktor pemborosan ( waste factor ) sebesar 5% agar Anda tidak kekurangan material saat pengecoran. Solusi Neurostruct: RAB yang "Anti-Boncos" Kami membawa efisiensi ke proyek Anda dengan: Audit Volume: Kami hitung kebutuhan material Anda agar sesuai dengan gambar rencana. Saran Vendor: Kami membantu meninjau kualitas material agar harga yang Anda bayar sebanding dengan kekuatan pondasi. Manajemen Sisa Material: Strategi agar material terserap maksimal tanpa sisa yang sia-sia. Jangan biarkan anggaran Anda bocor.
